+    <p>A lover of nature feels the fascination of the ferns though he may know little of
+    their names and habits. Beholding them in their native haunts, adorning the rugged
+    cliffs, gracefully fringing the water-courses, or waving their stately fronds on the
+    borders of woodlands, he feels their call to a closer acquaintance. Happy would he be
+    to receive instruction from a living teacher: His next preference would be the
+    companionship of a good fern book. Such a help we aim to give him in this manual. If
+    he will con it diligently, consulting its glossary for the meaning of terms while he
+    quickens his powers of observation by studying real specimens, he may hope to learn
+    the names and chief qualities of our most common ferns in a single season.</p>
+    <p>Our most productive period in fern literature was between 1878, when Williamson
+    published his "Ferns of Kentucky," and 1905, when Clute issued, "Our Ferns in Their
+    Haunts." Between these flourished D.C. Eaton, Davenport, Waters, Dodge, Parsons,
+    Eastman, Underwood, A.A. Eaton, Slosson, and others. All their works are now out of
+    print except Clute's just mentioned and Mrs. Parsons' "How to Know the Ferns." Both
+    of these are valuable handbooks and amply illustrated. Clute's is larger, more
+    scholarly, and more inclusive of rare species, with an illustrated key to the genera;
+    while Mrs. Parsons' is more simple and popular, with a naive charm that creates for
+    it a constant demand.</p>
+    <p>We trust there is room also for this unpretentious, but progressive, handbook,
+    designed to stimulate interest in the ferns and to aid the average student in
+    learning their names and meaning. Its geographical limits include the northeastern
+    states and Canada. Its nomenclature follows in the main the seventh edition of Gray's
+    Manual, while the emendations set forth in <i>Rhodora</i>, of October, 1919, and also
+    a few terms of later adoption are embodied, either as synonyms or substitutes for the
+    more familiar Latin names of the Manual, and are indicated by a different type. In
+    every case the student has before him both the older and the more recent terms from
+    which to choose. However, since the book is written primarily for lovers of Nature,
+    many of whom are unfamiliar with scientific terms, the common English names are
+    everywhere given prominence, and strange to say are less subject to change and
+    controversy than the Latin. There is no doubt what species is meant when one speaks
+    of the Christmas fern, the ostrich fern, the long beech fern, the interrupted fern,
+    etc. The use of the common names will lead to the knowledge and enjoyment of the
+    scientific terms.</p>
+    <p>A friend unfamiliar with Latin has asked for pointers to aid in pronouncing the
+    scientific names of ferns. Following Gray, Wood, and others we have marked each
+    accented syllable with either the grave (`) or acute (&acute;) accent, the former showing
+    that the vowel over which it stands has its long sound, while the latter indicates
+    the short or modified sound. Let it be remembered that any syllable with either of
+    these marks over it is the accented syllable, whose sound will be long or short
+    according to the slant of the mark.</p>
+    <p>We have appropriated from many sources such material as suited our purpose. Our
+    interest in ferns dates back to our college days at Amherst, when we collected our
+    first specimens in a rough, bushy swamp in Hadley. We found here a fine colony of the
+    climbing fern (<i>Lygodium</i>). We recall the slender fronds climbing over the low
+    bushes, unique twiners, charming, indeed, in their native habitat. We have since
+    collected and studied specimens of nearly every New England fern, and have carefully
+    examined most of the other species mentioned in this book. By courtesy of the
+    librarian, Mr. William P. Rich, we have made large use of the famous Davenport
+    herbarium in the Massachusetts Horticultural library, and through the kindness of the
+    daughter, Miss Mary E. Davenport, we have freely consulted the larger unmounted
+    collection of ferns at the Davenport homestead, at Medford,[1] finding here a very
+    large and fine assortment of <i>Botrychiums</i>, including a real <i>B. ternatum</i>
+    from Japan.</p>
+    <h5>[Footnote 1: Recently donated to the Gray Herbarium.]</h5>
+    <p>For numerous facts and suggestions we are indebted to the twenty volumes of the
+    <i>Fern Bulletin</i>, and also to its able editor, Mr. Willard N. Clute. To him we
+    are greatly obligated for the use of photographs and plates, and especially for
+    helpful counsel on many items. We appreciate the helpfulness of the <i>American Fern
+    Journal</i> and its obliging editor, Mr. E.J. Winslow. To our friend, Mr. C.H.
+    Knowlton, our thanks are due for the revision of the checklist and for much helpful
+    advice, and we are grateful to Mr. S.N.F. Sanford, of the Boston Society of Natural
+    History, for numerous courtesies; but more especially to Mr. C.A. Weatherby for his
+    expert and helpful inspection of the entire manuscript.</p>
+    <p>The illustrations have been carefully selected; many of them from original
+    negatives bequeathed to the author by his friend, Henry Lincoln Clapp, pioneer and
+    chief promoter of school gardens in America. Some have been photographed from the
+    author's herbarium, and from living ferns. A few are from the choice herbarium of Mr.
+    George E. Davenport, and also a few reprints have been made from fern books, for
+    which due credit is given. The Scott's spleenwort, on the dedication page, is
+    reprinted from Clute's "Our Ferns in Their Haunts."</p>

+    <p>Thoreau tells us, "Nature made a fern for pure leaves." Fern leaves are in the
+    highest order of cryptogams. Like those of flowering plants they are reinforced by
+    woody fibres running through their stems, keeping them erect while permitting
+    graceful curves. Their exquisite symmetry of form, their frequent finely cut borders,
+    and their rich shades of green combine to make them objects of rare beauty; while
+    their unique vernation and method of fruiting along with their wonderful mystery of
+    reproduction invest them with marked scientific interest affording stimulus and
+    culture to the thoughtful mind. By peculiar enchantments these charming plants allure
+    the ardent Nature-lover to observe their haunts and habits.</p>
+    <br />
+    <br />
+    <center>
+<pre>
+  "Oh, then most gracefully they wave
+  In the forest, like a sea,
+  And dear as they are beautiful
+  Are these fern leaves to me."
+</pre>
+    </center>
+    <p>As a rule the larger and coarser ferns grow in moist, shady situations, as swamps,
+    ravines, and damp woods; while the smaller ones are more apt to be found along
+    mountain ranges in some dry and even exposed locality. A tiny crevice in some high
+    cliff is not infrequently chosen by these fascinating little plants, which protect
+    themselves from drought by assuming a mantle of light wool, or of hair and chaff,
+    with, perhaps, a covering of white powder as in some cloak ferns--thus keeping a
+    layer of moist air next to the surface of the leaf, and checking transpiration.</p>
+    <p>Some of the rock-loving ferns in dry places are known as "resurrection" ferns,
+    reviving after their leaves have turned sere and brown. A touch of rain, and lo! they
+    are green and flourishing.</p>
+    <p>Ferns vary in height from the diminutive filmy fern of less than an inch to the
+    vast tree ferns of the tropics, reaching a height of sixty feet or more.</p>
+    <br />
+    <br />
+
+    <h4>REPRODUCTION</h4>
+    <br />
+    <br />
+    <p>Ferns are propagated in various ways. A frequent method is by perennial
+    rootstocks, which often creep beneath the surface, sending up, it may be, single
+    fronds, as in the common bracken, or graceful leaf-crowns, as in the cinnamon fern.
+    The bladder fern is propagated in part from its bulblets, while the walking leaf
+    bends over to the earth and roots at the tip.</p>
+    <br />
+    <center>

+       border="0"
+       alt="Fern Reproduction by the Prothallium" />
+      <p>[Illustration: MALE SHIELD FERN. Fern Reproduction by the Prothallium]</p>
+    </center>
+    <p>Ferns are also reproduced by spores, a process mysterious and marvellous as a
+    fairy tale. Instead of seeds the fern produces spores, which are little one-celled
+    bodies without an embryo and may be likened to buds. A spore falls upon damp soil and
+    germinates, producing a small, green, shield-shaped patch much smaller than a dime,
+    which is called a proth&aacute;llium (or prothallus). On its under surface delicate root
+    hairs grow to give it stability and nutriment; also two sorts of reproductive organs
+    known as anther&iacute;dia and archeg&ograve;nia, the male and female growths analogous to the
+    stamens and pistils in flowers. From the former spring small, active, spiral bodies
+    called &aacute;ntheroz&ograve;ids, which lash about in the moisture of the proth&aacute;llium until they
+    find the archeg&ograve;nia, the cells of which are so arranged in each case as to form a
+    tube around the central cell, which is called the &ograve;&ouml;sphere, or egg-cell, the point to
+    be fertilized. When one of the entering &aacute;ntheroz&ograve;ids reaches this point the desired
+    change is effected, and the canal of the archeg&ograve;nium closes. The empty &ograve;&ouml;sphere
+    becomes the quickened &ograve;&ouml;sphore whose newly begotten plant germ unfolds normally by
+    the multiplication of cells that become, in turn, root, stem, first leaf, etc., while
+    the proth&aacute;llium no longer needed to sustain its offspring withers away.[1]</p>
+    <h5>[Footnote 1: In the accompanying illustration, it should be remembered that the
+    reproductive parts of a fern are microscopic and cannot be seen by the naked
+    eye.]</h5>
+    <p>Fern plants have been known to spring directly from the proth&aacute;llus by a budding
+    process apart from the organs of fertilization, showing that Nature "fulfills herself
+    in many ways."[2]</p>
+    <h5>[Footnote 2: The scientific term for this method of reproduction is ap&oacute;gamy
+    (apart from marriage). Sometimes the prothallus itself buds directly from the frond
+    without spores, for which process the term ap&oacute;spory is used. (Meaning, literally,
+    without spores.)]</h5>
+    <br />
+    <br />
+
+    <h4>VERNATION</h4>
+    <br />
+    <br />
+    <p>All true ferns come out of the ground head foremost, coiled up like a
+    watch-spring, and are designated as "fiddle-heads," or crosiers. (A real crosier is a
+    bishop's staff.) Some of these odd young growths are covered with "fern wool," which
+    birds often use in lining their nests. This wool usually disappears later as the
+    crosier unfolds into the broad green blade. The development of plant shoots from the
+    bud is called vernation (Latin, <i>ver</i> meaning spring), and this unique uncoiling
+    of ferns, "circinnate vernation."</p>
+    <br />
+    <br />
+
+    <h4>VEINS</h4>
+    <br />
+    <br />
+    <p>The veins of a fern are free, when, branching from the mid-vein, they do not
+    connect with each other, and simple when they do not fork. When the veins intersect
+    they are said to anastomose (Greek, an opening, or network), and their meshes are
+    called ar&egrave;ol&aelig; or &aacute;reoles (Latin, <i>areola</i>, a little open space).</p>
+    <br />
+    <br />

