We are now trying to release all our books one month in advance
of the official release dates, for time for better editing.

Please note:  neither this list nor its contents are final till
midnight of the last day of the month of any such announcement.
The official release date of all Project Gutenberg Etexts is at
Midnight, Central Time, of the last day of the stated month.  A
preliminary version may often be posted for suggestion, comment
and editing by those who wish to do so.  To be sure you have an
up to date first edition [xxxxx10x.xxx] please check file sizes
in the first week of the next month.  Since our ftp program has
a bug in it that scrambles the date [tried to fix and failed] a
look at the file size will have to do, but we will try to see a
new copy has at least one byte more or less.


Information about Project Gutenberg (one page)

We produce about two million dollars for each hour we work.  The
fifty hours is one conservative estimate for how long it we take
to get any etext selected, entered, proofread, edited, copyright
searched and analyzed, the copyright letters written, etc.  This
projected audience is one hundred million readers.  If our value
per text is nominally estimated at one dollar then we produce $2
million dollars per hour this year as we release thirty-two text
files per month:  or 400 more Etexts in 1996 for a total of 800.
If these reach just 10% of the computerized population, then the
total should reach 80 billion Etexts.

The Goal of Project Gutenberg is to Give Away One Trillion Etext
Files by the December 31, 2001.  [10,000 x 100,000,000=Trillion]
This is ten thousand titles each to one hundred million readers,
which is only 10% of the present number of computer users.  2001
should have at least twice as many computer users as that, so it
will require us reaching less than 5% of the users in 2001.

THE EVOLUTION OF THE STARS AND THE FORMATION OF THE EARTH. II

BY DR. WILLIAM WALLACE CAMPBELL

DIRECTOR OF THE LICK OBSERVATORY, UNIVERSITY OF CALIFORNIA

THE PRINCIPLES OF SPECTROSCOPY

THUS far our description of the stellar universe has been
confined to its geometrical properties. A serious study of the
evolution of the stars must seek to determine, first of all,
what the stars really are, what their chemical constitutions
and physical conditions are; and how they are related to each
other as to their physical properties. The application of the
spectroscope has advanced our knowledge of the subject by leaps
and bounds. This wonderful instrument, assisted by the
photographic plate, enables every visible celestial body to
write its own record of the conditions existing in itself,
within limits set principally by the brightness of the body.
Such records physicists have succeeded to some extent in
duplicating in their laboratories; and the known conditions
under which the laboratory experiments have been conducted are
the Rosetta Stones which are enabling us to interpret, with
more or less success, the records written by the stars.

It is well known that the ordinary image of a star, whether
formed by the eye alone, or by the achromatic telescope and the
eye combined, contains light of an infinite variety of colors
corresponding, speaking according to the mechanical theory of
light, to waves of energy of an infinite variety of lengths
which have traveled to us from the star. In the point image of
a star, these radiations fall in a confused heap. and the
observer is unable to say that radiations corresponding to any
given wave-lengths are present or absent. When the star's light
has been passed through the prism, or diffracted from the
grating of a spectroscope, these rays are separated one from
another and arranged side by side in perfect order, ready for
the observer to survey them and to determine which ones are
present in superabundance and which other ones are lacking
wholly or in part. The following comparison is a fair one: the
ordinary point image of a star is as if all the books in the
university library were thrown together in a disorderly but
compact pile in the center of the reading room: we could say
little concerning the contents and characteristics of that
library; whether it is strong in certain fields of human
endeavor, or weak in other fields. The spectrum of a star is as
the same library when the books are arranged on the shelves in
complete perfection and simplicity, so that he who looks may
appraise its contents at any or all points. Let us consider the
fundamental principles of spectroscopy.

1. When a solid body, a liquid, or a highly-condensed gas is
heated to incandescence, its light when passed through a
spectroscope forms a continuous spectrum: that is, a band of
light, red at one end and violet at the other, uninterrupted by
either dark or bright lines.

2. The light from the incandescent gas or vapor of a chemical
element, passed through a spectroscope, forms a bright-line
spectrum; that is, one consisting entirely of isolated bright
lines, distributed differently throughout the spectrum for the
different elements, or of bright lines superimposed upon a
relatively faint continuous spectrum.

3. If radiations from a continuous-spectrum source pass through
cooler gases or vapors before entering the spectroscope, a
dark-line spectrum results: that is, the positions which the
bright lines in the spectra of the vapors and gases would have
are occupied by dark or absorption lines. These are frequently
spoken of as Fraunhofer lines.

To illustrate: the gases and vapors forming the outer strata of
the Sun's atmosphere would in themselves produce bright-line
spectra of the elements involved. If these gases and vapors
could in effect be removed, without changing underlying
conditions, the remaining condensed body of the Sun should have
a continuous spectrum. The cooler overlying gases and vapors
absorb those radiations from the deeper and hotter sources
which the gases and vapors would themselves emit, and thus form
the dark-line spectrum of the Sun. The stretches of spectrum
between the dark lines are of course continuous-spectrum
radiations.

These principles are illustrated in Fig. 12. The essential
parts of a spectroscope are the slit--an opening perhaps
1/100th of an inch wide and 1/10th of an inch long--to admit
the light properly; a lens to render the light rays parallel
before they fall upon the prism or grating; a prism or grating;
a lens to receive the rays after they have been dispersed by
the prism or grating and to form an image of the spectrum a
short distance in front of the eye, where the eye will see the
spectrum or a sensitive dry-plate will photograph it. If we
place an alcohol lamp immediately in front of the slit and
sprinkle some common salt in the flame the two orange bright
lines of sodium will be seen in the eyepiece, close together,
as in the upper of the two spectra in the illustration. If we
sprinkle thallium salt in the flame the green line of that
element will be visible in the spectrum. If we take the lamp
away and place a lime light or a piece of white-hot iron in
front of the slit we shall get a brilliant continuous spectrum
not crossed by any lines, either bright or dark. Insert now the
alcohol-sodium-thallium lamp between the lime light and the
slit, and the observer will see the two sodium lines and one
thallium line in the same places as before, but as dark lines
on a background of bright continuous spectrum, as: illustrated
in the lower of the two spectra. Let us insert a screen between
the lamp and the lime light so as to cut out the latter, and we
shall see the bright lines of sodium and thallium reappear as
in the upper of the two spectra. These simple facts illustrate
Kirchhoff's immortal discovery of certain fundamental
principles of spectroscopy, in 1859. The gases and vapors in
the lamp flame are at a lower temperature than the lime source.
The cooler vapors of sodium and thallium have the power of
absorbing exactly those rays from the hotter lime or other
similar source which the vapors by themselves would emit to
form bright lines.

When we apply the spectroscope to celestial objects we find
apparently an endless variety of spectra. We shall illustrate
some of the leading characteristics of these spectra as in
Figs. 13 to 18, inclusive, and Figs. 21, 22, 23 and 24. The
spectra of some nebulae consist almost exclusively of isolated
bright lines, indicating that these bodies consist of luminous
gases, as Huggins determined in 1864; but a very faint
continuous band of light frequently forms a background for the
brilliant bright lines. Many of the nebular lines are due to
hydrogen, others are due to helium; but the majority, including
the two on the extreme right in Fig. 13, which we attribute to
the hypothetical element nebulium, and the close pair on the
extreme left, have not been matched in our laboratories and,
therefore, are of unknown origin. Most of the irregular nebulae
whose spectra have been observed, the ring nebulae, the
planetary and stellar nebulae, have very similar spectra,
though with many differences in the details.[1]

[1] My colleague, Wright, who has been making a study of the
nebular spectra, has determined the accurate positions of about
67 bright nebular lines.



The great spiral nebula in Andromeda has a continuous spectrum
crossed by a multitude of absorption lines. The spectrum is a
very close approach to the spectrum of our Sun. It is clear
that this spiral nebula is widely different from the
bright-line or gaseous nebulae in physical condition. The
spiral may be a great cluster of stars which are approximate
duplicates of our Sun, or there is a chance that it consists,
as Slipher has suggested, of a great central sun, or group of
suns, and of a multitude of small bodies or particles, such as
meteoric matter, revolving around the nucleus; this finely
divided matter being visible by reflected light which
originates in the center of the system.

There is an occasional star, like chi Carinae, whose spectrum
consists almost wholly of bright lines, in general bearing no
apparent relationship to the bright lines in the spectra of the
gaseous nebulae except that the hydrogen lines are there, as
they are almost everywhere. There is reason to believe that
such a spectrum indicates the existence of a very extensive and
very hot atmosphere surrounding the main body, or core, of the
star in question. This particular star is remarkable in that it
has undergone great changes in brilliancy and is located upon a
background of nebulosity. The chances are strong that the star
has rushed through the nebulosity with high rate of speed and
that the resulting bombardment of the star has expanded and
intensely heated its atmosphere.

There are the Wolf-Rayet stars, named from the French
astronomers who discovered the first three of this class, whose
spectra show a great variety of combinations of continuous
spectrum and bright bands. We believe that the continuous
spectrum in such a star comes from the more condensed central
part, or core, and that the bright-line light proceeds from a
hot atmosphere extending far out from the core.

The great majority of the stars have spectra which are
continuous, except for the presence of dark or absorption
lines: a few lines in the very blue stars, and an increasing
number of lines as we pass from the blue through the yellow and
red stars to those which are extremely red.

Secchi in the late 60's classified the spectra of the brighter
stars, according to the absorption lines in their spectra, into
Types I, II III and IV, which correspond: Type I, to the very
blue stars, such as Spica and Sirius; Type II, to the yellow
stars similar to our Sun; Type III, to the red stars such as
Aldebaran; and Type IV, to the extremely red stars, of which
the brightest representatives are near the limit of naked-eye
vision. Secchi knew little or nothing concerning stars whose
spectra contain bright lines, except as to the isolated
bright-line spectra of a few nebulae, and as to the bright
hydrogen lines in gamma Cassiopeia, and his system did not
include these.

One of the most comprehensive investigations ever undertaken by
a single institution was that of classifying the stars as to
their spectra, over the entire sky, substantially down to and
including the stars of eighth magnitude, by the Harvard College
Observatory, as a memorial to the lamented Henry Draper.
Professor Pickering and his associates have formulated a
classification system which is now in universal use. It starts
with the bright-line nebulae, passes to the bright-line stars,
and then to the stars in which the helium absorption lines are
prominent. The latter are called the helium stars, or
technically the Class B stars. The next main division includes
the stars in which hydrogen absorption is prominent, called
Class A. Classes B and A are blue stars. Then follows in
succession Class F, composed of bluish-yellow stars, which is
in a sense a transition class between the hydrogen stars and
those resembling our Sun, the latter called Class G. The Class
G stars are yellow. Class K stars are the yellowish-red; Class
M, the red; and Class N, the extremely red. Each of these
classes has several subdivisions which make the transition from
one main class to the next main class fairly gradual, and not
per saltum; though it should be said that the relationship of
Class N to Class M spectra is not clear. The illustration, Fig.
17, brings out the principal features of the spectra of Classes
B to M. The spectrum becomes more complicated as we pass from
Class B to the Class M, and the color changes from blue to
extreme red, because the violet and blue radiations become
rapidly weaker as we pass through the various classes.

GENERAL COURSE OF EVOLUTIONARY PROCESS

The general course of the evolutionary processes as applied to
the principal classes of celestial bodies is thought to be
fairly well known. With very few exceptions astronomers are
agreed as to the main trend of this order, but this must not be
interpreted to mean that there are no outstanding differences
of opinion. There are, in fact, some items of knowledge which
seem to run counter to every order of evolution that has been
proposed.

The large irregular nebulae, such as the great nebula in Orion,
the Trifid nebula, and the background of nebulosity which
embraces a large part of the constellation of Orion, are
thought to represent the earliest form of inorganic life known
to us. The material appears to be in a chaotic state. There is
no suggestion of order or system. The spectroscope shows that
in many cases the substance consists of glowing gases or
vapors; but whether they are glowing from the incandescence
resulting from high temperature, or electrical condition, or
otherwise, is unknown, though heat origin of their light is the
simplest hypothesis now available. Whether such nebulae are
originally hot or cold, we must believe that they are endowed
with gravitational power, and that their molecules or particles
are, or will ultimately be, in motion. It will happen that
there are regions of greater density, or nuclei, here and there
throughout the structure which will act as centers of
condensation, drawing surrounding materials into combination
with them. The processes of growth from nuclei originally small
to volumes and masses ultimately stupendous must be slow at
first, relatively more rapid after the masses have grown to
moderate dimensions and the supplies of outlying materials are
still plentiful, and again slow after the supplies shall have
been largely exhausted. By virtue of motions prevailing within
the original nebular structure, or because of inrushing
materials which strike the central masses, not centrally but
obliquely, low rotations of the condensed nebulous masses will
occur. Stupendous quantities of heat will be generated in the
building-up process. This heat will radiate rapidly into space
because the gaseous masses are highly rarefied and their
radiating surfaces are large in proportion to the masses. With
loss of heat the nebulous masses will contract in volume and
gradually assume forms more and more spherical. When the forms
become approximately spherical, the first stage of stellar life
may be said to have been reached.

It was Herschel's belief that by processes of condensation,
following the loss of heat by radiation into surrounding space,
formless nebulae gravitated into nebula of smaller and smaller
volumes until finally the planetary form was reached, and that
planetaries were the ancestors of stars in general. That the
planetaries do develop into stars, we have every reason to
believe; but that all nebulae, or relatively many nebulae, pass
through the planetary stage, or that many of our stars have
developed from planetaries, we shall later find good reason for
doubting. The probabilities are immensely stronger that the
stars in general have been formed directly from the irregular
nebulae, without the intervention of the planetaries. The
planetary nebula seem to be exceptional cases, but to this
point we shall return later.

It is quite possible, and even probable, that gaseous masses
have not in all cases passed directly to the stellar state. The
materials in a gaseous nebula may be so highly attenuated, or
be distributed so irregularly throughout a vast volume of
space, that they will condense into solids, small meteoric
particles for example, before they combine to form stars. Such
masses or clouds of non-shining or invisible matter are thought
to exist in considerable profusion within the stellar system.
The nebulosity connected more or less closely with the brighter
Pleiades stars may be a case in illustration. Slipher has
recently found that the spectra of two small regions observed
in this nebula are continuous, with absorption lines of
hydrogen and helium. This spectrum is apparently the same as
that of the bright Pleiades stars. Slipher's interpretation is
that the nebula is not shining by its own light, but is
reflecting to us the light of the Pleiades stars. That this
material will eventually be drawn into the stars already
existing in the neighborhood, or be condensed into new centers
and form other stars, we can scarcely doubt. The condensation
of such materials to form stars large enough to be seen from
the great distance of the Pleiades cluster must generate heat
in the process, and cause these stars in their earliest youth
to be substantially as hot as other stars formed directly from
gaseous materials. It is possible, also, that the spiral
nebulae will develop into stars, perhaps each such object into
many, or some of the larger ones into multitudes, of stars.

Let us attempt to visualize the conditions which we think exist
in a newly-formed star of average mass. It should be
essentially spherical, with surface fairly sharply defined. Our
Sun has average specific gravity of 1.4, as compared with that
of water. The average density of the very young star must
certainly be vastly lower; perhaps no greater than the density
of our atmosphere at the Earth's surface; it may even be
considerably lower than this estimate. The diameter of our Sun
is 1,400,000 kilometers. The diameter of the average young star
may be ten or twenty or forty times as great. The central
volume or core of the star is undoubtedly a great deal denser
than the surface strata, on account of pressure due to the
star's own gravitational forces. The conditions in the outer
strata should bear some resemblance to those existing in the
gaseous nebula. The star may or may not have a corona closely
or remotely similar to our Sun's corona. The deep interior of
the star must be very hot, though not nearly so hot as the
interiors of older stars; but the surface strata of the young
star should be remarkably hot; for, being composed of highly
attenuated gases, any lowering of the temperature by radiation
into surrounding space will be compensated promptly through the
medium of highly-heated convection currents which can travel
more rapidly from the interior to the surface than in the case
of stars in middle or old age. Even though the star, as
observed in our most powerful telescopes, is a point of light,
without apparent diameter, its outer strata should supply some
bright lines in the spectrum, because these strata project out
beyond what we may call the core of the star and themselves act
as sources of light. The spectrum should, therefore, consist of
some of the bright lines which were observed in the nebular
spectrum, these proceeding from the outer strata of the star;
and of a continuous spectrum made up of radiations proceeding
from the deeper strata or core of the star, in which a few dark
lines may be introduced by the absorption from those parts of
the outer gaseous strata which lie between us and the core.

A few hundred stellar spectra resembling this description are
well known, discovered mostly at the Harvard Observatory. Their
details differ greatly, but they have certain features in
common. The bright lines of helium are extremely rare in stars,
but they have been observed in a few stellar spectra. The
bright lines of nebulium have never been observed in a true
star: they and the radiations in the ultra-violet known as at
3726A, seem to be confined to the nebular state; and the
absorption lines of nebulium have never been observed in any
spectrum. As soon as the stellar state is reached nebulium is
no longer in evidence. Stellar spectra containing bright lines
seem always to include hydrogen bright lines. This is as we
should expect; hydrogen is the lightest known gas, and it is
probably the substance which can best exist in the outer strata
of stars in general. The extensive outer strata of very young
stars seem to be composed largely of hydrogen, though other
elements are in some cases present, as indicated by the weaker
bright lines in a few cases. This preference of hydrogen for
the outermost strata is illustrated by several very interesting
observations of the nebulae. The nebulium lines are relatively
strong in the central denser parts of the Orion and Trifid
nebulae, but the hydrogen bright-lines are relatively very
strong in the faint outlying parts of these nebulae. The
planetary nebula B.D.--12 degrees.1172 is seen in the ordinary
telescope to consist of a circular disc (probably a sphere or
spheroid) of light and a faint star in its center. When this
nebula is observed with a slitless spectrograph the hydrogen
and nebulium components are seen as circular discs, but the
hydrogen discs are larger than the nebulium discs. In other
words, the hydrogen forms an atmosphere about the central star
which extends out into space in all directions a great deal
farther than the nebulium discs extend. The Wolf-Rayet
star-planetary nebula D. M. + 30 degrees.3639 looks hazy in a
powerful telescope, and when examined in a spectroscope the
haziness is seen to be due to a sharply defined globe of
hydrogen 5 seconds of arc in diameter surrounding the star in
its center. Wolf and Burns have shown that in the Ring Nebula
in Lyra the 3726A and the hydrogen images are larger as to
outer diameter than the nebulium images, but that the latter
are the more condensed on the inner edge of the ring. Wright
has in the present year examined these and other nebulae with
special reference to the distribution of the principal
ingredients. He finds in general that the radiations at 4363A
and 4686A, of unknown or possibly helium origin, are most
closely compressed around the central nuclei of nebulae; that
the matter definitely known to be helium is more extended in
size; that the nebulium structure is still larger; and that the
hydrogen uniformly extends out farther than the nebulium; and
that the ultra violet radiation at 3726A seems to proceed from
the largest volume of all. The 37726A line, like the nebulium
line, is unknown in stellar spectra; it seems also to be
confined to true nebulosity. Neglecting the elements which have
never been observed in true stars, we may say that all these
observations are in harmony with the view that hydrogen should
be and is the principal element in the outer stratum of the
very young star. A few of the stars whose spectra contain
bright hydrogen lines have also a number of bright lines whose
chemical origin is not known. They appear to exist exactly at
this state of stellar life: several of them have not been found
in the spectra of the gaseous nebulae, and they are not
represented in the later types of stellar spectra. The strata
which produce these bright lines are thought to be a little
deeper in the stars than the outer hydrogen stratum.

A slightly older stage of stellar existence is indicated by the
type of spectrum in which some of the lines of hydrogen, always
those at the violet end, are dark, and the remaining hydrogen
lines, always those toward the red end, are bright. The
brightest star in the Pleiades group, Alcyone, presents
apparently the last of this series, for all of the hydrogen
lines are dark except H alpha, in the red. In some of the
bright-line stars which we have described, technically known as
Oe5, Harvard College Observatory found that the dark helium and
hydrogen lines exist, and apparently increase in intensity, on
the average, as the bright lines become fainter. Wright has
observed the absorption lines of helium and hydrogen in the
spectra of the nuclei of some planetary nebulae, although the
helium and hydrogen lines are bright in the nebulosity
surrounding the nuclei. We may say that when all of the bright
lines have disappeared from the spectra of stars, the helium
lines, and likewise the hydrogen lines, have in general become
fairly conspicuous. These stars are known as the helium stars,
or stars of Class B. Proceeding through the subdivisions of
Class B, the helium lines increase to a maximum of intensity
and then decrease. The dark hydrogen lines are more and more in
evidence, with intensities increasing slowly. In the middle and
later subdivisions of the helium stars silicon, oxygen and
nitrogen are usually represented by a few absorption lines.

Just as the gaseous nebulae radiate heat into space and
condense, so must the stars, with this difference: the nebulae
are highly rarified bodies, with surfaces enormously large in
proportion to the heat contents; and the radiation from them
must be relatively rapid. In fact, some of the nebulae seem to
be so highly rarified that radiation may take place from their
interiors almost as well as from their surfaces. The radiation
from a star just formed must occur at a much slower rate. The
continued condensation of the star, following the loss of heat,
must lead to a change of physical condition, which will be
apparent in the spectrum. It should pass from the so-called
helium group, to the hydrogen, or Class A group, not suddenly
but by insensible gradations of spectrum. In the Class A stars
the hydrogen lines are the most prominent features. The helium
lines have disappeared, except in a few stars where faint
helium remnants are in evidence. The magnesium lines have
become prominent and the calcium lines are growing rapidly in
strength. The so-called metallic lines, usually beginning with
iron and titanium lines, which have a few extremely faint
representatives in the last of the helium stars, become visible
here and there in the Class A spectra, but they are not
conspicuous.

In the next main division, the Class F spectra, the metallic
lines increase rapidly in prominence, and the hydrogen lines
decrease slightly in strength. These stars are not so blue as
the helium and hydrogen stars. They are intermediate between
the blue stars and the yellow stars, which begin with the next
class, G, of which our Sun is a representative.

The metallic lines are in Class G spectra in great number and
intensity, and the hydrogen lines are greatly reduced in
prominence. The calcium bands are very wide and intense.

Another step brings us to the very yellow and the
slightly-reddish stars, known as Class K. These stars are weak
in violet light, the hydrogen lines are substantially of the
same intensity as the most prominent metallic lines, and the
metallic lines are more and more in evidence.

Stars in the last subdivisions of the Class K and all of the
Class M stars are decidedly red. In these the hydrogen lines
are still further weakened and the metallic lines are even more
prominent. Their spectra are further marked by absorption bands
of titanium oxide, which reach their maximum strength in the
later subdivisions of Class M.

The extremely red stars compose Class N on the Harvard scale.
Their spectra are almost totally lacking in violet light, the
metallic absorption is very strong, and there are conspicuous
absorption bands of carbon.

Deep absorbing strata of titanium and carbon oxides seem to
exist in the atmospheres of the Class M and N stars,
respectively. The presence of these oxides indicates a
relatively low temperature, and this is what we should expect
from stars so far advanced in life.

The period of existence succeeding the very red stars has
illustrations near at hand, we think, in Jupiter, Saturn,
Uranus and Neptune, and in the Earth and the other small
planets and the Moon: bodies which still contain much heat, but
which are invisible save by means of reflected light.

The progression of stellar development, which we have
described, has been based upon the radiation of heat. This is
necessarily gradual, and the corresponding changes of spectrum
should likewise be gradual and continuous. It is not intended
to give the impression that only a few types of spectra are in
evidence: the variety is very great. The labels, Class B, Class
A, and so on to Class N, are intended to mark the miles in the
evolutionary journey. The Harvard experts have put up other
labels to mark the tenths of miles, so to speak, and some day
we shall expect to see the hundredths labeled. Further, it is
not here proposed that heat radiation is the only vital factor
in the processes of evolution. The mass of a star may be an
important item, and the electrical conditions may be concerned.
A very small star and a very massive star may develop
differently, and it is conceivable that there may be actual
differences of composition. But heat-radiation is doubtless the
most important factor.

The evolutionary processes must proceed with extreme
deliberation. The radiation of the heat actually present at any
moment in a large helium star would probably not require many
tens of thousands of years, but this quantity of heat is
negligible in comparison with the quantity generated within the
star during and by the processes of condensation from the
helium age down to the Class M state. We know that the
compression of any body against resistance generates or
releases heat. Now a gaseous star at any instant is in a state
of equilibrium. Its internal heat and the centrifugal force due
to its rotation about an axis are trying to expand it. Its own
gravitational power is trying to draw all of its materials to
the center. Until there is a loss of heat no contraction can
occur; but just as soon as there is such a loss gravity
proceeds to diminish the stellar volume. Contraction will
proceed more slowly than we should at first thought expect,
because in the process of contraction additional heat is
generated and this becomes a factor in resisting further
compression. Contraction is resisted vastly more by the heat
generated in the process of contraction than it is by the store
of heat already in evidence. The quantity of heat in our Sun,
now existing as heat, would suffice to maintain its present
rate of outflow only a few thousands of years. The heat
generated in the process of the Sun's shrinkage under gravity,
however, is so extensive as to maintain the supply during
millions of years to come. Helmholtz has shown that the
reduction of the Sun's radius at the rate of 45 meters per year
would generate as much heat within the Sun as is now radiated.
This rate of shrinkage is so slow that our most refined
instruments could not detect a change in the solar diameter
until after the lapse of 4,000 or 5,000 years. Again, there are
reasons for suspecting that the processes of evolution in our
Sun, and in other stars as well, may be enormously prolonged
through the influence of energy within the atoms or molecules
of matter composing them. The subatomic forces residing in the
radioactive elements represent the most condensed form of
energy of which we have any conception. It is believed that the
subatomic energy in a mass of radium is at least a million-fold
greater than the energy represented in the combustion or other
chemical transformation of any ordinary substance having the
same mass. These radioactive forces are released with extreme
slowness, in the form of heat or the equivalent; and if these
substances exist moderately in the Sun and stars, as they do in
the Earth, they may well be important factors in prolonging the
lives of these bodies.

Speaking somewhat loosely, I think we may say that the
processes of evolution from an extended nebula to a condensed
nebula and from the latter to a spherical star, are
comparatively rapid, perhaps normally confined to a few tens of
millions of years; but that the further we proceed in the
development process, from the blue star to the yellow, and
possibly but not certainly on to the red star, the slower is
the progress made, for the radiating surface through which all
the energy from the interior must pass becomes smaller and
smaller in proportion to the mass, and the convection currents
which carry heat from the interior to the surface must slow
down in speed.



A HISTORY OF FIJI.

BY DR. ALFRED GOLDSBOROUGH MAYER

IV

THE Fijians had a well-organized social system which recognized
six classes of society. (1) Kings and queens (Tuis and Andis).
(2) Chiefs of districts (Rokos). (3) Chiefs of villages,
priests (Betes), and land owners (Mata-ni-vanuas). (4)
Distinguished warriors of low birth, chiefs of the carpenter
caste (Rokolas), and chiefs of the turtle fishermen. (5) Common
people (Kai-si). (6) Slaves taken in battle.

The high chiefs still inspire great respect, and indeed it has
been the policy of the British government to maintain a large
measure of their former authority. Thus of the 17 provinces
into which the group was divided, 11 are governed by high
chiefs entitled Roko Tui, and there are about 176 inferior
chiefs who are the head men of districts, and 31 native
magistrates. In so far as may be consistent with order and
civilization these chiefs are permitted to govern in the old
paternal manner, and they are veritably patriarchs of their
people. The district chiefs are still elected by the land
owners, mata-ni-vanuas, by a showing of hands as of old.

Independent of respect paid to those in authority, rank is
still reverenced in Fiji. Once acting under the kind permission
and advice of our generous friend Mr. Allardyce, the colonial
secretary, and accompanied by my ship-mates Drs. Charles H.
Townsend, and H. F. Moore, I went upon a journey of some days
into the interior of Viti Levu, our guide and companion being
Ratu Pope Seniloli, a grandson of king Thakombau, and one of
the high chiefs of Mbau. Upon meeting Ratu Pope every native
dropped his burdens, stepped to the side of the wood-path and
crouched down, softly chanting the words of the tame, muduo!
wo! No one ever stepped upon his shadow, and if desirous of
crossing his path they passed in front, never behind him. Clubs
were lowered in his presence, and no man stood fully erect when
he was near. The very language addressed to high chiefs is
different from that used in conversation between ordinary men,
these customs being such that the inferior places himself in a
defenceless position with respect to his superior.

It is a chief's privilege to demand service from his subjects;
which was fortunate for us, for when we started down the
Waidina River from Nabukaluka our canoes were so small and
overloaded that the ripples were constantly lapping in over the
gunwale, threatening momentarily to swamp us. Soon, however, we
came upon a party of natives in a fine large canoe, and after
receiving their tama Ratu Pope demanded: "Where are you going"?
The men, who seemed somewhat awestricken, answered that it had
been their intention to travel up the river. Whereupon Ratu
Pope told them that this they might do, but we would take their
canoe and permit them to continue in ours. To this they acceded
with the utmost cheerfulness, although our noble guide would
neither heed our protests nor permit us to reward them for
their service, saying simply, "I am a chief. You may if you
choose pay me." In this manner we continued to improve our
situation by "exchanging" with every canoe we met which
happened to be better than our own, until finally our princely
friend ordered a gay party of merry-makers out of a fine large
skiff, which they cheerfully "exchanged" for our leaky canoes
and departed singing happily, feeling honored indeed that this
opportunity had come to them to serve the great chief Ratu Pope
Seniloli; and thus suffering qualms of conscience, we sailed to
our destination leaving a wake of confusion behind us. Moreover
I forgot to mention that many natives had by Ratu Pope's orders
been diverted from their intended paths and sent forward to
announce the coming of himself and the "American chiefs." Thus
does one of the Royal house of Mbau proceed through Fiji.

At first sight such behavior must appear autocratic, to say the
least, but it should be remembered that a high chief has it in
his power fully to recompense those about him, and this without
the payment of a penny. Indeed, many intelligent natives still
regret the introduction of money into their land, saying that
all the white man's selfishness had been developed through its
omnipotence. In Fiji to-day there are no poor, for such would
be fed and given a house by those who lived beside them. The
white man's callous brutality in ignoring the appeal of misery
is incomprehensible to the natives of Fiji. "Progress" they
have not in the sense that one man possesses vast wealth and
many around him struggle helplessly, doomed to life-long
poverty; nor have they ambition to toil beyond that occasional
employment required to satisfy immediate wants. Yet if life be
happy in proportion as the summation of its moments be
contented, the Fijians are far happier than we. Old men and
women rest beneath the shade of cocoa-palms and sing with the
youths and maidens, and the care-worn faces and bent bodies of
"civilization" are still unknown in Fiji. They still have
something we have lost and never can regain.

It is impossible to draw a line between personal service such
as was rendered to Ratu Pope and a regular tax (lala) for the
benefit of the entire community or the support of the communal
government; and the recognition of this fact actuated the
English to preserve much of the old system and to command the
payment of taxes in produce, rather than in money.

Land tenure in Fiji is a subject so complex that heavy volumes
might be written upon it. In general it may be said that the
chief can sell no land without the consent of his tribe.
Cultivated land belonged to the man who originally farmed it,
and is passed undivided to all his heirs. Waste land is held in
common. Native settlers who have been taken into the tribes
from time to time have been permitted to farm some of the waste
land, and for this privilege they and their heirs must pay a
yearly tribute to the chief either in produce or in service.
Thus this form of personal lala is simply rent. The whole
subject of land-ownership has given the poor English a world of
trouble, as one may see who cares to read the official reports
of the numerous intricate cases that have come before the
courts.

For example, one party based their claims to land on the
historic fact that their ancestors had eaten the chief of the
original owners, and the solemn British court allowed the
claim.

Basil Thomson in his interesting work upon "The Fijians; a
Study of the Decline of Custom," has given an authoritative
summary of the present status of taxation and land tenure, land
being registered under a modification of the Australian Torrens
system.

In order to protect these child-like people from the avarice of
our own race they are not permitted to sell their lands, and
the greater portion of the area of Fiji is still held by the
natives. The Hawaiian Islands now under our own rule furnish a
sad contrast, for here the natives are reduced by poverty to a
degraded state but little above that of peonage. The Fijians.
on the other hand, may not sell, but may with the consent of
the commissioner of native affairs lease their lands for a
period of not more than twenty years.

The Fijians appear never to have been wholly without a medium
of exchange, for sperm-whale's teeth have always had a
recognized purchasing power, but are more especially regarded
as a means of expressing good will and honesty of purpose. A
whale's tooth is as effective to secure compliance with the
terms of a bargain as an elaborately engraved bond would be
with us. More commonly, however, exchanges are direct, each man
bringing to the village green his taro, yaqona, yams or fish
and exchanging with his neighbors; the rare disputes being
settled by the village chief.

In traveling you will discover no hotels, but will be
entertained in the stranger's houses, and in return for your
host's hospitality you should make presents to the chief.
Indeed to journey in good fashion you should be accompanied by
a train of bearers carrying heavy bags full of purposed gifts,
and nowhere in the world is the "rate per mile" higher than in
Polynesia.

As in all communities, including our own world of finance, a
man's wealth consists not only in what he possesses but even
more so in the number of people from whom he can beg or borrow.
Wilkes records an interesting example of this, for he found
that the rifle and other costly presents he had presented to
King Tanoa were being seized upon by his (Tanoa's) nephew who
as his vasu had a right to take whatever he might select from
the king's possessions. Indeed, in order to keep his property
in sight, Tanoa was forced to give it to his own sons, thus
escaping the rapacity of his nephew. The construction of the
British law is such that a vasu who thus appropriates property
to himself could  be sued and forced to restore it, but not a
single Fijian has yet been so mean as to bring such a matter
into court.

An individual as such can hardly be said to own property, for
nearly all things belong to his family or clan, and are shared
among cousins. This condition is responsible for that absence
of personal ambition and that fatal contentment with existing
conditions, which strikes the white man as so illogical, but
which is nevertheless the dominant feature of the social fabric
of the Polynesians, and which has hitherto prevented the
introduction of "ideals of modern progress." The natives are
happy; why work when every reasonable want is already supplied?
None are rich in material things, but none are beggars
excepting in the sense that all are such. No one can be a
miser, a capitalist, a banker, or a "promoter" in such a
community, and thieves are almost unknown. Indeed, the honesty
of the Fijians is one of those virtues which has excited the
comment of travelers. Wilkes, who loathed them as "condor-eyed
savages," admits that the only thing which any native attempted
to steal from the Peacock was a hatchet, and upon being
detected the chief requested the privilege of taking the man
ashore in order that he might be roasted and eaten. Theft was
always severely punished by the chief; Maafu beating a thief
with the stout stalk of a cocoanut leaf until the culprit's
life was despaired of, and Tui Thakau wrapping one in a tightly
wound rope so that not a muscle could move while the wretch
remained exposed for an entire day to the heat of the sun.

During Professor Alexander Agassiz's cruises in which he
visited nearly every island of the Fijis, and the natives came
on board by hundreds, not a single object was stolen, although
things almost priceless in native estimation lay loosely upon
the deck. Once, indeed, when the deck was deserted by both
officers and crew and fully a hundred natives were on board, we
found a man who had been gazing wistfully for half an hour at a
bottle which lay upon the laboratory table. Somehow he had
managed to acquire a shilling, a large coin in Fiji, and this
he offered in exchange for the coveted bottle. One can never
forget his shout of joy and the radiance of his honest face as
he leaped into his canoe after having received it as a gift.

Even the great chief Ratu Epele of Mbau beamed with joy when
presented with a screw-capped glass tobacco jar, and Tui Thakau
of Somo somo had a veritable weakness for bottles and possessed
a large collection of these treasures.

Intelligent and well-educated natives who know whereof they
speak have told me that they desire not the white man's system,
entailing as it does untold privation and heart-burnings to the
many that the few may enjoy a surfeit of mere material things.
As the natives say, "The white man possesses more than we, but
his life is full of toil and sorrow, while our days are happy
as they pass."

Thus in the Pacific life is of to-day; the past is dead, and
the future when it comes will pass as to-day is passing. Life
is a dream, an evanescent thing, all but meaningless, and real
only as is the murmur of the surf when the sea-breeze comes in
the morning, and man awakens from the oblivion of night.

Hoarded wealth inspires no respect in the Pacific, and indeed,
were it discovered, its possession would justify immediate
confiscation. Yet man must raise idols to satisfy his instinct
to worship things above his acquisition, and thus rank is the
more reverenced because respect for property is low. Even
to-day there is something god-like in the presence of the high
chiefs, and none will cross the shadow of the king's house.
Even in war did a common man kill a chief he himself was killed
by men of his own tribe.

As it is with property so with relationships. The family ties
seem loosened; every child has two sets of parents, the adopted
and the real, and relationships founded upon adoption are more
respected than the real. Rank descends mainly through the
mother. The son of a high chief by a common woman is a low
chief, or even a commoner, but the son of a chieftainess by a
common man is a chief. Curiously, there are no words in Fijian
which are the exact equivalent of widow and widower. In the
Marshall group the chief is actually the husband of all the
women of his tribe, and as Lorimer Fison has said in his "Tales
from Old Fiji," their designation and understanding of
relationships suggests that there was once a time when "all the
women were the wives of every man, and all the men were the
husbands of every woman," as indeed was almost the case in
Tahiti at the time of Captain Cook's visit to this island.

The social customs of Fiji are rarely peculiar to Fiji itself,
but commonly show their relationship or identity with those of
the Polynesians or Papuans. Curiously indeed, while the
original stock of the Fijians was probably pure Papuan, their
social and economic systems are now dominated by Polynesian
ideas, and only among the mountain tribes do we find a clear
expression of the crude Papuan systems of life and thought.
This in itself shows that under stimulation the Fijians are
capable of advancement in cultural ideals.

This superposition of a Polynesian admixture upon a barbarous
negroid stock may account for the anomalous character of the
Fijians, for in the arts they equalled or in some things
excelled the other island peoples of the Pacific, and some of
their customs approached closely to the cultural level of the
Polynesians, but in certain fundamental things they remained
the most fiendish savages upon earth. Indeed we should expect
that contact with a somewhat high culture would introduce new
wants, and thus affect their arts more profoundly than their
customs.

In common with all primitive peoples, their names of men and
women are descriptive of some peculiarity or circumstance
associated with the person named. Indeed, names were often
changed after important events in a person's life, thus our old
friend Thakombau began life as Seru, then after the coup d'etat
in which he slaughtered his father's enemies and reestablished
Tanoa's rule in Mbau he was called Thakombau (evil to Mbau). At
the time he also received another name Thikinovu (centipede) in
allusion to his stealthiness in approaching to bite his enemy,
but this designation, together with his "missionary" name
"Ebenezer," did not survive the test of usage. Miss Gordon
Cumming gives an interesting list of Fijian names translated
into English. For women they were such as Spray of the Coral
Reef, Queen of Parrot's Land, Queen of Strangers, Smooth Water,
Wife of the Morning Star, Mother of Her Grandchildren, Ten
Whale's Teeth, Mother of Cockroaches, Lady Nettle, Drinker of
Blood, Waited For, Rose of Rewa, Lady Thakombau, Lady Flag,
etc. The men's names were such as The Stone (eternal) God,
Great Shark, Bad Earth, Bad Stranger, New Child, More Dead
Man's Flesh, Abode of Treachery, Not Quite Cooked, Die Out of
Doors, Empty Fire, Fire in the Bush, Eats Like a God, King of
Gluttony, Ill Cooked, Dead Man, Revenge, etc.

In the religion of a people we have the most reliable clue to
the history of their progress in culture and intelligence, for
religions even when unwritten are potent to conserve old
conceptions, and thus their followers advance beyond them, as
does the intelligence of the twentieth century look pityingly
upon the conception of the cruel and jealous God of the Old
Testament, whose praises are nevertheless still sung in every
Christian church. Thus in Tahiti the people were not cannibals,
but the gods still appeared in the forms of birds that fed upon
the bodies of the sacrificed. The eye of the victim was,
indeed, offered to the chief, who raised it to his lips but did
not eat it. In Samoa also where the practice of cannabalism was
very rare and indulged in only under great provocation, some of
the gods remained cannibals, and the surest way of appeasing
any god was to be laid upon the stones of a cold oven. In
Tahiti and Samoa, while most of the gods were malevolent, a few
were kindly disposed towards mortals; in Fiji, however, they
were all dreaded as the most powerful, sordid, cruel and
vicious cannibal ghosts that have ever been conjured into being
in the realm of thought.

All over the Pacific from New Zealand to Japan, and from New
Guinea to Hawaii, ancestor-worship forms the backbone of every
religion as clearly as it did in Greece or Rome. There are
everywhere one or more very ancient gods who may always have
existed and from whom all others are descended. Next in order
of reverence, although not always in power, come their
children, and finally the much more numerous grandchildren and
remote descendants of these oldest and highest gods. Finally,
after many generations, men of chieftain's rank were born to
the gods. Thus a common man could never attain the rank of a
high chief, for such were the descendants of the gods, while
commoners were created out of other clay and designed to be
servants to the chiefs.

But the process of god-making did not end with the appearance
of men, for great chiefs and warriors after death became kalou
yalo, or spirits, and often remained upon earth a menace to the
unwary who might offend them. Curiously, these deified mortals
might suffer a second death which would result in their utter
annihilation, and while in Fiji we heard a tale of an old chief
who had met with the ghost of his dead enemy and had killed him
for the second and last time; the club which served in this
miraculous victory having been hung up in the Mbure as an
object of veneration.

Of a still lower order were the ghosts of common men or of
animals, and most dreaded of all was the vengeful spirit of the
man who had been devoured. The ghosts of savage Fiji appear all
to have been malevolent and fearful beings, whereas those of
the more cultured Polynesians were some of them benevolent. As
Ellis says of the Tahitian mythology:

Each lovely island was made a sort of fairyland and the spells
of enchantment were thrown over its varied scenes. The
sentiment of the poet that

         "Millions of spiritual creatures walk the earth,
   Unseen, both when we wake, and when we sleep"

was one familiar to their minds, and it is impossible not to
feel interested in a people who were accustomed to consider
themselves surrounded by invisible intelligences, anti who
recognized in the rising sun, the mild and silver moon, the
shooting star, the meteor's transient flame, the ocean's roar,
the tempest's blast, or the evening breeze the movements of
mighty spirits.

The gods and ghosts of Fiji often entered into the bodies of
animals or men, especially idiots.

Thus when the Carnegie Institution Expedition arrived at the
Murray Islands in Torres Straits, the scientific staff were
much pleased at the decided evidences of respect shown by the
natives until it came out that the Islanders considered their
white guests to be semi-idiots, and hence powerful sorcerers to
be placated. Fijian religion had developed into the oracular
stage, and the priest after receiving prayers and offerings
would on occasions be entered into by the god. Tremors would
overspread his body, the flesh of which would creep horribly.
His veins would swell, his eyeballs protrude with excitement
and his voice, becoming quavering and unnatural, would whine
out strange words, words spoken by the god himself and unknown
to the priest who as his unconscious agent was overcome by
violent convulsions. Slowly the contortions grew less and with
a start the priest would awaken, dash his club upon the ground
and the god would leave him. It may well be imagined that the
priests were the most powerful agents of the chiefs in
forwarding the interests of their masters, for, as in ancient
Greece or Rome, nothing of importance was undertaken without
first consulting the oracle.

Surrounded by multitudes of demons, ghosts, and genii who were
personified in everything about him, religion was the most
powerful factor in controlling Fijian life and politics. In
fact, it entered deeply into every act the native performed.
The gods were more monstrous in every way than man, but in all
attributes only the exaggerated counterparts of Fijian chiefs.

War was constantly occurring among these gods and spirits, and
even high gods could die by accident or be killed by those of
equal rank so that at least one god, Samu, was thus dropped out
of the mythology in 1847.

Ndengei was the oldest and greatest, but not the most
universally reverenced god. He lived in a cavern in the
northeastern end of Viti Levu, and usually appeared as a snake,
or as a snake's head with a body of stone symbolizing eternal
life. Among the sons and grandsons of Ndengei were Roko
Mbati-ndua, the one-toothed lord; a fiend with a huge tooth
projecting from his lower jaw and curving over the top of his
head. He had bat's wings armed with claws and was usually
regarded as a harbinger of pestilence. The mechanic's god was
eight-handed, gluttony had eighty stomachs, wisdom possessed
eight eyes. Other gods were the adulterer, the abductor of
women of rank and beauty, the rioter, the brain-eater, the
killer of men, the slaughter god, the god of leprosy, the
giant, the spitter of miracles, the gods of fishermen and of
carpenters, etc. One god hated mosquitoes and drove them away
from the place where he lived. The names and stations of the
gods are described by Thomas Williams, who has given the most
detailed account of the old religion.

As with all peoples whose religion is barbarous, there were
ways of obtaining sanctuary and many a man has saved his life
by taking advantage of the tabus which secured their operation.
No matter how desirous your host might be of murdering you, as
long as you remained a guest under his roof you were safe,
although were you only a few yards away from his door he would
eagerly attack you.

But not only did the Fijians live in a world peopled by
witches, wizards, prophets, seers and fortune-tellers, but
there was a perfect army of fairies which overran the whole
land, and the myths concerning which would have filled volumes
could they ever have been gathered. The gnome-like spirits of
the mountains had peaked heads, and were of a vicious, impish
disposition, but were powerless to injure any one who carried a
fern leaf in his hand.

Sacred relics such as famous clubs, stones possessing
miraculous powers, etc., were sometimes kept in Fijian temples,
but there were no idols such as were prayed to by the
Polynesians.

The fearful alternatives of heaven and hell were unknown to the
Fijians. They believed in an eternal existence for men,
animals, and even canoes and other inanimate things, but the
future life held forth no prospect either of reward for virtues
or punishment for evil acts committed while alive. So certain
were they of a future life that they always referred to the
dead as "the absent ones," and their land of shades (Mbulu) was
not essentially different from the world they lived in. Indeed,
their chief idea of death was that of rest, for as William's
states, they have an adage: "Death is easy: Of what use is
life? To die is rest."

There were, however, certain precautions the Fijian felt it
advisable to take before entering the world to come. If he had
been so unfortunate as not to have killed a man, woman or
child, his duty would be the dismal one of pounding filth
throughout eternity, and disgraceful careers awaited those
whose ears were not bored or women who were not tatooed upon
parts covered by the liku. Moreover, should a wife not
accompany him (be strangled at the time of his death) his
condition would be the dismal one of a spirit without a cook.
Thirdly, as one was at the time of death so would the spirit be
in the next world. It was therefore an advantage to die young,
and people often preferred to be buried alive, or strangled,
than to survive into old age. Lastly and most important, one
must not die a bachelor, for such are invariably dashed to
pieces by Nangganangga, even if they should succeed in elud-
ing the grasp of the Great Woman, Lewa-levu, who flaunts the
path of the departed spirits and searches for the ghosts of
good-looking men. Let us imagine, however, that our shade
departs this life in the best of form, young, married, with the
lobes of his ears pierced, not dangerously handsome and a
slayer of at least one human being. He starts upon the long
journey to the Valhalla of Fiji. Soon he comes to a spiritual
Pandanus at which he must throw the ghost of the whale's tooth
which was placed in his hand at time of burial. If he succeeds
in hitting the Pandanus, he may then wait until the spirit of
his strangled wife comes to join him, after which he boards the
canoe of the Fijian Charon and proceeds to Nambanggatai, where
until 1847 there dwelt the god Samu, and after his death
Samuyalo "the killer of souls."

This god remains in ambush in some spiritual mangrove bushes
and thrusts a reed within the ground upon the path of the ghost
as a warning not to pass the spot. Should the ghost be brave he
raises his club in defiance, whereupon Samuyalo appears, club
in hand, and gives battle. If killed in this combat, the ghost
is cooked and eaten by the soul killer, and if wounded he must
wander forever among the mountains, but if the ghost be
victorious over the god he may pass on to be questioned by
Ndengei, who may consign him either to Mburotu, the highest
heaven, or drop him over a precipice into a somewhat inferior
but still tolerable abode, Murimuria. This Ndengei does in
accordance with the caprice of the moment and without reference
either to the virtues or the faults of the deceased. Thus of
those who die only a few can enter the higher heaven for the
Great Woman and the Soul destroyer overcome the greater number
of those who dare to face them. As for the victims of cannibal
feasts, their souls are devoured by the gods when their bodies
are eaten by man.

In temperament and ambitions the spirits of the dead remained
as they were upon earth, but of more monstrous growth in all
respects, resembling giants greater and more vicious than man.
War and cannibalism still prevailed in heaven, and the
character of the inhabitants seems to have been fiendish or
contemptible as on earth; for the spirits of women who were not
tattooed were unceasingly pursued by their more fortunate
sisters, who tore their bodies with sharp shells, often making
mince-meat of them for the gods to eat. Also the shade of any
one whose ears had not been pierced was condemned to carry a
masi log over his shoulder and submit to the eternal ridicule
of his fellow spirits.

Altogether, this religion seems to have been as sordid, brutal
and vicious as was the ancestral negroid stock of the Fijians.
Connected with it there was, however, a rude mythology, clumsy
but romantic, too much of which has been lost; for the natives
of to-day have largely forgotten its stories or are ashamed to
repeat it to the whites. In recent times the natives have
tended to make their folk-lore conform to Biblical stories, or
to adapt them to conditions of the present day. The interesting
subject of the lingering influence of old beliefs upon the life
of the natives of to-day has engaged the attention of Basil
Thomson in "The Fijians, a Study of the Decay of Custom."

As in every British colony, the people are taught to respect
the law. Sentences of imprisonment are meted out to natives for
personal offences which if committed by white men would be
punished by small fines, but the reason for this is that in the
old native days such acts were avenged by murder, and it is to
prevent crime that a prison term has been ordained. The natives
take their imprisonment precisely as boys in boarding school
regard a flogging, the victim commonly becoming quite a hero
and losing no caste among his fellows. Indeed it is a common
sight to see bands of from four to eight stalwart "convicts" a
mile or more from the prison marching unguarded through the
woods as they sing merrily on their way "home" to the jail.
Once I recall seeing two hundred prisoners, all armed with long
knives, engaged in cutting weeds along the roadside, chanting
happily as they slashed, while a solitary native dressed only
in a waist-cloth and armed only with a club stood guard at one
end of the line, and this not near the prison, but in a lonely
wood fully a mile from the nearest house.

In 1874, the British undertook the unique task of civilizing
without exploiting a barbarous and degraded race which was
drifting hopelessly into ruin. They began the solution of this
complex problem by arresting the entire race and immuring them
within the protecting walls of a system which recognized as its
cardinal principle that the natives were unfit to think or act
for themselves. For a generation the Fijians have been in a
prison wherein they have become the happiest and best behaved
captives upon earth. During this time they have become
reconciled to a life of peace, and have forgotten the taste of
human flesh; and while they cherish no love for the white man,
they feel the might of his law and know that his decrees are as
finalities of fate. All are serving life sentences to the white
man's will, and the fire of their old ambition has cooled into
the dull embers of resignation and then died into the apathy of
contentment with things that are. Worse still, they have grown
fond of their prison world, and the most pessimistic feature in
the Fijian situation of to-day is the evident fact that there
is almost no discontent among the natives. Old things have
withered and decayed, but new ambition has not been born.

It is in no spirit of criticism of British policy that I have
written the above paragraph for it was absolutely necessary
that the race should "calm down" for a generation at least
before it could be trusted to arise. Now, however, there are no
more old chiefs whose memories hark back to days of savagery,
and now for the first and only time has come the critical
period in the unique governmental experiment the British have
undertaken to perform, for now is the time when the child must
learn to walk alone and the support of guardian arms must in
kindness be withdrawn, else there must be nurtured but a
cripple, not a man.

Among the generation of to-day the light of a new ambition must
appear in Fiji or the race shall dwindle to its death. No real
progress has been made by the Fijians; they have received much
from their teachers, but have given nothing in return. They are
in the position of a youth whose schooling has just been
finished, life and action lie before him; will he awaken to his
responsibility, develop his latent talent, character and power,
and recompense his teachers by achievement, or will he sink
into the apathy of a vile content?

The situation in Fiji is one of peculiar delicacy for the
desire for better things must arise among the Fijians
themselves, and should it once appear, the paternalism of the
present government must be wisely withdrawn to permit of more
and more freedom in proportion as the natives may become
competent to think and act rightly for themselves. A cardinal
difficulty is the unfortunate fact that the natives DESIRE no
change, and even if individually discontented and ambitious,
they know of no profession, arts or trades to which they might
turn with hope of fortune. The establishment of manual training
schools wherein money-making trades should be taught, if
possible BY NATIVE teachers, is sorely needed in Fiji.

At present there is too little freedom of thought in Fiji; fear
of the chief and of Samuyalo's club has been replaced by fear
of the European and his hell. Free, fearless thought is the
father of high action, and while their minds remain steeped in
an apathy of dread there can be no soil in which the seed of
independence can germinate.

Yet it is still possible that the Fijians may attain
civilization. Of all the archipelagoes of Polynesia, Fiji alone
may still be called the "Isles of Hope." As one who has known
and grown to love these honest, hospitable, simple people, I
can only hope that the day is not far distant when a leader may
arise among them who will turn their faces toward the light of
a brighter sky, and their hands to a worthier task than has
ever yet been performed in Polynesia.

Yet why civilize them? Often does one ask oneself this
question, but the answer comes as the voice of fate, "they must
attain civilization or they must die." Should the population
continue to decline at its present rate, the time is imminent
when the dark-skinned men of Fiji will be not the natives, but
the swarming progeny of the coolies of Calcutta.

Nowhere over all the wide Pacific have the natives been more
wisely or unselfishly ruled than in Fiji, yet even here native
life seems to be growing less and less purposeful year by year.
In time it is hoped a reaction may set in and that with the
decline of communism new ambitions may replace the old, but
then will come the problem of the rich and the poor--a thing
unknown in Fijian life to-day.

Hardly the first lessons in civilization have been taught in
Polynesia, yet who can predict the noon day, should even the
faintest glow appear in native hope. In former ages the
Japanese were a barbarous insular people, and as in our own
civilization the traditions and habits of rude Aryan ancestors
still color our fundamental thoughts so in Japan we find
evidences of a culture essentially similar to that of the
Pacific Islands of to-day. The ancient ancestor worship of
Japan is strangely like that of the tropical Pacific with its
gods, the ghosts of long departed chiefs, and its high chief a
living god to-day. Moreover in the Pacific Islands the house
consists of but a single room, and such to-day is essentially
the case in Japan, save only that delicate paper screens divide
its originally unitary floor-space into temporary compartments.
As in the South Seas, matting still covers the floor of the
Japanese house, its roof is thatched, and is constructed before
the sides are made, there is no chimney, the fire-place is an
earthen space upon the floor or is sustained within an
artistically molded bronze brazier, the refined descendant of
the cruder hearth. In Polynesia as in Japan one seats oneself
anywhere in tailor-fashion upon the floor, and upon this floor
the meals are served, and here one sleeps at night, nor will
the women partake of food in the presence of the men. In
essential fundamental things of life the Japanese show their
kinship in custom and tradition to the insular peoples of
Asiatic origin now occupying the Pacific, and if Japan has
attained to so great a height in culture and civilization, why
may we not hope for better days for the South Sea Islanders?



WAR SELECTION IN THE ANCIENT WORLD

BY CHANCELLOR DAVID STARR JORDAN

LELAND STANFORD JUNIOR UNIVERSITY

"The human harvest was bad!" Thus the historian sums up the
conditions in Rome in the days of the good emperor, Marcus
Aurelius. By this he meant that while population and wealth
were increasing, manhood had failed. There were men enough in
the streets, men enough in the camps, menial laborers enough
and idlers enough, but of good soldiers there were too few. For
the business of the state, which in those days was mainly war,
its men were inadequate.

In recognition of this condition we touch again the
overshadowing fact in the history of Europe, the effect of
"military selection" on the human breed.

In rapid survey of the evidence brought from history one must
paint the picture, such as it is, with a broad brush, not
attempting to treat exceptions and qualifications, for which
this article has no space and concerning which records yield no
data. Such exceptions, if fully understood, would only prove
the rule. The evil effects of military selection and its
associated influences have long been recognized in theory by
certain students of social evolution. But the ideas derived
from the sane application of our knowledge of Darwinism to
history are even now just beginning to penetrate the current
literature of war and peace. In public affairs most nations
have followed the principle of opportunism, "striking while the
iron is hot," without regard to future results, whether of
financial exhaustion or of race impoverishment.

The recorded history of Rome begins with small and vigorous
tribes inhabiting the flanks of the Apennines and the valleys
down to the sea, and blending together to form the Roman
republic. They were men of courage and men of action, virile,
austere, severe and dominant.[1] They were men who "looked on
none as their superior and none as their inferior." For this
reason, Rome was long a republic. Free-born men control their
own destinies. "The fault," says Cassius, "is not in our stars,
but in ourselves that we are underlings." Thus in freedom, when
Rome was small without glory, without riches, without colonies
and without slaves, she laid the foundations of greatness.

[1] Virilis, austerus, severus, dominous, good old words
applied by Romans to themselves.



But little by little the spirit of freedom gave way to that of
domination. Conscious of power, men sought to exercise it, not
on themselves but on one another. Little by little this meant
aggression, suppression, plunder, struggle, glory and all that
goes with the pomp and circumstance of war. So the
individuality in the mass was lost in the aggrandizement of the
few. Independence was swallowed up in ambition and patriotism
came to have a new meaning, being transferred from hearth and
home to the camp and the army.

In the subsequent history of Rome, we have now to consider only
a single factor, the reversal of selection." In Rome's
conquests, Vir, the real man, went forth to battle and foreign
invasion; Homo, the human being, remained on the farm and in
the workshop and begat the new generations. "Vir gave place to
Homo," says the Latin author. Men of good stock were replaced
by the sons of slaves and camp-followers, the riff-raff of
those the army sucked in but could not use.

The Fall of Rome was due not to luxury, effeminacy or
corruption, not to Nero's or Caligula's wickedness, nor to the
futility of Constantine's descendants. It began at Philippi,
where the spirit of domination overcame the spirit of freedom.
It was forecast still earlier in the rise of consuls and
triumvirs incident to the thinning out of the sturdy and
self-sufficient strains who brooked no arbitrary rule. While
the best men were falling in war, civil or foreign, or remained
behind in faraway colonies, the stock at home went on repeating
its weakling parentage. A condition significant in Roman
history is marked by the gradual swelling of the mob, with the
rise in authority of the Emperor who was the mob's exponent.
Increase of arbitrary power went with the growing weakness of
the Romans themselves. Always the "Emperor" serves as a sort of
historical barometer by which to measure the abasement of the
people. The concentrated power of Julius Caesar, resting on his
own tremendous personality, showed that the days of Cincinnatus
and of Junius Brutus were past. The strength of Augustus rested
likewise in personality. The rising authority of later emperors
had its roots in the ineffectiveness of the mob, until it came
to pass that "the little finger of Constantine was thicker than
the loins of Augustus." This was due not to Constantine's
force, but to the continued reversal of selection among the
people over whom he ruled. The emperor, no longer the strong
man holding in check all lesser men and organizations, became
the creature of the mob; and "the mob, intoxicated with its own
work, worshipped him as divine." Doubtless the last emperor,
Augustulus Romulus, before the Goths threw him into the
scrap-heap of history, was regarded by the mob and himself as
the most god-like of the whole succession.

The Romans of the Republic might perhaps have made a history
very different. Had they held aloof from world-conquering
schemes Rome might have remained a republic, enduring even down
to our day. The seeds of Rome's fall lay not in race nor in
form of government, nor in wealth nor in senility, but in the
influences by which the best men were cut off from parenthood,
leaving its own weaker strains and strains of lower races to be
fathers of coming generations.

"The Roman Empire," says Professor Seely, "perished for want of
men." Even Julius Caesar notes the dire scarcity of men, while
at the same time there were people enough. The population
steadily grew; Rome was filling up like an overflowing marsh.
Men of a certain type were plenty, but self-reliant farmers,
"the hardy dwellers on the flanks of the Apennines," men of the
early Roman days, these were fast going, and with the change in
type of population came the turn in Roman history.

The mainspring of the Roman army for centuries has been the
patient strength and courage, capacity for enduring hardships,
instinctive submission to military discipline of the population
that lined the Apennines.

"The effect of the wars was that the ranks of the small farmers
were decimated, while the number of slaves who did not serve in
the army multiplied," says Professor Bury. Thus "Vir gave place
to Homo," thus the mob filled Rome and the mob-hero rose to the
imperial throne. No wonder that Constantine seemed greater than
Augustus. No wonder that "if Tiberius chastised his subjects
with whips, Valentinian chastised them with scorpions."[2]

[2] The point of this is that the cruel Tiberius was less
severe on the Romans of his day than was the relatively
benevolent Valentinian on his decadent people.



With Marcus Aurelius and the Antonines came a "period of
sterility and barrenness in human beings." Bounties were
offered for marriage. Penalties were devised against
race-suicide. "Marriage," says Metellus, "is a duty which,
however painful, every citizen ought manfully to discharge."
Wars were conducted in the face of a declining birth-rate, and
the decline in quality and quantity in the human breed engaged
very early the attention of Roman statesmen. Deficiencies of
numbers were made up by immigration, willing or enforced.
Failure in quality was beyond remedy.

Says Professor Zumpt:

'Government having assumed godhead, took at the same time the
appurtenances of it. Officials multiplied. Subjects lost their
rights. Abject fear paralyzed the people and those that ruled
were intoxicated with insolence and cruelty.... The worst
government is that which is most worshipped as divine. . . .
The emperor possessed in the army an overwhelming force over
which citizens had no influence, which was totally deaf to
reason or eloquence, which had no patriotism because it had no
country, which had no humanity because it had no domestic ties.
. . . There runs through Roman literature a brigand's and
barbarian's contempt for honest industry. . . . Roman
civilization was not a creative kind, it was military, that is,
destructive.'

What was the end of it all? The nation bred Romans no more. To
cultivate the Roman fields "whole tribes were borrowed." The
man with quick eye and strong arm gave place to the slave, the
scullion, the pariah, whose lot is fixed because in him there
lies no power to alter it. So at last the Roman world, devoid
of power to resist, was overwhelmed by the swarming Ostrogoths.

The barbarian settled and peopled the empire rather than
conquered it. It was the weakness of war-worn Rome that gave
the Germanic races their first opportunity.

"The nation is like a bee," wisely observes Bernard Shaw, "as
it stings it dies."

In his monumental history of the "Downfall of the Ancient
World" (Der Untergang der Antikenwelt) Dr. Otto Seeck of the
University of Munster in Westphalia, treats in detail the
causes of such decline. He first calls attention to the
intellectual stagnation which came over the Roman Empire about
the beginning of the Christian Era. This manifested itself in
all fields of intellectual activity. No new idea of any
importance was advanced in science nor in technical and
political studies. In the realm of literature and art also one
finds a complete lack of originality and a tendency to imitate
older models. All this Seeck asserts, was brought about by the
continuous "rooting out (Ausrottung) of the best"[3] through
war.

[3] "Die Ausrottung der Besten, die jenen schwacheren Volken
die Vernichtung brachte, hat die starken Germanen erst
befahigt, auf den Trummern der antiken Welt neue dauerende
Gemeinschaften zu errichten." Seeck.



Such extermination which took place in Greece as well as in
Rome, was due to persistent internal conflicts, the constant
murderous struggle going on between political parties, in
which, in rapid succession, first one and then the other was
victorious. The custom of the victors being to kill and banish
the leaders and all prominent men in the defeated party, often
destroying their children as well, it is evident that in time
every strain distinguished for moral courage, initiative or
intellectual strength was exterminated. By such a systematic
killing off of men of initiative and brains, the intellectual
level of a nation must necessarily be lowered more and more. In
Rome as in Greece observes Seeck:

'A wealth of force of spirit went down in the suicidal wars. .
. . In Rome, Marius and Cinna slew the aristocrats by hundreds
and thousands. Sulla destroyed the democrats, and not less
thoroughly. Whatever of strong blood survived, fell as an
offering to the proscription of the Triumvirate. . . . The
Romans had less of spontaneous force to lose than the Greeks.
Thus desolation came sooner to them. Whoever was bold enough to
rise politically in Rome was almost without exception thrown to
the ground. ONLY COWARDS REMAINED, AND FROM THEIR BLOOD CAME
FORWARD THE NEW GENERATIONS.[4] Cowardice showed itself in lack
of originality and in slavish following of masters and
traditions.'

[4] Author's italics.



Certain authors, following Varro, have maintained that Rome
died a "natural death," the normal result of old age. It is
mere fancy to suppose that nations have their birth, their
maturity and their decline under an inexorable law like that
which determines the life history of the individual. A nation
is a body of living men. It may be broken up if wrongly led or
attacked by a superior force. When its proportion of men of
initiative or character is reduced, its future will necessarily
be a resultant of the forces that are left.

Dr. Seeck speaks with especial scorn of the idea that Rome died
of "old age." He also repudiates the theory that her fall was
due to the corruption of luxury, neglect of military tactics or
over-diffusion of culture.

'It is inconceivable that the mass of Romans suffered from
over-culture.[5] In condemning the sinful luxury of wealthy
Romans we forget that the trade-lords of the fifteenth and
sixteenth centuries were scarcely inferior in this regard to
Lucullus and Apicius, their waste and luxury not constituting
the slightest check to the advance of the nations to which
these men belonged. The people who lived in luxury in Rome were
scattered more thinly than in any modern state of Europe. The
masses lived at all times more poorly and frugally because they
could do nothing else. Can we conceive that a war force of
untold millions of people is rendered effeminate by the luxury
of a few hundreds? . . . Too long have historians looked on the
rich and noble as marking the fate of the world. Half the Roman
Empire was made up of rough barbarians untouched by Greek or
Roman culture.

Whatever the remote and ultimate cause may have been, the
immediate cause to which the fall of the empire can be traced
is a physical, not a moral decay. In valor, discipline and
science the Roman armies remained what they had always been,
and the peasant emperors of Illyricum were worthy successors of
Cincinnatus and Calus Marius. But the problem was, how to
replenish those armies. Men were wanting. The empire perished
for want of men.'

[5] "Damitsprechend hat man das Wort `Ueberkultur' uberhaupt
erfunden, als wenn ein zu grosses Maass von Kultur uberhaupt
denkbar ware."



In a volume entitled "Race or Mongrel" published as I write
these pages, Dr. Alfred P. Schultz of New York, author of "The
End of Darwinism," takes essentially the same series of facts
as to the fall of Rome and draws from them a somewhat different
conclusion. In his judgment the cause was due to "bastardy," to
the mixing of Roman blood with that of neighboring and
subjective races. To my mind, bastardy was the result and not
the cause of Rome's decline, inferior and subject races having
been sucked into Rome to fill the vacuum left as the Romans
themselves perished in war. The continuous killing of the best
left room for the "post-Roman herd," who once sold the imperial
throne at auction to the highest bidder. As the Romans vanished
through warfare at home and abroad, came an inrush of foreign
blood from all regions roundabout. As Schultz graphically
states:

'The degeneration and depravity of the mongrels was so great
that they deified the emperors. And many of the emperors were
of a character so vile that their deification proves that the
post-Roman soul must have been more depraved than that of the
Egyptian mongrel, who deified nothing lower than dogs, cats,
crocodiles, bugs and vegetables.'

It must not be overlooked, however, that the Roman race was
never a pure race. It was a union of strong elements of
frontier democratic peoples, Sabines, Umbrians, Sicilians,
Etruscans, Greeks, being blended in republican Rome. Whatever
the origins, the worst outlived the best, mingling at last with
the odds and ends of Imperial slavery, the "Sewage of Races"
("cloaca gentium") left at the Fall.

Gibbon says:

'This diminutive stature of mankind was daily sinking below the
old standard and the Roman world was indeed peopled by a race
of pygmies when the fierce giants of the north broke in and
mended the puny breed. They restored the manly spirit of
freedom and after the revolutions of ten centuries, freedom
became the parent of taste and science.'

But again, the redeemed Italian was of no purer blood than the
post-Roman-Ostrogoth ancestry from which he sprang. The "puny
Roman" of the days of Theodoric owed his inheritance to the
cross of Roman weaklings with Roman slaves. He was not weak
because he was "mongrel" but because he sprang from bad stock
on both sides. The Ostrogoth and the Lombard who tyrannized
over him brought in a great strain of sterner stuff, followed
by crosses with captive and slave such as always accompany
conquest. To understand the fall of Rome one must consider the
disastrous effects of crossings of this sort. Neither can one
overlook the waste of war which made them inevitable through
the wholesale influx of inferior tribes. Neither can one speak
of the Roman, the Italian, the Spaniard, the French, the
Roumanian, nor of any of the so-called "Latin" peoples as
representing a simple pure stock, or as being, except in
language, direct descendants of those ancient Latins who
constituted the Roman Republic. The failure of Rome arose not
from hybridization, but from the wretched quality on both sides
of its mongrel stock, descendants of Romans unfit for war and
of base immigrants that had filled the vacancies.

Greece.--Once Greece led the world in intellectual pursuits, in
art, in poetry, in philosophy. A large and vital part of
European culture is rooted directly in the language and thought
of Athens. The most beautiful edifice in the world was the
Peace Palace of the Parthenon, erected by Pericles, to
celebrate the end of Greece's suicidal wars. This endured 2,187
years, to be wrecked at last (1687) in Turkish hands by the
Christian bombs of the Venetian Republic.

But the glory of Greece had passed away long before the fall of
the Parthenon. Its cause was the one cause of all such
downfalls--the extinction of strong men by war. At the best,
the civilization of Greece was built on slavery, one freeman to
ten slaves. And when the freemen were destroyed, the slaves, an
original Mediterranean stock, overspread the territory of
Hellas along with the Bulgarians, Albanians and Vlachs,
barbarians crowding down from the north.

The Grecian language still lives, the tongue of a spirited and
rising modern people. But the Greeks of the classic period--the
Hellenes of literature, art and philosophy--will never be known
again. Says Mr. W. H. Ireland:

'Most of the old Greek race has been swept away, and the
country is now inhabited by persons of Slavonic descent.
Indeed, there is a strong ground for the statement that there
was more of the old heroic blood of Hellas in the Turkish army
of Edhem Pasha than in the soldiers of King George.'

The modern Greek has been called a "Byzantinized Slav." King
George himself and Constantine his son are only aliens placed
on the Grecian throne to suit the convenience of outer powers,
being in fact descendants of tribes which to the ancient Greeks
were merely barbarians.

It is maintained that the modern Greeks are in the main the
descendants of the population that inhabited Greece in the
earlier centuries of Byzantine rule. Owing to the operation of
various causes, historical, social and economic, that
population was composed of many heterogeneous elements and
represented in very limited degree the race which repulsed the
Persians and built the Parthenon. The internecine conflicts of
the Greek communities, wars with foreign powers, and the deadly
struggles of factions in the various cities had to a large
extent obliterated the old race of free citizens by the
beginning of Roman period. The extermination of the Plataeans
by the Spartans and of the Melians by the Athenians during the
Peloponnesian war, the proscription of the Athenian citizens
after the war, the massacre of the Coreyrean oligarchs by the
democratic party, the slaughter of the Thebans by Alexander and
of the Corinthians by Mummius are among the more familiar
instances of the catastrophes which overtook the civic element
in the Greek cities. The void can only have been filled from
the ranks of the metics or resident aliens and of the
descendants of the far more numerous slave population. In the
classic period four fifths of the population of Attica were
slaves; of the remainder, half were meties In A.D. 100 only
three thousand free arm-bearing men were in Greece. (James D.
Bourchier.)

The constant little struggles of the Greeks among themselves
made no great showing as to numbers compared to other wars, but
they wiped out the most valuable people, the best blood, the
most promising heredity on earth. This cost the world more than
the killing of millions of barbarians. In two centuries there
were born under the shadow of the Parthenon more men of genius
than the Roman Empire had in its whole existence. Yet this
empire included all the civilized world, even Greece herself.
(La Pouge.)

The downfall of Greece,[6] like that of Rome, has been ascribed
by Schultz to the crossing of the Greeks with the barbaric
races which flocked into Hellas from every side. These resident
aliens, or metics, steadily increased in number as the free
Greeks disappeared. Selected slaves or helots were then made
free in order to furnish fighting men, and again as these fell
their places were taken by immigrants.