+    <table summary="">

+        <td>
+          <h4>EXPLANATION OF TERMS</h4>
+          <br />
+          <br />
+
+          <p>A frond is said to be pinnate (Latin, <i>pinna</i>, a feather), when its
+          primary divisions extend to the rachis, as in the Christmas fern (Fig. 1). A
+          frond is bipinnate (Latin, <i>bis</i>, twice) when the lobes of the pinn&aelig;
+          extend to the midvein as in the royal fern (Fig. 2). These divisions of the
+          pinn&aelig; are called pinnules. When a frond is trip&iacute;nnate the last complete
+          divisions are called ultimate pinnules or segments. A frond is pinn&aacute;tifid when
+          its lobes extend halfway or more to the rachis or midvein as in the middle
+          lobes of the pinn&aacute;tifid spleenwort (Fig. 3). The pinn&aelig; of a frond are often
+          pinn&aacute;tifid when the frond itself is pinnate; and a frond may be pinnate in its
+          lower part and become pinn&aacute;tifid higher up as in the pinn&aacute;tifid spleenwort just
+          mentioned (Fig. 3).</p>
+          <p>The divisions of a pinn&aacute;tifid leaf are called segments; of a bipinn&aacute;tifid or
+          tripinn&aacute;tifid leaf, ultimate segments.</p>

+
+    <h4>SPOR&Agrave;NGIA AND FRUIT DOTS</h4>
+    <br />
+    <br />
+
+    <p>Fern spores are formed in little sacs known as spore-cases or spor&aacute;ngia (Fig. 4).
+    They are usually clustered in dots or lines on the back or margin of a frond, either
+    on or at the end of a small vein, or in spike-like racemes on separate stalks. Sori
+    (singular <i>sorus</i>, a heap), or fruit dots may be naked as in the polypody, but
+    are usually covered with a thin, delicate membrane, known as the indusium (Greek, a
+    dress, or mantle). The family or genus of a fern is often determined by the shape of
+    its indusium; e.g., the indusium of the woodsias is star-shaped; of the Dicksonias,
+    cup-shaped; of the aspleniums, linear; of the wood ferns, kidney-shaped, etc.</p>
+    <p>In many ferns the sporangia are surrounded in whole or in part by a vertical,
+    elastic ring (annulus) reminding one of a small, brown worm closely coiled (Fig. 4).
+    As the spores mature, the ring contracts and bursts with considerable force,
+    scattering the spores. The spores of the different genera mature at different times
+    from May to September. A good time to collect ferns is just before the fruiting
+    season. (For times of fruiting see individual descriptions or chronological chart on
+    page 220.)</p>
+    <br />
+    <br />
+
+    <h4>HELPFUL HINTS</h4>
+    <br />
+    <br />
+
+    <p>The following hints may be helpful to the young collector:</p>
+    <a
+     id="testeri"
+     name="testeri"><img
+     src="images/fern023.gif"
+     align="right"
+     alt="A good lens" /></a>
+    <p>1. A good lens with needles for dissecting is very helpful in examining the sori,
+    veins, glands, etc., as an accurate knowledge of any one of these items may aid in
+    identifying a given specimen. Bausch and Lomb make a convenient two-bladed pocket
+    glass for about two dollars.[1]</p>
+    <h5>[Footnote 1: In the linen tester here figured (cost $1.50) the lens is mounted in
+    a brass frame which holds it in position, enabling the dissector to use both hands. A
+    tripod lens will also be found cheap and serviceable.]</h5>

+    <p>2. Do not exterminate or weaken a fern colony by taking more plants than it can
+    spare. In small colonies of rare ferns take a few and leave the rest to grow. It is
+    decidedly ill-bred to rob a locality of its precious plants. Pick your fern leaf down
+    close to the root-stock, including a portion of that also, if it can be spared. Place
+    your fronds between newspaper sheets and lay "dryers" over them (blotting paper or
+    other absorbent paper). Cover with a board or slat frame, and lay on this a weight of
+    several pounds, leaving it for twenty-four hours; if the specimens are not then
+    cured, change the dryers. Mount the prepared specimens on white mounting sheets. The
+    regulation size is 16-1/2 by 11-1/2 inches. The labels are usually 3-3/4 by 1-3/4
+    inches. A sample will suggest the proper inscription.</p>

+    L. (Adder's Tongue)
+    Willoughby Lake, Vt.
+    August 19, 1911. Wet meadow.
+    Coll. X.Y.Z. Rather common
+    but often overlooked
+</pre>
+    <p>Place the label at the lower right-hand corner of the sheet, which is now ready to be
+    laid in the genus cover, usually of manila paper 16-1/2 by 12 inches. It is well to
+    jot down important memoranda at the time of collecting. This is the method in use at
+    the Gray Herbarium in Cambridge. It can, of course, be modified to suit one's own
+    taste or convenience. The young collector can begin by simply pressing his specimens
+    between the leaves of a book, the older and coarser the better; and he can mount them
+    in a blank book designed for the purpose, or if he has only a common blank book, he
+    can cut out some of the leaves, alternately with others left in place, as is often
+    done with a scrap book, that when the book is full it may not be crowded at the back.
+    Or he can use sheets of blank paper of any uniform size and mount the specimens on
+    these with gummed strips, and then group them, placing those of the same genus
+    together. Such an extemporized herbarium, though crude, will serve for a beginning,
+    while stimulating his interest, and advancing his knowledge of the ferns. Let him
+    collect, press, and mount as many varieties as possible, giving the name with date
+    and place of collecting, etc. Such a first attempt may be kept as a reminder of
+    pleasant hours spent in learning the rudiments of a delightful study.</p>
+    <p>We cannot insist too strongly upon the necessity of handling and studying the
+    living plant. Every student needs to observe for himself the haunts, habits, and
+    structure of real ferns. We would say to the young student, while familiarizing
+    yourself with the English names of the ferns, do not neglect the scientific names,
+    which often hold the key to their meaning. Repeat over and over the name of each
+    genus in soliloquy and in conversation until your mind instantly associates each fern
+    with its family name--"<i>Adiantum</i>," "<i>Polystichum</i>," "<i>Asplenium</i>,"
+    and all the rest. Fix them in the memory for a permanent asset. With hard study and
+    growing knowledge will come growing attachment. How our great expert, Mr. Davenport,
+    loved the ferns! He would handle them with gentle touch, fondly stroke their leaves,
+    and devoutly study their structure, as if inspired by the All-wise Interpreter.</p>
+<pre>
+  "Move along these shades
+  In gentleness of heart: with gentle hand
+  Touch--for there is a spirit in the woods."

+    <br />
+    <p>In this manual our native ferns are grouped scientifically under five distinct
+    families. By far the largest of these groups, and the first to be treated, is that of
+    the <i>real ferns (Polypodi&agrave;ce&aelig;)</i> with sixty species and several chief varieties.
+    Then follow the <i>flowering ferns (Osmund&agrave;ce&aelig;)</i> with three species; the <i>curly
+    grass</i> and <i>climbing ferns (Schiz&aelig;&agrave;ce&aelig;)</i> with two species; the <i>adder's
+    tongue</i> and <i>grape ferns (Ophiogloss&agrave;ce&aelig;)</i> with seven species; and the
+    <i>filmy ferns (Hymenophyll&agrave;ce&aelig;)</i> with one species.</p>
+    <p>Corresponding with these five families, the sporangia or spore cases of ferns have
+    five quite distinct forms on which the families are founded.</p>

+    <p>Fig. 1-4: Sporangia of the Five Families]</p>
+    <p>1. The Fern Family proper (<i>Polypodi&agrave;ce&aelig;</i>) has the spore cases stalked and
+    bound by a vertical, elastic ring (Fig. 1). The clusters of fruit-dots containing the
+    spore cases may be open and naked as in polypody (Fig. 2), or covered by an indusium,
+    as in the shield ferns (Fig. 3).</p>
+    <p>2. The Royal Fern Family (<i>Osmunda</i>) has the spore cases stalked with only a
+    rudimentary ring on one side, which opens longitudinally (Fig. 4).</p>
+    <p>3. The Climbing Fern Family (<i>Lygodium, Schiz&aelig;a</i>) has the spore cases sessile
+    in rows; they are small, nut-like bodies with the elastic ring around the upper
+    portion (Fig. 5).[1]</p>
+    <h5>[Footnote 1: These figures are enlarged.]</h5>
+    <p>4. The Adder's Tongue Family (<i>Ophiogl&oacute;ssum, Botr&yacute;chium</i>) has simple spore
+    cases without a ring, and discharges its spores through a transverse slit (Fig.
+    6).</p>
+    <p>5. The Filmy Fern Family (<i>Trich&oacute;manes</i>) has the spore cases along a
+    bristle-like receptacle and surrounded by an urn-shaped, slightly two-lipped
+    involucre; ring transverse and opening vertically (Fig. 7).</p>

+    and "King Charles in the oak," and any one may see or think he sees the outlines of

+    Also, in names of places as Ferney, Ferndale, Fernwood, and others. Although the

+    <p>The maidenhair has a superficial resemblance to the meadow rue, which also sheds
+    water, but it may be known at once by its black, shining stalks with their divisions
+    all borne on one side. It is indeed a most delicate fern, known and admired by every
+    one. The term maidenhair may have been suggested by the black, wiry roots growing
+    from the slender rootstock, or by the dark, polished stems, or, as Clute explains it,
+    "because the black roots, like hair, were supposed, according to the 'doctrine of
+    signatures' to be good for falling hair, and the plant was actually used in the
+    'syrup of capillaire'[A] (<i>Am. Botanist</i>, November, 1921). While the maidenhair
+    is not very common, it is widely distributed, being found throughout our section,
+    westward to California, and northward to the British Provinces.</p>
+    <p>"Though the maidenhair has a wide range, and grows abundantly in many localities,
+    it possesses a quality of aloofness which adds to its charm. Its chosen haunts are
+    dim, moist hollows in the woods, or shaded hillsides sloping to the river. In such
+    retreats you find the feathery fronds tremulous on their glistening stalks, and in
+    their neighborhood you find, also, the very spirit of the woods."<br />

+    <p>Another name is "the winter brake," as its fronds remain green throughout the

+    preference for limestone, and often in full sun. In large and mature fronds its pinn&aelig;
+    are apt to be extremely irregular. While its stipes are purplish, its leaves are
+    bluish-green, and its scales light-brown or yellow. Strange to say, this brake of the
+    cliffs thrives in cultivation. Woolson says of it, "This fern is interesting and
+    valuable. It is not only beautiful in design, but unique in color, a dark blue-green
+    emphasizing all the varying tints about it--a first-class fern for indoor winter
+    cultivation. It is a rapid grower, flourishing but a few feet from coal fire or

+    <h4><i>Cryptogr&aacute;mma densa. Pella&egrave;a densa</i></h4>
+    <p>Modern botanists are inclined to place the dense cliff brake and the slender cliff
+    brake under the genus <i>Cryptogr&aacute;mma</i>, which is so nearly like <i>Pellaea</i>
+    that one hesitates to choose between them. The word Cryptogr&aacute;mma means in Greek a
+    <i>hidden line</i>, alluding to the line of sporangia hidden beneath the reflexed
+    margin.</p>
+    <p>The dense cliff brake may be described as follows:</p>
+    <p>Stipes three to nine inches tall, blades one to three inches, triangular-ovate,
+    pinnate at the summit, and tripinnate below. Segments linear, sharp-pointed, mostly
+    fertile, having the margins entire and recurved, giving the sori the appearance of
+    half-open pods. Sterile fronds sharply serrate. Stipes in dense tufts
+    ("<i>densa</i>") slender, wiry, light-brown.</p>
+    <p>This rare little fern is a northern species and springs from tiny crevices in
+    rocks, preferring limestone. Like many other rock-loving species, it produces spores
+    in abundance, having no other effective means of spreading, and its fertile fronds
+    are much more numerous than the sterile ones, and begin to fruit when very small.

+    <p>The parsley fern is the typical species of the genus <i>Cryptogr&aacute;mma</i>. The
+    indusium is formed of the altered margin of the pinnule, at first reflexed to the
+    midrib, giving it a pod-like appearance, but at length opening out flat and exposing
+    the sporangia. Clute, speaking of this fern as "the rock brake," calls it a border
+    species, as its home is in the far north--Arctic America to Lake Huron, Lake
+    Superior, Colorado and California.</p>

+    <p>Mostly small southern ferns growing on rocks, pubescent or tomentose with much

+    afterwards more or less confluent. The indusium whitish and sometimes herbaceous,
+    formed of the reflexed margin of the lobes or of the whole pinnule. Veins free, but
+    often obscure. Most of the ferns of this genus grow in dry, exposed situations, where
+    rain is sometimes absent for weeks and months. For this reason they protect
+    themselves by a covering of hairs, scales or wool, which hinders the evaporation of
+    water from the plant by holding a layer of more or less saturated air near the
+    surface of the frond. (In Greek the word means <i>lip flower</i>, alluding to the
+    lip-like indusia.)</p>

+    as the others. Pinnules distant, the reflexed, narrow margin forming a continuous,
+    membranous indusium. Stipe stout, dark brown, densely woolly.</p>
+    <p>By donning its thick coat of wool this species is prepared to grow in the most

+    <p>The following species, which are often two to three feet high and grow in rich
+    soil, are quite different in appearance and habits from the small rock spleenworts
+    just described. Some botanists have kept them in the genus <i>Asplenium</i> because
+    their sori are usually rather straight or only slightly curved, but others are
+    inclined to follow the practice of the British botanists and put them into a separate
+    group under <i>Ath&yacute;rium</i>. Nearly all agree that the lady fern, with its variously
+    curved sori, should be placed here, and many others would place the silvery
+    spleenwort in the same genus, partly because of its frequently doubled sori. In
+    regard to the last member of the group, the narrow-leaved spleenwort, there is more
+    doubt. The sori taken separately would place it with the <i>Aspleniums</i>, but
+    considering its size, structure, habits of growth and all, it seems more closely

+    <h4>(1) THE UPLAND LADY FERN. ATH&Yacute;RIUM ANG&Uacute;STUM</h4>
+    <h4><i>Aspl&egrave;nium F&igrave;lix-femina</i></h4>
+    <p>The rootstock or rhizome of the Upland Lady Fern here pictured shows how the
+    thick, fleshy bases of the old fronds conceal the rootstock itself. In the Lowland
+    Lady Fern the rootstock is but slightly concealed by old stipe bases, and so may be
+    distinguished from its sister fern.</p>
+    <p>One design of such rootstocks is to store up food (mostly starch), during the
+    summer to nourish the young plants as they shoot forth the next spring. The undecayed
+    bases of the old stipes are also packed with starch for the same purpose.</p>

+    <p>Rootstocks horizontal, quite concealed by the thick, fleshy bases of old fronds.
+    Scales of the long, tufted stipes dark brown. Indusium curved, often
+    horseshoe-shaped, usually toothed or fringed with fine hairs, but without glands.
+    Fronds bipinnate, one to three feet high, widest near the middle.</p>
+    <p>This is the common species of northern New England and the Canadian Provinces. The
+    fronds differ very widely in form and a great many varieties have been pointed out,
+    but the fern student, having first learned to identify the species, will gradually
+    master the few leading varieties as he meets them.</p>
+    <p>Those growing in warm, sunny places where the fruit-dots when mature incline to
+    cover the whole back of the frond are called "sun forms." These are varieties T&Yacute;PICUM
+    and EL&Agrave;TIUS, both with the pinn&aelig; obliquely ascending (including variety
+    <i>angustum</i> of D.C. Eaton), but the latter has broader fronds with the pinnules
+    of the sterile fronds oblong-lanceolate, somewhat acute and strongly toothed or
+    pinnatifid.</p>

+    <p>[Illustration: Varieties of Lady Fern Left to right--lst and 2nd, Var. <i>typicum;
+    3d, elatius; 4th, rubellum; 5th, uncertain, perhaps confertum</i>]</p>
+    <p>Var. RUB&Eacute;LLUM has the sori distinct even when mature; its pinnules stand at a wide
+    angle from the rachis of the pinna and are strongly toothed or pinnatifid with obtuse
+    teeth. This variety favors regions with cool summers, or dense shade in warmer
+    regions. The term RUB&Eacute;LLUM alludes to the reddish stems so often seen but this sign
+    alone may not determine the variety. It occurs throughout the range of the species,
+    being a common New England fern. Fernald remarks that this is also a common form of
+    the species in southern Nova Scotia.</p>
+    <p>Among other varieties named by Butters are CONF&Eacute;RTUM, having the pinnules
+    irregularly lobed and toothed; joined by a membranous wing, the lobes of the pinnules
+    broad and overlapping, giving the fern a compact appearance; LACINI&Agrave;TUM with pinnules
+    very irregular in size and shape, with many long, acute teeth, which project in
+    various directions. "An abnormal form which looks as if it had been nibbled when
+    young."</p>
+    <p>These varieties are represented in the Gray Herbarium.</p>
+    <h4>(2) THE LOWLAND LADY FERN</h4>
+    <h4>ATH&Yacute;RIUM ASPLENI&Ograve;IDES</h4>
+    <p>Rootstocks creeping, not densely covered with the persistent bases of the fronds.
+    Stipes about as long as the blade. Scales of the stipe very few, seldom persistent,
+    rarely over 3-16 of an inch long. Fronds narrowly deltoid, lanceolate, widest near
+    the base, the second pair of pinn&aelig; commonly longest. Indusia ciliate, the cilia
+    (hairs) ending in glands. Spores dark, netted or wrinkled.</p>
+    <a