[6] Certain recent writers who find in environment the causes
of the rise and fall of nations, ascribe the failure of Greece
to the introduction in Athens and Sparta of the malaria-bearing
mosquito. As to the facts in question, we have little evidence.
But while the prevalence of malaria may have affected the
general activity of the people, it could in no way have
obliterated the mental leadership which made the strength of
classic Hellas, nor could it have injected its poison into the
stream of Greek heredity.



It is doubtless true at this day that "no race inhabits
Greece," and the main difference between Greeks and other
Balkan peoples is that, inhabiting the mountains and valleys of
Hellas, they speak in dialects of the ancient tongue.
Environment, except through selection and segregation, can not
alter race inheritance and the modern "Greeks" have not been
changed by it. Schultz observes:

'We are told that the Hellenes owed their greatness largely to
the country it was their fortune to dwell in. To that same
country, with the same wonderful coast line and harbors,
mountains and brooks, and the same sun of Homer, the modern
Greeks owe their nothingness.'



In other words, it is quite true that the Greece of Pericles
owed its strength to Greek blood, not to Hellenic scenery. When
all the good Greek blood was spent in suicidal wars, only
slaves and foreign-born were left. " 'Tis Greece, but living
Greece no more."[7]

[7] In contrasting a new race with the old--as the modern
Greeks with the incomparable Hellenes--we must not be unjust to
the men of to-day whose limitations are evident, contrasted
with a race we know mainly by its finest examples. In spite of
poverty, touchiness and vanity characteristic of the modern
Greek, there is good stuff in him. He is frank, hopeful,
enthusiastic. The mountain Greek, at least, knows the value of
freedom, and has more than once put up a brave fight for it.
The valleys breed subserviency, and the Greeks of Thessaly are
said to be less independent than the mountain-born.



Furthermore, we do not know that even the first Hellenes of
Mycenae were an unmixed race, or that any unmixed races ever
rose to such prominence as to command the world's attention. We
do know that when war depletes a nation slaves and foreigners
come in to fill the vacuum, and that the decline of a great
race in history has always been accompanied by a debasing of
its blood.

Yet out of this decadence natural selection may in time bring
forward better strains, and with normal conditions of security
and peace nature may begin again her work of recuperation.

In the fall of Greece we have another count against war,
scarcely realized until the facts of Louvain and Malines, of
Rheims and Ypres, have brought it again so vividly before us.
War respects nothing, while the human soul increasingly demands
veneration for its own noble and beautiful achievements. As I
write this, there rise before me the paintings in the "Neue
Pinakothek" at Munich, representing the twenty-one Cities of
Ancient Greece, from Sparta to Salamis, from Eleusis to
Corinth, not as they were, "in the glory which was Greece," not
as they are now, largely fishing hamlets by the blue Aegean
Sea, but as ruined arches and broken columns half hid in the
ashes of war, wars which blotted out Greece from world history.



ANTI-SUFFRAGISTS AND WAR

BY ELSIE CLEWS PARSONS

NEW YORK CITY

ONE of the most curious of those misstatements of fact and
confusions of thought the conservative seems even more prone to
make than the radical has to do with a certain suppositiously
historical relation between women and war. It is assumed[1]
that early society is ever militant and that because of its
militarism it excludes women, women not being fighters, not
only from its government, but from all its privileges, even
making of them its drudges and its beasts of burden. And so,
argues the conservative, women are for the same reasons
disfranchised, and properly disfranchised, to-day. Whether more
or less militant than it was, society is still founded on
force, and because women are not as strong as men, men will not
give them the vote. Besides it is only right, since they can
not fight, they should not vote. It has always been so, and so
it should continue to be, at any rate until war becomes a thing
of the past, and that will never be, you can't change human
nature, etc., etc.

[1] And, let us admit, not merely by the conservative
anti-feminist. As radical and discerning a feminist as Thomas
Wentworth Higginson, after asserting that physical strength was
once "sole ruler," cites in agreement Walter Bagehot's
reference to "the contempt for physical weakness and for women
which marks early society." ("Women and the Alphabet," p. 49.
Boston and New York, 1900.)



There are of course various answers to this militarist
anti-suffrage argument, answers which in spite of the logic of
current events are still likely to be satisfactory or not
according to previous convictions, but the only point I wish to
challenge is the appeal in this connection to the past. Let the
militarist anti-suffragist assert his belief in government by
force if he likes, but let him not try to justify it by the
precedents of primitive life. Nor may he--or she--explain the
exclusion of women to-day as a survival of their subjection in
primitive society to brute force. The government of primitive
society is not based on physical prowess, and although modern
woman is excluded from men's activities for the same reason as
primitive woman was excluded, the reason is not muscular
inferiority.

It is a pity in the feminist controversies of the last hundred
years or so that the "exclusion of women" did not become a more
popular phrase than the "subjection of women." That term gave a
fallacious twist both to observation and analysis. Primitive
and modern men alike commonly EXCLUDE women, they seldom
subject them. Similarly, in some societies, children and young
people, all in fact but the elderly, are treated to methods of
exclusion rather than of subjection.

Early society is dominated by the elders; its practices and
customs have been determined by them and, in the most primitive
society, government is nothing but a gerontocracy, a government
of old men. Even with chieftaincy the council of the elders is
weighty and the heads of households have considerable
influence. Are the elders the fighters or raiders of the tribe?
No, they are its judges, its legislators and, most important of
all, its magicians. Nor is the chief or king the fighter par
excellence of the tribe. But he too may be and often is the
tribal magician. Through their powers of magic elders and
chiefs are responsible for the weather, for the reproduction of
plants and animals, for the success of the crops, of hunts and
catches, for the health and general welfare of the people. And
in war? In war they are the most important personages too.
Because they fight? No, because in war too they make magic;
they charm the approaches to the village, they "doctor" the
trails or the weapons or the canoes, they make war medicine,
they invoke and propitiate the war gods. The warriors are the
younger men, men whose efforts would be vain without the
backing of their magic-working seniors or chiefs. The elders
make peace and declare war. And it is at their dictate that the
young men take to head-hunting or to raiding or even to
stealing women.

As to the subjection of women, what exists of it the elders are
responsible for. It is they who scare a girl or shame her into
being docile. It is they who marry her off against her will, it
is they who set her unending tasks or shut her up in idleness.
It is they who make her undergo the discomforts or miseries of
what we call conventional life or bully her into exile or
death.

With this control of girls or women the warriors, the "standing
army," have little or nothing to do, even less in primitive
life than in modern. It is the old people, the old women at
times as well as the old men. Again it is the old men who are
leaders in the exclusion of the women. In control of the
initiation of the youths, they separate them from their mothers
or sisters and often decree for the initiates a ceremonial
avoidance of all women for a set time. The penalties they
threaten--sickness, decrepitude, effeminacy--are too dire to
pass unheeded. This "avoidance" has been explained as due to
the monopolistic spirit of the elders. With their women they
want no interference by the youths. But a far more plausible
explanation, I think, takes the avoidance as a concentration
rite, so to speak, a symbol, if you like, of the life ahead,
the life in which the boys, "made" men, are going to have
little to do in public with women. For even after the special
avoidance of the initiation period ends, the segregation of the
sexes continues. Men keep together and away from women in their
club-houses, and in all the places of assembly which are
differentiated from the primitive club-house--the church, the
council, the workshop, the gymnasium, the university, the
play-house. And from all the interests which center in these
places men have from time to time excluded women, they have
excluded them from magic and religion, from arts and letters,
from games, from politics and, let me add, from war.

Why are men so exclusive? Because--the reason will seem almost
too simple, I fear, for acceptance--because now and always men
do not want to be bothered by women. Women get in our way, they
say, women are a nuisance. Almost anywhere away from home women
are a nuisance--in church organization, in the university, in
business, etc. Of course if women can be kept apart from us in
these activities and will stay in their place, if they join an
order of nuns or deaconesses, if they go to a separate college
in the university, if they will become good stenographers, we
don't mind having their cooperation, we welcome it. Women may
even go to war--as an absolutely separate division of the army,
said the men of Dahomi, as non-combatant pahia women or workers
of magic, said the Roro-speaking tribesmen of New Guinea, or as
Red (dross nurses, say the men of Europe and America. If we men
can be sure women will not interfere with us, we really do not
mind. Women have only to give us that assurance of
non-interference to make us doubt the assertion we sometimes
make that in going to war they are interfering with the order
of nature.



AN INTERPRETATION OF SLAVOPHILISM

BY ARTHUR D. REES

PHILADELPHIA, PA.

THERE are good reasons for believing that the Russians are
practically the greatest peace people in Christendom. They are
the least commercial in the competitive sense, the least
capitalistic also, and as a people, the least combative in
Europe, despite the wrecks of warring dynasties that ten
centuries have left upon their plains and the miscellaneous
strifes and calamities of all kinds that have beset them.

Always expanding along lines of least resistance; absorbing by
comparatively petty conquests, decaying or scanty peoples;
reaching Kamchatka in the Far East with more ease than she
reached the shores of the Baltic; never flinging her legions
far and wide victoriously as did Rome, Spain, France or Great
Britain--Russia remains to-day, for the most part, humble, and,
in reality, a conquered people, living, dreaming and preaching
a morality born both of this humility and of the physical
environment that has helped to foster it. All Muscovy can not
be judged by those few who live in the saddle--the Cossack
population, men and women, numbers only about two million--nor
by the pitiable pageant of despotism the observer beholds in
their land: pogroms, poverty, disease, distress, militarism,
orthodoxy and Pan-Slavism. Russia has a soul in spite of these;
a gentle and beautiful soul, only half revealed, and too much
concealed by her dilapidation and her dilemma; a peaceful soul,
abnormally humble and devout, and in respect to these qualities
unequalled in Christendom.

Since the age of Vladimir the Holy, "The Beautiful Sun of
Kief," in the tenth century, Russia has had the tradition of
international peace. Vladimir wandered over the country, sword
and battle ax in hand, like a reincarnation of Thor, armed with
his mighty and wondrous hammer. Then came his yearning for a
new religion--something to inspire his life better than
Perun--Russia's old god of thunder--and the other idols, and a
little later, the picturesque investigation of his peripatetic
commissioners having been completed, he became a Christian of
the Greek church, was baptized with many fine and grand
ceremonies, compelled his docile people to do likewise, and,
like a true Northman that he was--the great grandson of Rurik
of the Baltic wilds--he so impressed his frowsy hordes, half
Scythian and half Slav, that now in the hearts of their
descendants, in their popular songs and legends, in those
concerning Kief especially--a beautiful and pathetic strain of
music eight centuries old--he, Vladimir, is still the central
heroic figure; once a man, but now a kind of god, sent from
Heaven to rule, enlighten and bring peace to his people and be
known in story and song as "Vladimir the Holy, the Beautiful
Sun of Kief."

An old chronicle describes for us how his hordes drank their
cup of trembling at his hands. There, around about the low
hills of the southern Dnieper River, probably on the crumbling
sandstone cliffs of Kief--the city, studded with jewel-like
legends and famed for its "golden palaces," stood his
candidates for baptism; near by were priests from
Constantinople, gorgeously arrayed, chanting, in strains
unknown to the populace, the Greek church baptismal service.
Then the democratic immersion!--rich man, poor man and all, at
Vladimir's command, wade into the baptismal waters, some up to
their knees, some to their waists, some to their necks, and,
thus finding a new faith from Heaven, they crossed themselves
for the first time as the thunder rolled on high! Here is
Russia remembering her Creator in the days of her youth--and
forgetting Him ever since; from then on, Holy Russia! Possibly
Holy Vladimir, at any rate, for becoming, with that ceremony,
peaceable, except for self-defence, he gave up all of his idols
and his aggressive sword. The former he scourged and cast into
the river, the latter he sheathed in its scabbard. And all this
about 988--the first peace movement of Holy Russia. The faith
of it, and its vision and dream came early in her history and
have not yet gone out or been extinguished.

Before the next such movement, time enough passed by to give
the seasons and the winds and rains full opportunity to whittle
down old Kief's storied sandstone hills. In 1815, the
much-expanded realm of Muscovy, then a partner in the holy
alliance, proclaimed under Alexander the First, the ideal of
peace. This Czar declared he would rule as a father over his
children and in the interest of "justice, charity and peace,"
and, in so doing, created the leading precedent for the peace
program of Nicolas the Second.

Alexander, who in the first half of his reign ruled liberally
for the days of Napoleonic supremacy, no doubt was sincere in
his desire to govern in the "spirit of brotherhood," but in the
latter years of his power, he fell sadly short of this
standard.

Alexander the Second, the emancipator of forty-six million
serfs, may have had some world peace ideal in mind when he in
1874 promoted a conference in Brussels to codify the usages of
war, but the reaction from his earlier liberalism was setting
in about this time and, growing worse, led to his assassination
in 1881.

The next move in the direction of peace came, as the world
rather well knows, through the present Czar, Nicolas the
Second, who on ascending the throne in 1894, proclaimed that
Russia would rule in the interests of peace and would cultivate
the arts of it. In 1898 followed the first call for a World
Peace Conference, and in 1899 came another circular with a
similar object.

But it is out of the kind heart of Muscovy, and from the
troubled, humble and penitent soul of Russia that the real
peace movement of her land has arisen. For many centuries
calamities have been pouring upon her plains, profusely
pouring--drought, famine and invasions without number; now
Rurik and his Northmen to start the empire out of its
prehistoric lethargy; their dynasty of conquering blood still
sharing in the rulership of the land to-day; now the Tartars,
remnants of whom with their high cheek bones are still visible
in the Baltic provinces; particularly and always and ever
poverty beyond description; poverty, disaster and conquest,
like triple demons to humiliate the soul of Russia and keep her
dumb for many centuries, except for the beauty of her unending
song.

And out of these conditions of life has grown the peace
morality that is native to the Russian people; out of their
sorrows and their conquered plains, out of their broken hearts
too, although the economic genesis of it all is very apparent.

The Russian people's Russia has ever been under the overlords
heel, downtrodden years without number, and yet it is a land
which has never produced a system of military tactics and
training--forever dependent for these creations upon her
neighbors; a land which has produced scarcely one great naval
or military commander who to-day holds a place in history as do
those of other nations; a land whose people have been usually
led to slaughter like sheep by Northman or Teutonic or Polish
generals; whose armies have never been noted for their great
campaigns, and always have been poorly drilled, managed and
fed, and never yet successful in any foreign wars. Surely from
such a land as this, no widespread war-morality or
world-conquering legions could come.

In fact the very reverse has come to pass: the philosophy of
Slavophilism has arisen in Muscovy, yet not so much arisen as
it has developed with the Russian soul, not as a thing apart,
but as a quality thereof, blossoming somehow with all other
Russian things, out of the primitive Scythian darkness. The
rebellious spirit having been crushed out of the generations
since, what is left but non-resistance? Yet in these latter
years a resisting spirit, nursed and suckled largely in western
Europe, has falsely made it appear that all Russia was in arms,
storming with chaotic unity at the church, the state and the
army, deluging their ancient customs with the destructive and
re-creative might of radicalism. Far and wide of the truth is
this! Let no one think the vast heart of Russia has changed!
Only the few have cast away the ancient quiet; only the few
have the modern consciousness instead of the medieval,
theocratic one; only the few are not at heart Slavophiles in
feeling and in morality.

This philosophy existed long in the national or social mind
before it was crystallized into public doctrines, and exists
even yet largely in its more primitive unworded or instinctive
form, although it was Peter the Great who unconsciously awoke
the latent and then unexpressed Slavophilic feelings and
moralities when he, like a civilizing Pied Piper, charmed the
chieftains of industry of Western Europe to follow his trail
into Muscovy, his "Empire of Little Villages," and there
regenerate them.

Therefore at about the end of the seventeenth century in
Russia, the "dumb silent centuries" gradually became articulate
in expressing their opposition to all things western. This is
the heart of Slavophilism, and no one can truly fathom the
Russian soul before understanding its philosophy. It is the
Muscovite theory of the simple life, still crying out against
the Great Peter's work and recalling the devotees of western
culture to its idealization of medieval, theocratic, autocratic
Russia.

Despite this reaction, however, it has a great meaning, a
tender beauty, and a message of depth and power for our western
world. Primarily Russia is a peasant and an agricultural land,
and there is a colorless monotony in her vast plains. Indeed
land and people are alike; as in the average peasant there is
patience, resignation and submission, so there is in the very
land itself. Open and prostrate it lies beneath the torrid sun
of the south, and the arctic winds of the north; subdued and
downtrodden for centuries, it and its people have always been
at the mercy of ruthless men and rainless winds.

Thus passive endurance has become one of the saving qualities
of the Russian's soul. The peasant's nature is one that has few
wants and little rebellious power. The Greek church of the
simple gospel is his and a government of the Czar's will. His
power of self renunciation is one which in Slavophilic thought
gives him true liberty. Therefore ask the followers of this
doctrine, what need is there of the constitutional liberties of
the west, or its republics or limited monarchies, or its
differences in ecclesiastical faith and structure? Slavophilism
declares that Russia has the only true freedom, faith and
brotherhood, which other lands sadly lack. In addition she has
the ancient and splendid heritage of the communal land system,
wherein the inherent justice of the Russian peasant's heart is
shown by his voluntary division and re-division of the land
among his brothers at stated times.

What need therefore, Slavophilism asks, for the degenerate
justice of the west? None! Away with Europe then!--the Europe
of competition and gruesome factories! The Europe of
destructive forces, of greedy land grabbers, of capital and
labor wars, where society is held together, not as in Russia by
the ties of affection, brotherhood and communal interest, but
only by money and greed, and where free thinkers, atheists and
materialists abound, whose lives and thoughts would unsettle
the holy, orthodox feelings of Russia, disturb her ancient
conscience and poison her humility with murmurings of
discontent and rebellion.

Away with the books of the west, too! And its agricultural
implements! Wooden ploughs instead of chilled steel! Outdoor
work and not indoor prisons called factories! Peasants working
for centuries beneath the uncanopied sun, and on the floors
without walls, will not let doors and brickwork thumbscrew
their souls in confinement thus! Indoors awhile in winter will
they labor, but spring airs shatter the moralities of the
time-clock and away to the fields they rush; in the spring to
sow and sing, in the summer to sing again and at the harvest
time too, and then to plait the bearded stalks into wreaths and
crown the maidens with sheaths of corn; the hymns for the
"death of winter" and the "birth of spring," marriage songs and
funeral dirges and chants of olden times well intermingled with
the labor of their hands.

Herein the poetry of agricultural, peaceable Russia clashes
with the prosaic efficiency of the west, the efficiency of
commercial wars, strikes and class struggles which peasant
Muscovy has known so little.

And again, Slavophilism, with its theory of successive
civilizations, culled perhaps from the philosophy of Hegel,
each civilization superior to its forerunner, comes to show us
a vision: the gradual displacement of one type of society by
another, but continuing what is best in the preceding until
nothing except what is good remains and universal peace
results, thus portraying the displacement of national
civilizations by universal ones, from which ultimately an
idealistic world policy will result, and the federation and
peace of men.

Some Slavophiles saw even in Peter's work a process of
progressing from nationality to universality. In his time there
was the same yearning toward its peaceful ideal. The "Old
Russia" party wanted Peter to renounce war and conquest.
Alexis, his own murdered son, worked with this element which
was very largely representative of the nation. To them, St.
Petersburg, then a new and growing capitol, was typical of
change, unrest and falsity; Moscow was in their hearts the only
capital, typical of Russia's old comfort and quiet. Many nobles
antagonized Peter, but he swept them aside, imprisoning them or
sending them to the gallows. Like Russia's slight resistance to
Rurik and others, and to the Tartars, so was her feebleness
before Peter the Great, who was himself, however, by no means
an accomplished military leader, but an enlightened barbarian,
dealing with a people whom writers and observers declare to be
endowed with conspicuous traits of humility, scarcely found in
the Christian nations of the western world.

Russian fiction represents its people in the same way.
Unaggressive characters, who talk and think but do not act,
fill its novels; they dream of the great age of the "Universal
Idea" that shall come for all and regenerate the "rotten west,"
where "rationalism is the original sin"; the typical west that
Slavophilism condemns--the west of the struggles between the
rulers and the ruled; between Scripture and tradition and the
upper and lower classes. The Slavophile idea, in theory at
least, leaves no room for this. Christian love and humility and
peasant communes, where rationalism, strife and rebellion are
unknown, must be instituted in the west; then the "Universal
Idea" of Russia will create Millennial times. This was the
"Messianic hope of Slavophilism," and perhaps is yet to a great
degree destined in the minds of its devotees to give the last
feature to the development of the world, so that the love and
feeling of the east would appease the discord of the west,
diluting its discipline and its logic with true religious
intuition and humility, and eventually the idealized
relationship of autocracy for the Czar and self-government for
the people--the old system so rudely strained by Peter the
Great--would permeate the ruled and rulers of the world.

Here then is Slavophilism! And pacific Russia--the heart and
soul of her, claiming this to be the true ethical and spiritual
ideal for her people, and censoring her upper class, with its
foreign culture, materialism, and infidelity, as being the only
real traitor to this saving morality of the ancient regime.

Among the prominent advocates of this philosophy might be
mentioned, first, Constantine Aksakoff, Russia's Rousseau, who
in the middle of the nineteenth century, was a virtuous
propagandist of the doctrine. He earnestly, even religiously,
preached the return of Russia from the allurements of western
Europe, unto her own theory of national salvation, declaring
that "the social order of the west is on a false foundation"
and that Slavophilism would offset its degeneracy, if only
Russia would free herself from the false class leadership for
whose origin the Great Peter stands the convicted sponsor! Thus
Slavophilism, under the leadership of Aksakoff, instead of
leading forward with the great liberal movement that came after
the Crimean War, resulting finally in the emancipation of the
serfs, would lead backward to the stagnant hours of medieval
Russia. Then there were no German words to disfigure the
Russian language! Then there were no German divisions of rank
among the officials to strangle life by their formality. No,
none of these, nor the disturbing importations of Peter; in
Aksakoff's variation of the gospel, the Russians are the
"beyond men" and need them not. Thus before Peter's reign all
was Slavophilic!--a religion of the simple Christian gospel, a
church considering itself the only true ecclesia, a government
of the Czar's will, a life of passive humility; creating
freedom of conscience and speech for the peasants, and freedom
of activity and legislation for the rulers, unknown in modern
corrupted Russia!

And thus was old peaceable-hearted Muscovy of the past
centuries pictured as the metropolis of true political and
individual morality.

Herzen, too, an able pamphleteer in revolutionary things,
preached something similar, crying from his pulpit at home or
in exile, that Russia would solve all her problems and lead the
human race by the simplicity of the Slavophile ideal. His early
and rabid westernism was greatly tempered on contact with the
west. Disillusion and disgust overcame him. The mercantilism of
the bourgeoisie there drove him into Aksakoff's fold, and he
too thereafter found faith alone in the "regenerative power of
Russia," and her system of the mir, the central sun of the
Slavophilic state, the village commune, self-governing and
self-contained. And then from that, this was to ensue: the
whole world made of village communes as in Russia, perhaps even
their log cabins too, and fresh mud to go with them on their
walls! But this did not deter the vision of these evangelists.
The commune was to be indefinitely extended; national and
international ones were to be organized, all self- governing,
and then would follow as the night the day, universal peace
wherever these communes were found.

This is the Utopia Russia has given to the world to stand
beside Plato's, or Sir Thomas More's or Morris's or Bellamy's.
This was the dream of pacific Pan-Slavism.

Dostoievsky himself is of it, and is luminous not with a mere
facet flash of its philosophy but with the whole orb of it. To
him the Russians "are more than human, they are pan-human."

Count Tolstoi too must be listed with these preachers. He,
making his own shoes and cutting his own and the peasants'
grain, lived it, showing how he thought the world's work ought
to be done. What were factories or the culture of the west to
him in later years--Shakespeare or no Shakespeare? Destructive
ideals of life. Competition, money and land greed,
self-assertion--all things that are the anthitheses of
Slavophilism--he shunned; mocking the palsied heart and
poisoned ideals of the west, and indeed of the "upper class"
section of his own land as no other Slavophile did. And
following its teaching, he journeyed through self-renunciation
to freedom and communal life, after repentance for his
wanderings, expiation and regeneration.

Dostoievsky, on the other hand, reached this philosophy largely
by being born to it among the humble people who lived it.
Melancholy-minded by nature--a sort of a Russian Dante but
living in actual infernos and purgatorios, Siberia and prison
cells, he came at last to worship his fellow countrymen and
their ideals as almost nothing else in heaven or earth, and
bowed down before them "as the only remnant left of Christian
humility, destined by Providence to regenerate the world." Here
is Slavophilism in a fervid extreme. "The Down-trodden and
Offended," "Memoirs of a Dead House," "Crime and Punishment,"
"Poor People,"--these, the titles of his novels, show the
predilections of his own soul. He died in the mystic frenzy of
this enthusiasm.

Here then, in this philosophy and in the lives of these men, is
something of the soul of Russia, beautiful in its humility, yet
not so humble that it is not ambitious to embrace the world in
the folding arms of its peace, its communal government and its
morality. Pan-Slavism of this nature is the only kind that in
truth can ever come from Russia. Pan-Slavism of the military
sort, with musketry, bribery and all other diabolic black arts,
miscalled government, rests on such a slim foundation that it
need be but little apprehended.

It was this brotherly humble soul of Russia that greatly helped
to put an end to the Russo-Japanese war: not merely failing
finances and lack of transportation. The feeling of a kindly
people for their own and a neighboring race caused widespread
mismanagement, opposition and wholesale desertions from the
army, among both the officers and the men. The Romanoff family
and official Russia caused the conflict, but human Russia,
humble and poor, was a great factor in its conclusion.

There is no doubt, however, that a certain number of
Slavophiles are addicted to the military mania, and this form
of their belief is more dangerously reactionary than its
ordinary phase. Many of these belong to the bureaucratic caste.
Official Russia holds aloft the eagle; human Russia the dove.
Official Russia leads the anti-Jewish massacres; human Russia
is very little responsible for pogroms. Ignatieff, "Father of
Lies," a bureaucrat of the military Pan-Slavic breed, about
1882, began the worst persecutions against the Jews in the last
generation, and possibly Pobiedonosteff, the late procurator of
the Holy Synod, was the worst offender in this one. The
peaceful feelings of the masses of the people, however, do not
sanction these outbreaks, and Slavophilism of such a sort is
not the philosophy of the Russian heart, no matter how many
pogroms may be enumerated.

It is therefore to human Russia that one must look for the true
feelings of the people; to their faith and deeds, to the
humility of their devotions, and prostrations before their
numberless shrines and ikons, to their religious ceremonies in
the open fields for huge detachments of the army, to the
thousands of their yearly pilgrims to Jerusalem, to their
superstitions, their poverty and long-suffering, all of which
attest innate passive endurance and non-resistance, and show
their kind of Slavophilism, which all in all, is much more than
"mere reverence for barbarism."

The war-time excitement in their cities seemed characteristic
of this national soul: "Russia is the Mother of Servia" was the
street cry of the marching throngs. It might be added that the
word mother, "matushka," is a prevalent one in expressing their
feelings. They call their greatest river the "Mother Volga."
Conquering Rome said "Father Tiber" and the native warriors of
this continent called the Mississippi the "Father of Waters."
The difference in these appellations shows the tender quality
of the Russian soul, whose ardent sympathies in July, 1914,
were greatly aroused by the spectacle of a large nation
attacking a small one, notwithstanding whatever may be said to
justify that deed.

Finally, however, let it be added, that the one thing that will
recreate Russia in the image of the west, is capital. Once let
the vast sums that have invaded Muscovy be put, not to the
autocratic purpose of the official rulers, but into factories,
mines, city subways and transportation of all kinds,
irrigation, canals, agricultural implements and to other
productive uses, then capitalistic Russia will stand forth
shorn of the Slavophilic simplicities of non-resistance and
humility. Labor wars, practically unknown hitherto, yet now
beginning, will occur in much greater number and the peasant
class, still unified, will be torn asunder by differences in
wealth and interests; the middle class, now very small, will
grow to large proportions, and many destructive forces will
come upon the land which has hitherto mocked western Europe
because of their presence there.

The many centuries of peasant unity, with its beauty of
brotherhood, affection and communal interests, will come to an
end under such a new regime. Already competitive forces are
dissolving communism in land, and many of the old beauties of
Russia are disappearing. Capitalism will bring with it much
turmoil and strife, unhappiness and death, but also the dawn of
brighter hours; newer and better cities, cleaner water, better
food, houses and clothes, and after the stress of its first
attack is over, and Russia has evolved laws and means to
control and socialize the invader, it may be that the old
simplicities and beauties of life will return, and a greater
and holier Russia will arise, still able to teach and aid in
the regeneration of the rest of the world.



PHYSICAL TRAINING AS MENTAL TRAINING

BY DR. J. H. McBRIDE

PASADENA, CALIFORNIA

THE first duty of a people is to provide for the health of its
children. The possible human value of any country fifty years
ahead depends chiefly upon what is done by and for its
children. They are the future in the making.

History seems to justify the statement of Professor Tyler[1]
that conquering races have been physically strong races, and
that nations have failed when they became degenerate.

[1] Growth and Education," J. M. Tyler.



Dionysius, speaking of the advantage of virility in a nation,
said,

It is a law of Nature common to all mankind, which no time
shall annul or destroy, that those who have more strength and
excellence shall bear rule over those who have less.

This law applies equally to individuals. Skill, cunning and
reason play their part, but the animal quality of endurance is
always back of these and is often decisive in a contest.

Darwin said he had difficulty in applying the law of the
survival of the fittest to the facts of the destruction of
Greece until it occurred to him that in this instance the
strongest was the fittest. Civilized people's have been
destroyed by ruder races that were physically superior.

The children that are now in our schools will take to adult
life such foundation as heredity has furnished, with the
equipment that society may care to add. We of this day have no
greater obligation than to prepare these children mentally and
physically for the duties that maturity may bring. Man did not
escape the physical necessities of the body when he became
civilized; the advantages of health are as great to-day as when
our forebears lived in tents. Very few of the primitive man's
activities are left; what he did regularly and from necessity
we do incidentally, and usually for sport, and yet the demands
upon the energies of man have not been lessened, they have only
been changed in form.

Our educational authorities, though in many instances
interested in physical development of the young, have not given
the subject the important place in their program that it
deserves. This is not wholly due to indifference, but largely
to their ideals that were derived from classical-ascetic
standards.

In the medieval ideal the human body was animal and sinful, to
be despised and repressed. The mind was said to be the
spiritual element in man, representing the immortal part of his
nature, and therefore was the only part worthy of attention in
an educational system. From the fall of the Roman empire to the
later nineteenth century this ideal dominated education.

The medieval universities, including Oxford and Cambridge,
provided only for mental training. Their education was intended
for those who were to follow the professions or to become
scholars or gentlemen of leisure. Education was not intended to
prepare the great mass of men for the every-day work of life.

While only indirectly related to my subject, it is interesting
to recall that there was in this country in the early
nineteenth century much opposition to the establishment of
common schools for the masses. It was claimed that those who
belonged to the working classes did not need to be educated.
Our own colleges and universities were originally founded on
the old classical-ascetic model, so that the spirit of the
medieval period survived in the educational plan of this
country. It is only in recent decades that these institutions
have begun to depart from the older, formal, classical methods
that made education a privilege of the few, the average man
being deprived of the advantages of the training that he
needed. Because of this the humble millions of men and women
who wove and spun, and fed and housed the world were left out
of the educational scheme.

Some years ago a London weekly paper, which speaks for the
conservative class of England, in discussing certain suggested
innovations in English higher education, said that the great
merit of education at Oxford and Cambridge was that it was
"absolutely useless." By this it was probably meant that the
education was for a chosen few, was not intended to prepare men
for the practical work of life and was essentially and only an
intellectual and cultural training.

The change of attitude that is seen in our day is due chiefly
to two great discoveries: the re-discovery of the human body
and its relation to our mentality and the discovery of the mind
of the child and youth. We have found that man is an animal who
graduated from caves and dugouts and to whom even barbarism was
a lade and great achievement. That the human body was made by
the experiences of that rude life, and that since then we have
made no change in it except to stand on two feet. Neither have
we added one nerve cell or fiber to our brains since the day
when the cave was home and uncooked food the daily diet.

The conception of man as an animal has led to a study of him as
such. Educators as a class now concede that the physical man
must be considered as an essential part of their scheme, that
the brain is an organ of the body among other organs, and is
subject to the same laws and influenced by similar conditions.

The influence of the mind upon the body is a commonplace of
psychology, but the influence of the body upon the mind is of
equal importance, though less frequently emphasized.

Whatever one's theory of the nature of mind, it must be
considered in relation to the brain as the organ of its
expression. The mind has, too, a broader base than the brain,
for every organ of the body has some share in the mental
functions. Every physician knows that physical disease lowers
the quality of the thinking and, with the exception of a few
geniuses like Darwin and Leopardi, it makes impossible
intellectual work of a high order. Disorders of the internal
organs rob the brain of nourishment and weaken it, and by
obtruding their morbidness upon it they batter down its
resistances and lower the thinking power.

Though we can never know the history of man's origin, the lives
of the child and of the wild man help us to understand
something of the order of racial development. All the higher
mental faculties grow in the child as they grew in the
race--out of impulse, instinct, feeling; and from infancy to
maturity we recapitulate mentally and physically the early
human-making stages, short circuiting in twenty years the
race-process.

The life of physical activity that the child leads develops and
coordinates the brain and the muscular system. In this way the
great motor functions are organized in the brain and become
part of the physical basis of mind.

The older education that trained the intellect exclusively,
without reference to the practical demands of life or the needs
of the body, was inadequate in that it ignored the law of
thinking and doing. It is true that there is much to its
credit, as many fine spirits have testified. They at least
survived it.

Stanley Hall says "we think in terms of muscular movement," and
this expresses the most important single fact in the mature
mentality. That the mind is largely constituted of memories of
muscular movements is basic in development.

The muscles are the special organs of volition, the one part of
the body that the mind can directly command and act on. The
muscles are preeminently the mind's instruments, the visible
and moving part of its machinery. They are thought carriers,
and during the growth period their functional activities are
organized into the mental life. This is why "we think in terms
of muscular movement," and why muscular training supplies a
natural need of the developing mind.

The normal boy says little or nothing of what he thinks, but
much of what he is doing or intends to do. He has the motor
mind, the instinct for doing things by which he builds the
brain and body. It is nature's way of laying the foundation in
the individual as by the more tedious process of evolution she
laid it in the race. The mental development of the normal
infant is indicated by the increasing accuracy and delicacy of
muscular coordination. The feeble-minded child very early shows
its mental defect in the clumsy use of its muscles. Because of
the functional relation of the voluntary muscles and the
mentality, physical training is in a large degree mental
training. When by such training we give dexterity to muscles of
the growing person we are making possible better mental
development; that is, because of this relation of the mind to
action there is a direct mental discipline in the thought-out
processes of physical activity. If, then, we make physical
development a part of our educational process, we are taking
advantage of race tendencies, we are starting the individual as
nature started the race; we are laying the foundation in the
individual as it was originally laid in the race; we are
building as the race built.

Exclusively intellectual training may be sufficient for the
genius or for the few who have great initiative and
intellectual self-confidence, but for the great mass of boys
and girls this training is not sufficient. It does not prepare
the young for the kind of work that three fourths of them will
have to do. We are now beginning to recognize this and through
manual training, vocational guidance, etc., we are teaching
boys and girls how to do things, and this, too, has the
additional merit of being, in a measure, physical training.

Educators, until recently, have, in emphasizing the paramount
importance of mental training, lost sight of the needs of the
body. Their classical ideals and formal methods made dead
languages, mathematics, philosophy etc., the school diet of
boys whose normal hunger was for action, and for learning by
doing.

Sir William Hamilton, who wrote fairy tales in metaphysics for
a generation of Scotchmen, placed these lines over the doorway
of his lecture room.

               In earth there 's nothing great but Man;
      In Man there 's nothing great but Mind.

This sounds well, but it is poor philosophy. There is much in
earth that is great besides man and much in man that is great
besides his mind. The older type of metaphysician with his
staggering vocabulary and his bag of "categories" has now
chiefly a historic interest. In the modern view the
interdependence of mind and body is a fundamental fact of life.
As science reveals the physiologic marvels of the once despised
body, the latter grows in our respect, for we find that its
seeming humble functions are intimately related to our highest
powers. Sir William's couplet gives a hint of the dominance of
the classical method of his day. It overemphasized the
importance of reason and too often converted the youthful mind
into a rag bag of useless information. The educators of that
time and since have thought more highly of human reason than
experience justifies. With their medieval bias for a world of
will and reason, they drove the young with the whip and spur of
emulation toward what to them seemed the one possible goal,
intellectual achievement.

We exaggerate the share that reason has in conduct. In the
history of the race, which is epitomized in the life of every
individual, reason was a late outgrowth of feeling, passion,
impulse, instinct. It was these older faculties that ruled the
life of the primitive man who made the race, and it was through
them that the race gradually rose to reason by what Emerson
would call the "spiral stairway of development."

These functions of impulse and instinct dominate the life of
the child and they are only a little less potent in the conduct
of us grownups. Much of what we call reason is feeling, and
much of our life activities are due to desire, sentiment,
instinct and habit, which, under the illusion of reason,
determine our decisions and conduct. Some one has said that
reason is the light that nature has placed at the tip of
instinct, and it is certainly true that without these earlier,
basal faculties reason would be a feeble light. During the
growing period these are specially strong, and the important
thing is that they be guided and organized in relation to the
needs of maturity. In combining mental and physical training we
are in some measure furnishing this guidance, doing
intentionally what nature did originally without design.

In the uncivilized state the stress of life was chiefly
physical. The civilized man has to a large degree reversed this
old order, in that the use of the body is incidental in his
work, the stress being placed upon the brain. He piles his life
high with complexities and in place of life being for
necessities, and they few and simple, it is largely for
comforts which we call necessities, and Professor Huxley has
said that the struggle for comforts is more cruel than the
struggle for existence.

This stress which is put upon conscious effort in civilization
places a new and severe tax upon the brain. It intensifies and
narrows the range of man's activities; it causes him to
specialize and localize the strain to a degree that may be
dangerous. It is certainly true that every man has his breaking
strain, and there is nothing that will raise the limit of
endurance like a strong and well-developed body.

The Italian physiologist, Mosso, showed by an ingenious device
that when a person lying quite still was required to add a
column of figures, blood left the extremities and flowed toward
the brain. Any emotional state or effort of thought produces
the same result. This demonstration that we think to our
fingers' ends suggests the importance of a strong body as a
prompt support in mental work.

All our work, mental as well as physical, is a test of
endurance, not a test that is spiritual and non-material, but
even in the sphere of the mind it is plainly animal and
physical. Thinking is primarily a physical process and draws
upon the vital stores of every organ. The energy that makes
clear thinking possible depends largely upon the vigor of the
body, and to the extent that this fails, the brain functions
suffer. Therefore, any work, mental or physical, will be better
done and more easily done if the body is strong. Other things
being equal, the intellectual work of the strong man will be
better done than similar work by one of equal talent, but who
is not strong.

Big muscles are not necessary in physical development. Many
people are not designed for big muscles, and any attempt by
them to produce a heavy, massive development may do harm. What
is wanted is vigor, skill, muscular readiness and a reawakening
of the old associations of thought and action. Such training
goes further than thought and action, for it reaches all the
organs and adds immensely to the vital capacity and working
power of the individual.

The play instinct of the child is as old as the race, or older,
and is a vitally important factor, not only in physical
development, but also in mental development. In its destructive
and disorderly activities the child shows the later adult
forces in the formative stage. Old instincts and movements that
were once self-preservative and of serious meaning to a wild
ancestor reappear in the play of children, and, utilized
wisely, may under new form become a valuable possession of the
adult. There is a great big man, in fact, several possible men,
inside every boy. Through his running, jumping, fighting,
swimming, through impulse, instincts and emotions he is seeking
the man that is in him, and it is by this turbulent and
experimental course that he finally comes to the order of
maturity.

Every boy is a vitally coiled up set of springs pressing to be
released. Race-old energies are struggling in him for
expression, and play is the normal way to satisfy the great
demand. The child may miss some important things and yet get
on, but it can not, without severe and lasting harm miss the
instinctive activities of play.

In play and games the young are re-enacting these old muscular
coordinations and developing mind and body on the old
foundation. The boy's love of outdoor sports and the adventures
of hunting are significant. Those ancestors of ours who hunted
and fished and shaped with care their arrow heads were
developing a manual skill and thinking power that we inherit.
We use our muscles for more varied and possibly more finished
purposes, but it is through the patience and practise of their
rude lives that we possess the delicate uses of the hands and
the finer dexterities of the mind.

The boy who goes whistling to the fields, or hunts, or fishes,
or swims, is unconsciously reaching out toward later life and
is preparing for serious and bigger things.

The growing formative period of life is the time for good
physical development. Whatever is gained and fixed then is
permanent, as it becomes a part of the physiological habits of
the individual. The years before twenty decide the future
energy stores, and the capacity to endure. Every function
enlarged, every gain of power, is additional storage room for
energy, to be drawn upon in the coming days of adult stress.

Good physical development not only gives strength and skill in
the use of the body, but develops a physiological habit of
surplus power that may be called quantity of energy. Life is
not alone in quality, in delicacy of adjustment, in accuracy,
in fineness of feeling; it is also in quantity. The poet who,
with frail physique and feeble pulse, sits in his quiet retreat
and puts his fine fancies into the rhythms of verse has
quality. But in the stress and rivalry of life that awaits the
majority of men, there is a need for quantity of energy, such
as enabled a Washington or a Caesar or a Napoleon or a
Wellington to shoulder his way through difficulties. These men
combined quality with quantity and this combination may make,
and often does make, the life of masterful achievement. The
quantity of energy in us average men may make the difference
between success and failure.

Many men fail in life for lack of staying power, for lack of
that kind of endurance that is furnished by having power in
reserve.

The strong, confident person who has strength to spare,
reserves of energy, does his work easily and without friction.
Half the timidities and indecisions of men are chargeable less
to lack of ability than to lack of the physical vigor, the
QUANTITY of energy, which is the driving power of character. In
all the contests of life an important element in success is the
ability to endure prolonged stress, to have the reserve energy
that can be drawn upon and utilized as a driving force. This
power is not alone necessary in the emergencies, the "short
hauls" of life, but also in the long hauls that spread the
strain through greater periods. Many of the failures of life
are due as much to lack of ability to meet prolonged stress as
to lack of experience or intelligence. Men of moderate ability
but with great powers of endurance often succeed, while men of
greater talent fail for lack of the ability to endure strain.

The man with a weak body and without the self-confidence that
surplus energy gives is liable to be of uncertain judgment.
Such a man in the presence of a problem requiring quick
decision, doubts and hesitates and stands shivering on the
brink of action while hastening opportunities pass him by.

Much of the loose thinking of our time is undoubtedly due to
poor educational drill. In fact the failure of the schools to
teach pupils how to apply the mind and how to think is one of
their common reproaches. Inability to use the mind effectively
is also frequently due to a lack of vigor and physical stamina.
A person with poor digestion, or under-developed body, or weak
circulation has of necessity a badly nourished brain. Such a
brain, unless it belongs to a genius, will do poor thinking.

The mentally trained person who is also physically strong has
the combination that puts his powers at easy command. He can be
joyously busy doing the impossible because the doing of it has
been made easy by training.

How much native power there is in all of us that for want of
proper training or sympathetic encouragement never comes to
maturity! How many of the finer qualities of character that,
for want of a kindlier climate of cheerful companionship and
wise direction, failed to mature and now lie dead in us! Very
many people are only partly alive. A large part, and in some,
the best part, is dead. The capacity they show is probably only
a small share of a fine inheritance which, not knowing how to
use, they allowed to die.

We have an instinctive liking for people who are strong and
healthy. They appeal to us by their robustness and their
confident display of energy. We do not now need the big muscles
that were once necessary in wielding spear and battle-axe. We
need, however, as much as the race ever needed well-developed
bodies and habits of health.

It is not difficult for us to see that sports and games and
play help to physical development, but it is not so plain that
they may be made to develop the best qualities of character.

It is a fact, however, that all the important elements of
character are tried out in games and sports. Enthusiasm,
self-confidence, the adventurous spirit, alertness, promptness,
unselfishness, cooperation, quick judgment--all these have
their training and discipline on the game field. They comprise
those fundamental native qualities that have gone to make
humanity what it is. The young should have this training, and,
if of the right kind, it may be made to contribute to the
making of the best kind of character. The same quickness and
accuracy of judgment that enable a boy to win a point in
football may in later life be used to win a battle or save a
business venture. Beyond this, there is of course gained the
strong body that makes work easy and stress less difficult to
bear.

Hall calls attention to the fact that two generations ago,
Jahn, the great builder of German physique, roused the then
despairing German nation by preaching the gospel of strong
bodies. He created a new spirit in Germany, and the whole
nation was aroused and seized with an enthusiasm for outdoor
games and sports, and there arose a new cult for the body. His
pupils sang of a united fatherland and of a stronger race. The
Germans are in the habit of reminding us that it was about one
generation after Jahn that the German Empire was founded and
Germany became a world power.

Every argument for the physical training of boys applies with
equal force to girls. Women need to be physically as strong as
men. No race will remain virile and progressive unless both the
fathers and mothers have the physical stamina that produces
healthy, vigorous offspring. In this age, when women are going
out into the world to compete with men it is highly important
that they be physically strong if they are to stand the stress
successfully. It was from rough barbarians, the rude war-loving
Teutonic men and women described by Tacitus, that the
Anglo-Saxon race inherited those splendid qualities of mind and
body that have made their descendants masters of seas and
continents.

It has been objected that gymnastics and field sports make
girls coarse and mannish. The exact opposite has been found to
be the case. It has been observed in colleges that when young
women are properly led, their sports, in place of making them
mannish, have a marked refining influence. They care more for
correct posture because this is made one of their tests in
athletic sports. They develop better manners and a new sense of
pride in their appearance. They soon learn to avoid slang, loud
talking and boisterous behavior. In the University of Chicago
where they have excellent training, many of the girls have said
that they came to have a new sense of dignity and to care more
for their personal appearance.

They also develop the finer elements of character, a
cooperative spirit, obedience to commands, patience,
self-confidence, a spirit of comradeship, a democratic attitude
and an appreciation of good qualities in others wherever found.
All of these esthetic, social and moral qualities, woven into
the texture of the growing character, and with the vigorous
health that the physical training brings, are the best
contribution to the making of the most effective type of the
womanly woman. All games and sports and athletics for the young
should therefore make for refinement and esthetic development.

The state needs now, and will always need, men and women who
have sound bodies and abounding energy.

The harsher phases of the human struggle may pass and wars may
cease, but the old contests of races, nations and individuals
will continue under other forms.

As the race grows older life will become more largely mental.
The increasing complexity of human relations and the more
delicate adjustments that these relations require will bring a
new and finer social order that will make higher demands upon
reason.

While there is no evidence that experience or time or training
will ever change the structure of the brain, it is probable
that we have as yet but imperfectly utilized our mental
possibilities. Stratton says:

     Out of the depths of the mind new powers are always
emerging.[2]

[2] "Experimental Psychology and Culture," George M. Stratton.



Back of the mental life, and making it possible, are the
energies of the body, the functioning of the animal in man,
which in the brain are changed to the higher uses of the mind.
The ability to execute, to act effectively, to do and keep
doing, to do the work of the professional man, the banker, or
the scientist, all this is primarily physical, and from top to
bottom of man's activities the physical test is applied. With
the mental and emotional strain of civilized life goes the
physical strain which is the other half of the struggle, and
which now and always is both mental and physical. The Greeks
recognized this unity of mind and body twenty-five hundred
years ago and their results remain unmatched by any race.

They saw that the thought-out movements of physical training
resulted in mental training and this law of mental development
through physical training was a fundamental principle in their
educational plan.

The nation that will again make this an ideal will produce a
finer race of men, and other things equal, will excel in all
that makes a people great.



EDWARD JENNER AND VACCINATION

BY PROFESSOR D. FRASER HARRIS, M.D., D.Sc.

DALHOUSIE UNIVERSITY, HALIFAX, N. S.



WE are so exceedingly apt to take our blessings as a matter of
course that at the present time a large number of us have quite
forgotten, and some of us have never known, what a terrible
disease smallpox is and from how much suffering national
vaccination has saved us. But even many of us, who may not be
included amongst those who know nothing of smallpox, do come
within the group of those who know next to nothing of the life
and work of Dr. Edward Jenner. A number of persons think he was
Sir William Jenner, physician to Queen Victoria.

An infectious or communicable disease is one caused by the
admission of some form of living matter into the body of a
human being or of a lower animal. All diseases are clearly not
communicable in the sense that they are due to the presence of
living things. Indigestion, for instance, I can not communicate
to my neighbor, however serious my dietetic indiscretions.

Now, while the actual microorganisms causing many of the
infectious diseases have been discovered in these recent days
through the agency of the microscope--one of science's most
valuable gifts to suffering humanity--a few diseases
undoubtedly infectious have, even up to the present time, not
had their microorganic causes discovered. Smallpox or variola
is one of these. The term variola is from the Latin varus, a
pimple.

The name Small Pox, which first occurs in Holinshead's
"Chronicle" (1571), was given to this disease to distinguish it
from the Great Pox or syphilis, the French disease, or Morbus
Gallicus which attained the proportions of an epidemic in
Europe about 1494. The expression "The Pox" in the older
medical literature always refers to the Lues Venereal The word
"pox" is the plural form of pock; the spelling "pox" is
phonetic; "pocks" is the correct form.[1]

[1] Thus the following expression in Galt's "Annals of the
Parish" is justified--"My son Gilbert was seized with the
smallpox and was blinded by THEM for seventeen days."



Smallpox is unquestionably a highly infectious or communicable
disease, and in the language of a past day, there is a virus or
poison which can pass from the sick to the unaffected; when
this transference occurs on a large scale we speak of an
epidemic of smallpox. As Sir William Osler truly says, "It is
not a little remarkable that in a disease, which is rightly
regarded as the type of all infectious maladies, the specific
virus still remains unknown." The same, however, is true of the
common diseases of scarlatina, measles and chickenpox. Of some
diseases, the virus is a bacillus or coccus, excessively minute
fungi recognizable only under the microscope; but the
bacteriologists are now beginning to speak of viruses so
impalpable that they, unlike ordinary bacteria, can go through
the pores of a clay filter, are filter-passers, that is are of
ultra-microscopic dimensions. Some authorities conjecture that
the virus of variola belongs to the group of filter-passers.
The virus of smallpox, however, is very resistant and can be
carried through the air for considerable distances; it clings
for long periods to clothes, books, furniture, etc.

I shall not now digress to give the clinical details of a case
of smallpox; the eruption may be slight or it may be very
extensive. It occurs in three forms, discrete, confluent and
hemorrhagic. The most dangerous form of smallpox is the
confluent, in which the face and arms particularly are covered
with large pustular areas of a most disfiguring appearance.

The disease called chickenpox, or varicella, has no
relationship to smallpox and does not protect from it, nor does
smallpox protect from chickenpox.

HISTORY OF SMALLPOX

There seems very little doubt that the home of smallpox was
somewhere on the continent of Africa, although it is true that
there are traditions pointing to its existence in Hindustan at
least 1000 B.C. One Hindu account alludes to an ointment for
removing the cicatrices of eruption. Africa has certainly for
long been a prolific source of it: every time a fresh batch of
slaves was brought over to the United States of America there
was a fresh outbreak of smallpox.[2] It seems that the first
outbreak in Europe in the Christian era was in the latter half
of the sixth century, when it traveled from Arabia, visiting
Egypt on the way. The earliest definite statements about it
come from Arabia and are contained in an Arabic manuscript now
in the University of Leyden, which refers to the years A.D. 570
and 571. There is a good deal of evidence that the Arabs
introduced smallpox into Egypt at the sacking of Alexandria in
A.D. 640. Pilgrims and merchants distributed it throughout
Syria and Palestine and along the north of Africa; then,
crossing the Mediterranean, they took it over to Italy. The
Moors introduced it into Spain whence, via Portugal, Navarre,
Languedoc and Guienne it was carried into western and northern
Europe. The earliest physician to describe smallpox is Ahrun, a
Christian Egyptian, who wrote in Greek. He lived in Alexandria
from A.D. 610 to 641. The first independent treatise on the
disease was by the famous Arabian physician, Rhazes, who wrote
in Syriac in 920 A.D., but his book has been translated into
both Greek and Latin. The first allusion to smallpox in English
is in an Anglo-Saxon manuscript of the early part of the tenth
century; the passage is interesting--"Against pockes: very much
shall one let blood and drink a bowl full of melted butter; if
they [pustules] strike out, one should dig each with a thorn
and then drop one-year alder drink in, then they will not be
seen," this was evidently to prevent the pitting dreaded even
at so early a date. Smallpox was first described in Germany in
1493, and appeared in Sweden first in 1578.

[2] Osler thinks the pesta magna of Galen was smallpox; Marcus
Aurelius died of it.



The contributions of Sydenham, the English Hippocrates, to the
knowledge of smallpox, are classical.

Throughout the Middle Ages, owing to the very crowded and
unsanitary state of the cities of Europe, smallpox was one of
the various plagues from which the inhabitants were never free
for any length of time.[3] Leprosy, influenza, smallpox,
cholera, typhus fever and bubonic plague constituted the
dreadful group. In most countries, including England, smallpox
was practically endemic; an attack of it was accepted as a
thing inevitable, in children even more inevitable than
whooping-cough, measles, mumps or chickenpox is regarded at the
present time. There was a common saying--"Few escape love or
smallpox." In the eighteenth century so many faces were pitted
from severe smallpox that it is said any woman who had no
smallpox marks was straightway accounted beautiful. Very few
persons escaped it in either the mild or the severe form in
childhood or in later life.

[3] England was by no means exempt, but it was not infection in
the modern sense that Shakespeare meant when he wrote--
                       "This England,
      This fortress, built by Nature for herself
      Against infection and the hand of war."



Now it is characteristic of a microorganic disease that a
person who has recovered from an attack of it is immune from
that disease for a longer or shorter time, in some cases for
the remainder of life. This is, luckily, as true of smallpox as
of any of the other acute infections. We do not now need to
enquire into the theory of how this comes about; it is a
well-recognized natural phenomenon. The modern explanation is
in terms of antigens and anti-bodies and is fast passing from
the stage of pure biochemical hypothesis into that of concrete
realization. Persons who have recovered from smallpox rarely
take it a second time; the few who do, have it in a mild form.
It follows, then, that if smallpox is purposely inoculated into
a human being he will for a long time be resistant to the
subsequent infection of smallpox. The fact of smallpox
protecting from smallpox is by no means without analogy in
other diseases. Thus in Switzerland, in Africa, in Senegambia,
it has been the custom for a long time, in order to protect the
cattle from pleuro-pneumonia, to inoculate them with the fluid
from the lung of an animal recently dead of pleuro-pneumonia.
Of course since the time of Pasteur we have been quite familiar
with the inoculation of attenuated virus to protect from the
natural diseases in their fully virulent form, for instance,
anthrax, rabies, plague and typhoid fever.

As it was, then, known to mankind from a very early period that
a person could be protected from smallpox by being inoculated
with it, inoculation grew up as a practice in widely distant
parts of the globe. The purpose of intentional inoculation was
to go through a mild attack of the disease in order to acquire
protection from the much more serious natural form of the
disease--to have had it so as not to have it. A very high
antiquity is claimed for this smallpox inoculation, some even
asserting that the earliest known Hindu physician (Dhanwantari)
supposed to have lived about 1500 B.C., was the first to
practice it. Bruce in his "Voyages to the Sources of the Nile"
(1790) tells us that he found Nubian and Arabian women
inoculating their children against smallpox, and that the
custom had been observed from time immemorial. Records of it
indeed are found all over the world; in Ashantee, amongst the
Arabs of North Africa, in Tripoli, Tunis and Algeria, in
Senegal, in China, in Persia, in Thibet, in Bengal, in Siam, in
Tartary and in Turkey. In Siam the method of inoculation is
very curious; material from a dried pustule is blown up into
the nostrils; but in most other parts of the world the
inoculation is by the ordinary method of superficial incision
or what is called scarification. By the latter part of the
seventeenth century inoculation for smallpox was an established
practise in several European countries into which it had
traveled by the coasts of the Bosphorus, via Constantinople. In
1701 a medical man, Timoni, described the process as he saw it
in Constantinople. Material was taken from the pustules of a
case on the twelfth or thirteenth day of the illness. As early
as 1673 the practice was a common one in Denmark, Bartholinus
tells us. In France inoculation had been widely practiced; on
June 18, 1774, the young king Louis XVI., was inoculated for
smallpox, and the fashionable ladies of the day wore in their
hair a miniature rising sun and olive tree entwined by a
serpent supporting a club, the "pouf a l'inoculation" of
Mademoiselle Rose Bertin, the court milliner to Marie
Antoinette. In Germany inoculation was in vogue all through the
seventeenth century, as also in Holland, Switzerland, Italy and
Circassia. In England the well-known Dr. Mead, honored, by the
way, with a grave in Westminster Abbey, was a firm believer in
inoculation, as was also Dr. Dimsdale, who was sent for by the
Empress Catherine II. to introduce it into Russia. Dr. Dimsdale
inoculated a number of persons in Petrograd, and finally the
Grand Duke and the Empress herself. The lymph he took from the
arm of a child ill of natural smallpox. For his services to the
Russian court Dr. Dimsdale was made a Baron of the Russian
Empire, a councillor of state and physician to the Empress. He
was presented with the sum of 1,000 pounds and voted an annuity
of 500 pounds a year. At the request of Catherine, Dr. Dimsdale
went to Moscow, where thousands were clamoring for inoculation.
The mortality from smallpox in Russia seems to have been still
higher than in the rest of Europe. The annual average death
rate on the Continent at the end of the eighteenth century was
210 per 1,000 deaths from all causes, while in Russia in one
year two million persons perished from smallpox alone. In
England in 1796, the deaths from smallpox were 18.6 per cent.
of deaths from all causes.

A great impetus was given to inoculation in England by the
letters of Lady Mary Wortley Montague, the wife of our
ambassador to Turkey, Edward Wortley Montague, and daughter of
the Duke of Kingston. In 1717 Lady Mary wrote a letter to her
friend Miss Chiswell, in which she explained the process and
promised to introduce it to the notice of the English
physicians. So convinced was Lady Mary of the safety of
smallpox inoculation and its efficacy in preserving from
subsequent smallpox, that in March, 1717, she had her little
boy inoculated at the English embassy by an old Greek woman in
the presence of Dr. Maitland, surgeon to the embassy. In 1722
some criminals under sentence of death in Newgate were offered
a full pardon if they would undergo inoculation. Six men agreed
to this, and none of them suffered at all severely from the
inoculated smallpox. Towards the close of the same year two
children of the Princess of Wales were successfully inoculated;
and in 1746 an Inoculation Hospital was actually opened in
London, but not without much opposition. As early as 1721 the
Rev. Cotton Mather, of Boston (U. S. A.), introduced
inoculation to the notice of the American physicians, and in
1722 Dr. Boylston, of Brooklyn, inoculated 247 persons, of whom
about 2 per cent. died of the acquired smallpox as compared
with 14 per cent. of deaths amongst 6,000 uninoculated persons
who caught the natural smallpox. There was, however, great
popular opposition to the practice of inoculation, and Dr.
Boylston on one occasion was nearly lynched.

While successful inoculation undoubtedly protected the person
from smallpox, sometimes the inoculated form of the disease was
virulent, and certainly all cases of inoculated variola were as
infectious as the natural variety. Inoculated persons were
therefore a danger to the community; and there is no doubt that
such persons had occasionally introduced smallpox into towns
which had been free from the natural disease. At the end of the
eighteenth century, just about the time of Jenner's discovery,
public opinion was strongly against the continuance of the
practice of inoculation, and as natural smallpox had not at all
abated its epidemic character, the times were ripe for "some
new thing."

Now there is a disease of cows know as cowpox or vaccinia (from
the Latin vacca, a cow) which is communicable to human beings.
It is thought to be due to the same virus which in pigs is
called swinepox and in horses "grease." Jenner believed
vaccinia to be the same pathological entity as human smallpox,
modified, however, by its transmission through the cow. For a
long time this view was stoutly resisted, but it has now been
accepted as probably representing the truth. The identity of
vaccinia and "grease" is certainly much more doubtful.

To many of Jenner's contemporaries the view that vaccinia had
at one time been a disease of human beings seemed unlikely; but
we are now in a far better position to admit its probability
than were those of Jenner's time. We have since then learned
that man shares many diseases with the lower animals,
tuberculosis, plague, rabies, diphtheria and pleuro-pneumonia,
to mention only a few. We have also learned that certain lower
animals, insects for instance, are intermediary hosts in the
life-cycle of many minute parasites which cause serious
diseases in the human being, amongst which malaria, yellow
fever and the sleeping sickness are the most familiar.

It appears to have been understood before Jenner's time that
persons who had acquired cowpox by handling cattle, but
especially by milking cows, were immune from smallpox. In the
reign of Charles II. it is well known that the court beauties
envied the dairy-maids because having had cowpox, they could
not take smallpox which all women so dreaded. Dr. Corlett tells
us that the Duchess of Cleveland, one of the King's mistresses,
on being told that she might lose her place in the royal favor
if she were disfigured by smallpox, replied that she had
nothing to fear as she had had cowpox. In 1769 a German, Bose,
wrote on the subject of cowpox protecting from smallpox. In the
year 1774 a cattle dealer, Benjamin Jesty, at Yetminster, in
Dorset, inoculated his wife and three children with cowpox.
None of them ever took smallpox during the rest of their lives
although frequently exposed to its infection. Jesty died in
1816, and it is recorded on his tombstone that he was the first
person who inoculated cowpox to protect from smallpox. Cowpox,
or vaccinia, though infectious for cows, is not transmissible
among human beings, in other words, as a disease of man it is
not infectious. Edward Jenner, the Englishman of Berkeley in
Gloucestershire, was the first person to think scientifically
on the fact that cowpox protected from smallpox. John Hunter
had said to him, "Jenner, don't think, try." Luckily, however,
he did both. Thinking alone avails little, experimentation
alone avails not much, but the one along with the other has
removed mountains. Just as Newton thought scientifically about
that falling apple and reduced our conceptions of the universe
to order, just as Watt thought scientifically about that
kettle-lid lifted by the steam and so introduced the modern era
of mechanical power brought under man's control, so Jenner
thought about and experimented with cowpox until he had
satisfied himself that he had discovered something which would
rid the human race forever of the incubus of an intolerable
pestilence.

It was in 1780 that Jenner set himself to study cowpox in a way
that had never before been attempted, for he was convinced that
in the having had an attack of the disease lay the secret of
the conquest of that world-scourge. He confided in his fried
Edward Gardner about "a most important matter . . . which I
firmly believe will prove of essential benefit to the human
race . . . should anything untoward turn up in my experiments,
I should be made, particularly by my medical brethren, the
subject of ridicule." Luckily he was quite prepared for both
ridicule and opposition; for has not everything new been
ridiculed and opposed? Galileo was opposed, Bruno was opposed,
Copernicus was opposed, Harvey was opposed, George Stevenson
was opposed, Pasteur was ridiculed and opposed, and so were
Darwin, Simpson and even Lister. The physiological inertia even
of the educated has too often blocked the path of advancement:
but Jenner is in illustrious company, a prince amongst the
hierarchy of the misunderstood.

The facts or surmises before Jenner at this date, then,
were--(a) Cowpox produces an eruption extremely like that of
mild smallpox, it is, therefore, probably a form of smallpox
modified by transmission through the cow; (b) And an attack of
cowpox protects from smallpox. To test these things
experimentally some one must first be inoculated with cowpox,
and, having recovered from the vaccinia, that same person must,
secondly, be inoculated with the virus of smallpox or be
exposed to the infection, and, thirdly, this person ought not
to take the disease.

In 1788 Jenner had a careful drawing made of the hand of a
milkmaid suffering from cowpox to demonstrate to Sir Everard
Home how exceedingly similar were vaccinia and variola. Home
agreed it was "interesting and curious," and the subject began
to attract some attention in medical circles.

In November, 1789, Dr. Jenner inoculated his eldest child
Edward, aged 18 months, with some swinepox virus, and as
nothing untoward happened, he inoculated him again with
swinepox on April 7, 1791. The child had a slight illness, very
like vaccinia, from which he rapidly recovered. The moment for
the crucial experiment was not yet; it came in due time, but
Jenner had to wait five years for it, and five years are a long
time to a man who is yearning to perform his crucial
experiment. Happily for suffering humanity, in the early summer
of 1796 the opportunity came; the hour and the man were there
together.

Cowpox had broken out on a farm near Berkeley and a dairy maid
called Sarah Neames contracted the disease. On May 14, 1796,
Dr. Jenner took some fluid from a sore on this woman's hand and
inoculated it by slight scratching into the arm of a healthy
boy eight years old, by name James Phipps. The boy had the
usual "reaction" or attack of vaccinia, a disorder
indistinguishable from the mildest form of smallpox. After an
interval of six weeks, on July 1, Jenner made the most
momentous but justifiable experiment, for he inoculated James
Phipps with smallpox by lymph taken from a sore on a case of
genuine, well-marked, human smallpox, AND THE BOY DID NOT TAKE
THE DISEASE AT ALL. Jenner waited till the nineteenth of the
month, and finding that the boy had still not developed
variola, he could hardly write for joy. "Listen," he wrote to
Gardner, "to the most delightful part of my story. The boy has
since been inoculated for the smallpox which, aS I VERNTURED TO
PREDICT, produced no effect. I shall now pursue my experiments
with redoubled ardor."

Here we are behind the scenes at a great discovery; "as I
ventured to predict"; prediction is part of scientific
theorizing; there is a place for legitimate prediction as there
is for experimentation. All discoverers have made predictions;
Harvey predicted the existence of the capillaries, Halley
predicted the return of his comet, Adams predicted the place of
the planet Neptune, the missing link in the evolutionary series
of the fossil horses had been predicted long before it was
actually found by Professor Marsh. Pasteur predicted that the
sheep inoculated with the weak anthrax virus would be alive in
the anthrax-infected field, while those not so protected would
all be dead. A prediction verified is a conclusion
corroborated, an investigator encouraged.

Early in 1797, through another outbreak of cowpox, Jenner was
able to inoculate three persons with variola, only to find as
before that they were immune from smallpox. He now felt himself
justified in preparing a paper for the Royal Society, the
highest scientific tribunal in England. The council, however,
returned him his paper with the remark that in their opinion
the amount of evidence was not strong enough to warrant its
publication in the Transactions. Jenner was wise enough not to
be discouraged, and so in June, 1798, he published the paper
himself under the title, "Inquiry into the causes and effects
of the Variolae-Vacciniae, a disease discovered in some of the
western counties of England, particularly Gloucestershire, and
known by the name of cowpox." This historic pamphlet, which
ranks with the great classics of medicine, was dedicated to Dr.
O. H. Parry, of Bath. Later on the Royal Society was sagacious
enough to elect the very man whose paper it had previously
refused.

While in London attending to the publication of his pamphlet,
Dr. Jenner called on the great surgeon Mr. Cline, and left some
cowpox virus with him for trial. Cline inoculated a young
tubercular patient with vaccinia and later with smallpox in no
less than three places. In due time this patient did not show a
sign of smallpox. So impressed was Cline with this remarkable
result that he wrote to Jenner thus: "I think the substitution
of cowpox poison for smallpox one of the greatest improvements
that has ever been made in medicine. The more I think on the
subject, the more I am impressed with its importance."

The word "vaccination" was coined by the French, so remarkable
for the aptness of their descriptive terms, and it has ever
since remained with us as a convenient expression for the
inoculation of vaccinia as protecting from variola.[4]

[4] It is certainly not necessary to point out that the
principle of vaccination has been one of wide application in
modern medicine. Our word "vaccine" testifies to this. A
vaccine is a liquid, the result of bacterial growth, injected
into a patient in order to render him immune from that
particular disease which is caused by sufficient infection with
the microorganisms in question, e. g., of typhoid fever or of
plague.



Dr. Jenner's views were now becoming known, and the critics and
the doubters had appeared: St. Thomas has always had a large
following. The most formidable of the early objectors was Dr.
Igenhouz, who had come to London to study inoculation for
variola, and had already inoculated, among other notable
persons, the Archduchess Theresa Elizabeth of Vienna. The
careless vaccinations of Doctors Pearson and Woodville at the
London Smallpox Hospital brought much apparent discredit on
Jenner's work. In all his early work Jenner used lymph obtained
directly from papules on the cow or calf, but Woodville in 1799
showed that excellent results could be got from arm-to-arm
vaccination. As this latter method is a very convenient one,
the technique was widely adopted. We have to remember that we
are speaking of a period about sixty years before Lister gave
to suffering humanity that other great gift, antisepsis: and so
many arms "went wrong," not because of being vaccinated, but
because the scratches were afterwards infected by the
microorganisms of dirt. Jenner knew well the difference between
the reaction of clean vaccination and that of an infected arm,
but a great many medical men of his time did not, and so he was
constantly plagued with reports of vaccinations "going wrong"
when it was septic infection of uncleansed skin that had
occurred. The explanation of these things by letter consumed a
very great deal of his valuable time. By the end of 1799 a
large number of persons had, however, been successfully
vaccinated. As one Pearson proved troublesome by starting an
institution for public vaccination on principles which Jenner
knew to be wrong, and as Jenner found himself virtually
supplanted and misrepresented, he came up to London in 1800 to
vindicate his position. The King, the Queen and the Prince of
Wales, to whom he was presented, materially helped on the cause
by countenancing the practice of vaccination. Lord Berkeley,
his Lord of the Manor, was in this as in all things a kind and
wise patron. In the United States of America vaccination made
rapid progress, having been introduced there under the good
auspices of Dr. Waterhouse, professor of medicine at Cambridge,
Mass. The discovery was announced with true American
informality as "Something curious in the medical line," on
March 12, 1799.

Things went even better on the continent of Europe; deCarro, of
Vienna, inaugurated vaccination with such zeal and
discrimination that it spread to Switzerland, France, Italy and
Spain. From Spain it passed over to Latin America. In Sicily
and Naples, "the blessed vaccine" was received by religious
processions. Sacco, of Milan, commenced vaccinating in 1801,
and in a few years had vaccinated 20,000. In Paris, a Vaccine
Institute was established; and Napoleon ordered all his
soldiers who had not had smallpox to be vaccinated. On Jenner's
application, the Emperor liberated several English prisoners
remarking--"What that man asks is not to be refused." Napoleon
voted 100,000 francs for the propagation of vaccination. Lord
Elgin introduced it into Turkey and Greece. The Empress of
Russia, Catherine II., was one of the greatest supporters of
Jennerian vaccination. She decreed that the first child
vaccinated in Russia should be called "Vaccinoff," should be
conveyed to Petrograd in an imperial coach, educated at the
expense of the state and receive a pension for life. The
Emperor of Austria and the King of Spain released English
prisoners at Jenner's request. There were statues of Jenner
erected abroad, at Boulogne and at Brunn, in Moravia, before
any in England. Thus the European countries showed their
gratitude to the Englishman whose patience, genius and absence
of self-seeking had rid them of the detestable world-plague of
smallpox. Vaccination was made compulsory by law in no less
than five European countries before it was so in the United
Kingdom in 1853. In eight countries vaccination is provided
free at the expense of the government. The clergy of Geneva and
of Holland from their pulpits recommended their people to be
vaccinated. In Germany, Jenner's birthday (May 17) was
celebrated as a holiday. Within six years, Jenner's gift to
humanity had been accepted with that readiness with which the
drowning clutch at straws. The most diverse climes, races,
tongues and religions were united in blessing vaccination and
its discoverer. The North American Indians forwarded to Dr.
Jenner a quaintly worded address full of the deepest gratitude
for what he had saved them from: "We shall not fail," said
these simple people, "to teach our children to speak the name
of Jenner, and to thank the Great Spirit for bestowing upon him
so much wisdom and so much benevolence."

There are two allusions to smallpox in "Don Juan," which was
published in 1819, showing to what an extent Jennerian
teachings were in the air. The first is:

 The doctor paid off an old pox
  By borrowing a new one from an ox.
                   (Canto I., stanza 129.)