+     alt="Lowland Lady Fern" /></a>
+    <p>[Illustration: Lowland Lady Fern. ATHYRIUM ASPLENIOIDES (From the Gray
+    Herbarium)]</p>
+    <p>The following two forms are named by Butters:</p>
+    <p>F. T&Yacute;PICUM. The usual form frequent in eastern Massachusetts, Rhode Island,
+    Connecticut, New York, Pennsylvania, North Carolina, Ohio, and Missouri.</p>
+    <p>F. SUBTRIPINN&Agrave;TUM. An unusually large and rare form with triangular, lanceolate,
+    and pinnatifid pinnules, having blunt, oblong segments. Wet situations in half shade.
+    Massachusetts, West Virginia, and Virginia.</p>
+    <p>Our lowland or southern lady fern flourishes in the southern states, comes up the
+    Atlantic Coast until it meets the upland or northern species in Pennsylvania and
+    southern New England, and their identification can hardly fail to awaken in the
+    student a keen interest.</p>
+    <p>Our American botanists are inclined to think that the real <i>Ath&yacute;rium
+    f&igrave;lix-f&eacute;mina</i> is not to be found in the northeastern United States, but is rather
+    a western species, with its habitat in California and the Rocky Mountain region and
+    identical with <i>Ath&yacute;rium cyclos&ograve;rum</i>.</p>
+    <p>But whatever changes may occur in the scientific name of the old <i>Ath&yacute;rium
+    f&igrave;lix-f&eacute;mina</i>, the name lady fern will not change, but everywhere within our
+    limits it will hold its own as a familiar term.</p>
+    <p>Underwood, writing of the lady fern under the genus <i>Asplenium</i>, mentions the
+    form "<i>ex&igrave;le</i>, small, starved specimens growing in very dry situations and often
+    fruiting when only a few inches high." He also mentions Eaton's "<i>ang&uacute;stum</i>,"
+    and alludes to the "Remaining sixty-three varieties equally unimportant that have
+    been described of this species."</p>
+    <p>The lady fern is common in moist woods, by walls and roadsides, and at its best is
+    a truly handsome species, although, like Mrs. Parsons, we have noticed that in the
+    late summer it loses much of its delicacy. "Many of its forms become disfigured and
+    present a rather blotched and coarse appearance." The lady fern has inspired several
+    poems, which have been quoted more or less fully in the fern books. The following
+    lines are from the pen of Calder Campbell:</p>
+    <p>"But not by burne in wood or dale Grows anything so fair As the palmy crest of
+    emerald pale Of the lady fern when the sunbeams turn To gold her delicate hair."</p>
+    <p>Referring, perhaps, to the fair colors of the unfolding crosiers revealing stipes
+    of a clear wine color in striking contrast with the delicate green of the
+    foliage.</p>
+    <p>In identifying this fern the novice should bear in mind the tendency of the curved
+    sori of youth to become straightened and even confluent with age, although such
+    changes are rather unreliable. Possibly the suggestion of the poetic Davenport may be
+    helpful to some that there is "An indefinable charm about the various forms of the
+    lady fern, which soon enables one to know it from its peculiarly graceful motion by
+    merely gently swaying a frond in the hand." Spores ripen in August.</p>
+    <p>The lady fern is very easy to cultivate and when once established is apt to crowd
+    aside its neighbors.</p>
+    <h4>(3) SILVERY SPLEENWORT. ATH&Yacute;RIUM ACROSTICH&Ograve;IDES</h4>
+    <h4><i>Aspl&egrave;nium acrostich&ograve;ides. Aspl&egrave;nium thelypter&ograve;ides</i></h4>
+    <p>Fronds two to four feet tall, pinnate, tapering both ways from the middle. Pinn&aelig;
+    deeply pinnatifid, linear-lanceolate, acuminate. Lobes oblong, obtuse, minutely
+    toothed, each bearing two rows of oblong or linear fruit-dots. Indusium silvery when
+    young.</p>

+    <p>[Illustration: Silvery Spleenwort. Athyrium acrostichoides]</p>
+    <p>The sterile fronds come up first and the taller, fertile ones do not appear until
+    late in June. Where there are no fruit-dots the hairs on the upper surface of the
+    fronds will help to distinguish it from specimens of the Marsh fern tribe, which it
+    somewhat resembles. The regular rows of nearly straight, clear-cut sori of the
+    fertile fronds are very attractive, and the lower ones, as well as those at the
+    slender tips of the pinn&aelig;, are frequently double.</p>
+    <p>Rich woods and moist, shady banks, New England to Kentucky and westward. Generally

+    <h4><i>Pol&yacute;stichum</i></h4>
+    <p>These have been grouped with the wood ferns, but are now usually placed under the
+    genus <i>Pol&yacute;stichum</i>, which has the sori round and covered with a circular
+    indusium fixed to the frond by its depressed center. The wood ferns, on the other
+    hand, have a kidney-shaped indusium attached to the fronds by the sinus.
+    (<i>Pol&yacute;stichum</i> is the Greek for many rows, the sori of some species being in
+    many ranks.)</p>
+    <h4>(1) THE CHRISTMAS FERN</h4>
+    <p><i>Pol&yacute;stichum acrostich&ograve;ides. Asp&iacute;dium acrostich&ograve;ides</i></p>

+    time. "Its mission is to cheer the winter months and enhance the beauty of the other
+    ferns by contrast." In transplanting, a generous mass of earth should be included and

+    <p>Under this designation Clute has grouped three of the shield ferns, which have a
+    close family resemblance, and has thus distinguished them from the wood ferns, which
+    also belong to the shield fern family.</p>
+    <h4>(1) THE MARSH FERN</h4>
+    <h4><i>Asp&iacute;dium thel&yacute;pteris</i>. THEL&Yacute;PTERIS PAL&Uacute;STRIS</h4>
+    <h4><i>Dry&oacute;pteris thel&yacute;pteris. Nephr&ograve;dium thel&yacute;pteris</i></h4>

+     alt="Marsh Fern" /></a>
+    <p>[Illustration: The Marsh Fern]</p>
+    <p>These are all good names and each one is worthy to be chosen. <i>Asp&iacute;dium</i>,
+    Greek for shield, in use for a century, adopted in all the seven editions of Gray's
+    Manual, is still the most familiar and pleasing term to its friends.
+    <i>Dry&oacute;pteris</i>, Greek for oak fern, has been chosen by Underwood and Britton and
+    Brown and has grown in favor. <i>Nephr&ograve;dium</i>, meaning kidney-like, favored by
+    Davenport, Waters and, of late, Clute, is a most fitting name. THEL&Yacute;PTERIS, meaning
+    lady fern, is found to be the earliest name in use and according to rule the correct
+    one.</p>
+    <a
+     id="marshmassi"
+     name="marshmassi"><img
+     src="images/fern112.jpg"
+     alt="Marsh Fern, in the mass" /></a>
+    <p>[Illustration: The Marsh Fern. <i>Aspidium Thelypteris</i>]</p>
+    <p>Fronds pinnate, lanceolate, slightly or not at all narrowed at the base. Pinn&aelig;
+    horizontal or slightly recurved, linear-lanceolate and deeply pinnatifid. Lobes
+    obtuse, but appear acute when their margins are reflexed over the sori. Veins once
+    forked. Indusium minute. Stipes tall, lifting the blades ten to fifteen inches above
+    the mud, whence they spring.</p>
+    <p>The fronds of the marsh fern are apt to be sterile in deep shade. It may be
+    readily distinguished from the New York fern by its broad base, instead of tapering
+    to very small pinn&aelig;; by its long stalk, lifting the blade up into the sunlight, and
+    by the revolute margins of the fertile fronds, which have suggested for it the name
+    of "snuff-box" fern. It is separated from the Massachusetts fern by its forked veins.
+    Common in marshes and damp woodlands; Canada to Florida and westward. While the marsh
+    fern loves moisture and shade it is sometimes found in dry, open fields. Miss Lilian
+    A. Cole, of Union, Me., reports a colony as growing on land above the swale in which
+    Twayblade and Adder's Tongue are found, "around rock heaps in open sunlight on clay
+    soil, but homely and twisted," as if a former woodsy environment had been long since
+    cleared away while the deserted ferns persisted.</p>
+    <h4>(2) MASSACHUSETTS FERN</h4>
+    <h4><i>Aspidium simul&agrave;tum</i>. THEL&Yacute;PTERIS SIMUL&Agrave;TA</h4>
+    <h4><i>Dry&oacute;pteris simulata. Nephr&ograve;dium simul&agrave;tum</i></h4>
+    <p>Fronds pinnate, one to three feet long, oblong-lanceolate, somewhat narrowed at
+    the base. Pinn&aelig; lanceolate, deeply pinnatifid, the lower most often turned inward.
+    Veins simple. Indusium glandular. Sori rather large.</p>
+    <p>Resembles the marsh fern, of which it was once thought to be a variety. In some
+    respects it is also like the New York fern, and is in fact intermediate between the
+    two.</p>

+    <p>That it is a distinct species was first pointed out by Raynal Dodge in 1880, and
+    it later was named <i>simul&agrave;tum</i>&gt; by Geo. E. Davenport because of its
+    similarity to a form of the lady fern. It may be identified by its thin texture and
+    particularly by its simple veins. On account of its close resemblance to the marsh
+    fern, Clute would call it "The lance-leaved Marsh Fern," instead of the irrelevant
+    name of Massachusetts Fern. Woodland swamps usually in deep shade, New England to

+     name="beech">THE BEECH FERNS</a></h3>
+    <p>The beech ferns are often classed with the polypodies, because, like them, they
+    have no indusium; but in other ways they are more akin to the wood ferns. Their
+    stipes are not jointed to the root stock, nor are their sori at the ends of the veins
+    as in the polypodies. We here place them with the wood ferns, retaining the familiar
+    name <i>Pheg&oacute;pteris</i> but giving THEL&Yacute;PTERIS as a synonym. The fruit-dots are
+    small, round and naked, borne on the back of the veins below the apex. Stipe
+    continuous with the rootstock. Veins free. (The name <i>Pheg&oacute;pteris</i> in Greek
+    means oak or beech fern.)</p>
+    <h4>(1) OAK FERN</h4>
+    <h4><i>Pheg&oacute;pteris dry&oacute;pteris</i>. THEL&Yacute;PTERIS DRY&Oacute;PTERIS</h4>
+    <p>Fronds glabrous, broadly triangular, ternate, four to seven inches broad, the
+    divisions widely spreading, each division pinnate at the base. Segments oblong,
+    obtuse, entire or toothed. Fruit-dots near the margin. Rootstock slender and creeping
+    from which fronds are produced all summer, in appearance like the small, ternate
+    divisions of the bracken.</p>
+    <p>This dainty fern has fronds of a delicate yellow-green, "the greenest of all green
+    things growing." Its ternate character is shown even in the uncoiling of the fronds,
+    the three round balls suggesting the sign of the pawnbroker. The parts of the oak
+    fern develop with great regularity, each pinna, pinnule and lobe having another
+    exactly opposite to it nearly always. In rocky woods, common northward; also in
+    Virginia, Kansas and Colorado. A fine species for cultivation at the base of the
+    artificial rockery.</p>

+    <h4>(3) BROAD BEECH FERN</h4>
+    <h4><i>Phegopteris hexagon&oacute;ptera</i></h4>
+    <h4>THEL&Yacute;PTERIS HEXAGON&Oacute;PTERA</h4>
+    <p>Fronds triangular, broader than long, seven to twelve inches broad, spreading more
+    or less horizontally at the summit of the stipe; pubescent and often glandular
+    beneath; pinn&aelig; fragrant, lanceolate, the lowest pair usually much larger than those
+    above, having the segments elongated and cut into lobes. Basal segments decurrent and
+    forming a many-angled wing along the main rachis. Fruit-dots small, near the
+    margin.</p>
+    <p>The broad beech fern is usually larger than its sister, the long beech fern, and
+    extends farther south, ranging from New England to Minnesota and southward to
+    Florida. It is sometimes called "six-angled polypody." According to Dodge it is most
+    common in Rhode Island and Connecticut. It prefers rather dry, open woods. It is said
+    to have a pleasant, ferny odor when bruised. August.</p>
+    <h4>(4) LONG BEECH FERN</h4>
+    <h4><i>Phegopteris polypodi&ograve;ides</i>. THEL&Yacute;PTERIS PHEG&Oacute;PTERIS</h4>

+    Pinn&aelig; lanceolate, acuminate, the lowest pair deflexed and standing forward; cut into
+    oblong, obtuse segments. Fruit-dots near the margin.</p>
+    <p>Compared with the broad beech fern this is the more northern species. While
+    usually quite distinct in structure, it sometimes approaches its sister fern rather

+    White Mountains and from Sunapee Lake in New Hampshire, and in the Green Mountains
+    south to central Vermont, New Brunswick and to Minnesota. Found also in Alaska and
+    Greenland. This much-coveted fern has a singularly sweet and lasting fragrance,
+    compared by some to strawberries, by others to new-mown hay and sweet brier leaves.
+    We have seen herbarium specimens that were mildly and pleasantly odorous after

+     <p>The ferns of this group, not counting the small fragrant fern, prefer the woods or
+    at least shady places. Although the genus <i>Pol&yacute;stichum</i> represents the true
+    shield ferns, the wood ferns are also thus designated, as their indusia have nearly
+    the shape of small, roundish shields. The old generic name for them all was
+    <i>Asp&iacute;dium</i> (meaning shield), first published in 1800. For a long time its chief
+    rival was <i>Nephr&ograve;dium</i> (kidney-like), 1803. Many modern botanists have preferred
+    the earlier name <i>Dry&oacute;pteris</i> (1763), meaning oak fern, alluding, perhaps, to
+    its forest-loving habits. THEL&Yacute;PTERIS, still earlier (1762), may supersede the
+    others.</p>

+    <h4>(1) MARGINAL SHIELD FERN, EVERGREEN WOOD FERN</h4>
+    <h4><i>Asp&iacute;dium margin&agrave;le</i>. THEL&Yacute;PTERIS MARGIN&Agrave;LIS</h4>
+    <h4><i>Dry&oacute;pteris margin&agrave;lis. Nephr&ograve;dium margin&agrave;le</i></h4>
+		<br />
+    <p>Fronds from a few inches to three feet long, ovate-oblong, somewhat leathery,
+    smooth, twice pinnate. Pinn&aelig; lanceolate, acuminate, broadest just above the base.
+    Pinnules oblong, often slightly falcate, entire or toothed. Fruit-dots large, round,
+    close to the margin. Rocky hillsides in rich woods, rather common throughout our
+    area. The heavy rootstock rises slightly above the ground and is clothed at the crown
+    with shaggy, brown scales. Its rising caudex, often creeping for several inches over
+    bare rocks, suggests the habit of a tree fern. In early spring it sends up a graceful
+    circle of large, handsome, bluish-green blades. The stipes are short and densely
+    chaffy. No other wood fern endures the winter so well. The fronds burdened with snow
+    lop over among the withered leaves and continue green until the new ones shoot up in
+    the spring. It is the most valuable of all the wood ferns for cultivation.</p>
+    <h4>(2) THE MALE FERN</h4>
+    <h4><i>Asp&iacute;dium F&igrave;lix-mas</i>. THEL&Yacute;PTERIS F&Igrave;LIX-MAS</h4>
+    <h4><i>Dry&oacute;pteris F&igrave;lix-mas. Nephr&ograve;dium F&igrave;lix-mas</i></h4>
+    <p>Fronds lanceolate, pinnate, one to three feet high growing in a crown from a
+    shaggy rootstock. Pinn&aelig; lanceolate, tapering from base to apex. Pinnules oblong,
+    obtuse, serrate at the apex, obscurely so at the sides, the basal incisely lobed,
+    distant, the upper confluent. Fruit-dots large, nearer the mid vein than the margin,
+    mostly on the lower half of each fertile segment.</p>
+    <p>The male fern resembles the marginal shield fern in outline, but the fronds are
+    thinner, are not evergreen, and the sori are near the midvein. Its use in medicine is
+    of long standing. Its rootstock produces the well-known <i>f&igrave;lix-mas</i> of the
+    pharmacist. This has tonic and astringent properties, but is mainly prescribed as a
+    vermifuge, which is one of the names given to it. In Europe it is regarded as the
+    typical fern, being oftener mentioned and figured than any other. In rocky woods,
+    Canada, Northfield, Vt., and northwest to the great lakes, also in many parts of the
+    world.</p>

+    brown to nearly black with a peculiar silky lustre.</p>
+    <p>A magnificent species, the tallest and largest of the wood ferns. It delights in
+    rich woodlands where there is limestone. Its range is from Canada to Kentucky. While
+    not common, there are numerous colonies in New England. It is reported from
+    Fairfield, Me., Spencer and Mt. Toby, Mass., and frequently west of the Connecticut
+    River. We have often admired a large and beautiful colony of it on the west side of

+    <p>Fronds one to two feet long, linear-oblong or lanceolate, pinnate, acute. Pinn&aelig;
+    two to three inches long, broadest at the base, triangular-oblong, or the lowest
+    triangular. Divisions oblong, obtuse, finely serrate or cut-toothed, those nearest
+    the rachis sometimes separate. Fruit-dots large, round, half way between the midvein
+    and the margin. Indusium smooth, naked, with a shallow sinus.</p>
+    <p>The short sterile fronds, though spreading out gracefully, are conspicuous only in
+    winter; while the fertile fronds, tall, narrow and erect, are found only in
+    summer.</p>
+    <p>It is one of our handsomest evergreen ferns and even the large sori, with their
+    dark spore cases and white indusia, are very attractive. The fertile pinn&aelig; have a way
+    of turning their faces upward toward the apex of the frond for more light. In moist

+    <h4><i>Asp&iacute;dium crist&agrave;tum X margin&agrave;le</i></h4>
+    <p>Both the crested fern and Clinton's fern appear to hybridize with the marginal