The second is:

 I said the smallpox has gone out of late,
  Perhaps it may be followed by the great.
(Stanza 130.)



Before 1812, Jenner had been made an honorary member of nearly
every scientific society in Europe, and had received the
freedom of the cities of London, Edinburgh, Dublin and Glasgow.
The Medical Society of London presented him with a gold medal
struck in his honor; in Berlin in 1812 there was a Jennerian
festival on the anniversary of Phipps's vaccination. Addresses
and diplomas were showered on him, and in 1813 the University
of Oxford conferred on him the degree of M.D. honoris causa. As
he refused point blank to pass the examination in Latin and
Greek required by the Royal College of Physicians of London,
Jenner never obtained admission into that learned body. When
some one recommended him to revise his classics so that he
might become an F.R.C.P. he replied, "I would not do it for a
diadem"; and then, thinking of a far better reward, added: "I
would not do it for John Hunter's museum."

But while the pure in heart were thus receiving the blessing
offered them by the benovelent man of science, the pests of
society, those discontented and jaundiced ones who are always
to be found in the dark recesses of the cave of Adullam, were
not idle. Many of his medical colleagues did indeed sneer, as
some are always apt to do at any new thing however good. To all
these Jenner replied, and a very great deal of his valuable
time was consumed in arguing with them. But the sect of the
anti-vaccinators had arisen, and was to some extent organized.
Caricatures, lampoons, scurrilities, vulgarities and
misrepresentations, the mean, were scattered on all sides.
Nothing was too absurd to be stated or believed--that
vaccinated persons had their faces grow like oxen, that they
coughed like cows, bellowed like bulls and became hairy on the
body. One omniscient objector declared that, "vaccination was
the most degrading relapse of philosophy that had ever
disgraced the civilized world." A Dr. Rowley, evidently
imagining himself honored by a special participation in the
Divine counsels, declared that "smallpox is a visitation from
God, but cowpox is produced by presumptuous man. The former was
what Heaven had ordained, the latter is a daring violation of
our holy religion." It was rather hard to blame Dr. Jenner for
the origin of cowpox. It took much forbearance to endure this
sort of thing; but Jenner's was a first-class mind and he
evidently dealt leniently even with fools. It was not for the
first time in the world's history that a lover of mankind had
been spurned with the words--"He hath a devil and is mad."

Besides enduring all these mental and physical worries, and the
annoyance that the Royal Jennerian Society established in 1802
was so mismanaged that it collapsed in 1808, Jenner had spent a
very large sum of private money on the introduction of
vaccination. He had been, as he himself expressed it, "Vaccine
clerk to the whole world." Parliament, it is true, in 1801,
voted him a sum of 10,000 pounds which was not paid for three
years afterwards and was diminished by 1,000 pounds deducted
for fees, so that it barely recompensed him for his outlays. By
1806, the immensity of the benefit conferred upon his diseased
fellow-creatures having been recognized more perfectly in every
other country than his own, the British Parliament woke up, and
voted him a sum of 20,000 pounds, only one member representing
the anti-vaccinators opposing the grant. Parliament, which had
previously received from the Colleges of Physicians of London,
Edinburgh and Dublin the most favorable reports of the efficacy
of vaccination, decided to reestablish the Royal Jennerian
Institute. A subscription of 7,383 pounds from grateful India
reached Jenner in 1812. In 1814 he was in London for the last
time, when he was presented to the Emperor of Russia, Alexander
I., who told him that he had very nearly subdued smallpox
throughout that vast Empire. Jenner refused a Russian order on
the ground that he was not a man of independent means.

The management of the Institute caused him much concern in his
later years; he disapproved of the personnel and of many of the
details of its working. One of the last worries of his life was
an article in the November number for 1822 of the famous
Edinburgh Review. Although it contained a good deal of praise,
it was not favorable to Jenner, who said of it, "I put it down
at 100,000 deaths at least." I have ascertained that this
article was not written by the celebrated Francis Jeffrey,
although he was editor of the Review until 1829.

Jenner's life, apart from his great discovery and his
developing the practice of vaccination, has not much incident
in it. He was born on May 17, 1749, the son of the Rev. Stephen
Jenner, vicar of Berkeley, Gloucestershire, England, the same
Berkeley in whose castle, Edward II., the vanquished at
Banockburn, was murdered in 1327. Jenner's mother's name was
Head. Edward went to school at Wotton-under-Edge and at
Cirencester, and began to study medicine with a Mr. Ludlow, a
surgeon at Sodbury near Bristol. In his twenty-first year,
Jenner went to London as a pupil of the great John Hunter, in
whose house, he lived two years, during which time he was
entered as a medical student at St. George's Hospital. It is
interesting to know that while still a student he was asked by
Sir Joseph Banks to arrange and catalogue the zoological
specimens brought home by the circumnavigator Captain Cook in
his first voyage of 1771. Jenner devoted considerable attention
to natural history, to geology and to the study of fossils, on
which topics he kept up correspondence with Hunter long after
he left London. In the year 1788 he married a Miss Kingscote,
and settled down to practice in his native place. Mrs. Jenner
died in 1815, after which date Jenner never left Berkeley
again.

Curiously enough, it was not until 1792 that Jenner obtained
the degree of M.D., and it was not from an English university
at all, but from the University of St. Andrews in Scotland.
This university, the smallest although the oldest of the
Scottish universities, has therefore the honor of being the
Alma Mater to the epoch-making Englishman. I have seen the
entry of the name in the list of graduates for the year 1792;
it has evidently been misspelled, for the name is corrected.
The first foreign university to recognize Jenner's eminence was
Gottingen. In 1794 Jenner had an attack of typhus fever. Jenner
never cared for London or a city life, and although in 1808 he
was persuaded to take a house in town, he soon gave it up and
went back to his beautiful Gloucestershire. For many years he
practiced during the season in the pleasant health-resort of
Cheltenham. He loved the country, he studied lovingly the
living things around him there: many are familiar with a piece
of verse he wrote on "The signs of rain."

The year 1810 was a sad one for Jenner: his eldest son died,
and that noticeably depressed his health. In 1823 he presented
a paper to the Royal Society on the migration of birds, a
subject not even yet fully cleared up. On January 26, in the
same year, he was stricken with paralysis on the right side and
died within twenty-four hours. His body was buried in the
chancel of the parish church of Berkeley, where there is a
memorial window placed by public subscription. In person,
Edward Jenner was short and rather heavily built; his
expression of face was pleasant with a touch of sadness. All
reports agree that in dress he was conspicuously neat, looking
more like a gentleman-farmer than a physician, with his blue
coat, yellow buttons, red waistcoat, buff breeches and
top-boots.[5]

[5] He was painted by Sir Thomas Lawrence, by Northcote and by
Vigneron.



There is no disguising the fact that during his lifetime Dr.
Jenner was much more appreciated in foreign countries than in
England. The medico-social club of Alverton, near where he
lived, would not listen to him when he addressed them on
vaccination. The effort to collect enough money from the
medical men of England in order to place a marble statue to
Jenner in the nave of Gloucester Cathedral, was successful only
after a long delay. An attempt to erect a statue in London died
of apathy; but in 1858, 32 years after he died, a statue was
erected in Trafalgar Square. In 1862 it was removed to a quiet
corner of Kensington gardens; and perhaps its surroundings, the
trees, the flowers and the birds he loved are more suitable
than the effigies of those national heroes who served their
country by taking, not by saving life. No, Nelson the hero is
hardly the suitable companion for Jenner the hero.

There is no doubt that Jenner's medical contemporaries, at
least in England, failed to appreciate the magnitude of the
gift their colleague had presented not merely to his own
country, but to the world at large. The discovery had, of
course, been led up to by several different lines of
indication, but this in no way detracts from the genius of
Jenner in drawing his memorable inductions from the few facts
which others had known before his time. The fame of Newton is
no whit diminished because Copernicus, Kepler and Galileo lived
and worked before him, the credit due to Harvey is none the
less because many before his time had worked on the problem of
the heart and vessels, and because some of them, notably
Cesalpinus, came within a very little of the discovery of the
circulation; the achievements of Darwin are not to be belittled
because Lamarck, Malthus or Monboddo had notions in accordance
with the tenor of his great generalization of evolution among
living beings. Certainly Jenner had precursors; but it was his
genius and his genius alone which, putting together the various
fragments of knowledge already possessed, gave us the grand but
simple induction based on his own experiments that vaccinia
prevents from variola. It was too simple and too new to be
appreciated in all its bearings either by the medical men or
the laity of his own day. Its impressiveness is not inherent in
it, as it is in the mathematical demonstration of universal
gravitation, as it is in the atomic theory or in that of the
survival of the fittest through natural selection. The English
country doctor merely said in essence--"let me give you cowpox
and you will not get smallpox." Unless the fact of this
immunity is regarded as possessed by all the nations of the
world for ever more there is nothing particularly impressive in
it; and so it failed to impress his contemporaries. It is only
when we contrast the loathsomeness and danger of smallpox with
the mildness and safety of vaccinia and varioloid that we grasp
the greatness of the work which Jenner did for mankind. The
very simplicity of vaccination detracts from its impressiveness
unless its results are viewed through the vista of the
centuries. We need the proper historical perspective in this as
in all else. Thus viewed, however, the simplicity of the
procedure and the universality of its application are most
imposing. Vaccination does not, indeed, dazzle the scientific
imagination like some of the other generalizations of biology,
but it is one that has been gloriously vindicated by the
subsequent history of the world's hygiene.

Jenner knew himself to be a benefactor of the human race; he
would have been insincere if he had pretended otherwise; he
finished his first paper with these words: "I shall endeavor
still farther to prosecute this enquiry, an enquiry, I trust,
not merely speculative, but of sufficient moment to inspire the
pleasing hope of its becoming essentially useful to mankind";
and on his death-bed he said, "I do not marvel that men are not
grateful to me, but I am surprised that they do not feel
grateful to God for making me a medium of good."

In private life Dr. Jenner was amiable and kind-hearted. Dibden
said of him: "I never knew a man of simpler mind or of warmer
heart." He was particularly kind to the poor. Dr. Matthew
Baillie said of him: "Jenner might have been immensely rich if
he had not published his discovery."

We may in conclusion examine some of the objections to and
criticisms of vaccination. The objections can be classified as
those entertained (a) by medical men and (b) those by the
public generally.

The objections raised by medical men are now a matter of
ancient history. Each generation of medical men has refused at
first to admit any new teaching promulgated in its time;
physiological inertia is not at once overcome. The most
enlightened of Jenner's critics did really believe that he was
drawing too extensive an induction from insufficient data; this
was the position of the Royal Society in 1788; but the
Edinburgh reviewer of 1822 should have known better. The purely
technical criticisms of Jenner's work have by this time been
fully assessed and replied to. It is true that at one time it
was not clear what were the relationships of chickenpox and
smallpox, of vaccinia and variola, of vaccinia and varioloid,
of the various forms of pox in animals--cowpox, swinepox,
horsepox or grease--either inter se or to human smallpox. But I
do not suppose that in this year of grace 1914 there can be
found one properly trained medical man, acquainted with the
history of Jennerian vaccination, familiar with the ravages of
smallpox and with the protective power of vaccinia, who could
be induced, by no matter how large a bribe, to say that he
disapproved of vaccination or that he believed it did not
protect from smallpox. There are cranks in all walks of life,
but the medical crank who is also an anti-vaccinationist is
happily the rarest of them all.

The lay objectors--the professed anti-vaccinators--are with us
yet in spite of some very serious lessons which have been
taught them. We may pass by the objectors of the class who
believe that vaccinated persons cough like cows and bellow like
bulls; these objections go into the limbo of old wives' fables
or into the category of wilful misrepresentation. Unfortunately
there is a large class of persons who can believe the absurdest
nonsense about any subject which is particularly distasteful to
them.[6] Another class of objection is the sentimental
repugnance to the idea of being given one of the diseases of
"the lower animals." Now the fact is that already we share a
great many diseases with the lower animals, a few of them being
tuberculosis, anthrax, rabies, tetanus, cancer,
pleuro-pneumonia, certain insect-borne diseases, some parasitic
worm diseases and some skin diseases like favus. As the
knowledge of the lowly origin of many of our diseases is more
widespread, this sort of objection will die out.

[6] Antivaccinators constantly allude to calf-lymph as "filth";
if lymph is filth, then I am able to assure them that each one
of them has about three liters of it in his own body.



An objection which is worthy of more consideration is that in
being vaccinated a child is apt to contract some infectious
disease such as tuberculosis or syphilis which are the two most
dreaded. Now so long as arm-to-arm vaccination was the routine
practice, there was a remote probability that this sort of
accident might occur. It appears to be true that a few
accidents of this kind have occurred, just as a few arms have
become septic or had erysipelas develop in them. But when the
few such cases are compared with the millions and millions of
uncomplicated vaccinations, their importance becomes very
insignificant. Now that arm-to-arm vaccination is no longer
practiced, but fresh calf-lymph used for each child, these
accidental inoculations are a thing of the past. The ignorance
of cause and effect is responsible for a great deal of the most
childish objections to vaccination as to much else. One woman
lately told me that she could not have her child vaccinated
because a child in the same street was made a cripple for life
by being vaccinated. Could we have a better example of the
"post hoc sed non propter hoc."[7]

[7] Now and again, however, we have the sad spectacle of some
one really well educated but apparently either ignorant of
logic or desirous of wilfully misrepresenting facts. The Hon.
Stephen Coleridge has an article in the June (1914) number of
the Contemporary Review which is, to say the least of it,
highly immoral in ethics and statistics.

I shall examine only that part of it bearing on vaccination.
The statements are that in the last five recorded years, 58
persons died from smallpox vaccination (he means vaccination
against smallpox), whereas in the same five years, 85 persons
died from smallpox itself. The inference we are intended to
draw from these figures is that to be vaccinated is nearly as
fatal as to have smallpox itself.

Now this kind of argument is a very common one with
statistically immoral persons, and is known as the suppression
of the ratio. Before we can appreciate the fact that in five
years 58 persons died after being vaccinated, we at least need
to know the total number of persons who were vaccinated. If
only 58 persons were vaccinated and they all died, then the
mortality was 100 per cent., but if, as was practically the
case, thousands of infants in Great Britain were vaccinated in
five years, then if only 58 died after vaccination (although
not necessarily in consequence of it) the mortality falls some
thousands of a per cent. The suppression of the ratio, i. e.,
58/many thousands is the deceit that is practiced.

Fifty-eight per year for five years, is 11.6 deaths per year of
persons vaccinated: presumably these were infants: taking the
birth-rate in England as 30 per 1,000 living, we may say that
900,000 infants were born; deduct 100,000 as not vaccinated, we
have 800,000 infants vaccinated, of these 11.6 died after being
vaccinated, which is 0.0014 per cent. This is not much of a
mortality from any cause; but using Mr. Coleridge's own
figures, it is a splendid demonstration of the safety of
infant-vaccination, the opposite of what he pretends it shows.

Mr. Coleridge proceeds to tell us that in five years 85 persons
died of smallpox in Great Britain, i. e., an average of 17
persons per year. In other words 17 persons died of smallpox in
a country with 30 million inhabitants, or 0.000056 per cent. of
persons living, not a high mortality. And we strongly suspect,
may we hope, that those 17 were persons who had not been
vaccinated.

But in Pre-Jennerian days, 17 persons died of smallpox out of
every 100 persons dying from all causes.

Mr. Coleridge's figures, properly and honestly interpreted,
testify loudly to conclusions exactly the opposite of what he
desires to insinuate; he has no doubt taken the statistics of
the Registrar-General, but he has prostituted them.

Mr. Coleridge's paper could not be a better example of the art
of concealing the causes of phenomena.

He exhibits the following table:

Deaths from smallpox per annum per a million living:

1862-1870 ................................. 172.2
1871-1880 ................................. 244.6
1881-1890 .................................  45.8
1891-1900 .................................  13.3
1901-1910 .................................  12.8

So that the table shows that since 1880 in Great Britain the
deaths from smallpox per million per year have declined until
they are only about 1/14th of their original number.

The natural inference from these figures, viewed in the light
of the history of smallpox in Great Britain, is that compulsory
vaccination has been steadily eradicating the disease; but this
is not Mr. Coleridge's conclusion: He says it is due to the
large number of persons who have refused to be vaccinated! This
would be laughable if it were not really serious; it is sad and
serious that a man of Mr. Coleridge's education and social
position should so consistently mislead the uncritical readers
of the Contemporary Review to whose pages he has unfortunately
very free access. If Mr. Coleridge really believes these things
he is either very stupid or very ignorant; if he knows them to
be otherwise, but wilfully deceives the public, he is immoral.
He suffers from the worst form of bias, the anti-scientific.
{the end of long footnote}



There is still that group of persons who object to
everything--anti-vivisection, anti-meat eating, anti-breakfast,
anti-hats and of course also anti-vaccination. They are anti
the usual and the normal that are quite good enough for the
most of people. They generally also believe that the earth is
flat; they are past praying for, all we can do with them is to
look them, like the difficulty of Jonah and the whale, "full in
the face and pass on."

Many people at the present time allow themselves to be
persuaded into being anti-vaccinators because neither they nor
their deluders have ever known what an epidemic of smallpox is,
have never seen with their own eyes the awful spectacle of a
person suffering from smallpox in any of its forms--discrete,
confluent or hemorrhagic. Thanks to this very Jenner, the world
has now for 100 years been almost free from epidemic, virulent
smallpox and most perfectly so in the vaccinated countries, so
that millions, the majority, of Englishmen, have never seen a
case of smallpox at all. Not knowing the awful danger they have
escaped, through Great Britain having had compulsory
vaccination since 1853, they have become lax in their belief in
the necessity for the continuance of that precaution. "They
jest at scars that never felt a wound." Towns such as
Gloucester in England, in which a large number of children have
been allowed to grow up unvaccinated, have always been visited
sooner or later by a serious outbreak of smallpox. It must be
so; the laws of natural phenomena can not be changed to suit
the taste of those persons who are mentally incapable of
understanding them. They can not be evaded; ignorance of the
law is no more an excuse in the realm of natural than of
man-made law.

We now come to that undesirable product of present-day,
grandmotherly legislation, the conscientious objector. As I am
not a politician, I shall not say anything for or against the
policy of inserting in a bill which makes vaccination
compulsory a clause giving to the conscientious objector the
power or right to refuse to have his child vaccinated, but as a
medical man who knows a little of the history of medicine, I
can only describe it as gratuitous folly. I am one of those who
believe that the laity should have no say in the matter of
whether any given procedure is or is not advantageous for the
public health. The efficacy of universal inoculation of
vaccinia as a prophylactic against variola is a question of
scientific medicine to be decided on technical grounds and
ought not to be a matter open to debate by the public at all.
It is perfectly monstrous to suppose that the ordinary person,
quite untrained to weigh evidence for or against the
advisability of the carrying out of a particular form of
national immunization against a horrid disease, is qualified to
form any opinion. He might as well be consulted on the
advisability of making the channel tunnel or on the safest type
of aeroplane or on any other subject involving the technical
training of the engineer. To permit the so-called "man in the
street" to say whether he shall or shall not permit the
carrying out of some important piece of civic hygiene is to
introduce a principle subversive of all system and obstructive
of all progress in the science of public health. It is absurd
that in a case like this the pronouncements of the judges are
to be submitted to the criticisms of the jury. England has
already had one or two pretty severe lessons through allowing
such places as Gloucester and Leicester to exercise their right
of private judgment on the question of vaccination. In
Gloucester where there was at one time a vigorous
anti-vaccination movement, a serious epidemic overtook the city
a few years ago (1896). What science pronounces to be
beneficial, the layman must submit to. What we want in these
days is less superstition and more faith--in science. I am
informed that there are more than 2,000 unvaccinated children
in the schools of this city at the present moment, and all
because a piece of legislation allows any unintelligent,
prejudiced or credulous parent to decide on the momentous
question of the vaccination of his children.

Our quarantine regulations are extremely strict, and rightly
so, on the subject of smallpox; but is it not a farce to take
so much trouble about the health of our immigrants when inside
the city we are all the time encouraging a high degree of
receptivity towards this very disease? I should call this a
very clear case of straining at the international gnat and
swallowing the municipal camel. The community at present is at
the mercy of its least instructed members. A most sensible
suggestion is that if an outbreak of smallpox occurs in
Halifax, the cost of it should be borne by the unvaccinated and
by the anti-vaccinators. The fact is we have forgotten what
smallpox is like. In 1796 before Jennerian vaccination, the
death-rate from smallpox in England was 18.5 per cent. of
deaths from all causes; in London between 1838 and 1869 it was
1.4 per cent., while in 1871--the worst year for smallpox since
vaccination became compulsory--the deaths from smallpox were
barely 4.5 per cent. of deaths from all causes, a proportion
which was exceeded 93 times in the eighteenth century. At the
present moment the deaths from smallpox in London constitute a
little under 0.24 per cent. of deaths from all causes, or 77
times less than in pre-Jennerian times.

According to MacVail, in the pre-vaccination period smallpox
was nine times as fatal as measles and seven and one half times
as fatal as whooping cough. To-day in the vaccinated community
its fatality is negligable, in the unvaccinated it is as high
as it was in the Middle Ages. In the city of Berlin, where
vaccination is absolutely compulsory, there is no smallpox
hospital at all; the cases of smallpox in that city being only
a few unvaccinated foreigners. In 1912 the deaths in New York
City were as follow: 671 from measles, 614 from scarlatina, 500
from typhoid fever, 187 from whooping cough and 2 from
smallpox.

In London there were in 48 years of the seventeenth century no
less than 10 epidemics of smallpox; in the whole of the
eighteenth, 19; and in the nineteenth no epidemic at all during
which smallpox was responsible for more than one tenth of the
deaths from all causes in any one year.

In Sweden, the highest death-rate before vaccination was 7.23
per 1,000 persons, the lowest 0.30; under permissive
vaccination the highest was 2.57, the lowest 0.12; under
compulsory vaccination the highest was 0.94, the lowest 0.0005.

It is so frequently said that the disappearance of smallpox is
due not to vaccination, but to improved general hygiene, that
we must look into this criticism with some care. In the first
place, a large diminution in the mortality from smallpox
occurred before there was any great change in the unsanitary
conditions of the English towns, before there was any enforcing
of the isolation of patients either in hospitals or in their
own homes. Since the introduction of vaccination, measles and
whooping cough still remain in the status quo ante, while
smallpox has been exterminated in all fully vaccinated
communities, these two diseases of children are as prevalent as
ever in England even although the general sanitary conditions
have been immensely improved in that country. Of course the
effects of vaccination wear out in time, and that is why it is
well to be revaccinated once or twice. Now there has been a
remarkable progressive change in the age-incidence of smallpox
"which can only be explained," says Dr. Newsholme, "on the
assumption that vaccination protects children from smallpox and
that the protection diminishes, though it never entirely
disappears, as age advances.

The "conscience clause" should be immediately removed from the
act in which it was inserted on the grounds that it is weak and
reactionary in principle, not in the interests of the
development of the legislative aspect of the science of public
health, and that it permits in certain unintelligent
communities quite a considerable number of unvaccinated
children to grow up as a permanent menace to their town and
district.

When the history of medicine becomes more widely known, when
the principles of prophylactic inoculation are more generally
understood, when respect for science is the rule rather than
the exception, when great achievements in the saving rather
than the destroying of life are objects of national veneration,
then we may hope to see the day when it will be unhesitatingly
admitted that the discovery by Dr. Edward Jenner, the
Englishman, was one of the most momentous in the history of the
human race, and that his life was one of the noblest, most
unselfish and, in its far-reaching effects, most important that
has ever been lived on this planet.



THE VALUE OF INDUSTRIAL RESEARCH

BY W. A. HAMOR

MELLON INSTITUTE OF INDUSTRIAL RESEARCH, UNIVERSITY OF
PITTSBURGH

THE aim of all industrial operations is toward perfection, both
in process and mechanical equipment, and every development in
manufacturing creates new problems. It is only to be expected,
therefore, that the industrial researcher is becoming less and
less regarded as a burden unwarranted by returns.
Industrialists have, in fact, learned to recognize chemistry as
the intelligence department of industry, and manufacturing is
accordingly becoming more and more a system of scientific
processes. The accruement of technical improvements in
particularly the great chemical industry is primarily dependent
upon systematic industrial research, and this is being
increasingly fostered by American manufacturers.

Ten thousand American chemists are at present engaged in
pursuits which affect over 1,000,000 wage-earners and produce
over $5,000,000,000 worth of manufactured products each year.
These trained men have actively and effectively collaborated in
bringing about stupendous results in American industry. There
are, in fact, at least nineteen American industries in which
the chemist has been of great assistance, either in founding
the industry, in developing it, or in refining the methods of
control or of manufacture, thus ensuring profits, lower costs
and uniform outputs.

At the recent symposium on the contributions of the chemist to
American industries, at the fiftieth meeting of the American
Chemical Society in New Orleans, the industrial achievements of
that scientific scout, the chemist, were brought out
clearly.[1]

[1] In this connection, see Hesse, J. Ind. Eng. Chem., 7
(1915), 293.



The chemist has made the wine industry reasonably independent
of climatic conditions; he has enabled it to produce
substantially the same wine, year in and year out, no matter
what the weather; he has reduced the spoilage from 25 per cent.
to 0.46 per cent. of the total; he has increased the shipping
radius of the goods and has made preservatives unnecessary. In
the copper industry he has learned and has taught how to make
operations so constant and so continuous that in the
manufacture of blister copper valuations are less than $1.00
apart on every $10,000 worth of product and in refined copper
the valuations of the product do not differ by more than $1.00
in every $50,000 worth of product. The quality of output is
maintained constant within microscopic differences. Without the
chemist the corn-products industry would never have arisen and
in 1914 this industry consumed as much corn as was grown in
that year by the nine states of Maine, New Hampshire, Vermont,
Massachusetts, Rhode Island, Connecticut, New York, New Jersey
and Delaware combined; this amount is equal to the entire
production of the state of North Carolina and about 80 per
cent. of the production of each of the states of Georgia,
Michigan and Wisconsin; the chemist has produced over 100
useful commercial products from corn, which, without him, would
never have been produced. In the asphalt industry the chemist
has taught how to lay a road surface that will always be good,
and he has learned and taught how to construct a suitable road
surface for different conditions of service. In the cottonseed
oil industry, the chemist standardized methods of production,
reduced losses, increased yields, made new use of wastes and
by-products, and has added somewhere between $10 and $12 to the
value of each bale of cotton grown. In the cement industry, the
chemist has ascertained new ingredients, has utilized
theretofore waste products for this purpose, has reduced the
waste heaps of many industries and made them his starting
material; he has standardized methods of manufacture,
introduced methods of chemical control and has insured
constancy and permanency of quality and quantity of output. In
the sugar industry, the chemist has been active for so long a
time that "the memory of man runneth not to the contrary." The
sugar industry without the chemist is unthinkable. The Welsbach
mantle is distinctly a chemist's invention and its successful
and economical manufacture depends largely upon chemical
methods. It would be difficult to give a just estimate of the
economic effect of this device upon illumination, so great and
valuable is it. In the textile industry, he has substituted
uniform, rational, well-thought out and simple methods of
treatment of all the various textile fabrics and fibers where
mystery, empiricism, "rule-of-thumb" and their accompanying
uncertainties reigned. In the fertilizer industry, it was the
chemist who learned and who taught how to make our immense beds
of phosphate rock useful and serviceable to man in the
enrichment of the soil; he has taught how to make waste
products of other industries useful and available for
fertilization and he has shown how to make the gas works
contribute to the fertility of the soil. In the soda industry,
the chemist can successfully claim that he has founded it,
developed it and brought it to its present state of perfection
and utility, but not without the help of other technical men;
the fundamental ideas were and are chemical. In the leather
industry, the chemist has given us all of the modern methods of
mineral tanning, and without them the modern leather industry
is unthinkable. In the case of vegetable-tanned leather he has
also stepped in, standardized the quality of incoming material
and of outgoing product. In the flour industry the chemist has
learned and taught how to select the proper grain for specific
purposes, to standardize the product, and how to make flour
available for certain specific culinary and food purposes. In
the brewing industry, the chemist has standardized the methods
of determining the quality of incoming material and of outgoing
products, and has assisted in the development of a product of a
quality far beyond that obtaining prior to his entry into that
industry. In the preservation of foods, the chemist made the
fundamental discoveries; up to twenty years ago, however, he
took little or no part in the commercial operations, but now is
almost indispensable to commercial success. In the water supply
of cities, the chemist has put certainty in the place of
uncertainty; he has learned and has shown how, by chemical
methods of treatment and control, raw water of varying quality
can be made to yield potable water of substantially uniform
composition and quality. The celluloid industry and the
nitro-cellulose industry owe their very existence and much of
their development to the chemist. In the glass industry the
chemist has learned and taught how to prepare glasses suitable
for the widest ranges of uses and to control the quality and
quantity of the output. In the pulp and paper industry, the
chemist made the fundamental observations, inventions and
operations and to-day he is in control of all the operations of
the plant itself; to the chemist also is due the cheap
production of many of the materials entering into this
industry, as well as the increased and expanding market for the
product itself.

Sufficient has been presented to show that certain industries
of the United States have been elevated by an infusion of
scientific spirit through the medium of the chemist, and that
manufacturing, at one time entirely a matter of empirical
judgment and individual skill, is more and more becoming a
system of scientific processes. The result is that American
manufacturers are growing increasingly appreciative of
scientific research, and are depending upon industrial
researchers--"those who catalyze raw materials by brains"--as
their pathfinders. It is now appropriate to consider just how
industrialists are taking advantage of the universities and the
products of these.

THE METHODS EMPLOYED IN THE ATTACK OF INDUSTRIAL PROBLEMS[2]

[2] See also Bacon, Science, N. S., 40 (1914), 871.

When an industry has problems requiring solution, these
problems can be attacked either inside or outside of the plant.
If the policy of the industrialist is that all problems are to
be investigated only within the establishment, a research
laboratory must be provided for the plant or for the company.
At present, in the United States, probably not more than one
hundred chemical manufacturing establishments have research
laboratories or employ research chemists, although at least
five companies are spending over $100,000 per year in research.
In Germany, and perhaps also in England, such research
laboratories in connection with chemical industries have been
much more common. The great laboratories of the Badische Anilin
und Soda Fabrik and of the Elberfeld Company are striking
examples of the importance attached to such research work in
Germany, and it would be difficult to adduce any stronger
argument in support of its value than the marvelous
achievements of these great firms.

A frequent difficulty encountered in the employment of
researchers or in the establishment of a research laboratory,
is that many manufacturers have been unable to grasp the
importance of such work, or know how to treat the men in charge
so as to secure the best results. The industrialist may not
even fully understand just what is the cause of his
manufacturing losses or to whom to turn for aid. If he
eventually engages a researcher, he is sometimes likely to
regard him as a sort of master of mysteries who should be able
to accomplish wonders, and, if he can not see definite results
in the course of a few months, is occasionally apt to consider
the investment a bad one and to regard researchers, as a class,
as a useless lot. It has not been unusual for the chemist to be
told to remain in his laboratory, and not to go in or about the
works, and he must also face the natural opposition of workmen
to any innovations, and reckon with the jealousies of foremen
and of various officials.

From the standpoint of the manufacturer, one decided advantage
of the policy of having all problems worked out within the
plant is that the results secured are not divulged, but are
stored away in the laboratory archives and become part of the
assets and working capital of the corporation which has paid
for them; and it is usually not until patent applications are
filed that this knowledge, generally only partially and
imperfectly, becomes publicly known. When it is not deemed
necessary to take out patents, such knowledge is often
permanently buried.

In this matter of the dissemination of knowledge concerning
industrial practice, it must be evident to all that there is
but little cooperation between manufacturers and the
universities. Manufacturers, and especially chemical
manufacturers, have been quite naturally opposed to publishing
any discoveries made in their plants, since "knowledge is
power" in manufacturing as elsewhere, and new knowledge gained
in the laboratories of a company may often very properly be
regarded as among the most valuable assets of the concern. The
universities and the scientific societies, on the other hand,
exist for the diffusion of knowledge, and from their standpoint
the great disadvantage of the above policy is this concealment
of knowledge, for it results in a serious retardation of the
general growth and development of science in its broader
aspects, and renders it much more difficult for the
universities to train men properly for such industries, since
all the text-books and general knowledge available would in all
probability be far behind the actual manufacturing practice.
Fortunately, the policy of industrial secrecy is becoming more
generally regarded in the light of reason, and there is a
growing inclination among manufacturers to disclose the details
of investigations, which, according to tradition, would be
carefully guarded. These manufacturers appreciate the facts
that public interest in chemical achievements is stimulating to
further fruitful research, that helpful suggestions and
information may come from other investigators upon the
publication of any results, and that the exchange of knowledge
prevents many costly repetitions.

INDUSTRIAL FELLOWSHIPS

If the manufacturer elects to refer his problem to the
university or technical school--and because of the facilities
for research to be had in certain institutions, industrialists
are following this plan in constantly increasing numbers--such
reference may take the form of an industrial fellowship and
much has been said and may be said in favor of these
fellowships. They allow the donor to keep secret for three
years the results secured, after which they may be published
with the donor's permission. They also secure to him patent
rights. They give highly specialized training to properly
qualified men, and often secure for them permanent positions
and shares in the profits of their discoveries. It should be
obvious at the outset that a fellowship of this character can
be successful only when there are close confidential relations
obtaining between the manufacturer and the officer in charge of
the research; for no such cooperation can be really effective
unless based upon a thorough mutual familiarity with the
conditions and an abiding faith in the integrity and sincerity
of purpose of each other. It is likely to prove a poor
investment for a manufacturer to seek the aid of an
investigator if he is unwilling to take such expert into his
confidence and to familiarize him with all the local and other
factors which enter into the problem from a manufacturing
standpoint.

THE MELLON INSTITUTE OF INDUSTRIAL RESEARCH[3]

[3] For a detailed description of the Mellon Institute and its
work, see Bacon and Hamor, J. Ind. Eng. Chem., 7 (1915),
326-48.



According to the system of industrial research in operation at
the Mellon Institute of Industrial Research of the University
of Pittsburgh, which is not, in any sense of the word, a
commercial institution, a manufacturer having a problem
requiring solution may become the donor of a fellowship; the
said manufacturer provides the salary of the researcher
selected to conduct the investigation desired, the institute
furnishing such facilities as are necessary for the conduct of
the work.

The money paid in to found a fellowship is paid over by the
institute in salary to the investigator doing the work. In
every case, this researcher is most carefully selected for the
problem in hand. The institute supplies free laboratory space
and the use of all ordinary chemicals and equipment. The
chemist or engineer who is studying the problem works under the
immediate supervision of men who are thoroughly trained and
experienced in conducting industrial research.

At the present time, the Mellon Institute, which, while an
integral part of the University of Pittsburgh, has its own
endowment, is expending over $150,000 annually for salaries and
maintenance. A manufacturer secures for a small
expenditure--just sufficient to pay the salary of the fellow,
as the man engaged on the investigation is called--all the
benefits of an organization of this size, and many have availed
themselves of the advantages, twenty-eight companies
maintaining fellowships at the present time.

Each fellow has the benefit of the institute's very excellent
apparatus, chemical and library equipment--facilities which are
so essential in modern research; and because of these
opportunities and that of being able to pursue post-graduate
work for higher degrees, it has been demonstrated that a higher
type of researcher can be obtained by the institute for a
certain remuneration than can be generally secured by
manufacturers themselves. There is a scarcity of men gifted
with the genius for research, and it requires much experience
in selecting suitable men and in training them to the desirable
degree of efficiency, after having determined the special
qualities required. Important qualifications in industrial
researchers are keenness, inspiration and confidence; these are
often unconsidered by manufacturers, who in endeavoring to
select, say, a research chemist, are likely to regard every
chemist as a qualified scientific scout.

All researches conducted at the Mellon Institute are surrounded
with the necessary secrecy, and any and all discoveries made by
the fellow during the term of his fellowship become the
property of the donor.

When the Mellon Institute moved into its $350,000 home in
February, 1915, the industrial fellowship system in operation
therein passed out of its experimental stage. During the years
of its development no inherent sign of weakness on the part of
any one of its constituent factors appeared; in fact, the
results of the fellowships have been uniformly successful.
While problems have been presented by companies which, upon
preliminary investigation, have proved to be so difficult as to
be practically impossible of solution, there have been so many
other problems confronting these companies that important ones
were found which lent themselves to solution; and often the
companies did not realize, until after investigations were
started, just what the exact nature of their problems was and
just what improvements and savings could be made in their
manufacturing processes.

Fellowships at the Mellon Institute are constantly increasing
in the amounts subscribed by industrialists for their
maintenance and, as well, in their importance. The renewal,
year after year, of such fellowships, as those on baking,
petroleum and ores, goes to show the confidence which
industrialists have in the Mellon Institute. Again, the large
sums of money which are being spent by companies in bringing
small unit plants to develop the processes which have been
worked out in the laboratory, demonstrate that practical
results are being secured.

Where there have been sympathy and hearty cooperation between
the Mellon Institute and the company concerned, the institute
has been able to push through to a successful conclusion large
scale experiments in the factory of the company, which in the
beginning of the fellowship seemed almost impossible: it may be
said that the results of the fellowships at the Mellon
Institute indicate that a form of service to industry has been
established, the possibilities of which no man can say.



A FEW CLASSIC UNKNOWNS IN MATHEMATICS

BY PROFESSOR G. A. MILLER

UNIVERSITY OF ILLINOIS

KING HIERO is said to have remarked, in view of the marvelous
mechanical devices of Archimedes, that he would henceforth
doubt nothing that had been asserted by Archimedes. This spirit
of unbounded confidence in those who have exhibited unusual
mathematical ability is still extant. Even our large city
papers sometimes speak of a mathematical genius who could solve
every mathematical problem that was proposed to him. The
numerous unexpected and far-reaching results contained in the
elementary mathematical text-books, and the ease with which the
skilful mathematics teachers often cleared away what appeared
to be great difficulties to the students have filled many with
a kind of awe for unusual mathematical ability.

In recent years the unbounded confidence in mathematical
results has been somewhat shaken by a wave of mathematical
skepticism which gained momentum through some of the popular
writings of H. Poincare and Bertrand Russell. As instances of
expressions which might at first tend to diminish such
confidence we may refer to Poincare's contention that
geometrical axioms are conventions guided by experimental facts
and limited by the necessity to avoid all contradictions, and
to Russell's statement that "mathematics may be defined as the
subject in which we never know what we are talking about nor
whether what we are saying is true."

The mathematical skepticism which such statements may awaken is
usually mitigated by reflection, since it soon appears that
philosophical difficulties abound in all domains of knowledge,
and that mathematical results continue to inspire relatively
the highest degrees of confidence. The unknowns in mathematics
to which we aim to direct attention here are not of this
philosophical type but relate to questions of the most simple
nature. It is perhaps unfortunate that in the teaching of
elementary mathematics the unknowns receive so little
attention. In fact, it seems to be customary to direct no
attention whatever to the unsolved mathematical difficulties
until the students begin to specialize in mathematics in the
colleges or universities.

One of the earliest opportunities to impress on the student the
fact that mathematical knowledge is very limited in certain
directions presents itself in connection with the study of
prime numbers. Among the small prime numbers there appear many
which differ only by 2. For instance, 3 and 5, 5 and 7, 11 and
13, 17 and 19, 29 and 31, constitute such pairs of prime
numbers. The question arises whether there is a limit to such
pairs of primes, or whether beyond each such pair of prime
numbers there must exist another such pair.

This question can be understood by all and might at first
appear to be easy to answer, yet no one has succeeded up to the
present time in finding which of the two possible answers is
correct. It is interesting to note that in 1911 E. Poincare
transmitted a note written by M. Merlin to the Paris Academy of
Sciences in which a theorem was announced from which its author
deduced that there actually is an infinite number of such prime
number pairs, but this result has not been accepted because no
definite proof of the theorem in question was produced.

Another unanswered question which can be understood by all is
whether every even number is the sum of two prime numbers. It
is very easy to verify that each one of the small even numbers
is the sum of a pair of prime numbers, if we include unity
among the prime numbers; and, in 1742, C. Goldbach expressed
the theorem, without proof, that every possible even number is
actually the sum of at least one pair of prime numbers. Hence
this theorem is known as Goldbach's theorem, but no one has as
yet succeeded in either proving or disproving it.

Although the proof or the disproof of such theorems may not
appear to be of great consequence, yet the interdependence of
mathematical theorems is most marvelous, and the mathematical
investigator is attracted by such difficulties of long
standing. These particular difficulties are mentioned here
mainly because they seem to be among the simplest illustrations
of the fact that mathematics is teeming with classic unknowns
as well as with knowns. By classic unknowns we mean here those
things which are not yet known to any one, but which have been
objects of study on the part of mathematicians for some time.
As our elementary mathematical text-books usually confine
themselves to an exposition of what has been fully established,
and hence is known, the average educated man is led to believe
too frequently that modern mathematical investigations relate
entirely to things which lie far beyond his training.

It seems very unfortunate that there should be, on the part of
educated people, a feeling of total isolation from the
investigations in any important field of knowledge. The modern
mathematical investigator seems to be in special danger of
isolation, and this may be unavoidable in many cases, but it
can be materially lessened by directing attention to some of
the unsolved mathematical problems which can be most easily
understood. Moreover, these unsolved problems should have an
educational value since they serve to exhibit boundaries of
modern scientific achievements, and hence they throw some light
on the extent of these achievements in certain directions.

Both of the given instances of unanswered classic questions
relate to prime numbers. As an instance of one which does not
relate to prime numbers we may refer to the question whether
there exists an odd perfect number. A perfect number is a
natural number which is equal to the sum of its aliquot parts.
Thus 6 is perfect because it is equal to 1 + 2 + 3, and 28 is
perfect because it is equal to 1 + 2 + 4 + 7 + 14. Euclid
stated a formula which gives all the even perfect numbers, but
no one has ever succeeded in proving either the existence or
the non-existence of an odd perfect number. A considerable
number of properties of odd perfect numbers are known in case
such numbers exist.

In fact, a very noted professor in Berlin University developed
a series of properties of odd perfect numbers in his lectures
on the theory of numbers, and then followed these developments
with the statement that it is not known whether any such
numbers exist. This raises the interesting philosophical
question whether one can know things about what is not known to
exist; but the main interest from our present point of view
relates to the fact that the meaning of odd perfect number is
so very elementary that all can easily grasp it, and yet no one
has ever succeeded in proving either the existence or the
non-existence of such numbers.

It would not be difficult to increase greatly the number of the
given illustrations of unsolved questions relating directly to
the natural numbers. In fact, the well-known greater Fermat
theorem is a question of this type, which does not appear more
important intrinsically than many others but has received
unusual attention in recent years on account of a very large
prize offered for its solution. In view of the fact that those
who have become interested in this theorem often experience
difficulty in finding the desired information in any English
publication, we proceed to give some details about this theorem
and the offered prize. The following is a free translation of a
part of the announcement made in regard to this prize by the
Konigliche Gesellschaft der Wissenschaften, Gottingen, Germany:

On the basis of the bequest left to us by the deceased Dr. Paul
Wolskehl, of Darmstadt, a prize of 100,000 mk., in words, one
hundred thousand marks, is hereby offered to the one who will
first succeed to produce a proof of the great Fermat theorem.
Dr. Wolfskehl remarks in his will that Fermat had maintained
that the equation

x <superscript Greek 1> + y <superscript Greek 1> =
z <superscript Greek 1>

could not be satisfied by integers whenever <Greek l> is an odd
prime number. This Fermat theorem is to be proved either
generally in the sense of Fermat, or, in supplementing the
investigations by Kummer, published in Crelle's Journal, volume
40, it is to be proved for all values of <Grrek 1> for which it
is actually true. For further literature consult Hibert's
report on the theory of algebraic number realms, published in
volume 4 of the Jahreshericht der Deutschen
Mathernatiker-Vereinigung, and volume 1 of the Encyklopadie der
mathematischen Wissenschaften.

The prize is offered under the following more particular
conditions.

The Konigliche Gesellschaft der Wissenschaften in Gottingen
decides independently on the question to whom the prize shall
be awarded. Manuscripts intended to compete for the prize will
not be received, but, in awarding the prize only such
mathematical papers will be considered as have appeared either
in the regular periodicals or have been published in the form
of monographs or books which were for sale in the book-stores.
The Gesellschaft leaves it to the option of the author of such
a paper to send to it about five printed copies.

Among the additional stipulations it may be of interest to note
that the prize will not be awarded before at least two years
have elapsed since the first publication of the paper which is
adjudged as worthy of the prize. In the meantime the
mathematicians of various countries are invited to express
their opinion as regards the correctness of this paper. The
secretary of the Gesellschaft will write to the person to whom
the prize is awarded and will also publish in various places
the fact that the award has been made. If the prize has not
been awarded before September 13, 2007, no further applications
will be considered.

While this prize is open to the people of all countries it has
become especially well known in Germany, and hundreds of
Germans from a very noted university professor of mathematics
to engineers, pastors, teachers, students, bankers, officers,
etc., have published supposed proofs. These publications are
frequently very brief, covering only a few pages, and usually
they disclose the fact that the author had no idea in regard to
the real nature of the problem or the meaning of a mathematical
proof. In a few cases the authors were fully aware of the
requirements but were misled by errors in their work. Although
the prize was formally announced more than seven years ago no
paper has as yet been adjudged as fulfilling the conditions.

It may be of interest to note in this connection that a
mathematical proof implies a marshalling of mathematical
results, or accepted assumptions, in such a manner that the
thing to be proved is a NECESSARY consequence. The
non-mathematician is often inclined to think that if he makes
statements which can not be successfully refuted he has carried
his point. In mathematics such statements have no real
significance in an attempted proof. Unknowns must be labeled as
such and must retain these labels until they become knowns in
view of the conditions which they can be proved to satisfy. The
pure mathematician accepts only necessary conclusions with the
exception that basal postulates have to be assumed by common
agreement.

The mathematical subject in which the student usually has to
contend most frequently with unknowns at the beginning of his
studies is the history of mathematics. The ancient Greeks had
already attempted to trace the development of every known
concept, but the work along this line appears still in its
infancy. Even the development of our common numerals is
surrounded with many perplexing questions, as may be seen by
consulting the little volume entitled "The Hindu-Arabic
Numerals," by D. E. Smith and L. C. Karpinski.

The few mathematical unknowns explicitly noted above may
suffice to illustrate the fact that the path of the
mathematical student often leads around difficulties which are
left behind. Sometimes the later developments have enabled the
mathematicians to overcome some of these difficulties which had
stood in the way for more than a thousand years. This was done,
for instance, by Gauss when he found a necessary and sufficient
condition that a regular polygon of a prime number of sides can
be constructed by elementary methods. It was also done by
Hermite, Lindemann and others by proving that epsilon and rho
are transcendental numbers. While such obstructions are thus
being gradually removed some of the most ancient ones still
remain, and new ones are rising rapidly in view of modern
developments along the lines of least resistance.

These obstructions have different effects on different people.
Some fix their attention almost wholly on them and are thus
impressed by the lack of progress in mathematics, while others
overlook them almost entirely and fix their attention on the
routes into new fields which avoid these difficulties. A
correct view of mathematics seems to be the one which looks at
both, receiving inspiration from the real advances but not
forgetting the desirability of making the developments as
continuous as possible. At any rate the average educated man
ought to know that there is no mathematician who is able to
solve all the mathematical questions which could be proposed
even by those having only slight attainments along this line.



THE ABORIGINAL ROCK-STENCILLINGS OF NEW SOUTH WALES

BY DR. CHAS. B. DAVENPORT

COLD SPRING HARBOR, N. Y.

IN a number of places in eastern Australia curious aboriginal
markings are found on the faces of the sandstone cliffs. A good
idea of them is given by the photographs. These came from
Wolgan Gap near Wallerang in the Blue Mountain region of New
South Wales. They are found on overhanging rocks that have
served as shelters or camping places for the aborigines and
which doubtless have protected their works of art.

These stencillings are made by a sort of spatter work,
something like that in vogue a generation ago in this country,
using leaves, etc., as forms. The rocks at Wolgan Gap are a
coarse sandstone stained almost black by an iron oxide derived
from included bands of ironstone. These black surfaces were
selected by the artists. Nearby in the rock is a band of shale
which had disintegrated at its exposed edge to a white powder.
The native artist put some of this white powder in his mouth,
placed his hand or foot upon the rock, and blew the moistened
powder upon and around his outstretched fingers or toes. When
he removed them they were outlined on the rock. Since the
sandstone is coarse and deeply pitted, the moist powder was
blown into minute cavities where it has remained despite the
erosive activities of some generations. The presence of the
powder is shown on the photographs as a sort of halo around the
object. The hands are either right or left, and, in some cases,
both hands seem to have been stencilled at once. Sometimes the
whole arm and hand are stencilled together, and in one of the
photographs a boomerang is shown. The age of these stencils is
not known. They were first discovered at Wolgan Gap about sixty
years ago, but others have been known for a longer time, for
instance, those at Greenwich, Parametta River, near Sydney.

The significance of these stencillings has been the subject of
some controversy. The natives may have been induced to make
them as boys carve their names on benches or even rocks. The
materials for making the stencillings were present and, the
example once having been set, others would emulate it. It is
interesting that similar stencillings of the hands were made by
cave men on the walls of some of the European caves, as, for
instance, those of Aurignac in southern France. Evidently
spatter work is no modern pastime.



THE PROGRESS OF SCIENCE

SUBSTITUTES FOR WAR

THIS war, beyond measure disastrous to civilization, is a trial
also of our democracy. We may hope that it is an old-world war
and an old-men's war, repugnant to the genius of our newer
life. The statements of some of our public men and the contents
of some of our newspapers can not be read without
discouragement. But it is also true that there has perhaps not
appeared a cartoon in any American newspaper tending to glorify
war, and no legislation has so far been enacted in preparation
for war. There is good reason to believe that the people have
not been infected by the contagion of blood.

As Professor Patrick argued in a recent issue of the Monthly,
man is by genetic inheritance a fighting and a playing animal,
not an animal delighting in steady work. The ape and the tiger
will be exterminated elsewhere in nature before they will be
suppressed in man. It is a slow process, but surely proceeding.

The writer of this note has determined the proportion of each
century in which the leading nations have been engaged in war.
The curve thus found has no great reliability; for it does not
take into account the percentages of the peoples concerned, but
its course clearly indicates that even under circumstances as
they have been, wars will come to an end. And there is good
reason to believe that the newer condition--universal education
and universal suffrage, democratic control, improved economic
conditions of living for the people, the scientific
attitude--will tend to bend the curve more rapidly toward the
base line of permanent "peace on earth and good will to men."

While man has inherited instincts which exhibit themselves in
playing and fighting, the same instincts may by social control
be diverted to playing the games of art or science, to fighting
disease and vice. It is rarely wise or feasible to attempt to
suppress instincts; they should be directed so as to provide
desirable conduct. Loyalty to family, to group, to neighborhood
and to nation can not be lightly cast away for an abstract
cosmopolitanism. But it can be expressed otherwise than by
seizing everything in sight by cunning or by violence.

William James, the great psychologist, in one of his brilliant
essays published in The Popular Science Monthly for October,
1910, tells us that history is a bath of blood; we inherit the
war-like type; our ancestors have bred pugnacity into our bone
and marrow; showing the irrationality and horror of war does
not prevent it; but a moral equivalent can be found by
enlisting an army to toil and suffer pain in doing the hard and
routine work of the world. It is doubtful, however, if the
"gilded youths" to whom James refers would accept
"dish-washing, clothes-washing and window-washing,
road-building and tunnel-making, foundries and stoke-holes," as
a substitute for war, and for the great mass of the people
there is more than enough of these things. It is to escape from
them that we seek excitement and adventure, intoxication by
drugs and war.

Professor Cannon, of Harvard University, proposes international
football and other athletic contests as substitutes for war.
The adrenal glands, whose secretions excite the combative and
martial emotions, must function, and their activity, he argues,
can be directed in this way. Mr. Bryan has just now made the
proposal that we build six great national roads by which armies
might be collected for defence; the secretary of the navy has
founded a Naval Inventions Board; the postmaster general has
suggested that aeroplanes be used to deliver mail in order that
we may have an aerial corps ready for service. There may be an
element of the absurd in some of these proposals, as there
would be in using submarines to catch cod fish, so that there
might be practise in building and managing such crafts for
peaceful pursuits. There is, however, psychological
justification for aiming to direct the emotions so that their
discharge is not destructive, but of benefit to the nation and
to the world. Such would be the development of our national
resources, the construction of railways, roads, waterworks and
the like; social and political reforms; progress in the care of
public health, in education and in scientific research. It is
proposed that the next congress should spend half a billion
dollars on the army and navy. It is possible that on a
plebiscite vote, exactly under existing conditions, a majority
would vote to make the department of war a department of public
works, military defence being only one of its functions, and to
spend the sum proposed on public works useful in case of war,
but not an incitement to war.

NATIONAL WEALTH AND PUBLIC INDEBTEDNESS

WHILE the lives and the wealth of the European nations are
being sacrificed on a scale hitherto unparalleled, it is well
in the interests of those nations, as well as of our own, that
we conserve the lives and wealth of our own people. The
greatest wealth of a nation is its children, its productive
workers, its scientific men and other leaders, its accumulated
knowledge and social traditions. These are immeasurable, but
the Bureau of the Census has recently prepared a report on the
material wealth and indebtedness, according to which it is
estimated that the total value of all classes of property in
the United States, exclusive of Alaska and the insular
possessions, in 1912, was $187,739,000,000, or $1,965 per
capita. This estimate is presented merely as the best
approximation which can be made from the data available and as
being fairly comparable with that published eight years ago.
The increase between 1904 and 1912 was 75 per cent., for the
total amount and 49 per cent. for the per capita. Real estate
and improvements, including public property, alone constituted
$110,677,000,000, or 59 per cent. of the total, in 1912. The
next greatest item, $16,149,000,000, was contributed by the
railroads; and the third, $14,694,000,000, represented the
value of manufactured products, other than clothing and
personal adornments, furniture, vehicles and kindred property.

The net public-indebtedness in 1913 amounted to $4,850,461,000.
This amount was made up as follows: National debt,
$1,028,564,000, or $10.59 per capita; state debt, $345,942,000,
or $3.57 per capita; county debt, $371,528,000, or $4.33 per
capita; and municipal debt, $2,884,883,000, or $54.27 per
capita. Thus the average urban citizen's share of the net
federal, state, county and municipal debt combined was $72.76;
and the average rural citizen's share of the net federal, state
and county debt combined was $18.49.

The total federal debt in 1910 was $2,916,205,000, of which
amount $967,366,000 was represented by bonds, $375,682,000 by
non-interest-bearing debt (principally United States notes or
"greenbacks"), and $1,573,157,000 by certificates and notes
issued on deposits of coin and bullion. Against this
indebtedness there was in the treasury $1,887,641,000 in cash
available for payment of debt, leaving the net national
indebtedness at $1,028,564,000, or $10.59 per capita. The
increase in the net indebtedness between 1902 and 1913 amounted
to 6 per cent., but for the per capita figure there was a
decrease of 13 per cent. The burden due to the national debt is
thus very light in comparison with that imposed by the
indebtedness of other great nations.

The state debt, however, rests still more easily on the
shoulders of the average citizen, being only one third as great
as that of the nation. The total state indebtedness in 1913 was
$422,797,000, and the net debt--that is, the total debt less
sinking-fund assets--was $345,942,000, or $3.57 per capita. The
net debt increased by 44.5 per cent. between 1902 and 1913, and
the per capita net debt by 18 per cent.

The total county debt in 1913 amounted to $393,207,000, of
which amount $371,528,000, or $4.33 per capita, was net debt.
The net indebtedness increased by 89 per cent. between 1902 and
1913, and the per capita net indebtedness by 55 per cent. By
far the greatest item of indebtedness in this country is that
of municipalities. This amounted in 1913 to an aggregate of
$3,460,000,000, of which $2,884,883,000, or $54.27 per capita,
represented net indebtedness. The rate of increase in net
indebtedness between 1902 and 1913 was 114 per cent.

While the nations of Europe are involving themselves in the
toils of debts, we should use our vast surplus wealth to pay
the national, state and municipal debts, even those contracted
for public improvements. We save every year about $100 for each
adult and child of the country and waste about an equal sum. It
would be well if this wealth could be invested for the benefit
of each, and education and scientific research are the most
productive of all investments.

PAPUA, WHERE THE STONE-AGE LINGERS

BY DR. ALFRED GOLDSBOROUGH MAYER

WITH their undaunted spirit for braving the wilds, the English
entered New Guinea in 1885. For centuries the great island had
remained a mere outline upon the map the fever-haunted glades
of its vast swamps and the broken precipices of its mountain
ranges having defied exploration, more than the morose and
savage character of its inhabitants. Even in the summer of
1913, Massy Baker the explorer, discovered a lake probably 100
miles or more in shore-line, which had remained hidden in the
midst of the dark forests of the Fly and Strickland River
regions, and here savages still in the stone age, who had never
seen a white man, measured the potency of their weapons against
the modern rifle.

To-day there are vast areas upon which the foot of the white
man has not yet trodden, and of all the regions in the tropical
world New Guinea beckons with most alluring fascination to him
to whom adventure is dearer than life.

Far back in the dawn of European exploration, the Portuguese
voyager Antonio de Abreu, may have seen the low shores of
western New Guinea, but it is quite certain that sixteen years
later, in 1527, Don Jorge de Meneses cruised along the coast
and observed the wooly-headed natives whom he called "Papuas."
The name "New Guinea" was bestowed upon the island by the
Spanish captain, Ynigo Ortz de Retes, in 1515, when he saw the
negroid natives of its northern shores.

Then there came and passed some of the world's greatest
navigators. Torres wandering from far Peru, to unknowingly
discover the strait which bears his name; Dampier, the
buccancer-adventurer, and, in 1768, the cultured, esthetic
Bougainville, who was enraptured by the beauty of the deep
forest-fringed fjords of the northeastern coast. Cook, greatest
of all geographers, mapped the principal islands and shoals of
the intricate Torres Strait in 1770; and a few years later came
Captain Bligh, the resourceful leader of his faithful few,
crouching in their frail sail boat that had survived many a
tempest; since the mutineers of the Bounty had cast them adrift
in the mid-Pacific. In the early years of the nineteenth
century the scientifically directed Astrolabe arrived, under
the command of Dumont D'Urville, and, later, Captain Owen
Stanley in the Rattlesnake, with Huxley as his zoologist, Then,
in 1858, came Alfred Russel Wallace, the codiscoverer of
Darwinism, who, by the way, is said to have been the first
Englishman who ever actually resided in New Guinea.

The daring explorers and painstaking surveyors came and went,
but the great island remained a land of dread and mystery,
guarded by the jagged reefs of its eastern shores, and the
shallow mud flats, stretching far to sea-ward beyond the mouths
of the great rivers of its southern coast. So inaccessible was
Papua that even the excellent harbor of Port Moresby, the site:
of the present capital, was not discovered until 1873. One has
but to stifle for a while in the heavy air that flows lifeless
and fetid over the lowlands as if from a steaming furnace, or
to scent the rank odors of the dark swamps, where for centuries
malaria must linger, to appreciate the reason for the
long-delayed European settlement of the country. But those who
blaze the path of colonial progress are not to be deterred by
temperatures or smells; let us remember that Batavia, "the
white man's graveyard," is now one of the world's great
commercial centers; and Jamaica, the old fever camp of the
British army, is now a health resort for tourists.

Papua, the land of the tired eyes and the earnest face, of the
willing spirit and the weary body, waning as strength fails
year by year in malaria and heat, the land wherein the heart
aches for the severed ties of wife and home; its history has
hardly yet begun, but the reward of generations of heroism will
be the conquest of another empire where England's high
standards of freedom are to he raised anew. A victory of peace
it is to be, as noble as any yet achieved in war; and great
through its death roll, and forgotten though the workers be,
the fruits of their labors will bless that better world Great
Britain is preparing for those of ages yet to come.

There are great resources in Papua with its area of 90,500
square miles. Untrodden forests where the dark soil moulders
beneath the everlasting shade; swamps bearing a harvest of
thousands of sago and nipa palms, and mountains in a riot of
contorted peaks rising to a height of 13,200 feet in the Owen
Stanley range.

It is still a country of surprises, as when petroleum fields,
probably 1,000 square miles in area, were discovered only about
four years ago along the Vailala River, the natives having
concealed their knowledge of the bubbling gas springs through
fear of offending the evil spirits of the place. It is evident
that although the country has been merely glanced over, there
are both agricultural and mineral resources of a promising
nature in Papua. It remains but for modern medicine to
over-come the infections of the tropics for the region to rise
into prominence as one of the self-supporting colonies of the
British empire.

The early history of British occupation centers around the
striking personality of James Chalmers, the great-hearted,
broad-minded, missionary, one of the most courageous who ever
devoted his life to extending the brotherhood of the white
man's ideals. Chafing, as a young man, under the petty
limitations of his mission in the Cook Islands, he sought New
Guinea, as being the wildest and most dangerous field in the
tropical Pacific. Here, for twenty-five years, he devoted his
mighty soul to the work of introducing the rudiments of
civilization and Christianity to the most sullen and dangerous
savages upon earth. Scores of times his life hung in the
balance of native caprice; wives and friends died by his side,
victims to the malignant climate and to native spears, while he
seemed to possess a charmed life; until, true to his
prediction, he was murdered by the cannibals of Dopina at the
mouth of the Fly River in 1901.

Hundreds of scattered tribes had learned to revere their great
leader "Tamate," as they called him, who brought peace and
prosperity to his followers. Yet a danger to Papua that he
himself foresaw and did all in his power to avert came as a
result of the introduction of the very civilization of which he
was the champion, for with peace came new wants that the most
unscrupulous of traders at once sought to supply at prices
ruinous to the social and moral welfare of the natives.

Also, the proximity of Queensland threatened to become a
menace; for Chalmers himself was well aware of the dark history
of the "blackbird trade" wherein practical slavery was forced
upon the indentured laborers, lured from their island homes to
toil as hopeless debtors upon the Australian plantations. A
government of the natives for the native interests he desired;
not one administered from the Australian mainland in the
interest of alien whites. The hopes of Chalmers were only
partially realized, for Papua is still only a territory of
Australia.

In most respects this condition appears to be unfortunate. The
crying needs of a new country are usually peculiarly local and
not likely to be appreciated by a distant ruling power.
Moreover, Australia is itself an undeveloped land and requires
too large a proportion of its own capital for expansion at home
to be a competent protector of a colony across the sea. One
feels that Papuan development might have proceeded with greater
smoothness had the colony been more directly under the British
empire, rather shall an Australian dependency.

The strategic necessity that Australia should command both the
northern and the southern shores of Torres Straits might still
have been secured without the sacrifice of any important
initiative in matters of government upon the part of Papua.

The cardinal evil that Chalmers feared has, however, been
averted. The natives still own 97 1/2 per cent. of the entire
land area, and wise laws guard them in this precious
possession, and aim to protect them from all manner of unjust
exploitation. It is much to the credit of the government that
the cleanest native villages and the most healthy, ambitious
and industrious tribes, are those nearest the white
settlements. Contact between the races has resulted in the
betterment, not in the degradation, of the Papuan natives.

The touch of a master hand is apparent in a multitude of
details in managing the natives of Papua; and it is of interest
to see that in broad essentials the plan of government is
adapted from that which the English have put to the test of
practice in Fiji; the modifications being of a character
designed to meet the conditions peculiar to Melanesia, wherein
the chiefs are relatively unimportant in comparison with their
role in the social systems of the Polynesians and Fijians.
Foremost in the shaping of the destiny of Papua stands the
commanding figure of Sir William Macgregor, administrator and
lieutenant governor from 1888 to 1898. As a young man Macgregor
was government physician in Fiji, where he became prominent not
only as a competent guardian of the health of the natives, but
as a leader in the suppression of the last stronghold of
cannibalism along the Singatoka River. In Papua his tireless
spirit found a wide field for high endeavor, and upon every
department of the government one finds to-day the stamp of his
powerful personality. Nor did he remain closeted in Port
Moresby, a stranger to the races of his vast domains, for over
the highest mountains and through the densest swamps his
expeditions forced their way; the Great Governor always in the
van. It was thus that he conquered the fierce Tugeri of the
Dutch border, who for generations had been the terror of the
coasts; and wherever his expeditions passed, peace followed,
and the law of the British magistrate supplanted the caprice of
the sorcerer.

But his hardest fight was not with the mountain wilds or the
malarious morasses. It was to secure from the powerful ones of
his own race the privileges of freemen for the natives of
Papua.

In his youth he had seen the blessings that came with the
advent of British rule in Fiji; and here, in broad New Guinea,
upon a vaster scale, he strove to make fair play the dominant
note in the white man's treatment of a savage race.

Arrayed against Chalmers and Macgregor were conservatism and
suspicion founded in ancient precedent, and a commercial
avarice that saw in native exploitation the readiest means to
convert New Guinea into a "white man's country." Aversion there
was also in high places to embarking upon a possibly fruitless
experiment, involving generations of labor and expense for a
remote and uncertain harvest. Chalmers and Macgregor, however,
through the force of their high convictions and the wisdom of
their wide experience, won the great fight for fairness; for
civilization's cardinal victories are those, not of the
soldier, but of the civil servant who dares risk his reputation
and his all for those things he deems just and generous; and
when Papua comes to erect statues to her great leaders, those
of these two patriots must surely occupy the highest places, as
champions of the liberties of the weak. The noble policy of
Macgregor is still, and let us hope it long may be, the keynote
of the administration in Papua, which to-day is being ably
carried forward under the great governor's disciple, the
Honorable John H. P. Murray.

The proclamation given by Captain Erskine in 1884 declared that
a British Protectorate had become essential for the
safeguarding of the lives and property of the natives of New
Guinea and for the purpose of preventing the occupation of the
country by persons whose proceedings might lead to injustice,
strife and bloodshed, or whose illegitimate trade might
endanger the liberties and alienate the lands of the natives.

It is, however, one thing for a government to declare its
altruistic intentions, but often quite another to carry them
into effect.

In Papua, every effort has been made to prevent robbery of the
natives by unscrupulous whites. The natives are firmly secured
in the possession of their lands, which they can neither sell,
lease nor dispose of, except to the government itself. Thus the
natives and the government are the only two landlords in the
country. To acquire land in Papua, the European settler must
rent it from the government, for he is not permitted to acquire
fee simple rights. The whites are thus tenants of the
government, and are subject to such rules and regulations as
their landlord may decree. The tenant is, however, recognized
as the creator and owner of any improvements he may erect upon
the land, and, at the expiration of his lease, the government
undertakes to pay him a fair compensation for such
improvements, provided he has lived up to the letter of
regulations respecting his tenure.

For agricultural land a merely nominal rental is demanded,
ranging from nothing for the first ten years to a final maximum
of six pence per acre; yet this system has had the effect of
retarding European settlement, for, although its area is twice
that of Cuba, Papua had but 1,064 whites in 1912, and only one
one hundred and seventy-fourth of the territory is held under
lease.

Men of the type who can conquer the primeval forests and create
industries prefer to own their land outright, and are apt to
resent the restrictions of complex government regulations,
however wisely administered. Socialism, while it may in some
measure be desirable in old and settled communities, serves but
to dull that sense of personal freedom which above all spurs
the pioneer onward to success in a wild and dangerous region.

Possibly in the end, the government may find it advantageous to
permit certain lands to be acquired by Europeans, in fee
simple; for until this is done the settlement of the country
must proceed with extreme slowness. Moreover, mere tenants
owning nothing but their improvements, and even these being
subject to government appraisement, may be unduly tempted to
drain, rather than to develop, the resources of the land they
occupy.

But the chief aim of the Papuan government is to introduce
civilization among the natives, and a slow increase in the
European population is of primary necessity to the
accomplishment of this result.

At present the natives are not taxed, the chief sources of
revenue being derived from the customs duties upon imports, the
bulk of which are consumed by the Europeans, and this source of
income is supplemented by an annual grant of about 25,000
pounds from the Australian Commonwealth, but, due to the duties
upon food and necessities, the cost of living is higher than it
should be in a new country.

Judging, however, from the experience of the English in Fiji
and of the Dutch in Java, the natives would be benefited rather
than oppressed by a moderate poll tax to be paid in produce,
thus developing habits of industry, and in some measure
offsetting the evil effects of that insidious apathy which
follows upon the sudden abolition of native warfare.

Every effort should also he made to encourage and educate the
Papuans in the production and sale of manufactured articles.
One must regret the loss of many arts and crafts among the
primitive peoples of the Pacific, which, if properly fostered
under European protection to insure a market and an adequate
payment for their wares, would have been a source of revenue
and a factor of immeasurable import in developing that self
respect and confidence in themselves which the too sudden
modification of their social and religious Systems is certain
to destroy. The ordinary mission schools are deficient in this
respect, devoting their major energies to the "three R's" and
to religious instruction, and, while it is pleasing to observe
a boy whose father was a cannibal extracting cube roots, one
can not but conclude that the acquisition of some money-making
trade would be more conducive to his happiness in after life.

It is not too much to say that the chief problem in dealing
with an erstwhile savage race is to overcome the universal loss
of interest and decline in energy which inevitably follows upon
the development of that semblance of civilization which is
enforced with the advent of the white man. The establishment of
manual training schools wherein arts and crafts which may be
profitably practiced by the natives as life-professions, is a
first essential to the salvation of the race. These schools
should and would in no manner interfere with the religious
teaching received from missionaries, but would indeed be a most
potent factor in the spread of true Christianity among the
natives. Whether Christianity be true or false does not affect
the case, for the natives are destined to be dominated by
Christian peoples, and it primarily essential that they should
understand at least the rudiments of Christian ideals and
behavior.

The realization of the importance of training them to the
pursuit of useful arts and trades, which would enable the
natives to become self-supporting in the European sense, has
been perceived by certain thinkers among the missionaries
themselves, and in certain regions efforts are being made the
success of which should revolutionize our whole method of
dealing with the problem of introducing civilization among a
primitive people.

Keep their minds active and their hands employed in
self-supporting work and their morals and religion will safely
fall into accord with Christian standards.

Up to the present native education has been left to the devoted
efforts of the missionaries, who have more than 10,000 pupils
under their charge, but the time is coming when the government
should cooperate in establishing trade schools wherein crafts,
providing life-vocations to the natives, may be taught.

There may be more than 275,000 natives in Papua, but, due to
lack of knowledge of the country, the actual number is unknown.

Among the mountain fastnesses, defending themselves in
tree-houses, one finds a frizzly-headed black negrito-like race
hardly more than five feet in height. These are probably
remnants of the "pigmy" pre-Dravidian or Negrito-Papuan
element, which constituted the most ancient inhabitants of the
island and who long ago were driven inland from the coveted
coast.

The burly negroid Papuans of the Great River deltas of western
Papua differ widely from the lithe, active, brown-skinned,
mop-headed natives of the eastern half of the southern coast;
and Professors Haddon and Seligmann have decided that in
eastern New Guinea many Proto-Polynesian, Melanesian and
Malayan immigrants have mingled their blood with that of the
more primitive Papuans. Thus there are many complexly
associated ethnic elements in New Guinea, and often people
living less than a hundred miles apart can not understand one
another; in fact, each village has its peculiar dialect. Social
customs and cultural standards in art and manufacture vary
greatly from the same cause, and each tribe has some remarkable
individual characteristics. In the Fly-River region, the
village consists of a few huge houses with mere stalls for the
families, which crowd for defence under the shelter of a single
roof. Along the southern side of the eastern end of the island,
however, each family has its own little thatched hut, and these
are often built for defense upon piling over the sea, reminding
one of the manner of life of the prehistoric Swiss-lake
dwellers.

Nearly 12,000 natives are at present employed by the whites as
indentured laborers in Papua, their terms of service ranging
from three years, upon agricultural work, to not more than
eighteen months in mining. Their wages range from about $1.50
to $5.00 per month, and all payments must be made in the
presence of a magistrate and in coin or approved bank notes.

At every turn both employer and employed are wisely
safeguarded; the native suffering imprisonment for desertion,
and the employer being prohibited from getting the blacks into
debt, or from treating them harshly or unjustly. Their
enlistment must be voluntary and executed in the presence of a
magistrate, and, after their term of service, the employer is
obliged to return them to their homes.