+    and the lower like <i>crist&agrave;tum</i>, including the veining and texture.</p>
+    <p>This form was discovered by Raynal Dodge, verified by Margaret Slosson and
+    described by Geo. E. Davenport, who had a small colony under cultivation in his fern
+    garden at Medford, Mass., and to him the writer and other friends are indebted for
+    specimens.</p>
+    <p>Found occasionally throughout New England and New Jersey. Other supposed hybrids
+    have been found between the marginal shield and the spinulose fern and its variety
+    <i>interm&egrave;dium</i>, and with Goldie's fern; also between the crested fern, including
+    Clinton's variety and each of the others mentioned; and, in fact, between almost all
+    pairs of species of the wood ferns, although we do not think they have been
+    positively verified. Still other species of ferns are known to hybridize more or

+    <h4><i>Aspidium Boottii</i>. THEL&Yacute;PTERIS BOOTTII</h4>
+    <h4><i>Dryopteris Boottii. Nephrodium Boottii</i></h4>
+    <p>Fronds one to three feet high, oblong-lanceolate, bipinnate, the upper pinn&aelig;
+    lanceolate, the lower triangular with spinulose teeth. Sori in rows each side of the
+    midvein, one to each tooth and often scattering on the lower pinules. Indusium large,
+    minutely glandular, variable.</p>
+    <p>This fern has been thought to be a hybrid between the crested and spinulose ferns,
+    but is now regarded as distinct. Like the crested fern its fertile fronds wither in
+    autumn, while its sterile blades remain green throughout the winter. It differs from
+    it, however, by being twice pinnate below, and from the typical spinulose fern by its
+    glandular indusium; but from the intermediate variety it is more difficult to
+    separate it, as that also has indusiate glands. The collector needs to study
+    authentic specimens and have in mind the type, with its rather long, narrow blade as
+    an aid to the verbal description, and even then he will often find it an interesting
+    puzzle. Shaded swamps throughout our area.</p>

+    broadly triangular, the upper ones elongated. Pinnules on the inferior side of the
+    pinn&aelig; often elongated, especially the lower pair, the pinnule nearest the rachis
+    being usually the longest, at least in the lowest pinn&aelig;. Pinnules variously cut into
+    spinulose-toothed segments. Indusium smooth, without marginal glands.</p>
+    <p>The common European type, but in this country far less common than its varieties.
+    They all prefer rich, damp woods, and because of their graceful outline and

+    <p>Var. <i>interm&egrave;dium</i> has the scales of the stipe brown with darker center.

+    <p>One of the most graceful and attractive of our native ferns; an object of beauty,
+    whether standing alone or massed with other growths. It is very easily cultivated and
+    one of the best for draping. "We may drape our homes by the yard," says Woolson,
+    "with the most graceful and filmy of our common ferns, the bladder fern." This fern
+    and the maidenhair were introduced into Europe in 1628 by John Tradescant, the first
+    from America.</p>
+    <p>It delights in shaded ravines and dripping hillsides in limestone districts. While
+    producing spores freely it seems to propagate its species mainly by bulblets, which,
+    falling into a moist soil, at once send out a pair of growing roots, while a tiny
+    frond starts to uncoil from the heart of the bulb. Mt. Toby, Mass., Willoughby

+    <h4>(2) THE COMMON BLADDER FERN</h4>
+    <h4><i>Cystopteris fr&aacute;gilis. Filix fr&aacute;gilis</i></h4>

+    on the winged rachis. Indusium appearing acute at the free end. Very variable in the
+    cutting of the pinnules.</p>
+    <p>The fragile bladder fern, as it is often called, and which the name
+    <i>fr&aacute;gilis</i> suggests, is the earliest to appear in the spring, and the first to
+    disappear, as by the end of July it has discharged its spores and withered away.
+    Often, however, a new crop springs up by the last of August, as if Nature were
+    renewing her youth. In outline the fragile bladder fern suggests the blunt-lobed
+    Woodsia, but in the latter the pinn&aelig; and pinnules are usually broader and blunter,
+    and its indusium splits into jagged lobes. Rather common in damp, shady places where
+    rocks abound. In one form or another, found nearly throughout the world though only
+    on mountains in the tropics.</p>

+    either small and open, or early bursting at the top into irregular pieces or lobes.
+    (Named for James Woods, an English botanist.)</p>
+    <h4>(1) RUSTY WOODSIA. <i>Wo&oacute;dsia ilv&eacute;nsis</i></h4>
+    <p>Fronds oblong-lanceolate, three to ten inches high, rather smooth above, thickly
+    clothed underneath with rusty, bristle-like chaff. Pinnate, the pinn&aelig; crowded,
+    sessile, cut into oblong segments. Fruit-dots near the margin often confluent at

+    <p>[Illustration: Rusty Woodsia, <i>Woodsia ilvensis</i>]</p>
+    <p>The rusty Woodsia is decidedly a rock-loving fern, and often grows on high cliffs
+    exposed to the sun; its rootstock and fronds are covered with silver-white, hair-like
+    scales, especially underneath. These scales turn brown in age, whence the name,
+    rusty. As the short stipes separate at the joints from the rootstock, they leave at
+    the base a thick stubble, which serves to identify the fern. Exposed rocks, Labrador
+    to North Carolina and westward. Rather common in New England. Said to be very
+    abundant on the trap rock hillocks about Little Falls, N.J., where it grows in dense
+    tufts.</p>

+    <p>[Illustration: Blunt-lobed Woodsia. <i>Woodsia obtusa</i>]</p>
+    <p>This is our most common species of Woodsia and it has a wider range than the
+    others, extending from Maine and Nova Scotia to Georgia and westward. On rocky banks
+    and cliffs. The sori of this species have a peculiar beauty on account of the

+    and far to the northwest. Not very common. It differs from the alpine species by the
+    absence of scales above the joint. As the name implies, the plant is smooth, except
+    for the chaffy scales at or near the rootstock, which mark all the Woodsias, and many
+    other ferns, and which serve as a protective covering against sudden changes in
+    extremes of heat and cold.</p>
+    <h4>(5) OREGON WOODSIA. <i>Wo&oacute;dsia oreg&agrave;na</i></h4>
+    <p>Fronds two to ten inches high, smooth, bright green, glandular beneath, narrowly
+    lance-oblong, bipinnatifid. Pinnse triangular-oblong, obtuse, pinnatifid. Segments
+    ovate or oblong, obtuse, crenate, the teeth or margin nearly always reflexed.
+    Indusium minute, concealed beneath the sorus, divided into a few beaded hairs.</p>
+    <p>Like the obtuse Woodsia this fern has no joint near the base of the stipe, but is
+    much smaller and has several points of difference. Limestone cliffs, Gasp&eacute; Peninsula,
+    southern shore of Lake Superior, Colorado, Oregon to the northwest. Its eastern limit
+    is northern Michigan.</p>
+    <h4>(6) ROCKY MOUNTAIN WOODSIA. <i>Wo&oacute;dsia scopul&igrave;na</i></h4>
+    <p>Fronds six to fifteen inches long [smooth], lanceolate, pinnatifid. Pinn&aelig;
+    triangular-ovate, the lowest pair shortened. Under surface of the whole frond
+    hispidulous with minute, white hairs and stalked glands. Indusium hidden beneath the
+    sporangia, consisting mostly of a few hair-like divisions.</p>
+    <p>In crevices of rocks, mountains of West Virginia, Gasp&eacute; Peninsula, Rocky
+    Mountains, and westward to Oregon and California.</p>

+    <p>Fronds one to three feet high, scattered along a creeping rootstock, broadly
+    triangular, deeply pinnatifid, with segments sinuately lobed or nearly entire. Veins
+    reticulated with fine meshes. The fertile fronds shorter, closely bipinnate with the
+    pinnules rolled up into berry-like structures which contain the spore cases. (The
+    name in Greek means a closed vessel, in allusion to the berry-like fertile segments.)
+    The sensitive fern is so called from its being very sensitive to frost. The sterile
+    and fertile fronds are totally unlike, the latter not coming out of the ground until
+    about July, when they appear like rows of small, green grapes or berries, but soon
+    turn dark and remain erect all winter, and often do not discharge their spores until
+    the following spring. The little berry-like structures of the fertile frond represent
+    pinnules, bearing fruit-dots, around which they are closely rolled. As Waters
+    remarks, "Most ferns hold the sori in the open hand, but the sensitive fern grasps
+    them tightly in the clenched fist."</p>
+    <p>Var. <i>obtusilobat&agrave;</i> is an abortive form with the fertile segments only

+    year. Sterile fronds appear throughout the summer, fertile ones in July. Seen from a
+    distance its graceful leaf-crowns resemble those of the cinnamon fern. An
+    intermediate form between the fertile and sterile fronds is sometimes found, as in
+    the sensitive fern. This handsome species thrives under cultivation. For grace and
+    dignity it is unrivaled, and for aggressiveness it is, perhaps, equaled only by the
+    lady fern. For the climax of beauty it should be combined with the maidenhair. The
+    ostrich fern is fairly common in alluvial soil over the United States and Canada.</p>

+    <h3><i>OSMUND&Agrave;CEAE</i></h3>
+    <p>This family is represented in North America by three species, all of which belong
+    to the single genus.</p>
+    <h4>OSM&Uacute;NDA</h4>
+    <p>The <i>osmundas</i> are tall swamp ferns growing in large crowns from strong,
+    thickened rootstocks; the fruiting portion of the fertile frond much contracted and
+    quite unlike the sterile. Sporangia large, globular, short-stalked, borne on the
+    margin of the divisions and opening into two valves by a longitudinal slit. Ring
+    obscure. (From Osmunder, a name of the god Thor.)</p>
+    <h4>(1) FLOWERING FERN, ROYAL FERN</h4>
+    <h4><i>Osm&uacute;nda reg&agrave;lis. Osmunda reg&agrave;lis</i>, var. SPECT&Agrave;BILIS</h4>
+    <p>Fronds pale green, one to six feet high; sterile part bipinnate, each pinna having
+    numerous pairs of lance-oblong, serrulate pinnules alternate along the midrib.
+    Fruiting panicle of the frond six to twelve inches long, brown when mature and
+    sometimes leafy.</p>
+    <p>A magnificent fern, universally admired. Well named by the great Linn&aelig;us,
+    <i>regalis</i>, royal, indeed, in its type of queenly beauty. The wine-colored stipes
+    of the uncoiling fronds shooting up in early spring, lifting gracefully their pink
+    pinn&aelig; and pretty panicles of bright green spore cases, throw an indescribable charm
+    over the meadows and clothe even the wet, stagnant swamps with beauty nor is the
+    attraction less when the showy fronds expand in summer and the green sporangia are
+    turned to brown. The stout rootstocks are often erect, rising several inches to a
+    foot above the ground, as if in imitation of a tree fern. The poet Wordworth hints at
+    somewhat different origin of the name from that given here.</p>

+   So stately of the Queen Osmanda named."

+    <h4>(2) INTERRUPTED FERN. CLAYTON'S FERN</h4>
+    <h4>Osmunda Claytoni&agrave;na</h4>
+    <p>Fronds pinnate, one to five feet high. Pinn&aelig; cut into oblong, obtuse lobes.
+    Fertile fronds taller than the sterile, having from one to five pairs of intermediate
+    pinn&aelig; contracted and bearing sporangia.</p>

+     alt="Interrupted Fern" /></a>
+    <p>[Illustration: Interrupted Fern. <i>Osmunda Claytoni&agrave;na</i>]</p>
+    <p>The fronds have a bluish-green tint; they mature their spores about the last of
+    May. The sterile fronds may be distinguished from those of the cinnamon fern by not
+    having retained, like those, a tuft of wool at the base of each pinna. Besides, in
+    Clayton's fern the fronds are broader, blunter and thinner in texture, and the
+    segments more rounded; the fronds are also more inclined to curve outwards. They turn
+    yellow in the fall, at times "flooding the woods with golden light," but soon smitten
+    by the early frosts they wither and disappear. The interrupted fern is rather common
+    in damp, rocky woods and pastures; Newfoundland to Minnesota, south to North Carolina
+    and Missouri. Although fond of moisture it is easily cultivated and its graceful
+    outlines make it worthy of a prominent place in the fern garden. Var. <i>dubia</i>
+    has the pinnules of the sterile frond widely separated, and the upper-middle ones
+    much elongated. Southern Vermont.</p>

+    <h4>(3) CINNAMON FERN. BRAKES</h4>
+    <p><i>Osmunda cinnamomea</i></p>
+    <p>Fronds one to six feet long, pinnate. Pinn&aelig; lanceolate, pinnatifid with oblong,
+    obtuse divisions. Fertile pinn&aelig; on separate fronds, which are contracted and covered

+    <p>Each fertile frond springs up at first outside the sterile ones, but is soon
+    surrounded and overtopped by them and finds itself in the center of a charming circle
+    of green leaves curving gracefully outwards. In a short time, however, it withers and
+    hangs down or falls to the ground. The large, conspicuous clusters of cinnamon ferns
+    give picturesqueness to many a moist, hillside pasture and swampy woodyard. In its
+    crosier stage it is wrapped in wool, which falls away as the fronds expand, but
+    leaves, at the base of each pinna, a tiny tuft, as if to mark its identity.</p>

+    <p>[Illustration: Cinnamon Fern, var. <i>incisa</i> (Maine)]</p>
+    <p>Many people in the country call the cinnamon fern the "buckhorn brake," and eat
+    with relish the tender part which they find deep within the crown at the base of the
+    unfolding fronds. This is known as the "heart of Osmund." The fern, itself, with its
+    tall, recurving leaves makes a beautiful ornament for the shady lawn, and like the
+    interrupted fern is easy to cultivate. The spores of all the <i>osmundas</i> are
+    green, and need to germinate quickly or they lose their vitality. Common in low and
+    swampy grounds in eastern North America and South America and Japan. May. Some think
+    it was this species which was coupled with the serpent in the old rhyme,</p>

+    <p>[Illustration: Climbing Fern. <i>Lygodium palmatum</i>]</p>
+    <p>Fifty years ago this beautiful fern was more common than at present. There was a
+    considerable colony in a low, alluvial meadow thicket at North Hadley, Mass., not far
+    from Mt. Toby, where we collected it freely in 1872. Many used to decorate their
+    homes with its handsome sprays, draping it gracefully over mirrors and pictures. It
+    was known locally as the Hartford fern. Greedy spoilers ruthlessly robbed its
+    colonies and it became scarce, at least in the Mt. Toby region. In Connecticut a law
+    was enacted in 1867 for its protection and with good results. But as Mr. C.A.
+    Weatherby states in the American Fern Journal (Vol. II, No. 4), the encroachments of
+    tillage (mainly of tobacco, which likes the same soil), are forcing it from its
+    cherished haunts, thus jeopardizing its survival. Doubtless an aggressive agriculture
+    is in part responsible for its scarcity in the more northern locality. It is still
+    found here and there in New England, New York and New Jersey; also in Kentucky,
+    Tennessee and Florida, but is nowhere common. The fertile portion dies when the
+    spores mature, but the sterile frondlets remain green through the winter. A handsome
+    species for the fernery in the house or out of doors.</p>

+    <p>EATON, DANIEL CADY. Born at Gratiot, Mich., September 12, 1834. His grandfather
+    was Amos Eaton, noted botanist and author. Studied botany under his friend, Prof. Asa
+    Gray, who had studied with Prof. John Torrey, who in turn was a pupil of Amos Eaton.
+    Daniel C. was professor of botany in Yale College, for more than thirty years. A man
+    of graceful and winsome personality, an authority on ferns, and widely known by his
+    writings. His masterpiece was "The Ferns of North America" in two large, quarto
+    volumes, beautifully illustrated. He died June 29, 1895.</p>
+    <p>CLUTE, WILLARD NELSON. Born at Painted Post, N.Y., February 26, 1869. Education
+    informal; common schools, university lectures and private study. Manifested early a
+    keen interest in birds and flowers. Was founder and first president of the American
+    Fern Society. Collected in Jamaica more than three hundred species of ferns. Has
+    written extensively on the ferns and their allies, besides publishing several
+    standard volumes. His great distinction is in founding and editing the <i>Fern
+    Bulletin</i> through its twenty volumes, when he combined this publication with
+    <i>The American Botanist</i>, which is now on its twenty-eighth volume, the whole a
+    prodigious achievement of great scientific value.</p>

+    DODGE]</p>
+    <p>UNDERWOOD, LUCIUS MARCUS. Born at New Woodstock, N.Y., October 26, 1853. Spent
+    early life on a farm. Was graduated from Syracuse University in 1877. After teaching
+    several years in his alma mater and elsewhere, he became Professor of Botany in
+    Columbia University. He contributed numerous articles to the <i>Torrey Bulletin</i>,
+    <i>Fern Bulletin</i>, and other scientific journals. His scholarly book, "Our Native
+    Ferns and Their Allies," continued unexcelled through six editions. He died November
+    16, 1907.</p>
+    <p>DAVENPORT, GEO. EDWARD. Born in Boston, August 3, 1833. A promoter and officer of
+    the Middlesex Institute. An accurate and diligent student of the ferns, his numerous
+    articles were published in the <i>Fern Bulletin</i>, in the <i>Torrey Bulletin</i>,
+    <i>Rhodora</i>, and in separate monographs. He was a leading authority on the
+    pteridophyta, and collected a large and choice herbarium of the native ferns, which
+    he donated to the Massachusetts Horticultural Society. By his gentle manners and
+    kindly spirit he won many friends, all of whom were proud to recognize his
+    distinguished ability. He cultivated many of our rare native ferns in his Fellsway
+    home, at Medford, Mass., and freely gave specimens to his friends. He died suddenly
+    of heart failure, November 29, 1907.</p>
+    <p>WATERS, CAMPBELL EASTER. Born in Baltimore County, Md., September 14, 1872. Was
+    graduated at Johns Hopkins University in 1895. Ph.D. in 1899. Was for a time a close
+    student of ferns, and issued his notable book, "Ferns," in 1903, containing his
+    "Analytical Key Based on the Stipes." A chemist by profession, he has pursued that
+    branch of science for the last eighteen years. His address is Bureau of Standards,
+    Washington, D.C.</p>
+    <p>MAXON, WILLIAM RALPH. Born at Oneida, N.Y., February 27, 1877. Was graduated at
+    Syracuse University in 1898. Began as aid in cryptogamic botany, United States
+    National Herbarium, 1899, and is now associate curator of the same. Has specialized
+    in scientific work on the pteridophyta, distinguishing himself by the excellence as
+    well as by the large number of his publications, the more important being "Studies of
+    Tropical American Ferns," Nos. 1 to 6. The <i>Fern Bulletin</i>, <i>Torrey
+    Bulletin</i>, <i>American Fern Journal</i>, <i>Fernwort Papers</i>, et al., have
+    profited from his expert and up-to-date knowledge. He is president of the American
+    Fern Society.</p>
+    <p>PARSONS, FRANCES THEODORA. Born in New York, December 5, 1861. <i>N&eacute;e</i> Smith.
+    Married Commander William Starr Dana of the United States Navy, who was lost at sea.
+    As Mrs. Dana, she published, "How to Know the Wild Flowers," in 1893, and within ten
+    years more than seventy thousand copies of the book had been sold. "According to
+    Season" appeared in 1894. In February, 1896, she married Prof. James Russell Parsons,
+    treasurer of the University of the State of New York. In 1899 she published, "How to
+    Know the Ferns." She combined a thorough knowledge of her subject with an easy and
+    graceful style.</p>
+    <p>DODGE, RAYNAL. Born at Newburyport, Mass., September 9, 1844. Civil War veteran.
+    Wounded at Port Hudson, June 28, 1863. A machinist by trade. A careful observer and
+    student of nature, he discovered <i>Aspidium simulatum</i> at Follymill, Seabrook,
+    N.H., in 1880. (Whittier's "My Playmate," verse 9.) He discovered also the hybrid
+    <i>Aspidium cristatum &times; Marginale</i>. He published his little book, "Ferns and Fern
+    Allies of New England," in 1896. Died October 20, 1918.</p>
+    <p>EATON, ALVAH AUGUSTUS. Born at Seabrook, N.H., November 20, 1865. Studied at the
+    Putnam School in Newburyport, but was largely self-educated. He took up teaching for
+    several years, spending three years in California. Returning East, he became a
+    florist and began to write for various fern journals, giving special attention to the
+    fern allies. He prepared the genera <i>Equisetum</i> and <i>Isoetes</i> for the
+    seventh edition of "Gray's Manual." He proved the keenness of his observing powers by
+    discovering several ferns new to the United States. Died at his home in North Easton,
+    Mass., September 29, 1908.</p>
+    <p>WILLIAMSON, JOHN. Born in Abernathy, Scotland, about the year 1838. He came to
+    Louisville, Ky., to live in 1866. A wood-carver by trade, he could work skillfully in
+    wood or metal, and after a time established a brass foundry. His friend, George E.
+    Davenport, writes of him: "He caught as by some divine gift or inspiration the
+    innermost life and feelings of the wild flowers and ferns, and his marvelously
+    accurate needle transfixed them with revivifying power on paper or metal." His "Ferns
+    of Kentucky," issued in 1878, was the first handbook on ferns published in the United
+    States. He died June 17, 1884, in the mountains of West Virginia, whither he had gone
+    for his health.</p>