One is impressed with the many manifestations of a fair degree
of efficiency on the part of the native laborers, who are
really good plantation hands and resourceful sailors. In fact,
trade has always been practiced to a considerable extent by the
shore tribes, the pottery of the eastern end of the coast being
annually exchanged for the sago produced by the natives of the
Fly River Delta. It is a picturesque sight to see the large
lakatois, or trading canoes, creeping along in the shadow of
the palm-fringed shores under the great wall of the mountains,
the lakatoi consisting of a raft composed of six or more canoes
lashed together side by side, and covered by a platform which
bears a thatched hut serving to house the sailors and their
wares. The craft is propelled by graceful crescent-shaped
lateen sails of pandanus matting and steered by sweeps from the
stern. Trading voyages of hundreds of miles are often
undertaken, the lakatois starting from the east at the waning
of the southeast trade wind in early November and returning a
month or two later in the season of the northwest monsoon.

The Papuan is both ingenious and industrious when working in
his own interest, and with tactful management he becomes a
faithful and fairly efficient laborer. Perhaps the most serious
defect in the present system of employment in Papua is the
usually long interval between payments. The natives are not
paid at intervals of less than one month and, often, not until
the expiration of their three-year term of service. With almost
no knowledge of arithmetic and possessed of a fund which seems
large beyond the dreams of avarice, he is practically certain
to be cheated by the dishonest tradesmen who flock vulture-like
to centers of commercial activity. This evil might be in large
measure prevented were the natives to be paid at monthly
intervals, for they would then gradually become accustomed to
the handling of money and would gain an appreciation of its
actual value.

Generations must elapse before more than a moderate degree of
civilization is developed in Papua, but the foundations are
being surely and conservatively laid, and already in the
civilized centers natives respect and loyally serve their
British friends and masters.

In common with many another British colony, the safeguard of
Papua lies not in the rifles of the whites, but in the loyal
hearts of the natives themselves, and in Papua, as in Fiji, the
native constabulary under the leadership of a mere handful of
Europeans may be trusted to maintain order in any emergency. As
Governor Murray truly states in his interesting book "Papua, or
British New Guinea," the most valuable asset the colony
possesses is not its all but unexplored mineral wealth or the
potential value of its splendid forests and rich soil, but it
is the Papuans themselves, and let us add that under the
leadership of the high-minded, self-sacrificing and
well-trained civil servants of Great Britain the dawn of Papuan
civilization is fast breaking into the sunlight of a happiness
such as has come to but few of the erstwhile savage races of
the earth.

Without belittling the nobility of purpose or disregarding the
self-sacrificing devotion of the missionary for his task, let
us also grant to the civil servant his due share of praise. His
duty he also performs in the dangerous wilds of the earth;
beset with insidious disease, stifling in unending heat, exiled
from home and friends, with suspicious savages around him, he
labors with waning strength in that struggle against climate
wherein the ultimate ruin of his body is assured. Yet in his
heart there lives, growing as years elapse, the English
gentleman's ideal of service, and for him it is sufficient
that, though he is to be invalided and forgotten even before he
dies, yet his will have been one of those rare spirits who have
extended to the outer world his mother country's ideal of
justice and fair play.



CONTACT ELECTRIFICATION AND THE ELECTRIC CURRENT

BY PROFESSOR FERNANDO SANFORD

STANFORD UNIVERSITY

IN a previous paper in this journal, entitled "The Discovery of
Contact Electrification" (November, 1913), it was shown that
the production of electric charges by the mere contact of two
dissimilar metals was first discovered by Rev. Abraham Bennett,
in 1789, and that it was verified by a different method by
Tiberius Cavallo, in 1795. Meantime, in 1791, Dr. Galvani
discovered the twitching of a frog's muscle, due to electrical
stimulus. Galvani's discovery was described by himself as
follows:[1]

[1] Translation from "Makers of Electricity," p 143.

'I had dissected a frog and had prepared it, as in Figure 2 of
the fifth plate, and had placed it upon a table on which there
was an electric machine, while I set about doing certain other
things. The frog was entirely separated from the conductor of
the machine, and indeed was at no small distance away from it.
While one of those who were assisting me touched lightly and by
chance the point of his scalpel to the internal crural nerves
of the frog, suddenly all the muscles of its limbs were seen to
be so contracted that they seemed to have fallen into tonic
convulsions. Another of my assistants, who was making ready to
take up certain experiments in electricity with me, seemed to
notice that this happened only at the moment when a spark came
from the conductor of the machine. He was struck by the novelty
of the phenomenon, and immediately spoke to me about it, for I
was at the moment occupied with other things and mentally
preoccupied. I was at once tempted to repeat the experiment, so
as to make clear whatever might be obscure in it. For this
purpose I took up the scalpel and moved its point close to one
or the other of the crural nerves of the frog, while at the
same time one of my assistants elicited sparks from the
electric machine. The phenomenon happened exactly as before.
Strong contractions took place in every muscle of the limb, and
at the very moment when the sparks appeared, the animal was
seized as it were with tetanus.'

Following this original observation, Galvani made a great many
experiments on the effect of electric stimulus upon the nerves
of frogs and other animals. He found that the twitching of the
frog's muscles could be produced by atmospheric electricity,
both at the time of lightning and at other times when no
lightning was visible. During these investigations he observed
that when the legs of the frog were suspended from an iron
railing by a hook through the spinal cord, and when this hook
was of some other metal than iron, the muscles would twitch
whenever the feet touched the iron railing. He tried out a
number of pairs of metals, and found that when the nerve was
touched by one metal and the muscle or another point on the
nerve was touched by another metal and the two metals were then
brought into contact or were connected through another metal or
through the human body, the muscles would contract as they
would when stimulated by electricity.

Galvani concluded that the contraction in this case, as in the
earlier experiments, was produced by an electric stimulation,
and since the metals seemed to him to serve merely as the
conductors of the electric discharge, he concluded that the
source of the electricity must be in the tissues of the animal
body. This seemed all the more probable since it was known that
certain fishes and an electric eel were capable of giving
violent electric shocks. This electricity of the eels and
fishes had been named animal electricity, and Galvani concluded
that all animals were capable of producing this electricity in
the tissues of their bodies.

He believed this electricity was to be found in various parts
of the body, but that it was especially collected in the nerves
and muscles. The especial property of this animal electricity
seemed to be that it discharged from the nerves into the
muscles, or in the contrary direction, and that to effect this
discharge it would take the path of least resistance through
the metal conductor or through the human body. Since during
this discharge the muscle was caused to contract, Galvani
concluded that the purpose of this animal electricity was to
produce muscular contractions.

Galvani seems to have concerned himself principally with the
physiological processes which he believed gave rise to the
electric charges, but physicists began immediately to seek for
other sources of the electricity. The one observation which
seemed to offer a definite suggestion as to the possible source
of the electrical charge was the fact that, in general two
different metals must be used to connect the muscle and nerve
before a discharge would take place from the one to the other.
This made Galvani's theory that the metals served merely as
conductors seem improbable. On the other hand, it was sometimes
possible to get the muscular contractions by using a single
bent wire or rod to connect the nerve and muscle, especially if
the two ends were of different degrees of polish, or if one end
was warmer than the other.

Volta was apparently the first to suggest that the electricity
which seemed to be generated in Galvani's experiments might
have its source in the contact of the two metals. Several
writers called attention to an apparent relation between
Galvani's experiments and a phenomenon announced by J. G.
Sulzer, in 1760. Sulzer found that if pieces of lead and silver
were placed upon the tongue separately no marked taste was
produced by either, but that if while both were on the tongue
the metals were brought into contact a strong taste was
produced which he compared to the taste of iron vitriol. Here
was a case of undoubted stimulation of the nerves of taste by
the contact of two metals, and it seemed not improbable that
other nerves might be stimulated in the same manner. In the
meantime Mr. John Robison had increased the Sulzer effect
greatly by building up a pile of pieces of zinc with silver
shillings and placing these in contact with the tongue and the
cheek.

It was the question as to the possibility of producing the
electric charge by mere metallic contact which led Cavallo to
make his experiments upon contact electrification. Thus Cavallo
says in Volume III. of "A Complete Treatise on Electricity,"
published in 1795:

'The above mentioned singular properties, together with some
other facts, which will be mentioned in the sequel induced Mr.
Volta, to suspect that possibly in many cases the motions are
occasioned by a small quantity of electricity produced by the
mere contact of two different metals; though he acknowledges
that he by no means comprehends in what manner this can happen.
This suspicion being entertained by so eminent a philosopher as
Mr. Volta, induced Dr. Lind and myself to attempt some
experiment which might verify it; and with this in view we
connected together a variety of metallic substances in diverse
quantities, and that by means of insulated or not insulated
communications; we used Mr Volta's condenser, and likewise a
condenser of a new sort; the electrometer employed was of the
most sensible sort; and various other contrivances were used,
which it will be needless to describe in this place; but we
could never obtain the smallest appearance of electricity from
those metallic combinations. Yet we can infer to no other
conclusion, but that if the mere combination, or contact, of
the two metals produces any electricity, the quantity of it in
our experiments was too small to he manifested by our
instruments.'

Later, on page 111 of the same volume, he says:

'After many fruitless attempts, and after having sent to the
press the preceding part of this volume, I at last hit upon a
method of producing electricity by the action of metallic
substances upon one another, and apparently without the
interference of electric bodies. I say apparently so, because
the air seems to be in a great measure concerned in those
experiments, and perhaps the whole effect may be produced by
that surrounding medium. But, though the irregular,
contradictory, and unaccountable effects observed in these
experiments do not as yet furnish any satisfactory theory, and
though much is to be attributed to the circumambient air, yet
the metallic substances themselves seem to be endowed with
properties peculiar to each of them, and it is principally in
consequence of those properties that the produced electricity
is sometimes positive, at other times negative, and various in
its intensity.'

Cavallo then proceeds to describe the experiments on contact
electrification which were described in the previous paper
referred to at the beginning of the article.

Cavallo's experiments were evidently made in 1795. In the
following year Volta announced the discovery of the electrical
current. In a letter written to Gren's Neues Journal der
Physik, August, 1796, Volta says:

'The contact of different conductors, particularly the
metallic, including pyrites and other minerals as well as
charcoal, which I call dry conductors, or of the first class
with moist conductors, or conductors of the second class,
agitates or disturbs the electric fluid, or gives it a certain
impulse. Do not ask in what manner: it is enough that it is a
principle and a great principle.'

It will be seen that at this stage of his discovery Volta was
inclined to attribute tho origin of the current to the contact
between the metals and his moist "conductors of the second
class," though later in the same article he says it is
impossible to tell whether the impulse which sets the current
in motion is to be attributed to the contact between the metals
themselves or between the two metals and the moist conductor,
since either supposition would lead to the same results.

Later, as was shown in the previous paper by the present writer
Volta came to regard the metallic contact as the cause of the
electromotive force. In a letter written to Gren in 1797 and
published as a postscript to his letter of August, 1796, Volta
says:

'Some new facts, lately discovered, seem to show that the
immediate cause which excites the electric fluid, and puts it
in motion, whether it be an attraction or a repulsive power, is
to be ascribed much rather to the mutual contact of two
different metals, than to their contact with moist conductors.'

The new facts, "lately discovered," to which Volta attributes
his change of view were his repetitions of Bennett's
experiments of 1789.

Volta apparently thought that the current was not only set up
by the contact of the two metals of a pair, but that it was
kept up by the mutual action of the metals on each other. He
accordingly made no attempt to discover whether any changes
took place in his circuit while the current was being
generated. The chemical action on his metals and the
dissociation in his electrolyte seem to have entirely escaped
his attention. At least, he did not attach enough importance to
them to mention them anywhere in his description of his
apparatus.

In the meantime a chemical explanation of the phenomena
observed by Galvani had been proposed in 1792 by Fabroni, a
physicist of Florence. After discussing the Sulzer phenomenon
already mentioned in this paper, Fabroni argues that the
peculiar taste caused by bringing the two metals into contact
while on the tongue is due to a chemical, rather than to an
electrical, action. He then discusses the different chemical
behavior of metals when taken singly and when placed in contact
with other metals. He says:[2]

[2] The following quotations from Fabroni have been translated
by the present writer from the German of Ostwald's
"Elektrochemie," pp. 103, ff.



I have already frequently observed that fluid mercury retains
its beautiful metallic luster for a long time when by itself;
but as soon as it is amalgamated with any other metal it
becomes rapidly dim or oxidized, and in consequence of its
continuous oxidation increases in weight.

I have preserved pure tin for many years without its changing
its silvery luster, while different alloys of this metal which
I have prepared for technical purposes have behaved quite
otherwise.

I have seen in the museum at Cortonne Etrusean inscriptions
upon plates of pure lead which are perfectly preserved to this
day' although they date from very ancient times; on the other
hand, I have found with astonishment in the gallery of Florence
that the so-called "piombi" or leaden medallions of different
popes, in which tin and possibly some arsenic have been mixed
to make them harder and more beautiful, have fallen completely
to white powder, or have changed to their oxides, though they
were wrapped in paper and preserved in drawers.

In the same way I have observed that the alloy which was used
for soldering the copper plates upon the movable roof of the
observatory at Florence has changed rapidly and in places of
contact with the copper plates has gone over into a white
oxide.

I have heard also in England that the iron nails which were
formerly used for fastening the copper plates of the sheathing
of ships were attacked on account of contact, and that the
holes became enlarged until they would slip over the heads of
the nails which held them in position.

It seems to me that this is sufficient to show that the metals
in these cases exert a mutual influence upon each other, and
that to this must be ascribed the cause of the phenomena which
they show by their combination or contact.

After discussing some of the experiments on nerve stimulation
which had been made by Galvani and others, Fabroni argues that
these are principally, if not wholly, due to chemical action,
and that the undoubted electrical phenomena which sometimes
accompany them are not the cause of the muscular contractions.

In discussing the nature of the chemical changes produced in
two metals by their mutual contact, Fabroni says:

'Since the metals have relationships with each other, the
molecules must mutually attract each other as soon as they come
into contact. One can not determine the force of this
attraction, but I believe it is sufficient to weaken their
cohesion so that they become inclined to go into new
combinations and to more easily yield to the influence of the
weakest solvents.'

In order to further show the weakening of cohesion by the
contact of two metals, Fabroni describes the results of some
experiments which he has made. He says:

'In order to assure myself of the truth of my assumptions, I
put into different vessels filled with water:

(1) Separate pieces, for example, of gold in one, silver in
another, copper in the third, likewise tin, lead, etc.

(2) In other similar vessels I put pieces of the same metals in
pairs, a more oxidizable and a less oxidizable metal in each
pair' but separated from each other by strips of glass

(3) Finally, I put in other vessels pairs of different metals
which were placed in immediate contact with each other.

The first two series suffered no marked change, while in the
latter series the more oxidizable metal became visibly covered
with oxide in a few instants after the contact was made.'

Fabroni found that under the above circumstances his oxidizable
metals dissolved in the water, and in some cases salts were
formed which crystallized out. He then compares the metals in
contact with each other in water with the metals on the tongue
when brought into contact, as in Sulzer's experiment, and the
two metals touching each other by which different points on a
nerve were touched to produce the muscular twitchings in
Galvani's experiments, and concludes that the chemical action
upon the metals was the same in each case, and that the other
phenomena observed must have resulted from this chemical
action. It is not strange that when Volta showed later that an
electric current passed between the metals in all of tho above
cases Fabroni should regard the chemical action which he had
previously observed as the cause of this current.

Ten years after the publication of Fabroni's original paper,
Volta wrote a letter to J. C. Delamethrie which was published
in Vol. I of Nicholson's Journal. This letter was written after
the chemical changes in the voltaic cell had received a great
deal of attention by many experimenters, the most prominent of
whom was Davy. To show that Volta's theory as to the source of
the current was not affected by these investigations, a
quotation from this letter is given below.

'You have requested me to give you an account of the
experiments by which I demonstrate, in a convincing manner,
what I have always maintained, namely, that the pretended
agent, or GALVANIC FLUID, is nothing but common electrical
FLUID, and that this fluid is incited and moved by the simple
MUTUAL CONTACT OF DIFFERENT CONDUCTORS, particularly the
metallic; strewing that two metals of different kinds,
connected together, produce already a small quantity of true
electricity, the force and kind of which I have determined;
that the effects of my new apparatus (which might be termed
electromotors), whether consisting of a pile, or in a row of
glasses, which have so much excited the attention of
philosophers, chemists, and physicians; that these so powerful
and marvelous effects are absolutely no more than the sum total
of the effects of a series of several similar metallic couples
or pairs; and that the chemical phenomena themselves, which are
obtained by them, of the decomposition of water and other
liquids, the oxidation of metals, &c., are secondary effects;
effects, I mean, of this electricity, of this continual current
of electrical fluid, which by the above mentioned action of the
connected metals, establishes itself as soon as we form a
communication between the two extremities of the apparatus, by
means of a conducting bow; and when once established, maintains
itself, and continues as long as the circuit remains
interrupted.'[3]

[3] This seems to be a misprint for uninterrupted.



Further along in the same letter Volta reiterates his
conviction that the contact of the two metals furnishes the
true motive power of the current. Thus he says (p. 138):

'As to the rest, the action which excites and gives motion to
the electric fluid does not exert itself, as has been
erroneously thought, at the contact of the wet substance with
the metal, where it exerts so very small an action, that it may
be disregarded in comparison with that which takes place, as
all my experiments prove, at the place of contact of different
metals with each other. Consequently the true element of my
electromotive apparatus, of the pile, of cups, and others that
may be constructed according to the same principles, is the
simple metallic couple, or pair, composed of two different
metals, and not a moist substance applied to a metallic one, or
inclosed between two different metals, as most philosophers
have pretended. The humid strata employed in these complicated
apparatus are applied therefore for no other purpose than to
effect a mutual communication between all the metallic pairs,
each to each, ranged in such a manner as to impel the electric
fluid in one direction, or in order to make them communicate,
so that there may be no action in a direction contrary to the
others.'

At the end of the above letter as published in Nicholson's
Journal, the editor, William Nicholson, comments at length on
Volta's theory of the source of current in the cell and calls
attention to the fact that Davy had already made cells by the
use of a single metal and two different liquids. At the
conclusion of his comments he calls attention to the fact that
Bennett and Cavallo had performed experiments with contact
electrification prior to Volta's experiments, and says in
conclusion, after referring to Bennett,

'This last philosopher, as well as Cavallo, appears to think
that different bodies have different attractions or capacities
for electricity; but the singular hypothesis of electromotion,
or a perpetual current of electricity being produced, by the
contact of two metals is, I apprehend, peculiar to Volta.'

This peculiar theory of Volta's probably never gained many
adherents and was necessarily abandoned as soon as the energy
relations of the current were considered, but the controversy
as to whether the electrical current or the accompanying
chemical changes was the primary phenomenon soon became
transferred to a quite different field, viz., to the origin of
the electrical charges which Bennett had shown resulted from
the contact of different metals. Bennett attempted to account
for the phenomena which he had observed on the hypothesis that
different substances "have a greater or less affinity with the
electric fluid," and Cavallo says:

'I am inclined to suspect that different bodies have different
capacities for holding the electric fluid.'

Volta reaches a similar conclusion after repeating some of
Bennett's experiments. In referring to this decision of Volta
as to the origin of the electric charge in contact
electrification, Ostwald says:

'We stand here at a point where the most prolific error of
Electrochemistry begins, the combating of which has from that
time on occupied almost the greater part of the scientific work
in this field.'

The error, from Ostwald's point of view, lies in the assumption
that the transference of electricity from the one metal to the
other is a primary phenomenon of metallic contact. He, with
many others, including some of the most distinguished
physicists and chemists of the past century, regard the
electrical transference as a secondary phenomenon resulting
from the previous oxidation of one of the metals. Thus Lodge,
in discussing the opposite electrification of plates of zinc
and copper when brought into contact says:

'The effective cause of the whole phenomenon in either case is
the greater affinity of oxygen for zinc rather than copper.'

The apparent conflict of opinion between those who hold that
the different affinities of the metals for oxygen is the cause
of the rearrangement of their electrical charges when brought
into contact and those who hold with Bennett and Cavallo that
the metals in their natural state have different affinities for
the electrical fluid must disappear when we recognize that all
affinity, and consequently the affinity for oxygen, must be an
electrical attraction. If zinc has an affinity for oxygen, it
must be because the zinc is either electropositive or
electronegative to oxygen. If it has a greater affinity for
oxygen than copper has, then the zinc must be either
electropositive or electronegative to copper. This being the
case, and both being conductors, it is not surprising that some
electricity will flow from one to the other when the two metals
are brought into contact.

Those writers who attribute the oxidation theory of contact
electrification to Fabroni apparently overlook the fact that
not oxidation, but the weakening of the cohesion of at least
one of the metals due to their contact, was the primary
phenomenon in Fabroni's theory. When this is remembered, it is
seen that the observations of Bennett and Fabroni, instead of
furnishing arguments for two conflicting theories, actually
serve, as all true scientific observations must, to supplement
each other.

Thus we now know that cohesion or affinity is an electrical
attraction between the atoms or molecules of a body. The only
known methods of changing the electrical attraction between two
bodies whose distances and directions from other bodies remain
constant is by varying the magnitude of their charges or by
changing the specific inductive capacity of the medium between
them. Bennett observed that when two pieces of different metal
in their normal electrical condition are placed in contact,
there is a redistribution of the charges of their surface
atoms. Fabroni observed under the same conditions a change in
the surface cohesion of the two metals.

To the present writer this seems the actual sequence of
phenomena, viz., a redistribution of the charges of the surface
atoms of the metals, a consequent change in surface cohesion
and a resultant oxidation of one of the metals.



ON CERTAIN RESEMBLANCES BETWEEN THE EARTH AND A BUTTERNUT

BY PROFESSOR A, C. LANE

TUFTS COLLEGE

THE drama of the earth's history consists in the struggle
between the forces of uplift and the forces of degradation. The
forces of uplift are mainly the outward expression of the inner
energy and heat of the earth, whether they be the volcano
belching its ashes thousands of meters into the air, or the
earthquake, with the attendant crack or fault in the earth's
crust, leading to a sudden displacement, and sending, far and
wide, a death-dealing shock, or those mountain-building
actions, which, though they may be as gentle and gradual as
might be produced by the breathing of mother earth and the
uplifting of her bosom thereby, nevertheless, end in the huge
folds of our mountain ranges.

Against these, there are always working the forces of
degradation--the slow rotting of weathering caused by the
direct chemical action of the moist atmosphere or the
alternation of hot and cold which crumbles rocks far above the
line where rain never falls. Once the rock is rotten and
decayed, it yields readily to the forces of degradation, which
drag it down--the beating of the rain, the rush of the
avalanche or of the landslide, the tumult of the torrent, the
quieter action of the muddy river in its lower reaches or the
mighty glacier which transfers fine and coarse material alike
toward the sea.

These actions are always going on. Are they always equally
balanced, or are there periods when the forces of elevation are
more active, the forces of degradation not so powerful, as
against other times in which the forces of degradation alone
are at work? If there is inequality in the balance and struggle
of these contending forces, the great periods or acts in the
geologic drama might thus be marked off as Chamberlin suggests.
Newbery, Schuchert and others have pointed out that there seem
to have been great cycles of sedimentation which may be
interpreted as due to the alternate success, first of the
factors of elevation, then of those of degradation.

Suppose, for instance, that there has been an epoch of
elevation, that mountain chains have been lifted far into the
sky and volcanoes have sent their floods of lava forth, and
fault-scarped cliffs run across the landscape and that then,
for a while, the forces of elevation cease their work. Little
by little, the mountains will be worn down to a surface of less
and less relief, approaching a plain as a hyperbola approaches
its asymptote--a surface which W. M. Davis has called
peneplain.

But where will the material thus worn go? Into the sea. Going
into the ocean it will raise the level of the sea slowly but
surely. At present, for every four feet of elevation taken off
the land, there will be something like one foot rise of the
ocean level, and this rise may take only thirty thousand
years--a long time in human history, but not so long in the
history of the earth. All the time, then, that the forces of
the atmosphere are wearing down the surface of the earth to the
sea level the sea is rising and its waves are producing a plain
of marine denudation which rises slowly to meet the peneplain
which is produced by degradation. In the beginning of this
cycle, where the forces of degradation have their own way,
coarse material may be brought down by torrents from the
mountains, and the glaciers, which find their breeding place in
these high elevations, may drag down and deposit huge masses of
boulder clay. But, little by little as the mountains are
lowered, the sediments derived from them will become finer and
finer and glaciers will find fewer and fewer sources.

Not only that, but the growth of seas extending over the
continents will tend to change the climate, we shall have a
moister, more insular climate, we shall have a greater surface
of evaporation, and thus, on the whole, a more equable
temperature throughout the world. We know that, at present, the
extremes of cold and hot are found far within the interior of
the continents. Continental climates are the climates of
extremes, and on the whole extremes are hurtful to life. So
then as the forces of degradation tend to lower the continents
beneath the sea level glaciers and deserts and desert deposits
alike must also disappear. Vegetation will clothe the earth,
and marine life swarm in the shallow seas of the broadening
continental shelf. Under the mantle of vegetation, mechanical
erosion will be less, that is, the breaking up of rocks into
small pieces without any very great change, but the rich soil
will be charged with carbon dioxide, and chemical activity will
still go on. Rivers will still contain carbonates, even though
they carry very little mud, and in the oceans the corals and
similar living forms will deposit the burden of lime brought
into the sea by the rivers. Thus, if forces of degradation have
their own way, in time there will be a gradual change in
dominant character, from coarse sediments to fine, from rocks
which are simply crumbled debris to rocks that are the product
of chemical decay and sorting, so that we have the lime
deposited as limestone in one place and the alumina and silica,
in another. We shall have a change from local deposits, marine
on the edges of large continents, or land deposits, very often
coarse, with fossils few and far between, to rocks in which
marine deposits will spread far over the present land in which
will appear more traces of that life that crowded in the
shallow warm seas which form on the flooded continents. We
shall have a transition from deposits which may be largely
formed on the surface of the continents. lakes, rivers, salt
beds and gypsum beds, due to the drying up of such lakes and
the wind-blown deposits of the steppes, to deposits which are
almost wholly marine.

Now, I need not say (to those who are familiar with geology)
that we have indications of just such alternations in times
passed. There are limestones abounding in fossils, with a
cosmopolitan life very wide spread to be recognized in every
continent, such as used to be known as the Trenton limestone,
the mountain limestone, the chalk. Perhaps every proper system
and period should be marked by such a limestone in the middle.
The time classed as late Permian and Triassic on the other hand
was one of uplift, disturbance, volcanic action and extreme
climates, which gave us the traps of Mt. Tom, the Palisades of
the Hudson, the bold scenery of the Bay of Fundy and the gypsum
and red beds which are generally supposed to be quite largely
formed beneath the air and beds of tillite formed beneath
glaciers. Then in the times succeeding, in many parts of the
world, degrading forces were more effective than uplifting so
that the mountains became lower, and the seas extended farther
over the continents. Then the prevalence of lime sediments was
so great that the "chalk" was thought to be characteristic
everywhere. And about the time the "chalk" the land was reduced
to a peneplain. A similar cycle may be traced from the
Keweenawan rocks to the group of limestones so widespread over
the North American continent and so full of fossils, which to
older geologists and oil drillers have been known, in a broad
way, as Trenton.

All this introduces a question--to which I wish to suggest an
answer--How is it that these cycles came to be? Were the outer
rock crust of the earth perfectly smooth the oceans would cover
it to the depths of thousands of feet and it is only by the
wrinkling of such a crust that any part of it appears above the
ocean. If the earth had a cool thin crust upon a hot fluid
interior, and that thin crust were able to sustain itself
during geologic ages so that the shrinkage should accumulate
within, until finally collapse came, giving an era of uplift,
it is obvious that we could account for such cycles. There is
very clear evidence that the outermost layer of the earth's
crust is but a thin shell like the outer shuck or exocarp of a
butternut, so thin that it is not at all possible that it can
sustain itself for more than a hundred miles or so, or for more
than a very few years at the outside. Hayford's[1]
investigations are the latest that show that the continents
project because, on the whole, they are lighter, they float,
that is, above the level of the oceans because there is a mass
of lighter rock below, like an iceberg in the sea. Here the
likeness between nut and earth fails and it would be more like
the earth if the outer shuck were thicker in certain large
areas. If this extra lightness or "isostatic compensation" is
equally distributed, Hayford finds[2] that the most probable
value of the limiting depth is 70 (113 km.) miles, and
practically certain that it is somewhere between 50 (80 km.)
and 100 (150 km.) miles; if, on the other hand, this
compensation is uniformly distributed through a stratum 10 (16
km.) miles thick at the bottom of the crust so that there is a
bulging of the crust down into a heavier layer below to balance
the projection of the mountains above, as I think much more
likely, then the most probable depth for the bottom of the
outer layer is 37 (60 km.) miles. This layer is much thinner
than the outer layer of the figure and is supposed to yield to
weight placed as, though more slowly than, new thin ice bends
beneath the skater.

[1] The figure of the earth and isostasy from measurements in
the U.S. Dept. of Commerce and Labor, 1909, p. 175.

[2] loc. cit., p. 175.



There are a number of facts which support this so-called theory
of isostasy, according to which the crust of the earth is not
capable of sustaining any very great weight, though it may be
at the outside rigid, but is itself essentially like a flexible
membrane resting on a layer of viscous fluid. However viscous
this fluid may be and rigid to transitory quickly shifting
strains like those produced by the earth's rotation, it does
NOT REMAIN AT REST in a state of strain (at any rate if this
strain passes limits which are relatively quite low). Not only
are, according to Hayford's observations, the inequalities of
the North American continent compensated for by lighter
material below, so that the plumb- bob deflections are only one
twentieth what they would be if they rested upon a rigid
substratum of uniform density, but other facts that lead to the
same conclusion are the apparent tendency of areas of
sedimentation to slowly settle under their load, the apparent
settling of the Great Lake region under a load of ice and
springing up again since the removal of the ice. But if the
theory of isostasy is true, one would at first say that there
could be no great accumulation through a geologic period of
stresses which would finally yield in the shape of folded
mountain ranges. It has, in fact, been suggested that mountain
ranges have been slowly folded and lifted as the stress which
produced them accumulated and this would seem to be true if one
considers only the outer crust, but on the other hand, as we
have pointed out, there are indications in the history of the
earth of periods of relative quiescence followed by periods of
relatively considerable disturbance.

How can these two theories be reconciled in accordance with
what we know of the laws of physics and chemistry and those of
the earth's interior? It seems to me they can by making
suppositions which are perfectly natural regarding the state of
the earth's interior.

We are at liberty to suppose if the facts point that way that
there are the following layers in the earth's masses:--First,
the external, rigid and brittle layer; second, a layer under
such temperature and pressure that it is above its plastic
yield point and may be considered as a viscous fluid. The
pressure must continue to increase toward the center. We do not
know what is the temperature, but it is perfectly possible that
at a greater depth the earth may become rigid once more if the
effect of pressure in promoting solidity and rigidity
continues, as Bridgman tells me he thinks probable. We do not
even have to assume a change in the chemical composition of the
earth's substance, though it is perfectly allowable. This,
then, will be a third layer, once more rigid, perhaps extending
to the center and of very considerable thickness and capable of
accumulating strain from long periods. Blanketed as it would be
by thousands of meters of the first two layers, any change must
be relatively slow.

Kelvin in his computation of the age of the earth from cooling
assumed for the interior of the earth constant conditions. It
is now generally accepted that this is not probable, and that
whether it cooled from a gas or coagulated from planetesimals,
it became solid first at the center which then would be
hottest, and both Becker[3] and A. Holmes[4] assume an initial
temperature gradient. If that gradient were greater than the
gradient of steady flow the conditions of steady flow would be
approached most rapidly at the exterior, the loss of heat and
energy would be altogether from within and it is easy to
arrange for conditions mathematically in which almost all the
loss of energy would come from the very interior, near the
center. What will be the effect? A paradoxical one, if the part
outside the center is rigid enough to be self-sustaining. The
central core will become a gas!

[3] Bull. Geol. Soc. Am., Vol. 26, 1915, p. 197, etc.
[4] Geological Magazine, March and April, 1913.



This is so contrary to our ordinary experience and ideas, in
which loss of heat tends to change from gas to fluid and solid,
that we must look into it a little to make it sound reasonable.
The recent brilliant work of P. W. Bridgman (contrary to the
earlier speculations of Tammann) indicates that the effect of
increased pressure, at high temperature, makes a substance
solid and crystalline. Crowd any atoms close enough together,
and no matter how fast they expand or contract under the
influence of heat the crystalline atomic forces will get to
work when they are crowded within their range, and the closest
packing, hence that which will yield most to the pressure,
hence that which is likely to take place, is when they are all
regularly arranged facing the same way. Such an arrangement we
call crystalline. Just so when they want to pack the most
people into the car of an elevator they ask them to all face to
the front. Keep this metaphor a moment. Any one who should try
to penetrate such a crowd would find it a hard job. They would
offer a very effective rigidity. Now suppose them to sweat in
those confined quarters their fat away, their phlogiston, their
caloric. If the walls of the car remained rigid while the
individuals therein shrunk they might after a while be able to
turn around or even move around in a car. Such is then the
supposed condition of the atoms in the FOURTH, the central,
layer of the earth's crust. This assumes that the middle layer
is rigid and sustains itself, like the shell of a nut, as in
the figure, while within the atoms are in a less rigid
condition. That such a shell might be self-sustaining is
suggested by an experiment of Bridgman, who put a marble with a
gas bubble in it under a pressure of something like 150,000
pounds to the square inch without producing any perceptible
change.

As loss of energy from the earth's interior went on this
central core of gas would enlarge until the middle shell was
hardly self-supporting. Then, probably at some time of
astronomic strain when the earth's, orbit was extra elliptical,
it would collapse, in collapsing generate heat, and so stop the
process. The collapse would be transmitted to the viscous layer
which might be increased, motions set up in it, and so a
wrinkling of the outer thin crust on which we live.

Then there would be four layers to the earth like the butternut
of the figure. First, the inner kernel of gas; second, the hard
shell or endocarp; third, a viscous layer like the sarcocarp or
pulp, and outside of all the wrinkled crust of exocarp. If such
is the structure of the earth we may have in the very structure
of the earth itself a reason why from time to time there are
collapses of the middle layer leading to elevations of portions
of the outer rind, and marking off the chapters in geological
history, the lines between geological systems.

There are reasons in facts of observation for believing that
such is the structure of the earth, of which I have as yet said
nothing. We see the interior of a glass marble, I saw the
bubble in the interior of Bridgman's glass marble, how? By
waves, vibrations, which start from the sun or some other
source, and going through it reach my eye. Though the earth is
not penetrated by sunlight it is penetrated by the waves and
vibrations that start from that jar produced by a crack which
we call an earthquake. These vibrations can be received by that
eye of the geologist called a seismograph. The seismologist
tells us there are three kinds of waves sent out in an
earthquake. If you notice the explosion of a blast at a little
too close distance you will notice that you see it first, then
hear it, and then perhaps a little later a few chips of rock
may come flying past your ears. These three things correspond
somewhat to the three kinds of waves which spread forth from an
earthquake. But in the case of the explosion we see the blast
first, then hear later. The waves which produce the sensation
of sight are, we know, lateral disturbances, the waves which
produce the sensation of sound are waves of condensation, whose
motion is in the direction of their propagation and they come
later. In the case of the jars of earth, the reverse is true.
The first set of waves to arrive are the waves which are due to
compression--vibrations in the direction in which the waves are
produced--and correspond to sound waves. Later come waves which
are transverse sidewise disturbances of the solid mass of the
earth. As we can easily see, in an earthquake jar traveling
from the opposite end of the earth, there should be no
insurmountable difficulty in recognizing the jar, which is a
direct upthrow from one which would tilt it to the right or
left. Now there is a law of Laplace by which the velocity of
spread of sound waves through gas may be calculated. That this
law should hold at temperatures and pressures so high as those
that must exist in the middle of the earth is, of course, a
question, but it will be interesting to see how nearly the
actual velocity of about 10 kilometers a second compares with
the velocity which such waves should have in gas of a density
and under a pressure such as a gas near the center of the earth
must have. Using Oldham's figures (and they seem to be
confirmed by the recent investigations of E. Rudolph and S.
Szirtes[18]), we find that the time of transmission of these
first and fastest preliminary compression tremors is about
twice the velocity of such a jar according to Laplace's law in
as dense a mass of gas, provided the ratio of the specific heat
of a gas at constant pressure to that of a gas at constant
volume remains 1.4, which is for many substances. But as it is
1.6 for mercury the discrepancy is not more than I had
expected.

[5] Gerlands, "Beitrage zur Geophysik," XI., Band, 1 Heft,
1911, p. 132. "Das kolumbianische Erdbeben am 31 January,
1906."



The second preliminary tremors arriving later are due to the
lateral disturbance. Their propagation is much less rapid when
the point of origin is nearly opposite the point of receival.
In other words there is a core within the earth about 0.4 of
the radius in radius, in which according to Oldham, these
lateral waves have much less velocity. Now in a gas there is
less resistance to lateral displacement than in a solid, and
the less the resistance the less the velocity, so that this
fact fits in with the idea of a gaseous core perfectly. If
there is such n core, moreover, of less rigidity it would have
less refraction. Consequently waves not striking the border
above the angle of total reflection would be totally reflected,
and just as around a bubble there is a dark border where the
light does not get through so at a certain distance from the
source of an earthquake there would be a circle (it is really
about 140 degrees of arc away), where no second tremors would
be felt. Here again, though seismograph stations are as yet
few, fact and theory are apparently going to correspond.

The last type of earthquake waves follow around the outer layer
of the crust.

There is one farther line of verification to which I had
addressed myself. Is it likely that the loss of heat and energy
from the central nucleus, at the rate which we know at the
surface from a central nucleus of anything like 0.4 the radius
of the earth, would give a shrinkage of anything like the
amount indicated by the mountain ranges, in anything like the
time which we are led to assign on other grounds to the
geologic periods?

Rudski has also attempted to connect the shrinkage and age of
the earth. Both these methods depend on how fast the earth is
losing heat, that is on the geothermal gradient. Since at
present, owing to the apparently large but unknown contribution
of radioactivity to that gradient we know very little about
what the other portion is, it seems unwise to give any figures,
especially as almost all the numerical data are largely guess
work. It will, however, be fair to say that very long times for
the age of the earth seem to be indicated, nearer millions of
millions than millions unless the radius of the gaseous core
was mainly small or its rate of contraction with loss of
temperature high.



THE CASH VALUE OF SCIENTIFIC RESEARCH

BY PROFESSOR T. BRAILSFORD ROBERTSON

UNIVERSITY OF CALIFORNIA

THERE can be no doubt that the average man and woman in Europe
and America to-day professes a more or less nebulous feeling of
respect and admiration for the scientific investigator. This
feeling is not logical, for very few have ever met or seen a
scientist, fewer still have ever seen the inside of a
scientific laboratory, and hardly any have ever seen scientific
research in the making.

The average man in the street or man of affairs has no very
clear conception of what manner of man a "scientist" may be. No
especial significance attaches in his mind to the term. No
picture of a personality or his work arises in the imagination
when the word "scientist" is pronounced. More or less
indefinitely, I suppose, it is conceded by all that a scientist
is a man of vast erudition (an impression by the way which is
often strikingly incorrect) who leads a dreary life with his
head buried in a book or his eye glued to telescope or
microscope, or perfumed with those disagreeable odors which, as
everybody knows, are inseparably associated with chemicals. The
purpose of this life is not very clear, but doubtless a vague
feeling exists in the minds of most of us that people who are
willing to pursue such an unattractive career must be worthy of
admiration, for despite all the triumphs of commercialism,
humanity still loves idealism, even idealism which seems
objectless because it is incomprehensible.

From time to time the existence of the scientific man is
recalled to the popular mind by some extravagant headlines in
the daily press, announcing some utterly impossible "discovery"
or some extravagantly nonsensical dictum made by an alleged
"scientist." The "discovery" was never made, the dictum never
uttered, but no matter; to-morrow its place will be taken by
the latest political or matrimonial scandal, and the public,
with excellent good sense, will forget all about it.

From time to time, also, there creeps gradually into the public
consciousness a sense that SOMETHING HAS HAPPENED. Brief
notices appear in the press, at first infrequently and then
more frequently, and an article or two in the popular
monthlies. The public becomes languidly interested in a new
possibility and even discusses it, sceptically. Then of a
sudden we are awakened to the realization of a new power in
being. The X-ray, wireless telegraphy or the aeroplane has
become the latest "marvel of science," only to develop in a
very brief period into a commonplace of existence.

Many indeed are aware that we owe these "marvels" to scientific
research, but very few indeed, to the shame of our schools be
it spoken, have attained to the faintest realization of the
indubitable fact that we owe almost the entirety of our
material environment, and no small proportion of our social and
spiritual environment, to the labors of scientists or of their
spiritual brethren.

Long ago, in ages so remote that no record of them survives
save our heritage of labor well achieved, some pastoral savage,
more reflective and less practical than his brethren, took to
star-gazing and noting in his memory certain strange
coincidences. Doubtless he was chidden by his tribal leaders
who were hard-headed men of affairs, skilled in the
questionable art of imposing conventional behavior upon unruly
tribesmen. But he was an inveterate dreamer, this prehistoric
Newton and the fascination of the thing had gripped his mind.
In due time he was gathered to his fathers, but not before he
had passed on to a few chosen ones the peculiar coincidences he
had observed. And thus, from age to age coincidence was added
to coincidence and the result of all this "unpractical" labor
was, at long last, a calendar. Let who will attempt to estimate
the cash value of this discovery; I will not attempt the
impossible. I will merely ask you to picture to yourselves
humanity in the condition of the Australian Aboriginal or of
the South African Bushman; devoid of any means of estimating
time or season save by the daily passage of the sun, and I ask
you, "supposing that through some vast calamity, a calamity
greater even than the present war, humanity could at a stroke
evolve a calendar, would it be worth while?" I for one think it
would.

The evolution of the calendar is not an inapt illustration of
the methods of science, and of the part which it has played in
shaping the destiny of man. Out of the unregarded labors of
thousands of forgotten men, and a few whom we now remember, has
sprung every detail of that vast complex of machinery, method
and measurement in which to-day we live and move and have our
being. In all ages scientific curiosity guided by the
scientific discipline of thought has forced man into new and
more complex paths of progress. Lacking the spirit of research,
a nation or community is merely parasitic, living upon the
vital achievements of others, as Rome based her civilization
upon the civilization of the Greeks. Only an indefinite and
sterile refinement of the existing environment is possible
under such circumstances, and humanity stays stationary or
sinks back into the semibarbarism of the middle ages.

The few scattered students of nature of that day picked up the
clue to her secrets exactly as it fell from the hands of the
Greeks a thousand years before. The foundations of mathematics
were so well laid by them that our children learn their
geometry from a book written for the schools of Alexandria two
thousand years ago. Modern astronomy is the natural
continuation and development of the work of Hipparchus and of
Ptolemy; modern physics of that of Democritus and of
Archimedes; it was long before biological science outgrew the
knowledge bequeathed to us by Aristotle, by Theophrastus and by
Galen.[1]

If, therefore, we ask ourselves what has been the value of
science to man, the answer is that its value is practically the
value of the whole world in which we find ourselves to-day, or,
at any rate, the difference between the value of our world and
that of a world inhabited by Neolithic savages.

The sweeping nature of this deduction may from its very
comprehensiveness fail to carry conviction to the reader. But
concrete illustrations of the value which scientific research
may add to our environment are not far to seek. They are
afforded in abundance by the dramatic achievements of the past
century of human progress, in which science has begun painfully
and haltingly to creep into its true place and achieve its true
function.

In the year 1813 many important events occurred. The power of
Napoleon was crumbling in that year and countless historians
have written countless pages describing innumerable events,
great and small, which accompanied that colossal downfall. But
one event of that year, of which we do not read in our
historical memoirs and school books was the discovery by Sir
Humphry Davy, in the humble person of a bookbinder's
apprentice, of the man who will probably stand out forever in
the history of science as the ideal scientific man--Michael
Faraday. The manner of this discovery is revealed by the
following conversation between Sir Humphry Davy and his friend
Pepys. "Pepys, what am I to do, here is a letter from a young
man named Faraday; he has been attending my lectures, and wants
me to give him employment at the Royal Institution--what can I
do?" "Do?" replied Pepys, "put him to wash bottles; if he
refuses he is good for nothing." "No, no," replied Davy; "we
must try him with something better than that." The result was,
that Davy engaged him to assist in the laboratory at weekly
wages.[2]

[2] J. Tyndall, "Faraday as a Discoverer."



Davy made many important discoveries, but none of his
discoveries was more important than his discovery of Faraday,
and of all the events which occurred in the year 1813, the
entry of Faraday into the Royal Institution was not the least
significant for humanity.

On the morning of Christmas day, 1821, Faraday called his wife
into his laboratory to witness, for the first time in the
history of man, the revolution of a magnet around an electric
current. The foundations of electromagnetics were laid and the
edifice was built by Faraday upon this foundation in the
fourteen succeeding years. In those years and from those
labors, the electro-motor, the motor generator, the electrical
utilization of water power, the electric car, electric
lighting, the telephone and telegraph, in short all that is
comprised in modern electrical machinery came actually or
potentially into being. The little rotating magnet which
Faraday showed his wife was, in fact, the first electric motor.

What was the cash value to humanity of those fourteen years of
labor in a laboratory?

According to the thirteenth census of the United States, the
value of the electrical machinery, apparatus and supplies
produced in this country alone, in 1909 was $221,000,000. In
1907, the value of the electric light and power stations in the
United States was $1,097,000,000, of the telephones
$820,000,000, and the combined income from these two sources
was $360,000,000. Nor does this represent a tithe of the
values, as yet barely realized, which these researches placed
at our disposal. Thus in its waterfalls, the United States is
estimated to possess 150,000,000 available horse-power, which
can only be realized through the employment of Faraday's
electro-motor. This corresponds, at the conservative figure of
$20 per horse-power per annum to a yearly income of
$3,000,000,000, corresponding at 4 per cent. interest to a
capital value of $75,000,000,0000.[3]

Conservation of our National Resources," Journal of the
American Chemical Society, February, 1909.



Such was the Christmas gift which Michael Faraday presented to
the world in 1821.

Faraday died a poor man in 1867, neither for lack of
opportunity nor for lack of ability to grasp his opportunities,
but because as his pupil Tyndall tells us, he found it
necessary to choose between the pursuit of wealth and the
pursuit of science, and he deliberately chose the latter. This
is not a bad thing. It is perhaps as it should be, and as it
has been in the vast majority of cases. But another fact which
can not be viewed with like equanimity is that of all the
inexhaustible wealth which Faraday poured into the lap of the
world, not one millionth, not a discernible fraction, has ever
been returned to science for the furtherance of its aims and
its achievements, for the continuance of research.

There is no regular machinery for securing the permanent
endowment of research, and it is always and everywhere a barely
tolerated intruder. In the universities it crouches under the
shadow of pedagogy, and snatches its time and its materials
from the fragments which are left over when the all-important
business of teaching the young what others have accomplished
has been done. In commercial institutions it occasionally
pursues a stunted career, subject to all the caprices of
momentary commercial advantage and the cramped outlook of the
"practical man." The investigator in the employ of a commercial
undertaking is encouraged to be original, it is true, but not
to be too original. He must never transcend the "practical,"
that is to say, the infinitesimal rearrangement of the
preexisting. The institutions existing in the world which are
devoted to research and, research alone can almost be counted
on the fingers. The Solvay Institute in Brussels, the Nobel
Institute in Stockholm, the Pasteur Institute in France, the
Institute for Experimental Therapy at Frankfort, The Kaiser
Wilhelm Institutes at Berlin, The Imperial Institute for
Medical Research at Petrograd, the Biologisches Versuchsanstalt
at Vienna, the Biological Station at Naples, the Royal
Institution in London, the Wellcome Laboratories in England and
at Khartoum, the Smithsonian, Wistar, Carnegie and Rockefeller
Institutes in the United States; the list of research
institutes of important dimensions (excluding astronomical
observatories) is, I believe, practically exhausted by the
above enumeration, and many of them are woefully undermanned
and underequipped. At least two of them, the Solvay Institute
wholly, and the Frankfort Institute for Experimental Therapy in
part, owe their existence and continuance to scientific men,
Solvay and Ehrlich, who have contrived to combine the pursuit
of wealth and of science, and have dedicated the wealth thus
procured to the science that gave it birth.

In 1900 the value of the manufacturing industries in the United
States which had been developed from patented scientific
inventions was no less than $395,663,958 per annum,[4]
corresponding to a capital value of about $10,000,000,000. It
is impossible to arrive at any accurate estimate of the
proportion of this wealth which finds its way back to science
to provide equipment and subsistence for the investigator, who
is creating the wealth of the future. But the capital endowment
of the Rockefeller and Carnegie Institutes, the two wealthiest
institutes of research in the world is, according to the 1914
issue of Minerva, only $29,000,000. The total income (exclusive
of additions to endowments) of all the higher institutions of
learning in the United States in 1913, was only $90,000,000, of
which a minute percentage was expended in research.

[4] 12th census, Vol. 10, Part 4.



If science produces so much wealth, is there no contrivance
whereby we can cause a small fraction of this wealth to return
automatically to science and to furnish munitions of war for
fresh conquests of nature? A very small investment in research
often produces colossal returns. In 1911 the income of the
Kaiser Wilhelm Institute for Physical Chemistry was only
$21,000. In 1913 the income of the Institute for Experimental
Therapy at Frankfort, where "606" was discovered, was only
$20,000; that of the Imperial Institute for Medical Research at
Petrograd was $95,000, and that of the National Physical
Laboratory in England (not exclusively devoted to research) was
$40,000. Yet these are among the most famous research
institutions in the world and have achieved results of
world-wide fame and inestimable value both from a financial
standpoint and from the standpoint of the physical, moral and
spiritual welfare of mankind.

In 1856, Perkin, an English chemist, discovered the coal-tar
(anilin) dyes. The cost of this investigation, which was
carried out in an improvised, private laboratory was
negligible. Yet, in 1905, the United States imported $5,635,164
worth of these dyes from Europe, and Germany exported
$24,065,500 worth to all parts of the world.[5] To-day we read
that great industries in this country are paralyzed because
these dyes temporarily can not be imported from Germany. All of
these vast results sprang from a modest little laboratory, a
meager equipment and the genius and patience of one man.

W. R. Whitney, director of the research laboratory of the
General Electric Company, points out that the collective
improvements in the manufacture of filaments for electric
lamps, from 1901 to 1911, have saved the consumer and producer
no less than $240,000,000 annually. He adds with apparently
unconscious naivete that the expenses of the research
laboratory in his charge aggregate more than $100,000
annually![6] A handsome investment, this, which brings in some
two hundred million for an outlay of one hundred thousand.

Co., 1911.



According to Huxley the discovery by Pasteur of the means of
preventing or curing anthrax, silkworm disease and chicken
cholera, a fraction of that great man's life work, added
annually to the wealth of France a sum equivalent to the entire
indemnity paid by France to Germany after the war of 1870.

Humanity has not finished its conquest of nature; on the
contrary, it has barely begun. The discipline of thought which
has carried humanity so far is destined to carry it further
yet. Business enterprise and politics, the all-absorbing
interests of the majority of mankind, work in an endless
circle. Scientific research communicates a thrust to this
rotation which converts the circle into a spiral; the apex of
that spiral lies far beyond our vision. We have, not decades,
not centuries, not thousands of years before us; but, as
astronomy assures us, in all probability, humanity has millions
of years of earthly destiny to realize. Barely three thousand
years of PURPOSEFUL scientific research have brought the
uttermost ends of the earth to our doors; have made
civilization and excluded much of the most brutal and
brutalizing in life. Not more than two hundred years of
research have made us masters where we were slaves; masters of
distance, of the air, of the water, of the bowels of the earth,
of many of the most dreaded aspects of disease and suffering.
Only for forty years have we practiced antisepsis; only for
sixty years have we had anesthetics; yet life to-day is
well-nigh inconceivable without them. And all of this has been
accomplished without any forethought on the part of the
acknowledged rulers and leaders of mankind or any save the most
trumpery and uncertain provision for research. What will the
millions of years which stretch in front of us bring of power
to mankind? We can barely foreshadow things too vast to grasp;
things that will make the imaginings of Jules Verne and H. G.
Wells seem puny by comparison. The future, with the uncanny
control which it will bring over things that seem to us almost
sacred--over life and death and development and thought
itself--might well seem to us a terrifying prospect were it not
for one great saving clause. Through all that may happen to
man, of this we may be sure, that he will remain human; and
because of that we can face the future unafraid and confident
that because it will be greater, it will also be better than
the present.

What can we do to accelerate the coming of this future? Not
very much, it is true, but we can surely do something. We can
not create geniuses, often we can not discern them, but having
discerned, surely we can use them to the best advantage. It is
true that all scientific research has depended and will depend
upon individuals; Simon Newcomb expresses the matter thus:

'It is impressive to think how few men we should have to remove
from the earth during the past three centuries to have stopped
the advance of our civilization. In the seventeenth century
there would only have been Galileo, Newton and a few other
contemporaries, in the eighteenth they could almost have been
counted on the fingers, and they have not crowded the
nineteenth.'[7]

[7] "Inventors at Work," Iles, Doubleday Page, 1906.



The first thing we have to do is to discover such men, to learn
to know them or suspect them when we meet them or their works.
The next is to give them moral and financial recognition, and
the means of doing their work. Our procedure in the past has
been the reverse of this. I quote from a letter of Kepler to
his friend Moestlen:

'I supplicate you, if there is a situation vacant at Tubingen,
do what you can to obtain it for me, and let me know the prices
of bread, wine and other necessaries of life, for my wife is
not accustomed to live on beans.'

The founder of comparative psychology, J. H. Fabre, that
"incomparable observer" as Darwin characterized him, is now
over ninety years of age, and until very recently was actually
suffering from poverty. All his life his work was stunted and
crippled by poverty, and countless researches which he was the
one human being qualified by genius and experience to
undertake, remain to this day unperformed because he never
could command the meager necessary equipment of apparatus.

Once again, what can we do?

No small proportion of the population of a modern community are
alumni of some institution of higher learning, and one thing
that these can do is to see to it by every means in their power
that some measure of the spirit of academic freedom is
preserved in their alma mater. That the spirit of inquiry and
research is not merely tolerated therein but fostered and
substantially supported, morally and financially.

As members of the body politic, we can assist the development
of science in two ways. Firstly, by doing each our individual
part towards ensuring that endowment for the university must
provide not only for "teaching adolescents the rudiments of
Greek and Latin" and erecting imposing buildings, but also for
the furtherance of scientific research. The public readily
appreciates a great educational mill for the manufacture of
mediocre learning, and it always appreciates a showy building,
but it is slow to realize that that which urgently and at all
times needs endowment is experimental research.

Secondly, it is vital that public sentiment should be educated
to the point of providing the legal machinery whereby some
proportion, no matter how small, of the wealth which science
pours into the lap of the community, shall return automatically
to the support and expansion of scientific research. The
collection of a tax upon the profits accruing from inventions
(which are all ultimately if indirectly results of scientific
advances) and the devotion of the proceeds from this tax to the
furtherance of research would not only be a policy of wisdom in
the most material sense, but it would also be a policy of bare
justice.



THE PHYSICAL MICHELANGELO

BY JAMES FREDERICK ROGERS, M.D.

NEW HAVEN, CONN.

You will say that I am old and mad, but I answer that there is
no better way of keeping sane and free from anxiety than by
being mad.

HAD Michelangelo been less poetic and more explicit in his
language, he might have said there is nothing so conducive to
mental and physical wholeness as saturation of body and mind
with work. The great artist was so prone to over-anxiety and
met (whether needlessly or not) with so many rebuffs and
disappointments, that only constant absorption in manual labor
prevented spirit from fretting itself free from flesh. He
toiled "furiously" in all his mighty undertakings and body and
mind remained one and in superior harmony--in abundant
health--for nearly four score and ten years.

This Titan got his start in life in the rugged country three
miles outside Florence: a place of quarries, where stone
cutters and sculptors lived and worked. His mother's health was
failing and it was to the wife of one of these artisans that
her baby was given to nurse. Half in jest, half in earnest,
Michelangelo said one day to Vasari:

'If I have anything good in me, that comes from my birth in the
pure air of your country of Arezzo, and perhaps also from the
feet that with the milk of my nurse, I sucked in the chisels
and hammers wherewith I make my figures.'


He began his serious study of art (and with it his course in
"physical training") at fourteen, when he became apprenticed to
a painter. He was not vigorous as a child, but his bodily
powers unfolded and were intensified through their active
expression of his imagination.

His life was devoted with passion to art. He had from the start
no time for frivolity. Art became his religion--and required of
him the sacrifice of all that might keep him below his highest
level of power for work. His father early warned him to have a
care for his health, "for," said he, "in your profession, if
once you were to fall ill you would be a ruined man." To one so
intent on perfection and so keenly alive to imperfection such
advice must have been nearly superfluous, for the artist could
not but observe the effect upon his work of any depression of
his bodily well-being. He was, besides, too thrifty in all
respects to think of lapsing into bodily neglect or abuse. He
was severely temperate, but not ascetic, save in those times
when devotion to work caused him to sleep with his clothes on,
that he might not lose time in seizing the chisel when he
awoke. He ate to live and to labor, and was pleased with a
present of "fifteen marzolino cheeses and fourteen pounds of
sausage--the latter very welcome, as was also the cheese." Over
a gift of choice wines he is not so enthusiastic and the
bottles found their way mostly to the tables of his friends and
patrons. When intent on some work he usually "confined his diet
to a piece of bread which he ate in the middle of his labors."
Few hours (we have no accurate statement in the matter) were
devoted to sleep. He ate comparatively little because he worked
better: he slept less than many men because he worked better in
consequence. Partly for protection against cold, partly perhaps
for economy of time, he sometimes left his high dog-skin boots
on for so long that when he removed them the scarf skin came
away like the skin of a moulting serpent.

He dressed for comfort and not to mortify the flesh. Upon the
receipt of a present of some shirts from his nephew he writes:

'I am very much surprised ye should have sent them to me, for
they are so coarse that there is not a farm laborer here who
would not be ashamed to wear them.'

He is much pleased with a finer lot selected later by his
nephew's new wife. Perhaps he did not come up to modern notions
of cleanliness (he was early advised by his father never to
bathe but to have his body rubbed instead) but he was clean
inside, which can not be said of all who make much of a
well-washed skin.

His intensity of purpose and fiery energy expressed themselves
in his features and form. "His face was round, his brow square,
ample," and deeply furrowed: "the temples projected much beyond
the ears"; his eyes were "small rather than large," of a dark
(some said horn) color and peered, piercingly, from under heavy
brows. The flattened nose was the result of a blow from a rival
apprentice. He evidently looked the part, though for such
mental powers one of his colossal statues would seem a more
fitting mold.

Michelangelo experienced some illnesses, all but two of them of
minor moment. In 1531 he "became alarmingly ill, and the Pope
ordered him to quit most of his work and to take better care of
his health." That the illness was a storm merely of the surface
is evidenced sufficiently in that his fresco of the "Last
Judgment," probably the most famous single picture in the
world, was begun years later and completed in his sixty-sixth
year. In the work of this epoch there is more than ever the
evidence of a pouring forth of energy amounting almost to what
the critics call violence--to terribleness of action. It was
not until the age of seventy that an illness which seemed to
mark any weakening of his bodily powers came upon him. At
seventy-five, symptoms of calculus (a disease common in that
day at fifty) appeared, but, though naturally pessimistic, he
writes, "In all other respects I am pretty much as I was at
thirty years." He improved under careful medical treatment, but
the illness and his age were sufficient to cause him to "think
of putting his spiritual and temporal affairs in better order
than he had hitherto done."

He wielded the brush and the chisel with consummate skill in
his seventy-fifth year. With the later loss of cunning his
energy found vent more in the planning and supervising of
architectural works, culminating in the building of St.
Peter's, but even in these later years he took up the chisel as
an outlet for superfluous energy and to induce sleep. Though
the product of his hand was not good, his health was the better
for this mutual exercise of mind and body. In his eighty-sixth
year he is said to have sat drawing for three consecutive hours
until pains and cramps in his limbs warned him that he had not
the endurance of youth. For exercise, when manual labor proved
a disappointment, he often took horseback rides. There was no
invalidism about this great spirit, and it was not until the
day before his death that he would consent to go to bed.

In a poem of his last years he burlesques his infirmities in
his usual vigorous manner.

'I live alone and wretched, confined like the pith within the
bark of the tree.... My voice is like a wasp imprisoned within
a sack of skin and bone. ... My teeth rattle like the keys of
an old musical instrument.... My face is a scarecrow.... There
is a ceaseless buzzing in my ears--in one a spider spins his
web, in the other a cricket chirps all night.... My catarrh,
which causes a rattle in my throat, will not allow me to
sleep.--Fatigue has quite broken me, and the hostlery which
awaits me is Death.'

Few men at his age have had less reason to find in themselves
other than the changes to be expected with the passing of years
and in prose he acknowledged that he had no more affections of
the flesh than were to be expected at his age. Codiva pictures
him in his last years as "of good complexion; more muscular and
bony than fat or fleshy in his person: healthy above all
things, as well by reason of his natural constitution as of the
exercise he takes, and habitual continence in food and sexual
indulgence." His temperance and manual industry and his
"extraordinary blamelessness in life and in every action" had
been his source of preservation. He was miserly, suspicious,
quarrelsome and pessimistic, but the effects of these faults
were balanced by his better habits of thought and action. That
he, like most great men, felt keenly the value of health, is
evidenced not only by his own practice, but by his oft repeated
warnings to his nephew when choosing a wife to see that
whatever other qualities she might have she be healthy. The
blemish of nearsight he considered a no small defect and
sufficient to render a young woman unworthy of entry into the
proud family of the Buonarroti. To his own father he wrote:
"Look to your life and health, for a man does not come back
again to patch up things ill done."

One of those who look beneath unusual human phenomena for signs
of the pathologic finds Michelangelo "affected by a degree of
neuropathy bordering closely upon hysterical disease." What a
pity that more of us do not suffer from such degrees of
neuropathy--and how much better for most of us if we had such
enthusiasm for perfection, and such mania for work, at least of
that health-bringing sort in which there is absorbing colabor
of brain and hand. True it is that "there is no better way of
keeping sane and free from anxiety than by being mad."



THE CONSERVATION OF TALENT THROUGH UTILIZATION

BY PROFESSOR JOHN M. GILLETTE

STATE UNIVERSITY OF NORTH DAKOTA

TO raise the question of how to conserve talent is not an idle
inquiry. We are in no immediate danger of famine. Yet there is
an enormous interest being devoted to what is known as the
conservation of soil. Our forests contain an abundance of
timber for near purposes, and when they are gone we shall
probably find a better substitute in the direction of concrete.
Still agitation and discussion proceed relative to the
conservation of our timber supply. We hear of conservation of
childhood, of conservation of health, of conservation of
natural scenery. It is a period of agitation for conservation
of resources all along the line. This is all good. Real
intelligent foresight is manifesting itself. Civilized man
demonstrates his superiority over uncivilized man most in the
exercise of anticipation and prescience.

As compared with other natural resources, genius and talent are
relatively scarce articles. This is at least the popular
impression as to their quantity. Even scientific men, for the
most part, incline to this opinion. Unless we are able to
demonstrate that they are quite abundant this opinion must be
accepted. I shall seek to show that the estimate of the amount
of talent in existence which is usually accepted is too small.
However, we are in no peril of so inflating the potential
supply of talent and genius in the course of our remarks that
they may be regarded as universal. Nor are we likely to
discover such a rich lode of this commodity that the world may
run riot in its consumption of the visible supply. Talent
promises to remain so scarce that, granting for the moment that
it is a useful agent, its supply must be conserved.

I shall use the term talent so as to include genius. Both
talent and genius are of the same kind. Their essential
difference consists in degree. Increase what is commonly called
talent in the direction of its manifestation and it would
develop into genius. Genius is commonly thought of as something
abnormal, in the sense that it is essentially eccentric. A
genius is generally spoken of as an eccentric, erratic,
unbalanced, person. The eccentricity is then taken as
constituting the substance of the quality of genius. This is
undoubtedly a mistake. Because some geniuses have been erratic,
the popular imagination has formed its picture of all genius as
unbalanced. The majority of the world's men of genius have been
as balanced and normal in their judgments as the average man.
We may think of a genius as like the ordinary man in his
constitution. He has the same mental faculties, the same
emotions, the same kind of determinizing ability. What makes
him a genius is his power of concentration in his given field
of work. The moral quality, or zeal to accomplish, or energy
directed toward intellectual operations stands enormously above
that of the average individual. If we could confer this quality
of moral will on the common normal man possibly we would raise
him to that degree which we term genius.

In order to determine the worth of conserving talent we must
estimate its value as a commodity, as a world asset. I shall,
therefore, turn my attention first to discovering a method of
reckoning the value of eminent men.

One method open to us is what may be called the individualistic
test. Under this method we think of the individual as
individual or of his work as a concrete case of production. One
phase of this is the individual's estimate of his own powers.
We may inquire what is the man's appreciation of his own worth.
This is precarious because of two difficulties. There is an
egotistical element in individuals. It is inherent as a
historical agent of self-preservation. Most of us are like
primitive groups. The ethnologist expects to find every tribe
or horde of savages claiming to be THE PEOPLE. They ascribe
superior qualities to their group. In their names for their
group they call themselves the people, the men, and so on,
indicating their point of view.

Again, an individual, however honestly he might try, could not
estimate his own worth accurately. Let any of us attempt to see
ourselves as others see us and we shall discover the difficulty
of the undertaking. We are not able to get the perspective
because our personal feelings, our necessary selfish
self-appreciation, puts our judgments awry. Others close to us
may do little better. They are likely to either underrate us or
to exaggerate our qualities and powers. In the United States we
are called on to evaluate Mr. Taft and Mr. Roosevelt. Is either
of them a great man? Has either of them been a great president?
Opinions differ. We are too close to them. We do not know. We
give them credit, perhaps, for doing things which the age would
have worked out in spite of them. Or we think things would have
come inevitably which their personal efforts, it will be found,
were responsible for establishing. We have not yet been able to
determine accurately just how great Abraham Lincoln was. It is
almost half a century since he did his work. But we live in the
presence of the personal relative to him yet. Sentiment enters
in and obfuscates judgment.

If we turn to the product itself as mere product we are at a
loss. Unless we ask what is the import of the work we confess
we do not know. A man in Connecticut has made a manikin. It
walks, talks, does many of the things which human beings do.
But it is not alive, it is not serviceable, it can accomplish
nothing. Suppose the maker passes his life in making probably
the most intricate and perfect mechanism which has been made.
Is he a genius? We may admit that the products manifest great
ingenuity on the part of their creator, yet we feel repelled
when we think of calling the maker a genius.

The community method of rating talent is far more satisfactory.
The inventor is related to his time or to human society by
means of the usefulness of his invention. The statesman is
rated by means of the deep-seated influence for improvement he
has had on his age. The educator finds his evaluation in the
constructive spirit and method he displays in bringing useful
spirit and methods to light. The scientist is measured by the
uplift his discovery gives to the sum and substance of human
welfare. If a product which some individual creates can not be
utilized by society, its creator is not regarded as having made
a contribution to human progress. As a consequence he does not
get a rating as genius. To get the appraisal of mankind the
product of the man of talent must get generally accepted, must
fill the want of society generally or of some clientele. If a
man produces something merely ingenious, something which does
not serve a considerable portion of humanity in the way of
satisfying a want, if his creation does not pass into use, he
does not step into the current of the world's history as a
fruitful factor, he fails to attain to the rank of talent.

This objective measure of the value of the producer puts talent
into direct relation to the concept of social evolution and
progress. Society has been an evolution. Collective humanity
has gone through distinctive metamorphoses. Distinct strides in
advance have been made, tendencies have manifested themselves,
conditions have changed so that larger satisfactions have
ensued, democracy in the essential wants of mankind has been
wrought out. Society is more complex in its quantitative
aspect. It is more serviceable by reason of its greater
specialization. Since progress stands for improvement it has
come to be regarded as a desirable thing.

In the sociological conception of things the genius possesses a
specific social function. He is not a passing curiosity. He is
not produced for amusement. He does not stand unrelated. He is
the product of his age, is articulated with its life, performs
an office which is of consequence to it. He is the connecting
link between the past and the future. He takes what was and so
combines it anew as to produce what is to be. He is the
innovator, the initiator, the agent of transformation, the
creator of a new order. Hence he is the exceptional man. The
masses of men are imitators. They make nothing new, add nothing
to the mechanism of social structure, introduce no new
functions, produce no achievements, do nothing which changes
the order of things. The common people are quite as important
for the purposes of society as are the talented. Society must
be conserved most of the time or we should all float down the
stream of change too rapidly for comfort. Hence the function of
the great mass of individuals is to seize and use the
achievements which the creators, the talented have brought into
existence. We may conclude, therefore, that if society is to be
improved and if the lives of the great body of human beings are
to be endowed with more and more blessings, material and
spiritual, we must look to the men of talent, the men of
achievement, and to them 'alone, for the initiation of these
results.

We may say, then, that we have discovered not only the method
of estimating the value of talent, but also in what its value
consists. If progress is desirable, talent by means of which
that progress is secured is likewise valuable. And, like other
things, its value is measured by its scarcity. It is now
incumbent on us to attempt to discover the extent of the supply
of this commodity, both actual and possible.

I shall refer to two estimates of the amount of talent in
existence which have been made because they differ so much in
their conclusions as to the extent of talent, and because they
exhibit quite different view-points and methods.

The great English scientist and benefactor of the race, Sir
Francis Galton, in his work entitled "Hereditary Genius" made a
computation of the number of men of eminence in the British
Isles. This estimate was made nearly a half-century ago and has
generally been accepted as representing actual conditions. One
means of discovering the number was by taking a catalogue of
"Men of The Times" which contained about 2,500 names, one half
of which were Americans and Europeans. He found that most of
the men were past fifty years of age. Relative to this he
states:

'It appears that in the cases of high (but by no means in that
of the highest) merit, a man must outlive the age of fifty to
be sure of being widely appreciated. It takes time for an able
man, born in the humbler ranks of life, to emerge from them and
to take his natural position.'[1]

[1] Cattell's investigations of American men of science
disproves this statement for Americans. He finds that only a
few men enter the ranks of that class of men after the age of
fifty, and that none of that age reach the highest place. The
fecund age is from 35 to 45; ("American Men of Science," p.
575.)



After eliminating the non-British individuals he compared the
number of celebrities above fifty with males of the same age
for the whole British population. He found about 850 who were
above fifty. Of this age there were about 2,000,000 males in
the British Isles. Hence the meritorious were as 425 to
1,000,000, and the more select were as 250 to 1,000,000. He
stated what he considered the qualifications of the more select
as follows:

'The qualifications for belonging to what I call the more
select part are, in my mind, that a man should have
distinguished himself pretty frequently either by purely
original work, or as a leader of opinion. I wholly exclude
notoriety obtained by a single act. This is a fairly well
defined line, because there is not room for many men to become
eminent.'

Mr. Galton made another estimate by studying an obituary list
published in The Times in 1868. This contained 50 men of the
select class. He considered it broader than his former estimate
because it excluded men dying before they attained their
broadest reputation, and more rigorous because it excluded old
men who had previously attained a reputation which they were
not able to sustain. He consequently lowered the age to 45. In
Great Britain there were 210,000 males who died yearly of that
age. This gave a result of 50 men of exceptional merit to
210,000 of the population, or 238 to the million.

His third estimate was made by the study of obituaries of many
years back. This led to similar conclusions, namely, that about
250 to the million is an ample estimate of the number of
eminent men. He says:

'When I speak of an eminent man, I mean one who has achieved a
position that is attained by only 250 persons in each million
of men, or by one person in each 4,000.'

The other estimate of the amount of talent in existence has
been made by one of our most eminent American sociologists, the
late Lester F. Ward. The elaborate treatment of this matter is
found in his "Applied Sociology," and offers an illustration of
a most rigorous and thorough application of the scientific
method to the subject in question. The essential facts for the
study were furnished by Odin in his work on the genesis of the
literary men of France, although Candole, Jacoby and others are
laid under contribution for data. Maps, tables and diagrams are
used whenever they can be made to secure results. Odin's study
covered the period of over five hundred years of France and
French regions, or from 1300 to 1825. Out of over thirteen
thousand literary names he chose some 6,200 as representing men
of genius, talent or merit, the former constituting much the
smaller and the latter much the larger of the total number.

The object of Ward's investigation is to discover the factor or
factors in the situation which are responsible for the
production of genius. In the course of examination it was seen
that certain communities were very much more prolific than
others in producing talent. Paris, for instance, produced 123
per 100,000; Geneva, Switzerland, 196; certain chateaux as many
as 200, and some communities none at all or very few. After
considering the various factors which account for the high rate
in certain localities and the low rate or absence of merit in
others the conclusion is reached that we should expect the
presence of the meritorious class generally in even greater
numbers than it has existed in the most fruitful regions of the
French people.

Mr. Ward's studies have led him to conclude that talent is
latent in society, that it exists in greater abundance than we
have ever dared to expect, that all classes possess it equally
and would manifest it equally if obstacles were removed or
opportunities offered for its development. Education is the key
to the situation in his estimation. It affords the opportunity
which latent talent requires for its promotion, and if this
were intelligently applied to all classes and to both sexes
alike instead of securing one man of talent for each 4,000
persons as Mr. Galton held, we would be able to mature one for
every 500 of our population. This would represent an
eight-hundred-per-cent. increase of the talented class, an
eight-fold multiplication. It is an estimate of not the number
of the talented who are known to be such, but of society's
potential or latent talent.[2]

[2] Investigations made on school children by the Binet test
indicate Ward's estimate is conservative. It has been found
that from two to three out of every hundred children are of
exceptional ability, thus belonging to the talented, or at
least merit class.



Because these estimates are so divergent, it may be worth while
to consider the reason for the difference. And in taking this
up we come to the fundamentally distinct point of view of the
two investigators. Mr. Galton's work is an illustration of the
view which regards talent as a product of the hereditary
factors. Mr. Galton believed that heredity accounts for talent
and that it is so dominant in the lives of the talented that it
is bound to express itself as talent. In his estimation there
is no such thing as latent genius, because it is in the nature
of genius that it surmounts all obstacles. He says:

'By natural ability, I mean those qualities of intellect and
disposition, which urge and qualify a man to perform acts which
lead to reputation. I do not mean capacity without zeal, nor
zeal without capacity, nor even a combination of both of them,
without an adequate power of doing a great deal of very
laborious work. But I mean a nature which, when left to itself,
will, urged by an inherent stimulus, climb the path that leads
to eminence, and has strength to reach the summit--one which,
if hindered or thwarted, will fret and strive until the
hindrance is overcome, and it is again free to follow its
labor-saving instinct.'[2]

[3] "Hereditary Genius," pp. 37-8.



This in reality amounts to saying that the genius is
omnipotent. Nothing can prevent the development of the genius.
He is master of all difficulties by the very fact that he is a
genius. It is also equivalent, by implication, to saying that
obstacles can have no qualifying effect on the course of such
an individual. A great difficulty is no more to him than a
small one. Hence no matter in what circumstances he lives he is
always bound to gain the maximum of his development. He could
not be either greater or less than he is, notwithstanding the
force of circumstances, whether obstructive or propitious. The
energy of a genius is thus differentiated from all other forms
of energy. Other forms of energy are modified in their course
and effects by preventing obstacles. Add to or subtract from
the impediments and the effect of the energy is changed by the
amount of the impediments. But this doctrine completely
emancipates human energy, when manifested in the form of
genius, from the working of the law of cause and effect.

It is especially noteworthy that it is not what we should
expect in view of the place and function of the environment in
the course of evolution. To say the least environment enjoys a
very respectable influence in selecting and directing the
forces of development. Some men have gone so far as to make the
external factors account for everything in society. Discounting
this claim, the minimum biological statement is that the
environment exercises a selective function relative to organic
forms and variations. It opposes itself to the transmission
strain, and if unfavorable to it, may eliminate it entirely. To
be able to accomplish this it must be regarded as having an
influence on all forms. And as there are all grades of
environment from the most unfavorable to the most propitious,
similarly constituted organisms living in those various
environments must perforce fare differently, some being
hindered others being promoted in varying degrees. That is,
should the most able by birth appear in the most unfavorable
environment they could not be expected to make the same gains
in life as similar congenitally able who appear in the most
favorable conditions.

Mr. Ward, on the contrary, holds that genius, like all other
forms of human ability, is the product of circumstances. It is
determined in its raw form by heredity, to be sure. In similar
circumstances it will affect more than the average man. But
like all other forms of energy it is subject to the law of
causality. It is not omnipotent so that it is able to set at
naught the effects of opposing forces. Nor can it develop in
the absence of nourishing circumstances. Deprive it of cultural
opportunities and it is like the sprout of the majestic tree
which is deprived of moisture, or the great river cut off from
the supply of snow and rain. In other words, it is a product of
all the factors at work in its being and environment, and the
internal can not manifest itself or its powers without the
presence of the external. Modify the external factors to a
perceptible degree and the individual is modified to the same
degree.

In seeking to find the factors which are accountable for the
development of talent Mr. Ward takes into consideration those
of the physical environment, the ethnological, the religious,
the local, the economic, the social, and the educational. Each
one of these items is given a searching examination as to its
force. I shall briefly deal with each of these in turn, giving
the import of the findings in each case and as many of the
basic facts as possible in a small space.

By a consideration of French regions by departments, provinces,
and principal sections, as to their yield of talent, the
physical environment was found to have had no perceptible
influence. The mountain-situated Geneva and the lowland Paris
produced alike prolifically talented men. The valley of the
Seine and that of the Loire competed for hegemony in fecundity.
The facts contradicted the highland theory, the lowland theory,
the coast theory, and every other theory of the dominance of
physical environment.

To get at the influence of the ethnological factor the Gaulic,
Cimbrian, Iberian, Ligurian and Belgic elements of the
population were examined as to their fecundity in talent. Odin
confesses to being unable to discover "the least connection
between races and fecundity in men of letters." Attention was
paid likewise to races speaking other than French language.
Again there was a conflict of facts. Inside of France
ethnological elements exerted "no appreciable influence upon
literary productivity." In Belgium and Lorraine, where the
German language dominated, it was found that French literature
mastered the situation, thus indicating that a common language
does not necessitate a common literature. The conclusion
ethnologically is that races possess an equality in yielding
talent.

The religious factor was found to have been more influential
formerly in bringing to light talent than at the close of the
five-hundred-year period. From 1300 to 1700 the church
furnished on the average 37.8 per cent. of all literary talent.
Its fecundity dropped to 29 in the period from 1700 to 1750.
Between 1750 and 1825 it produced but 6.5 of the talent. As
Galton has shown, eminent men were killed or driven out during
the period of religious persecution in Spain, France and Italy.
The celibacy of the clergy which gave undisturbed leisure may
have been an element in making the church productive in the
earlier years. On the other hand, the quieting effect of family
life of the protestant ministry seems to have had a propitious
influence in later times, as there appeared a relative increase
among protestant clergy of talent, while the output among the
catholic clergy continued to decline.

In this investigation the local environment appeared to have
the most influence in the production of talent. Odin gave
witness to having a suspicion that somewhere there was a
neglected factor. The facts connected talent with the cities in
an overwhelming manner. The statement that genius is the
product of the rural regions seems to have had no legs to stand
on. The majority of the talented were born in the cities and
practically all of them were connected with city life.

In proportion to population the cities produced 12.77, almost
thirteen times as many men of talent as rural regions. The
whole of France produced 6,382, the number selected by Odin as
the more meritorious of the men of letters. If all France had
been as productive as Paris it would have yielded 53,640; if as
fecund as the other chief cities, it would have produced
22,060; but if only as fertile as the country the number would
have fallen to 1,522.

It would seem that the matter of population has something to do
with the production of talent. Aggregations of population offer
frequent contact of persons, division of labor, competition
between individuals, a better coordination of society for
cooperative results, neutralization of physical qualities, and
the ascendancy of innovation over the conservative attitude. It
is not the mere density of population which is the effective
element. It is rather the dynamic density which is productive,
that is, the manifestation of the common life and spirit. City
life is specialized in structure and function, rendering men
more interdependent and cooperative. Specialization means moral
coalescence

The chateaux of France are very prolific in producing talent.
They yielded 2 per cent. of all the talent of the period,
seemingly out of proportion to their importance.

Why are certain of the cities and the chateaux more fertile
than most cities and the country in producing the talented? We
have a general reply in the statement as to the dynamic density
of cities. A further analysis finds those communities are
possessed of elements which the country does not have. Odin
calls them "properties." They are the location of the
political, administrative and judicial agencies of society;
they are in possession of great wealth and talent; they are
depositories of learning and the tools of information. The
avenues which open upon talent and the tools and agencies by
means of which the passage to it is to be made segregate
themselves in cities and towns

As the result of his investigation into the distribution of men
of science in the United States, Professor Cattell arrives at
nearly the same conclusion. He writes:

'The main factors in producing scientific and other forms of
intellectual performance seem to be density of population,
institutions and social traditions and ideals. All these may be
ultimately due to race, but, given the existing race, the
scientific productivity of the nation can be increased in
quantity, though not in quality, almost to the extent that we
wish to increase it.'[4]

[4] "American Men of Science," Second edition, p. 654.



It is interesting to note that nearly all of the women of
talent have been born in cities and chateaux. This means that
women had to be born where the means of development were to be
had, as they were not free to move about in society, as were
men.

Total             562          57, or 9 per cent.



The economic factor has been an important one in offering the
leisure which is necessary for the development of talent. Men
who have to use their time and energy wholly in the support of
themselves and families are deprived of the leisure which
productivity and creativeness in work demands. Of the French
men of letters 35 per cent. belonged to the wealthy or noble
class, 42 per cent. to the middle class, and 23 per cent. to
the working class. Odin was able to discover the economic
environment of 619 men of talent. They were distributed by
periods between the rich and poor as shown in the table on page
169.

Of one hundred foreign associates of the French Academy the
membership of the wealthy, middle and working classes were 41,
52 and 7. A combination of two other of Candole's tables yields
for those classes in per cents 35, 42 and 23. In ancient and
medieval times practically all of the talented came from the
wealthy class. On the whole, but about one eleventh of the men
of talent had to fight with economic adversity. But when we
remember that the wealthy class formed but a small portion of
the population in each period, probably not more than one
fourth, this means that as compared with members of the working
class individuals of the wealthy class had forty or fifty times
as good a chance of rising to a position of eminence. The
contrast is so sharp that Odin is led to exclaim, "Genius is in
things, not in man."

The social and the economic factors are so closely intertwined
that the influence of the social environment is already seen in
treating the economic. The social deals with matter of classes
and callings. The upper classes are of course the wealthier
classes so that the social and economic measures largely agree.
In Mr. Galton's inquiry into the callings of English men of
science which he made in 1873, it appears that out of 96
investigated 9 were noblemen or gentlemen, 18 government
officials, 34 professional men, 43 business men, 2 farmers and
1 other. Unless the one other was a working man the workers
produced none of these 96 men of science. Odin's classification
of the French men of letters gives to the nobility 25.5 per
cent., to government officials 20.0, liberal professions 23.0,
bourgeoise 11.6, manual laborers 9.8. Only a little over one
fifth of the talented were produced by the two lower classes.
Yet in numerical weight those classes constituted 90 per cent.
of the population. Data from four other European countries show
very much the same results, except that the workers and
bourgeoise classes make a better showing. It is unquestionable,
therefore, that the opportunities for developing talent or
genius are largely withheld from the working class and bestowed
on the upper classes.

We have yet one other factor to treat in the production of
talent, namely, the educational. The facts relative to the
education of the talented contradicts the assumption usually
made that genius depends on education and opportunity for none
of its success, but rises to its heights in spite of or without
them.

Of 827 men of talent (not merit class) Odin was able to
investigate as to their education he found that only 1.8 per
cent. had no education or a poor education, while 98.2 per
cent. had a good education. This number investigated was 73 per
cent. of all men of that class, and it is fair to assume that
about the same proportion of educated existed in the other 27
per cent. whose education was not known. Of the 16 of poor or
no education 13 were born in Paris, other large cities, or
chateaux, and three in other localities. Thus they had the
opportunities presented by the cities. Facts as to talented men
in Spain, Italy, England and Germany indicate that anywhere
from 92 to 98 per cent. have been highly educated, and probably
the latter per cent. is correct.

These figures can have but one meaning. They indicate that
talent and genius are dependent on educational and conventional
agencies of the cultural kind, as are other human beings for
their evolution. Otherwise we should expect the figures to be
reversed. If education and cultural opportunities count for
naught, then we should expect that, at a time when education
was by no means universal, the 90 or 98 per cent. Of genius
would mount on their eagle wings and soar to the summits of
eminence, clearing completely the conventional educational
devices which society had established.

Our conclusion, therefore, is that social and economic
opportunities afford the leisure as well as cultural advantages
for the improvement of talent; that the local environment is of
vital importance, offering as it does the cultural advantages
of cities of certain kinds and of chateaux, and that of the
local environment the educational facilities are of the
supremest importance. Consequently, it appears that Mr. Ward's
estimate of one person of talent to the 500 instead of Mr.
Galton's estimate of one to the 4,000 does not seem strained.
Produce in society generally the opportunities and advantages
which Geneva, Paris and the chateaux possessed and which gave
them their great fecundity in talent, and all regions and
places will yield up their potential or latent genius to
development and the ratio will be obtained.

This position is likely to be criticized, unless it is
remembered that we admit that there is a hereditary difference
at birth, and that all we seek to establish is that, given
these differences, what conditions are likely to mature and
develop the men of born talent. Thus after the appearance of my
"Vocational Education" I received a letter from Professor
Eugene Davenport in which he makes this statement:

'Ward's arguments as here employed seem to show that
environment is a powerful factor in bringing out talent even to
the exclusion of heredity. I doubt if you would care to be
understood to this limit, and yet where you enumerate on page
61 the reasons why certain cities are fecund in respective
talents, you seem to have overlooked the fact that if these
cities have been for many generations centers of talent to such
an extent as to provide exceptional environmental influences,
the same conditions would also provide exceptional parentage,
so that the birthrate of talent would be much higher in such a
region than the normal. In other words, the very same
conditions which would provide exceptional opportunities for
development also and at the same time provide an exceptional
birth condition. This is the rock on which very many arguments
tending to compare heredity and environment wreck
themselves.'[5]

[5] This is a criticism that needs to be met. Mr. George R.
Davies of this institution has submitted facts in a paper which
appeared in the March number of the Quarterly Journal of the
University of North Dakota, which fills in the gap. He shows
relative to American cities that there has been little or no
segregation of talented parentage.



We have arrived at a point where we are able to consider the
question of the conservation of talent. A position of advantage
has been gained from which to view this question. For we have
seen that talent has a decidedly important and indispensable
social function to perform. It is the creative and contributive
agency, the cause of achievement, and a vital factor in
progress. Its conservation is consequently devoutly to be
desired. We have also discovered the fact that, while a rare
commodity, it is present in society in a larger measure than we
have commonly believed. If progress is desirable in a measure
it is likely to be desirable in a large measure. If talent is
able to carry us forward at a certain rate with the development
of a minimum of the quantity that is in existence we should be
able to greatly accelerate our progress if all that is latent
could be developed and put into active operation. Further, we
have obtained some insight into the conditions which favor the
development of talent and likewise some of the obstacles to its
manifestation. If it abounds where certain conditions are
present in the situation and fails to appear where those
conditions are absent, we have a fertile suggestion as to the
method of social control and direction which will bring the
latent talent to fertility.

We must undoubtedly hold that if a larger supply of talent
exists than is discovered, developed and put to use that,
since, as we have seen, it is so valuable when estimated in
terms of social progress, we are dealing wastefully with
talent. We are allowing great ability to go to waste since we
are leaving it lie in its undeveloped form. Therefore one of
the problems of the proper conservation of talent consists in
finding a method of discovering and releasing this valuable
form of social energy.

When we come to inquire how this may be done, how this
discovery is to take place, we must take for our guide the
facts which were found to bear on the maturing of talent in the
above studies. We discovered that the local environment seemed
to contain the influential element in bringing forth talent.
When that local environment was analyzed it turned out that the
items of opportunity for leisure and the facilities for
education were the most fruitful factors. Leisure is absolutely
essential to afford that opportunity for self-development which
is required even of the most talented. This can only be had
when the income of the individual is sufficient to give him a
considerable part of his active time for carrying out his
intellectual aspirations. We have great numbers of people whom
we have reason to believe are as able on the average, have as
large a proportion of talent as the well-to-do, whose poverty
is so crushing and whose days of toil are so long and so
consuming of energy that the element of leisure is lacking. It
is only an occasional individual of this class of people who is
able to secure the wealth which means a measure of leisure by
which he is able to mount out of obscurity. An improvement in
the physical conditions of life of these people, together with
an increase in their economic possibilities is a necessary
means to the proper conservation of the talent of this group.

The cultural factor is one which must be made more omnipresent
than it is now before we shall be able to awake the latent
talent of the masses of people. There are certain sections of
all nations, and more especially of such nations as the United
States, where the population is widely scattered over vast
areas of farming regions in which the opportunities for
education and stimulative enterprises and institutions are
lacking or meager. The same is true of very large sections of
the populations of the cities. In both cases large
neighborhoods exist in which the lives of the people move in a
humdrum rut, never disturbed by matters which arouse the
creative element in human nature. Especially is this important
in the early years of life where the outlook for the whole
future of the individual is so strongly stamped. To come into
contact with no stimulus and arousing agent in the home, or the
neighborhood in the earliest years is to become settled into a
life-long habit of inert dullness.

When we revert to the schools which so generally abound, we
fail to find the stimulating element in them which might be
regarded as the necessary opportunity to develop talent. The
vast majority of elementary teachers are persons whose
intellectual natures have never been aroused. Their imaginative
and sympathetic capacities lie undeveloped. Their work in the
school is conducted on the basis of memory. It is parrot work
and ends in making parrots of the pupils. The rational and
causal as agencies in education are hardly ever appealed to.
Until our teaching force is itself developed in the directions
and capacities which alone characterize the intellectual we can
not hope for much in the way of recovering the rich field of
latent talent from its infertility.

Something remains to be said about the proper utilization of
talent which has been developed. Did all genius depend on the
hereditary factor and consequently we had developed all
individuals possessing exceptional ability into contributors
and creators, the question of their complete utilization by
society remains. That all able men and women are working at the
exact thing and in the exact place and under the exact methods
which will yield the greatest and most fruitful results for
society only the superficial could believe. Herbert Spencer
used up a very large part of his superb ability during the
larger portion of his life in the drudgery of making a living.
The work of the national eugenics laboratory of England is
carried on by a man of great talent, Professor Carl Pearson, in
cramped quarters and with insufficient equipment and support.
The enterprise is as important as any in England, that of
discovering the conditions and means of improving the human
race. The laboratory was built up in the first instance by the
sacrifice of Sir Francis Galton, and it is maintained by means
of the bequest of his personal fortune.

These are but instances of the many which exist where talented
individuals are working under great handicaps which neither
promote their talent nor secure fecundity of results to
collective man. In nearly every line of human endeavor gifted
individuals are consuming in an unnecessarily wasteful manner,
from the point of view of social improvement, their splendid
abilities. In educational institutions trained experts and
specialists are doing the work which very ordinary ability of a
merely clerical kind could conduct, sacrificing the higher and
more fruitful attainments thereby. I have known a faculty of
some forty members who were compelled to register the term
standings by sitting in a circle and calling off the grades of
several hundred students student by student and class by class
for each student as it came their turn, while a clerk recorded
the grades. The process consumed about ten hours per member
each term, or something over a thousand hours a year for the
whole faculty. Both economically and socially it was expensive
and wasteful because a cheap clerk could have done the whole
far better and have released the talent for productive
purposes.

We shall be wise when we realize the worth of our workable
talent and so establish its working conditions that it may
secure the full measure of its productiveness. If scientific
management for the mass of laborers of a nation is worth while
how much more serviceable would it be to extend its fructifying
influence to the most able members of the community.

But how to proceed in order to make the discovery of the latent
talent is the pressing problem. For a long time our methods
promise to be as empirical as are those we employ for the
advancement of science. Relative to the latter, after
enumerating a large list of conditions for promoting science of
which we are ignorant, Professor Cattell says:

'In the face of endless problems of this character we are as
empirical in our methods as the doctor of physic a hundred
years ago or the agricultural laborer to-day. It is surely time
for scientific men to apply scientific methods to determine the
circumstances that promote or hinder the advancement of
science.'[6]

[6] "American Men of Science," p. 565.



Since the discovery and utilization of genius and talent in
general are so closely related to the problem of the promotion
of science, his statement may be adopted to express the demand
existing in those directions.

THE complications behind the war in Europe are very many,
ruthless exploitation, heartless and brainless diplomacy,
futile dreams of national expansion (the "Mirage of the Map"),
of national enrichment through the use of force (the "Great
Illusion"), and withal a widespread vulgar belief in
indemnities or highway robberies as a means of enriching a
nation.

All these would represent only the unavoidable collision,
unrest and ambition of human nature, were it not that every
element involved in it was armed to the teeth. "When blood is
their argument" in matters of business or politics, all
rational interests are imperilled. The gray old strategists to
whom the control of armament was assigned saw the nations
moving towards peaceful solution of their real and imaginary
difficulties. The young men of Europe had visions of a broader
world, one cleared of lies and hate and the poison of an
ingrowing patriotism. After a generation of doubt and pessimism
in which world progress seemed to end in a blind sack, there
was rising a vision of continental cooperation, a glimpse of
the time when science, always international, should also
internationalize the art of living.

Clearly the close season for war was near at hand. The old men
found means to bring it on and in so doing to exploit the
patriotism, enthusiasm, devotion and love of adventure of the
young men of the whole world.

The use of fear and force as an argument in politics or in
business--this is war. It is a futile argument because of
itself it settles nothing. Its conclusion bears no certain
relation to its initial aim. It must end where it should begin,
with an agreement among the parties concerned. War is only the
blind negation, the denial of all law, and only the recognition
of the supremacy of some law can bring war to an end. In time
of war all laws are silent as are all efforts for progress, for
justice, for the betterment of human kind. If history were
written truthfully every page in the story of war would be left
blank, or printed black, with only fine white letters in the
darkness to mark the efforts for humanity, which war can never
wholly suppress.

In this paper I propose to consider only economic effects of
this war and with special reference to the great industry which
brings most of this audience together, the business of
insurance.

The great war debts of the nations of Europe began with
representative government. Kings borrowed money when they
could, bankrupting themselves at intervals and sometimes
wrecking their nations. Kings have always been uncertain pay.
Not many loaned money to them willingly and only in small
amounts and at usurious rates of interest. To float a
"patriotic loan," it was often necessary to make use of the
prison or the rack. With the advent of parliaments and chambers
of deputies, the credit of nations improved and it became easy
to borrow money. There was developed a special class of
financiers, the Rothschilds at their head, pawnbrokers rather
than bankers, men able and willing to take a whole nation into
pawn. And with the advent of great loans, as Goldwin Smith
wisely observed, "there was removed the last check on war."

With better social and business adjustments, and especially
with the progress of railways and steam navigation with other
applications of science to personal and national interests, the
process of borrowing became easier, as also the payment of
interest on which borrowing depends. Hence more borrowing,
always the easiest solution of any financial complication or
embarrassment. Through the substitution of regular methods of
taxation for the collection of tribute, the nations became
solidified. Only a solidified nation can borrow money. The
loose and lawless regions called Kingdoms and Empires under
feudalism were not nations at all. A nation is a region in
which the people are normally at peace among themselves. In
civil war, a nation's existence may be dissolved.

In all the ages war costs all that it can. All that can be
extorted or borrowed is cast into the melting pot, for the sake
of self-preservation or for the sake of victory. If the nations
had any more to give war would demand it. The king could
extort, but there are limits to extortion. The nation could
borrow, and to borrowing there is but one limit, that of actual
exhaustion.

Mr. H. Bell, cashier of Lloyd's Bank in London, said in 1913:

'The London bankers are not lending on the continent any more.
We can see already the handwriting on the wall and that spells
REPUDIATION. The people of Europe will say: "We know that we
have had all this money and that we ought to pay interest on
it. But we must live; and we can not live and pay."'

The chief motive for borrowing on the part of every nation has
been war or preparation for war. If it were not for war no
nation on earth need ever have borrowed a dollar. If provinces
and municipalities could use all the taxes their people pay,
for purposes of peace, they could pay off all their debts and
start free. In Europe, for the last hundred years, in time of
so-called peace, nations have paid more for war than for
anything else. It is not strange therefore that this armed
peace has "found its verification in war." It has been the "Dry
War," the "Race for the Abyss," which the gray old strategists
of the general staff have brought to final culmination.

The debt of Great Britain began with the revolution of 1869,
with about $1,250,000. This unpopular move, known as Dutch
finance, was the work of William of Orange. Other loans
followed, based on customs duties with "taxes on bachelors,
widows, marriages and funerals," and the profits on lotteries.
At the end of the war of the revolution the debt reached
$1,250,000,000, and with the gigantic borrowings of Pitt, in
the interest of the overthrow of Napoleon, the debt reached its
highest point, $4,430,000,000. The savings of peace duly
reduced this debt, but the Boer war, for which about
$800,000,000 was borrowed, swept these savings away. When the
present war began the national debt had been reduced to a
little less than $400,000,000 which sum a year of world war has
brought up to $10,000,000,000.

The debt of France dates from the French Revolution. Through
reckless management it soon rose to $700,000,000, which sum was
cut by paper money, confiscation and other repudiations to
$160,000,000. This process of easing the government at the
expense of the people spread consternation and bankruptcy far
and wide. A great program of public expenditure following the
costly war and its soon repaid indemnity raised the debt of
France to over $6,000,000,000. The interest alone amounted to
nearly $1,000,000,000. A year of the present war has brought
this debt to the unheard of figure of about $11,000,000,000.
Thus nearly two million bondholders and their families in and
out of France have become annual pensioners on the public
purse, in addition to all the pensioners produced by war.

Germany is still a very young nation and as an empire more
thrifty than her largest state. The imperial debt was in 1908 a
little over $1,000,000,000. The total debt of the empire and
the states combined was about $4,000,000,000 at the outbreak of
the war. It is now stated at about $9,000,000,000, a large part
of the increase being in the form of "patriotic" loans from
helpless corporations.

The small debt of the United States rose after the Civil War to
$2,773,000,000. It has been reduced to about $915,000,000,
proportionately less than in any other civilized nation. The
local debts of states and municipalities in this and other
countries are, however, very large and are steadily rising. As
Mr. E. S. Martin observes,

'We have long since passed the simple stage of living beyond
our incomes. We are engaged in living beyond the incomes of
generations to come.'

Let me illustrate by a supposititious example. A nation has an
expenditure of $100,000,000 a year. It raises the sum by
taxation of some sort and thus lives within its means. But
$100,000,000 is the interest on a much larger sum, let us say
$2,500,000,000. If instead of paying out a hundred million year
by year for expenses, we capitalize it, we may have immediately
at hand a sum twenty-five times as great. The interest on this
sum is the same as the annual expense account. Let us then
borrow $2,500,000,000 on which the interest charges are
$100,000,000 a year. But while paying these charges the nation
has the principal to live on for a generation. Half of it will
meet current expenses for a dozen years, and the other half is
at once available for public purposes, for dockyards, for
wharves, for fortresses, for public buildings and, above all,
for the ever-growing demands of military conscription and of
naval power. Meanwhile the nation is not standing still. In
these twelve years the progress of invention and of commerce
may have doubled the national income. There is then still
another $100,000,000 yearly to be added to the sum available
for running expenses. This again can be capitalized, another
$2,500,000,000 can be borrowed, not all at once perhaps, but
with due regard to the exigencies of banking and the temper of
the people. With repeated borrowings the rate of taxation
rises. Living on the principal sets a new fashion in
expenditure. The same fashion extends throughout the body
politic. Individuals, corporations, municipalities all live on
their principal.

The purchase of railways and other public utilities by the
government tends further to complicate the problems of national
debt. It is clear that this system of buying without paying can
not go on forever. The growth of wealth and population can not
keep step with borrowing, even though all funds were expended
for the actual needs of society. Of late years, war preparation
has come to take the lion's share of all funds, however
gathered, "consuming the fruits of progress." What the end
shall be, and by what forces it will be brought about, no one
can now say. This is still a very rich world, even though
insolvent and under control of its creditors. There is a
growing unrest among taxpayers. There would be a still greater
unrest if posterity could be heard from, for it can only save
itself by new inventions and new exploitations or by frugality
of administration of which no nation gives an example to-day.

Nevertheless, this burden of past debt, with all its many
ramifications and its interest charges, is not the heaviest the
nations have placed on themselves. The annual cost of army and
navy in the world before the war was about double the sum of
interest paid on the bonded debt. This annual sum represented
preparation for future war, because in the intricacies of
modern warfare "hostilities must be begun" long before the
materialization of any enemy. In estimating the annual cost of
war, to the original interest of upwards of $1,500,000,000 we
must add yearly about $2,500,000,000 of actual expenditure for
fighters, guns and ships. We must further consider the generous
allowance some nations make for pensions. A large and
unestimated sum may also be added to the account from loss of
military conscription, again not counting the losses to society
through those forms of poverty which have their primal cause in
war. For in the words of Bastiat, "War is an ogre that devours
as much when he sleeps as when he is awake." It was Gambetta
who foretold that the final end of armament rivalry must be "a
beggar crouching by a barrack door."

When the great war began, the nations of Europe were thus waist
deep in debt, the total amount of national bonded indebtedness
being about $30,000,000,000, or nearly three times the total
sum of actual gold and silver, coined or not in all the world.
A year of war at the rate of $50,000,000 to $70,000,000 per day
has increased this indebtedness to nearly $50,000,000,000, the
bonds themselves rated at half or less their normal value,
while the actual financial loss through destruction of life and
property has been estimated at upwards of $40,000,000,000.

In "The Unseen Empire," the forceful and prophetic drama of Mr.
Atherton Brownell, the American ambassador, Stephan Channing,
tries to show the chancellor of Germany that war with Great
Britain is not a "good business proposition." He says:

'Our Civil War has cost us to date, if you count pensions for
the wrecks it left--mental and physical--nearly twenty billions
of dollars. And that doesn't include property losses, nor
destruction of trade, nor broken hearts and desolate
homes--that's just cold hard cash that we have actually paid
out. You can't even think it. There have been only about one
billion minutes since Christ was born. Now if there had been
four million slaves and we had bought every one of them at an
average of one thousand dollars apiece, set them free and had
no war, we should have been in pocket to day just sixteen
billion dollars. That one crime cost us in cash just about the
equal of sixteen dollars a minute from the beginning of the
Christian era.'

The war as forecast in the play is now on in fact, and one
certain truth in regard to it is that it is assuredly not "a
good business proposition" for anybody in any nation, excepting
of course, the makers of the instruments of death.

The actual war began, in accord with Professor Richet's
calculation, at a cost of $50,000,000 per day. Previous to this
the "dry war" or "armed peace" cost only $10,000,000 per day.
This is Richet's calculation in 1912, an underestimate as to
expenses on the sea and in the air. These with the growing
scarcity of bread and shrapnel, the equipment of automobiles,
and the unparalleled ruin of cities have raised this cost to
$70,000,000 per day.

This again takes no account of the waste of men and horses,
less costly than the other material of war and not necessarily
replaced. All this is piled on top of "the endless caravan of
ciphers" ($30,000,000,000), which represents the accumulated
and unpaid war debt of the nineteenth century.

War is indeed the sport for kings, but it is no sport for the
people who pay and die, and in the long run the workers of the
world must pay the cost of it. As Benjamin Franklin observed:

'War is not paid for in war time) the bill comes later.'

And what a bill!

Yves Guyot, the French economist, estimates that the first six
months of war cost western Europe in cash $5,400,000,000, to
which should be added further destruction estimated at
$11,600,000,000, making a total of $17,000,000,000. The entire
amount of coin in the world is less than $12,000,000,000. Edgar
Crammond, secretary of the Liverpool Stock Exchange, another
high authority, estimates the cash cost of a year of war, to
August 1, 1915, at $17,000,000,000, while other losses will
mount up to make a grand total of $46,000,000,000. Mr. Crammond
estimates that the cost to Great Britain for a year of war will
reach $3,500,000,000. This sum is about equivalent to the
accumulated war debt of Great Britain for a hundred years
before the war. The war debt of Germany (including Prussia) is
now about the same.

No one can have any conception of what $46,000,000,000 may be.
It is four times all the gold and silver in the world. It
represents, it is stated, about 100,000 tons of gold, and would
probably outweigh the Washington monument. We have no data as
to what monuments weigh, but we may try a few other
calculations. If this sum were measured out in $20 gold pieces
and they were placed side by side on the railway track, on each
rail, they would line with gold every line from New York to the
Pacific Ocean, and there would be enough left to cover each
rail of the Siberian railway from Vladivostock to Petrograd.
There would still be enough left to rehabilitate Belgium and to
buy the whole of Turkey, at her own valuation, wiping her
finally from the map.

Or we may figure in some other fashion. The average working man
in America earns $518 per year. It would take ninety million
years' work to pay the cost of the war; or ninety million
American laborers might pay it off in one year, if all their
living expenses were paid. The working men of Europe receive
from half to a third the wages in America. They are the ones
who have this bill to pay.

The cost of a year of the great war is a little greater than
the estimated value of all the property of the United States
west of Chicago. It is nearly equal to the total value of all
the property in Germany ($48,000,000,000) as figured in 1906.
The whole Russian Empire ($35,000,000,000) could have been
bought for a less sum before the war began. It could be had on
a cash sale for half that now. It would have paid for all the
property in Italy ($13,000,000,000); Japan ($10,000,000,000);
Holland ($5,000,000,000); Belgium ($7,000,000,000); Spain
($6,000,000,000) and Portugal ($2,500,000,000). It is three
times the entire yearly earnings in wages and salaries of the
people of the United States ($15,500,000,000).

We could go on indefinitely with this, playing with figures
which nobody can understand, for the greatest fortune ever
accumulated by man, in whatever fashion, would not pay for
three days of this war.

The cost of this war would pay the national debts of all the
nations in the world at the time the war broke out, and this
aggregate sum of $45,000,000,000 for the world was all
accumulated in the criminal stupidity of the wars of the
nineteenth century. If all the farms, farming lands, and
factories of the United States were wiped out of existence, the
cost of this war would more than replace them. If all the
personal and real property of half our nation were destroyed,
or if an earthquake of incredible dimensions should shake down
every house from the Atlantic to the Pacific, the waste would
be less than that involved in this war. And an elemental
catastrophe leaves behind it no costly legacy of hate; even the
financial troubles are not ended with the treaty of peace. The
credit of Europe is gone for one does not know how long. Before
the war, it is said, there were $200,000,000,000 in bonds and
stocks in circulation in Europe. Much of this has been sold for
whatever it would bring. Some of the rest is worth its face
value Some of it is worth nothing. In the final adjustment who
can know whether he is a banker or a beggar?

The American Ambassador was quite within bounds when he said:
"There isn't so much money in the world; you can't even think
it!"

Or we may calculate (with Dr. Edward T. Devine) in a totally
different way. The cost of this war would have covered every
moral social, economic and sanitary reform ever asked for in
the civilized world, in so far as money properly expended can
compass such results. It could eliminate infectious disease,
feeble-mindedness, the slums and the centers of vice. It could
provide adequate housing, continuity of labor, insurance
against accident; in other words it could abolish almost every
kind of suffering due to outside influences and not inherent in
the character of the person concerned.

A Russian writer, quoted by Dr. John H. Finley, puts this idea
in a different form:

'Our most awful enemies, the elements and germs and insect
destroyers, attack us every minute without cease, yet we murder
one another as if we were out of our senses. Death is ever on
the watch for us, and we think of nothing but to snatch a few
patches of land! About 5,000,000,000 days of work go every year
to the displacement of boundary lines. Think of what humanity
could obtain if that prodigious effort were devoted to fighting
our real enemies, the noxious species and our hostile
environment. We should conquer them in a few years. The entire
globe would turn into a model farm. Every plant would grow for
our use. The savage animals would disappear, and the infinitely
tiny animals would be reduced to impotence by hygiene and
cleanliness. The earth would be conducted according to our
convenience. In short, the day men realize who their worst
enemies are, they will form an alliance against them, they will
cease to murder one another like wild beasts from sheer folly.
Then they will be the true rulers of the planet, the lords of
creation.'

Says Robert L. Duffus:

'Money spent in warfare is not like spending money in other
industries. It will bring far more beastliness, far more
injustice, far more tyranny, far more danger to all that is
honorable, generous and noble in the world, far more grief and
rage than money spent in any other way. Not one per cent. of
the amount devoted to these purposes, is, for the end aimed at,
wasted.'

It is said that the main cause of the war lay in the envy of
German commerce by British rivals. This is assuredly not true.
But if it were, let us look at the business side of it. Taking
the net profits of over-seas trade as stated two years ago by
the Hamburg-American Company, the strongest in the world, and
estimating the rest, we have something like this:

During the "Dry War" the net earnings of the German Mercantile
fleet was about one third the cost of the navy supposed to
protect it. It would take seventy years of trade, on the scale
of the last year before the war, to repay Germany's expenses
for a year of war. To make good all the losses of Europe would
require more than one hundred years of the over-seas trading
profits of all the world. War is therefore death to trade, as
it is to every other agency of civilization.

At the beginning of the war the value of stocks and bonds in
circulation in Europe amounted to about $200,000,000,000. What
is the present value of all these certificates of ownership?
What is the present value of any particular industrial plant or
commercial venture?

A friend in London had inherited through his German wife a
large aniline dye plant on the Rhine. He told me recently that
he had not heard one word from it for six months. What will be
its value when he hears from it? And what certainty has he as
to its ownership?

Is it true that this war is the outcome of commercial jealousy?
Let us look at this for a moment. The two greatest shipping
companies in the world before the war were the Hamburg-American
Company and the Nord-Deutscher Lloyd of Bremen. These companies
had grown strong because they deserved to grow. They had
attended to their affairs both in shipment of freight and
transportation of passengers with that minute attention to
details which is so large an element in German success. The
growth of these companies arose through American trade and
especially through trade with Great Britain and the British
possessions. Did they clamor for war--a war, whatever else
might result, sure to cripple their trade for a generation. It
is said that Ballin, of the Hamburg Company, unable to prevent
Great Britain from rising to the defense of Belgium "went home
broken-hearted." Did Ballin build the great Imperator, costing
nine million--six million of it borrowed money--with a view of
laying her off after a few trips for an indefinite period in
Hamburg? Did the Nord-Deutscher Lloyd contemplate leaving the
Vaterland and the George Washington to lie in Hoboken till they
were sold for harbor dues?

Nor was the jealousy on the other side. The growth of German
commerce concerned mainly Great Britain. Presumably it was
profitable on both sides, for all trade is barter. In any
event, Great Britain has never raised a tariff wall against it,
never protected her traders by a single differential duty. She
has risen above the idea that by tariff exactions the
foreigners can be made to pay the sages. As for envy of German
commerce, who ever heard of an Englishman who envied anybody
anything?

Again, did the Cunard Company build her three great steamships,
the Mauretania, the Lusitania, the Aquitania for the fate which
has come to them? In 1914 I saw the great Aquitania, finest of
all floating palaces, tied by the nose to the wharf at
Liverpool, the most sheepish-looking steamship I ever saw
anywhere. Out of her had been taken $1,250,000 worth of plate
glass and plush velvet, elevators and lounging rooms, the
requirements of the tender rich in their six days upon the sea.
The whole ship was painted black, filled with coal--to be sent
out to help the warships at sea. And for this humble service I
am told she proved unfitted.

No, commercial envy is not a reason, rivalry in business is not
a reason, need of expansion is not a reason. These are excuses
only, not causes of war. There is no money in war. There is no
chance of highway robbery in the byways of history which can
repay anything tangible of the expense of the expedition. The
gray old strategists do not care for this. It is fair to them
to say they are not sordid. They care no more for the financial
exhaustion of a nation than for the slaughter of its young men.
"An old soldier like me," said Napoleon, "does not care a
tinker's damn for the death of a million men." Neither does he
care for the collapse of a million industrial corporations.

Of the many forms of business and financial relation among men,
none is more important than those included under the name of
insurance. Insurance is a form of mutual help. By its influence
the effects of calamity are spread so widely that they cease to
be felt as calamity. The fact of death can not be set aside,
but through insurance it need not appear as economic disaster,
only as personal loss. Its essential nature is that of social
cooperation and it furnishes some of the most effective of
bonds which knit society together. As insurance has become
already an international function, its influence should be felt
continuously on the side of peace. That it is so felt is the
justification of our meeting together to-day, as underwriters
of insurance and as workers for peace. The essence of
insurance, as Professor Royce observes, is that

'it is a principle at once peace-making in its general tendency
and business-like in its practicable special application.... As
a result of insurance, men gradually find themselves involved
in a social network of complicated but beneficent relations of
which individuals are usually very imperfectly aware but by
means of which modern society has been profoundly transformed.'


For life insurance, in general, is not personally selfish in
its motive. It is essentially altruistic, the effort of the
benefit of some person beloved who is designated as the
beneficiary. For the benefit of this surviving person, the
efforts involved in the payment of premiums are put forth, and
the insurance companies and their underwriters constitute the
machinery by which this unification is given to society.

To all the interests of insurance, the lawlessness of war is
wholly adverse and destructive. Insurance involves mutual trust
and trust thrives under security of person and property.
Insurance demands steadiness of purpose and continuity of law.
In war, all laws are silent. War is the brutish, blind, denial
of law, only admissible when all other honorable alternatives
have been withdrawn--the last resort of "murdered, mangled
liberty."

In its direct relation, war destroys those who to the
underwriter represent the "best risks," the men most valuable
to themselves and thus most valuable to the community. Those
whom war leaves behind, to slip along the lines of least
resistance into the city slums, are the people insurance rarely
reaches. War confuses administration of insurance. Policies, in
war time, can be written only on a sliding scale. This greatly
increases the premium by reducing the final payments. Increase
of rate of premium must decrease business. War means financial
anarchy, inflated currency and depreciation of bonds. A
currency which fluctuates demoralizes all business and war
leaves no alternative. The slogan "business as usual" in war
time deceives nobody. If it did, nobody would gain by the
deception. Enforced loans from the reserve fund of insurance
companies to the state mean the depreciation of reserves. The
substitution of unstable government bonds means robbery of the
bond holders. The yielding to the state, by enforced "voluntary
action," of reserves of savings banks and insurance companies
represents a form of state robbery. This is now in practice on
the continent of Europe. Such funds are probably never actually
confiscated but held in abeyance until the close of the war.
This is another form of the everpresent "military necessity,"
which seizes men's property with little more compunction than
it shows in seizing men's bodies. War conditions mean
insecurity of investment. In war, all bonds are liable to
become "scraps of paper," and no fund can be made safe. The
insurance investments in Europe have been enormously depleted
in worth, a reduction in market value estimated at 50 per cent.

Experts in insurance tell me that in war time certain policies
are written so as to be scaled down automatically when the
holder goes under the colors. Some are invalid in time of war,
and some have the clause of free travel greatly abridged. A few
are written to apply to all conditions, but on these the rates
of premiums would naturally increase. Companies generally
refuse to pay under conditions not nominated in the bond, and
in general all policies are automatically reduced to level of
war policies when war begins.

I am told that some American companies issue group policies as
for any or all of a thousand men, these not subject to a
physical examination. The war claims in Great Britain have been
very heavy, because such a large proportion of clerks,
artisans, students and other insurable or well-paid men have
been first to volunteer. Some insurance companies have been
much embarrassed by the general enlistment of their employees.

In fire insurance, conditions are much the same. All contracts
in foreign nations are held in abeyance until the close of war.
Such companies doing business in America are now mostly
incorporated as American.

In every regard, the business of insurance is naturally allied
with the forces that make for peace. War brings ruin, through
increase of loans, through the exhaustion of reserves and the
precarious nature of investment. The same remark applies in
some degree to every honorable or constructive business. If any
other form of danger threatened a great industry, its leaders
would be on the alert. They would spare no money and leave no
stone unturned for their own protection.

Towards war, business has always shown a stupid fatalism. War
has been thought "inevitable," coming of itself at intervals
with nobody responsible.

There could not be a greater error. War does not come of
itself, nor without great and persistent preparation. A few
hundred resolute men, bent on war, led by unscrupulous leaders
brought on this war. The military group of one nation plays
into the hands of like groups in other nations. To keep up war
agitation long enough, whether the cause be real or imaginary,
seems to hypnotize the public mind. The horrors of war
fascinate rather than repel, and thousands of men in this land
of peace are ready to fight in Europe to one who dreamed of
such a line of action a year or two ago.

"Eternal vigilance is the price of liberty." The interests
involved should put honest business on its guard. The insurance
men could afford to maintain a thousand observers, men wise in
business as well as in International Law, and in the manners
and customs of the people of the world. A few dozen skilful
politico-military detectives--men like W. J. Burns for example
employed in the interest of finance might save finance a
billion dollars. These should watch the standing incentives to
war. Such men should stand guard against the influences that
work toward conflict. Those who work for peace should be not
"firemen to be called in to put out the fire" already started
through the negligence of business men but agents for
"fireproof building material" in our national edifice, to stand
at all times for the security of business, the sanctity of law,
order and peace. This kind of "preparedness for war" would
involve no risks of conflict, of victory or defeat.



THE EVOLUTION OF THE STARS AND THE FORMATION OF THE EARTH. II

BY WILLIAM WALLACE CAMPBELL

DIRECTOR OF THE LICK OBSERVATORY, UNIVERSITY OF CALIFORNIA

EVIDENCE IN SUPPORT OF SEQUENCE PROPOSED

THERE are several lines of evidence in support of the order of
evolution which we have outlined.

1. The close relationship of the bright-line nebular spectrum,
the bright-line stellar spectrum and the spectra of the
simplest helium stars; the practically continuous sequence of
spectra from the helium stars to the red stars.

2. In the long run, we must expect the stars to grow colder, at
least as to the surface strata. What the average interior
temperatures are is another question; the highest interior
temperatures are thought to be reached at an intermediate or
quite late stage in the process, in accordance with principles
investigated by Lane and others; but the temperatures existing
in the deep interiors seem to have little direct influence in
defining the spectral characters of the stars, which are
concerned more directly with the surface strata.[1] We should
therefore expect the simpler types of spectra, such as we find
in the helium and hydrogen stars, in the early stages of the
evolutionary process. The complicated spectra of the metals,
and particularly the oxides of the metals, should be in
evidence late in stellar life, when the atmospheres of the
stars have become denser and colder.

[1] This important point seems not to have been realized by all
theorists.



3. The velocities of the Orion nebula, the Trifid nebula, the
Carina nebula, and of several other irregular nebulae, have
been measured with the spectroscope. These bodies seem to be
nearly at rest with reference to the stellar system. The helium
stars have the lowest-known stellar velocities, and the average
velocities of the stars are higher and higher as we pass from
the helium stars, through the hydrogen and solar stars, up to
the red stars. The average velocities of the brighter stars of
the different spectral classes, as determined with the D. O.
Mills spectrographs at Mount Hamilton and in Chile, are as in
the following table:

Spectral No. of  Class    Stars    Average Velocity in Space
   B                       225         12.9 km. per Sec.
   A                       177         21.9
   F                       185         28.7
   G                       128         29.9
   E                       382         33.6
   M                        73         34.3



We can not place the irregular nebulae after the red stars:
their velocities are too small, and their spectra have no
resemblances to the red-star spectra.

4. Wherever we find large irregular gaseous nebulae we find
stars in the early subdivisions of the helium group. They are
closely related in position. This is true of the Orion and
other similar regions. The irregular, gaseous nebulae are in
general found in and near the Milky Way, and so are the helium
stars. The yellow and red stars, at least the brighter ones, do
not cluster in nebulous regions.

5. The stars are more and more uniformly distributed over the
sphere as one goes from the helium stars through the hydrogen
and solar stars, to the red stars. The Class M stars show
little or no preference for the Milky Way. Of course, I am
speaking here of the brighter and nearer stars which we have
been able to study by means of the spectroscope, and not at all
of the faint stars which form the unstudied distant parts of
the Milky Way structure. The helium stars are young, their
motions are slow, and they have not wandered far from the place
of their birth. Not so with the older stars.

6. The visual double stars afford strong evidence that the
order of evolution described is correct. The 36-inch refractor
has shown that one star in 18, on the average, brighter than
the ninth visual magnitude, consists of two or more suns which
we can not doubt are in slow revolution around each other. The
number of double stars observable would be very much greater
than this if they were not so far away. Of the 20 stars which
we say are our nearest neighbors, 8 are well known double
stars; one double in each two and one half, on the average.
Aitken has made a specialty of observing the double stars whose
components in each case are very close together and are in
comparatively rapid revolution. His program includes 164 such
systems whose types of spectra are known, as in the following
table:

 Spectrum       Number of Double Stars
Bright-line            0
Class B                4
Class A-F            131
Class G-N             28
Class M-N?             1



The message which this table brings is clear. The double stars
whose spectra are of the Bright-Line and Class B varieties have
their components so close together that only 4, of Class B, are
visible. The great majority fall in Classes A to K; 159 out of
164. The component stars in these classes are far enough apart
to be visible in the telescopes, and yet are close enough to be
revolving in periods reasonably short. In the Class M double
stars, this program contains not more than one star, and I
believe the explanation is this: double stars of Class M are in
general so far apart, and therefore their periods of revolution
are so long, that they do not get upon programs of rapidly
revolving stars. Also, the fainter components in many red stars
must have cooled off so far that they are invisible. The
distances between the components of visual double stars are in
general the greater as we proceed from the helium stars through
the various spectral classes up to Class M. There are reasons
for believing that two stars revolving around their center of
mass have gradually increased their distance apart, and
therefore their revolution period. If this is true, the Classes
G and K; double stars are effectively older than Classes A and
F double stars, and these in turn are effectively older than
Class B double stars.

7. The spectrograph has great advantages over the telescope in
discovering and observing double stars whose components are
very close together, by virtue of the facts that the
spectrograph measures, velocities of approach and recession in
absolute units--so many kilometers per second--and that the
speeds of rotation in binary systems are higher the closer
together the two components are. The observations of the
brighter helium stars, especially those made at the Yerkes
Observatory by Frost and Adams, have shown that one helium star
in every two and one half on the average is a very close
double. In beta Cephei, an early Class B star, the components
are so close that they revolve around each other in 4 1/2
hours; many systems have periods in the neighborhood of a day,
of two days, of three days, and so on. Similar observations
made with the D. O. Mills spectrographs in both hemispheres
have shown that about one star in every four of the bright
stars, on the average, is a double star. In general, the
proportion of spectroscopic doubles discovered to date is
greatest in Class B and decreases as we proceed toward Class M.
The explanation is simple: in the Class B doubles the
components are close together, their orbital velocities are
very high and change rapidly, and the spectrograph is able to
discover the variations with little loss of time. As we pass
toward the yellow and red spectroscopic binaries we find the
components separated more and more, the orbital velocities are
smaller and the periods longer, the variations of velocity are
more difficult to discover, and in the wider pairs we must wait
many years before the variations become appreciable. There is a
very marked progression of the average lengths of periods of
the spectrographic double stars as we pass from the Class B to
the Class M pairs. Similarly, the eccentricities of the orbits
of the binaries increase as we proceed in the same direction.
Accumulating evidence is to the effect that the proportion of
double stars to single stars may be as great in the Classes A
to K as in Class B.

8. Kapteyn believes that he is able to divide the individual
stars--those whose proper motions are known--into the two star
streams which he has described; and he finds that the first
stream is rich in the early blue stars, less rich relatively in
yellow stars, and poor in red stars, whereas the second stream
is very poor in early blue stars, rich in yellows, and
relatively very rich in reds. His interpretation is that the
stream-one stars are effectively younger than the stream-two
stars, on the whole. Stream one still abounds in youthful
stars: they grow older and the yellow and red stars will then
predominate. Stream two abounds in stars which were once young,
but are now middle-aged and old.

The eight lines of argument outlined are in harmony to the
effect that there is a sequence of development from nebulae to
red stars.

The extremely red stars are all faint, only a very few being
visible to the naked eye, and these near the limit of vision.
Our knowledge concerning them is relatively limited. That
these, and all stars, will become invisible to our telescopes,
and ultimately be dark unshining bodies, is the logical
conclusion to which the evolutionary processes will lead. As I
have already stated, both Newcomb and Kelvin were inclined to
believe that the major part of gravitational matter in the
universe is already invisible.

It should be said that a few astronomers doubt whether the
order of evolution is so clearly defined as I have outlined it;
in fact, whether we know even the main trend of the
evolutionary process. We occasionally encounter the opinion
that the subject is still so unsettled as not to let us say
whether the helium stars are effectively young or the red stars
are effectively old. Lockyer and Russell have proposed
hypotheses in which the order of evolutionary sequence begins
with comparatively cool red stars and proceeds through the
yellow stars to the very hot blue stars, and thence back
through the yellow stars to cool red stars.

I think the essentially unanimous view of astronomers is to the
effect that the great mass of accumulated evidence favors the
order of evolution which I have described. We are all ready to
admit that there are apparent exceptions to the simple course
laid down, but that these exceptions are revolutionary in
effect, and not hopeless of removal, has not yet, in my
opinion, been established.

PHYSICAL CONDITIONS GOVERN APPEARANCES OF SPECTRA

A question frequently asked is this: if the yellow and red
stars have been developed from the blue stars, why do not the
thousands of lines in the spectra of the yellow and red stars
show in the spectra of the blue stars? Indeed, why do not the
elements so conspicuously present in the atmosphere of the red
stars show in the spectra of the gaseous nebulae? The answer is
that the conditions in the nebulae and in the youngest stars
are such that only the SIMPLEST ELEMENTS, like hydrogen and
helium, and in the nebulae nebulium, which we think are nearest
to the elemental state of matter, seem to be able to form or
exist in them; and the temperature must lower, or other
conditions change to the conditions existing in the older
stars, before what we may call the more complicated elements
can construct themselves out of the more elemental forms of
matter. The oxides of titanium and of carbon found in the red
stars, where the surface temperatures must be relatively low,
would dissociate themselves into more elemental components and
lose their identity if the temperature and other conditions
were changed back to those of the early helium stars. Lockyer's
name is closely connected with this phenomenon of dissociation.
There is no evidence, to the best of my knowledge, that the
elements known in our Earth are not essentially universal in
distribution, either in the forms which the elements have in
the Earth, or dissociated into simpler forms wherever the
temperatures or other conditions make dissociations possible
and unavoidable.

The meteorites, which have come through the atmosphere to the
Earth's surface, contain at least 25 known terrestrial
elements. That they have not been found thus far to contain all
of our elements is not surprising, for we should have
difficulty in finding a piece of our Earth weighing a few
kilograms which would contain 25 of our elements. We have not
found any elements in meteorites which are unknown to our
chemists. Our comets, which ordinarily show the presence of not
more than three elements, carbon, nitrogen and oxygen, give
certain evidence of sodium in their composition when they
approach fairly near to the Sun; and the great comet of 1882,
when very close to the Sun, developed in its spectrum many
bright lines not previously seen in comet spectra, which
Copeland said were due to iron. That the comets do not show a
greater number of elements is not in the least surprising: they
are not condensed bodies, and we think that their average
temperature is low, too low generally to develop the luminous
vapors of the more refractory elements. If their temperatures,
approximated those which exist in the stars, their spectra
would probably reveal the presence of many of the elements
which exist in the meteorites. Of course the proof of this is
lacking.

DESTINY OF THE STELLAR SYSTEM

We have said that the evolutionary processes depend primarily
upon the loss of heat. This is to the best of our knowledge a
genuine loss, except as some of the heat rays happen to strike
other celestial bodies. The flow of heat energy from a star
must be essentially continuous, always in one direction from
hotter bodies to colder bodies, or into so-called unending and
heatless space. Temperatures throughout the universe are
apparently moving toward uniformity, at the level of absolute
zero. Now, this uniformity would mean universal stagnation and
death. It is possible to have life and to do work only when
there are differences of temperature between the bodies
concerned: work is done or accompanied by a flow of heat,
always from the hotter to the colder body. We are not aware
that any compensating principle exists. Several students of the
subject, notably Arrhenius, have searched for such a principle,
a fountain of youth so to speak, in accordance with which the
vigor of stellar life should maintain itself from the beginning
of time to the end of time; but I think that nothing
approaching a satisfactory theory has yet been formulated. The
stellar universe seems, from our present point of view, to be
slowly "running down." The processes will not end, however,
when all the heat generable WITHIN the stars shall have been
radiated into an endless space. Every body within the universe,
it is conceivable, could have cooled down to absolute zero, but
the system might still be in its youth. So long as the stars,
whether intensely hot or free from all heat, are rotating
rapidly on their axes or are rushing through space with high
speeds, the system will remain VERY MUCH ALIVE. Collisions or
very close approaches of two stars are bound to occur sooner or
later, whether the stars are hot or cold, and in all such cases
a large share of the kinetic energy--the energy of motion--of
the two bodies will be converted into heat. A collision, under
average stellar conditions, should convert the two stars into a
luminous gaseous nebula, or two or more nebulae, which would
require hundreds or thousands of millions of years to evolve
again into young stars, middle-aged stars, old stars, and stars
absolutely cold. So long as any of these bodies retain motion
with reference to other bodies, they retain the power of
rebirth and another life. Not to go too far into speculative
detail, the general effect of these processes would be the
destruction of relative motions and the gradual decrease in the
number of separate bodies, through coalescence. Assume further,
however, that all existing bodies, widely scattered through the
stellar system, are absolutely cold and absolutely at rest with
reference to each other: the system might even then be only
middle-aged. The mutual gravitations of the bodies would still
be operative. They would pass each other closely, or collide,
under high generated velocities: there would be new nebulae,
and new and vigorous stellar life to continue through other
long ages. The system would not run down until all the kinetic
energy had been converted into heat, and all the heat generable
had been dissipated. This would not occur until all material in
the universe had been combined into one body, or into two
bodies in mutual revolution. However, if there are those who
say that the universe in action is eternal, through the
operation of compensating principles as yet undiscovered, no
man of science is at present equipped to prove the contrary.

THE NOVAE

The so-called new stars, otherwise known as temporary stars or
novae, present interesting considerations. These are stars
which suddenly flash out at points where previously no star was
known to exist; or, in a few cases, where a faint existing star
has in a few days become immensely brighter. Twenty-nine new
stars have been observed from the year 1572 to date; 19 of them
since 1886, when the photographic dry plate was applied
systematically to the mapping of the heavens, and 15 of the 19
stand to the credit of the Harvard observers. This is an
average of one new star in two years; and as some novae must
come and go unseen it is evident that they are by no means rare
objects. Novae pass through a series of evolutions which have
many points in common; in fact, the ones which have been
extensively studied by photometer and spectrograph have had
histories with so many identities that we are coming to look
upon them as standard products of evolutionary processes. These
stars usually rise to maximum brilliancy in a few days: some of
the most noted ones increased in brightness ten-thousand-fold
in two or three days. All of them fluctuate in brightness
irregularly, and usually in short periods of time. Several
novae have become invisible to the naked eye at the end of a
few weeks. With two or three exceptions, all have become
invisible in moderate-sized telescopes, or have become very
faint, within a few months. Two novae, found very early in
their development, had at first dark line spectra, a night
later bright lines appeared, and a night or two later the
spectra contained the broad radiation and absorption bands
characteristic of all recent novae. After the novae become
fairly faint, the bright lines of the gaseous nebula spectrum
are seen for the first time. These lines increase in relative
brilliancy until the spectra are essentially the same as those
of well-known nebulae, except that the novae lines are broad
whereas the lines of the nebulae are narrow. In a few months or
years the nebular lines diminish in brightness, and the
continuous spectrum develops. Hartmann at Potsdam, and Adams
and Pease with the 60-inch Mount Wilson reflector, have shown
that the spectra of the faint remnants of four originally
brilliant novae now contain some of the bright lines which are
characteristic of Wolf-Rayet stars.[2]

[2] After this lecture was delivered Adams of Mount Wilson
reported that in November, 1914, the chief nebular line (5007A)
and another prominent nebular line (4363A) had entirely
disappeared from the spectrum of Nova Geminorum No. 2, whereas
the second nebular line in the green (4959A) remained strong;
probably a step in progress from the nebular to the Wolf-Rayet
spectrum.



Why the novae suddenly flare up, and what their relations to
other celestial bodies may be, are questions which can not be
regarded as settled. Their distribution on the celestial sphere
is indicated in Figure 25 by the open circles. In this figure
the densest parts of the Milky Way are drawn in outline. All of
the novae have appeared in the Milky Way, with the exception of
five: and these exceptions are worthy of note. One of the five
appeared in the condensed nucleus of the great Andromeda
nebula, not far from its center; another (zeta Centauri) was
located close to the edge of a spiral nebula and quite possibly
in a faint outlying part of the nebula; a third (tau Coronae)
was observed to have a nebulous halo about it at the earliest
stage of its observed existence; a fourth (tau Scorpii)
appeared in a nebula; and the fifth (Nova Ophiuchi No. 2) in
1848 was not extensively observed. The other 24 novae appeared
within the structure of the Milky Way. Keeping the story as
short as possible, a nova is seemingly best explained on the
theory that a dark or relatively dark star, traveling rapidly
through space, has encountered resistance, such as a great
nebula or cloud of particles would afford. While passing
through the cloud the forward face of the star is bombarded at
high velocities by the resisting materials. The surface strata
become heated, the luminosity of the star increases rapidly.
The effect of the bombardment by small particles can be only
skin deep, and the brightness of the star should diminish
rapidly and therefore the spectrum change speedily from one
type to another. The new star of February, 1901, in Perseus,
afforded evidence of great strength on this question. Wolf at
Heidelberg photographed in August an irregular nebulous object
near the nova. Ritchey's photograph of September showed
extensive areas of nebulosity around the star. In October
Perrine and Ritchey discovered that the nebular structure had
apparently moved outward from the nova, from September to
October. Going back to a March 29th photograph taken for a
different purpose, Perrine found an irregular ring of
nebulosity closely surrounding the star. Apparently, the region
was full f nebulosity which is normally invisible to us. The
rushing of the star through this resisting medium made the star
the brightest one in the northern sky for two or three days.
The great wave of light going out from the star when at its
brightest traveled in five weeks as far as the ring of
nebulosity, where, falling upon non-luminous nebulous
materials, it made the ring visible. Continuing its progress,
the wave of light illuminated the material which Wolf
photographed in August, the materials which Ritchey
photographed still farther away in September, and the still
more distant materials which Perrine and Ritchey photographed
in October, November, and later. We were able to see this
material only as the very strong wave of light which left the
star at maximum brightness made the material luminous in
passing. That 24 novae should occur in the Milky Way, where the
stars are most numerous, and where the resisting materials may
preferably prevail, is not surprising; and it should be
repeated that at least three of the five occurring outside of
the Milky Way were located in nebulous surroundings.

The actual collision of two stars would necessarily be too
violent in its effect to let the reduction of brilliancy occur
so rapidly as to cause the disappearance of the nova in a few
weeks or months. The close approach of two stars might
conceivably produce the observed facts, but even this process
seems too violent in its probable results. The chances for the
collision of a rapidly traveling star with an enormously
extended nebulous cloud are vastly greater, and the apparent
mildness of the phenomenon observed is in better harmony with
expectation.

RELATION OF NOVAE, PLANETARY NEBULAE AND WOLF-RAYET STARS

Although all recent novae have been observed to become
planetary or stellar nebulae, they seem not to remain nebular
for any length of time; they have gone further and become
Wolf-Rayet stars. Whether any or all of the planetary nebulae
that have been known since Herschel's day, and have remained
apparently unchanged in form, have developed from new stars, is
uncertain and doubtful. If they have, the disturbances which
gave them their character must have been violent, such as would
result from full or glancing collisions of two stars, in order
to produce deep-seated effects which change slowly, rather than
surface effects which change rapidly.

Whether the Wolf-Rayet stars have in general been formed from
planetary nebulae is a different question: some of them
certainly have. Wright has recently shown that the stellar
nuclei of planetary nebulae are Wolf-Rayet stars, and he has
formulated several steps in the process whereby the nebulosity
in a planetary eventually condenses into the central star. The
distribution of the planetaries and the Wolf-Rayet stars on the
sphere affords further evidence of a connection. We saw. that
the novae are nearly all in the Milky Way. The irregular, ring,
planetary and stellar nebulae, plotted in Fig. 27, prefer the
Milky Way, but not so markedly. The Wolf-Rayets, without
exception, are located in the Milky Way and in the Magellanic
Clouds, and those in the Milky Way are remarkably near to its
central plane. 107 of these objects are known, 1 is in the
Lesser Magellanic Cloud, and 21 are in the Greater Magellanic
Cloud. The remaining 85 average less than 2 3/4 degrees from
the central plane of the Milky Way.

We are obliged to say that the places of the novae, of the
planetary and stellar nebulae, and of the Wolf-Rayets in the
evolutionary process are not certainly known. If the Wolf-Rayet
stars have developed from the planetaries, the planetaries from
the novae, and the novae have resulted from the close approach
or collision of two stars, or from the rushing of a dark or
faint star through a resisting medium, then the novae,
planetaries and Wolf-Rayets belong to a new and second
generation: they were born under exceptional conditions. The
velocities of the planetary nebulae seem to be an insuperable
difficulty in the way of placing them between the irregular
nebulae and the helium stars. The average radial velocity of 47
planetary nebulae is about 45 km. per second; and, if the
motions of the planetaries are somewhat at random, their
average velocities in space are twice as great, or 90 km. per
second. This is fully seven times the average velocity of the
helium stars, and the helium stars in general, therefore, could
not have come from planetary nebulae. The radial velocities of
only three Wolf-Rayet stars have been observed, and this number
is too small to have statistical value, but the average for the
three is several times as high as the average for the helium
stars. We can not say, I think, that the velocities of any
novae are certainly known.

If the planetaries have been formed from novae, especially the
novae which encountered the fiercest resistance, the high
velocities are in a sense not surprising, for those stars which
travel with abnormally high speeds are the ones whose chances
for collisions with resisting media are best; and, further, the
higher the speeds of collision the more violent the
disturbance. This line of argument also leads to the conclusion
that the novae, planetaries and Wolf-Rayets belong not in
general before the helium stars, but to another generation of
stars. They may, and I think will, develop into a small class
of helium stars having special characteristics; for example,
high velocities.

KANT'S HYPOTHESIS

Immanuel Kant's writings, published principally in 1755, are in
many ways the most remarkable contributions to the literature
of stellar evolution yet made. Curiously, Kant's papers have
not been read by the text-book makers, except in a few cases.
We have already referred to his ideas on the Milky Way and on
comets. In his hypothesis of the origin of the solar system, he
laid emphasis upon the facts that the six known planets revolve
around the Sun from west to east, nearly in the same plane and
nearly in the plane of the Sun's equator; that the then four
known moons of Jupiter, the five known moons of Saturn, and our
moon revolve around these planets from west to east, and nearly
in the same general plane; and that the Sun, our moon and the
planets, so far as known, rotate in the same direction. These
facts, he said, indicate indisputably a common origin for all
the members of the solar system. He expressed the belief that
the materials now composing the solar system were originally
scattered widely throughout the system, and in an elemental
state. This was a half century before Herschel's extensive
observations of nebuae. Kant thought of this elemental matter
as cold, endowed with gravitational power, and endowed
necessarily with some repulsive power, such as exists in gases.
He started his solar system from materials at rest. Most of the
matter, he said, drifted to the center to form the Sun. He
believed that nuclei or centers of attraction formed here and
there throughout the chaotic structure, and that in the course
of ages these centers grew by accretion of surrounding matter
into the present planets and their satellites; and that in some
manner motion in one direction prevailed throughout the whole
system. Kant's explanation of the origin of the ROTATION of the
solar system is unsound and worthless. We now know that such a
cloud of matter, free from rotation, could not of itself
generate rotation; it must get the start from outside forces.
Kant's false reasoning was due in part to the fact that some of
our most important dynamical laws were not yet discovered, in
part to his faulty comprehension of certain dynamical
principles already known, and probably in part to the
unsatisfactory state of chemical knowledge existing at that
date. This was half a century before Dalton's atomic theory of
matter was proposed.

Kant asserted that the processes of combination of surrounding
cold materials would generate heat, and, therefore, that the
resulting planetary masses would assume the liquid form; that
Jupiter and Saturn are now in the liquid state; and that all
the planets will ultimately become cold and solid. This is in
fair agreement with present-day opinion as to the planets, save
that modern astronomers go further in holding that the outer
strata of Jupiter and Saturn, likewise of Uranus and Neptune,
down to a great depth, must still be gaseous. In 1785, after
the principle of heat liberation attending the compression of a
gas had been announced, Kant supplemented his statement of 1755
as to the origin of the Sun's heat. He attributed this to
gravitational action of the Sun upon its own matter, causing it
to contract in size: he said the quantity of heat generated in
a given time would be a function of the Sun's volumes at the
beginning and at the ending of that period of time. This is
substantially the principle which Helmholtz rediscovered and
announced in 1854, and which is now universally accepted--with
the reservation of the past ten years, that radioactive
substances in the Sun may be an additional factor in the
problem.

Kant's paper of 1754 enunciated the theory that the Moon always
turns the same face to the Earth because of tidal retardation
of the Moon's rotation by the Earth's gravitational attraction;
and that our Earth tides produced by the Moon will slow down
the Earth's rotation until the Earth will finally turn one
hemisphere constantly to the Moon. This principle was in part
reannounced by Laplace a half century later, and likewise
investigated by Helmholtz in 1854, before Kant's work was
recognized.

Kant's speculations on a possible destruction and re-birth of
the solar system, on the nature of Saturn's ring, and on the
nature of the zodiacal light are similar in several regards to
present-day beliefs.

Kant wrote:

'I seek to evolve the present state of the universe from the
simplest condition of nature by means of mechanical laws
alone.'

In 1869 Sir William Thomson, afterwards Lord Kelvin, commented
that Kant's

'attempt to account for the constitution and mechanical origin
of the universe on Newtonian principles only wanted the
knowledge of thermodynamics, which the subsequent experiments
of Davy, Rumford and Joule supplied, to lead to thoroughly
definite explanation of all that is known regarding the present
actions and temperatures of the Earth and of the Sun and all
other heavenly bodies.'

These are, apparently, the enthusiastic comments resulting from
the re-discovery of Kant's papers. A present-day writer would
not speak so decisively of them, but we must all bow in
acknowledgment of Kant's remarkable contributions to our
subject, published when he was but 31 years old.

LAPLACE'S HYPOTHESIS

In 1796, 41 years following Kant's principal contributions,
Laplace published an extensive untechnical volume on general
astronomy. At the end of the volume he appended seven short
notes. The final note, to which he gave the curious title "Note
VII and last," proposed a theory of the origin and evolution of
the solar system which soon came to be known as Laplace's
Nebular Hypothesis. There are several circumstances which
indicate pretty clearly that Laplace was not deeply serious in
proposing this hypothesis:

1. Its method of publication as the final short appendix to a
large volume on general astronomy.

2. He himself said in his note that the hypothesis must be
received "with the distrust with which everything should be
regarded that is not the result of observation or calculation."

3. So far as we know he did not submit the theory to the test
of well-known mathematical principles involved, although this
was his habit in essentially every other branch of astronomy.

4. Laplace, in common with Kant, laid great stress upon the
fact that the satellites all revolve around their planets from
west to east, nearly in the common plane of the solar system;
yet 6 or 7 years before Laplace's publication, Herschel had
shown and published that the two recently discovered satellites
of Uranus were revolving about Uranus in a plane making an
angle of 98 degrees with the common plane of the solar system.
While Laplace might not have known of Uranus's satellites in
1796, on account of existing political conditions, there is no
evidence that he considered or took note of the fact when
making minor changes in his published papers up to the time of
his death in 1827. It is a further interesting comment on
international scientific literature that Laplace died without
learning that Kant had worked in the same field.

Laplace and his contemporary, Sir William Herschel, had been
the most fruitful contributors to astronomical knowledge since
the days of Sir Isaac Newton. Herschel's observations had led
him to speculate as to the evolution of the stars from nebulae,
and as a result interest in the subject was widespread. This
fact, coupled with Laplace's commanding position, caused the
nebular hypothesis to be received with great favor. During an
entire century it was the central idea about which astronomical
thought revolved.

Laplace conceived that the solar system has been evolved from a
gaseous and hot nebula; that the nebulosity extended out
farther than the known planets; and that the entire nebulous
mass was endowed with a slow rotation that was UNIFORM IN
ANGULAR RATE, as in the case of a rotating solid. This gaseous
mass was in equilibrium under the expanding forces of heat and
rotation and the contracting force of gravitation. Loss of heat
by radiation permitted corresponding contraction in size, and
increased speed of rotation. A time came, according to Laplace,
when the nebula was rotating so rapidly that an outer ring of
nebulosity was in equilibrium under centrifugal and
gravitational forces and refused to be drawn closer in toward
the center. This ring, ROTATING AS A SOLID, maintained its
position, while the inner mass contracted farther. Later
another ring was abandoned in the same manner; and so on, ring
after ring, until only the central nucleus was left. Inasmuch
as the nebulosity in the rings was not uniformly distributed,
each ring broke into pieces, and the pieces of each ring, in
the progress of time, condensed into a gaseous mass. The
several large masses formed from the abandoned rings,
respectively, became the planets and satellites of the solar
system. These gaseous masses rotated faster and faster as their
heat radiated into space, they abandoned rings of gaseous
matter just as the original mass had done, and these secondary
rings condensed to form the satellites; save that, in one case,
the ring of gas nearest to Saturn for some reason formed a
solid (!) ring about that planet, instead of condensing into
one or more satellites. Thus, in outline, according to Laplace,
the solar system was formed.

The first half of the nineteenth century found the nebular
hypothesis accepted almost without question, but a tearing-down
process began in the second half of the century, and at present
not much of the original structure remains standing. This is
due in small part to discoveries since Laplace's time, but
chiefly to a more careful consideration of the fundamental
principles involved. We have space to present only a few of the
more salient objections.

1. If the materials of the solar system existed as a gas,
uniformly distributed throughout what we may call the volume of
the system, the density of the gas would be exceedingly low: at
the most, several hundred million times less dense than the air
we breath. Conditions of equilibrium in so rare a medium would
require that the abandonment of the outer parts by the
contracting and more rapidly rotating inner mass should be a
continuous process. Each abandoned element would be abandoned
individually; it would not be vitally affected by the elements
slightly farther out in the structure, nor by the elements
slightly nearer to the center. Successive abandonment of nine
gaseous rings of matter, EACH RING ROTATING AS IF IT WERE A
SOLID STRUCTURE, is unthinkable. The real product of the
cooling process in such a nebula would undoubtedly be something
in the nature of a spiral nebula, in which the matter would
revolve around the nucleus the more rapidly the nearer it was
to the nucleus. If the matter were originally distributed
uniformly throughout the rotating structure, the spiral lines
might not be visible. If it were distributed irregularly, the
spiral form here and there could scarcely fail to be in
evidence to a distant observer.

2. Laplace held that the condensation of each ring would result
in one planet, rotating on its axis from west to east; this
apparently by virtue of the fact that in a ring rotating AS A
SOLID the outer edge travels more rapidly than the inner edge
does, and therefore, the west to east direction of rotation
must prevail in the planetary product. If now, as we firmly
believe, each constituent of such an attenuated ring must
rotate substantially independently of other constituents, those
nearer the inner edge of the ring will possess the higher
speeds of rotation, and the preponderance of kinetic energy in
the inner parts of the ring should give the resulting planetary
condensation a retrograde direction of rotation.

3. According to Laplace the satellites should all revolve
around their primaries from west to east. Eight of the
satellites do not follow this rule.

4. If the materials composing the inner ring of Saturn were
abandoned by the parent planet, as this planet contracted in
size and rotated ever more and more rapidly, then the ring
should revolve about the planet in a period considerably longer
than the planet period. The reverse is the fact. The rotation
period of the equatorial region of the planet itself is 10 h.
14 m., whereas the inner edge of the ring system revolves about
the planet once in about five hours.

5. The inner satellite of Mars revolves once in 7 h. 39 m.,
whereas Mars requires 24 h. 37 m. for one rotation. According
to the Nebular Hypothesis, the period of the satellite should
be the longer.

6. Laplace's hypothesis would seem to require that the orbits
of the planets be circular or very nearly so. The orbits of all
except Venus and Neptune are quite eccentric, and Mercury's
orbit, which should have the nearest approach to circularity,
is by far the most eccentric.

7. If the planetary rings were abandoned by centrifugal action,
we should expect the Sun to be rotating in the principal plane
of the planet system. The major planets, from Venus out to
Neptune, are revolving in nearly a common plane. The Sun,
containing 99 6/7 per cent. of all the material in the system,
has its equator inclined 7 degrees to the planet plane. This
discrepancy is a very serious and I think fatal objection to
Laplace's hypothesis, as Chamberlin has emphasized.

8. Laplace assumed a nebula whose form was a function of its
rotational speed, its gravitation, its internal heat, and,
although he does not so state, of its internal friction. He did
not distribute the matter within the nebula to conform in any
way to the distribution as we observe it to-day, but he let the
entire structure contract, following the loss of heat, until
the maintenance of equilibrium required the successive
abandoning of seven or eight rings. He mentions a central
condensation, but gives no further particulars. Thirty years
ago Fouche established clearly that the condensing of Laplace's
assumed nebula into the present solar system would involve the
violent breaking of the law known as the conservation of moment
of momentum. Fouche proved that a distribution of matter beyond
any conception of the subject by Laplace must be assumed. Fully
96 per cent. must be condensed in the central nucleus AT THE
OUTSET, and not more than 4 per cent. of the total mass must
lie outside of the nucleus and be widely distributed throughout
the volume of the solar system. Chamberlin puts the case very
strongly in another way. If the planet Mercury was abandoned as
a ring of nebulosity, the equatorial velocity of the remaining
central mass must at that time have been in the neighborhood of
45 km. per second, as this is the orbital speed of Mercury. If
the central mass condensed to the present size of the Sun, the
Sun's equatorial velocity of rotation should now be fully 400
km. per second, in accordance with the requirement of the rigid
law of constancy of moment of momentum. The Sun's actual
equatorial velocity is only 2 km. per second!

In several other respects the hypothesis of Laplace, as he
proposed it, fails to account for the facts as they are
observed to exist.

Poincare devoted his unique talents to the evolution problem
shortly before his death. He recognized that the Laplace
hypothesis is not tenable except upon such an assumed
distribution of matter as was defined by Fouche. Accepting this
modification, and extending the hypothesis to involve the
application of tidal interactions at many points throughout the
solar system, Poincare expresses the opinion that the Laplacian
hypothesis, of all those proposed, is still the one which best
accounts for the facts.[3] However, he does not utilize the
hypothesis of rings rotating as solids, for he finds it
necessary to conclude that the planetary masses in the
beginning must have had retrograde rotations. In the large
planetary masses of Jupiter and Saturn, for example, the
materials which form the outer retrograde satellites were
abandoned while the rotations were still retrograde, and when
the diameters of the planetary masses were several scores of
times their present diameters. In these extended masses the Sun
would create tidal waves, and here, as always, such waves would
exert a retarding effect upon the rotations. A time would come,
Poincare thought, when these planets would rotate once in a
revolution; that is, present the same face to the Sun; and this
is in fact a west to east rotation. Further contraction of the
planetary masses would give rise to increasing rotational
speeds in the west to east direction. The materials which form
the inner satellites of Jupiter and Saturn were abandoned
successively after the west to east direction of rotation had
become established. According to modifications of the same
theory, tidal retardation has slowed down Saturn's speed since
the abandonment of the materials which later condensed to form
the inner ring of that planet; or, possibly, the ring materials
encountered resistance after the planet abandoned them, with
the consequence that the ring drew in toward the planet and
increased its speed; and similarly in the case of Mars and its
inner satellite.

[3] Poincare has made the following interesting comments on
Laplace's hypothesis: "The oldest hypothesis is that of
Laplace; but its old age is vigorous and for its age it has not
too many wrinkles. In spite of the objections which have been
urged against it, in spite of the discoveries which astronomers
have made and which would indeed astonish Laplace himself, it
is always standing the strain, and it is the hypothesis which
best explains the facts; it is the hypothesis which responds
best to the question which Laplace endeavored to answer, Why
does order rule throughout the solar system, provided this
order is not due to chance? From time to time a breach opened
in the old edifice (the Laplace hypothesis); but the breach was
promptly repaired and the edifice has not fallen."



To me this modification of the Laplacian hypothesis is
unsatisfactory, for several reasons. To mention only one: if
Jupiter was a large gaseous mass extending out as far as the
8th and 9th satellites, the gaseous body was very highly
attenuated; friction in the outer strata would be essentially a
negligible quantity, and tidal retardation would not be very
effective; and it would be under just these conditions that
loss of heat from the planet should be most rapid and the rate
of increase of retrograde rotation resulting therefrom be
comparatively high. It would seem that the rotation of the
planet in the retrograde direction must have accelerated under
the contractional cause, rather than have decreased and
reversed in direction under an excessively feeble tidal cause.

The recognized weaknesses of Laplace's hypothesis have caused
many other hypotheses to be proposed in the past half century.
The hypotheses of Faye, Lockyer, du Ligondes, See, Arrhenius,
and Chamberlin and Moulton include many of the features of
Kant's or Laplace's hypotheses, but all of them advance and
develop other ideas. It is unfortunate that space limits do not
permit us to discuss the new features of each hypothesis.

(To be continued.)



PROGRESS AND PEACE

BY PROFESSOR ROBERT M. YERKES

HARVARD UNIVERSITY

LASTING peace among the nations of the earth we must regard as
of supreme moment, the discovery of the conditions thereof, as
most worthy of human effort. Physical struggle is no longer
accepted as either a necessary or a desirable means of settling
differences between individuals. Why, then, should it be
tolerated to-day in connection with national disagreements? To
admit the impossibility or the impracticability of universal
peace is to stigmatize our vaunted civilization as a failure.
Surely we will not, can not, humble ourselves by such an
admission until we have exhausted our energies in searching for
the conditions of national amity.

With my whole life I believe in the possibility and value of
worldwide friendliness and cooperation. I am writing to discuss
not the attainability or the merits of peace, but ways of
achieving it; not to criticize present activities on its
behalf, but to indicate the promise of a neglected approach and
to present a program which should, I believe, find its place in
the great "peace movement."

Must peace be achieved and maintained by brute strength,
regardless of sense and sentiment, or may it be gained through
intelligence, humanely used? Must the pathway thereto be paved
with human skulls, builded with infinite suffering and
sacrifice, or may it he charted by scientific inquiry and
builded by the joyous labor of mutual service and helpfulness?
Is it possible, in the light of the history of the races of
man, to doubt that we must place our dependence on intelligence
sympathetically employed, not on physical prowess? To me it
seems that peace must be achieved peacefully, not by the clash
of arms and bloodshed.

But even if we grant that science is our main hope, there
remains a choice of methods. On the one hand, there is the way
of material progress, physical discovery and feverish haste to
apply every new fact to armament; on the other, that of
biological research, social enlightenment, and ever-increasing
human understanding and sympathy.

Firm believers in each of these possible approaches, through
science, to international peace, are at hand. The one group
argues that nations, like individuals, must be controlled in
all supreme crises by fear; the other contends that
civilization has developed in enlightened human sympathy a
higher, a more worthy, and a safer control of behavior.

As a biologist and a believer in the brotherhood of man, I wish
to present the merits of sympathy, as contrasted with fear, and
to plead for larger attention to the biological approach to the
control of international relations. For I am convinced that the
greatest lesson of the present stupendous world-conflict is the
need of thorough knowledge of the laws of individual and social
human behavior. Surely this war clearly indicates that the
study of instinct, and the use of our knowledge for the control
of human relations, is incalculably more important for the
welfare of mankind than is the discovery of new and ever more
powerful explosives or the building of increasingly terrible
engines of destruction.

During the last half-century the physical sciences,
technologies, arts and industries, have made marvelous
advances. At enormous cost of labor and material resources
there have been discovered and perfected means of destroying
life and property at once so effective and so terrible to
contemplate that preparedness for war seemed a safe guarantee
of peace. But who is there now to insist, against the evidence
of blood-drenched Europe, that material progress, physical
discovery, and armament based thereupon, assure international
friendship?

Only if one of the nations should discover, and guard as its
secret, some diabolically horrible means of destroying human
life and property by wholesale and over materially unbridged
distances, can armaments even temporarily put an end to war. In
such event--and it is by no means an improbability--the whole
world might suddenly be made to bow in terror before the will
of the all-powerful nation. Before this approaching crisis, can
we do less than earnestly pray that the translation of physical
progress into armament may be halted until the brotherhood of
man has been further advanced? Dare we stop to contemplate what
would happen to-morrow if Germany, with half the civilized
world arrayed against her, should come into possession of some
imponderable, and to the untutored mind mysterious, means of
directing her torpedoes, exploding magazines, mines, shells
from distant bases? Undoubtedly we are close upon the
employment of certain vibrations for this deadly purpose. Shall
we veer in time and take a safer course, or are we doomed to
the inevitable?

For the certain result of pushing forward relentlessly on the
path of preparation for war--in the name of peace--is the
dominance of a single nation and the destruction or subjugation
of all others. This is as inevitable as is death. If we would
preserve and foster racial and national diversity of traits,
promote social individuality as we so eagerly foster the
diversity of selves, we must speedily focus attention upon
human nature and seek that knowledge of it which shall enable
us to control it wisely rather than to destroy it ruthlessly.

Even were I able to do so, I should in no degree belittle the
achievements of the physical sciences and their technologies,
for I believe whole-heartedly in their value, and long for the
steady increase of our power to control our environment. But
when these achievements are offered as means of creating or
maintaining certain desired conditions of individual and social
life, I must insist that other knowledge is essential--nay,
more essential--than that of the physicist or chemist.
Knowledge, namely, of life itself.

Most briefly, the situation may thus be described. In peace and
in war there are two large, complex and intricate groups of
facts to be dealt with by those who seek the welfare of man.
The one group comprises the phenomena of physical nature as the
condition of life--environment; the other is constituted by the
phenomena of life and the relations of lives. Those who
sincerely believe in preparedness for war as a preventive
measure, misconceive and attempt to misuse the emotion of fear
and its modes of expression. It is as though we should strive
tirelessly to develop machinery and methods for educating our
children, the while ignorant of the laws of child development
and branding as of no practical importance the fundamentals of
human nature.

To nations no more than to individuals is it given to live by
fear alone. By it a nation may become dominant, and diversity
of body, mind, and ideals be eradicated. To base our
civilization upon fear entails uniformity, monotony of life;
the sacrifice of peoples for the unduly exalted traits and
national ideals of a single homogeneous social group--a single
all-powerful nation. Knowledge of life, and the sympathy for
one's fellow men which springs from it, must control the world
if nations are to live in peaceful and mutually helpful
relations. If life, whether of the individual or of the social
group, is to be controlled, it must be through intimate
knowledge of life, not through knowledge of something else. The
world must be ruled by sympathy, based upon understanding,
insight, appreciation. This is my prophecy, this my faith and
my present thesis.

Material as contrasted with purely intellectual or spiritual
progress is the pride of our time. We worship technology as
reared upon physics and chemistry. But what is our gain, in
this progress, so long as we continue to use one another as
targets? Would it not be wiser, more far-sighted, more humane,
more favorable to the development of universal peace and
brotherhood, to give a large share of our time and substance to
the search for the secrets of life? As compared with the
physical sciences, the biological departments of inquiry are,
in general, backward and ill-supported. Why? Because their
tremendous importance is not generally recognized, and, still
more, because the control of inanimate nature as promised by
physical discovery and its applications appeals irresistibly
both to our imagination and to our greed. We long for
peace--because we are afraid of war--we long for the perfecting
of individual and social life, but much more intensely and
effectively we long for wealth, power and pleasure.

What I have already said and now repeat in other words is that
if we really desired above anything attainable on earth the
lasting peace of nations, we should diligently foster and
tirelessly pursue the sciences of life and seek to perfect and
exalt the varied arts and technologies which should be based
upon them. Experimental zoology and genetics; physiology and
hygiene; genetic psychology and education; anthropology and
ethnology; sociology and economics, would be held in as high
esteem and as ardently furthered as are the various physical
sciences and their technologies.

Does it not seem reasonable to claim that human behavior may be
intelligently controlled or directed only in the light of
intimate and exhaustive knowledge of the organism, its
processes, and its relations to its environment? If this be
true, how pitiably, how shamefully, inadequate is our knowledge
even of ourselves! How few are those who have a sound, although
meager, knowledge of the laws of heredity, of the primary facts
of human physiology, of the principles of hygiene, of the chief
facts and laws of mental life, including the fundamental
emotions and their corresponding instinctive modes of action,
the modifiability or educability of the individual and the
important relations of varied sorts of experience and conduct,
the laws of habit, the nature and role of the sentiments, the
unnumbered varieties of memory and ideation, the chief facts of
social life and their relations to individual experience and
behavior. Not one person in a thousand has a knowledge of life
and its conditions equal in adequacy for practical demands to
his knowledge of those aspects of physical nature with which he
is concerned in earning a livelihood. Even those of us who have
dedicated our lives to the study of life are humble before our
ignorance. But with a faith which can not be shaken, because we
have seen visions and dreamed dreams, we insist that the
knowledge which we seek and daily find is absolutely essential
for the perfecting of educational methods; for the development
of effective systems of bodily and mental hygiene; for the
discovery, fostering and maintenance of increasingly profitable
social relations and organizations. In a word, we believe that
biology, of all sciences, can and must lead us in the path of
social as contrasted with merely material progress; can and
ultimately will so alter the relations of nations that war
shall be as impossible as is peace to-day.

Fortunately the biologist may depend, in his efforts to further
the study of all aspects of life, not upon faith and hope
alone, but also upon works, for already physiology and
psychology have transformed our educational practices; and the
medical sciences given us a great and steadily increasing
measure of control over disease.

At least two men, as different in intellectual equipment,
habits of mind, and methods of inquiry as well could be, the
one an American, the other an Englishman, have heralded the
broadly comparative and genetic study of mind and behavior--let
us call it Genetic Psychology--as the promise of a new era for
civilization, because the essential condition of the
intelligent and effective regulation of life.

The one of these prophets among biologists, President G.
Stanley Hall, has lived to see his faith in the practical
importance of the intensive study of childhood and adolescence
justified by radical reforms in school and home. Hall should be
revered by all lovers of youth as the apostle to adolescents.
The other, Professor William McDougall, has done much to
convince the thinking world that all of the social sciences and
technologies must be grounded upon an adequate genetic
psychology--a genetic psychology which shall take as full and
intelligent account of behavior as of experience; of the life
of the ant, monkey, ape as of that of man; of the savage as of
civilized man; of the infant, child, adolescent as of the
adult; of the moron, imbecile, idiot, insane, as of the normal
individual; of social groups as of isolated selves. It is to
McDougall we owe a most effective sketch--in his introduction
to Social Psychology of the primary human emotions in their
relations to instinctive modes of behavior.

Hall, McDougall and such sociologists--lamentably few, I
fear--as Graham Wallas would agree that for the attainment of
peace we must depend upon some primary human instinct. I
venture the prediction that no one of them would select fear as
the safe basis. Instead, they surely would unite upon sympathy.

Among animals preparedness for struggles is a conspicuous cause
of strife. The monkey who stalks about among his fellows with
muscles tense, tail erect, teeth bared, bespeaking expectancy
of and longing for a fight, usually provokes it. We may not
safely argue that lower animals prove the value of preparedness
for war as a preventive measure! Among them, as among human
groups, the only justification of militarism is protection and
aggression. Preparedness for strife is provocative rather than
preventive thereof.

As individual differences, and resulting struggles, are due to
ignorance, misunderstanding, lack of the basis for intelligent
appreciation of ideals, motives and sympathy, so among nations
knowledge of bodily and mental traits, of aims, aspirations,
and national ideals fosters the feeling of kinship and favors
the instinctive attitude of sympathetic cooperation.

Every student of living things knows that to understand the
structure, habits, instincts, of any creature is to feel for
and with it. Even the lowliest type of organism acquires
dignity and worth when one becomes familiar with its life.
Children in their ignorance and lack of understanding are
incredibly cruel. So, likewise, are nations. The treatment of
inferior by superior races throughout the ages has been
childishly cruel, unjust, stupid, inimical to the best
interests not only of the victims, but also of mankind. This
has been so, not so much by reason of bad intentions, although
selfishness has been at the root of immeasurable injustice, but
primarily because of the utter lack of understanding and
sympathy. To see a savage is to despise or fear him, to know
him intimately is to love him. The same law holds of social
groups, be they families, tribes, nations or races. They can
cooperate on terms of friendly helpfulness just in the measure
in which they know one another's physical, mental and social
traits and appreciate their values, for in precisely this
measure are they capable of understanding and sympathizing with
one another's ideals.

Selfishness, the essential condition of individualism and
nationalism, must be supplanted by the sympathy of an all
inclusive social consciousness and conscience if lasting peace
is to be attained.

To further the end of this transformation of man we should
become familiar with the inborn springs to action, those
fundamental tendencies which we call instincts, for we live
more largely than is generally supposed by instinct and less by
reason. All of the organic cravings, hungers, needs, should be
thoroughly understood so that they may be effectively used.
And, finally, the laws of intellect must be at our command if
we are to meet the endlessly varying and puzzling situations of
life profitably and with the measure of adequacy our reason
would seem to justify.

Clearly, then, the least, and the most, we can do in the
interest of peace is to provide for the study of life, but
especially for the shamefully neglected or imperfectly
described phenomena of behavior and mind, in the measure which
our national wealth, our intelligence and our technical skill
make possible. For one thing, it is open to us to establish
institutes for the thorough study of every aspect of behavior
and mind in relation to structure and environment, comparable
with such institutions for social progress as the Rockefeller
Institute for Medical Research. The primary function of such
centers for the solution of vital problems should be the
comparative study, from the genetic, developmental, historical,
point of view of every aspect of the functional life of living
things, to the end that human life may be better understood and
more successfully controlled. Facts of heredity, of behavior,
of mind, of social relations, should alike be gathered and
related, and thus by the observation of the most varied types,
developmental stages, and conditions of living creatures there
should be developed a science of behavior and consciousness
which should ultimately constitute a safe basis for the social
sciences, for all forms of social endeavor, and for universal
and permanent peace.

I submit that such centers of research as the psycho-biological
institute I have so imperfectly described are sorely needed.
For it is obvious that the future of our species depends in
large measure upon how we develop the biological sciences and
what use we make of our knowledge. I further submit, and
therewith I rest my case, that familiarity with living things
breeds sympathy not contempt, and that sympathy in turn
conditions justice.

May it be granted us to work intelligently, effectively,
tirelessly for world-wide peace and service. not by the
suppression of racial and national diversities, the leveling of
the mass to a deadly sameness, but through steadily increasing
appreciation of racial and national traits. May the world, even
sooner than we dare to hope, be ruled by sympathy instead of by
fear.



THE PROGRESS OF SCIENCE

THE MISSOURI AND THE NEW YORK BOTANICAL GARDENS

THE Missouri Botanical Garden has recently celebrated the
twenty-fifth anniversary of its foundation and the New York
Botanical Garden its twentieth anniversary. Within these short
periods these gardens have taken rank among the leading
scientific institutions of the world. Botanical gardens were
among the first institutions to be established for scientific
research; indeed Parkinson, the "botanist royal" of England, on
the title page of his book of 1629, which we here reproduce,
depicts the Garden of Eden as the first botanical garden and
one which apparently engaged in scientific expeditions, for it
includes plants which must have been collected in America.
However this may be, publicly supported gardens for the
cultivation of plants of economic and esthetic value existed in
Egypt, Assyria, China and Mexico and beginning in the medieval
period had a large development in Europe there being at the
beginning of the seventeenth century botanical gardens devoted
to research in Bologna, Montpellier, Leyden, Paris, Upsala and
elsewhere. An interesting survey of the history of botanical
gardens is given in a paper by Dr. A W. Hill assistant director
of the Kew Gardens, prepared for the celebration of the
Missouri Garden, from which we have taken the illustration from
Parkinson and the pictures of Padua and Kew.

The papers presented at the celebration have been published in
a handsome volume. It includes addresses by a number of
distinguished botanists, though owing to the war several of the
foreign botanists were unable to be present. Dr. George T.
Moore, director of the garden, made in his address of welcome a
brief statement in regard to its origin in the private garden
and by the later endowment of Mr. Henry Shaw. Mr. Shaw came to
this country from England in 1818, and with a small stock of
hardware began business in one room which also served as
bedroom and kitchen. Within twenty years he had acquired a
fortune and retired from active business to devote the
remaining forty-nine years of his life to travel and to the
management of a garden surrounding his country-home on the
outskirts of St. Louis. In 1859 he erected a small museum and
library, and in 1866 Mr. James Gurney was brought to this
country as head gardener. Mr. Shaw died in 1889, leaving his
estate largely for the establishment of the Missouri Botanical
Garden, but providing also for the Henry Shaw School of Botany
of Washington University and a park for the city. With this
liberal endowment constantly increasing as the real estate
becomes more productive, Dr. William Trelease, the first
director, and Dr. George T. Moore, the present director, have
conducted an institution not only of value to the city of St.
Louis but largely contributing to the advance of botanical
science.

The New York Botanical Garden, largely through the efforts of
Dr. N. L. Britton, the present director was authorized by the
New York legislature in 1891. The act of incorporation provided
that when the corporation created should have secured by
subscription a sum not less than $250,000 the city was
authorized to set aside for the garden as much as 250 acres
from one of the public parks and to expend one half million
dollars for the construction and equipment of the necessary
buildings. The conditions were met in 1895, and the institution
has since grown in its land, and its buildings, in its
collections and in its herbaria, so that, in association with
the department of botany of Columbia University, it now rivals
in its material equipment and in the research work accomplished
any botanical institution in the world.



THE SECOND PAN-AMERICAN SCIENTIFIC CONGRESS

THERE will be held at Washington from Monday, December 27, to
Saturday, January 9, the second Pan-American Scientific
Congress, authorized by the first congress held in Santiago,
Chili, six years previously. This was one of the series of
congresses previously conducted by the republics of Latin
America. The Washington congress, which is under the auspices
of the government of the United States, with Mr. William
Phillips, third assistant secretary of state, as chairman of
the executive committee, will meet in nine sections, which,
with the chairmen, are as follows:

I. Anthropology, Wm. H. Holmes.

II. Astronomy, Meteorology, and Seismology, Robert S. Woodward.

III. Conservation of Natural Resources, Agriculture, Irrigation
and Forestry, George M. Rommel.

IV. Education, P. P. Claxton.

V. Engineering, W. H. Bixby.

VI. International Law, Public Law, and Jurisprudence, James
Brown Scott.

VII. Mining and Metallurgy, Economic Geology, and Applied
Chemistry, Hennen Jennings.

VIII. Public Health and Medical Science, Wm. C. Gorgas.

IX. Transportation, Commerce, Finance, and Taxation, L. S.
Rowe.

Each section is divided further into subsections, of which
there are forty-five, each with a special committee and
program. Several of the leading national associations of the
United States, concerned with the investigation of subjects of
pertinent interest to some of the sections of the congress,
have received and accepted invitations from the executive
committee of congress to meet in Washington at the same time
and hold one or more joint sessions with a section or
subsection of corresponding interest. Thus the nineteenth
International Congress of Americanists will meet in Washington
during the same week with the Pan-American Scientific Congress,
and joint conferences will be held for the discussion of
subjects of common interest to members of the two organizations

As an example of the wide scope of the congress we may quote
the ten subsections into which the section of education is
divided. Each of these subsections is under a committee of men
distinguished in educational work and men of eminence have been
invited to take part in the proceedings. The subjects proposed
for discussion by each of these sections are:

Elementary Education: To what extent should elementary
education be supported by local taxation, and to what extent by
state taxation? What should be the determining factors in the
distribution of support? Secondary Education: What should be
the primary and what the secondary purpose of high school
education? To what extent should courses of study in the high
school be determined by the requirements for admission to
college, and to what extent by the demands of industrial and
civic life? University Education: Should universities and
colleges supported by public funds be controlled by independent
and autonomous powers, or should they be controlled directly by
central state authority? Education of Women: To what extent is
coeducation desirable in elementary schools, high schools,
colleges and universities? Exchange of Professors and Students
between Countries: To what extent is an exchange of students
and professors between American republics desirable? What is
the most effective basis for a system of exchange? What plans
should be adopted in order to secure mutual recognition of
technical and professional degrees by American Republics?
Engineering Education: To what extent may college courses in
engineering be profitably supplemented by practical work in the
shop? To what extent may laboratory work in engineering be
replaced through cooperation with industrial plants? Medical
Education: What preparation should be required for admission to
medical schools? What should he the minimum requirements for
graduation? What portion of the faculty of a medical school
should be required to give all their time to teaching and
investigation? What instruction may best be given by physicians
engaged in medical practice? Agricultural Education: What
preparation should be required for admission to state and
national colleges of agriculture? To what extent should the
courses of study in the agricultural college be theoretical and
general, and to what extent practical and specific? To what
extent should the curriculum of any such college be determined
by local conditions? Industrial Education: What should be the
place of industrial education in the school system of the
American republics? Should it be supported by public taxation?
Should it be considered as a function of the public school
system? Should it be given in a separate system under separate
control? How and to what extent may industrial schools
cooperate with employers of labor, Commercial Education: How
can a nation prepare in the most effective manner its young men
for a business career that is to be pursued at home or in a
foreign country.

THE SCIENTIFIC MONTHLY

DECEMBER, 1915

THE INSIDE HISTORY OF A GREAT MEDICAL DISCOVERY

BY ARISTIDES AGRAMONTE, M.D., Sc.D. (HON.)

UNIVERSITY OF HAVANA.

THE construction of the Panama Canal was made possible because
it was shown that yellow fever, like malaria, could be spread
only by the bites of infected mosquitoes.

The same discovery, which has been repeatedly referred to as
the greatest medical achievement of the twentieth century, was
the means of stamping out the dreaded scourge in Cuba, as well
as in New Orleans, Rio de Janeiro, Vera Cruz, Colon, Panama and
other Cities in America.

This article is intended to narrate the motives that led up to
the investigation and also the manner in which the work was
planned, executed and terminated. No names are withheld and the
date of every important event is given, so that an interested
reader may be enabled to follow closely upon the order of
things as they occurred and thus form a correct idea of the
importance of the undertaking, the risk entailed in its
accomplishment and how evenly divided was the work among those
who, in the faithful performance of their military duties,
contributed so much for the benefit of mankind; the magnitude
of their achievement is of such proportions, that it loses
nothing of its greatness when we tear away the halo of apparent
heroism that well-meaning but ignorant historians have thrown
about some of the investigators.

The whole series of events, tragic, pathetic, comical and
otherwise, took place upon a stage made particularly fit by
nature and the surrounding circumstances.

Columbia Barracks, a military reservation, garrisoned by some
fourteen hundred troops, distant about eight miles from the
city of Havana, the latter, suffering at the time from an
epidemic of yellow fever, which the application of all sanitary
measures had failed to check or ameliorate and finally, our
experimental camp (Camp Lazear), a few army tents, securely
hidden from the road leading to Marianao, and safeguarded
against intercourse with the outside world; the whole setting
portentously silent and gloriously bright in the glow of
tropical sunlight and the green of luxuriant vegetation.

Two members of a detachment of four medical officers of the
United States Army, on the morning of August 31, 1900, were
busily examining under microscopes several glass slides
containing blood from a fellow officer who, since the day
before, had shown symptoms of yellow fever; these men were Drs.
Jesse W. Lazear and myself; our sick colleague was Dr. James
Carroll, who presumably had been infected by one of our
"experiment mosquitoes."

It is very difficult to describe the feelings which assailed us
at that moment; a sense of exultation at our apparent success
no doubt animated us; regret, because the results had evidently
brought a dangerous illness upon our coworker and with it all
associated a thrill of uncertainty for the reason of the yet
insufficient testimony tending to prove the far-reaching truth
which we then hardly dared to realize.

As the idea that Carroll's fever must have been caused by the
mosquito that was applied to him four days before became fixed
upon our minds, we decided to test it upon the first non-immune
person who should offer himself to be bitten; this was of
common occurrence and taken much as a joke among the soldiers
about the military hospital. Barely fifteen minutes may have
elapsed since we had come to this decision when, as Lazear
stood at the door of the laboratory trying to "coax" a mosquito
to pass from one test-tube into another, a soldier came walking
by towards the hospital buildings; he saluted, as it is
customary in the army upon meeting an officer, but, as Lazear
had both hands engaged, he answered with a rather pleasant
"Good morning." The man stopped upon coming abreast, curious no
doubt to see the performance with the tubes, and after gazing
for a minute or two at the insects he said: "You still fooling
with mosquitoes, Doctor?" "Yes," returned Lazear, "will you
take a bite?" "Sure I ain't scared of 'em," responded the man.
When I heard this, I left the microscope and stepped to the
door, where the short conversation had taken place; Lazear
looked at me as though in consultation; I nodded assent, then
turned to the soldier and asked him to come inside and bare his
forearm. Upon a slip of paper I wrote his name while several
mosquitoes took their fill; William E. Dean, American by birth,
belonging to Troop B, Seventh Cavalry; he said that he had
never been in the tropics before and had not left the military
reservation for nearly two months. The conditions for a test
case were quite ideal.

I must say we were in great trepidation at the time; and well
might we have been, for Dean's was the first indubitable case
of yellow fever about to be produced experimentally by the bite
of purposely infected mosquitoes. Five days afterwards, when he
came down with yellow fever and the diagnosis of his case was
corroborated by Dr. Roger P. Ames, U. S. Army, then on duty at
the hospital, we sent a cablegram to Major Walter Reed,
chairman of the board, who a month before had been called to
Washington upon another duty, apprising him of the fact that
the theory of the transmission of yellow fever by mosquitoes,
which at first was doubted so much and the transcendental
importance of which we could then barely appreciate, had indeed
been confirmed.

STATE OF THINGS BEFORE THE DISCOVERY OF MOSQUITO TRANSMISSION

Other infectious diseases, tuberculosis, for instance, may
cause a greater death-rate and bring about more misery and
distress, even to-day, than yellow fever has produced at any
one time; but no disease, except possibly cholera or the
plague, is so tragic in its development, so appalling in its
action, so devastating in its results, nor does any other make
greater havoc than yellow fever when it invades non-immune or
susceptible communities.

For two centuries, at least, the disease has been known to
exist endemically, that is, more or less continuously, in most
of the Mexican Gulf ports, extending its ravages along the West
India Islands and the cities of the Central and the South
American coast.

In the United States it has made its appearance in epidemic
form as far north as Portsmouth, N. H. At Philadelphia in 1793,
more than ten per cent. of the entire population died of yellow
fever. Other cities, like Charleston, S. C., suffered more than
twenty epidemics in as many summers, during the eighteenth
century. In the city of New Orleans, the epidemic which
developed in the summer of 1853 caused more than 7,000 deaths.
Later, in 1878, yellow fever invaded 132 towns in the United
States, producing a loss of 15,932 lives out of a total number
of cases which reached to more than 74,000: New Orleans alone
suffered a mortality of 4,600 at that time. Recently (1905),
this city withstood what is to be hoped shall prove its last
invasion, which, thanks to the modern methods employed in its
suppression, based upon the new mosquito doctrine, only
destroyed about 3,000 lives.

It is by contemplating this awful record, and much more there
is which for the sake of brevity I leave unstated, that one
realizes the boon to mankind which the successful researches of
the Army Board have proved. The work of prevention, the only
one that may be considered effective when dealing with the
epidemic diseases, was entirely misguided with regard to yellow
fever until 1901: the sick were surrounded by precautions which
were believed most useful in other infectious diseases, the
attendants were often looked upon as pestilential, and so
treated, in spite of the fact that evidence from the early
history of the disease clearly pointed to the apparent
harmlessness even of the patients themselves. All this
notwithstanding, cases continued to develop, in the face of
shotgun quarantine even, until the last non-immune inhabitant
of the locality had been either cured or buried.

The mystery which accompanied the usual course of an epidemic,
the poison creeping from house to house, along one side of a
street, seldom, crossing the road, spreading sometimes around
the whole block of houses before appearing in another
neighborhood, unless distinctly carried there by a visitor to
the infected zone who himself became stricken, all this series
of peculiar circumstances was a never-ending source of
discussion and investigation.

In the year 1900, Surgeon H. R. Carter, of the then Marine
Hospital Service, published a very interesting paper calling
attention to the interval of time which regularly occurred
between the first case of yellow fever in a given community and
those that subsequently followed; this was never less than two
weeks, a period of incubation extending beyond that usually
accorded to other acute infectious diseases. The accuracy of
these observations has later been confirmed by the mosquito
experiments hereinafter outlined.

FACTORS WHICH LED TO THE APPOINTMENT OF THE BOARD

One may well believe that such a scourge as yellow fever could
not have been long neglected by medical investigators, and so
we find that from the earliest days, when the germ-theory of
disease took its proper place in modern science, a search for
the causative agent of this infection was more or less actively
instituted.

Men of the highest attainments in bacteriology engaged in
numerous attempts to isolate the yellow fever microbe:
unfortunately not a few charlatans took advantage of the dread
and terror which the disease inspires, to proclaim their
discoveries and their specific CURES; one of these obtained
wealth and honor in one of the South American republics for
presumably having discovered the "germ" and prepared a
so-called vaccination which was expected to eradicate the
disease from that country, but for many years after the foreign
population continued to suffer as before and the intensity and
the spread of yellow fever remained unabated, although
thousands of "preventive inoculations" were made every month.

Geo. M. Sternberg in 1880, then an army surgeon, was directly
instrumental in exposing the swindle that was being
perpetrated, putting an end, after the most painstaking
investigation, to all the claims to discovery of the "germ" of
yellow fever that had been made by several medical men in
Spanish America. The experience which he obtained during a
scientific excursion through Mexico, Cuba and South America
gave him a wonderful insight as to the difficulties one has to
contend with in such work and made him realize the importance
of special laboratory training for such undertaking. It is
interesting to note that, as surgeon general of the U. S. Army,
twenty years after, General Sternberg chose and appointed the
men who constituted the yellow fever board, in Cuba.

The year before the Spanish-American war, an Italian savant,
who had obtained a well-deserved reputation as bacteriologist
while working in the Institute Pasteur of Paris, came out with
the announcement from Montevideo, Uruguay, that he had actually
discovered the much-sought-for cause of yellow fever; his
descriptions of the methods employed, though not materially
different from those followed by Sternberg many years before,
bore the imprint of truth and his experimental inoculations had
apparently been successful. Sanarelli--that is his name--for
about two years was the "hero of the hour," yet his claims have
been proved absolutely false.

The question of the identity of his "germ" was first taken up
by the writer under instructions from General Sternberg: during
the Santiago campaign I had opportunity to autopsy a
considerable number of yellow fever cases and, following
closely upon Sanarelli's directions, only three times out of
ten could his bacillus be demonstrated; at almost the same
time, Drs. Reed and Carroll, in Washington, were carrying out
experiments which showed that Sanarelli's bacillus belonged to
the hog-cholera group of bacteria and thus when found in yellow
fever cadavers could play there only a secondary role as far as
the infection is concerned.

Unfortunately, two investigators belonging to the U. S. Marine
Hospital Service, Drs. Wasdin and Gleddings, were, according to
their claims, corroborating Sanarelli's findings: there was
nothing to do but that the investigation should continue, and
so I was sent by General Sternberg to Havana in December, 1898,
with instructions and power to do all that might be necessary
to clear up the matter. Wasdin and Geddings had preceded me;
the work carried us through the summer of 1899; we frequently
investigated the same cases; I often autopsied bodies from
which we took the same specimens and made the same cultures, in
generally the same kind of media, and finally we rendered our
reports to our respective departments, Wasdin and Geddings
affirming that Sanarelli's bacillus was present in almost all
the cases, while I denied that it had such specific character
and showed its occurrence in cases not yellow fever. A virulent
epidemic which raged in the city of Santiago and vicinity
during 1899 afforded me abundant material for research.

In the meantime the city of Havana was being rendered sanitary
in a way which experience had taught would have overcome any
bacterial infection, and, in fact, the diseases of filth, such
as dysentery, tuberculosis, children's complaints and others,
decreased in a surprising manner, while yellow fever seemed to
have been little affected if at all.

Evidently, a more thorough overhauling of the matter was
necessary to arrive at the truth, and while the question of
Sanarelli and his claims was practically put aside,
Surgeon-General Sternberg, recognizing the importance of the
work before us and that its proportions were such as to render
the outcome more satisfactory by the cooperation of several
investigators in the same direction, wisely decided to create a
board for the purpose and so caused the following to be issued:

 Special Orders  No. 122
HEADQUARTERS OF THE ARMY,
ADJUTANT GENERAL'S OFFICE,
   WASHINGTON, May 24, 1900

                              Extract

34. By direction of the Secretary of War, a board of medical
officers is appointed to meet at Camp Columbia, Quemados, Cuba,
for the purpose of pursuing scientific investigations with
reference to the infectious diseases prevalent on the Island of
Cuba. Detail for the board:

Major Walter Reed, surgeon, U. S. Army;
Acting Assistant Surgeon James Carroll, U. S. Army;
Acting Assistant Surgeon Aristides Agramonte, U. S. Army;
Acting Assistant Surgeon Jesse W. Lazear, U. S. Army.

The board will act under general instructions to be
communicated to Major Reed by the Surgeon General of the Army.
                   By command of MAJOR GENERAL MILES,
                                   H. C. CORBIN,
                                      Adjutant General

It may be of interest to the reader to learn who these men were
and the reasons why they were probably selected for the work.

Major Reed, the first member in the order of appointment, was
the ranking officer and therefore the chairman of the board. He
was a regular army officer, at the time curator of the Army
Medical Museum in Washington and a bacteriologist of some
repute. He deservedly enjoyed the full confidence of the
surgeon general, besides his personal friendship and regard.
Reed was a man of charming personality, honest and above board.
Every one who knew him loved him and confided in him. A
polished gentleman and a scientist of the highest order, he was
peculiarly fitted for the work before him.

Dr. James Carroll, the second member of the board, was a
self-made man, having risen from the ranks through his own
efforts: while a member of the Army Hospital Corps he studied
medicine and subsequently took several courses at Johns Hopkins
University in the laboratory branches. At the time of his
appointment to the board he had been for several years an able
assistant to Major Reed. Personally, Carroll was industrious
and of a retiring disposition.

Dr. Jesse W. Lazear was the fourth member of the board. He had
graduated from the College of Physicians and Surgeons (Columbia
University) in the same class as the writer, in 1892, and had
afterwards studied abroad and at Johns Hopkins. Lazear had
received special training in the investigation of mosquitoes
with reference to malaria and other diseases. Stationed at
Columbia Barracks, he had been in Cuba several months before
the board was convened, in charge of the hospital laboratory at
the camp. A thorough university man, he was the type of the old
southern gentleman, kind, affectionate, dignified, with a high
sense of honor, a staunch friend and a faithful soldier.

The writer was the third member of the Army Board. Born in Cuba
during the ten years' war, while still a child, my father
having been killed in battle against the Spanish, I was taken
to the United States and educated in the public schools and in
the College of the City of New York, graduating from the
College of Physicians and Surgeons in 1892. At the breaking out
of the war I was assistant bacteriologist in the New York
Health Department. The subject of yellow fever research was my
chief object from the outset, and, at the time the board was
appointed, I was in charge of the laboratory of the Division of
Cuba, in Havana.

It may be readily seen from the brief sketch regarding the
several members that the components of the yellow-fever board
really constituted a perfectly consistent body, for the reason,
mainly, that they were all men trained in the special field
wherein their labors were to be so fruitful and that before
their appointment to the board they had been more or less
associated in scientific work.

FIRST PART OF THE WORK OF THE BOARD

My first knowledge of the existence of the board was had
through the following letter from my friend Major Reed:

                                     WAR DEPARTMENT,
                           SURGEON GENERAL'S OFFICE,
                            WASHINGTON, May 25, 1900

DR. A. AGRAMONTE,
Act'g Asst. Surgeon U. S. A.,
Military Hospital No. 1,
Havana, Cuba

My dear Doctor: An order issued yesterday from the War
Department calls for a board of medical officers for the
investigation of acute infectious diseases occurring on the
Island of Cuba. The board consists of Carroll, yourself, Lazear
and the writer. It will be our duty, under verbal instructions
from the Surgeon General, to continue the investigation of the
causation of yellow fever. The Surgeon General expects us to
make use of your laboratory at Military Hospital No. 1 and
Lazear's laboratory at Camp Columbia.

According to the present plan, Carroll and I will be quartered
at Camp Columbia. We propose to bring with us our microscopes
and such other apparatus as may be necessary for the
bacteriological and pathological work. If, therefore, you will
promptly send me a list of the apparatus on hand in your
laboratory, it will serve as a very great help in enabling us
to decide as to what we should include in our equipment. Any
suggestions that you may have to make will be much appreciated.

Carroll and I expect to leave New York, on transport, between
the 15th and 20th of June and are looking forward, with much
pleasure, to our association with you and Lazear in this
interesting work. As far as I can see we have a year or two of
work before us.

Trusting you will let me hear from you promptly, and with best
wishes,
                   Sincerely yours,
                        (Signed)
                    WALTER REED

On the afternoon of June 25, 1900, the four officers met for
the first time in their new capacity, on the veranda of the
officers' quarters at Columbia Barracks Hospital. We were fully
appreciative of the trust and aware of the responsibility
placed upon us and with a feeling akin to reverence heard the
instructions which Major Reed had brought from the surgeon
general; they comprised the investigation also of malaria,
leprosy and unclassified febrile conditions, and were given
with such detail and precision as only a man of General
Sternberg's experience and knowledge in such matters could have
prepared. After deciding upon the first steps to be taken, it
was unanimously agreed that whatever the result of our
investigation should turn out to be, it was to be considered as
the work of the board as a body, and never as the outcome of
any individual effort; that each one of us was to work in
harmony with a general plan, though at liberty to carry out his
individual methods of research. We were to meet whenever
necessary, Drs. Reed, Carroll and Lazear to remain at the
Barracks Hospital and I to stay in charge of the laboratory in
Havana, at the Military Hospital, where I also had a ward into
which yellow-fever cases from the city were often admitted.

Work was begun at once. Fortunately for our purpose, an
epidemic of yellow fever existed in the town of Quemados, in
close proximity to the military reservation of Camp Columbia.
Even before the arrival of Reed and Carroll, Lazear and I had
been studying its spread, following the cases very closely;
subsequently a few autopsies were made by me, Carroll making
cultures from the various tissues and Lazear securing fragments
for microscopical examination; a careful record was kept and
the results noted; cases gradually became less in number as the
epidemic slowly died out, about the middle of August.

In the meantime a rather severe outbreak of yellow fever had
occurred in Santa Clara, a city in the interior of the island,
having invaded the garrison and caused the death of several
soldiers; as the origin of the infection was shrouded in
mystery, and cases continued to appear among the troops even
after they had moved out of the town, it was agreed that I
should endeavor to trace the source of the epidemic and aid the
medical authorities in establishing whatever preventive
measures might seem proper. This service is here recorded
because in the general discussion of the start and course of
the epidemic with Dr. J. Hamilton Stone, the officer in charge
of the military hospital, we incidentally spoke of the possible
agency of insects in spreading the disease, pointing
particularly in this direction the fact of the infection of a
trooper who, suffering from another complaint, occupied a bed
in a ward across the yard from where a yellow fever case had
developed two weeks before.

The infection of the city of Santa Clara had evidently taken
place from Havana, distant only one night's journey by train.
Captain Stone, a particularly able officer, had already
instituted effective quarantine measures before my arrival, so
that I only remained there a few days.

But as to the actual cause of the disease we were still
entirely at sea; it helped us little to know that a man could
be infected in Havana, take the train for a town in the
interior and start an outbreak there in the course of time.

Upon rejoining my colleagues (July 2) we resumed our routine
investigations; not only in Quemados, where the disease was
being stamped out, but also in Havana, at "Las Animas" Hospital
and at Military Hospital No. 1, where my laboratory (the
division laboratory) was located. There was no scarcity of
material and the two members who until then had never seen a
case of yellow fever (Reed and Carroll) had ample opportunity,
and took advantage of it, to become acquainted with the many
details of its clinical picture which escape the ordinary
practitioner, the knowledge and the appreciation of which, in
their relative value, give the right to the title of "expert."

Since the later part of June, reports had been coming to
headquarters of an extraordinary increase of sickness among the
soldiers stationed at Pinar del Rio, the capital of the extreme
western province, and very soon the great mortality from
so-called "pernicious malarial fever" attracted the attention
of the chief surgeon, Captain A. N. Stark, who, after
consulting with Major Reed, ordered me to go there and
investigate. A man had died, supposedly from malaria, just
before my arrival on the afternoon of July 19. The autopsy
which I performed at once showed me that yellow fever had been
the cause of his death, and a search through the military
hospital wards revealed the existence of several unrecognized
cases being treated as malaria; a consultation held with the
medical officer in charge showed me his absolute incapacity, as
he was under the influence of opium most of the time (he
committed suicide several months afterwards), and so I
telegraphed the condition of things to headquarters; in answer
I received the following:

                                CHIEF SURGEON'S OFFICE,
                 HDQRS. DEPT. HAVANA AND PINAR DEL RIO,
                            QUEMADOS, CUBA, July 20, 1900

SURGEON AGRAMONTE,
Pinar del Rio Barracks,
Pinar del Rio, Cuba

Report received last night. My thanks are due for your prompt
action and confirmation of my suspicions.
                       STARK,
                       Chief Surgeon

Conditions in the hospital were such as to demand immediate
action; the commander of the post refused to believe he had
yellow fever among his 900 men and was loath to abandon his
comfortable quarters for the tent life in the woods that I
earnestly recommended. In answer to my telegram asking for
official support, I received the following:

                           CHIEF SURGEON'S OFFICE,
              HDQRS. DEPT. HAVANA AND PINAR DEL RIO,
                   QUEMADOS, CUBA, July 21, 1900

SURGEON AGRAMONTE,
Pillar del Rio Barracks,
Pinar del Rio, Cuba

Take charge of cases. Reed goes on morning train. Wire for
anything wanted. Nurses will be sent. Instructions wired
commanding officer. Other doctors should not attend cases.
Establish strict quarantine at hospital. You will be relieved
as soon as an immune can be sent to replace you. Report daily
by wire.                                       STARK,
                                          Chief Surgeon

When Major Reed came to Pinar del Rio (July 21) I had, the day
before, established a separate yellow-fever hospital, under
tents, attended by some of the men who had already passed an
attack and were thus immune. The Major and I went over the
ground very carefully, we studied the sick report for two
months back, fruitlessly trying to place the blame upon the
first case. I well remember how, as we stood in the men's
sleeping quarters, surrounded by a hundred beds, from several
of which fatal cases had been removed, we were struck by the
fact that the later occupants had not developed the disease. In
connection with this, and particularly interesting, was the
case of a soldier prisoner who had been confined to the
guard-house since June 6; he showed the first symptoms of
yellow fever on the twelfth and died on the eighteenth; none of
the other eight prisoners in the same cell caught the
infection, though one of them continued to sleep in the same
bunk previously occupied by his dead comrade. More than this;
the three men who handled the clothing and washed the linen of
those who had died during the last month were still in perfect
health. Here we seemed to be in the presence of the same
phenomenon remarked by Captain Stone in reference to his case
at Santa Clara, and before that by several investigators of
yellow fever epidemics; the infection at a distance, the
harmless condition of bedding and clothing of the sick; the
possibility that some insect might be concerned in spreading
the disease deeply impressed us and Major Reed mentions the
circumstance in his later writings. This was really the first
time that the mosquito transmission theory was seriously
considered by members of the board, and it was decided that,
although discredited by the repeated failure of its most ardent
supporter, Dr. Carlos J. Finlay, of Havana, to demonstrate it,
the matter should be taken up by the board and thoroughly
sifted.

The removal of the troops out of Pinar del Rio was the means of
at once checking the propagation of the disease.

On the first day of August the board met and after due
deliberation determined to investigate mosquitoes in connection
with the spread of yellow fever. As Dr. Lazear was the only one
of us who had had any experience in mosquito work, Major Reed
thought proper that he should take charge of this part of the
investigation in the beginning, while we, Carroll and I,
continued with the other work on hand, at the same time
gradually becoming familiar with the manipulations necessary in
dealing with the insects.

A visit was now made to Dr. Finlay, who, much elated at the
news that the board was about to investigate his pet theory,
the transmission of yellow fever from man to man by mosquitoes,
very kindly explained to us many points regarding the life of
the one kind he thought most guilty and ended by furnishing us
with a number of eggs which, laid by a female mosquito nearly a
month before, had remained unhatched on the inside of a half
empty bowl of water in his library.

Much to our disappointment and regret, during the first week of
August, Major Reed was recalled to Washington that he might, in
collaboration with Drs. Vaughan and Shakespeare, complete the
report upon "Typhoid Fever in the Army." Thus we were deprived
of his able counsel during the first part of the mosquito
research. Major Reed was detained longer than he expected and
could not return to Cuba until early in October, several days
after Lazear's death.

The mosquito eggs obtained from Dr. Finlay hatched out in due
time; the insects sent to Washington for their exact
classification were declared by Dr. L. O. Howard, entomologist
to the Agricultural Department, to be Culex fasciatus. Later,
they have been called Stegomyia fasciatus and now go under the
name of Stegomyia calopus (Aedes cal.).

Lazear applied some of these mosquitoes to cases of yellow
fever at "Las Animas" Hospital, keeping them in separate glass
tubes properly labeled, and every thing connected with their
bitings was carefully recorded; the original batch soon died
and the work was carried on with subsequent generations from
the same.

The lack of material at Quemados caused us to remove our field
of action to Havana, where cases of yellow fever continued to
appear. We met almost every day at "Las Animas" Hospital, where
Lazear was trying to infect his mosquitoes, or now and then I
performed autopsy upon a case, and Carroll secured sufficient
cultures to last him for several days of bacteriological
investigation.

Considering that, in case our surmise as to the insect's action
should prove to be correct, it was dangerous to introduce
infected mosquitoes amongst a population of 1,400 non-immunes
at Camp Columbia, Dr. Lazear thought best to keep his
presumably infected insects in my laboratory at the Military
Hospital No. 1, from where he carried them back and forth to
the patients who were periodically bitten.

Incidentally, after the mosquitoes fed upon the yellow fever
patients, they were applied, at intervals of two or three days,
to whoever would consent to run the risk of contracting yellow
fever in this way; needless to say, current opinion was against
this probability and as time passed and numerous individuals
who had been bitten by insects which had previously fed upon
yellow fever blood remained unaffected, I must confess that
even the members of the board, who were rather sanguine in
their expectations, became somewhat discouraged and their faith
in success very much shaken.

No secret was made of our attempts to infect mosquitoes; in
fact many local physicians became intensely interested, and
Lazear and his tubes were the subject of much comment on the
part of the Havana doctors, who nearly twenty years before had
watched and laughed at Dr. Finlay, then bent apparently upon
the same quest in which we were now engaged. Dr. Finlay himself
was somewhat chagrined when he learned of our failure to infect
any one with mosquitoes, but, like a true believer, was
inclined to attribute this negative result more to some defect
in our technique than to any flaw in his favorite theory.

Although the board had thought proper to run the same risks, if
any, as those who willingly and knowingly subjected themselves
to the bites of the supposedly infected insects, opportunity
did not offer itself readily, since Major Reed was away in
Washington and Carroll, at Camp Columbia, engrossed in his
bacteriological investigations came to Havana only when an
autopsy was on hand or a particularly interesting case came up
for study. I was considered an immune, a fact that I would not
like to have tested, for though born in the island of Cuba, I
had practically lived all my life away from a yellow fever
zone; it was therefore presumed that I ran no risk in allowing
mosquitoes to bite me, as I frequently did, just to feed them
blood, whether they had previously sucked from yellow fever
cases or not. And so, time passed and several Americans and
Spaniards had subjected themselves in a sporting mood to be
bitten by the infected (?) mosquitoes without causing any
untoward results, when Lazear applied to himself (August 16,
1900) a mosquito which ten days before had fed upon a mild case
of yellow fever in the fifth day of his disease; the fact that
no infection resulted, for Lazear continued in excellent health
for a space of time far beyond the usual period of incubation,
served to discredit the mosquito theory in the opinion of the
investigators to a degree almost beyond redemption, and the
most enthusiastic, Dr. Lazear himself, was almost ready to
"throw up the sponge."

I had as laboratory attendant a young American, a private
belonging to the Hospital Corps of the Army, who more than once
had bared his arm to allow a weak mosquito a fair meal with
which to regain its apparently waning strength; Loud, for that
was his name, derided the idea that such a little beast could
do so much harm as we seemed ready to accuse it of, although he
was familiar with the destruction caused by bacteria, but then,
he used to say, "bacterial work in armies of more than a
million bugs at the same time and no one would be d---- fool
enough to let more than one or two gnats sting him at once."

This state of things, the gradual loss of faith in the danger
which mosquitoes seemed to possess, led Dr. Lazear to relax a
little and become less scrupulous in his care of the insects,
and often, after applying them to patients, if pressed for
time, he would take them away with him to his laboratory at
Columbia Barracks, where, the season being then quite warm,
they could be kept as comfortably as at the Military Hospital
laboratory. Thus it happened that on the twenty-seventh of
August he had spent the whole morning at "Las Animas" Hospital
getting his mosquitoes to take yellow-fever blood: the
procedure was very simple; each insect was contained in a glass
tube covered by a wad of cotton, the same as is done with
bacterial cultures. As the mouth of the tube is turned
downwards, the insect usually flies towards the bottom of the
tube (upwards), then the latter is uncovered rapidly and the
open mouth placed upon the forearm or the abdomen of the
patient; after a few moments the mosquito drops upon the skin
and if hungry will immediately start operations; when full, by
gently shaking the tube, the insect is made to fly upwards
again and the cotton plug replaced without difficulty. It so
happened that this rather tedious work, on the day above
mentioned, lasted until nearly the noon hour, so that Lazear,
instead of leaving the tubes at the Military Hospital, took
them all with him to Camp Columbia: among them was one insect
that for some reason or other had failed to take blood when
offered to it at "Las Animas" Hospital.

This mosquito had been hatched in the laboratory and in due
time fed upon yellow-fever blood from a severe case on August
15, that is, twelve days before, the patient then being in the
second day of his illness; also at three other times, six days,
four days and two days before. Of course, at the time, no
particular attention had been drawn to this insect, except that
it refused to suck blood when tempted that morning.

After luncheon that day, as Carroll and Lazear were in the
laboratory attending to their respective work, the conversation
turning upon the mosquitoes and their apparent harmlessness,
Lazear remarked how one of them had failed to take blood, at
which Carroll thought that he might try to feed it, as
otherwise it was liable to die before next day (the insect
seemed weak and tired); the tube was carefully held first by
Lazear and then by Carroll himself, for a considerable length
of time, upon his forearm, before the mosquito decided to
introduce its proboscis.

This insect was again fed from a yellow fever case at "Las
Animas" Hospital on the twenty-ninth, two days later, Dr.
Carroll being present, though not feeling very well, as it was
afterwards ascertained.

We three left the yellow-fever hospital together that
afternoon; I got down from the doherty-wagon where the road
forks, going on to the Military Hospital, while Carroll and
Lazear continued on their way to Camp Columbia. On the
following day, Lazear telephoned to me in the evening, to say
that Carroll was down with a chill after a sea bath taken at
the beach, a mile and a half from Camp, and that they suspected
he had malaria; we therefore made an appointment to examine his
blood together the following morning.

When I reached Camp Columbia I found that Carroll had been
examining his own blood early that morning, not finding any
malarial parasites; he told me he thought he had "caught cold"
at the beach: his suffused face, blood-shot eyes and general
appearance, in spite of his efforts at gaiety and unconcern,
shocked me beyond words. The possibility of his having yellow
fever did not occur to him just then; when it did, two days
later, he declared he must have caught it at my autopsy room in
the Military Hospital, or at "Las Animas" Hospital, where he
had been two days before taking sick. Although we insisted that
he should go to bed in his quarters, we could only get him to
rest upon a lounge, until the afternoon, when he felt too sick
and had to take to his bed.

Lazear and I were almost panic-stricken when we realized that
Carroll had yellow fever. We searched for all possibilities
that might throw the blame for his infection upon any other
source than the mosquito which bit him four days before;
Lazear, poor fellow, in his desire to exculpate himself, as he
related to me the details of Carroll's mosquito experiment,
repeatedly mentioned the fact that he himself had been bitten
two weeks before without any effect therefrom and finally, what
seemed to relieve his mind to some extent, was the thought that
Carroll offered himself to feed the mosquito and that he held
the tube upon his own arm until the work was consummated.

I have mentioned before that, as Lazear and I, vaguely hoping
to find malarial parasites in Carroll's blood, sat looking into
our microscopes that morning, the idea that the mosquito was
what brought him down gradually took hold of our minds, but as
our colleague had been exposed to infection in other ways, by
visiting the yellow fever hospital "Las Animas," as well as the
infected city of Havana, it was necessary to subject that same
mosquito to another test and hence the inoculation of Private
Dean, which is described in the opening chapter of this
history.

TERMINATION OF THE FIRST SERIES OF MOSQUITO EXPERIMENTS.

DEATH OF LAZEAR.

The month of September, 1900, was fraught with worry and
anxiety: what with Carroll's and Private Dean's attacks of
yellow fever and Major Reed's inability to return, Lazear and I
were well-nigh on the verge of distraction. Private Dean was
not married, but Carroll's wife and children, a thousand miles
away, awaited in the greatest anguish the daily cablegram which
told them the condition of the husband and father, who was
fighting for life, sometimes the victim of the wildest delirium
caused by consuming fever, at others almost about to collapse,
until one day, the worst of the disease being over, the wires
must have thrilled at our announcement, "Carroll out of
danger."

Fortunately both he and Dean made an uninterrupted recovery,
but we were still to undergo the severest trial, a sorrow
compared to which the fearful days of Carroll's sickness lose
all importance and dwindle almost into insignificance.

On the morning of the eighteenth my friend and classmate
Lazear, whom in spite of our short intercourse I had learned to
respect and in every way appreciate most highly, complained
that he was feeling "out of sorts." He remained all day about
the officers' quarters and that night suffered a moderate
chill. I saw him the next day with all the signs of a severe
attack of yellow fever.

Carroll was already walking about, though enfeebled by his late
sickness, and we both plied Lazear with questions as to the
origin of his trouble; I believe we affectionately chided him
for not having taken better care of himself. Lazear assured us
that he had not experimented upon himself, that is, that he had
not been bitten by any of the purposely infected mosquitoes.

After the case of Dean so plainly demonstrated the certainty of
mosquito infection, we had agreed not to tempt fate by trying
any more upon ourselves, and even I determined that no mosquito
should bite me if I could prevent it, since the subject of my
immunity was one that could not be sustained on scientific
grounds; at the same time, we felt that we had been called upon
to accomplish such work as did not justify our taking risks
which then seemed really unnecessary. This we impressed upon
Major Reed when he joined us in October and for this reason he
was never bitten by infected mosquitoes.

Lazear told us, however, that while at "Las Animas" Hospital
the previous Thursday (five days before), as he was holding a
test-tube with a mosquito upon a man's abdomen, some other
insect which was flying about the room rested upon his hand; at
first, he said, he was tempted to frighten it away, but, as it
had settled before he had time to notice it, he decided to let
it fill and then capture it; besides, he did not want to move
in fear of disturbing the insect contained in his tube, which
was feeding voraciously. Before Lazear could prevent it, the
mosquito that bit him on the hand had flown away. He told us in
his lucid moments, that, although Carroll's and Dean's cases
had convinced him of the mosquito's role in transmitting yellow
fever, the fact that no infection had resulted from his own
inoculation the month before had led him to believe himself, to
a certain extent, immune.

How can I describe the agony of suspense which racked our souls
during those six days? It seemed to us as though a life was
being offered in sacrifice for the thousands which it was to
contribute in saving. Across the span of thirteen years the
memory of the last moments comes to me most vividly and
thrilling, when the light of reason left his brain and shut out
of his mind the torturing thought of the loving wife and
daughter far away, and of the unborn child who was to find
itself fatherless on coming to the world.

Tuesday, the twenty-fifth of September saw the end of a life
full of promise; one more name, that of Jesse W. Lazear, was
graven upon the portals of immortality. And we may feel justly
proud for having had it, in any way, associated with our own.

The state of mind in which this calamity left us may better be
imagined than described. The arrival of Major Reed several days
after in a great measure came to relieve the tensity of our
nerves and render us a degree of moral support of which we were
sorely in need.

Lazear's death naturally served to dampen our fruition at the
success of the mosquito experiments, but, this notwithstanding,
when the facts were known we were the subjects of much
congratulation and the question whether the theory had been
definitely demonstrated or not was the theme of conversation
everywhere, about Havana and Camp Columbia particularly. We
fully realized that three cases, two experimental and one
accidental, were not sufficient proof, and that the medical
world was sure to look with doubt upon any opinion based on
such meager evidence; besides, in the case of Carroll, we had
been unable to exclude the possibility of other means of
infection, so that we really had but one case, Dean's, that we
could present as clearly demonstrative and beyond question. In
spite of this, we thought that the results warranted their
presentation in the shape of a "Preliminary Note," and after
all the data were carefully collected from Lazear's records and
those at the Military Hospital, a short paper was prepared
which the Major had the privilege to read at the meeting of the
American Public Health Association, held on October 24, in the
city of Indianapolis.

For this purpose Major Reed went to the States two weeks after
his return to Cuba, and Carroll also took a short leave of
absence so as to fully recuperate, in preparation for the
second series of inoculations which we had arranged to
undertake, after the Indianapolis meeting.

These inoculations, according to our program, were to be made
upon volunteers who should consent to suffer a period of
previous quarantine at some place to be selected in due time,
away from any possibility of yellow fever.

It so happened then that I was left the only member of the
board in Cuba and, under instructions from Major Reed, I began
to breed mosquitoes and infect them, as Lazear used to do,
wherever cases occurred, keeping them at my laboratory in the
Military Hospital No. 1. Major Reed had also asked me to look
about for a proper location wherein to continue the work upon
his return.

ORIGIN AND DEVELOPMENT OF THE MOSQUITO THEORY

The possible agency of insects in the propagation of yellow
fever was thought of by more than one observer, from a very
early period in the history of this disease. For instance,
Rush, of Philadelphia, in 1797, noticed the excessive abundance
of mosquitoes during that awful epidemic. Subsequently, several
others spoke of the coincidence of gnats or mosquitoes and
yellow fever, but without ascribing any direct relation to the
one regarding the other. Of course, man-to-man infection
through the sole intervention of an insect was a thing entirely
inconceivable and therefore unthought of until very recently,
and in truth the discovery, as far as yellow fever is
concerned, was the result of a slow process of evolution of the
fundamental fact, taken in connection with similar findings, in
other diseases.

The earliest direct reference is found in the writings of Dr.
Nott, of Mobile, Ala., who in 1848 suggested that the
dissemination of the yellow fever poison was evidently by means
of some insect "that remained very close to the ground." But
the first who positively pointed to the mosquito as the
spreader of yellow fever, who showed that absence of mosquitoes
precluded the existence of the disease and who prescribed the
ready means to stamp it out, by fumigation and by preventing
the bites of the insects, was Dr. Louis D. Beauperthuy, a
French physician, then located in Venezuela. The writer has an
original copy of his paper, published in 1853, where he fastens
the guilt upon the domestic mosquitoes, believing, in accord
with the prevailing teachings of medical science, that the
mosquitoes infected themselves by contact or feeding upon the
organic matter found in the stagnant waters where they are
hatched, afterwards inoculating the victims by their sting. He
recognized the fact that yellow fever is not contagious and
therefore could not think of the possibility of man-to-man
infection, as we know it to-day. The keenest observer was this
man Beauperthuy, and, even at that benighted time in the
history of tropical medicine, made most interesting studies of
the blood and tissues, employing the microscope and the
chemical reactions in his research. No one believed him, and a
commission appointed to report upon his views said that they
were inadmissible and all but declared him insane.

This field of investigation remained dormant for a
comparatively long period of time. Meanwhile another medical
writer, Dr. Greenville Dowell, mentions in 1876, that "if we
compare the effect of heat and cold on gnats and mosquitoes
with yellow fever, it will be difficult to believe it is of the
same nature, as it is controlled by the same natural laws."
Soon after this, in 1879, the first conclusive proof of the
direct transmission of a disease from man-to-man was presented
by the father of tropical medicine, Sir Patrick Manson, with
regard to filaria, a blood infection that often causes the
repulsive condition known as elephantiasis and which the
mosquito takes from man and after a short time gives over to
another subject. This discovery attracted world-wide attention
and many looked again towards the innumerable species of biting
insects that dwell in the Tropic Zone, as possible carriers of
the obscure diseases which also prevail in those regions.

In 1881, Dr. Carlos Finlay, of Havana, in an exhaustive paper
read before the Royal Academy of Sciences, gave as his opinion
that yellow fever was spread by the bites of mosquitoes
"directly contaminated by stinging a yellow fever patient (or
perhaps by contact with or feeding from his discharge)." This
latter view he held as late as 1900, which, although correct in
the main fact of the transmission of the germ from a patient to
a susceptible person by the mosquito, the modus operandi, as he
conceived it, was entirely erroneous.

Dr. Finlay, unfortunately was unable to produce experimentally
a single case of fever that could withstand the mildest
criticism, so that at the time when the Army Board came to
investigate the causes of yellow fever in Cuba, his theory,
though practically the correct one, had been so much
discredited, in a great measure by his own failures, that the
best-known experts considered it as an ingenious, but wholly
fanciful, one and many thought it a fit subject for humorous
and sarcastic repartee. Finlay also believed, erroneously, that
repeated bites of contaminated insects might protect against
yellow fever and that the mosquitoes were capable of
transmitting the germ to the next generation.

The wonderful discoveries of Theobald Smith, as to the agency
of ticks in spreading Texas fever of cattle, and those of Ross
and the Italian investigators who showed conclusively that
malaria was transmitted by a species of mosquito, brought the
knowledge of these various diseases to the point where the Army
Board took up the investigation of yellow fever.

SECOND AND FINAL SERIES OF MOSQUITO EXPERIMENTS

Major Reed came back to Havana in the early part of November,
Carroll following a week after.

During their absence, I had been applying mosquitoes to yellow
fever patients at "Las Animas" Hospital, keeping them in my
laboratory, as it was done at the beginning of the
investigation; the season being more advanced, now and then a
cold "norther" would blow and my insects suffered very much
thereby, so that I had the greatest trouble in preventing their
untimely death: to this may be added the difficulty met in
feeding them blood, for now that I knew their sting was
dangerous, unto death perhaps, I could not allow any
indiscriminate biting, but had to select for the purpose
individuals who had suffered an attack of the disease and were
therefore immune.

The necessity for an experimental camp became more imperative
as time passed, not only where proper quarantine and isolation
could be established, but also where the insects intended for
the inoculations might receive better care. This entailed
considerable expense.

Fortunately for us, the military governor of the island at that
time, Brigadier General Leonard Wood, was a man who had
received a thorough medical training; broad and clear-minded,
he fully appreciated the importance of what might be the
outcome of our researches. We found in him the moral support
which we so much needed and, further, he promptly placed at the
disposal of the board sufficient funds with which to carry on
the experiments to the end. I firmly believe that had other
been the circumstances, had a more military and less scientific
man been at the head of the government, the investigation would
have terminated there and then, and many years would have
passed, with hundreds of lives uselessly sacrificed, before we
could have attained our present remarkable sanitary triumphs.

We immediately set about choosing a location for our camp. I
had already looked over the ground, preferring the proximity of
Camp Columbia, from where supplies could be easily obtained and
because the Military Hospital there could be used for treating
the cases that we intended to produce; I was therefore
favorably impressed with the seclusion offered by a spot
situated a short distance from the main road, in a farm, named
San Jose, belonging to my friend Dr. Ignacio Rojas, of Havana.
Major Reed decided upon this place after looking at many others
in the neighborhood, so that on the twentieth of November we
inaugurated our camp, which we named Camp Lazear, in honor to
the memory of our dead colleague, consisting then of seven army
tents, guarded by a military garrison, composed of men who had
been carefully selected by virtue of their previous good record
and their interest in the work to be undertaken.

Feeling that we had proved, to ourselves at least, the agency
of the mosquito in yellow fever, it became our duty to disprove
the theory, until then held as a certainty by many authorities,
to the effect that the soiled bedding and clothing, the
secretions and excreta of patients, were infectious and in some
way carried the germ of the disease. We therefore designed a
small wooden building, to be erected a short distance from the
tense, with a capacity of 2,800 cubic feet. The walls and
ceiling were absolutely tight, the windows and vestibuled door
screened and all precautions taken to prevent the entrance of
insects.

Into this, called the "infected clothing building," three beds
and a stove, to maintain a high tropical temperature, were
introduced; also mattresses and pillows, underwear, pajamas,
towels, sheets, blankets, etc., soiled with blood and
discharges from yellow fever cases: these articles were put on
the beds, hung about the room and packed in a trunk and two
boxes placed there for the purpose.

The building was finished and equipped on November 30. That
Friday evening, Dr. Robert P. Cook, U. S. Army, with two other
American volunteers, entered it and prepared to pass the night:
they had instructions to unpack the boxes and trunk, to handle
and shake the clothing and in every way to attempt to
disseminate the yellow fever poison, in case it was contained
in the various pieces. We watched the proceedings from the
outside, through one of the windows. The foul conditions which
developed upon opening the trunk were of such a character that
the three men were seen to suddenly rush out of the building
into the fresh air; one of them was so upset that his stomach
rebelled; yet, after a few minutes, with a courage and
determination worthy only of such a cause, they went back into
the building and passed a more or less sleepless night, in the
midst of indescribable filth and overwhelming stench.

For twenty consecutive nights these men went through the same
performance; during the day they remained together, occupying a
tent near their sleeping quarters. Dr. Cook, by voluntarily
undergoing such a test, without remuneration whatsoever, proved
his faith in the mosquito theory; his demonstration of the
harmless character of so-called infected clothing, in yellow
fever, has been of the greatest importance. The other six men
(two of them with Dr. Cook) who were subjected to this test,
received each a donation of one hundred dollars for his
services.

Many days even before the establishment of the experimental
camp, the board had heard that several men who knew of our work
were willing to submit to the inoculations and thus aid in
clearing up the mystery of yellow fever. Two of these require
special mention, John R. Kissinger, a private in the Hospital
Corps of the Army, was the first to offer himself most
altruistically, for, as he expressed it, his offer was made
without any desire for pecuniary or other consideration and
solely "in the interest of humanity and the cause of science,"
the other, J. J. Moran, a civilian employee, also stipulated as
a condition that he was to receive no pay for his services.
Both these men, in due time, suffered from yellow fever and
until very recently had never obtained any reward for the great
risk which they ran so voluntarily and praiseworthily.

Kissinger, who after several years' service in the army became
disabled, is receiving a pension from the government; Moran, I
hope, is still well and in the employ of the Isthmian Canal
Commission, justly enjoying the friendship and confidence of
his superior officers. The names of Kissinger and Moran should
figure upon the roll of honor of the U. S. Army.

On the day the camp was definitely organized, Kissinger, who
had not gone outside the military reservation for more than a
month, moved into Camp Lazear and received his first bite from
a mosquito which evidently was not "loaded" for, again on
November 23, he was stung by the same insect without result. On
December 5, five mosquitoes were applied, which brought about a
moderate infection in three days. Moran was also bitten by
mosquitoes which were supposed to be infected on November 26
and 29, both times unsuccessfully. As will be seen, he was
infected later on.

By this time we had decided, the weather having cooled
considerably, that it was better to keep the mosquitoes at a
higher temperature and nearer to the men who were to be
inoculated; therefore it was planned to put up another small
wooden structure, which was to be known as the "Mosquito
Building" in which an artificial temperature could be
maintained; at my suggestion, the building was so designed that
it might serve to infect individuals; by liberating infected
mosquitoes on the inside and exposing some person to their
stings, we could try to reproduce the infection as we felt it
occurred in nature. Another reason for the mosquito house was
the need to obviate the transportation of the insects from the
Military Hospital, where I kept them, to our camp, which could
not be easily done without subjecting them to severe injury.
Upon one occasion I was taking four infected mosquitoes in the
pocket inside my blouse from the laboratory in Havana to the
experimental camp, accompanied by my attendant Private Loud;
the horse which pulled my buggy, a rather spirited animal,
becoming frightened at a steam roller, as we went around the
corner of Colon Cemetery, started to race down the hill towards
the Almendares River: Loud was thrown out by the first
cavortings of the horse, who stood on its hind legs and jumped
several times before dashing away, while I held tightly to the
tubes in my pocket, as the buggy upset and left me stranded
upon a sand pile in the middle of the road; the mosquitoes were
quite safe, however, and upon my arrival at Camp Lazear I
turned them over to Carroll for his subsequent care.

Another difficulty afterwards encountered was the scarcity of
material susceptible to infection, for, although several men
had expressed a willingness to be inoculated, when the time
came; they all preferred the "infected clothing" experiment to
the stings of our mosquitoes. We then thought best to secure
lately landed Spaniards, to whom the probable outcome of the
test might be explained and their consent obtained for a
monetary consideration. Our method was as follows; as soon as a
load of immigrants arrived, I would go to Tiscornia, the
Immigration Station across the Bay of Havana, and hire eight or
ten men, as day laborers, to work in our camp. Once brought in,
they were bountifully fed, housed under tents, slept under
mosquito-bars and their only work was to pick up loose stones
from the grounds, during eight hours of the day, with plenty of
rest between. In the meantime, as the days of observation
passed, I carefully questioned them as to their antecedents,
family history and the diseases which they might have suffered;
those who had lived in Cuba or any other tropical country
before were discarded at once and also those who were under age
or had a family dependent upon them. When the selection was
finally made, the matter of the experiment was put to them.
Naturally, they all felt more or less that they were running
the risk of getting yellow fever when they came to Cuba and so
were not at all averse to allow themselves to be bitten by
mosquitoes: they were paid one hundred dollars for this, and
another equal sum if, as a result of the biting experiment,
they developed yellow fever. Needless to say, no reference was
made to any possible funeral expenses. A written consent was
obtained from each one, so that our moral responsibility was to
a certain extent lessened. Of course, only the healthiest
specimens were experimented upon.

It so happened that some reporter discovered what we were
about, or perhaps some invidious person misrepresented the
facts; at any rate, on the twenty-first of November a Spanish
newspaper appeared with flaring headlines denouncing the
American doctors who were taking advantage of the poor
immigrants and experimenting with them by injecting all sorts
of poisons! It called upon the Spanish consul to look after his
subjects. In view of this we felt that if such campaign
continued, in a short time it would either make it impossible
to secure subjects or cause diplomatic pressure to be exerted
against the continuance of our experiments. It was thought best
to "beard the lion in his den" so the three of us called upon
the consul the following day. He was surprised to hear one of
us address him in his own language, having taken us all for
Americans on first sight, and when I explained to him our
method of procedure and showed him the signed contracts with
the men, being an intelligent man himself, he had no objections
to offer and told us to go ahead and not bother about any howl
the papers might make.

The first three cases (two of them Spaniards) which we produced
came down with yellow fever within a very short period, from
December 8 to 13; it will therefore not surprise the reader to
know that when the fourth case developed on December 15, and
was carried out of the camp to the hospital, it caused a
veritable panic among the remaining Spaniards, who, renouncing
the five hundred pesetas that each had in view, as Major Reed
very aptly put it, "lost all interest in the progress of
science and incontinentally severed their connection with Camp
Lazear."

But there was a rich source to draw from, and the unexpected
stampede only retarded our work for a short time. Our
artificial epidemic of yellow fever was temporarily suspended
while a new batch of susceptible material was brought in,
observed and selected. The next case for that reason was not
produced upon a Spaniard until December 30.

In the face of the negative experiments with supposedly
contaminated articles, it rested with us to show how a house
became infected and for this purpose the main part of the
"mosquito building" was utilized.

This chamber was divided into two compartments by a double
wire-screen partition, which effectually prevented mosquitoes
on one side from passing to the other; of course there were no
mosquitoes there to begin with, as the section of the building
used for breeding and keeping them was entirely separated from
the other, and there could be no communication between them.

On the morning of December 21, a jar containing fifteen hungry
mosquitoes, that had previously stung cases of yellow fever,
was introduced and uncovered in the larger compartment, where a
bed, with all linen perfectly sterilized, was ready for
occupancy. A few minutes after, Mr. Moran, dressed as though
about to retire for the night, entered the room and threw
himself upon the bed for half an hour; during this time two
other men and Major Reed remained in the other compartment,
separated from Moran only by the wire-screen partition. Seven
mosquitoes were soon at work upon the young man's arms and
face; he then came out, but returned in the afternoon, when
five other insects bit him in less than twenty minutes. The
next day, at the same hour of the afternoon, Moran entered the
"mosquito building" for the third time and remained on the bed
for fifteen minutes, allowing three mosquitoes to bite his
hands. The room was then securely locked, but the two Americans
continued to sleep in the other compartment for nearly three
weeks, without experiencing any ill effects.

Promptly on Christmas morning Moran, who had not been exposed
to infection except for his entrance into the "mosquito
building" as described, came down with a well-marked attack of
yellow fever.

The temperature in this room, where these mosquitoes had been
released, was kept rather high and a vessel with water was
provided, where they might lay their eggs if so inclined, but
notwithstanding all these precautions, it was subsequently
found that the insects had been attacked by ants, so that by
the end of the month only one of the fifteen mosquitoes
remained alive.

It is hardly necessary to detail here how seven other men were
subjected to the sting of our infected mosquitoes, of which
number five developed the disease, but it may be interesting to
note that two of these men had been previously exposed in the
"infected clothing building" without their becoming infected,
showing that they were susceptible to yellow fever after all.

The evidence so far seemed to show that the mosquito could only
be infected by sucking blood of a yellow-fever patient during
the first three days of the disease; to prove that the parasite
was present in the circulating blood at that time we therefore
injected some of this fluid taken from a different case each
time, under the skin of five men: four of these suffered an
attack of yellow fever as the result of the injection. The
other one, a Spaniard, could not be infected either by the
injection of blood or the application of mosquitoes which were
known to be infected, showing that he had a natural immunity
or, more likely, that he had had yellow fever at some previous
time.

While selecting the Spaniards, it was often ascertained that
they had been in Cuba before, as soldiers in the Spanish army
usually, and the natural conclusion was that they had undergone
infection; it was very seldom that any escaped during the
Spanish control of the island.

Thus terminated our experiments with mosquitoes which, though
necessarily performed on human beings, fortunately did not
cause a single death; on the other hand, they served to
revolutionize all standard methods of sanitation with regard to
yellow fever. They showed the uselessness of disinfection of
clothing and how easily an epidemic can be stamped out in a
community by simply protecting the sick from the sting of the
mosquitoes and by the extensive and wholesale destruction of
these insects which, added to the suppression of their breeding
places, if thoroughly carried out, are the only measures
necessary to forever rid a country of this scourge.

Besides keeping a sharp lookout against the importation of
yellow fever cases, these are the simple rules that have kept
the Panama Canal free and prevented the slaughter of hundreds
of foreigners, so generally expected every year, in former
times.

Since we made our demonstration in 1901, our work has been
corroborated by various commissions appointed for the purpose,
in Mexico, Brazil and Cuba, composed variously of Americans,
French, English, Cuban, Brazilian and German investigators.
Nothing has been added to our original findings; nothing has
been contradicted of what we have reported, and to-day, after
nearly thirteen years, the truths that we uncovered stand
incontrovertible; besides, they have been the means of driving
out yellow fever from Cuba, the United States (Laredo, Texas,
1903 and New Orleans, La., 1905), British Honduras and several
cities of Brazil.

Of the Army Board only I remain. Lazear, as reported, died
during the early part of our investigations; Reed left us in
1902 and Carroll only five years later. The reader may wonder
of what benefit was it to us, this painstaking and remarkable
accomplishment which has been such a blessing to humanity! See
what the late Surgeon General of the U. S. Army had to say in
his report (Senate Document No. 520, Sixty-first Congress,
second session):

1. Major Walter Reed, surgeon, United States Army, died in
Washington, D. C., from appendicitis, November 23, 1902, aged
51. His widow, Emilie Lawrence Reed, is receiving a pension of
$125 a month.

2 Maj. James Carroll was promoted from first lieutenant to
major by special act of Congress, March 9, 1907. He died in
Washington, D C., of myocarditis, September 16, 1907. His
widow, Jennie H. Carroll, since his death, has received an
annuity of $125 a month, appropriated from year to year in the
Army appropriation bill.

3. Dr. Jesse W. Lazear, contract surgeon, United States Army,
died at Camp Columbia, Cuba, of yellow fever, September 25,
1900. His widow, Mabel M. Lazear, since his death, has received
an annuity of $125 a month appropriated from year to year in
the Army appropriation bill.

4. Dr. Aristides Agramonte is the only living member of the
board. He is professor of bacteriology and experimental
pathology in the University of Habana and has never received,
either directly or indirectly, any material reward for his
share in the work of the board.

It is not for me to make any comments: the above paragraphs
have all the force of a plain, truthful statement of facts.
Perhaps it is thought that enough reward is to be found in the
contemplation of so much good derived from one's own efforts
and the feeling it may produce of innermost satisfaction and in
forming the belief that one had not lived in vain. In a very
great measure, I know, the thought is true.



THE EVOLUTION OF THE STARS AND THE FORMATION OF THE EARTH. IV

BY WILLIAM WALLACE CAMPBELL

DIRECTOR OF THE LICK OBSERVATORY, UNIVERSITY OF CALIFORNIA

THE PLANETESIMAL HYPOTHESIS

THE most elaborate structure yet proposed to explain the origin
of the solar system is the planetesimal hypothesis by
Chamberlin and Moulton. The energy which these investigators
have devoted to formulating and testing this hypothesis, in the
light of the principles of mechanics, has been commensurate
with the importance of the subject. They postulate that the
materials now composing the Sun, planets, and satellites, at
one time existed as a spiral nebula, or as a great spiral swarm
of discrete particles, each particle in elliptic motion about
the central nucleus. The authors go further back and endeavor
to account for the origin of the spiral nebula, but this phase
of the subject is not vital to their hypothesis. However, it
conduces to clearness in presenting their hypothesis to begin
with the earlier process.

It may happen, once in a while, that two stars will collide. If
the collision is a grazing one, they say, a spiral nebula will
be formed. However, a fairly close approach of two stars will
occur in vastly greater frequency and the effect of this
approach will also be to form a spiral nebula or two such
nebulae. The authors recall that our Sun is constantly ejecting
materials to a considerable height to form the prominences, and
that the attractions of a great star passing fairly close to
our solar system would assist this process of expulsion of
matter from the Sun. A great outbreak or ejection of matter
would occur not only on the side of our Sun turned toward the
disturbing body, but on the opposite side as well, for the same
reason that tides in our oceans are raised on the side opposite
the Moon as well as on the side toward the Moon. As the Sun and
disturbing star proceeded in their orbits, the stream of matter
leaving our Sun on the side of the disturbing body would try to
follow the other star; and the stream of matter leaving the
other side of the Sun would shoot out in curves essentially
symmetrical with those in the first stream. As the disturbing
star approached and receded the paths taken by the ejected
matter would be successively along curves such as are
represented by the dotted lines in Fig. 28. At any given moment
the ejected matter would lie on the two heavy lines. The matter
would not be moving along the heavy lines, but nearly at right
angles to them, in the directions that the lighter curves are
pointing. As the ejections would not be continuous, but on the
contrary intermittent, because of violent pulsations of the
Sun's body, there would be irregularities in the two spiral
streamers. The materials drawn out of the Sun would revolve
around it in elliptic orbits after the disturbing body had
passed beyond the distance of effective disturbance, as
illustrated in Fig. 29. The orbits of the different masses
would have different sizes and different eccentricities. There
would also be a wide distribution of finely-divided material
between the main branches of the spiral. All of the widespread
gaseous matter, hot when it left the Sun, would soon become
cold, by expansion and radiation; and only the massive nuclei
would remain gaseous and hot.

I see no reason to question the efficiency of this ingenious
explanation of the origin of a spiral nebula: the close passage
of two massive stars could, in my opinion, produce an effect
resembling a spiral nebula, quite in accordance with Moulton's
test calculations upon the subject. Some of the spirals have
possibly been formed in this way (see Fig. 30); but that the
tens of thousands of spirals known to exist in the sky have
actually been produced in this manner is another question, and
one which, in my opinion, is open to grave doubt. But to this
point we shall return later.

There are marked advantages in starting the evolution of the
solar system from a spiral nebula, aside from the fact that
spirals are abundant, and therefore represent a standard
product of development. The material is thinly and very
irregularly distributed in a plane passing through the Sun, and
the motions around the Sun are all in the same direction. The
great difficulty in the Laplace hypothesis, as to the constancy
of the moment of momentum, is here eliminated. There are
well-defined condensations of nuclei at quite different
distances from the Sun. According to this hypothesis the
principal nuclei are the beginnings of the future planets. They
draw into themselves the materials with which they come in
contact by virtue of the crossings of the orbits of various
sizes and various eccentricities. The growth of the planets is
gradual, for the sweeping up and combining process must be
excessively slow. The satellites are started from those smaller
nuclei which happen to be moving with just the right speeds not
to escape entirely the attractions of the principal nuclei, nor
to fall into them. The planes of the planetary orbits and, in
general, the planes of the satellite orbits should agree quite
closely with each other, but they could differ and should
differ from that of the Sun's equator.

The authors call attention to the fact that the Sun's equator
is inclined at a small angle, 7 degrees, to the common planes
of the planetary system, and Chamberlin holds this to be one of
the strong points in favor of the planetesimal hypothesis. He
reasons thus: the star which passed close to our Sun and drew
out the planetary materials in the form of spiral streams must
have moved in the plane of the spiral; that is, in the plane of
our planetary system. Some of the materials would be drawn out
from our Sun only a very short distance and then fall back upon
the Sun. Great tidal waves would be formed on opposite sides of
the Sun, and these would try to follow the disturbing body. The
effect of these waves and of the materials which fall back
would be to change the Sun's original rotation plane in the
direction of the disturbing body's orbital plane.

Now the chance for a disturbing star's passing around our Sun
in a plane making a large angle, say from 45 degrees to 90
degrees, with the Sun's equator, is much greater than for a
small angle 0 degrees to 45 degrees. The chances are greatest
that the angle will be 90 degrees. Only those disturbing stars
which approach our Sun PRECISELY in the plane of the Sun's
equator could move around the Sun in this plane. All those
approaching along any line parallel to the Sun's equatorial
plane, but lying outside of this plane, and all those whose
directions of approach make any angle whatever with the
equatorial plane, would find it impossible to move in that
plane. That the angle under this hypothesis is only 7 degrees
is surprising, though, as we are dealing with but a single
case, we can not say, I think, that this militates either for
or against the hypothesis. We are entitled to say only that
unless the approach was so close as to cause disturbances in
our Sun to relatively great depths, the angle referred to would
have only one chance in ten or fifteen or twenty to be as small
as 7 degrees. Any disturbance which succeeded in taking out of
the Sun only 1/7 of 1 per cent. of its mass could scarcely
succeed in shifting the axis of rotation of the remaining 99
6/7 per cent. very much, I think. If the angle were 30 degrees
or 50 degrees or 80 degrees, instead of 7 degrees, the case for
the planetesimal hypothesis would be somewhat stronger.

A remarkable fact concerning the Sun is that the equatorial
region rotates once around in a shorter time than the regions
in higher latitudes require. The rotation period of the Sun's
equator is about 24 days; the period at latitude 45 degrees is
28 days; and at 75 degrees, 33 days. The planetesimal
hypothesis attributes this equatorial acceleration to the
falling back into the Sun of the materials which had been
lifted out to a short distance by the disturbing body, and to
the forward-rushing tide raised in the equatorial regions by
the disturbing body. This may well have occurred. However, we
must remember that the same phenomenon exists certainly in
Jupiter and Saturn, and quite probably in Uranus and Neptune;
that is, in all the bodies in the system that are gaseous and
free to show the effect. It seems to be the result of a
principle which has operated throughout the solar system, not
requiring, at least not directly requiring, the passage of a
disturbing star. I think the most plausible explanation of this
curious phenomenon is that great quantities of materials
originally revolving around the Sun and around each of the
planets have gradually been drawn into these bodies, by
preference into their equatorial areas. Such masses of matter
moving in orbits very close to these bodies must have traveled
with speeds vastly higher than the surface speeds of the
bodies. To illustrate, the rotational velocity of a particle
now in the Sun's surface at the equator is approximately 2 km.
per second. A small body revolving around the Sun close to his
surface, rapidly enough to prevent its falling quickly upon the
Sun, must have a velocity of more than 400 km. per second. If,
now, this small body encounters some resistance it will fall
into the Sun, and as it is traveling more than 200 times as
rapidly as the solar materials into which it drops, it will
both generate heat and accelerate the rotational velocity of
the surrounding materials. In the same way the equatorial
accelerations in Jupiter and Saturn can receive simple
explanation. The point is not necessarily in opposition to the
planetesimal hypothesis; but whatever the explanation, it ought
to apply to the planet as well as to the Sun.

If the spiral nebulae have been formed in accordance with
Chamberlin and Moulton's hypothesis, the secondary nuclei in
them must revolve in a great variety of elliptic orbits. The
orbits would intersect, and in the course of long ages the
separate masses would collide and combine and the number of
separate masses would constantly grow smaller. Moulton has
shown that IN GENERAL the combining of two masses whose orbits
intersect causes the combined mass to move in an orbit more
nearly circular than the average orbit of the separate masses,
and in general in orbit planes more nearly coincident with the
general plane of the system. Accordingly, the major planets
should move in orbits more nearly circular and more nearly in
the plane of the system than do the asteroids; and so they do.
If the asteroids should combine to form one planet the orbit of
this planet should be much less eccentric than the average of
all the present asteroid eccentricities, and the deviation of
its orbit plane should be less than the average deviation of
the present planes. We can not doubt that this would be the
case. Mercury and Mars, the smallest planets, should have,
according to this principle, the largest eccentricities and
orbital inclinations of any of the major planets. This is true
of the eccentricities, but Mars's orbit plane, contrarily, has
a small inclination. Venus and the Earth, next in size, should
have the next largest inclinations and eccentricities, but they
do not; Venus's eccentricity is the smallest of all. The
Earth's orbital inclination and eccentricity are both small.
Jupiter and Saturn, Uranus and Neptune, should have the
smallest orbital inclinations; their average inclination is
about the same as for Venus and the Earth. They should likewise
have the smallest eccentricities. Neptune, the smallest of the
four, has an orbit nearly circular; Jupiter, Saturn and Uranus
have eccentricities more than 4 times those of Venus and the
Earth. Considering the four large planets as one group and the
four small planets as another group, we find that the
inclinations of the orbits of the two groups, per unit mass,
are about equal; but the average eccentricity of the orbits of
the large planets, per unit mass, is 21 times that of the
orbits of the small planets.[1] The evidence, except as to the
asteroids and Mercury, is not favorable to the planetesimal
hypothesis, unless we make special assumptions as to the
distribution of materials in the spiral nebulae.

[2] The average eccentricity of the orbits of the four inner
planets (per unit mass) is 0.0221, and of the four outer
planets is 0.0489.



The fact that the disturbing body drew 225 times as much matter
a great distance to form the four large planets as it drew out
a short distance to form the four small planets and the
asteroids seems difficult of explanation on the planetesimal
hypothesis. However, this distribution of matter is at present
a difficulty in any of the hypotheses. The planetesimal
hypothesis explains well all west to east rotations of the
planets on their axes, but to make Uranus rotate nearly at
right angles to the plane of the system, and Neptune in a plane
inclined 135 degrees to the plane of the system, is a
difficulty in any of the hypotheses, unless special assumptions
are made to fit each case.

The authors succeed well, I think, in showing that the
satellites should prefer to revolve around their planets in the
direction of the planetary revolution and rotation, especially
for close satellites, and, on the basis of special assumptions,
in the reverse direction for satellites at a greater distance.
They show that the chances favor small eccentricities for
satellites revolving about their planets in the west to east,
or direct sense, and large eccentricities for satellites moving
in retrograde directions. The inner satellite of Mars and the
rings of Saturn make no special difficulty under the
planetesimal hypothesis.

The evidence of the comets, as bona fide members of the solar
system which approach the Sun almost, and perhaps quite,
indifferently from all directions, is that the volume of space
occupied by the parent structure of the system was of enormous
dimensions, both at right angles to the present principal plane
of the system and in that plane. We are accustomed to think of
the spiral nebulae as thin relatively to their major diameters.
To this extent the planetesimal hypothesis does not furnish a
good explanation of the origin of comets, unless we assume that
a small amount of matter was widely scattered in all directions
around the parent spiral; and this conception leads to some
apparent difficulties. The origin of the comets is difficult to
explain under any of the hypotheses.

RESUME OF HYPOTHESES

Kant's hypothesis had the great defect of trying to prove too
much. It started from matter AT REST, and came to grief in
trying to give a motion of rotation to the entire mass through
the operation of internal forces alone--an impossibility.
Kant's idea of nuclei or centers of gravitational attraction,
scattered here and there throughout the chaotic mass, which
grew into the planets and their satellites, is very valuable.

Laplace's hypothesis had the great advantage of starting with
an extended mass already in rotation, but it violated fatally
the law of constancy of moment of momentum. We should expect
this hypothesis to create a solar system free from
irregularities, very much as if it were the product of an
instrument-maker's precision lathe. The solar system as it
exists is a combination of regularities and many surprising
irregularities.

Chamberlin and Moulton's hypothesis has the advantage of a
parent mass in rotation, practically in a common plane, and
with the materials distributed at distances from the nucleus as
nearly in harmony with the known distribution of matter in the
solar system as we care to have them, except perhaps as to the
comets. In effect it retains all the advantageous qualities of
Kant's proposals. It seems to have the flexibility required in
meeting the irregularities that we see in our system.

CONCERNING THE ORIGIN OF SPIRAL NEBULAE

I think it is very doubtful whether the spiral nebulae have in
general been formed by the close approaches of pairs of stars,
as the authors have postulated for the assumed solar spiral.[2]
The distribution of the spirals seems to me to negative the
idea. To witness the close approach of two stars we must look
in the direction where the stars are. To the best of
present-day knowledge the stars are in a spheroid whose longer
axes are coincident with the plane of the Milky Way. If this is
so, the close approach of pairs of stars should occur
preeminently in the Milky Way, and we should find the spirals
prevailingly in and near the Milky Way. This is precisely where
we do not find them. In fact, they seem to abhor the Milky Way.
The new stars, which are credibly explained as the products of
collisions of stars with nebulae, are found preeminently in the
Milky Way and almost negligibly in the regions outside of the
Milky Way. Again, the spirals are believed to be, on the whole,
of enormous size. They are too far away to let us measure their
distances by the usual methods, and they move too slowly on the
surface of the sphere to have let us determine their proper
motions. Slipher's recent work with a spectrograph seems to
show that the dozen spirals observed by him are moving with
high speeds of approach and recession; from 300 km. per second
approach in the case of the Andromeda nebula to 1,100 km. per
second recession in the case of several objects. If the spirals
are moving at random their speeds at right angles to the line
of sight must be even greater than their speeds of approach and
recession. Unless they are very distant bodies their proper
motions should be detected by observations extending over only
a few years. My colleague Curtis has this year compared recent
photographs of some 25 spirals with photographs of the same
object made by Keeler fifteen years ago. They reveal no
appreciable proper motions, or rotations. In this same interval
Neptune has revolved more than 30 degrees. Slipher has recently
measured the rotational speed of one "spindle" nebula, believed
to be a spiral. He finds it to be enormously rapid; no motions
in the solar system approach it in magnitude. The evidence is
to the effect that the spirals are in general very far away;[3]
perhaps on or beyond the confines of our stellar system, but
not certainly so. Accordingly, we are led to believe that the
spirals studied thus far have diameters 20 times or 100 times,
or in some cases several thousand times, the diameter of our
solar system. It is difficult to avoid the conclusion that in
general they are immensely more massive than is our solar
system. The spiral which has been assumed as the forerunner of
our system must have been of diminutive size as compared with
the larger and brighter spirals which we see to-day.

[2] It would seem that all rotating nebulae should in reality
possess some of the attributes of spiral motion. Whether the
spiral structure should be visible or invisible to a
terrestrial observer would depend upon the sizes and distances
of the nebulae, upon the distribution of materials composing
them, and perhaps upon other factors. See developed the
hypothesis that spiral nebulae owe their origin to the
collision of two nebulae. Collisions of this kind could readily
occur because of the enormous dimensions of the nebulae, and
motions of rotation and consequently spiral structure might
readily result therefrom. The abnormally high speeds of the
spiral nebulae are apparently a very strong objection to the
hypothesis.

[3] Bohlin found a parallax of 0"17 for the Andromeda Nebula,
and Lampland thinks that Nebula N.G.G. 4594 has a proper motion
of approximately 0"05 per annum.



We are sadly in need of information concerning the constitution
of the spiral nebulae. Their spectra appear to be prevailingly
of the solar type, except that a very small proportion contain
some bright lines in addition to the continuous spectrum. So
far as their spectra are concerned, they may be great clusters
of stars, or they may consist each of a central star sending
its light out upon surrounding dark materials and thus
rendering these materials visible to us. The first alternative
is unsatisfactory, for all parts of spirals have hazy borders,
as if the structure is nebulous or consists of irregular groups
of small masses; and the second alternative is unsatisfactory,
for in many spirals the most outlying masses seem to be as
bright as masses of the same areas situated only one half as
far from the center, whereas in general the inner area should
be at least four times as bright as the outer area. All
astronomers are ready to confess that we do not know much about
the conditions existing in spiral nebulae.

THE EARTH-MOON SYSTEM

Our Earth and Moon form a unique combination in that they are
more nearly of the same size than are any other planet and its
satellites in our system. It required a 26-inch telescope on
the Earth to discover the tiny moons of Mars; but an astronomer
on Mars does not need any telescope to see the Earth and Moon
as a double planet--the only double planet in the solar system.

According to the Kantian school of hypotheses the Earth and
Moon owe their unique character to the accident that two
centers of condensation--two nuclei--not very unequal in mass,
were formed close to each other and were endowed with or
acquired motions such that they revolved around each other.
They drew in the surrounding materials; one of the two bodies
got somewhat the advantage of the other in gravitational
attraction; it succeeded in building itself up more than the
other nucleus did; and the Earth and the Moon were the result.

According to the Laplacean hypothesis, on the contrary, the
Earth and Moon were originally one body, gaseous and in
rotation. This ball of gas radiated heat, diminished in size,
rotated more and more rapidly, and finally abandoned a ring of
nebulosity, which later broke up and eventually condensed into
one mass called the Moon. The central mass composed the Earth.
It is a curious fact that Venus, which is only a shade smaller
than the Earth, should not have divided into two bodies
comparable with the Earth and Moon. Have the tides on Venus
produced by the Sun always been strong enough to keep the
rotation and revolution periods equal, as they are thought to
be now, and thus to have given no opportunity for a rapidly
rotating Venus to divide into two masses?

A third hypothesis of the Moon's origin is due principally to
Darwin. He and Poincare have shown that a great rotating mass
of fluid matter, such as the Earth-Moon could be assumed to
have been, by cooling, contracting and increasing rotation
speed, would, under certain conditions thought to be
reasonable, become unstable and eventually divide into two
bodies revolving around their common center of mass, at first
with their surfaces nearly in contact. Here would begin to act
a tide-raising force which must have played, according to
Darwin's deductions, a most important part in the further
history of the Earth and Moon. The Earth would produce enormous
tides in the Moon, and the Moon much smaller tides in the
Earth. Both bodies would contract in size, through loss of
heat, and would try to rotate more and more rapidly. The two
rotating bodies would try to carry the matter in the tidal
waves around with the rest of the materials in the bodies, but
the pull of each body upon the wave materials in the other
would tend to slow down the speed of rotation. The tidal
resistance to rotation would be slight if the bodies at any
time were attenuated gaseous masses, for the friction within
the surface strata would be slight. Nevertheless, there would
eventually be a gradual slowing down of the Moon's rotation, a
gradual slowing down of the Earth's rotation, and a slow
increase in the distance between the two bodies. In other
words, the Moon's day, the Earth's day and our month would
gradually increase in length. Carried to its logical
conclusion, the Moon would eventually turn the same face to the
Earth, the Earth would eventually turn the same face to the
Moon, and the Earth's day and the Moon's day would equal the
month in length. The central idea in this logic is as old as
Kant: in 1754 he published an important paper in which he said
that tidal interactions between Earth and Moon had caused the
Moon to keep the same face turned toward us, that the Earth's
day was being very slowly lengthened, and that our planet would
eventually turn the same face to the Moon. Laplace, a
half-century later, proposed the action of such a force in
connection with the explanation of lunar phenomena, and
Helmholtz, just 100 years after Kant's paper was published,
lent his support to this principle; but Sir George Darwin has
been the great contributor to the subject. His popular volume,
"The Tides," devotes several chapters to the effects of tidal
friction upon the motions of two bodies in mutual revolution.
We must pass over the difficult and complicated intermediate
steps to Darwin's conclusions concerning the Earth and Moon,
which are substantially as follows: the Earth and Moon were
originally much closer together than they now are: after a very
long period of time, amounting to hundreds of millions of
years, the Moon will revolve around the Earth in 55 days
instead of in 27 days as at present; and the Moon and Earth
will then present the same faces constantly to each other. The
estimated period of time required, and the final length of day
and month, 55 days, are of course not insisted upon as accurate
by Darwin.

These tidal forces were unavoidably active, it matters not if
the Earth and Moon were originally one body, as Laplace and
Darwin have postulated, or originally two bodies, growing up
from two nuclei, in accordance with the Kantian school. Whether
these forces have been sufficiently strong to have brought the
Earth and Moon to their present relation, or will eventually
equalize the Moon's day, the Earth's day, and the month, is a
vastly more difficult question. Moulton's researches have cast
serious doubt upon this conclusion. All such investigations are
enormously difficult, and many questionable assumptions must be
made if we seek to go back to the Moon's origin, or forward to
its ultimate destiny.

Tidal waves, in order to be effective in reducing the
rotational speed of a planet, must be accompanied by internal
friction; and this requires that the planet be to some extent
inelastic. It was the view of Darwin and others that the
viscous state of the Earth and Moon permitted wave friction to
come into play. Michelson has recently proved that the Earth
has a high degree of elasticity. It deforms in response to
tidal forces, but quickly recovers from the action of these
forces. It therefore seems that the rate of tidal evolution of
the Earth-Moon system at present and in the future must be
extremely slow, and possibly almost negligible. What the
conditions within the Earth and Moon were in the distant past
is uncertain, but these bodies probably passed through viscous
stages which endured through enormously long periods of time.
No one seriously doubts that Jupiter, Saturn, Uranus and
Neptune are now largely gaseous, and that they will evolve,
through various degrees of viscosity, into the solid and
comparatively elastic state. It is natural to assume that the
Earth has already passed through an analogous experience.

The Moon turns always the same hemisphere toward the Earth.
Observations of Venus and Mercury are prevailingly to the
effect that those planets always turn the same hemispheres
toward the Sun. Many, and perhaps all, of the satellites of
Jupiter and Saturn seem to turn the same hemispheres always
toward their respective planets. This widely prevailing
phenomenon is no doubt due to a widely prevailing cause, which
astronomers have all but unanimously attributed to tidal
action.

BINARY STAR SYSTEMS

That an original mass actually divided to form the Earth and
Moon, according to the Laplacian or the Darwin-Poincare
principle, seems to be extremely doubtful, especially on
account of their diminutive sizes, and I greatly prefer to
think that the Earth and Moon were built up from two nuclei;
but that very much greater masses, masses larger on the average
than our Sun, composing highly attenuated stars, have divided
each into two masses to form many or most of our double stars,
I firmly believe. The two component stars would in such a case
at first revolve around each other with their surfaces almost
or quite in contact. Tidal forces would very gradually cause
the bodies to move in orbits of larger and larger size, with
correspondingly longer periods of revolutions, and the orbits
would become constantly more eccentric. While these processes
were under way the component bodies would be radiating heat and
growing smaller, and their spectra would be changing into the
more advanced types. We can not hope to watch such changes as
they occur, but we can, I think, find abundant illustrations of
these processes in the double stars. I have given reasons for
believing that one star in every two and one half, as a minimum
proportion, is not the single star which it appears to be to
the eye or in the telescope, but is a system of two or more
suns in mutual revolution. The formation of double stars,
therefore, is not a sporadic process: it is one of the
straightforward results of the evolutionary process.

Some of the variable stars offer strong evidence as to the
early life of the double stars. The so-called beta Lyrae
variables vary continuously in brightness, as if they consist
in each case of two stars so close together that their surfaces
are actually in contact in some pairs and nearly in contact in
others, so that from our point of view the two stars mutually
eclipse each other. When the two stars are in line with us we
have minimum brightness. When they have moved a
quarter-revolution farther, and the line joining them is at
right angles to our line of sight, so to speak, we have maximum
brightness. In every known case the beta Lyrae pairs of stars
have spectra of the very early types. Some of them even contain
bright lines in their spectra. The densities of these great
stars are known to be exceedingly low, in some cases much lower
on the average than that of the atmosphere which we breathe.

About 80 Algol variable stars are known. These are double stars
whose light is constant except during the short time when one
of the components in each system passes between us and the
other component. All double stars would be Algol variables if
we were exactly in the planes of their orbits. That so few
Algols have been observed amongst the tens of thousands of
double stars, is easily explained. The two component stars in
the few known Algol systems are so great in diameter, in
proportion to the size of their orbits, that eclipses are
observable throughout a wide volume of space, and the eclipses
are of long duration relatively to the revolution period. Their
densities are, so far as we have been able to determine them,
on an average less than 1/10th of the Sun's density. Let us
note well that their spectra, so far as we have been able to
determine them, are of the early types; mostly helium and
hydrogen stars, and a very few of the Class F, intermediate
between the hydrogen and solar stars. There are no known Algols
of the Classes G, K, and M: these stars are very condensed and
therefore small in size, as compared with stars of Classes B
and A; and the components of double stars of these classes are
on the average much denser and therefore smaller in size than
the components in Classes B and A double stars; the components
are much farther apart in Classes G to M doubles than in
Classes B and A doubles; and for these reasons eclipses in
Classes G to M doubles occur but rarely for observers scattered
throughout space. It is difficult to avoid the conclusion that
the components of double stars separate more and more widely
with the progress of time. The conclusions which we have
earlier drawn from visual double stars are in full harmony with
the argument.

It is agreed by all, I think, that tidal action has been
responsible for at least a part of the separation of the Earth
and Moon, for at least a part of the gradual separation of the
components of double stars, and for at least a part of the
eccentricity of their orbits. See's investigations of 25 years
ago led him to the conclusion that this force is sufficient to
account for all the observed separation of the components of
double stars, and for the well-known high eccentricities of
their orbits. In recent years Moulton and Russell have
seriously questioned the sufficiency of this force to account
for the major part of the separation and eccentricity in the
double star systems. I think, however, that if the tidal force
is not competent to account for the observed facts as
described, some other separating force or forces must be found
to supply the deficiency.

THE FORMATION OF THE EARTH

Does the condition of the Earth's interior give evidence on the
question of its origin? There are certain important facts which
bear upon the problem.

1. The evidence supplied by the volcanoes, by the hot springs,
and by the rise in temperature as we go down in all deep mines,
is unmistakably to the effect that there is an immense quantity
of heat in the Earth's interior. Near the surface the
temperature increases at the average of 1 degrees Centigrade
for every 30 meters of depth. If this rate were maintained we
should at 60 km. in depth arrive at a temperature high enough
to melt platinum, the most refractory of the known metals. What
the law of temperature-increase at great depths is we do not
know, but the temperature of the Earth's deep interior must be
very high.

2. The pressures in the Earth increase from zero at the surface
to the order of 3,000,000 atmospheric pressures at the center.
We know that rock structure, or iron or other metals, can be
slightly compressed by pressure, but the experiments at very
high pressures, notably those conducted by Bridgman, give no
indications that matter under such pressures breaks down and
obeys different or unknown laws. It should be said, however,
that laboratory pressure-effects alone are not a safe guide as
to conditions within the Earth, where high pressures are
accompanied by high temperature. Unfortunately it has not been
found possible to combine the high-temperature factor with the
high-pressure factor in the laboratory experiments. It is well
known that the melting points of metals, including rocks,
increase with increase of pressure; and although the
temperatures in the Earth's interior are very high, it is easy
to conceive that the materials of the Earth's interior are
nevertheless in the solid state, or that they act like solids,
because of the high pressures to which they are subjected.

3. The specific gravity of the entire Earth is 5.5 on the scale
of water as one, whereas the density of the stratified rocks
averages only 2.75; that is, the stratified rocks have but one
half the density of the Earth as a whole. The basaltic rocks
underlying the stratified attain occasionally the density 3.1,
and perhaps a little higher. It follows absolutely that the
density of the materials of the Earth's interior must be
considerably in excess of 5.5. If the interior is composed
chiefly of substances which are plentiful in the Earth's
surface strata, our choice of materials which principally
compose the interior is reduced to a few elements, notably the
denser ones.

4. The observed phenomena of terrestrial precession can not be
explained on the basis of an Earth with a thin solid surface
shell and a liquid interior, for the attractions of the Moon
and Sun upon the Earth's equatorial protuberance would cause
the surface shell to shift over the fluid interior, instead of
swinging the entire Earth.

5. If the Earth consisted of a thin solid shell upon a liquid
interior there would be tides in the liquid interior, the crust
would yield to these tides almost as if it were composed of
rubber, and the ocean tides would be only an insignificant
amount larger than the land tides. As a result we should not
see the ocean tides; their visibility depends upon the contrast
between the ocean tides and the land tides. If the Earth were
absolutely unyielding from surface to center the ocean tides
would be relatively 50 per cent. higher than we now see them.
The conclusion from these facts is that the Earth yields to the
tidal forces a little less than if it were a solid ball of
steel, supposing that the well-known rigidity and density
existed from surface to center of the ball. This result is
established by Darwin's and Schweydar's studies of ocean tides,
by studies of the tides in the Earth's surface strata made by
Hecker, Paschwitz and others, and by Michelson's recent
extremely accurate comparison of land and water tides.
Michelson's results establish further that the Earth is highly
elastic: though distortion is resisted, there is yielding, but
the original form is recovered quickly, almost as quickly as a
perfectly elastic body would recover.

6. Some 25 years ago it was discovered by Kustner that the
latitudes of points on the Earth's surface are changing slowly.
Chandler proved that these variations pass through their
principal cycle in a period of 427 days. The entire Earth
oscillates slightly in this period. The earlier researches of
Euler had shown that the Earth would have a natural oscillation
period of 305 days provided it were an absolutely rigid body.
Newcomb showed that the period of oscillation would be 441 days
if the Earth had the rigidity of steel. As the observed
oscillation requires 427 days, Newcomb concluded that the Earth
is slightly more rigid than steel.

7. The first waves from a very distant earthquake come to us
directly through the Earth. The observed speeds of transmission
are the greater, in general, the more nearly the earthquake
origin is exactly on the opposite side of the Earth from the
observer; that is, the speeds of transmission are greater the
nearer the center of the Earth the waves pass. Now, we know
that the speeds are functions of the rigidity and density of
the materials traversed. The observed speeds require for their
explanation, so far as we can now see, that the rigidity of the
Earth's central volume be much greater than that of steel, and
the rigidity of the Earth's outer strata considerably less than
that of steel. Wiechert has shown that a core of radius 4,900
km. whose rigidity is somewhat greater than that of steel and
whose average density is 8.3, overlaid by an outer stony shell
of thickness 1,500 km. and average density 3.2, would satisfy
the observed facts as to the average density of the Earth, as
to the speeds of earthquake waves, as to the flattening of the
Earth,--assuming the concentric strata to be homogeneous in
themselves,--and as to the relative strengths of gravity at the
Poles and at the Equator. The dividing line, 1,500 km. below
the surface--1,600 km. would be just one fourth of the way from
the surface to the center--places a little over half the volume
in the outer shell and a little less than half in the core.
Wiechert did not mean that there must be a sudden change of
density at the depth of 1,500 km., with uniform density 8.3
below that surface and uniform density 3.2 above that surface.
The change of density is probably fairly continuous. It was
necessary in such a preliminary investigation to simplify the
assumptions. The observational data are not yet sufficiently
accurate to let us say what the law of increase in density and
rigidity is as we pass from the surface to the center.

8. The phenomena of terrestrial magnetism indicate that the
distribution of magnetic materials in the Earth is far from
uniform or symmetrical; the magnetic poles are distant from the
Earth's poles of rotation; the magnetic poles are not opposite
each other; the lines of equal intensity as to all the magnetic
components involved run very irregularly over the Earth's
surface. There is reason to believe that iron in the deep
interior of the Earth, in view of its high temperature, is
devoid of magnetic properties, but we must not state this as a
fact. We know that iron is very widely, but very irregularly
spread throughout the Earth's outer strata. Whatever may be the
main factors in making the Earth a great magnet, to whatever
extent the rotation factor may be important, the Earth's
magnetic properties point strongly to a very irregular
distribution of magnetic materials in the outer strata where
the temperatures are below that at which magnetic materials
commonly lose their polarity.

9. Irregularities in the direction of the plumb-line and in the
force of gravity as observed widely and accurately over the
Earth's surface indicate that the surface strata are very
irregular as to density. To harmonize the observed facts
Hayford has shown the need of assuming that the heterogeneous
conditions extend down to a depth of 122 km. from the surface.
Below that level the Earth's concentric strata seem to be of
approximately uniform densities.

10. The radio active elements have been found by Strutt and
others in practically all kinds of rock accessible to the
geologists, but they are not found in significant quantities in
the so-called metals which exist in a pure state. These
radioactive elements are liberating heat. Strutt has shown that
if they existed down to the Earth's center in the same
proportion that he finds in the surface strata they would
liberate a great deal more heat than the body of the Earth is
now radiating to outer space. The conclusion is that they are
restricted to the strata relatively near the Earth's surface,
and are not in combination with the materials composing the
Earth's core. They have apparently found some way of coming to
the higher levels. Chamberlin suggests that as they liberate
heat they would raise surrounding materials to temperatures
above the normals for their strata, and that these expanded
materials would embrace every opportunity to approach the
surface of the Earth, carrying the radioactive substances with
them.

The evidence is exceedingly strong, and perhaps irresistible,
to the effect that the Earth is now solid, or acts like a
solid, from surface to center, with possibly local, but on the
whole negligible, pockets of molten matter here and there; and
further, that the Earth existed in a molten, or at the least a
thickly plastic, state throughout a long part of its life. The
nucleus, whether gaseous or meteoric, from which I believe it
has grown, may have been fairly hot or quite cold, and the
materials which were successively drawn into the nucleus may
have been hot or cold: heat would be generated by the impacts
of the incoming materials; and as the attraction toward the
center of the mass became strong, additional heat would be
generated in the contraction process. The denser materials have
been able, on the whole, to gravitate to the center of the
structure, and the lighter elements have been able, on the
whole, to rise to and float upon the surface very much as the
lighter impurities in an iron furnace find their way to the
surface and form the slag upon the molten metal. The lighter
materials which in general form the surface strata are solid
under the conditions of solids known to us in every-day life.
The interior is solid or at least acts as a solid, because the
materials, though at high temperatures, are under stupendous
pressures. If the pressures were removed the deep-lying
materials would quickly liquefy, and probably even vaporize.

If the Earth grew from a small nucleus to its present size by
the extremely gradual drawing-in of innumerable small masses in
its neighborhood, the process would always be slow; much slower
at first when the small nucleus had low gravitating powers,
more rapid when the body was of good size and the store of
materials to draw upon plentiful,and gradually slower and
slower as the supply of building materials was depleted.
Meteoric matter still falls upon and builds up the Earth, but
at so slow a rate as to increase the Earth's diameter an inch
only after the passage of hundreds of millions of years. If the
Earth grew in this manner, the growth may now be said to be
essentially complete, through the substantial exhaustion of the
supply of materials.

Whether the Earth of its present size was ever completely
liquefied, that is, from center to surface, at one and the same
time, is doubtful. The lack of homogeneity, as indicated by the
plumb-line, gravity, terrestrial magnetism and radiaoctive
matter, extending in a perceptible degree down to 122 km., and
quite probably in lesser and imperceptible degree to a much
greater depth, is opposed to the idea.

Solidification would respond to the fall of temperature down to
the point required under the existing high pressures, and it is
probable that the solidification began at the center and
proceeded outwards. It is natural that the plastic state should
have developed and existed especially during the age of most
rapid growth, for this would be the age of most rapid
generation of heat. Later, while the rate of growth was
declining, the body could probably have solidified slowly and
successively from center out to surface. In later slow
depositions of materials, the denser substance would not be
able to sink down to the deepest strata: they must lie within a
limited depth and horizontal distance from where they fell, and
the outer stratum of the Earth would be heterogeneous in
density.

The simplest hypothesis we can make concerning the Earth's deep
interior is that the chief ingredient is iron; perhaps a full
half of the volume is iron. The normal density of iron is 7.8,
and of rock formations about 2.8. If these are mixed, half and
half, the average density is 5.3. Pressures in the Earth should
increase the density and the heat in the Earth should decrease
the density. The known density of the Earth is 5.5. We know
that iron is plentiful in the Earth's crust, and that iron is
still falling upon the Earth in the form of meteorites. The
composition of the Earth as a whole, on this assumption, is
very similar to the composition of the meteorites in general.
They include many of the metals, but especially iron, and they
include a large proportion of stony matter. Iron is plentiful
in the Sun and throughout the stellar universe. Why should it
not be equally plentiful in the materials which have coalesced
to form the Earth? It is difficult to explain the Earth's
constitution on any other hypothesis.

The Earth's form is that which its rotation period demands.
Undoubtedly if the period has changed, the form has changed.
Given a little time, solids under great pressure flow quite
readily into new forms. Now any great slowing-down of the
Earth's rotation period within geological times would be
expected to show in the surface features. The strata should
have wrinkled, so to speak, in the equatorial regions and
stretched in the polar regions, if the Earth changed from a
spheroid that was considerably flatter than it now is, to its
present form. Mountains, as evidence of the folding of the rock
strata, should exist in profusion in the torrid zone, and be
scarce in or absent from the higher latitudes of the Earth.
Such differential effects do not exist, and it seems to follow
that changes in the Earth's rotation period and in its form
could have been only slight while the stratification of our
rocks was in progress.

Geologists estimate from the deposition of salt in the oceans,
and from the rates of denudation and sedimentation, that the
formation of the rock strata has consumed from 60,000,000 to
100,000,000 years. If the Earth had substantially its present
form 80,000,000 years ago we are safe in saying that the period
of time represented in the building up of the Earth from a
small nucleus to its present dimensions has been vastly longer,
probably reckoned in the thousands of millions of years.

For more than a century past the problem of the evolution of
the stars, including the solar system and the Earth, has
occupied the central place in astronomical thought. No one is
bold enough to say that the problem has been solved. The chief
difficulty proceeds from the fact that we have only one Earth,
one solar system and one stellar system available for tests of
the hypotheses proposed; we should like to test them on many
systems, but this privilege is denied us. However, the search
for the truth will undoubtedly proceed at an ever increasing
pace, partly because of man's desire to know the truth, but
chiefly, as Lessing suggested, because the investigator finds
an irresistible satisfaction in the process. There is always
with him the certainty that the truth is going to be
incomparably stranger and more interesting than fiction.



A METRICAL TRAGEDY

BY DR. JOS. V. COLLINS

STEVENS POINT, WIS.

THE war in Europe has opened up a large field of trade in South
America. Three things especially stand in the way of its
development, viz., the absence of a proper credit system, the
failure to make goods of the kind demanded and third, the use
of our antiquated system of weights and measures, all the South
American countries employing the metric system. Of these three
obstructing influences, the first two are in a fair way to be
obviated soon; not so the last.

It is the use by our modern progressive country of an ancient
system of weights and measures which it is here proposed to
discuss and show up as an absurdity. Our present system is
organized and set forth in arithmetics under some fifteen
so-called "tables." These tables are all different and there is
no uniformity in any one table. Only one unit suggests
convenience in reductions, viz., hundredweight. It is easy to
reduce from pounds to hundredweight and vice versa. Some fifty
ratio numbers have to be memorized or calculated from other
memorized numbers to make the common needed reductions. History
shows that ancient Babylonia had tables superior to those now
in use, and ancient Britain a decimal scale which was crowded
out by our present system.

The metric system of weights and measures was developed in
France about 1800 and has come to be employed over all the
civilized world except in the United States, Great Britain and
Russia. The system was legalized in the United States in 1866
but not made mandatory and here we are fifty years later using
the old system, with most of the civilized world looking on us
with more or less scorn because of our belatedness.

In this age everywhere the cry is efficiency, always more
efficiency. Ten thousand improvements and labor-saving devices
are introduced every day. But here is an improvement and
labor-saving device which would affect the life of every person
in the land and in many instances greatly affect such persons'
lives, and yet almost no one really knows anything about the
matter.

So let us now consider the good points in the metric system
(each implying corresponding elements of great weakness in the
common system), and then study briefly what stands in the way
of its adoption in this country. These good points are:

First, the metric units have uniform self-defining names (cent,
mill, meter and five more out of the eleven terms used already
familiar to us in English words), are always the same in all
lands, known everywhere, and fixed with scientific accuracy.

Second, every REDUCTION is made almost instantaneously by
merely moving the decimal point. There are no reductions
performed by multiplying by 1,728 or 5,280, etc., or dividing
by 5 1/2, 30 1/4 or 31 1/2, etc., and hence there is A GREAT
SAVING in the labor and time of making necessary calculations.

Third, there are but FIVE tables in the metric system proper,
these taking the place of from twelve to fifteen in our system
(or lack of it). These are linear, square, cubic, capacity and
weight.

Fourth, any one table is about as easy to learn as our United
States money table, and after one is learned, it is much easier
to learn the others, since the same prefixes with the same
meanings are used in all.

Fifth, the weights of all objects are either known directly
from their size, or can be very quickly found from their
specific gravities.

Sixth, the subject is made so much easier for children in
school that a conservative expert estimate of the saving is two
thirds of a year in a child's school life. The rule in this
country is eight years of arithmetic, the arithmetic occupying
about one fourth of the child's activity. With metric
arithmetic substituted for ours, what it now takes two years to
prepare for, could be easily done in 1 1/3 years. This involves
an enormous waste of money and energy every twelvemonth.

Seventh, only ONE set of measures and ONE set of weights are
needed to measure and weigh everything, and ONE set of machines
to make things for the world's use. There would be no
duplication of costly machinery to enter the foreign trade
field, thus securing enormous saving. It is well known that the
United States and Great Britain have lost a vast amount of
foreign commerce in competition with Germany and France,
because of their non-use of the metric units. Britain realizes
this and is greatly concerned over the situation.

Eighth, every ordinary practical problem can be solved
conveniently on an adding machine. Our adding machines are used
almost solely for United States money problems.

Ninth, no valuable time is lost in making reductions from
common to metric units, or vice versa, either by ourselves or
foreigners. To make our sizes in manufactured goods concrete to
them foreign customers have to reduce our measures to theirs
and this is a weariness to the flesh.

Tenth, the metric system is wonderfully simple. All the tables
with a rule to make all possible reductions can be put on a
postal card.[1]

[1] See article by the writer in Education (Boston), Dec.,
1894.



The metric weights and measures constitute a SCIENTIFIC SYSTEM;
our weights and measures are a DISORGANIZATION. Naturally one
can expect a GREAT SAVING OF TIME, THOUGHT AND LABOR from the
use of a system, and this is the fact. If one dared introduce
ordinary arithmetical problems into an article like this, it
would be easy to show by examples how a person has to be
something of a master of common fractions in order to solve in
our system common every-day problems, whereas in the metric
system nearly everything is done very simply with decimals. In
our system a mechanic after making a complicated calculation
with common fractions is as likely as not to get his result in
sixths, or ninths, etc., of an inch, whereas his rule reads to
eighths, or sixteenths, and he must reduce his sixths, or
ninths, to eighths, or sixteenths, before he can measure off
his result. In the metric system results always come out in
units of the scale used. The metric system measures to
millimeters or to a unit a trifle larger than a thirty-second
of an inch. In our system one is likely to avoid sixteenths or
thirty-seconds on account of the labor of calculation. Then,
besides, the amount of figuring is so much less in the metric
system. Take the case of a certain problem to find the cubical
contents of a box. Our solution calls for 80 figures and the
metric for 35, and this is a typical case, not one specially
selected. Thus, metric calculations, while only from one third
to two thirds as long, are likely to be two or three times as
accurate, are far easier to understand, and the results can be
immediately measured off. Hence, we waste time in these four
ways. Shakespeare in Hamlet says: "Thus conscience does make
cowards of us all." In like vein it might be said: Thus custom
(in weights and measures) doth make April fools of us all. It
is no exaggeration to say that counting grown-ups solving
actual problems and children solving problems in school we are
sent on much more than a billion such April fool errands round
Robin Hood's barn every year.

Noting how much time is saved in making simple every-day
calculations by using the metric system, suppose that we assume
of the 60 or more millions of adults in active life in this
country, on the average only one in 60 makes such calculations
daily and that only twenty minutes' time is saved each day. Let
us suppose that the value of the time of the users is put at
$2.40 per day or 10 cents for 20 minutes. Then 1,000,000 users
would save $100,000 per day or $30,000,000 per year. But
perhaps some one is saying that much of this time is not really
saved, since many persons are paid for their time and can just
as well do this work as not. The answer to this is that in many
instances such calculations take the time of OTHERS as well as
the person making the calculation. Occasionally a contractor
might hold back, or work to a disadvantage a gang of a score of
workmen while trying to solve a problem that came up
unexpectedly.

An estimate of the value of all weighing and measuring
instruments places the sum at $150,000,000. Thus, we see that
in five years, merely by a saving in TIME--for time is
money--all metric measuring and weighing instruments could be
got NEW at no extra expense. This estimate of the cost of
replacing our weighing and measuring instruments by new metric
ones and of saving time has been made by others with a similar
result.

A matter of very much more importance than that just discussed
is the extra unnecessary expense put upon education, viz., two
thirds of a year for every child in the land. Presumably if the
metric system were in use with us, all our children would stay
in school as long as they now do, thus getting two thirds of a
year farther along in the course of study. Actually, if
arithmetic were made more simple, vast numbers would; stay
longer, since they would not be driven out of school by the
terrible inroads on their interest in school work by dull and
to them impossible arithmetic. If metric arithmetic texts were
substituted for our present texts, it is safe to say children
would average one full year more of education. What the
increased earning power would be from this it would be hard to
estimate, but clearly it would be a huge sum.

Consider also how much more life would be worth living for
children, teachers and parents if a very large portion of
arithmetical puzzles inserted to qualify the children to
understand our crazy weights and measures were cut out of our
text-books. If we were to adopt the metric system, literally
millions of parents would be spared worry, and shame, and fear
lest Johnny fail and drop out of school, or Mary show
unexpected weakness and have to take a grade over again;
uncounted thousands of teachers would be saved much gnashing of
teeth and uttering of mild feminine imprecations under their
breath; and, best of all, the children themselves would be
saved from pencil-biting, tears, worries, heartburns, arrested
development, shame and loss of education!

A committee of the National Educational Association has
recently reported that Germany and France are each two full
years ahead of us in educational achievement, that is, children
in those countries of a certain age have as good an education
as our children which are two years the foreign childrens'
seniors. Surely one of these years is fully accounted for by
the inferiority of our American ARITHMETIC and SPELLING. This
much, at least, of the difference is neither in the children
themselves, nor in the lack of preparation of our teachers, nor
in educational methods.

Professor J. W. A. Young, of the University of Chicago, in his
work on "Mathematics in Prussia," says: "In the work in
mathematics done in the nine years from the age of nine on, we
Americans accomplish no more than the Prussians, while we give
to the work seven fourths of the time the Germans give."
Professor James Pierpont, of Yale, writing in the Bulletin of
the American Mathematical Society (April, 1900), shows a like
comparison can be made with French instruction. Pierpont's
table exhibits only one hour a week needed for arithmetic for
pupils aged 11 and 12! As the advertisements sometimes say,
there must be a reason.

But if the children are kept in school two thirds of a year
longer somebody pays for this extra expense. Now children do
not drop out of school until they are about 12 years of age and
have both appetites and earning power. The number of these
children that drop out each year is probably about 2 1/2
millions. Of this number let us say 1 1/2  millions would
become wage earners, thus passing from the class that are
supported to the class that support themselves and earn a small
wage besides. We have then three items in this count: (1) The
cost to the state in taxes for the education of 2 1/2 million
for two thirds of a year, or $50,000,000; (2) The cost to the
parents for support of 1 1/2 millions for two thirds of a year
at $67 each, or $100,000,000; (3) The wages of 1 1/2  millions
over and above the cost of their support, say $50 each, or
$75,000,000.

The above figures are put low purposely so that they can not be
criticized. It should be remembered that 46 per cent. of our
population is agricultural, and that on the farm, youths of
from 13 to 15 very often do men's and women's work: also that
in many manufacturing centers great numbers of children get
work at relatively good wages, and that the number of
completely idle children out of school is not large.

With these figures in hand let us consider now a kind of debit
and credit sheet against and for our present system of weights
and measures.

Commenting for a moment on the credit side of the above ledger
account, it can be said that recent psychology shows
conclusively that training in common fractions and weights and
measures can not be of much practical help as so-called
culture, or training for learning other things, unless those
other things are closely related to them, and there are not
many things in life so related to them once we had dropped our
present weights and measures.

It may be complained that the expense of changing to the new
system is not taken account of in the above table. The reason
is that that expense would occur once for all. The above table
deals with the ANNUAL cost of our present medieval system.

One powerful reason for the adoption of the metric system
different in character from the others is the ease of cheating
by the old system. In the past the people have been
unmercifully abused through short weights and measures. Many of
the states have taken this matter up latterly and prosecuted
merchants right and left. Nine tenths of this trouble would
disappear with the new system in use.

Let us consider now for a little time the reasons why the
metric system has not been accepted and adopted for use in the
United States. Evidently the great main reason has been that
the masses of the people, in fact all of them except a very
small educated class in science are almost totally uninformed
on this whole question. Such articles as have been published
have almost invariably appeared in either scientific, technical
or educational magazines, mostly the first, so that there has
been no means of reaching the masses, or even the school
teachers with the facts. For another reason the United States
occupies an isolated position geographically, and our people do
not come into personal contact with those in other countries
using the metric system. But there is still another potent
reason. After the United States government legalized the metric
system in 1866, all the school books on arithmetic began
presenting the topic of the metric system, and, quite
naturally, they did it by comparing its units with those of our
system and calling for cross reductions from one system to the
other. No better means of sickening the American children with
the metric system could have been devised. Multitudes of the
young formed a strong dislike for the foreign system with its
foreign names, and could not now be easily convinced that it is
not difficult to learn. Every school boy knows how easy it is
to learn United States money. The boy just naturally learns it
between two nights. The whole metric system UNDER FAVORABLE
CONDITIONS is learned nearly as easily. By favorable conditions
is meant the constant use of the system in homes, schools,
stores, etc. These favorable conditions, of course, we have
never had.

In 1904 an earnest effort was made again both in this country
and Great Britain to have the metric system adopted for general
use. The exporting manufacturers in both countries grew much
concerned over the whole situation. A petition to have the
metric system adopted in Great Britain was signed by over
2,000,000 persons. A bill to make the system mandatory was
passed by the House of Lords and its first reading in the House
of Commons. The forces of conservatism then bestirred
themselves and the bill was held up. Forseeing a movement of
the same kind in this country, the American Manufactures'
Association got busy, laid plans to defeat such movement which
they later did. Strictly speaking this action was not taken by
the association as such but only by a part of it. One fourth of
the membership and probably much more than a fourth of the
capital of the association was on the side for the adoption of
the system. Politically, however, the side opposed to the new
system had altogether the most influence.

Careful study of the whole matter showed that the main cost to
make the change to the new system would be in dies, patterns,
gauges, jigs, etc. A careful estimate put this cost at $600 for
each workman and assuming a million workmen, we have a total
cost of $600,000,000. But we have just seen that the annual
expense of retaining the old system of weights and measures is
over $300,000,000. Thus we see that two short years would
suffice to pay for what seems to the great manufacturers
association an insuperable expense. From all this we see that
the question is not one for N. M. A. bookkeeping, but for
national bookkeeping.

Many well-informed people studying the matter superficially,
think the difficulties in the way of a change to the new system
insurmountable. Thus, they think of the cost to the
manufacturer--which we have just seen to be rather large but
not insurmountable; they think of the changes needed in books,
records, such as deeds, and the substitution of new measuring
and weighing instruments. Germany and all the other countries
of continental Europe made the change. Are we to assume that
the United States can not? That would be ridiculous. Granting
that commerce has grown greatly, so also has intelligence and
capability of the people for doing great things.

Scientists are universally agreed as to the wisdom of the
adoption of the metric system. The country, as a whole, must be
educated up to the notion that sooner or later it is sure to be
universally adopted, that it is only a question of time when
this will be done. Already electrical, chemical and optical
manufacturing concerns use the metric units and system
exclusively. The system is also used widely in medicine and
still other arts. Then all institutions of learning use the
metric system exclusively whenever this is possible. All that
is needed is to complete a good work well begun.

There is one rational objection to the metric system and but
one. It is that 10 is inferior to 12 as a base for a notation
for numbers, but the world is not ready to make this change nor
is it likely to be for generations to come. Moreover, this
improvement is far less important than uniformity in weights
and measures. For these reasons this objection can be passed
over. Men said the metric system would never be used outside of
France; but it has come to be used all over the world. The
prophets said we should never have uniformity as regards a
reference meridian of longitude. But we have. And so it will be
with the adoption of the metric system in the United States and
Great Britain. It is only a question of whether it comes sooner
or later. When that day comes, the meter, a long yard, will
replace the yard, the liter, the quart (being smaller than a
dry and larger than a liquid quart), the kilogram will replace
the pound, being equal to 2.2 pounds, and the kilometer (.6
mi.) will replace the mile. Within a week or so after the
change has been made to the new system, all men in business
will be reasonably familiar with the new units and how they are
used, and within a few months every man, woman and child will
be as familiar with the new system as they ever were with the
simplest parts of the old. So easy it will be to make the
change as far as ordinary business affairs are concerned.
However, for exact metal manufactures years will be needed to
fully change over to the new. Here the plan is to begin with
new unit constructions and new models, as automobiles using new
machinery constructed in the integral units of the metric
system. All old constructions are left as they are and repaired
as they are. This was the plan used in Germany and of course it
works.

In conclusion it can be said that we started with the idea that
the change to the metric system was needed for the sake of
foreign commerce. We now see that we need it also for our own
commercial and manufacturing transactions. If we are to have
the efficiency so insistently demanded by the age in which we
live, then we must have the metric system in use for the
ordinary affairs of daily life of the masses of the people, we
must have it in commercial and manufacturing industries, and we
must have it in education. If efficiency is to be the slogan,
then the metric system must come no matter what obstacles stand
in its way.



ADAPTATION AS A PROCESS

BY PROFESSOR HARRY BEAL TORREY

REED COLLEGE

FOR the physicist and chemist the term adaptation awakens but
the barren echo of an idea. In biology it still retains a
certain standing, though its significance has, in recent years,
been rapidly contracting, as the influence of the conception
for which it stands has waned. Many biologists are now of the
opinion that their science would be better off entirely without
it. They believe it has not only outlived its usefulness, but
has become a source of confusion, if not, indeed, reaction.

Darwin's first task, in the "Origin of Species," was to
demonstrate that species had not been independently created,
but had descended, like varieties, from other species. But he
was well aware that

such a conclusion, even if well founded, would be
unsatisfactory until it could be shown how the innumerable
species inhabiting the world have been modified, so as to
acquire that perfection of structure and coadaptation which
justly excites our admiration.

To establish convincingly the doctrine of descent with
modification as a theory of species, it was necessary for him
to develop the theory of adaptation which we now know as
natural selection.

The origin of adaptive variations gave him, at that time,
little concern. Though keenly appreciative of the problem of
variation which his studies in evolution presented, he
dismissed it in the "Origin" with less than twenty-five pages
of discussion. Such brevity is not surprising, since a more
extended treatment would only have embarrassed the progress of
the argument. In fact, his restraint in this direction enabled
him, first, to avoid the difficulties into which Lamarck, with
his bold attack on the problem of variation, had fallen; and
second, by doing so, to deal the doctrine of Design a blow from
which it has never recovered.

The latter was a service of well-nigh incalculable value to the
young science of biology--and, as it appeared, to modern
civilization as well. But it has not been uncommon, from
Aristotle's day to this, for the work of great men to suffer at
the hands of less imaginative followers. Sweeping applications
of Darwin's doctrine have been repeatedly made without due
regard either for its original object or for the success with
which that object was achieved. So I believe it to be no fault
of Darwin that the growing indifference of European
laboratories toward natural selection should find occasional
expression in such a phrase as "the English disease." Disease,
indeed, I believe we must in candor admit that devotion to it
to be which blinds its devotees to those problems of more
elementary importance than the problem of adaptation, which
Darwin clearly saw but was born too soon to solve.

The problem of species has profoundly changed since 1859. For
Darwin it was perforce a problem of adaptation. For the
investigator of to-day it has become a part of the more
inclusive problem of variation. Along with the logical results
of natural selection he contemplates the biological processes
of organic differentiation. He is no longer satisfied to assume
the existence of those modifications that make selection
possible. In his efforts to control them, the conception of
adaptation as a result has been crowded from the center of his
interest by the conception of adaptation as a process.

The survival of specially endowed organisms, the elimination of
competing individuals not thus endowed, are facts that possess,
in themselves, no immediate biological significance. Selection
as such is not a biological process, whether it is accomplished
automatically on the basis of protective coloration, or
self-consciously by man. Separating sheep from goats may have a
purely commercial interest, as when prunes and apples, gravel
and bullets, are graded for the market. Such selection is, at
bottom, a method of classification, serving the same general
purpose as boxes in a post-office. Similarly, natural selection
is but a name for the segregation and classification that take
place automatically in the great struggle for existence in
nature. The fact that it is a result rather than a process
accounts, probably more than anything else, for its remarkable
effect upon modern thought. It is non-energetic. It exerts no
creative force. As a conception of passive mechanical
segregation and survival, it was a most timely and potent
substitute for the naive teleology involved in the idea of
special creation.

As a theory of adaptation, then, natural selection is
satisfactory only in so far as it accounts for the
"preservation of favored races." It throws no light upon the
origin of the variations with which races are favored. Since it
is only as variations possess a certain utility for the
organism that they become known as adaptations, the conception
of adaptation is inevitably associated with the welfare of
individuals or the survival of races. To disregard this
association is to rob the conception of all meaning. Like
health, it has no elementary physiological significance.

Our profound interest in the problem of survival is natural and
practical and inevitable. But in spite of Darwin's great
contribution toward a scientific analysis of the mechanism of
organic evolution, and in spite of the marvelous recent
progress of medicine along its many branches, the fact remains
that so far as this interest in the problem of survival is
dominant it must continue to hinder adequate analysis of the
problem of adaptation. Indeed, it is in large measure due to
such domination in the past that biology now lags so far behind
the less personal sciences of physics and chemistry. For
survival means the survival of an individual. And there is no
doubt that the individual organism is the most conspicuous
datum in the living world. The few who, neglectful of
individuals and survivals, find their chief interest in living
substance, its properties and processes, are promptly
challenged by the many to find living substance save in the
body of an organism. Thus, in a peculiarly significant sense,
organisms are vital units. And since the individual organism
shows a remarkable capacity to retain its identity under a wide
range of conditions, adaptability or adjustability comes to be
reckoned as the prime characteristic of life by all to whom the
integrity of the individual organism is the fact of chief
importance.

With the use of the words adaptability and adjustability, our
discussion assumes a somewhat different aspect. Instead of
contemplating further the mechanical selection of individuals
on the basis of characters that, like the structure of "the
woodpecker, with its feet, tail, beak and tongue, so admirably
adapted to catch insects under the bark of trees," can not be
attributed to the influence of the external conditions that
render them useful, we are invited to consider immediate and
plastic adjustments of the organism to the very conditions that
call forth the response. For the fortuitous adjustments that
tend to preserve those individuals or races that chance to
possess them, are substituted, accordingly, the direct primary
adjustments that tend to preserve the identity of the reacting
organism. We turn thus from the RESULTS of the selection of
favorable variations to the biological PROCESSES by which
organisms become accommodated to their conditions of life.

At once the old questions arise. Are these processes
fundamentally peculiar to the life of organisms? Does the
capacity of the organism thus to adjust itself to its
environment involve factors not found in the operations of
inorganic nature? Our answers will be determined essentially by
the nature of our interest in the organism--whether we regard
its existence as the END or merely an incidental EFFECT of its
activities. The first alternative is compatible with
thoroughgoing vitalism. The second, emphasizing the nature of
the processes rather than their usefulness to the organism,
relieves biology of the embarrassments of vitalistic
speculation, and allies it at the same time more intimately
than ever with physics and chemistry. This alliance promises so
well for the analysis of adaptations, as to demand our serious
attention.

Physiologically, the living organism may be thought of as a
physico-chemical system of great complexity and peculiar
composition which varies from organism to organism and from
part to part. Life itself may be defined as a group of
characteristic activities dependent upon the transformations in
this system under appropriate conditions. According to this
definition, life is determined not only by the physical and
chemical attributes of the system, but by the fitness of its
environment, which Henderson has recently done the important
service of emphasizing.[1] Relatively trifling changes in the
environment suffice to render it unfit, however, that is, to
modify it beyond the limits of an organism's adaptability. The
environmental limits are narrow, then, within which the
transformations of the organic system can take place that are
associated with adaptive reactions. The conditions within these
limits are, further, peculiarly favorable for just such
transformations in just such physico-chemical systems.

[1] "The Fitness of the Environment."



The essential characteristic of the adaptive reaction appears
to be that the organism concerned responds to changing
conditions without losing certain attributes of behavior by
which we recognize organisms in general and by which that
organism is recognized in particular. It exhibits stability in
the midst of change; it retains its identity. But this
stability, let us repeat, is the stability of a certain type of
physico-chemical system, with respect to certain characters
only, and exhibited under certain circumscribed conditions. In
so far as the problem of adaptation is thus restricted in its
application, it remains a question of standards, a taxonomic
convenience, a problem of the organism by definition only,
empty of fundamental significance.

It is to be expected that systems differing widely in
composition and structure will differ in their responses to
given conditions. This will be true whether the systems
compared thus are organic, or inorganic, or representative of
both groups. The compounds of carbon, of which living substance
is so characteristically composed, exhibit properties and
reactions that distinguish them at once in many respects from
the compounds of lead or sulphur. They also differ widely among
themselves; compare, in this connection, serum albumen, acetic
acid, cane sugar, urea. No vitalistic factor is needed for the
interpretation of divergencies of this kind. But there are many
significant similarities between organisms and inorganic
systems as well. These are so frequently overlooked that it
will now be desirable to consider a few illustrative cases. For
the sake of brevity, they have been selected as representative
of but two types of adaptation commonly known under the names
of ACCLIMATIZATION and REGULATION.

Let us first consider the case of organisms which become
acclimatized by slow degrees to new conditions that, suddenly
imposed, would produce fatal results. Hydra is an organism
which becomes thus acclimatized finally to solutions of
strychnine too strong to be endured at first. Outwardly it
appears to suffer in the process no obvious modifications. Yet
modifications of a physiological order take place, as is shown,
first, by the necessary deliberation of the acclimatization,
second, by the death of the organism if transferred abruptly
back to its original environment.

In other forms the structural changes accompanying
acclimatization may be far more conspicuous. For example, the
aerial leaves of Limnophila heterophylla are dentate, while
those grown under water are excessively divided. Again, the
helmets and caudal spines of Hyalodaphnia vary greatly in
length with the seasonal temperature.

In these and the large number of similar cases that might be
cited, stability of the physiological system under changed
conditions is only obtained by changes in the system itself
which are often exhibited by striking structural modifications.

Compare with such phenomena of acclimatization the responses of
sulphur, tin, liquid crystals and iron alloys to changes of
temperature. The rhombic crystals that characterize sulphur at
ordinary temperatures and pressures, give place to monoclinic
crystals at 95.5 degrees C. Sulphur thus exists with two
crystalline forms whose stability depends directly upon the
temperature.

Similarly, tin exists under two stable forms, white and gray,
the one above, the other below the transitional point, which
is, in this case, 18 degrees C. At this temperature white tin
is in a metastable condition, and transforms into the gray
variety. The transformation goes on, then, at ordinary
temperatures, but, fortunately for us as users of tin
implements, very slowly. Its velocity can be increased,
however, by lowering the temperature, on which, then, not only
the transformation itself, but its rate depends.

In this connection may be mentioned cholesteryl acetate and
benzoate and other substances which possess two crystalline
phases, one of which is liquid, unlike other liquids, however,
in being anisotropic. As in the preceding cases, these phases
are expressions of equilibrium at different temperatures.

Especially instructive facts are afforded by the alloys of iron
and carbon. Iron, or ferrite, exists under three forms: as
alpha ferrite below 760 degrees, as beta ferrite between 760
degrees and 900 degrees, and as gamma ferrite above 900
degrees. Only the last is able to hold carbon in solid
solution. The alloys of iron and carbon exist under several
forms. Pearlite is a heterogeneous mixture containing 0.8 per
cent. carbon. When heated to 670 degrees, it becomes
homogeneous, an amount of carbon up to two per cent. dissolves
in the iron, and hard steel or martensite is formed. In
appearance, however, the two forms are so nearly identical as
to be discriminated only by careful microscopical examination.
Cementite is a definite compound of iron and carbon represented
by the formula Fe<3 subscript>C.

When cooled slowly below 670 degrees, martensite yields a
heterogeneous mixture of pearlite and ferrite (or cementite, if
the original mixture contained between 0.8 per cent. and two
per cent. of carbon). Soft steels and wrought iron are thus
obtained. When cooled rapidly, however, as in the tempering of
steel, martensite remains a homogeneous solid solution, or hard
steel.

One can not fail to notice the remarkable parallel between
these facts and the behavior of Hydra in the presence of
strychnine. In both cases new positions of stability are
reached by modifying the original conditions of stability; and
in both, the old positions of stability are regained only by
returns to the original conditions of stability so gradual as
to afford time sufficient for the necessary transformations in
the systems themselves.

The forms which both organic and inorganic systems assume thus
appear to be functions of the conditions in which they exist.

The fact that Hydra is able to regain a position of stability
from which it had been displaced connects the behavior of this
organism not only with the physical phenomena already cited,
but still more intimately with the large class of chemical
reactions which are similarly characterized by equilibrium and
reversibility. Such reactions do not proceed to completion,
which is probably always the case wherever the mixture of the
systems under transformation is homogeneous, as in the case of
solutions. They occur widely among carbon compounds. The
following typical case will suffice to indicate their essential
characteristics.

When ethyl alcohol and acetic acid are mixed, a reaction ensues
which yields ethyl acetate and water. But ethyl acetate and
water react together also, yielding ethyl alcohol and acetic
acid. This second reaction, in a direction opposite to the
first, proceeds in the beginning more slowly also. There comes
a time, however, when the speeds of the two reactions are
equal. A position of equilibrium or apparent rest is thus
reached, which persists as long as the relative proportions of
the component substances remain unchanged.

A great many reversible reactions are made possible by enzymes.
In the presence of diastase, glucose yields glycogen and water,
which, reacting together in the opposite direction, yield
glucose again. In the presence of emulsin, amygdalin is
decomposed into glucose, hydrocyanic acid and benzoic aldehyde,
and reformed from them. Similarly in the presence of lipase,
esters are reformed from alcohols and fatty acids, their
decomposition products.

With the introduction of enzymes, certain complications ensue.
Though it has been shown that lipase acts as a true catalyser,
this may not hold for all, especially for proteolytic, enzymes.
That reversible reactions actually occur in proteids, however,
accompanied as they are in some cases at least by certain
displacements of the position of equilibrium, there appears to
be no question.[2]

[2] Robertson, Univ. Calif. Publ. Physiol., 3, 1909, p. 115.



These examples are but suggestions of the many reversible
reactions that have now been observed among the compounds of
carbon. That they have peculiar significance for the present
discussion resides in the fact that living substance is
composed of carbon compounds, so many and in such exceedingly
complex relations as to present endless possibilities for
shifting equilibria and the physical and chemical adjustments
resulting therefrom.

With these facts in mind we may now turn from the consideration
of acclimatization to a brief discussion of certain phenomena
of regulation--adaptive reactions that are especially
conspicuous in the growth and development of organisms, but
separated by no sharp dividing line from adaptive reactions of
the other type.

When a fragment of an organism transforms, under appropriate
conditions, into a typical individual, the process includes
degenerative aa well as regenerative phases. There is always
some simplification of the structures present, whose character
and amount is determined by the degree of specialization which
has been attained. The smaller the piece, within certain
limits, and the younger physiologically, the more nearly does
it return to embryonic conditions, a fact which can be studied
admirably in the hydroid Corymorpha. In some cases the
simplification is accomplished by abrupt sacrifice of highly
specialized parts, as in Corymorpha, when in a process of
simplification connected with acclimatization to aquarium
conditions, the large tentacles of well-grown specimens fall
away completely from their bases. In other hydroids (e. g.,
Campanularia) the tentacles may be completely absorbed into the
body of the hydranth from which they originally sprang. Among
tissue cells degenerative changes may be abrupt, as in the
sacrifice of the highly specialized fibrillae in muscle cells;
or they may be very gradual, as in the transformation of cells
of one sort into another that occurs in the regeneration of
tentacles in Tubularia.

An interesting case of absorption of parts came to my notice
while studying the larvae of the pennatulid coral Renilla some
fifteen years ago. As will be remembered, Renilla possesses
eight tentacles with numerous processes pinnately arranged.
During a period of enforced starvation, these pinnae were
gradually absorbed, and the tentacles shortened, from tip to
base. With the advent of food--in the form of annelid eggs--the
reverse of these events took place. The tentacles lengthened
and the pinnae reappeared, the larvae assuming their normal
aspect.

It appears, then, that in some circumstances at least, the
process of simplification may resemble very nearly, even in
details, a reversal of the process of differentiation. That one
is actually in every respect the reverse of the other is
undoubtedly not true. This, however, is not to be wondered at.
Mechanical inhibitions that are so conspicuous in some cases
(e. g., Corymorpha) are to be expected to a certain degree in
all. The regenerative process itself depends upon the
cooperation of many physical and chemical factors, in many and
complex physicochemical systems in varying conditions of
equilibrium. And it is important to note that even the
equilibrium reactions by which a single proteid in the presence
of an enzyme, is made and unmade, do not appear always to
follow identically the same path in opposite directions.[3]

[3] Robertson, vid. sup., p. 269.



Whatever their course in the instances cited and in many
others, reversals in the processes of development do take
place. In perhaps their simplest form these can be seen in egg
cells. The development of a fragment of an egg as a complete
whole involves reversals in the processes of differentiation of
a very subtle order. The fusion of two eggs to one involves
similar readjustments. Such phenomena have been held to be
peculiar to living machines only. Yet it may be pointed out
that there are counterparts of both in the behavior of
so-called liquid crystals. When liquid crystals of
paraazoxyzimtsaure-Athylester are divided, the parts are
smaller in size, but otherwise identical with the parent
crystal in form, structure and optical properties. The fusion
of two crystals of ammonium oleate forming a single crystal of
larger size has also been observed. Though changes in
equilibrium that accompany such behavior of liquid crystals are
undoubtedly very much simpler than the changes that accompany
the regulatory processes exhibited by the living egg, the
striking resemblance between the phenomena themselves tempts us
not to magnify the difference.

Further temptation in the same direction is offered by the
recent discovery[4] that the processes of development
stimulated in the eggs of the sea urchin Arbacia by butyric
acid or weak bases, and evidenced by the formation of the
fertilization membrane, is reversible. When such eggs are
treated with a weak solution of sodium cyanide or chloral
hydrate, they return to the resting condition. Upon
fertilization with spermatozoa, in normal sea water, they
proceed again to develop.

The facts that have now been briefly summarized have been
selected to emphasize the growing intimacy between the
biological and the inorganic sciences. No harm can conceivably
come from it. On the contrary, there is every reason to be
hopeful that the investigation of biological problems in the
impersonal spirit that has long distinguished the maturer
sciences of physics and chemistry will continue to develop a
better control and fuller understanding of the processes in
living organisms, of which the phenomena of variation in
general, and of adaptation in particular, are but incidental
effects.



WHY CERTAIN PLANTS ARE ACRID

BY PROFESSOR WILLIAM B. LAZENBY

OHIO STATE UNIVERSITY

EVER since my first lessons in botany, the characteristic
qualities and properties of plants have given me much thought.
Why certain plants produced aromatic oils and ethers, while
others growing under the same conditions produced special acids
or alkaloids, was a subject of endless speculation.

The pleasing aroma of the bark of various trees and shrubs, the
spicy qualities of the foliage and seeds of other plants; the
intense acridity; the bitterness; the narcotic, the poisonous
principle in woody and herbaceous species; all were intensely
interesting.

This interest was biological rather than chemical. I cared less
for the ultimate composition of the oils, acids, alkalis, etc.,
than I did for their use or office in the plant economy, and
their effect upon those who might use them.

Perhaps no one plant interested me more from this point of
view, than the well-known Indian turnip (Arisoema triphyllum).
As a boy I was well acquainted with the signally acrid quality
of this plant; I was well aware of its effect when chewed, yet
I was irresistibly drawn to taste it again and again. It was
ever a painful experience, and I suffered the full penalty of
my rashness. As an awn from a bearded head of barley will win
its disputed way up one's sleeve, and gain a point in advance
despite all effort to stop or expel it, so did every
resolution, every reflection, counteract the very purpose it
was summoned to oppose, and to my sorrow I would taste the
drastic, turnip-shaped corm wherever opportunity occurred.

It is a well-known fact that the liquid content of the cells of
plants contain numerous inorganic substances in solution. Among
these, not considering oxygen, hydrogen, nitrogen and carbon
dioxide, there are the salts of calcium, magnesium, potassium,
iron, sulphur and phosphorus. The above substances are found in
the cells of every living plant. Other substances like salts of
sodium and silica are also found, but these are not regarded as
essential to the life and growth of plants. They appear to be
present because the plant has not the power to reject them.
Many of the substances named above, are found deposited either
in an amorphous or crystalline form in the substance of the
cell wall. In addition to this, crystals of mineral matter,
having various shapes and sizes, are often found in the
interior of cells. The most common of these interior cell
crystals are those composed of calcium oxalate and calcium
carbonate. Others composed of calcium phosphate, calcium
sulphate and silica are sometimes found. These crystals may
occur singly or in clusters of greater or less size. In shape
they are prismatic or needle-like.

It is not the object of this paper to treat of plant crystals
in general, but to consider the peculiar effect produced by
certain forms when found in some well-known plants.

The extreme acridity or intense pungency of the bulbs, stems,
leaves and fruit of various species of the Araceae or Arum
family, was recognized centuries ago. The cause of this
characteristic property or quality was, until a comparatively
recent date, not definitely determined.

As far as I am aware the first scientific investigation of this
subject was made by the writer. At a meeting of the American
Association for the Advancement of Science held at Indianapolis
in 1890, some studies and experiments were reported in a short
paper entitled "Notes upon the Crystals in certain species of
the Arum Family."

This paper expressed the belief that the acridity of the Indian
turnip and other plants belonging to the same family, was due
to the presence of needle-shaped crystals or raphides found in
the cells of these plants. This conclusion was not accepted by
Professor T. J. Burrill, of the University of Illinois, nor by
other eminent botanists who were present and took part in the
discussion that followed the reading of the paper.

The opposition was based mainly on the well-known fact that
many other plants like the grape, rhubarb, fuchsia, spiderwort,
etc., are not at all, or but slightly acrid, although the
raphides are as abundant in them as in the Indian turnip and
its allies.

Up to this time the United States Dispensatory and other works
on pharmacy, ascribed the following rather indefinite cause for
the acridity of the Indian turnip. It was said to be due to an
acrid, extremely volatile principle. This principle was
insoluble in water and alcohol, but soluble in ether. It was
dissipated both by heating and drying, and by this means the
acridity is destroyed. There was no opinion given as to the
real nature of this so-called principle.

More recently it has been intimated that the acridity may be
due to some ferment or enzyme, which has been derived in part
from the self-decomposition of protoplasm and in part by the
process of oxidation and reduction.

Here the question appeared to rest. At all events I was unable
to glean any further knowledge from the sources at my command.

Some time later the subject was taken up in a more
comprehensive manner and the following report is the first
detailed description of an investigation that has occupied more
or less of my leisure for some years.

A dozen or more species of plants have been used for
examination and study. Among these were:

Indian turnip (Arisoema triphyllum).
Green dragon (Arisoema dracontium).
Sweet-flag (Acorus).
Skunk cabbage (Spathyema).
Calla (Richardia).
Caladium (Caladium).
Calocasia (Calocasia).
Phyllodendron (Phyllodendron).
Fuchsia (Fuchsia).
Wandering Jew (Tradescantia).
Rhubarb (Rheum).
Grape (Vitis).
Onion (Allium).
Horse-radish (Armoracia).

Most of the plants selected were known to have crystals in
certain parts. Some of them were known to be intensely acrid.
In these the acridity was in every instance proportional to the
number of crystals.

The following order of study was pursued and the results of
each step noted. Only the more salient points of the methods
employed and the conclusions reached are presented.

1. The Character of the Taste Itself.--It was readily noted
that the sensation produced by chewing the various acrid plants
was quite different. For example, the Indian turnip and its
close allies do not give the immediate taste or effect that
follows a similar testing of the onion or horse-radish. When
the acridity of the former is perceived the sensation is more
prickling than acrid.

The effect produced is more like the pricking of numerous
needles. It is felt not only upon the tongue and palate, but
wherever the part tasted comes into contact with the lips, roof
of mouth or any delicate membrane. It is not perceived where
this contact does not occur.

The acridity of the onion and horse-radish is perceived at once
and often affects other parts than those with which it comes
into direct contact.

2. The Acrid Principle Is Not Always Volatile.--This is shown
by the fact that large quantities of the mashed or finely
grated corms of the Indian turnip and allied species, produced
no irritation of the eyes or nose even when these organs were
brought into close contact with the freshly pulverized
material. This certainly is in marked contrast with the effect
produced by freshly grated horse-radish, peeled onions, crushed
mustard seed when the same test is applied.

It seems fair to assume that in the latter case some principle
that is volatile at ordinary air temperatures is present. The
assumption that such principle is present in the former has no
room.

In order to test this matter further a considerable quantity of
the juice of the Indian turnip was subjected to careful
distillation, with the result that no volatile principle or
substance of any kind was found.

Various extractive processes were tried by using hot and cold
water; alcohol, chloroform, benzene, etc. These failed in every
instance to remove any substance that had a taste or effect
anything like that found in the fresh Indian turnip.

3. The Acrid Principle Is Not Soluble in Ether.--Inasmuch as
various works on pharmacy made the claim that the active or
acrid principle of the plants in question was soluble in ether,
this was the next subject for investigation. The juice was
expressed from a considerable quantity of the mashed Indian
turnip. This juice was clear and by test was found to possess
the same acrid property as the unmashed corms.

Some of the juice and an equal quantity of ether were placed
into a cylinder and well shaken. After waiting until the ether
had separated a few drops of the liquid were put into the
mouth. For a little time no result was perceived, but as soon
as the effect of the ether had passed away the same painful
acridity was manifest as was experienced before the treatment
with the ether. A natural conclusion from this test was that
the acridity might come from some principle soluble in ether.

Observing that the ether was quite turbid and wishing to learn
the cause, a drop or two was allowed to evaporate on a glass
slide. Examining the residue with a microscope it was found to
consist of innumerable raphides or needle-like crystals. Some
of the ether was then run through a filter. The filtrate was
clear. An examination showed it to be entirely free from
raphides, and it had lost every trace of its acridity. The
untreated acrid juice of the Indian turnip, calla, and other
plants of the same family was then filtered and in every
instance the filtered juice was bland and had lost every trace
of its acridity. These tests and others that need not be
mentioned, proved conclusively that the acridity of various
species of the Arum family was not due to a volatile principle,
but was due to the needle-shaped crystals found so abundantly
in these plants.

Several questions yet remained to be answered. (1) If these
needle-like crystals or raphides are the cause of the acridity
of the plants just mentioned, why do they not produce the same
effect in the fuchsia, tradescantia and other plants where they
are known to be just as abundant? (2) Why does the Indian
turnip lose its acridity on being heated? (3) Why does the
dried Indian turnip lose its acridity?

It was first thought that the raphides found in plants having
no acridity, might be of different chemical composition than
those which produce this effect.

A chemical examination proved beyond question that the raphides
were of the same composition. The needle-shaped crystals in all
the plants selected for study were composed of calcium oxalate.
The crystals, found in grape, rhubarb, fuchsia and tradescantia
were identical in form, fineness and chemical composition with
those found in the plants of the Arum family. How then account
for the painfully striking effect in one case and the
non-effect in the other? This was the perplexing question.

In expressing some juice from the stems and leaves of the
fuchsia and tradescantia it was found to be quite unlike that
of the Indian turnip and calla. The juice of the latter was
clear and limpid; that of the former quite thick and
mucilaginous. There was no difference as to the abundance of
crystals revealed by the microscope.

After diluting the ropy, mucilaginous juice with water, and
shaking it thoroughly with an equal volume of ether, there was
no turbidity seen in the supernatent ether. Allowing a few
drops of the ether to evaporate scarcely any crystals could be
found. Practically none of them had been removed from the
insoluble mucilaginous covering. Here and there an isolated
specimen was all that could be seen. So closely were these
small crystals enveloped with the mucilaginous matter that it
was almost impossible to separate or dissect them from it.

It was now easy to explain why certain plants whose cells were
crowded with raphides were bland to the taste, while other
plants with the same crystals were extremely acrid.

In one case the crystals were neither covered nor embedded in
an insoluble mucilage, but were free to move. Thus when the
plant was chewed or tasted the sharp points of these
needle-like crystals came into contact with the tongue, lips
and membranous surface of the mouth.

In the other case the insoluble mucilage which surrounded the
crystals prevented all free movement and they produced no
irritation.

Why do these intensely acrid, aroid plants lose their acridity
on being heated? It is well known that the corms of the Indian
turnip and its allies contain a large amount of starch. In
subjecting this starch to heat it becomes paste-like in
character. This starch paste acts in the same manner as the
insoluble mucilage. It prevents the free movement of the
crystals and in this way all irritant action is precluded. In
heating the Indian turnip and other corms, it was found that
the heat applied must be sufficient to change the character of
the starch or the so-called acridity was not destroyed.

One other question remains to be answered. It has long been
noted that the old or thoroughly dried corms of the Indian
turnip are not acrid like those that are fresh. The explanation
is simple. As the plant dries or loses its moisture, the walls
of the cells collapse and the crystals are closely encased in
the hard, rigid matter that surrounds them. This prevents free
movement and the crystals can not exert any irritant action.

It is generally believed by biologists that the milky juice,
aromatic compounds, alkaloids, etc., found in plants have no
direct use in the economy of the plant. They are not connected
with the nutritive processes. They are excretions or waste
products that the plant has little or no power to throw off.
There can be little doubt, however, that these excretory
substances often serve as a means of protection. Entomologists
have frequently stated that the milky juice and resins found in
the stems of various plants act as a protection against stem
boring insects. In like manner the bulbs, stems and leaves of
plants that are crowded with crystals have a greater immunity
from injurious biting insects than plants that are free from
crystals. It is quite generally believed that the formation of
crystals is a means of eliminating injurious substances from
the living part of the plant. These substances may be regarded
as remotely analogous to those organic products made by man in
the chemical laboratory.

Some progress has been made in this direction, but so far the
main results are certain degradation-products such as aniline
dyes derived from coal tar; salicylic acid; essences of fruits;
etc. Still these and many other discoveries of the same nature
do not prove that the laboratory of man can compete with the
laboratory of the living plant cell.

Man has the power to break down and simplify complex substances
and by so doing produce useful products that will serve his
purposes. We may combine and re-combine but so far we only
replace more complex by simpler combinations.

The plant alone through its individual cells, and by its living
protoplasm has fundamentally creative power. It can build up
and restore better than it can eliminate waste products.



HOW OUR ANCESTORS WERE CURED

BY PROFESSOR CARL HOLLIDAY

UNIVERSITY OF MONTANA

SUPPOSE you had a bad case of rheumatism, and your physician
came to your bedside and exclaimed loudly, "Hocus pocus, toutus
talonteus, vade celeriter jubeo! You are cured." What would you
think, what would you do, and what fee would you pay him?
Probably, in spite of your aches and pangs, you would make
astonishing speed--for a rheumatic person--in proffering him
the entire room to himself. But there was a time--and that as
late as Shakespeare's day--when so-called doctors in rural
England used just such words not only for rheumatism, but for
many another disease. And to this hour the fakir on the street
corner uses that opening expression, "Hocus pocus." Those words
simply prove how slowly the Christian religion was absorbed by
ancient Anglo-Saxon paganism; for "Hocus pocus" is but the
hastily mumbled syllables of the Catholic priest to his early
English congregation--"Hoc est corpus," "this is the body"; and
the whole expression used by the old-time doctor meant merely
that in the name of the body of Christ he commanded the disease
to depart quickly.

How superstitions and ancient rites do persist. To this hour
the mountaineers of southwestern Virginia and eastern Tennessee
believe that an iron ring on the third finger of the left hand
will drive away rheumatism, and to my personal knowledge one
fairly intelligent Virginian believed this so devoutly that he
actually never suffered with rheumatic pains unless he took off
the iron ring he had worn for fifteen years. It is an old, old
idea--this faith in the ring-finger. The Egyptians believed
that a nerve led straight from it to the heart; the Greeks and
Romans held that a blood-vessel called the "vein of love"
connected it closely with that organ; and the medieval
alchemists always stirred their dangerous mixtures with that
finger because, in their belief, it would most quickly indicate
the presence of poison. So, too, many an ancient declared that
whenever the ring-finger of a sufferer became numb, death was
near at hand. Thus in twentieth century civilization we hear
echoes of the life that Rameses knew when the Pyramids were
building.

Our Anglo-Saxon forefathers had great faith in mysterious
words. The less they understood these the more they believed in
the curative power. Thus the name of foreign idols and gods
brought terror to the local demons that enter one's body, and
when Christianity first entered England, and its meanings were
but dimly understood, the names of saints, apostles and even
the Latin and Greek forms of "God" and "Jesus" were enemies to
all germs. Then, too, what comfort a jumbling of many languages
brought to the patient, especially if the polyglot cure were
expressed in rhythmic lines. Here, for instance, in at least
five languages, is a twelfth century cure for gout:

Meu, treu, mor, phor,
Teux, za, zor,
Phe, lou, chri
Ge, ze, on.

Perhaps to our forefathers suffering from over-indulgence in
the good things of this world, this wondrous group of sounds
brought more comfort than the nauseous drugs of the modern
practitioner. Any mysterious figure or letter was exceedingly
helpful in the sick room of a thousand years ago. The Greek
letters "Alpha" and "Omega" had reached England almost as soon
as Christianity had, and the old-time doctor triumphantly used
them in his pow-wows. Geometric figures in a handful of sand or
seeds would prophesy the fate of the ills--and do we not to
this day tell our fortune in the geometric figures made by the
dregs in our tea-cups? Paternosters, snatches of Latin hymns,
bits of early Church ritual were used by quacks of the olden
days for much the same reason as the geometric figures--because
they were unusual and little understood.

It would have been well had our Anglo-Saxon forefathers
confined their healing practices to such gentle homeopathic
methods as those mentioned above; but instead desperate
remedies were sometimes administered by the determined
medicine-man. Diseases were supposed to be caused mainly by
demons--probably the ancestors of our present germs--and the
physician of Saxon days used all the power of flattery and
threat to induce the little monsters to come forth. When the
cattle became ill, for instance, the old-time veterinarian
shrieked, "Fever, depart; 917,000 angels will pursue you!" If
the obstinate cow refused to be cured by such a mild threat,
the demons were sometimes whipped out of her, and, if this
failed to restore her health, a hole was pierced in her left
ear, and her back was struck with a heavy stick until the evil
one was compelled to flee through the hole in her ear. Nor was
such treatment confined to cattle. The muscular doctors of a
thousand years ago claimed they could cure insanity by laying
it on lustily with a porpoise-skin whip, or by putting the
maniac in a closed room and smoking out the pestering fiends.
One did well to retain one's sanity in those good old days.

This use of violent words or deeds in the cure of disease is as
ancient almost as the race of man. The early Germans attempted
to relieve sprains by reciting confidently how Baldur's horse
had been cured by Woden after all the other mighty inhabitants
of Valhalla had given up the task, and even earlier tribes of
Europe and Asia had used for illness such a formula as: "The
great mill stone that is India's is the bruiser of every worm.
With that I mash together the worms as grain with a mill
stone." Long after Christianity had reached the Anglo- Saxons
of England, the sick often hung around their necks an image of
Thor's hammer to frighten away the demon germs that sought to
destroy the body. This appeal to a superior being was common to
all Indo-European races, and the early Christian missionaries
wisely did not attempt to stamp out a belief of such antiquity,
but merely substituted the names of Christ, the Virgin Mary and
the saints for those of the heathen deities. And even into the
nineteenth century this ancient form of faith cure persisted;
for there are living yet in Cornwall people who heard, as
children, this charm for tooth-ache:

 Christ passed by his brother's door,
Saw his brother lying on the floor;
What aileth thee, brother!
Pain in the teeth.
Thy teeth shall pain thee no more,
In the name of the Father, Son and Holy Ghost,
I command the pain to be gone.

Let us no longer boast of the carefulness of the modern
physician; the ceremonies and directions of the Anglo-Saxon
doctor were just as painstaking in minuteness and accuracy.
When you feel the evil spirits entering you, immediately seek
shelter under a linden tree; for out of linden wood were not
battle-shields made? Long before Christianity had brought its
gentler touches to English life the tribal medicine man wildly
brandished such a shield, and sang defiantly to the witch
maidens or disease demons:

Loud were they, lo! loud, as over the land they rode;
Fierce of heart were they, as over the hill they rode;
Shield thee now thyself, from their spite thou may'st escape
thee.
Out, little spear, if herein thou be!
Underneath the linden stand I, underneath the shining shield,
For the might maidens have mustered up their strength,
And have sent their spear screaming through the air!
Back again to them will I send another,
Arrow forth a-flying from the front against them!
Out, little spear, if herein thou be!

This business of singing was very necessary in the old time
doctor's practice. Sometimes he chanted into the patient's left
ear, sometimes into his mouth, and sometimes on some particular
finger, and the patient evidently had to get well or die to
escape the persistent concerts of his physician. Not
infrequently, too, the doctor placed a cross upon the part of
one's anatomy to which he was giving the concert, and often the
effect was increased by putting other crosses upon the four
sides of the house, the fetters and bridles of the patient's
horse, and even on the foot prints of the man, or the hoof
prints of the beast. Faith in the cross as a charm was
unwavering; "the cross of Christ has been hidden and is found,"
declared the Saxon soothsayer, and by the same token the lost
cattle will soon be discovered.

Many and marvelous were the methods to be followed scrupulously
by the sick. Cure the stomachache by catching a beetle in both
hands and throwing it over the left shoulder with both hands
without looking backward. Have you intestinal trouble? Eat
mulberries picked with the thumb and ring finger of your left
hand. Do you grow old before your time? Drink water drawn
silently DOWN STREAM from a brook before daylight. Beware of
drawing it upstream; your days will be brief. It reminds one of
the practice of the modern herb doctor in peeling the bark of
slippery elm DOWN, if you desire your cold to come down out of
your head, or peeling it up if you desire the cold to come up
out of your chest. One not desiring to place his trust in roots
and barks and herbs might turn for aid to the odd numbers, and
by reciting an incantation three or seven or nine times might
not only regain health, but recover his lost possessions. Or
the sufferer might transfer his disease by pressing a bird or
small animal to the diseased part and hastily driving the
creature away. The ever-willing and convenient family dog might
be brought into service on such an occasion by being fed a cake
made of barley meal and the sick man's saliva, or by being
fastened with a string to a mandrake root, which, when thus
pulled from the ground, tore the demon out of the patient.

The cure of children was a comparatively easy task for the
Anglo-Saxon doctor; for the only thing to be done was to have
the youngster crawl through a hole in a tree, the rim of the
hole thus kindly taking to itself all the germs or demons. So,
too, minor sores, warts and other blemishes might easily be
effaced by stealing some meat, rubbing the spot with it, and
burying the meat; as the meat decayed the blemish disappeared.
So to this day some Indians, and not a few Mexicans make a
waxen image of the diseased part, and place it before the fire
to melt as a symbol of the gradual waning of the illness. So,
too, the ancient Celts are said to have destroyed the life of
an enemy by allowing his waxen image to melt before the fire.

To cure a dangerous disease or the illness of a full-grown man
was, however, a much more difficult matter. Inflammation, for
instance, was the work of a stubborn demon, and stubborn,
therefore, must be the strife with him. Hence, dig around a
sorrel plant, sing three paternosters, pull up the plant, sing
"Sed libera nos a malo," pound five slices of the plant with
seven pepper corns, chant the psalm "Misere mei, Deus" twelve
times, sing "Gloria in excelsis, Deo," recite another
paternoster, at daybreak add wine to the plant and pepper
corns, face the east at mid-morning, make the sign of the
cross, turn from the east to the south to the west, and then
drink the mixture. Doubtless by this time the patient had
forgotten that he ever possessed inflammation.

Long did the superstitions in medicine persist. In Chaucer's
day, the fourteenth century, violent and poisonous drugs were
used, but luckily they were often administered to a little
dummy which the doctor carried about with him. As we read each
day in our newspapers of the various nostrums advertised as
curing every mortal ill, we may well wonder if the average
credulity has really greatly lessened after twelve centuries of
fakes and faith cures, and we almost long for the return of the
day when the medicine man practiced on a dummy instead of the
human body.



EMINENT AMERICAN NAMES

BY LAUREN HEWITT ASHE

UNIVERSITY OF PITTSBURGH

THE article entitled "The Racial Origin of Successful
Americans," by Dr. Frederick Adams Woods, which appeared in the
April (1914) issue of The Popular Science Monthly, set forth
some very interesting and instructive results. The methods used
to arrive at these results, however, do not seem to be such as
to establish them as final and conclusive.

It is not sufficient to consider merely the number of persons
bearing certain names in "Who's Who in America," for the
purpose of establishing the relative capability of various
nationalities. The percentage of the number bearing that name
in the city in question is the significant figure.

The writer has, therefore, taken the directories[1] of the four
American cities, which were the subjects of study in the
original article, and has estimated the number of persons of a
certain name living in each city by first counting the number
of names printed in a whole column of the directory and then
multiplying this figure by the number of columns occupied by
that name. The number of persons bearing the same name in
"Who's Who in America" (1912-1913) is then taken for each city.
The percentage is finally calculated of the number of the
"Who's Who in America" names in the number of those bearing
that name in the directories.

Bronx, City of New York, 1913. Trow Directory, Printing &

Annual Directory of the City of Chicago, 1913. Chicago

and Murdock Co., Publishers.

It seems best, furthermore, to narrow down the consideration
from the fifty most common names in each city to only those of
this number which are common to all four cities in order that
any one family may not have too great a weight. The names in
each city are then arranged according to the established
percentages.

The grouping of names as an indication of race or nationality
is taken from Robert E. Matheson's "Surnames in Ireland." It is
found to agree exactly with the grouping in the article by Dr.
Woods, who classified them from the table given in the New York
World Almanac and Encyclopedia for 1914, which table was, no
doubt, compiled from Matheson.

The nationality attributed to each name is indicated in the
tables below by capital letters in the parallel columns. In
some cases a name is shared by two or even three nationalities.
The percentages belonging to such names are attributed to each
of the sharing nationalities in making the final averages.
This, of course, is a serious source of error, since the
division of such names among the nationalities is not known. No
stress can be laid on our figures for the German, Scotch and
Scandinavian nationalities, because they contain so many of
these indecisive names.

The names in each city are then arranged in groups according to
their nationality and averages computed from the percentages
established for each name. These averages, which appear at the
bottom of each column, give a fair estimation of the capability
of the different nationalities, but are, nevertheless, open to
a few minor errors. For instance, the Germans head the list in
New York with 0.73 per cent. for only one third of a single
name, while the English rank second with a total of 15 5/6
names. The final averages for nationality, however, which
appear at the bottom of the fifth column and which are made
from the averages computed for each city, partly eliminate this
error and place the groups in their proper rank.

In order to make the results more conclusive, general averages
are drawn for each name from the percentages established for
that name in all four cities and are placed in the fifth column
according to their rank. Final averages of percentages for
nationalities are then made from this column, just as they were
for each city. The results obtained agree exactly with the
final averages made before and, therefore, are placed
coincident with them at the bottom of the fifth column.

The results finally arrived at seem to corroborate the
conclusions of Dr. Wood; namely, that in the four leading
American cities, New York, Chicago, Philadelphia and Boston,
"those of the English (and Scotch) ancestry are distinctly in
possession of the leading positions, at least from the
standpoint of being widely known." Yet it does not seem safe to
disregard entirely those other nationalities which rank so
closely with the English merely because of the small number of
them included in our consideration; for, as has been stated
above, we do not know what proportion of a certain name to
attribute to various nationalities.

There is one serious, but unavoidable, source of error,
moreover, which has apparently been overlooked. The conclusions
as to the relative intelligence of various races are drawn from
the number of names, belonging to these races, which appeared
in "Who's Who in America." According to the standards of this
compilation, eminence is very largely dependent upon education,
which does not give the emigrants, who are too poor to get
proper education, an equal opportunity to display their
intellectual power and, therefore, to be considered in the
above calculations. Races that immigrated predominantly in the
last century will be less handicapped than those which have
only recently immigrated in large numbers. It is very
difficult, however to know how much weight to place upon this
modifying influence.

Another source of error is the fact that certain nationalities
or races seem to have natural inclinations and desires to
follow in disproportionate numbers one kind of activity or
occupation and are content to let other people rise to those
positions which make them "the best-known men and women of the
United States." As Dr. Woods states, the Jews could not be
expected to show as large a percentage, since they largely turn
their attention to the banking, wholesale and retail trades, in
which they have been very successful, but in which eminence is
not correspondingly recognized in "Who's Who in America."

No comment is made on Jewish achievement, however, because no
Jewish name is among the fifty most common in all four cities,
and hence there are not enough numbers for study. But the
Irish, by their traditional devotion to politics and their
success in attaining the lower ranks of political leadership,
would seem to be in line for recognition in large numbers,
which they nevertheless do not attain.

In spite of these qualifications, however, it becomes apparent
that the statistics above established can not be rejected.
Although they do not exactly justify Dr. Woods's conclusions,
they at least show that the intellectual achievements of
different races vary. They also show that a much more extensive
study of the subject must be made before any conclusions can be
established as final.

We believe, therefore, that Dr. Woods's conclusion--that "there
have been a few notable exceptions, but broadly speaking all
our very capable men of the present day have been engendered
from the Anglo-Saxon element already here before the beginning
of the nineteenth century"--should be modified. A sounder
conclusion and, in fact, the only one that could be reached
through the results established above, would be this:
Achievement in those activities represented in "Who's Who in
America" is acquired disproportionately by stocks predominantly
Teutonic in comparison with the Irish.



A VISIT TO OENINGEN

BY PROFESSOR T. D. A. COCKERELL

UNIVERSITY OF COLORADO

AS the Rhine broadens on its approach to the Lake of Constance
or Boden Sea it flows through a region made classic by the
researches of scientific men. Here at low tide it is sometimes
possible to see wooden piles which in prehistoric times
supported the houses of the lake-dwelling folk, whose work is
so well represented in various museums, especially at Zurich.
From the river, on each side, the land rises rapidly, and the
rounded summits of the hills are well wooded. It is on the left
side of the Rhine, about two and a half miles below the town of
Stein, that we come to the famous locality for Miocene fossils,
the European representative of our Florissant in Colorado.

In all the books the fossil beds are said to be at Oeningen,
which is the name of a once celebrated Augustinian monastery
about two miles away. Actually, however, the locality is above
the village of Wangen, which is situated on the north bank of
the river. In some quite recent writings Oeningen (Wangen) is
referred to as being in Switzerland; it is in Baden, though the
opposite bank of the Rhine is Swiss. The error is natural,
since the fossils have chiefly been made known by the great
Swiss paleontologist Heer, of Zurich, and the best general
account of them is to be found in his book "The Primaeval World
of Switzerland," of which an excellent English translation
appeared in 1876.

It was at the Oeningen quarries, in the eighteenth century,
that a wonderful vertebrate fossil, some four feet long, was
discovered. A writer of that period, Scheuchzer, announced it
as Homo diluvii testis, a man witness of the deluge! Cuvier
knew better, and was able to demonstrate its relationship to
the giant salamanders of Eastern Asia and North America. It
forms, in fact, a distinct genus of Cryptobranchidae, which
Tschudi, apparently mindful of the early error, named Andrias;
though the proper name of the animal appears to be
Proteocordylus scheuchzeri (Holl.). The stone at Wangen was
used for building purposes, and at one time there were three or
four quarries actively worked. In earlier times the larger
fossils naturally attracted most attention, fishes, snakes,
turtles, fresh-water clams and a variety of leaves and fruits.
Such specimens were saved, and were sold and distributed to
many museums. The supply was good, yet at times not sufficient
for the market; so the monks at Oeningen, and others, would
carve artificial fossils out of the soft rock, coating them
with a brown stain prepared from unripe walnut shells. In later
years, during the middle part of the nineteenth century, the
period of Darwin, the great importance and interest of the
fossil beds came to be better appreciated. Dr. Oswald Heer,
professor at Zurich, an accomplished botanist and entomologist,
did perhaps nine tenths of the work, describing plants,
insects, arachnids and part of the Crustacea. The fishes were
described by Agassiz, and later by Winkler. The remaining
vertebrates were principally made known by E. von Meyer.

From 1847 to 1853 Heer published in three parts a great work on
fossil insects, largely concerned with those from Oeningen.[1]
In this and later writings he made known 464 species from this
locality; but in the latest edition of "The Primaeval World of
Switzerland" it is stated that there are 844 species, 384 of
these being supposedly new, and named, if at all, only in
manuscript.

[1] "Die Insektenfauna der Tertiargebilde von Oeningen und von
Radoboj in Croatien" (Leipzig: Engelmann).



My wife and I, having worked a number of years at Florissant,
were very anxious to see the corresponding European locality
for fossil insects. The opportunity came in 1909, when we were
able to make a short visit to Switzerland after attending the
Darwin celebration at Cambridge. We went first to Zurich, where
in a large hall in the University or Polytechnicum we saw
Heer's collections. A bust of Heer stands in one corner, while
one end of the room is covered by a large painting by Professor
Holzhalb, representing a scene at Oeningen as it may have
appeared in Miocene times, showing a lake with abundant
vegetation on its shores, and appropriate animals in the
foreground. Numerous glass-covered cases contain the
magnificent series of fossils, both plants and animals. Dr.
Albert Heim, professor of geology and director of the
Geological Museum, was most kind in showing us all we wanted to
see, and giving advice concerning the precise locality of the
fossil beds. Professor Heim is an exceedingly active and able
geologist, but neither he nor any one else has continued the
work of Heer, whose collections remain apparently as he left
them. The 384 supposedly new insects are still undescribed,
with a few possible exceptions. I had time only to critically
examine the bees, of which I found three ostensibly new forms.
Of these, one turned out to be a wasp,[2] one was
unrecognizable, but the third was a valid new species, and was
published later in The Entomologist. There can be no doubt that
Heer was too ready to distinguish species of insects in fossils
which were so poorly preserved as to be practically worthless,
consequently part of those he published and many of those he
left unpublished will have to be rejected. Nevertheless, the
Oeningen materials are extremely valuable, both for the number
of species and the good preservation of some of them. All
should be carefully reexamined, and the entomologist who will
give his time to this work will certainly be rewarded by many
interesting discoveries.

[2] Polistes, or very closely related to that genus.



Provided with instructions from Professor Heim, we started on
August 4 for Wangen, going by way of Constance. Thanks to the
map furnished by the Swiss railroad, we had no difficulty in
finding the Rosegarten Museum in Constance, which contains so
many interesting fossils and archeological specimens from the
surrounding region. At the moment we arrived, the old man in
charge was about to go to lunch, and we were assured that it
was impossible to get into the museum. It was then or never for
us, however; and when the necessary argument had been
presented, the curator not only let us in, but remained with us
to point out all the objects of interest, showing a great deal
of pride in the collection. The series of Oeningen fossils
could not, of course, rival that at Zurich; but it contained a
great many remarkable things, including some excellent insects.
We then boarded the river steamer, and, passing through the
Unter Sea, reached the small village of Wangen in the course of
the afternoon. This is not a tourist resort of any consequence;
the local guide book refers to it as follows: "Wangen (with
synagogue). Half an hour to the east is the Castle of Marbach,
now a well-appointed sanatorium for disorders of the nerves and
heart. To the west the romantic citadel Kattenhorn, formerly
used as a rendezvous by notorious highwaymen (at present in the
possession of a pensioned off German officer)." The guide
continues, calling our attention to "Oberstaad. Formerly a
castle, now a weaving mill for hose. Above it (448 meters) the
former celebrated Augustine monastery Oehningen. Near by
interesting and curious STONE FOSSILS are found." Thus the
visitor is likely to be misled as to the whereabouts of the
fossils, the tradition that they are at Oeningen having misled
the author of the guide. At Wangen we found a small but most
excellent hotel conducted by George Brauer, where we hastily
secured a room, and went out to hunt the fossil beds. We were
to walk over half an hour northward, up the hill, and look for
the quarries near the top of the high terrace above the
village. This we did, but at first without result. We passed a
small grassy pit, where some of the rock was visible, but it
did not look at all promising. We went back and forth, and up
the hill, until we were practically on the top. The country was
beautiful, and by the roadside we found magnificent red slugs
(Arion ater var. lamarckii[3]) and many fine snails, including
the so-called Roman snail, Helix pomatia. We accosted the
peasants, and enquired about the "fossilen." The word seemed to
have no meaning for them, so we tried to elucidate it in the
manner of the guide: where were the "stein fossilen"?
Immediately, with animation, we were shown a road going
westward to the town of Stein, where, it was naturally assumed,
the object of our enquiry would be found. Quite discouraged, we
wandered down the hill until we came to the pit we had noticed
when going up. Close by was a neat little cottage, and it
occurred to us to try our luck there as a last resort. We were
glad indeed when there appeared at the door an educated man,
who in excellent Shakespearian English volunteered at once to
show us the fossil beds. It was Dr. Ernst Bacmeister, a man of
considerable note in his own country, whose life and deeds are
duly recorded in "Wer ist's?" He came, with his wife and child,
to Wangen in the summer time, to enjoy these exquisite
surroundings, where he could write happily on philosophical
subjects, without much danger of interruption. Dr. Bacmeister
informed us that the poor little pit close by was in fact one
of the noted quarries, with the sides fallen in and the debris
overgrown with herbage. A short distance away we were shown the
others, in the same discouraging condition.

[3] The earliest name for this richly colored variety is Limax
coccineus Gistel, but it is not Limax coccineus Martyn, 1784;
so the next name, lamarckii, prevails.



One could see that there had once been considerable
excavations, but the good layers were now deeply covered by
talus, and could only be exposed after much digging. It was
about thirty years since the pits had been worked. Dr.
Bacmeister found for us a strong country youth, Max Deschle,
who dug under our direction all next day in the quarry near the
house. The rock is not so easy to work as that at Florissant,
and it does not split so well into slabs, but we readily found
a number of fossils. Most numerous were the plants; leaves of
cinnamon (Cinnamomurn polymorphum), soapberry (Sapindus
falcifolius), maple (Acer trilobatum), grass (Poacites loevis)
and reeds (Phragmites oeningensis), with twigs of the conifer
Glyptostrobus europoeus. We obtained a single seed of the very
characteristic Podogonium knorrii. Certain molluscs were
abundant; Planorbis declivis, Lymnoea pachygaster, Pisidium
priscum, with occasional fragments of the mussel Anodonta
lavateri. Ostracods, Cypris faba, were also found. The best
find, however, was a well-preserved fish, the lepidocottus
brevis (Agassiz), showing in the region of the stomach its last
meal, of Planorbis declivis. This greatly interested Max, who
during the rest of the day chanted, as he swung the pick,
"Fischlein, Fischlein, komme!"--but no other Fischlein was
apparently within hearing distance. Not a single insect was
obtained, except that on the talus at one of the other quarries
I picked up a poorly preserved beetle, apparently the Nitidula
melanaria of Heer.

We left Wangen on the morning of August 6, and proceeded up the
Rhine to Schaffhausen and Basle. At Basle we found a certain
number of Oeningen (Wangen) fossils in the museum.

Comparing Wangen with Florissant, it appears that the Colorado
locality is more extensive, more easily worked, and provides
many more well-preserved fossils. On the other hand, Wangen has
proved far richer in vertebrates and crustacea, and on the
whole gives us a better idea of the fauna as it must have
existed. Florissant far exceeds Wangen in the number of
described species, but this is only because it has so many more
insects. Each locality furnishes us with extraordinarily rich
materials, enabling us to picture the life of Miocene times.
Each, by comparison, throws light on the other, and while the
period represented is not sufficiently remote to show much
evidence of progressive evolution, it is hard to exaggerate the
value of the facts for students of geographical distribution.
Much light may also be thrown on the relative stability of
specific characters.

Work on the Florissant fauna is going forward, though not so
fast as one could wish. It is very much to be hoped that the
Wangen quarries will receive attention before many years have
passed. Labor is comparatively cheap in Germany, and with a
force of a dozen men it would not take long to open up the
quarries and get at the best beds. It is really extraordinary
that no one has seen and taken advantage of the opportunities
presented. Probably no obstacles of any consequence would be
put in the way; at least the owner of the quarries came by when
we were digging, and expressed only his good will. With new
researches in the field, combined with studies of the rich
materials awaiting examination at Zurich and elsewhere, no
doubt the knowledge we possess of the European Miocene fauna
could be very greatly increased, to the advantage of all
students of Tertiary life.



THE THEORY AND PRACTISE OF FROST FIGHTING[1]

[1] Some of the instruments used were obtained through a grant
from the Elizabeth Thompson Science Fund.

BY ALEXANDER McADIE

BOTCH PROFESSOR OF METEOROLOGY, HARVARD UNIVERSITY

ONLY in recent years have aerologists given much attention to
the slow-moving currents of the lower strata of the atmosphere.
These differ greatly from the whirls and cataracts of both low
and high levels which we familiarly know as the winds. The
upper and larger air streams play a part in the formation of
frost, and we do not underestimate their function; but
primarily it is a slow surface flow, almost a creeping of the
air near the ground, which controls the temperature and is
all-important in frost formation. So important is it that the
first law of frost fighting may be expressed as follows:

Where air is in motion and where there is good circulation,
frost is not so likely to occur as where the air is stagnant.

In other words frost in the ordinary meaning of the word is a
problem IN LOCAL AIR DRAINAGE. It is true that there are times
when with thorough ventilation and mixing of the air strata the
temperature will fall rapidly and damage from frost result; but
such conditions are perhaps more fittingly described as cold
waves or freezes, as distinguished from frosts. Thus, in
California during the first week of January, 1913, when there
was much air movement, the citrus fruit crop was damaged to the
extent of $20,000,000. The condition is generally referred to
as a frost, but it was quite different from the usual frost
conditions in that section. It is, however, interesting to note
that improved frost-fighting devices were used with much
success and the total savings aggregated about $25,000,000. The
orange growers also had the benefit of accurate forecasts and
expert advice and were thus able to provide fuel and labor in
advance. Passing over at present the larger disturbances, we
shall consider only the frosts of still nights. And it should
not be forgotten that the accumulated losses of these frosts
may equal the losses of the individual freezes, for the latter
occur at long intervals, while the quiet frosts of the early
fall and the late spring are recurrent, destroying flowers,
fruits and tender vegetation in many sections, year after year.

Air may flow in any direction, but attention has been centered
more upon the flow in a horizontal than in a vertical
direction. Thus none of the wind instruments used at Weather
Bureau stations gives any record of the up and down movement of
the air. In frosts of the usual type this vertical displacement
is all-important. True, there may be brought into the district,
by horizontal displacement, large masses of cold air and the
temperature thus materially lowered; but the marked INVERSION
of temperature occurs only when these horizontal currents or
winds are lulled. On windy nights, as is well known, there is
less likelihood of frost than on quiet nights, because of the
thorough mixing of the air vertically. There is then no
tendency for stratification and the formation of levels of
different temperature, followed by low surface temperature.

In general, the temperature falls as one rises in the air; but,
at times of frost, it is found that the higher levels are
warmer than the lower ones. The coldest stratum is found about
ten centimeters (four inches) above the ground; while at a
distance of ten meters temperatures are as much as five degrees
higher than at the ground.

It may be well to refer for a moment to the variations in
temperature known as inversions. In the accompanying diagram
it will be seen that the temperature falls with elevation, and
starting from the ground on a day when the temperature is near
the freezing point, 273 degrees A., one finds at a height of
seven thousand meters a fall of about forty degrees. It is not
easy to represent on a single diagram the variation in detail
and therefore we have divided the air column into three parts,
the scales being as one to a hundred.

The right-hand diagram shows the gradual rise in temperature
for a height of one meter and the peculiar inversion that
occurs a few centimeters above the ground. Unfortunately it is
in this layer where detailed temperature observations are most
needed that our instruments are least satisfactory. Ordinary
thermometers can not be relied on for such small differences
and the exploration of this stratum by self-recording
instruments is difficult. In the middle diagram is shown the
temperature gradient at times of frost, from the ground to a
height of one hundred meters. It will be seen that at a height
of fifty meters the temperature may be ten degrees higher; and
in general the rise continues with elevation. A good
illustration of a valley inversion is given by the chart of May
20, in which continuous records for three levels, 18, 64 and
196 meters above sea level, are given. At such times fruit or
flowers on hillsides escape damage from frost while in all the
depressions and low level places the injury may be marked.
These differences in temperature are not at all unusual and may
be anticipated on clear, still nights during spring, fall and
winter. Clouds or a moderate wind will prevent such an
inversion. We shall refer again to this in speaking of the
cranberry bogs of the Cape Cod district and the frost warnings
issued from Blue Hill Observatory.

The great inversion in the atmosphere, however, is that which
we have indicated as occurring at the height of nine thousand
meters. Above this, the temperature ceases to fall and we enter
what has been called the stratosphere or isothermal region. For
convenience we will call this upper change the MAJOR inversion
and the lower one near the ground the MINOR inversion. In some
ways we know more about the former than the latter. Strictly
speaking, the minor inversion is the chief factor in
determining local climate since it controls night and early
morning temperatures and in large measure the early or late
blooming of flowers and ripening of fruits.

Ordinarily cold air falls to the ground; but not always, for
under certain conditions cold, heavy air may actually rise,
displacing warm, lighter air. But such conditions can be
explained and there is no contradiction of the fundamental law
that if acted on only by gravity, cold air, being denser, will
settle to the ground and warm air, being lighter, will rise.
And there must be a certain relation between the height of the
level from which the cold air falls and the level to which the
warm air rises. In other words, we have to apply the laws of
falling bodies since a given mass of air, although invisible,
is matter and as subject to gravity as a cannon ball.

One of Galileo's most ingenious experiments consisted in
swinging a pendulum and then by means of a nail driven in
various positions intercepting the swing. He found that the bob
always rose to the same level whatever circuit it was forced to
take. But Galileo did not know what every schoolboy to-day
knows, that air exerts pressure and is subject to physical
processes like other matter, else he would certainly have given
to the world a delicate air pendulum; and devised experiments
on the movement of air that would have opened men's eyes to the
fascinating flow and counter-flow of the air, even on a
seemingly still night, one favorable for the formation of
frost.

The problem of the moving air mass, however, is more
complicated than it looks. For with the air is mixed a quantity
of water vapor. In a strict sense they are independent
variables, and the view set forth in most text-books that air
has a certain capacity for water vapor is misleading. We seldom
meet with pure, dry air. A cubic meter of such a gas mixture
would weigh 1,247 grams, at a temperature of 283 degrees A. (50
degrees F.). If chilled ten degrees, that is, to the freezing
point of water, it would weigh 46 grams more. So that by
cooling, air becomes denser and heavier. A cubic meter of a
mixture of air and water vapor at saturation, at the first
temperature above mentioned weighs only 1,242 grams, or five
grams less, and if this were cooled ten degrees the mixture
would weigh three grams less than the same volume of pure dry
air. We see that in each case the mixture of air and water
vapor weighs less than the air by itself. One would think that
by adding water vapor which, while light, still has weight, the
total weight would be the sum of both. It really is so,
notwithstanding the above figures, and the explanation of the
puzzle is that there was an increase in pressure with
expansion, so that the volume of the air and saturated vapor
was greater than one cubic meter. Since then a cubic meter of
air and saturated vapor weighs less than a cubic meter of dry
air at freezing temperature, speaking generally, we may expect
moist air to rise and dry air to fall. Consequently, if in
addition to falling temperature there is also a drying of the
air, we shall have an accelerated settling or falling of cold
dry air to the ground, which of course favors the formation of
frost. The water vapor plays also another role besides that of
varying the weight per unit volume. The heat received by the
ground consists of waves of a certain wavelength; but the heat
re-radiated by the ground consists of waves of longer
wave-length, and these so-called long waves (12 thousandths of
a millimeter) are readily absorbed by water vapor. Thus water
vapor acts like a blanket and holds the heat, preventing loss
of heat by radiation to space. Further on we shall speak of the
high specific heat of both water and water vapor as compared
with air and show the bearing of this in frost fighting; but at
present we may from what precedes formulate the second law of
frost fighting as follows: "Frost is more likely to occur where
the air is dry than where it is moist." It is also true that a
dusty atmosphere is less favorable for frost than a dust-free
atmosphere. Thus we may generalize and say that whatever favors
clear, still, dry air favors frost. The theory of successful
frost fighting then is to interfere with or prevent these
processes which as we have seen facilitate cooling close to the
ground. In what way can this best be done?

The most natural way would be by conserving the earth's heat,
which could be accomplished by covering plants with cloth,
straw, newspaper, or perhaps better still, modern weather-proof
sheeting, or in still another way by a cover of moistened dense
smoke, generally called a smudge. A second method would be by
means of direct application of heat; and this is accomplished
in orange groves by means of improved orchard heaters. Large
fires waste heat and are neither economical nor effective. A
third method would be based upon a mixing of the air strata,
thus getting the benefit of the warmer higher levels. Fourth,
advantage might be taken of some agency such as water or water
vapor, having a high specific heat. Finally, if the crop is of
a certain character such as the cranberry, it will be found
advisable to use sand, to drain and clean, here again making
use of the specific heat of some intermediary. And,
furthermore, any one of these methods may be combined with some
other method.

Regarding the first method, that of covers, it may be said that
the practice goes back to the early husbandmen; but only in the
last few years has the true function of the cover been properly
interpreted and we are still far from obtaining maximum
efficiency. Nor is there yet a suitable, scientific cover
available. Any medium that interferes with loss of heat through
free radiation before and after sunset is a cover. The best
type of cover is a cloud; and clouds, whether high or low, are
good frost protectors. On cloudy nights there is little
likelihood of frost; and when we can bring about the formation
of a layer of condensed water vapor we can practically
eliminate frost. We have mentioned above the fact that the
earth radiates the heat it has received not in the same but in
longer wave-lengths perhaps three times as long. These are
easily trapped and held by the vapor of water. Furthermore, the
rate of radiation is a function of the absolute temperature and
so the rapidity of loss depends somewhat upon the heat
received. Therefore the cover should be used as early in the
afternoon as possible, that is just before sunset. Aside from
the water cover or vapor cover there are cheap cloth screens,
fiber screens and in some places lath screens.

The second method, that of direct heating, has met with much
success in the orange groves of California and elsewhere.
Modern heating and covering methods date from experiments begun
in 1895. A number of basic patents granted to the writer in
this connection have been dedicated to the public. At the
present time there are on the market some twenty forms of
heaters, which have been described with more or less detail in
farm journals and official publications. It is not necessary to
refer to them further here. The fuel originally used was wood,
straw and coal, but these are now supplanted by crude oil or
distillate. It has also been seriously proposed to use electric
heaters; also to use gas in the groves. With modern orchard
heaters properly installed and handled, there is no difficulty
in raising the temperature of even comparatively large tracts
five degrees and maintaining a temperature above freezing, thus
preventing refrigeration of plant tissue.

The third method, that of utilizing the heat of higher levels
by mixing, has not yet been commercially developed; but the
methods of applying water, either in the spraying of trees or
the running of ditches or the flooding of bogs, together with
methods of sanding, cleaning; and draining, have all been
proved helpful. Methods available and most effective in one
section may not necessarily be effective in another section or
with different crop requirements. Certain devices most
effective in the groves of California may not answer in Florida
or Louisiana because of entirely different weather conditions.
In the Gulf coast states where water is available it may be
advantageously used to hold back ripening and retard
development until after the cold waves of middle and late
February have passed, whereas in the west coast sections
conditions are very different, water having a definite value
and the critical periods coming in late December or early
January.

In what precedes stress has been laid chiefly upon the fall of
temperature and the congelation of the water vapor. There is,
however, another important matter connected with injury to
plant tissue, and that is the rise in temperature AFTER the
frost. A too rapid defrosting may do considerable damage where
no damage was originally done by the low temperature. It is in
this connection that water may be used to great advantage.
Water, water-vapor and ice have, compared with other
substances, remarkably high specific heats. If the specific
heat under constant pressure of water be taken as unity, that
of ice is 0.49; of water-vapor 0.45 and of air 0.24. Or in a
general way we may say that water has four times the capacity
for heat that air has. Therefore it is apparent that water will
serve excellently to prevent rapid change in temperature. This
is important at sunrise and shortly after when some portion of
the chilled plant tissue may be exposed to a warming sufficient
to raise the temperature of the exposed portion ten degrees in
an hour. The latent heat of fusion of ice is 79.6 calories and
the latent heat of vaporization of water is nearly 600 calories
(a gram calorie is the amount of heat that will raise the
temperature of a gram of pure water one degree) or in exact
terms from 273 degrees A. to 274 degrees A. Therefore in the
process of changing from solid to liquid to vapor, as from ice
to water to vapor, there is a large amount of heat required.
The latent heat serves to prevent fall in temperature and also
serves to retard a too rapid rise. This does not mean, as is
generally assumed, that the air will be warmed, but it does
mean a retardation of temperature change. And it is essential
that the restoration of the tissues and juices to their normal
state be accomplished gradually, neither too rapidly nor yet
too slowly.

There is probably an optimum temperature for thawing or
defrosting frozen fruits and flowers. Finally the temperature
records as ordinarily obtained need careful interpretation. It
may be that the freezing point of liquids under pressure in the
plant cells or exposed to the air through the stomata is not
the same as in the free air. It is unfortunate too that in most
places data showing temperatures of soil, plant and air are of
doubtful character. A word of warning may be given against the
too ready acceptance of Weather Bureau records made in cities
and on the roofs of buildings. Garden and field conditions vary
greatly from these. It is further advisable to obtain a
continuous record of the temperature of evaporation such as is
shown by the records herewith. The two temperature curves made
simultaneously and easily read at any moment enable the
gardener or orchardist to forecast the probable minimum
temperature of the ensuing ten or twelve hours. But not always,
and some study is necessary. A slight increase in cloudiness or
a slight shift in wind direction will prevent the fall in
temperature which otherwise seemed probable. With a persistent
inversion of temperature there is sometimes an increasing
absolute humidity.

SUMMARY

The problem is many sided and we must consider the motion of
the air vertically as well as horizontally. Air gains and loses
heat chiefly by convection, and any gain or loss by conduction
may be neglected. The plant gains heat by convection, radiation
and perhaps by conduction of an internal rather than surface
character. The ground gains and loses heat chiefly by
radiation. But the whole process is complicated and may not
even be uniform. Frosts generally are preceded by a loss of
heat from the lower air strata, due to convection and a
horizontal translation of the air. Then follows an equally
rapid and great loss of heat by free radiation. There are minor
changes such as the setting free of heat in condensation and
the utilization in evaporation, but these latent heats are of
less importance than the actual transference of the air and
vapor and the removal of the latter as an absorber and retainer
of heat.

Frosts are recurrent phenomena reasonably certain to occur
within given dates, and, as pointed out above, the cumulative
losses are considerable. Methods of protection to be
serviceable must be available for more than one occasion, for
there is no profit in saving a crop on one night and losing it
on the succeeding night. But the effort is worth while.
Consider that the horticulturist regularly risks the labor of
many months on the temperatures of a few hours. An efficient
frost fighting device is in a way the entering wedge for
solving problems of climate control. One may not take a crop
indoors, it is true, but there is no valid reason, in the light
of what has been already accomplished, why at critical periods
which may be anticipated, the needed volume of surface air may
not be sufficiently warmed; and the losses which have
heretofore been considered inevitable be prevented.



THE PROGRESS OF SCIENCE

THE NEW YORK MEETING OF THE NATIONAL ACADEMY OF SCIENCES

THE National Academy of Sciences held its annual autumn meeting
during the third week of November in the American Museum of
Natural History. The central situation of New York City and its
scientific attractions led to a large meeting and an excellent
program There were present over sixty members, nearly one half
of a membership widely scattered over the country. When the
academy was established in 1863 as the adviser of the
government in scientific questions, the membership was limited
to fifty which was subsequently increased to 100, under which
it was kept until recently. The present distribution of the 141
members among different institutions in which there are more
than two is: Harvard, 19; Yale, 15; Chicago, 13; Johns Hopkins,
12; Columbia, 11; U. S. Geological Survey, 8; Carnegie
Institution, 5; California, Rockefeller Institute, Smithsonian,
4; Clark, Wisconsin, Cornell, Stanford, 3.

The scientific program of the meeting began with a lecture by
Professor Michael I. Pupin, of Columbia University, who
described the work on aerial transmission of speech of which no
authentic account has hitherto been made public. To Professor
Pupin we owe the discovery through mathematical analysis and
experimental work of the telephone relays which recently made
speech by wire between New York City and San Francisco
possible, and we now have an authoritative account of speaking
across the land and sea a quarter way round the earth. One
session of the academy was devoted to four papers of general
interest. Professor Herbert S. Jennings, of the Johns Hopkins
University, described experiments showing evolution in
progress, and Professor John M. Coulter, of the University of
Chicago, discussed the causes of evolution in plants Professor
B. B. Boltwood made a report on the life of radium which may he
regarded as a study of inorganic evolution. Professor Theodore
Richards, of Harvard University, spoke of the investigations
recently conducted in the Wolcott Gibbs Memorial Laboratory.
These are in continuation of the work accomplished by Professor
Richards in the determination of atomic weights, which led to
the award to him of a Nobel prize, the third to be given for
scientific work done in this country, the two previous awards
having been to Professor Michelson, of the University of
Chicago, in physics, and Dr. Carrel, of the Rockefeller
Institute, in physiology.

Of more special papers, some of which, however, were of general
and even popular interest, there were on the program 36,
distributed somewhat unequally among the sections into which
the academy is divided as follows: Mathematics, 0; Astronomy,
3; Physics and Engineering, 7; Chemistry, 1; Geology and
Paleontology, 6; Botany, 7; Zoology and Animal Morphology, 8;
Physiology and Pathology, 4; Anthropology and Psychology, 0. A
program covering all the sciences belongs in a sense to the
eighteenth rather than to the twentieth century; still there is
human as well as scientific interest in listening to those who
are leaders in the conduct of scientific work.

The academy was fortunate in meeting in the American Museum of
Natural History, where in addition to the scientific sessions
luncheon and an evening reception were provided. The museum has
assumed leadership both in exhibits for the public and in the
scientific research which it is accomplishing. The planning of
museum exhibits is itself a kind of research and in this
direction the American Museum, together with the National
Museum in Washington and the Field Museum in Chicago, now
surpasses any of the museums of the old world and in the course
of the next ten years will have no rivals there. It is
interesting that the city and an incorporated board of trustees
are able to cooperate in the support of the museum, as is also
the case with the Zoological Park and the Botanical Gardens
which the members of the academy visited in the course of the
meeting.



FREDERIC WARD PUTNAM

POWELL in Washington, Brinton in Philadelphia and Putnam in
Cambridge may be regarded as the founders of modern
anthropology in America. In the death of Putnam, at the age of
seventy-six years, we have lost the last of these leaders.

Putnam is often spoken of as the father of anthropological
museums because he, more than any other one person, contributed
to their development. He seems to have been a museum man by
birth, for at an early age we find him listed as curator of
ornithology in the Essex Institute of Salem, Mass. The Peabody
Museum of Archeology at Cambridge is largely his work, he
having entered the institution in 1875 and continued as its
head until his death. This institution is in many respects one
of the most typical anthropological museums in America. During
his college career Professor Putnam came under the influence of
Professor Louis Agassiz and was for several years an assistant
in the laboratory of that distinguished scientist. It seems
likely that this was the source of Professor Putnam's faith and
enthusiasm for the accumulation and preservation of concrete
data. As his interest in anthropology grew, he seems to have
sought to bring together in the Peabody Museum a collection of
scientific material that should have the same relation to the
new and developing science of anthropology as the collections
of Professor Agassiz's laboratory had to the science of
biology. Professor Putnam's great skill in developing the
Peabody Museum brought him into public notice and led to his
appointment as director of the anthropological section of the
World Columbian Exposition in Chicago The exhibit he prepared
made an unusual impression and it is said that largely to his
personal influence is due the interest of the late Marshall
Field in developing and providing for the museum which now
bears his name. After this achievement Professor Putnam was
invited by the American Museum of Natural History to organize
the department of anthropology which he proceeded to do upon
broad lines, giving it a status and impetus which is still
manifest. Later on he was invited to the University of
California to organize a department and a museum similar to the
one at Harvard and this also is now one of our leading
institutions. Thus it is clear that the history of American
anthropological museums is to a large extent the life history
of Professor Putnam.

The one new and important idea which Professor Putnam brought
into his museum work was that they should be in reality
institutions of research. Until that time they were chiefly
collections of curios brought together by purchase of
miscellaneous collections without regard to the scientific
problems involved. Professor Putnam's idea was that the museum
should go into the field and by systematic research and
investigation develop a definite problem, bringing to the
museum such illustrative and concrete data as should come to
hand in the prosecution of research. Professor Putnam also
played a large part in securing the recognition of anthropology
by universities and by his position at Harvard pointed the way
to mutual cooperation between museums and universities. He
possessed an unusual personality which enabled him to approach
and interest men of affairs so as to secure their financial
support for anthropological research and as a teacher he was
intensely interested in young men, offering them every possible
opportunity for advancement and never really losing personal
interest in them as long as he lived.

AT the recent meeting in Manchester, as we learn from Nature,
the general committee of the British Association unanimously
adopted the following resolution, which has been forwarded to
the Prime Minister, the Chancellor of the Exchequer and the
Presidents of the Board of Education and of Agriculture and
Fisheries: "That the British Association for the Advancement of
Science, believing that the higher education of the nation is
of supreme importance in the present crisis of our history,
trusts that his Majesty's government will, by continuing its
financial support, maintain the efficiency of teaching and
research in the universities and university colleges of the
United Kingdom."

John Pierpont Morgan, Thomas W. Lamont, Robert Bacon and Howard
Elliott.--The sum of about $400,000 has been subscribed in the
University of Michigan alumni campaign for $1,000,000 with
which to build and endow a home for the Michigan Union, as a
memorial to Dr. James B. Angell, president emeritus.