+     id="meaningof"
+     name="meaningof">NOTE</a></h4>
+    <p>The student should have some idea of the terms <i>genus</i>, <i>species</i> and
+    <i>variety</i>, although they are not capable of exact definition.</p>
+    <p>A <i>species</i>, or kind, is in botany the unit of classification. It embraces
+    all such individuals as may have originated in a common stock. Such individuals bear
+    an essential resemblance to each other, as well as to their common parent in all
+    their parts. E.g., the Cinnamon fern is a kind or species of fern with the fronds
+    evidently of one kind, and of a common origin, and all producing individuals of their
+    own kind by their spores or rootstocks. When such individuals differ perceptibly from
+    the type in the shape of the pinn&aelig;, or the cutting of the fronds, we have
+    <i>varieties</i> as <i>frond&ograve;sum</i>, <i>inc&igrave;sum</i>, etc. Or if the difference is
+    less striking the word <i>form</i> is used instead of variety, but in any given case
+    opinions may differ in respect to the more fitting term.</p>
+    <p>A <i>genus</i> is an assemblage of species closely related to each other, and
+    having more points of resemblance than of difference; e.g., the royal fern, the
+    cinnamon fern, and the interrupted fern are alike in having similar spore cases borne
+    in a somewhat similar manner on the fronds, and forming the genus <i>Osmunda</i>. In
+    like manner certain members of the clover group--red, white, yellow, etc., make up
+    the genus <i>Trifolium</i>.</p>
+    <p>Thus individuals are grouped into species and species are associated into genera,
+    and the two groups are united to give each fern or plant its true name, the generic
+    name being qualified by that of the species; as in the cinnamon fern <i>Osm&uacute;nda</i>
+    (genus), <i>cinnam&ograve;mea</i> (species).</p>

+THE PETRIFIED FERN
+
+  In a valley, centuries ago,
+  Grew a little fern-leaf green and slender,
+  Veining delicate and fibers tender,
+  Waving when the wind crept down so low;
+  Rushes tall and moss and grass grew round it,
+  Playful sunbeams darted in and found it,
+  Drops of dew stole down by night and crowned it.
+  But no foot of man e'er came that way--
+  Earth was young and keeping holiday.
+
+  Monster fishes swam the silent main,
+  Stately forests waved their giant branches,
+  Mountains hurled their snowy avalanches,
+  Mammoth creatures stalked across the plain,
+  Nature reveled in grand mysteries;
+  But the little fern was not of these,
+  Did not slumber with the hills and trees,
+  Only grew and waved its wild, sweet way;
+  No one came to note it day by day.
+
+  Earth, one time, put on a frolic mood,
+  Heaved the rocks and changed the mighty motion
+  Of the deep, strong currents of the ocean;
+  Moved the plain and shook the haughty wood,
+  Crushed the little fern in soft, moist clay,
+  Covered it and hid it safe away.
+  Oh, the long, long centuries since that day!
+  Oh, the changes! Oh, life's bitter cost!
+  Since the useless little fern was lost.
+
+  Useless? Lost? There came a thoughtful man
+  Searching Nature's secrets far and deep;
+  From a fissure in a rocky steep
+  He withdrew a stone o'er which there ran
+  Fairy pencilings, a quaint design,
+  Leafage, veining, fibers clear and fine,
+  And the fern's life lay in every line!
+  So, I think, God hides some souls away,
+  Sweetly to surprise us the last day!--M.B. BRANCH.

+collection are in the public domain in the United States.  If an
+individual work is in the public domain in the United States and you are

+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed.  Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work.  You can easily comply with the terms of this agreement by

+
+1.D.  The copyright laws of the place where you are located also govern
+what you can do with this work.  Copyright laws in most countries are in

+before downloading, copying, displaying, performing, distributing or

+Gutenberg-tm work.  The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.

+
+1.E.1.  The following sentence, with active links to, or other immediate

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:

+
+1.E.2.  If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges.  If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the

+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.

+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form.  However, if you provide access to or

+form.  Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.

+     Project Gutenberg Literary Archive Foundation.  Royalty payments
+     must be paid within 60 days following each date on which you

+     address specified in Section 4, "Information about donations to
+     the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+     you in writing (or by e-mail) within 30 days of receipt that s/he
+     does not agree to the terms of the full Project Gutenberg-tm
+     License.  You must require such a user to return or
+     destroy all copies of the works possessed in a physical medium
+     and discontinue all use of and all access to other copies of
+     Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+     money paid for a work or a replacement copy, if a defect in the

+Hart, the owner of the Project Gutenberg-tm trademark.  Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1.  Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection.  Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2.  LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees.  YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3.  YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3.  LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from.  If you
+received the work on a physical medium, you must return the medium with
+your written explanation.  The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund.  If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund.  If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4.  Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5.  Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law.  The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6.  INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section  2.  Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers.  It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come.  In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.
+
+
+Section 3.  Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service.  The Foundation's EIN or federal tax identification
+number is 64-6221541.  Its 501(c)(3) letter is posted at
+https://pglaf.org/fundraising.  Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations.  Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org.  Email contact links and up to date contact
+information can be found at the Foundation's web site and official
+page at https://pglaf.org
+
+For additional contact information:
+     Dr. Gregory B. Newby
+     Chief Executive and Director
+     gbnewby@pglaf.org
+
+Section 4.  Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment.  Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States.  Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements.  We do not solicit donations in locations
+where we have not received written confirmation of compliance.  To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States.  U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses.  Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations.  To donate, please visit: https://pglaf.org/donate
+
+
+Section 5.  General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone.  For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included.  Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Each eBook is in a subdirectory of the same number as the eBook's
+eBook number, often in several formats including plain vanilla ASCII,
+compressed (zipped), HTML and others.
+
+Corrected EDITIONS of our eBooks replace the old file and take over
+the old filename and etext number.  The replaced older file is renamed.
+VERSIONS based on separate sources are treated as new eBooks receiving
+new filenames and etext numbers.
+
+Most people start at our Web site which has the main PG search facility:
+
+     https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
+
+EBooks posted prior to November 2003, with eBook numbers BELOW #10000,
+are filed in directories based on their release date.  If you want to
+download any of these eBooks directly, rather than using the regular
+search system you may utilize the following addresses and just
+download by the etext year.
+
+     https://www.gutenberg.org/etext06
+
+    (Or /etext 05, 04, 03, 02, 01, 00, 99,
+     98, 97, 96, 95, 94, 93, 92, 92, 91 or 90)
+
+EBooks posted since November 2003, with etext numbers OVER #10000, are
+filed in a different way.  The year of a release date is no longer part
+of the directory path.  The path is based on the etext number (which is
+identical to the filename).  The path to the file is made up of single
+digits corresponding to all but the last digit in the filename.  For
+example an eBook of filename 10234 would be found at:
+
+     https://www.gutenberg.org/1/0/2/3/10234
+
+or filename 24689 would be found at:
+     https://www.gutenberg.org/2/4/6/8/24689
+
+An alternative method of locating eBooks:
