+PREFACE
+
+
+In this little book I have given the history of those inventions which
+are most useful to man in his daily life. I have told the story of the
+Match, the Stove, the Lamp, the Forge, the Steam-Engine, the Plow, the
+Reaper, the Mill, the Loom, the House, the Carriage, the Boat, the
+Clock, the Book, and the Message. From the history of these inventions
+we learn how man became the master of the world of nature around him,
+how he brought fire and air and earth and water under his control and
+compelled them to do his will and his work. When we trace the growth of
+these inventions we at the same time trace the course of human progress.
+These stories, therefore, are stories of human progress; they are
+chapters in the history of civilization.
+
+And they are chapters which have not hitherto been brought together in
+one book. Monographs on most of the subjects included in this book have
+appeared, and excellent books about modern inventions have been written,
+but as far as I know, this is the first time the evolution of these
+useful inventions has been fully traced in a single volume.
+
+While preparing the stories I have received many courtesies from
+officers in the Library of Congress and from those of the National
+Museum.

+A FOREWORD[1]
+
+
+These stories of useful inventions are chapters in the history of
+civilization and this little book is a book of history. Now we are told
+by Herodotus, one of the oldest and greatest of historians, that when
+the writer of history records an event he should state the _time_ and
+the _place_ of its happening. In some kinds of history--in the history
+of the world's wars, for example, or in the history of its
+politics--this is strictly true. When we are reading of the battle of
+Bunker Hill we should be told precisely when and where the battle was
+fought, and in an account of the Declaration of Independence the time
+and place of the declaration should be given. But in the history of
+inventions we cannot always be precise as to dates and places. Of course
+it cannot be told when the first plow or the first loom or the first
+clock was made. Inventions like these had their origin far back in the
+earliest ages when there was no such person as a historian. And when we
+come to the history of inventions in more recent times the historian is
+still sometimes unable to discover the precise time and place of an
+invention.
+
+It is in the nature of things that the origin of an invention should be
+surrounded by uncertainty and doubt. An invention, as we shall see
+presently, is nearly always a response to a certain want. The world
+wants something and it promises a rich reward to one who will furnish
+the desired thing. The inventor, recognizing the want, sets to work to
+make the thing, but he conducts his experiments in secret, for the
+reason that he does not want another to steal his ideas and get ahead of
+him. We can see that this is true in respect to the flying machine. The
+first experiments with the flying machine were conducted in secret in
+out of the way places and pains were taken that the public should know
+as little as possible about the new machine and about the results of the
+experiments. The history of the flying machine will of course have to be
+written, but because of the secrecy and mystery which surrounded the
+beginnings of the invention it will be extremely difficult for the
+future historian to tell precisely when the first flying machine was
+invented or to name the inventor. If it is so difficult to get the facts
+as to the origin of an invention in our own time, how much more
+difficult it is to clear away the mystery and doubt which surround the
+beginnings of an invention in an age long past!
+
+In a history of inventions, then, the historian cannot be precise in
+respect to dates and places. Fortunately this is not a cause for deep
+regret. It is not a great loss to truth that we cannot know precisely
+when the first book was printed, nor does it make much difference
+whether that book was printed in Holland or in Germany. In giving an
+account of an invention we may be content to treat the matter of time
+and place broadly, for the story is apt to carry us through a stretch of
+years that defies computation, a stretch that is immensely longer than
+the life of any nation. For our purpose these millenniums, these long
+stretches of time, may be thought of as being divided into three great
+periods, namely: the _primitive_, the _ancient_, and the _modern_
+period. Even a division so broad as this is not satisfactory, for in the
+progress of their inventions all countries have not kept equal step with
+the march of time. In some things ancient Greece was modern, while in
+most things modern Alaska is primitive and modern China is ancient.
+Nevertheless it will be convenient at times in this book to speak of the
+_primitive_, the _ancient_ and the _modern_ periods, and it will be
+useful to regard the _primitive_ period as beginning with the coming of
+man on earth and extending to the year 5000 B. C.; the _ancient_ period
+may be thought of as beginning with the year 5000 B. C. and ending with
+the year 476 A. D., leaving for the _modern_ period the years that have
+passed since 476 A. D.
+
+In tracing the growth of an invention the periods indicated above can
+serve as a time-guide only for those parts of the world where the course
+of civilization has taken its way, for invention and civilization have
+traveled the same road. The region of the world's most advanced
+civilization includes the lands bordering on the Mediterranean Sea,
+Central and Northern Europe, the British Isles, North America, South
+America and Australia. It is within this region that we shall follow the
+development of whatever invention is under consideration. When speaking
+of the first forms of an invention, however, it will sometimes be
+necessary, when an illustration is desired, to draw upon the experience
+of people who are outside of the wall of civilization. The reason for
+going outside is plain. The first and simplest forms of the useful
+inventions have utterly perished in civilized countries, but they still
+exist among savage and barbarous peoples and it is among such peoples
+that the first forms must be studied. Thus in the story of the clock,
+we must go to a far-off peninsula of Southern Asia (p. 190) for an
+illustration of the beginning of our modern timepiece. Such a departure
+from the beaten track of civilization does not spoil the story, for as a
+rule, the rude forms of inventions found among the lowest races of
+to-day are precisely the same forms that were in use among the Egyptians
+and Greeks when they were in their lowest state.
+
+When studying the history of an invention there are two facts or
+principles which should ever be borne in mind. The first principle is
+this: _Necessity is the mother of invention._ This principle was touched
+upon when it was said that an invention appears as a response to a want.
+When the world wants an invention it usually gets it and makes the most
+of it, but it will have nothing to do with an invention it does not
+want. The steam-engine was invented two thousand years ago (p. 55) but
+the world then had no work for steam to do, so the invention attracted
+little attention and came to naught. About two hundred years ago,
+however, man did want the services of steam and inventors were not long
+in supplying the engine that was needed. About a hundred years ago the
+broad prairie lands of the United States began to be tilled but it was
+soon found that the vast areas could not be plowed and that the immense
+crops could not be harvested by the old methods. So improvements upon
+the plow and the reaper began to be made and in time the steam gang-plow
+and the complete harvester were invented. When the locomotive first came
+into use a simple handbrake was used to stop the slow-going trains, but
+as the size and the speed of trains increased the handbrake became more
+and more unsatisfactory. Sometimes a train would run as much as a half
+mile beyond a station before it could be stopped and then when "backed"
+it would again pass beyond the station. The problem of stopping the
+train promptly became fully as important as starting it. The problem was
+solved by the invention of the air-brake. And thus it has been with all
+the inventions which surround us: necessity has been the mother of them
+all.
+
+The other principle is that a mechanical invention is a _growth_, or, to
+state the truth in another way, an invention nearly always is simply an
+improvement upon a previous invention. The loom, for example, was not
+invented by a particular person at a particular time; it did not spring
+into existence in a day with all its parts perfected; it _grew_, century
+by century, piece by piece. In the stories which will follow the steps
+in the growth of an invention are shown in the illustrations. These
+pictures are not for amusement but for study. As you read, examine them
+carefully and they will teach you quite as much about the growth of the
+invention as you can be taught by words.

+
+
+
+
+THE MATCH
+
+
+Did you ever think how great and how many are the blessings of fire? Try
+to think of a world without fire. Suppose we should wake up some bitter
+cold morning and find that all the fires in the world were out, and that
+there was no way of rekindling them; that the art of kindling a fire had
+been lost. In such a plight we should all soon be shivering with the
+cold, for our stoves and furnaces could give us no warmth; we should all
+soon be hungry, for we could not cook our food; we should all soon be
+idle, for engines could not draw trains, wheels of factories could not
+turn, and trade and commerce would come to a standstill; at night we
+would grope in darkness, for we could use neither lamp nor gas nor
+electric light. It is easy to see that without fire, whether for light
+or heat, the life of man would be most wretched.
+
+There never was a time when the world was without fire, but there was a
+time when men did not know how to kindle fire; and after they learned
+how to kindle one, it was a long, long time before they learned how to
+kindle one easily. In these days we can kindle a fire without any
+trouble, because we can easily get a match; but we must remember that
+the match is one of the most wonderful things in the world, and that it
+took men thousands of years to learn how to make one. Let us learn the
+history of this familiar little object, the match.
+
+Fire was first given to man by nature itself. When a forest is set on
+fire by cinders from a neighboring volcano, or when a tree is set ablaze
+by a thunderbolt, we may say that nature strikes a match. In the early
+history of the world, nature had to kindle all the fires, for man by his
+own effort was unable to produce a spark. The first method, then, of
+getting fire for use was to light sticks of wood at a flame kindled by
+nature--by a volcano, perhaps, or by a stroke of lightning. These
+firebrands (Fig. 1) were carried to the home and used in kindling the
+fires there. The fire secured in this way was carefully guarded and was
+kept burning as long as possible. But the flame, however faithfully
+watched, would sometimes be extinguished. A sudden gust of wind or a
+sudden shower would put it out. Then a new firebrand would have to be
+secured, and this often meant a long journey and a deal of trouble.
+
+[Illustration: FIG. 1.--GETTING A MATCH FROM NATURE.]
+
+[Illustration: FIG. 2.--PRIMITIVE FIRE-MAKING. THE STICK-AND-GROOVE
+METHOD.]
+
+In the course of time a man somewhere in the world hit upon a plan of
+kindling a fire without having any fire to begin with; that is to say,
+he hit upon a plan of producing a fire by _artificial_ means. He knew
+that by rubbing his hands together very hard and very fast he could make
+them very warm. By trial he learned that by rubbing two pieces of dry
+wood together he could make _them_ very warm. Then he asked himself the
+question: Can a fire be kindled by rubbing two pieces of wood together,
+if they are rubbed hard enough? He placed upon the ground a piece of
+perfectly dry wood (Fig. 2) and rubbed this with the end of a stick
+until a groove was made. In the groove a fine dust of wood--a kind of
+sawdust--was made by the rubbing. He went on rubbing hard and fast,
+and, behold, the dust in the groove began to glow! He placed some dry
+grass upon the embers and blew upon them with his breath, and the grass
+burst into a flame.[2] Here for the first time a man kindled a fire for
+himself. He had invented the match, the greatest invention, perhaps, in
+the history of the world.
+
+[Illustration: FIG. 3.--THE FIRE DRILL.
+
+(Simple Form.)]
+
+The stick-and-groove method--as we may call it--of getting a flame was
+much better than guarding fire and carrying it from place to place; yet
+it was, nevertheless, a very clumsy method. The wood used had to be
+perfectly dry, and the rubbing required a vast amount of work and
+patience. Sometimes it would take hours to produce the spark. After a
+while--and doubtless it was a very long while--it was found that it was
+better to keep the end of the stick in one spot and twirl it (Fig. 3)
+than it was to plow to and fro with it. The twirling motion made a hole
+in which the heat produced by the friction was confined in a small
+space. At first the drilling was done by twirling the stick between the
+palms of the hands, but this made the hands too hot for comfort, and
+the fire-makers learned to do the twirling with a cord or thong[3]
+wrapped around the stick (Fig. 4). You see, the upper end of the stick
+which serves as a drill turns in a cavity in a mouthpiece which the
+operator holds between his teeth. If you should undertake to use a
+fire-drill of this kind, it is likely that your jaws would be painfully
+jarred.
+
+[Illustration: FIG. 4.--FIRE DRILL.
+
+(Improved Form.)]
+
+By both the methods described above, the fire was obtained by rubbing or
+_friction_. The friction method seems to have been used by all primitive
+peoples, and it is still in use among savages in various parts of the
+world.
+
+[Illustration: FIG. 5.--STRIKING FIRE.]
+
+[Illustration: FIG. 6.--TINDER BOX, FLINT, STEEL, AND SULPHUR-TIPPED
+SPLINTERS.]
+
+The second step in fire-making was taken when it was discovered that a
+spark can be made by striking together a stone and a piece of iron ore.
+Strike a piece of flint against a piece of iron ore known as pyrites, or
+fire-stone, and you will make sparks fly. (Fig. 5.) Let these sparks fall
+into small pieces of dried moss or powdered charcoal, and the _tinder_,
+as the moss or the charcoal is called, will catch fire. It will glow,
+but it will not blaze. Now hold a dry splinter in the glowing tinder,
+and fan or blow with the breath and the splinter will burst into a
+flame. If you will tip your splinter with sulphur before you place it in
+the burning tinder, you will get a flame at once. This was the
+strike-a-light, or _percussion_, method of making a fire. It followed
+the friction method, and was a great improvement upon it because it took
+less work and a shorter time to get a blaze. The regular outfit for
+fire-making with the strike-a-light consisted of a tinder-box, a piece
+of steel, a piece of flint, and some splinters tipped with sulphur (Fig.
+6). The flint and steel were struck together, and the sparks thus made
+fell into the tinder and made it glow. A splinter was applied as quickly
+as possible to the tinder, and when a flame was produced the candle
+which rested in the socket on the tinder-box was lighted. As soon as the
+splinter was lighted the cover was replaced on the tinder-box, so as to
+smother the glowing tinder and save it for another time.
+
+The strike-a-light method was discovered many thousands of years ago,
+and it has been used by nearly all the civilized nations of the
+world.[4] And it has not been so very long since this method was laid
+aside. There are many people now living who remember when the flint and
+steel and tinder-box were in use in almost every household.
+
+About three hundred years ago a third method of producing fire was
+discovered. If you should drop a small quantity of sulphuric acid into a
+mixture of chlorate of potash and sugar, you would produce a bright
+flame. Here was a hint for a new way of making a fire; and a thoughtful
+man in Vienna, in the seventeenth century, profited by the hint. He took
+one of the sulphur-tipped splinters which he was accustomed to use with
+his tinder-box, and dipped it into sulphuric acid, and then applied it
+to a mixture of chlorate of potash and sugar. The splinter caught fire
+and burned with a blaze. Here was neither friction nor percussion. The
+chemical substances were simply brought together, and they caught fire
+of themselves; that is to say, they caught fire by _chemical_ action.
+
+The discovery made by the Vienna man led to a new kind of match--the
+chemical match. A practical outfit for fire-making now consisted of a
+bottle of sulphuric acid (vitriol) and a bundle of splints tipped with
+sulphur, chlorate of potash, and sugar. Matches of this kind were very
+expensive, costing as much as five dollars a hundred; besides, they were
+very unsatisfactory. Often when the match was dipped into the acid it
+would not catch fire, but would smolder and sputter and throw the acid
+about and spoil both the clothes and the temper. These dip-splint
+matches were used in the eighteenth century by those who liked them and
+could afford to buy them. They did not, however, drive out the old
+strike-a-light and tinder-box.
+
+In the nineteenth century--the century in which so many wonderful things
+were done--the fourth step in the development of the match was taken. In
+1827, John Walker, a druggist in a small English town, tipped a splint
+with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it
+on sandpaper, and it burst into flame. The druggist had discovered the
+first _friction-chemical_ match, the kind we use to-day. It is called
+friction-chemical because it is made by mixing certain chemicals
+together and rubbing them. Although Walker's match did not require the
+bottle of acid, nevertheless it was not a good one. It could be lighted
+only by hard rubbing, and it sputtered and threw fire in all directions.
+In a few years, however, phosphorus was substituted on the tip for
+antimony, and the change worked wonders. The match could now be lighted
+with very little rubbing, and it was no longer necessary to have
+sandpaper upon which to rub it. It would ignite when rubbed on any dry
+surface, and there was no longer any sputtering. This was the
+_phosphorus_ match, the match with which we are so familiar.
+
+After the invention of the easily-lighted phosphorus match there was no
+longer use for the dip-splint or the strike-a-light. The old methods of
+getting a blaze were gradually laid aside and forgotten. The first
+phosphorus matches were sold at twenty-five cents a block--a block (Fig.
+7) containing a hundred and forty-four matches. They were used by few.
+Now a hundred matches can be bought for a cent. It is said that in the
+United States we use about 150,000,000,000 matches a year. This, on an
+average, is about five matches a day for each person.
+
+[Illustration: FIG. 7.--A "BLOCK" OF MATCHES.]
+
+There is one thing against the phosphorus match: it ignites too easily.
+If one is left on the floor, it may be ignited by stepping upon it, or
+by something falling upon it. We may step on a phosphorus match
+unawares, light it, leave it burning, and thus set the house on fire.
+Mice often have caused fires by gnawing the phosphorus matches and
+igniting them. In one city thirty destructive fires were caused in one
+year by mice lighting matches.
+
+[Illustration: FIG. 8.--A BOX OF MODERN SAFETY MATCHES.]
+
+To avoid accident by matches, the _safety match_ (Fig. 8) has recently
+been invented. The safety match does not contain phosphorus. The
+phosphorus is mixed with fine sand and glued to the side of the box in
+which the matches are sold. The safety match, therefore, cannot be
+lighted unless it is rubbed on the phosphorus on the outside of the box.
+It is so much better than the old kind of phosphorus match that it is
+driving the latter out of the market. Indeed, in some places it is
+forbidden by law to sell any kind of match but the safety match.
+
+The invention of the safety match is the last step in the long history
+of fire-making. The first match was lighted by rubbing, and the match of
+our own time is lighted by rubbing; yet what a difference there is
+between the two! With the plowing-stick or fire-drill it took strength
+and time and skill to get a blaze; with the safety match an awkward
+little child can kindle a fire in a second.
+
+And how long it has taken to make the match as good as it is! The
+steam-engine, the telegraph, the telephone, and the electric light were
+all in use before the simple little safety match.
+
+
+FOOTNOTES:
+
+[2] Mr. Walter Hough of the National Museum, himself a wizard in the art
+of fire-making, tells me that a blaze cannot be produced simply by
+rubbing sticks together. All that can be done by rubbing is to make them
+glow.

+
+[4] The ancient Greeks used a burning-glass or -lens for kindling fire.
+The lens focused the sun's rays upon a substance that would burn easily
+and set it afire. The burning-glass was not connected in any way with
+the development of the match.
+
+
+
+
+THE STOVE
+
+
+From the story of the match you have learned how man through long ages
+of experience gradually mastered the art of making a fire easily and
+quickly. In this chapter, and in several which are to follow, we shall
+have the history of those inventions which have enabled man to make the
+best use of fire. Since the first and greatest use of fire is to cook
+food and keep the body warm, our account of the inventions connected
+with the use of fire may best begin with the story of the stove.
+
+The most important uses of fire were taught by fire itself. As the
+primitive man stood near the flames of the burning tree and felt their
+pleasant glow, he learned that fire may add to bodily comfort; and when
+the flames swept through a forest and overtook a deer and baked it, he
+learned that fire might be used to improve the quality of his food. The
+hint was not lost. He took a burning torch to his cave or hut and
+kindled a fire on his floor of earth. His dwelling filled with smoke,
+but he could endure the discomfort for the sake of the fire's warmth,
+and for the sake of the toothsomeness of the cooked meats. After a time
+a hole was made in the roof of the hut, and through this hole the smoke
+passed out. Here was the first stove. The primitive stove was the entire
+house; the floor was the fireplace and the hole in the roof was the
+chimney (Fig. 1). The word "stove" originally meant "a heated room." So
+that if we should say that at first people lived in their stoves, we
+should say that which is literally true.
+
+[Illustration: FIG. 1.--THE PRIMITIVE STOVE.]
+
+Early inventions in cooking consisted in simple devices for applying
+flame directly to the thing which was to be cooked. The first roasting
+was doubtless done by fastening the flesh to a pole placed in a
+horizontal position above the fire and supported as is shown in Figure
+2.[5] The horizontal bar called a spit was originally of wood, but after
+man had learned to work in metals an iron bar was used. When one side of
+the flesh was roasted the spit was turned and the other side was exposed
+to the flames. The spit of the primitive age was the parent of the
+modern grill and broiler.
+
+[Illustration: FIG. 2.--PRIMITIVE COOKING.]
+
+Food was first boiled in a hole in the ground. A hole was filled with
+water into which heated stones were thrown. The stones, by giving off
+their heat, caused the water to boil in a very short time. After the
+art of making vessels of clay was learned, food was boiled in earthen
+pots suspended above the fire.
+
+The methods of warming the house and cooking the food which have just
+been described were certainly crude and inconvenient, but it was
+thousands of years before better methods were invented. The long periods
+of savagery and barbarism passed and the period of civilization was
+ushered in, but civilization did not at once bring better stoves.
+Neither the ancient Egyptians nor the ancient Greeks knew how to heat a
+house comfortably and conveniently. All of them used the primitive
+stove--a fire on the floor and a hole in the roof. In the house of an
+ancient Greek there was usually one room which could be heated when
+there was need, and this was called the "black-room" (_atrium_)--black
+from the soot and smoke which escaped from the fire on the floor.
+
+But we must not speak harshly of the ancients because they were slow in
+improving their methods of heating for in truth the modern world has
+not done as well in this direction as might have been expected. In a
+book of travels written only sixty years ago may be found the following
+passage: "In Normandy, where the cold is severe and fire expensive, the
+lace-makers, to keep themselves warm and to save fuel, agree with some
+farmer who has cows in winter quarters to be allowed to carry on their
+work in the society of the cattle. The cows would be tethered in a long
+row on one side of the apartment, and the lace-makers sit on the ground
+on the other side with their feet buried in the straw." Thus the
+lace-makers kept themselves warm by the heat which came from the bodies
+of the cattle; the cows, in other words, served as stoves. This
+barbarous method of heating, was practised in some parts of France less
+than sixty years ago.
+
+[Illustration: FIG. 3.--A ROMAN BRAZIER.]
+
+The ancient peoples around the Mediterranean may be excused for not
+making great progress in the art of heating, for their climate was so
+mild that they seldom had use for fire in the house. Nevertheless there
+was in use among these people an invention which has in the course of
+centuries developed into the stove of to-day. This was the _brazier_, or
+warming-pan (Fig. 3). The brazier was filled with burning charcoal and
+was carried from room to room as it was needed. The unpleasant gases
+which escaped from the charcoal were made less offensive, but not less
+unhealthy, by burning perfumes with the fuel. The brazier has never been
+entirely laid aside. It is still used in Spain and in other warm
+countries where the necessity for fire is rarely felt.
+
+The brazier satisfied the wants of Greece, but the colder climate of
+Rome required something better; and in their efforts to invent something
+better, the ancient Romans made real progress in the art of warming
+their houses. They built a fire-room--called a _hypocaust_--in the
+cellar, and, by means of pipes made of baked clay, they connected the
+hypocaust with different parts of the house (Fig. 4). Heat and smoke
+passed up together through these pipes. The poor ancients, it seems,
+were forever persecuted by smoke. However, after the wood in the
+hypocaust was once well charred, the smoke was not so troublesome. The
+celebrated baths (club-rooms) of ancient Rome were heated by means of
+hypocausts with excellent results. Indeed, the hypocaust had many of the
+features and many of the merits of our modern furnace. Its weak feature
+was that it had no separate pipe to carry away the smoke. But as there
+were no chimneys yet in the world, it is no wonder there was no such

+[Illustration: FIG. 4.--A ROMAN HYPOCAUST.]
+
+The Romans made quite as much progress in the art of cooking as they
+did in the art of heating. Perhaps the world has never seen more skilful
+cooks than those who served in the mansions of the rich during the
+period of the Roman Empire (27 B.C.-476 A.D.). In this period the great
+men at Rome abandoned their plain way of living and became gourmands.
+One of them wished for the neck of a crane, that he might enjoy for a
+longer time his food as it descended. This demand for tempting viands
+developed a race of cooks who were artists in their way. Upon one
+occasion a king called for a certain kind of fish. The fish could not be
+had, but the cook was equal to the emergency. "He cut a large turnip to
+the perfect imitation of the fish desired, and this he fried and
+seasoned so skilfully that his majesty's taste was exquisitely deceived,
+and he praised the root to his guests as an excellent fish." Such
+excellent cooking could not be done on a primitive stove, and along with
+the improvements in the art of cooking, there was a corresponding
+improvement at Rome in the art of stove-making.
+
+When Rome fell (476 A.D.), many of the best features of her civilization
+perished with her. Among the things that were lost to the world were the
+Roman methods of cooking and heating. When the barbarians came in at the
+front door, the cooks fled from the kitchen. The hardy northerners had
+no taste for dainty cooking. Hypocausts ceased to be used, and were no
+longer built. For several hundred years, in all the countries of Europe,
+the fireplace was located, as of old, on the floor in the center of the
+room, while the smoke was allowed to pass out through a hole in the
+roof.
+
+[Illustration: FIG. 5.--A CHIMNEY AND FIREPLACE IN AN OLD ENGLISH
+CASTLE.]
+
+The eleventh century brought a great improvement in the art of heating,
+and the improvement came from England. About the time of the Conquest
+(1066) a great deal of fighting was done on the roofs of English
+fortresses, and the smoke coming up through the hole in the center of
+the roof proved to be troublesome to the soldiers. So the fire was moved
+from the center of the floor to a spot near an outside wall, and an
+opening was made in the wall just above the fire, so that the smoke
+could pass out. Here was the origin of the _chimney_. Projecting from
+the wall above the fire was a hood, which served to direct the smoke to
+the opening. At first the opening for the smoke extended but a few feet
+from the fire, but it was soon found that the further up the wall the
+opening extended the better was the draft. So the chimney was made to
+run diagonally up the wall as far as possible. The next and last step
+in the development of the chimney was to make a recess in the wall as a
+fireplace, and to build a separate structure of masonry--the
+chimney--for the smoke. By the middle of the fourteenth century chimneys
+were usually built in this way (Fig. 5). As the fireplace and chimney
+cleared the house of soot and smoke, they grew in favor rapidly. By the
+end of the fifteenth century they were found in the homes of nearly all
+civilized people.
+
+The open fireplace was always cheerful, and it was comfortable when you
+were close to it; but it did not heat all parts of the room equally.
+That part next to the fireplace might be too warm for comfort, while in
+another part of the room it might be freezing. About the end of the
+fifteenth century efforts were made to distribute heat throughout the
+room more evenly. These efforts led to the invention of the modern
+stove. We have learned that the origin of the stove is to be sought in
+the ancient brazier. In the middle ages the brazier in France took on a
+new form. Here was a fire-box (Fig. 6) with openings at the bottom for
+drafts of air and arrangements at the top for cooking things. This
+French warming-pan (_réchaud_) was the connecting-link between the
+ancient brazier and the modern stove. All it lacked of being a stove was
+a pipe to carry off the smoke, and this was added by a Frenchman named
+Savot, about two hundred years ago. We owe the invention of the chimney
+to England, but for the stove we are indebted to France. The Frenchman
+built an iron fire-box, with openings for drafts, and connected the box
+with the chimney by means of an iron flue or pipe. Here was a _stove_
+which could be placed in the middle of the room, or in any part of the
+room where it was desirable, and which would send out its heat evenly in
+all directions.
+
+[Illustration: FIG. 6.--A STOVE OF THE MIDDLE AGES.]
+
+The first stoves were, of course, clumsy and unsatisfactory; but
+inventors kept working at them, making them better both for cooking and
+for heating. By the middle of the nineteenth century the stove was
+practically what it is to-day (Fig. 7). Stoves proved to be so much
+better than fireplaces, that the latter were gradually replaced in large
+part by the former. Our affection, however, for a blazing fire is
+strong, and it is not likely that the old-fashioned fireplace (Fig. 8)
+will ever entirely disappear.
+
+[Illustration: FIG. 7.--THE MODERN STOVE.]
+
+[Illustration: FIG. 8.--AN OLD-FASHIONED FIREPLACE AND OVEN.]
+
+The French stove just described is intended to heat only one room. If a
+house with a dozen rooms is to be heated, a dozen stoves are necessary.
+About one hundred years ago there began to appear an invention by which
+a house of many rooms could be heated by means of one stove. This
+invention was the _furnace_. Place in the cellar a large stove, and run
+pipes from the stove to the different rooms of the house, and you have a
+furnace (Fig. 9). Doubtless we got our idea of the furnace from the
+Roman hypocaust, although the Roman invention had no special pipe for
+the smoke. The first furnaces sent out only hot air, but in recent years
+steam or hot water is sent out through the pipes to _radiators_, which
+are simply secondary stoves set up in convenient places and at a
+distance from the source of the heat, the furnace in the cellar.
+Furnaces were invented for the purpose of heating large buildings, but
+they are now used in ordinary dwellings.
+
+[Illustration: FIG. 9.--A MODERN FURNACE.]
+
+In its last and most highly developed form, the stove appears not only
+without dust and smoke, but also without even a fire in the cellar. The
+modern _electric_ stove, of course, is meant. Pass a slight current of
+electricity through a piece of platinum wire, and the platinum becomes
+hot. You have made a diminutive electric stove. Increase the strength of
+your current and pass it through something which offers greater
+resistance than the platinum, and you get more heat. The electric stove
+is a new invention, and at present it is too expensive for general use,
+although the number of houses in which it is used is rapidly increasing,
+and in time it may drive out all other kinds of stoves. It will
+certainly drive all of them out if the cost of electricity shall be
+sufficiently reduced; for it is the cleanest, the healthiest, the most
+convenient, and the most easily controlled of stoves.

+
+THE LAMP
+
+
+Next to its usefulness for heating and cooking, the greatest use of fire
+is to furnish light to drive away darkness. Man is not content, like
+birds and brutes, to go to sleep at the setting of the sun. He takes a
+part of the night-time and uses it for work or for travel or for social
+pleasures, or for the improvement of his mind, and in this way adds
+several years to life. He could not do this if he were compelled to
+grope in darkness. When the great source of daylight disappears he must
+make light for himself, for the sources of night-light--the moon and
+stars and aurora borealis and lightning--are not sufficient to satisfy
+his wants. In this chapter we shall follow man in his efforts to conquer
+darkness, and we shall have the story of the lamp.
+
+We may begin the story with an odd but interesting kind of lamp. The
+firefly or lightning-bug which we see so often in the summer nights was
+in the earliest time brought into service and made to shed its light for
+man. Fireflies were imprisoned in a rude box--in the shell of a
+cocoanut, perhaps, or in a gourd--and the light of their bodies was
+allowed to shoot out through the numerous holes made in the box. We
+must not despise the light given out by these tiny creatures. "In the
+mountains of Tijuca," says a traveler, "I have read the finest print by
+the light of one of these natural lamps (fireflies) placed under a
+common glass tumbler (Fig. 1), and with distinctness I could tell the
+hour of the night and discern the very small figures which marked the
+seconds of a little Swiss watch."
+
+[Illustration: FIG. 1.--A FIREFLY LAMP.]
+
+[Illustration: FIG. 2.--A BURNING STICK WAS THE FIRST LAMP.]
+
+Although fireflies have been used here and there by primitive folk, they
+could hardly have been the first lamp. Man's battle with darkness really
+began with the _torch_, which was lighted at the fire in the cave or in
+the wigwam and kept burning for purposes of illumination. A burning
+stick was the first lamp (Fig. 2). The first improvement in the torch
+was made when slivers or splinters of resinous or oily wood were tied
+together and burned. We may regard this as a lamp which is all wick.
+This invention resulted in a fuller and clearer light, and one that
+would burn longer than the single stick. A further improvement came when
+a long piece of wax or fatty substance was wrapped about with leaves.
+This was something like a candle, only the wick (the leaves) was
+outside, and the oily substance which fed the wick was in the center.
+
+In the course of time it was discovered that it was better to smear the
+grease on the _outside_ of the stick, or on the outside of whatever was
+to be burned; that is, that it was better to have the wick _inside_.
+Torches were then made of rope coated with resin or fat, or of sticks or
+splinters smeared with grease; here the stick resembled the wick of the
+candle as we know it to-day, and the coating of fat corresponded to the
+tallow or paraffin. Rude candles made of oiled rope or of sticks smeared
+with fat were invented in primitive times, and they continued to be used
+for thousands of years after men were civilized. In the dark ages--and
+they were dark in more senses than one--torch-makers began to wrap the
+central stick first with flax or hemp and then place around this a thick
+layer of fat. This torch gave a very good light, but about the time of
+Alfred the Great (900 A.D.) another step was taken: the central stick
+was left out altogether, and the thick layer of fat or wax was placed
+directly around the wick of twisted cotton. All that was left of the
+original torch--the stick of wood--was gone. The torch had developed
+into the _candle_ (Fig. 3). The candles of to-day are made of better
+material than those of the olden time, and they are much cheaper; yet in
+principle they do not differ from the candles of a thousand years ago.
+
+[Illustration: FIG. 3.--THE CANDLE.]
+
+[Illustration: FIG. 4.--A SHELL FILLED WITH OIL AND USED AS A LAMP.]
+
+I have given the development of the candle first because its forerunner,
+the torch, was first used for lighting. But it must not be forgotten
+that along with the torch there was used, almost from the beginning,
+another kind of lamp. Almost as soon as men discovered that the melted
+fat of animals would burn easily--and that was certainly very long
+ago--they invented in a rude form the _lamp_ from which the lamp of
+to-day has been evolved. The cavity of a shell (Fig. 4) or of a stone,
+or of the skull of an animal, was filled with melted fat or oil, and a
+wick of flax or other fibrous material was laid upon the edge of the
+vessel. The oil or grease passed up the wick by capillary action,[6] and
+when the end of the wick was lighted it continued to burn as long as
+there were both oil and wick. This was the earliest lamp. As man became
+more civilized, instead of a hollow stone or a skull, an earthen saucer
+or bowl was used. Around the edge of the bowl a gutter or spout was made
+for holding the wick. In the lamp of the ancient Greeks and Romans the
+reservoir which held the oil was closed, although in the center there
+was a hole through which the oil might be poured. Sometimes one of these
+lamps would have several spouts or nozzles. The more wicks a lamp had,
+of course, the more light it would give. There is in the museum at
+Cortona, in Italy, an ancient lamp which has sixteen nozzles. This
+interesting relic (Fig. 5) was used in a pagan temple in Etruria more
+than twenty-five hundred years ago.
+
+[Illustration: FIG. 5.--AN ETRUSCAN LAMP 2500 YEARS OLD.]
+
+[Illustration: FIG. 6.--AN ANCIENT LAMP.]
+
+Lamps such as have just been described were used among the civilized
+peoples of the ancient world, and continued to be used through the
+Middle Ages far into modern times. They were sometimes very costly and
+beautiful (Fig. 6), but they never gave a good light. They sent out an
+unpleasant odor, and they were so smoky that they covered the walls and
+furniture with soot. The candle was in every way better than the ancient
+lamp, and after the invention of wax tapers--candles made of wax--in the
+thirteenth century, lamps were no longer used by those who could afford
+to buy tapers. For ordinary purposes and ordinary people, however, the
+lamp continued to do service, but it was not improved. The eighteenth
+century had nearly passed, and the lamp was still the unsatisfactory,
+disagreeable thing it had always been.
+
+[Illustration: FIG. 7.--AN ARGAND LAMP.]
+
+Late in the eighteenth century the improvement came. In 1783 a man
+named Argand, a Swiss physician residing in London, invented a lamp that
+was far better than any that had ever been made before. What did Argand
+do for the lamp? Examine an ordinary lamp in which coal-oil is burned.
+The _chimney_ protects the flame from sudden gusts of wind and also
+creates a draft of air,[7] just as the fire-chimney creates a draft.
+Argand's lamp (Fig. 7) was the first to have a chimney. Look below the
+chimney and you will see open passages through which air may pass upward
+and find its way to the wick. Notice further that as this draft of air
+passes upward it is so directed that, when the lamp is burning, an extra
+quantity of air plays directly upon the wick. Before Argand, the wick
+received no supply of air. Now notice--and this is very important--that
+the wick of our modern lamp is flat or circular, but _thin_. The air in
+abundance plays upon both sides of the thin wick, and burns it without
+making smoke. Smoke is simply half-burned particles (soot) of a burning
+substance. The particles pass off half-burned because enough air has not
+been supplied. Now Argand, by making the wick thin and by causing plenty
+of air to rush into the flame, caused all the wick to be burned and
+thereby caused it to burn with a white flame.
+
+After the invention of Argand, the art of lamp-making improved by leaps
+and by bounds. More progress was made in twenty years after 1783 than
+had been made in twenty centuries before. New burners were invented, new
+and better oils were used, and better wicks made. But all the new kinds
+of lamps were patterned after the Argand. The lamp you use at home may
+not be a real Argand, but it is doubtless made according to the
+principles of the lamp invented by the Swiss physician in 1783.
+
+Soon after Argand invented his lamp, William Murdock, a Scottish
+inventor, showed the world a new way of lighting a house. It had long
+been known that fat or coal, when heated, gives off a vapor or gas which
+burns with a bright light. Indeed, it is _always_ a gas that burns, and
+not a hard substance. In the candle or in the lamp the flame heats the
+oil which comes up to it through the wick and thus causes the oil to
+give off a gas. It is this gas that burns and gives the light. Now
+Murdock, in 1797, put this principle to a good use. He heated coal in a
+large vessel, and allowed the gas which was driven off to pass through
+mains and tubes to different parts of his house. Wherever he wanted a
+light he let the gas escape at the end of the tube (Fig. 8) in a small
+jet and lighted it. Here was a lamp without a wick. Murdock soon
+extended his gas-pipes to his factories, and lighted them with gas. As
+soon as it was learned how to make gas cheaply, and conduct it safely
+from house to house, whole cities were rescued from darkness by the new
+illuminant. A considerable part of London was lighted by gas in 1815.
+Baltimore was the first city in the United States to be lighted by gas.
+This was in 1821.
+
+[Illustration: FIG. 8.--THE GAS JET.]
+
+[Illustration: FIG. 9.--AN EARLY ARC LAMP.]
+
+The gas-light proved to be so much better than even the best of lamps,
+that in towns and cities almost everybody who could afford to do so laid
+aside the old wick-lamp and burned gas. About 1876, however, a new kind
+of light began to appear. This was the _electric_ light. The powerful
+_arc light_ (Fig. 9), made by the passage of a current of electricity
+between two carbon points, was the first to be invented. This gave as
+much light as a hundred gas-jets or several hundred lamps. Such a light
+was excellent for lighting streets, but its painful glare and its
+sputtering rendered it unfit for use within doors. It was not long,
+however, before an electric light was invented which could be used
+anywhere. This was the famous Edison's _incandescent_ or glow lamp (Fig.
+10), which we see on every hand. Edison's invention is only a few years
+old, yet there are already more than thirty million incandescent lamps
+in use in the United States alone.
+
+[Illustration: FIG. 10.--AN INCANDESCENT ELECTRIC LIGHT.]
+
+The torch, the candle, the lamp, the gas-light, the electric
+light,--these are the steps of the development of the lamp. And how
+marvelous a growth it is! How great the triumph over darkness! In the
+beginning a piece of wood burns with a dull flame, and fills the dingy
+wigwam or cave with soot and smoke; now, at the pressure of a button,
+the house is filled with a light that rivals the light of day, with not
+a particle of smoke or soot or harmful gas. Are there to be further
+triumphs in the art of lighting? Are we to have a light that shall drive
+out the electric light? Only time can tell.

+
+THE FORGE
+
+
+After men had learned how to use fire for cooking and heating and
+lighting they slowly learned how to use it when working with metals. In
+the earliest times metals were not used. For long ages stone was the
+only material that man could fashion and shape to his use. During this
+period, sometimes called the "stone age," weapons were made of stone;
+dishes and cooking utensils were made of stone; and even the poor, rude
+tools of the age were made of stone (Fig. 1).
+
+[Illustration: FIG. 1.--IMPLEMENTS OF THE STONE AGE.]
+
+[Illustration: FIG. 2.--IMPLEMENTS OF THE BRONZE AGE.]
+
+In the course of time man learned how to make his implements and weapons
+of metals as well as of stone. It is generally thought that bronze was
+the first metal to be used and that the "stone age" was followed
+directly by the "bronze age," a period when all utensils, weapons, and
+tools were made of bronze (Fig. 2). It is easy to believe that bronze
+was used before iron, for bronze is made of a mixture of tin and copper
+and these two metals are often found in their pure or natural state.
+Whenever primitive man, therefore, found pieces of pure copper and tin,
+he could take the two metals and by melting them could easily mix them
+and make bronze of them. This bronze he could fashion to his use.
+There is no doubt that he did this at a very early age. In nearly all
+parts of the world there are proofs that in primitive times, many
+articles were made of bronze.
+
+If primitive man were slow to learn the use of iron it was not because
+this metal was scarce, for iron is everywhere. "Wherever, as we go up
+and down, we see a red-colored surface, or a reddish tint upon the solid
+substances of the earth, we see iron--the bank of red clay, the red
+brick, the red paint upon the house wall, the complexion of rosy youth,
+or my lady's ribbon. Even the rosy apple derives its tint from iron
+which it contains."[8] But although iron is so abundant it is seldom
+found in its pure or natural state. It is nearly always mixed with other
+substances, the mixture being known as iron ore. Primitive man could
+find copper and tin in their pure state but the only pure iron he could
+find was the little which fell from heaven in the form of meteors, and
+even this was not perfectly pure for meteoric iron is also mixed
+slightly with other metals.
+
+The iron which lay about primitive man in such abundance was buried and
+locked tightly in an _ore_. To separate the iron from the other
+substances of the ore was by no means an easy thing to do. Iron can best
+be extracted from the ore by putting the ore in a fire and melting out
+the iron. Place some iron ore in a fire and if the fire is hot
+enough--and it must be very hot indeed--the iron will leave the ore and
+will gather into a lump at the bottom of the fire. To separate the iron
+from its ore in this way is to make iron. When and where man first
+learned the secret of making iron is of course unknown. A camp-fire in
+some part of the world may have shown to man the first lump of iron, or
+a forest fire sweeping along and melting ores in its path may have given
+the first hint for the manufacture of iron.
+
+[Illustration: FIG. 3.--THE PRIMITIVE FORGE.]
+
+Iron making at first doubtless consisted in simply melting the ore in an
+open heap of burning wood or charcoal, for charcoal is an excellent fuel
+for smelting (melting) ores. But this open-fire method was wasteful and
+tedious and at a very early date the smelting of the ore was done in a
+rude sort of a furnace. A hole ten or twelve feet deep was dug in the
+side of a hill. In the hole were placed charcoal and iron ore, first a
+layer of charcoal, then a layer of the ore. At the top of the mass there
+was an opening and at the bottom there were several openings. When the
+mass was set on fire the openings produced a good strong draft, the
+charcoal was consumed, and the ore was smelted. The product was a lump
+of _wrought iron_, known as the _bloom_.
+
+[Illustration: FIG. 4.--BELLOWS WORKED BY THE FEET.]
+
+The hillside furnace worked well enough when the wind was favorable, but
+when the wind was unfavorable there was no draft and no iron could be
+made. So ironmakers found a way by which the air could be driven into
+the furnace by artificial means. They invented the _bellows_, a blowing
+apparatus (Fig. 3) which was usually made of goat skins sewed together
+and which was operated either by the hands or by the feet (Fig. 4).
+Sometimes the bellows consisted of a hollow log in which a piston was
+worked up and down (Fig. 5). After the invention of the bellows,
+ironmakers could make their iron whenever and wherever they pleased, for
+they could force air into their furnaces at any time and at any place.
+This rude bellows forcing a draft of air into a half-closed furnace
+filled with a burning mass of charcoal and iron ore was the first form
+of the forge, one of the greatest of all inventions.
+
+[Illustration: FIG. 5.--THE WOODEN BELLOWS.]
+
+With the invention of the forge the stone age gradually passed away and
+the iron age was ushered in. Tools and weapons could now be made of
+iron. And great was the difference between iron tools and stone tools.
+To cut down a tree with a flint hatchet required the labor of a man for
+a month, while to clear a forest with such an implement was an
+impossible task. But the forge gave to man iron for the sharp cutting
+tools, for the ax and knife and chisel and saw. With these he became the
+master of wood and he could now easily cut down trees and build houses
+and make furniture and wagons and boats.
+
+As time went on and man advanced in civilization, iron was found to be
+the most useful of metals. Iron can be shaped into many forms. It can be
+drawn into wire of any desired length or fineness, it may be bent in any
+direction, it may be sharpened, or hardened, or softened, at pleasure.
+"Iron accommodates itself to all our wants and desires and even to our
+caprices. It is equally serviceable to the arts, the sciences, to
+agriculture and war; the same ore furnishes the sword, the plowshare,
+the scythe, the pruning-hook, the needle, the spring of a watch or of a
+carriage, the chisel, the chain, the anchor, the compass and the bomb.
+It is a medicine of much virtue and the only metal friendly to the human
+frame."[9]
+
+A metal that was so useful was needed in large quantities, yet the
+primitive forge could turn out only small quantities of iron. A day's
+labor at the bellows would produce a lump weighing only fifteen or
+twenty pounds. As a result of this slowness in manufacture there was
+always in primitive and ancient times a scarcity of iron. Indeed in some
+countries iron was a precious metal, almost as precious as silver or
+gold. In many countries, it is true, there were thousands of forges at
+work, but in no country was the supply of iron equal to the demand. The
+old forge could not supply the demand, yet centuries passed before any
+great improvement was made in the progress of iron making.
+
+[Illustration: FIG. 6.--A BLAST FURNACE OF THE MIDDLE AGES.]
+
+Near the close of the Middle Ages improvements upon the primitive forge
+began to be made. In the sixteenth century ironmakers in Germany began
+to smelt ore in closed furnaces and to build their furnaces higher and
+to make them larger (Fig. 6). Sometimes they built their furnaces to a
+height of twenty or thirty feet. About this time also a better and a
+stronger blast was invented. Water-power instead of hand-power began to
+be used for operating the bellows. In some cases wooden bellows--great
+wooden pistons working in tubs--were substituted for the old bellows of
+leather. By the end of the sixteenth century so many improvements had
+been made upon the primitive forge that it no longer resembled the forge
+of ancient times. So the new forge received a new name and was called a
+_blast furnace_.[10] You should observe, however, that the blast furnace
+was simply the old forge built with a large closed furnace and provided
+with a more powerful blast.
+
+
+The invention of the blast furnace marked the beginning of a new era in
+the history of iron making. In the first place there was produced in the
+blast furnace a kind of iron that was entirely different from that which
+was produced in the primitive forge. In the primitive forge there was
+made a lump of practically pure unmelted iron, known as wrought iron. In
+the blast furnace there was produced a somewhat impure grade of melted
+iron, known as _cast_ iron, or _pig_[11] iron. In the second place, the
+blast furnace produced iron in quantities vastly greater than it was
+ever produced by the old forge. In the blast furnace more iron could be
+made in a day than could be made by the forge in a month. In some of the
+early blast furnaces a thousand pounds of iron could be made at one
+melting and we read of one early furnace that produced 150 tons of iron
+in a year.
+
+[Illustration: FIG. 7.--MAKING CHARCOAL.]
+
+But even with the blast furnace it was still difficult to make enough
+iron to supply the ever-increasing demands of the industrial world. In
+the sixteenth and seventeenth centuries machinery was brought into use
+more than ever before and of course more iron was needed for the
+construction of the machines. There was ore enough for all the iron that
+was needed but it was difficult to get fuel enough to smelt the ore.
+Charcoal was still used as the fuel for smelting (Fig. 7), and in order
+to get wood for the charcoal great inroads were made upon the forests.
+In England in the early part of the eighteenth century Parliament had to
+put a check upon the manufacture of iron in certain counties in order to
+save the forests of those counties from utter destruction. It then
+became plain that if iron making were to be continued on a large scale a
+new kind of fuel would have to be used in the furnaces. So men set their
+wits to work to find a new kind of fuel. As far back as 1619 Dud Dudley
+in the county of Warwick, England, undertook to use ordinary soft coal
+in his furnaces but his experiment was not very successful or very
+profitable. More than a century after this an English ironmaker named
+Abraham Darby began (in 1735) to use _charred coal_ in his blast
+furnaces, and his experiments were successful. Here was the new fuel
+which was so badly needed. Charred coal is simply _coke_ and coke could
+be had in abundance. So the new fuel was soon used in all parts of
+England and by the end of the eighteenth century coke was driving
+charcoal out of blast furnaces (Fig. 8).
+
+About the time the use of coke for smelting became general, an
+Englishman named Neilson brought about another great change in the
+process of iron making. Before Neilson's time the blast driven into the
+furnace had always been one of cold air. Neilson learned that if the air
+before entering the furnace were heated to a temperature of 600 degrees
+it would melt twice the amount of ore and thus produce twice the amount
+of iron without any increase in the amount of fuel. So he invented (in
+1828) a _hot blast_ for the blast furnace (Fig. 9). With the use of coke
+and with the hot blast the production of iron increased enormously. But
+there was need for all the iron that could be made. Indeed it seems that
+the world can never get too much iron. About the time the hot blast was
+invented iron chains instead of ropes began to be used for holding
+anchors, iron plows began to be made in great numbers (p. 83), iron
+pipes instead of hollow wooden logs began to be used as water-mains in
+cities, and iron rails began to be used on railroads. To supply iron for
+all these purposes kept ironmakers busy enough, even though they burned
+coke in their furnaces and made use of the hot air blast.
+

+
+[Illustration: FIG. 9.--A MODERN BLAST FURNACE.]
+
+But ironmakers were soon to become busier than ever before. About the
+middle of the nineteenth century Sir Henry Bessemer invented a new
+process of making steel. Steel is only iron mixed with a small amount of
+carbon. Ironmakers have known how to make steel--and good steel,
+too--for thousands of years, but before the days of Bessemer the process
+had always been slow and tedious, and the cost of steel had always been
+very great. Bessemer undertook to make steel in large quantities and
+at low prices. In his experiments amid showers of molten metal he often
+risked his life, but his perseverance and courage were rewarded. By 1858
+he had invented a process by which tons of molten iron could be run into
+a furnace and in a few minutes be converted into a fine quality of
+steel. This invention of Bessemer was the last great step in the history
+of the forge.

+
+Now that steel could be made in great quantities and at a low cost it
+was put to uses never dreamed of in former times. Soon the railroad rail
+was made of steel (Fig. 10), bridges were made of steel, ships of war
+were plated with steel. Then ocean grayhounds and battleships were made
+of steel, still later steel freight cars and steel passenger coaches
+were introduced, while in our own time we see vast quantities of steel
+used in the building of houses. So while the invention of Bessemer
+marked the last step in the history of the forge it also marked the
+ending of the Age of Iron and the beginning of the wonderful age in
+which we live--the Age of Steel.

+for centuries, and of course where it was used it was still called a
+forge. Thus we are told that in Maryland in 1761, there were eight

+
+THE STEAM-ENGINE
+
+
+We have now traced the steps by which man mastered the art of kindling a
+fire quickly and easily and have followed the progress that has been
+made in the most common uses of fire. But the story of a most important
+use of fire remains to be told, the story of its use in doing man's
+_work_. How important this use is, how much of the world's work is done
+through the agency of fire, a little reflection will make plain. Fire
+makes steam and what does steam do? Its services are so many you could
+hardly name all of them. The great and many services of steam are made
+possible by the fire-engine, or _steam-engine_, and the story of this
+wonderful invention will now be told.
+
+That steam has the power to move things must have been learned almost as
+soon as fire was used to boil water. Heat water until it boils and the
+steam that is formed is bound to move something unless it is allowed to
+escape freely. It will burst the vessel if an outlet is not provided.
+That is why a spout has been placed on the tea-kettle. Where there is
+cooking, steam is abundant and the first experiments in steam were
+doubtless made in the kitchen (Fig. 1). It has been said that the idea
+of the steam-engine first occurred to Adam as he watched his wife's
+kettle boil.
+
+[Illustration: FIG. 1.--FIRST EXPERIMENTS WITH STEAM.]
+
+Whatever may have happened in ancient kitchens, we are certain that
+there were no steam-engines until many centuries after Adam. The
+beginnings of this invention are not shrouded in so much mystery as are
+those of the match and the lamp and the forge. In giving an account of
+the steam-engine we can mention names and give dates from the very
+beginning of the story. We know what the first steam-engine was like
+and we know who made it and when and where it was made. It was made
+120 B. C. by Hero, a philosopher of Alexandria in Egypt. It was like
+the one shown in Figure 2. The boy applies the fire to the steam-tight
+vessel _p_ and when steam is formed it passes up through the tube
+_o_ and enters the globe which turns easily on the pivots. The steam,
+when it has filled the globe, rushes out of the short tubes _w_ and _z_
+projecting from opposite sides of the globe and bent at the end in
+opposite directions. As it rushes out of the tubes the steam strikes
+against the air and the reaction causes the globe to revolve, just as in
+yards we sometimes see jets of water causing bent tubes to revolve. This
+was Hero's engine, the first steam-engine ever made.
+
+[Illustration: FIG. 2.--HERO'S ENGINE, 120 B. C.]
+
+Hero's engine was used only as a toy and it seems to represent all the
+ancients knew about the power of steam and all they did with it. It is
+not strange that they did not know more for there is no general rule by
+which discoveries are made. Sometimes even enlightened peoples have for
+centuries remained blind to the simplest principles of nature. The
+Greeks and Romans with all their culture and wisdom were ignorant of
+some of the plainest facts of science. It is a little strange, however,
+that after Hero's discovery was made known, men did not profit by it. It
+would seem that eager and persistent attempts would have been made at
+once to have steam do useful work, as well as furnish amusement. But
+such was not the case. Hero's countrymen paid but little attention to
+his invention and the steam-engine passed almost completely out of men's
+minds and did not again attract attention for nearly seventeen hundred
+years.
+
+About the end of the fifteenth century Europe began to awaken from a
+long slumber and by the end of the sixteenth century its eyes were wide
+open. Everywhere men were now trying to learn all they could. The study
+of steam was taken up in earnest about the middle of the sixteenth
+century and by the middle of the next century quite a little had been
+learned of its nature and power. In 1629 an Italian, Branca by name,
+described in a book a steam-engine which would furnish power for
+pounding drugs in a mortar. There was no more need for such a machine
+then than there is now and of course the inventor aroused no interest
+in his engine. You can easily understand how Branca's engine (Fig. 3)
+works. The steam causes the wheels and the cylinder to revolve. As the
+cylinder revolves, a cleat on it catches a cleat on the pestle and lifts
+the pestle a short distance and then lets it fall. Here the pestle
+instead of being raised by a human hand is raised by the force of steam.
+This engine would be more interesting if an engine had actually been
+made, but there is no reason to believe that Branca ever made the engine
+he described. We owe much to him, nevertheless, for suggesting how steam
+might be put to doing useful work.
+
+[Illustration: FIG. 3.--BRANCA'S ENGINE, 1629.]
+
+It was not very long before an Englishman put into practice what the
+Italian had only suggested. Edward Somerset, the Second Marquis of
+Worcester, in 1663 built a steam-engine that raised to the height of
+forty feet four large buckets of water in four minutes of time. This was
+the first useful work ever done by steam. Figure 4 shows the
+construction of Worcester's engine.
+
+[Illustration: FIG. 4.--WORCESTER'S ENGINE, 1663.]
+
+In this engine there was one improvement over former engines which was
+of the greatest importance: there was one vessel in which the steam was
+generated and another in which the steam did its work. The steam-engine
+now consisted of two great divisions, the boiler and the engine proper.
+
+Worcester spent a large part of his fortune in trying to improve the
+steam-engine, yet he received neither profit nor honor as a reward. He
+died poor and his name was soon forgotten. His service to the world was
+nevertheless very great. In his time the mines of England had been sunk
+very deep into the earth; and the deeper they were sunk the greater was
+the difficulty of lifting the water out of them and keeping them dry.
+The water was lifted up from the mines by means of buckets drawn by
+horses or oxen (Fig. 5). Sometimes it took several hundred horses to
+keep the water out of a single mine. It was Worcester's object to
+construct an engine that would do the work of the horses. The engine he
+built could not do this, yet it furnished the idea--and the idea is
+often the most important thing. It was not long before engines built
+upon Worcester's plan were doing useful work at the mines. At the
+opening of the eighteenth century the steam-engine had been put to work
+and was serving man in England and throughout the continent of Europe.
+
+[Illustration: FIG. 5.--AN ANCIENT METHOD OF DRAWING WATER.]
+
+[Illustration: FIG. 6.--PAPIN'S ENGINE, 1690.]
+
+The first engines were not safe. Often the steam pressed too heavily
+upon the sides of the vessel in which it was compressed and there were
+explosions. About 1680 Denis Papin, a Frenchman, invented the _safety
+valve_, that is a valve that opens of its own accord and lets out steam
+when there is more in the vessel than ought to be there. About ten years
+later Papin gave the world another most valuable idea. In Worcester's
+engine the steam in the steam chest pressed directly on the water that
+was to be forced up. Papin showed a better way. He invented the engine
+shown in Figure 6. In this engine a small quantity of water was placed
+in the bottom of the cylinder _A_. Fitting closely in the cylinder was a
+_piston_ _B_ such as Papin had seen used in ordinary pumps. We will
+suppose that the piston is near the bottom of the cylinder and that a
+fire is built underneath. The bottom being made of very thin metal the
+water is rapidly converted into steam and thus drives the piston up to
+the top as shown in the figure. Here a latch _E_ catches the piston-rod
+_H_ and holds the piston up until it is time for it to descend. Now the
+fire is removed and the steam, becoming cold, is condensed and a vacuum
+is formed below the piston. The latch _E_ now releases the rod _H_ and
+the piston is driven down by the air above it, pulling with it the rope
+_L_ which passes over the pulleys _TT_. As the rope descends it lifts a
+weight _W_ or does other useful work. As the inventor of the piston
+Papin ranks among the greatest of those whose names are connected with
+the development of the steam-engine.
+
+Our story has now brought us to the early part of the eighteenth
+century. Everywhere men were now trying to make the most of the ideas of
+Worcester and Papin. The mines were growing very deep. As the water in
+them was getting beyond control something extraordinary had to be done.
+Now it seems that whenever the world is in need of an extraordinary
+service someone is found to render that service. The man who built the
+engine that was needed was a humble blacksmith of Dartmouth, England,
+Thomas Newcomen. This master mechanic in 1705 constructed the best
+steam-engine the world had yet seen. We must study Newcomen's engine
+(Fig. 7) very carefully. The large beam _ii_ moved freely up and down on
+the pivot _v_. One end of the beam was connected with the heavy pump-rod
+_k_ by means of a rope or chain working in a groove and the other end
+was connected with the rod _r_ in the same way. When steam from the
+boiler _b_ passed through the valve _d_ into the cylinder (steam-chest)
+_a_ it raised the piston _s_ and with it the piston-rod _r_ thus
+slackening the rope and allowing the opposite end of the beam to be
+pulled down by the weight of the pump-rod _k_. As soon as the piston _s_
+reached the top of the cylinder the steam was shut off by means of the
+valve _d_ and the valve _f_ was turned and a jet of cold water from the
+tank _g_ was injected into the cylinder _a_ with the steam. The jet of
+cold water condensed the steam rapidly--steam is always condensed
+rapidly when anything cold comes in contact with it--and the water
+formed by the condensation escaped through the pipe _p_ into the tank
+_o_. As soon as the steam in _a_ is condensed, a vacuum was formed in
+the cylinder and the atmosphere above forced the piston down and at the
+same time pulled the pump-rod _k_ up and lifted water from the well or
+mine. When the piston reached the bottom of the cylinder the valve _d_
+was opened and the piston again ascended. Thus the beam is made to go up
+and down and the pumping goes on. Notice that steam pushes the piston
+one way and the atmosphere pushes it back.
+
+[Illustration: FIG. 7.--NEWCOMEN'S ENGINE, 1705.]
+
+In Newcomen's engine the valves (_f_ and _d_) at first were opened and
+shut (at each stroke of the piston) by an attendant, usually a boy. In
+1713 a boy named Humphrey Potter, in order to get some time for play, by
+means of strings and latches, caused the beam in its motion to open and
+shut the valves without human aid. We must not despise Humphrey because
+his purpose was to gain time for play. The purpose of almost all
+inventions is to save human labor so that men may have more time for
+amusement and rest. Humphrey Potter ought to be remembered not as a lazy
+boy but as a great inventor. His strings and latches improved the engine
+wonderfully (Fig. 8). Before his invention the piston made only six or
+eight strokes a minute; after the valves were made to open and shut by
+the motion of the beam, it made fifteen or sixteen strokes a minute and
+the engine did more than twice as much work.
+
+[Illustration: FIG. 8.--HUMPHREY POTTER'S LATCHES AND STRINGS.]
+
+Newcomen's engine as improved by Potter and others grew rapidly into
+favor. It was used most commonly to pump water out of the mines but it
+was put to other uses. In and about London it was used to supply water
+to large houses and in 1752 a flour mill near Bristol was driven by a
+steam-engine. In Holland Newcomen's engines were used to assist the
+wind-mills in draining lakes.
+
+[Illustration: FIG. 9.--JAMES WATT STRIVING TO IMPROVE NEWCOMEN'S
+ENGINE.]
+
+For nearly seventy-five years engines were everywhere built after the
+Newcomen pattern. Improvements in a small way were added now and then
+but no very important change was made until the latter part of the
+eighteenth century, when the steam-engine was made by James Watt
+practically what it is to-day. This great inventor spent years in making
+improvements upon Newcomen's engine (Fig. 9) and when his labors were
+finished he had done more for the steam-engine than any man who ever
+lived. We must try to learn _what_ he did. We can learn what Watt did by
+studying Figure 10. Here P is a piston working in a cylinder A _closed
+at both ends_. By the side of the cylinder is a _valve-chest_ C into
+which steam passes from the pipe T. Connecting C with the cylinder there
+are _two_ openings, one at the top of the cylinder and the other at the
+bottom. The valve-chest is provided with valves which are worked by
+means of the rod F, which moves up and down with the beam B, thanks to
+Humphrey Potter for the hint. The valves are so arranged that when steam
+enters the opening at the top of the cylinder it is shut off from the
+opening at the bottom, and when it enters the opening at the bottom it
+is shut off from the opening at the top. When the opening at the bottom
+is closed the steam will rush in at the upper opening and push the
+piston downward; when the piston has nearly reached the bottom of the
+cylinder the upper opening will be closed and steam will rush in at the
+bottom of the steam chest and push the piston upwards. Here was _one_
+of the things done by Watt for the engine: he contrived to make the
+steam push the piston down as well as up. You have observed that in
+Newcomen's engine steam was used only to push the piston _up_, the
+atmosphere being relied upon to push it down. Thus we may say that
+Watt's engine was the first _real steam-engine_, for it was the first
+that was worked entirely by steam. All engines before it had been worked
+partly by steam and partly by air.
+
+[Illustration: FIG. 10.--WATT'S ENGINE.]
+
+Watt's greatest improvement upon the steam-engine is yet to be
+mentioned. In Newcomen's engine when the cold water was injected into
+the cylinder it cooled the piston and when steam was let into the
+cylinder again a part of it, striking the cold piston, was condensed
+before it had time to do any work and the power of this part of the
+steam was lost. Watt did not allow the piston to get cold, for he did
+not inject any cold water into the cylinder. In his engine as soon as
+the steam did its work it was carried off through the pipe _M_ to the
+vessel _N_ and there condensed by means of a jet of water which was
+injected into _N_ (called the _condenser_) by means of a pump _E_ worked
+by the motion of the beam, thanks again to Humphrey Potter for the idea.
+This condensation of the steam outside of the cylinder and at a distance
+from it prevented the piston (and cylinder) from getting cold. In other
+words, in the Watt engine when steam entered the cylinder it went
+straight to work pushing the piston. No steam was lost and no power was
+lost and the cost of running the engine was greatly reduced.
+
+It cannot be said that Watt invented the steam-engine--no one can claim
+that honor--yet he did so much to make it better that he well deserves
+the epitaph which is inscribed on his monument in Westminster Abbey.
+This inscription is as follows:
+
+ NOT TO PERPETUATE A NAME
+ WHICH MUST ENDURE WHILE THE PEACEFUL ARTS
+ FLOURISH
+ BUT TO SHEW
+ THAT MANKIND HAVE LEARNT TO HONOR THOSE
+ WHO BEST DESERVE THEIR GRATITUDE

+ SCIENCE
+ AND THE REAL BENEFACTORS OF THE WORLD
+ BORN AT GREENOCH MDCCXXXVI
+ DIED AT HEATHFIELD IN STAFFORDSHIRE
+ MDCCCXIX
+
+But the story of the steam-engine does not end with Watt. It will be
+remembered that in the engines of Nero and of Branca the steam did its
+work by reaction or by impulse. Now soon after the time of Watt,
+inventors turned their thoughts to the old engines of Nero and Branca
+and began to experiment with engines that would do their work by a
+direct impact of steam. After nearly a century of experimenting and
+after many failures there was at last developed an engine known as the
+_steam-turbine_. In this engine the steam does its work by impinging or
+pushing directly upon blades (Fig. 11) which are connected with the
+shaft which is to be turned, and it does this in much the same manner
+that we saw the steam do its work in Branca's engine. One of the
+greatest names connected with the steam turbine is that of Charles
+Algernon Parsons of England. In 1884 this great inventor patented a
+steam-turbine which proved to be a commercial success and since that
+date the steam-turbine has been constantly growing in favor. So great
+has been its success on land and on sea that there are those who believe
+that the engine invented by Watt will in time be cast aside and that its
+place will be taken by an engine which is the most ancient as well as
+the most modern of steam motors.
+
+[Illustration: FIG. 11.--SHAFT OF A LARGE MARINE TURBINE.
+
+Within the cylinder are thousands of blades upon which the steam acts
+directly in the turning of the shaft. In the largest turbines there are
+as many as 50,000 blades.]

+
+
+
+THE PLOW
+
+
+You have now learned the history of those inventions which enabled man
+to gain a mastery over fire and to use it for his comfort and
+convenience. We shall next learn the history of an invention which gave
+man the mastery of the soil and enabled him to take from the earth
+priceless treasures of fruit and grain. This invention was the plow.
+
+In his earliest state man had no use for the plow because he did not
+look to the soil as a place from which he was to get his food. The first
+men were hunters and they relied upon the chase for their food. They
+roamed from place to place in pursuit of their prey--the birds and
+beasts of the forest and the fishes of the stream. They did not remain
+long enough in one spot to sow seed and to reap the harvest. Still in
+their wanderings they found wheat and barley growing wild and they ate
+of the seeds of these plants and learned that the little grains were
+good for food. They learned, too, that if the seeds were planted in a
+soil that was well stirred the plants would grow better than they would
+if the seeds were planted in hard ground. So by the time men had grown
+tired of wandering about and were ready to settle down and live in one
+spot they had learned two important facts: they knew they could add to
+their food supply by tilling the soil, and they knew that they could
+grow better crops if they would stir the soil before planting the seed.
+
+[Illustration: FIG. 1.--THE KATTA OR DIGGING STICK.]
+
+For the stirring of the soil the primitive farmer doubtless first used a
+sharpened stick such as wandering tribes carry for the purpose of
+digging up eatable roots, knocking fruits down from trees, and breaking
+the heads of enemies. Such a stick known as the _Katta_ (Fig. 1) is
+carried by certain tribes in Australia, and we are told by travelers
+that the Kurubars of Southern India use a sharp stick when digging up
+the ground. The digging stick is used by savages in many parts of the
+world and we may regard it as the oldest of implements used for tilling
+the soil.
+
+[Illustration: FIG. 2.--THE FIRST PLOW.]
+
+The first plow was a forked stick or a limb of a tree with a projecting
+point (Fig. 2). With this implement the ground was broken not by digging
+but by dragging the fork or projecting point of the stick through the
+ground and forming a continuous furrow. In this forked stick we see two
+of the principal parts of the modern plow. The fork of the stick is the
+_share_, or cutting part of the plow, while the main part of the stick
+is the _beam_.
+
+[Illustration: FIG. 3.--THE SYRIAN PLOW KNOWN AS JOB'S PLOW.]
+
+An improvement upon the simple forked stick is seen in Figure 3, which
+is copied from an ancient monument in Syria (in Asia Minor). The old
+Syrian plow consists almost wholly of the natural crooks of a branch of
+a tree, the only artificial piece being the brace e which connects the
+share and the beam and holds them firm. In this crooked stick we have
+three of the main parts of the modern plow, the beam (a), the share
+(c-b) and the handle (d). The plow in this form requires the services of
+two persons--one to draw the plow and one to guide it and keep it in the
+ground. It is said that it was with a plow of this kind that the
+servants of Job were plowing when they were driven from their fields by
+the Sabeans.
+
+The first plows were drawn by the strength of the human body (Fig. 4).
+Upon a very old monument of ancient Egypt, the country which seems to
+have been the first home of the plow, we have a plowing scene which
+shows a number of men dragging a plow by means of a rope. But primitive
+man was not at all fond of labor and in the course of time he tamed wild
+bulls and horses and made them draw the plows. So upon another Egyptian
+monument of a later date we have a picture of a plowing scene in which
+animals are drawing the plow (Fig. 5). In this Egyptian plow we see
+improvements upon the crooked stick of the Syrians. The Egyptian plow,
+you observe, has a broader share. It will, therefore, make a wider
+furrow and will plow more ground. Moreover, it has two handles instead
+of one. Taking it altogether, the Egyptian plow was a fairly good
+implement.
+
+[Illustration: FIG. 4.--PLOW DRAWN BY HUMAN LABOR.]
+
+[Illustration: FIG. 5.--THE EGYPTIAN PLOW.]
+
+Many centuries passed before any real improvement was made upon the old
+Egyptian plow. If there were any improvement anywhere it was among the
+Romans. We read in Pliny--a Roman writer of the first century--of a
+plow that had wheels to regulate the depth of the plow and also a
+_coulter_, that is, a knife fixed in front of the share to make the
+first cut of the sod (Fig. 6). But such a plow was not in general use in
+Pliny's time. A thousand years later, however, the plow with wheels and
+coulter was doubtless in common use. In a picture taken from an old
+Saxon print we see (Fig. 7) a plow which was used in the time of William
+the Conqueror (1066). Here the plow has a coulter inserted in the beam
+and there are two wheels to regulate the depth to which the plow may go.
+This Saxon plow is drawn by four fine oxen and it is plainly a great
+improvement upon the old Egyptian plow.
+
+[Illustration: FIG. 6.--PLINY'S PLOW, 70 A. D.]
+
+[Illustration: FIG. 7.--AN OLD SAXON PLOW, 1000 A. D.]
+
+[Illustration: FIG. 8.--A DOUBLE PLOW OF THE SEVENTEENTH CENTURY.
+
+(This plow was proposed but was never made.)]
+
+But improvements in the plow during the dark ages came very slowly. At
+the time of the discovery of America the plow was still the clumsy
+wooden thing it was five hundred years before. In the sixteenth and
+seventeenth centuries, however, when improvements were being made in so
+many things, it was natural that men should begin to think of trying to
+improve the plow. In an old book published in 1652 we read of a double
+plow--one which would plow two furrows at one time. A picture (Fig. 8)
+of the double plow is given in the book but there is no proof that such
+a plow was ever made or ever used. The world did not as yet need a
+double plow, although the time was to come when it would need one.
+
+In the early part of the eighteenth century we begin to see real
+improvements in plow making. About this time Dutch plowmakers began to
+put _mold-boards_ on their plows. The purpose of the mold-board is to
+lift up and turn over the slice of sod cut by the share. Without the
+mold-board the plow simply runs through the ground and stirs it up.
+With the mold-board of the Dutch plow (Fig. 9) the sod was turned
+completely over and the weeds and grass were covered up. This was the
+kind of plow that was needed, for if the weeds and grass are not covered
+up the best effects of plowing are lost. So the mold-board was a great
+improvement and its invention marks a great event in the history of the
+plow.
+
+[Illustration: FIG. 9.--THE DUTCH PLOW SHOWING THE MOLD-BOARD.]
+
+The Dutch plow was taken as a model for English plows and, in fact, for
+the plows of all nations. The mold-board grew rapidly into favor and by
+the end of the eighteenth century it was found on plows in all civilized
+nations. But the plow was still made mostly of wood (Fig. 10) and it was
+still an awkward and a poorly constructed affair. The method of making
+plows about the year 1800 has been described as follows: "A mold-board
+was hewed from a tree with the grain of the timber running as nearly
+along its shape as it could well be obtained. On to this mold-board, to
+prevent its wearing out too rapidly, were nailed the blade of an old
+hoe, thin strips of iron, or worn out horseshoes (Fig. 10). The land
+side was of wood, its base and sides shod with thin plates of iron. The
+share was of iron with a hardened steel point. The coulter was tolerably
+well made of iron. The beam was usually a straight stick. The handles,
+like the mold-board, were split from the crooked trunk of a tree or as
+often cut from its branches. The beam was set at any pitch that fancy
+might dictate, with the handles fastened on almost at right angles with
+it, thus leaving the plowman little control over his implement, which
+did its work in a very slow and most imperfect manner."
+
+[Illustration: FIG. 10.--A COLONIAL PLOW.]
+
+But about the end of the eighteenth century the world was beginning to
+need a plow that would do its work rapidly and well. Population was
+everywhere increasing and it was necessary to till more ground than had
+ever been tilled in former times. Especially was a good plow needed in
+the United States where there were vast areas of new ground to be
+broken. And it was in the United States that the first great
+improvements in the plow were made. Foremost among those who helped to
+make the plow a better implement was the statesman, Thomas Jefferson.
+This great man while traveling in France in 1788 was struck by the
+clumsiness of the plows used in that country. In his diary he wrote:
+"The awkward figure of their mold-board leads one to consider what
+should be its form." So Jefferson turned his attention to mold-boards.
+He saw that the mold-board ought to be so shaped that it would move
+through the ground and turn the sod with the least possible resistance
+and he planned for a mold-board of this kind. By 1793 he had determined
+what the proper form of a mold-board should be and had in actual use on
+his estate in Virginia several plows which had mold-boards of least
+resistance. Mr. Jefferson's patterns of the mold-board have, of course,
+been improved upon, but he has the honor of having invented the first
+mold-board that was constructed according to scientific and mathematical
+principles.[12]
+
+[Illustration: FIG. 11.--DANIEL WEBSTER'S PLOW.]
+
+[Illustration: FIG. 12.--JETHRO WOOD'S PLOW, 1819.]
+
+About the time Jefferson was working upon the mold-board, Charles
+Newbold, a farmer of Burlington, New Jersey, was also doing great things
+for the improvement of the plow. We have seen that the plow of this time
+was a patch work of wood and iron. Newbold thought the plow ought to be
+made wholly of iron and about 1796 he made one of cast iron, the point,
+share, and mold-board all being cast in one piece. But the New Jersey
+farmers did not take kindly to the iron plow. They said that iron
+poisoned the crops and caused weeds to grow faster than ever. So Newbold
+could not sell his plows and he was compelled to give up the business in
+despair.
+
+But soon the iron plow was to have its day. In 1819 Jethro Wood of
+Scipio, New York, took out a patent for a plow which was made of cast
+iron and which combined the best features of the plow as planned by
+Jefferson and by Newbold. In Wood's plow (Fig. 12) the several
+parts--the point, share and mold-board--were so fastened together that
+when one piece wore out it could easily be replaced by a new piece. In
+Newbold's plow when one part wore out the whole plow was rendered
+useless. Wood's plow became very popular and by 1825 it was rapidly
+driving out the half-wooden, half-iron plows of the olden time. Great
+improvements of course have been made upon the plow since 1819, but in
+the main features the best plows of to-day closely resemble the
+implement invented by Jethro Wood. Since our greatness as a nation is
+due largely to the plow all honor should be given to the memory of this
+inventor. "No citizen of the United States," said William H. Seward,
+"has conferred greater benefits on his country than Jethro Wood."
+
+[Illustration: FIG. 13.--THE GANG PLOW DRAWN BY HORSES.]
+
+[Illustration: FIG. 14.--PLOWING BY STEAM.
+
+The plow is drawn across the field by means of cables. Sometimes a
+traction engine moves along with the plow.]
+
+But the plow of Jethro Wood, as excellent as it was, did not fully meet
+the needs of the western farmer. The sod of the vast prairies could not
+be broken fast enough with a plow of a single share. So about the middle
+of the nineteenth century the _gang plow_, a hint for which had been
+given long before (p. 78) was invented, and as this new plow moved along
+three or four or five furrows were turned at once. At first the gang
+plow was drawn by horses (Fig. 13) but later it was drawn by steam (Fig.
+14).
+
+The great gang plow drawn by steam marked the last step in the
+development of the plow. The forked stick drawn by human hands and
+making its feeble scratch on the ground had grown until it had become a
+mighty machine drawn across the field by an unseen force and leaving in
+its wake a broad belt of deeply-plowed and well-broken soil.
+
+
+FOOTNOTE:
+
+[12] Daniel Webster was another great statesman who turned his attention
+to the making of plows. He planned a plow (Fig. 11) and had it made in
+his workshop on his farm at Marshfield. When the plow was ready for use,
+Webster himself was the first man to take hold of the handles and try
+it. The plow worked well and the great man is said to have been as much
+delighted with his achievement as he was with any of his triumphs in
+public life at Washington.

+
+THE REAPER
+
+
+After man had invented his rude plow and had learned how to till the
+soil and raise the grain, it became necessary for him to learn how to
+harvest his crop, how to gather the growing grain from the fields. The
+invention of the plow, therefore, must have soon been followed by the
+invention of the _reaper_.
+
+[Illustration: FIG. 1.--PRIMITIVE SICKLES.]
+
+The first grain was doubtless cut with the rude straight knives used by
+primitive man. In time it was found that if the knife were bent it would
+cut the grain better. So the first form of the reaper was a curved or
+bent knife known as the sickle or reaping hook (Fig. 1). The knife was
+fastened at one end to a stick which served as a handle. When using the
+sickle the harvester held the grain in one hand and cut it with the
+other. (Fig. 2).
+
+[Illustration: FIG. 2.--REAPING WITH THE SICKLE.]
+
+_When_ the sickle first began to be used is of course unknown. Among
+the remains of the "stone age" (p. 39) are implements of flint which
+resemble the sickle, while among the remains of the so-called "bronze
+age" many primitive sickles made of bronze have been found. Nor do we
+know _where_ the sickle was first used, although Egypt seems to have
+been the first home of the sickle just as it was the first home of the
+plow. Upon the wall of a building of ancient Thebes is a picture of an
+Egyptian harvest scene. Two men with sickles are cutting the wheat. A
+man following the reapers seems to be gleaning, that is, picking up the
+wheat that the reapers have cut. Other harvesters are carrying the grain
+to the threshing place where it is tramped out by the slow feet of oxen.
+A primitive sickle such as was used by the Egyptians was used by all
+civilized nations in ancient times, by the Hebrews, by the Greeks, and
+by the Romans.
+
+The first improvement upon the primitive sickle was made by the Romans.
+About the year 100 A. D. the Roman farmers, who were at the time the
+best farmers in the world, began to use a kind of scythe for cutting
+grass. The Roman scythe was simply an improved form of the sickle; it
+was a broad, heavy blade fastened on a long straight handle, resembling
+the pruning hook of to-day (Fig. 3). The scythe was swung with both
+hands and it was used chiefly for cutting grass.
+
+For more than a thousand years after the appearance of the Roman scythe
+agriculture in Europe was everywhere neglected and little or no
+improvement was made in farming implements. About the end of the Middle
+Ages, however, improvements in the form of the scythe began to appear.
+In Flanders farmers began to use an implement known as the Hainault
+scythe (Fig. 4). This scythe had a fine broad blade and a curved handle.
+When reaping with this scythe the reaper with his left hand brought the
+stalks of grain together with a hook and with his right hand he swung
+the scythe and cut the grain. This scythe was an improvement upon the
+sickle but it was still a very awkward implement.
+
+[Illustration: FIG. 3.--AN EARLY SCYTHE.]
+
+[Illustration: FIG. 4.--THE HAINAULT OR FLEMISH SCYTHE, WITH HOOK.]
+
+The Hainault or Flemish scythe was followed by the _cradle scythe_. On
+this scythe (Fig. 5) there were wooden fingers running parallel to the
+blade. These fingers, called the cradle, caught the grain as it was cut
+and helped to leave it in a bunch. In the early cradle-scythe the
+fingers were few in number and they ran along the blade for only a part
+of its length, but in America during the colonial period the cradle was
+improved by lengthening the fingers and increasing their number. At the
+time of the Revolution the improved American cradle was coming into use
+and by the end of the eighteenth century it was driving out the sickle.
+
+[Illustration: FIG. 5.--EARLY FORM OF THE CRADLE SCYTHE.]
+
+[Illustration: FIG. 6.--THE IMPROVED CRADLE SCYTHE.]
+
+But even the excellent American cradle-scythe could not meet the needs
+of the American farmer. The cast iron plow which was brought into use in
+the early part of the nineteenth century (p. 82) made it possible to
+raise fields of wheat vastly larger than had ever been raised before.
+But it was of no use to raise great fields of grain unless the crop
+could be properly harvested. Wheat must be cut just when it is ripe and
+the harvest season lasts only a few days. If the broad American fields
+were to be plowed and planted there would have to be a reaping machine
+that would cut the grain faster than human hands could cut it with the
+scythe (Fig. 6).
+
+[Illustration: FIG. 7.--THE FIRST REAPING MACHINE, 70 A. D.]
+
+So about the year 1800 inventors in Europe and in America took up the
+task of inventing a new kind of reaper. The first attempts were made in
+England where population was increasing very fast and where large
+quantities of grain were needed to feed the people. The first hints for
+a reaper were from a machine which was used in Gaul nearly 2,000 years
+ago. Pliny, who described for us a wonderful plow used in his time (p.
+77), also describes this ancient reaper of the Gauls. It consisted of a
+large hollow frame mounted on two wheels (Fig. 7). At the front of the
+frame there was a set of teeth which caught the heads of grain and tore
+them off. The heads were raked into the box by an attendant. The machine
+was pushed along by an ox. This kind of machine was doubtless used in
+Europe for a while but it was not a success. It passed out of use and
+for many centuries it was entirely forgotten. Still, the first English
+reaping machines were made after the plan of this interesting old reaper
+of ancient Gaul.
+
+[Illustration: FIG. 8.--OGLE'S REAPER, 1822.]
+
+The most remarkable of the early reapers was one invented by Henry Ogle,
+a schoolmaster of Remington, England. In 1822 Ogle constructed a model
+for a reaper which was quite different from any that had appeared before
+and which bore a close resemblance to the improved reapers of a later
+date. In Ogle's reaper (Fig. 8) the horse walked ahead beside the
+standing grain, just as it does now, and the cutting apparatus was at
+the right, just as it is now. The cutter consisted of a frame at the
+front of which was a bar of iron armed with a row of teeth projecting
+forward. Directly under the teeth lay a long straight edged knife which
+was moved to and fro by means of a crank and which cut the grain as it
+came between the teeth. A reel pushed the grain toward the knife and
+there was a platform upon which the grain when cut might fall. Ogle's
+machine did not meet with much success yet it holds a very high place
+in the history of reaping machines, for it had nearly all the parts of a
+modern reaper.
+
+[Illustration: FIG. 9.--THE FIRST MCCORMICK REAPER.]
+
+English inventors did much to prepare the way for a good reaping machine
+but the first really successful reaper, the first reaper that actually
+reaped, was made in the United States. In the summer of 1831, Cyrus
+McCormick, a young blacksmith living in the Shenandoah Valley in
+Virginia, made a trial of a reaper which he and his father had
+invented--how much they had learned from Ogle we do not know--and the
+trial was successful (Fig. 9). With two horses he cut six acres of oats
+in an afternoon. "Such a thing," says Mr. Casson in his life of
+McCormick, "at the time was incredible. It was equal to the work of six
+laborers with scythes or twenty-four peasants with sickles. It was as
+marvelous as though a man had walked down the street carrying a dray
+horse on his back."
+
+Although McCormick had his reaper in successful operation by 1831 he did
+not take out a patent for the machine until 1834. One year before this
+(in 1833) Obed Hussey, a sailor living in Baltimore, took out a patent
+for a reaper that was successful and that was in many respects as famous
+a machine as McCormick's. So while McCormick was the first in the field
+with his invention, Hussey was the first to secure a patent. The
+machines of McCormick and Hussey were very much alike: both had the
+platform, the iron bar armed with guards and the long knife moving to
+and fro. The most remarkable feature of Hussey's machine was the knife
+which consisted of thin triangular plates of steel sharpened on two
+edges and riveted side by side upon a flat bar (Fig. 10). The saw-like
+teeth of Hussey's knife caught the wheat between the guards and cut it
+better than any knife that had as yet appeared. Both the McCormick
+reapers and the Hussey reapers were practical and successful and each of
+these inventors performed a noble part in giving the world the reaper it
+needed.
+
+[Illustration: FIG. 10.--THE KNIFE BLADE OF HUSSEY'S REAPER.]
+
+The McCormick and the Hussey reapers gave new life to farming in the
+United States. Especially was the reaper a blessing to the Western
+farmers. In 1844 McCormick took a trip through the West, passing through
+Ohio, Michigan, Illinois, and Iowa. As he passed through Illinois he saw
+how badly the reaper was needed. He saw great fields of ripe wheat
+thrown open to be devoured by hogs and cattle because there were not
+enough laborers to harvest the crops. The farmers had worked day and
+night and their wives and children had worked but they could not harvest
+the grain; they had raised more than the scythe and sickle could cut.
+McCormick saw that the West was the natural home for the reaper and in
+1847 he moved to Chicago, built a factory, and began to make reapers. In
+less than a year he had orders for 500 machines and before ten years had
+passed he had sold nearly 25,000 reapers. It was these reapers that
+caused the frontier line to move westward at the rate of thirty miles a
+year.
+
+[Illustration: FIG. 11.--REAPER PROVIDED WITH SEAT FOR THE RAKER.]
+
+Improvements upon the machines of Hussey and McCormick came thick and
+fast. One of the first improvements was to remove the grain from the
+platform in a better way. With the first machines a man followed the
+reaper (Fig. 9) and removed the grain with a rake. Then a seat was
+provided and the man sat (Fig. 11) on the reaper and raked off the
+grain. Finally the _self-raking_ reaper was invented. In this machine,
+as it appeared in its completed form about 1865, the reel and rake were
+combined. The reel consisted of a number of revolving arms each of
+which carried a rake (Fig. 12). As the arms revolved they not only moved
+the standing grain toward the knife, but they also swept the platform
+and raked off the wheat in neat bunches ready to be bound into sheaves.
+So the self-raking reaper saved the labor of the man who raked the wheat
+from the platform.
+
+[Illustration: FIG. 12.--SELF-RAKING REAPER.]
+
+Because it saved the labor of one man the self-raking reaper was for a
+time the king of reaping machines. But it did not remain king long, for
+soon there came into the harvest fields a reaper that saved the labor of
+several men. This was the _self-binder_. With the older machines, as the
+grain was raked off the platform it was gathered and bound into sheaves
+by men who followed the reaper, one reaper requiring the services of
+three or four or five human binders. With the self-binder (Fig. 13) the
+grain was gathered into sheaves and neatly tied without the aid of human
+hands. At first, wire was used in binding the sheaves but by 1880 most
+self-binders were using twine. So the self-binder saved the labor not
+only of the man who raked the grain from the platform but it saved the
+labor of all the binders as well.
+
+[Illustration: FIG. 13.--A SELF-BINDING REAPER.]
+
+[Illustration: FIG. 14.--A COMBINED HARVESTER AND THRESHER.]
+
+The last step in the development of the reaper was taken when the
+_complete harvester_ was invented. This machine cuts the standing grain,
+threshes it, winnows[13] it, and places it in sacks (Fig. 14). As this
+giant reaper travels over the field one sees on one side the cutting bar
+15 to 25 feet in length slicing its way through the wheat, while on the
+other side of the machine streams of grain run into sacks which, as fast
+as they are filled, are hauled to the barn or to the nearest railway
+station. The complete harvester is either drawn by horses--30 or 40 in
+number--or by a powerful engine. It cuts and threshes 100 acres of wheat
+in a day and the cost is less than 50 cents an acre. It does as much
+work in a day as could have been done by a hundred men before the days
+of McCormick. Of all the wonderful machines used by farmers the most
+wonderful is the complete harvester, the latest and the greatest of
+reapers.
+
+

+[13] To winnow grain is to separate it from the chaff by a fanning
+process.

+
+
+THE MILL
+
+
+[Illustration: FIG. 1.--THE FIRST MILL.]
+
+The first mill was a hole made in a stationary rock (Fig. 1). The grain
+was placed in the hole and crushed with a stone held in the hand. On
+Centre street in Trenton, New Jersey, not many years ago one of these
+primitive mills could still be seen and there are evidences that such
+mills once existed in all parts of the world. In those places where the
+earth did not supply the stationary rock, stones were brought from afar
+and hollowed out into cup-like form and in these the grinding was done.
+
+[Illustration: FIG. 2.--THE KNOCKING-STANE.]
+
+The mill which consisted of a hole in a rock and a stone in the hands
+was followed by the "knocking-stane" and mallet (Fig. 2). The
+"knocking-stane" was a mortar, or cup-shaped vessel made of stone; the
+mallet was usually made of wood. The grain was placed in the mortar and
+struck repeatedly with the mallet, the beating being kept up until a
+coarse flour was produced. This is an exceedingly rude method of
+crushing grain, yet this is the way the people in some parts of Scotland
+grind their barley at the present time.
+
+[Illustration: FIG. 3.--MORTAR AND PESTLE MILL.]
+
+At a very early date the "knocking-stane" was laid aside for the mortar
+and pestle (Fig. 3) almost everywhere. In this mill the grain instead of
+being struck with a hammer was pounded with a pestle. The bottom of the
+pestle was frequently covered with iron in which grooves were cut. As
+the man pounded he found that when he gave the pestle a twirling or
+rotary motion as it fell it ground the grain much faster. We may be sure
+that after this was learned the twirling motion was always given.
+
+The mortar and pestle were followed by the slab-mill (Fig. 4). Here the
+grain was ground by being rubbed between two stones. Dr. Livingstone,
+the great African explorer, gives the following description of a
+slab-mill which he saw in operation in South Africa. "The operator
+kneeling grasps the upper millstone with both hands and works it
+backwards and forwards in the hollow of the lower millstone, in the same
+way that a baker works his dough. The weight of the person is brought to
+bear on the movable stone and while it is pressed and pushed forward and
+backward one hand supplies every now and then a little grain to be
+bruised and ground."
+
+[Illustration: FIG. 4.--THE SLAB-MILL.]
+
+[Illustration: FIG. 5.--THE UPPER AND NETHER MILLSTONE.]
+
+As we have seen, the primitive miller gradually learned that the pestle
+did better work when it fell with a twirling motion. This little bit of
+experience led to important results in the development of the mill. If
+the grinding were done better with a twirling motion, why not have as
+much of the twirling motion as possible? Why not make the upper stone go
+round and round? This was what was done. The upper stone was caused to
+turn round and round. The wheel-mill, the mill of the upper and nether
+millstone (Fig. 5), was invented. When and where it was invented we
+cannot tell for it was in use among all civilized peoples before history
+began to be written. There were many kinds of wheel-mills among the
+nations of antiquity and in principle they were all alike in
+construction. How they worked may be learned by studying Figure 5 which
+represents a mill used in ancient India. The upper stone is placed upon
+the pivot projecting from the center of the lower (nether) stone, and
+caused to revolve by means of the handle. The grain when placed in the
+hollow at the center of the upper stone (Fig. 5) works its way down
+between the stones and comes out at the circumference ground, bran and
+flour together. The mill was fed with grain by the operator. The first
+hopper was a human hand.

+

+
+[Illustration: FIG. 9.--POMPEIAN FLOUR MILL, 79 A. D.]
+
+We have here several pictures of ancient mills. Figure 6 is an ancient
+Jewish mill. As we look at it we may recall the words, "Two women shall
+be grinding at a mill, the one shall be taken, and the other left."[14]
+Figure 7 is an old Roman mill bearing a strong resemblance to the coffee
+mill that is used in our kitchens. Figure 8 is a Scottish quern, a mill
+that may still be found in use, it is said, in some parts of Scotland.
+Figure 9 is an old flour mill dug from the ruins of the city of Pompeii
+which was destroyed by an eruption in the year 79 A. D. Figure 10 shows
+the construction of this interesting mill. The upper (outer) stone is
+shaped like an hour-glass, the upper half of which serves as a hopper;
+the lower half turns upon the cone-shaped lower stone and does the
+grinding. The mill was operated by the projecting handles, the operators
+walking round and round the mill. Sometimes it was turned by human
+power, sometimes by horses or oxen.
+
+[Illustration: FIG. 10.--SHOWING THE INTERIOR OF POMPEIAN MILL.]
+
+[Illustration: FIG. 11.--THE FIRST WATER-MILL, 50 B. C.]
+
+[Illustration: FIG. 12.--SHOWING THE INTERIOR OF THE FIRST WATER-MILL.]
+
+The Pompeian mill shows that as early as the first century the Romans
+ground their grain by animal power. Indeed about this time a still
+greater change was made in the method of grinding grain. When Julius
+Cæsar flourished (50 B. C.) men began to harness the power of running
+water and make it turn their mills (Fig. 11). From Figure 12 we may
+easily learn how this was done. The running water turns the wheel and in
+doing so turns the upper millstone. A hopper is suspended from the roof
+by ropes. Through this the grain passes into the mill. Here was a
+great saving in human labor and a great advancement in mill making. A
+Roman writer of Cæsar's time appreciating how great a blessing was the
+invention of the water-mill exclaimed:
+
+ Ye maids who toiled so faithful at the mill
+ Now cease from work and from these toils be still;
+ Sleep now till dawn and let the birds with glee
+ Sing to the ruddy morn, on bush and tree;
+ For what your hands performed so long, so true,
+ Ceres[15] has charged the water-nymphs to do;
+ They come, the limpid sisters, to her call,
+ And on the wheel with dashing fury fall;
+ Impel the axle with a whirling sound
+ And make the massive millstone reel around
+ And bring the floury heap luxuriant to the ground.
+
+Nothing can be simpler than the water-mill described above; it was the
+old mill of the upper and nether millstones, the old hand mill turned by
+water. That was all. Yet, as simple as it was, many centuries passed
+after its invention before a new principle in flour making was
+discovered. There were inventions for lowering and raising the stone so
+as to grind finer or coarser as might be desired, and there were
+improvements in the kind of water wheels employed, and better methods of
+sifting the flour from the bran were discovered from time to time, but
+the water-mill invented in the time of Julius Cæsar remained practically
+unchanged until the early part of the nineteenth century, when the last
+step in the development of the mill was taken.[16]
+
+[Illustration: FIG. 13.--AN EARLY FLOUR ROLLER-MILL.]
+
+About 1810 millers in Austria, more particularly those in Vienna, began
+to grind their grain by passing it between two horizontal rollers (Fig.
+13). The rollers were spirally grooved and turned toward each other.
+There was a wide difference between this process and the one to which
+the world was accustomed, yet the new method was found to be better than
+the old one. Austrian flour and Austrian bread became famous. The
+delicious Vienna bread on our tables of course has never seen Vienna. It
+is called "Vienna bread" because it is made out of a kind of flour which
+was first ground in the Austrian capital. The Austrian way of grinding
+grew rapidly into favor among millers everywhere. In the United States
+where there was so much wheat to be ground the roller process was taken
+up eagerly and improved upon as only Americans know how to improve upon
+an idea. In the flour mills of the West the grain was soon passing
+through a series of rollers. By the first pair of rollers the grain was
+simply cracked into pieces somewhat coarse. Then after being bolted
+(sifted) it was passed between a second pair of rollers and reduced to a
+greater fineness. Then it was bolted again and passed between a third
+pair of rollers. The rolling and sifting continued until a practically
+pure flour was obtained. A pure flour is the modern miller's ideal. He
+wants a branless flour and a flourless bran. The old stone mill could
+not grind this kind of flour. Before the roller mill appeared there was
+always bran in the flour and flour in the bran.
+
+[Illustration: FIG. 14.--A MODERN FLOUR ROLLER-MILL.]
+
+The invention of the flour roller-mill (Fig. 14) is the last step in the
+development of the mill. The roller process has almost entirely driven
+out all other processes. Now and then we see by the roadside an old
+fashioned mill with the upper and nether stone, but we seldom see one
+that is prosperous and thriving. Millers, like everybody else in these
+days, do business on a large scale and to make flour on a large scale
+they must use the roller-mill. Thus the hole in the rock in which a
+handful of grain was laboriously crushed has, through long ages of
+growth, become the great factory in which thousands of barrels of flour
+are made in a day.

+
+THE LOOM
+
+
+Have you ever seen a loom? It would not be a wonder if you have not. In
+these days the average person seldom sees one. Everyone knows in a vague
+sort of way that clothes and carpets are made of wool or silk or cotton,
+as the case may be, and that they are woven upon an instrument called a
+loom. This is about as much as we usually know about the clothes we wear
+or the carpets we walk upon. We buy these things from the store and that
+is all there is to it. In the olden times, and not so very long ago
+either, everybody knew something about weaving, at least every girl and
+woman knew something of the art, and a loom was as familiar an object in
+the household then as a sewing machine is now.
+
+ Matrons and maidens sat in snow-white caps and in kirtles
+ Scarlet and blue and green, with distaff spinning the golden
+ Flax for the gossiping loom, whose noisy shuttle within doors
+ Mingled their sounds with the whir of the wheels and the
+ songs of the maidens.
+
+This picture of home life in Acadia two hundred years ago would have
+served as a picture of home life almost everywhere in the civilized
+world. From the beginning of history until modern times most of the
+weaving was done by the women in the home.
+
+The earliest practical weaver on record is the spider and it may be that
+man learned his first lesson in weaving from this skilled little workman
+(Fig. 1); or the beautiful nest of the weaver-bird may have given to
+human beings the first hints in the weaving art. Whoever may have been
+his teacher, it is certain that man learned how to weave in the earliest
+stages of existence. It is thought that his first effort in this
+direction consisted in making cages for animals and wiers (traps) for
+catching fish (Fig. 2) by interlacing vines or canes or slender boughs.
+The next step was taken when women began to make baskets and cradles and
+mats by interlacing long slender strips of wood (Fig. 3).

+[Illustration: FIG. 4.--THE PRIMITIVE LOOM.]
+
+Basket weaving led to cloth weaving, and this led to the loom. In Figure
+4 we see the simplest and oldest form of the loom. It consisted of a
+single stick (yarn beam) of wood about four feet long. This was the
+first form of the loom--just a straight stick of wood and nothing more.
+From the stick the threads which run lengthwise in the cloth were
+suspended. These threads are known as the _warp_. The threads which
+run breadthwise in the cloth are known as the _weft_, or _woof_. As the
+woman's deft fingers pass along with the weft she carries the thread
+over the first warp thread, under the second, over the third, under the
+fourth, and so on. Here we have not only the simplest form of the loom
+but the simplest kind of cloth.
+
+[Illustration: FIG. 5.--THE PUEBLO LOOM.]
+
+[Illustration: FIG. 6.--THE HEDDLE.]
+
+In the loom worked by the Pueblo woman (Fig. 5) a new piece appears.
+This is the frame through which the threads of the warp pass and which
+the woman is holding in her right hand. The frame is called a heald, or
+_heddle_ (Fig. 6). The heddle is of the greatest importance in the
+construction of the loom and it is well worth while to understand what
+it does. In the loom operated by the Chilcoot woman (Fig. 4) you noticed
+that the weaver passed the weft thread above and below the alternate
+threads of the warp. This required a separate movement for every thread
+of the warp; if there were a hundred threads a hundred movements were
+required to pass the weft across once. Now the heddle used by the Pueblo
+woman separated the fifty warp threads that were to pass above the weft
+thread from the fifty that were to pass below it, making an opening
+called, a _shed_. When the shed was made the weft thread could be passed
+across at one movement. One movement instead of a hundred! How was this
+accomplished? Fifty alternate warp threads were passed through the holes
+in the bars of the heddle frame, one thread through each hole; the other
+fifty alternate threads passed between the bars of the heddle frame.
+Now suppose the entire warp of a hundred threads is stretched tight and
+firm between the woman's body and the yarn beam. With her right hand she
+_raises_ the heddle and thus lifts the fifty threads which pass through
+the holes in the bars, while the other fifty threads remain unmoved.
+This movement makes the passage or shed through which she passes the
+weft with the left hand. After beating the weft thread close to the
+cloth either with the fingers or with a sword-like stick, she lowers the
+heddle with its fifty threads, the other fifty still remain fixed and
+unmoved. Another shed is formed and the weft is passed through again.
+Thus with the raising and lowering of the heddle the weft is passed
+backward and forward and the weaving goes on quite rapidly. If you care
+to do so you can make a Pueblo loom and can weave a belt on it.
+
+[Illustration: FIG. 7.--AN OLD AFRICAN LOOM.]
+
+In the old African loom represented in Fig. 7 we find several
+improvements upon the loom of the Pueblo woman. In the first place, it
+has two heddles instead of one. These are operated by the feet, leaving
+the hands free to do other work. In the second place, the wooden frame
+which the weaver holds in his right hand is not to be seen in the Pueblo
+loom. This frame called the _batten_, or _lathe_, contains the _reed_,
+which is a series of slats or bars between which the threads of the warp
+pass after they leave the heddle. When the weaver has thrown the weft
+through the shed he brings the batten down hard and the reed drives the
+last weft thread close to the woven part of the cloth. The reed takes
+the place of the sword-like stick used by the Pueblo woman. Last and
+most important: in the African's left hand is the _shuttle_, or little
+car--weaver's ship, the Germans call it--which carries the weft across
+(Fig. 8).
+
+[Illustration: FIG. 8.--A PRIMITIVE SHUTTLE.]
+
+The loom described above seems to be clumsy and rude when compared with
+a loom of the present day, yet it is really the kind of loom which was
+used by nearly all civilized people from the dawn of their civilization
+to the middle of the eighteenth century. It is the loom of history and
+poetry and song. Upon a loom of this kind was woven Joseph's coat with
+its many colors and the garment which the fair Penelope made when she
+deceived her suitors. Of course as the centuries passed the parts of the
+loom were better made and weavers became more skilful. In Figure 9 we
+have the loom as it appeared in the sixteenth century. If we inspect it
+closely we shall find it to be merely the old African loom mounted on
+stout upright timbers instead of being mounted on a tripod made of
+poles. With her feet the weaver works the heddle, with her right hand
+she throws the shuttle, with her left she draws toward her the swinging
+batten and drives the weft home with the reed.
+
+[Illustration: FIG. 9.--A LOOM OF THE SIXTEENTH CENTURY.]
+
+[Illustration: FIG. 10.--KAY'S FLYING SHUTTLE.]
+
+The year 1733 is a most important date in the development of the loom
+for in that year John Kay, a practical loommaker of Lancashire, England,
+invented the flying shuttle and thus did more for the loom than any man
+whom we can distinguish by name. To appreciate the great service of Kay
+we must recall how the shuttle was operated before his time. You
+remember it was thrown through the shed by one of the weaver's hands and
+caught and returned by the other hand. Sometimes it was caught and
+returned by a boy. This was at best a slow process and unless the weaver
+had an assistant to return the shuttle only narrow pieces could be
+woven. The common width of cloth, three-fourths of a yard, had its
+origin in necessity. The weaver's arms were not long enough to weave a
+wider piece. "The essence of Kay's invention was that the shuttle was
+thrown from side to side by a mechanical device instead of being passed
+from hand to hand. One hand only was required for the shuttle while the
+other was left free to beat up the cloth (with the batten) after each
+throw, and the shuttle would fly across wide cloth as well as narrow."
+You will be able to understand Kay's invention by studying Figure 10
+which shows how the flying shuttle worked. _G_ is a groove
+(shuttle-race) on which the shuttle runs as it crosses through the shed
+leaving its thread behind it. _I_ and _I_ are boxes which the shuttle
+(Fig. 11) enters at the end of the journey. In each box is a driver _K_
+sliding freely on the polished rod _F_. The weaver with his right hand
+pulls the handle _H_ and _K_ drives the shuttle to the opposite side.
+With his left hand he works the reed, with his feet he works the heddle.
+
+[Illustration: FIG. 11.--A MODERN SHUTTLE.]
+
+The profits of Kay's invention were stolen, his house was destroyed by a
+mob and he himself was driven to a foreign country where he died in
+poverty. Yet he deserves high rank among the benefactors of mankind, for
+the flying shuttle doubled the power of the loom and improved the
+quality of the cloth woven. Kay's invention was the first step in a
+great industrial revolution. The increased power of the loom called for
+more yarn than the old spinning wheel could supply. Hargreaves and
+Arkwright set their wits to work and made their wonderful spinning
+machine, and the demands of the loom were supplied. So great was the
+supply of yarn that the hand loom was behind with its work. Then in
+order to keep up with the spinning machine the _power-loom_ was
+invented. Heddle and batten and shuttle were now driven by a force of
+nature and all the weaver had to do was to keep the shuttle filled with
+thread and see that his loom worked properly. At first the water-wheel
+was used to drive the power-loom but later the steam-engine was made to
+do this work. All this was changing the face of the civilized world.
+Hitherto weavers and spinners had worked for themselves in their homes
+or in their own shops; now they were gathered in large factories where
+they worked as wage earners for an employer. Hitherto industry had been
+carried on in small villages; the great factories drew the people to
+large industrial centers and the era of crowded cities began.
+
+[Illustration: FIG. 12.--THE JACQUARD LOOM.]
+
+Following the invention of the power-loom in the latter half of the
+eighteenth century came the invention of Joseph Jacquard of Lyons,
+France. This very ingenious man in 1801 invented a substitute for the
+heddle. We cannot readily understand the workings of Jacquard's
+wonderful "attachment," as his substitute for the heddle is called, but
+we ought to know what the great Frenchman did for the loom. In Figure 12
+you see that the cloth which is exposed shows that beautiful designs
+have been woven into it. This is what Jacquard did for the loom. He made
+it weave into the cloth whatever design, color or tint one might desire.
+He made the loom a mechanical artist rivaling in excellence the work of
+a human artist. The Jacquard loom has brought about a revolution in
+man's, and especially in woman's dress. With the old loom, colors and
+designs could be woven into cloth but only very slowly, and goods with
+fancy patterns were made at a cost that was so great that only the rich
+could afford to buy. In the olden times, therefore, almost everybody
+wore plain clothes. With Jacquard's attachment the most beautiful
+figures can be cheaply woven into the commonest fabrics. As far as
+weaving is concerned, it costs no more to have beautiful figures in
+cotton goods than it does to have them in silk. As a result the poor as
+well as the rich can dress as their taste and fancy may suggest.
+
+The last century brought improvements in the weaving art as every
+century before it brought improvements, but the changes made since
+Jacquard's time need not concern us. The story of the loom ends with the
+Jacquard "attachment." Perhaps no other of man's inventions has a more
+interesting development than the loom. We can see it grow, piece by
+piece. First a simple stick from which dangle the threads of the warp;
+then the heddle, then the shuttle, then the reed, then the shuttle-race
+and the swiftly flying shuttle, and last the Frenchman's wonderful
+device for weaving in colors and fancy figures.
+
+
+
+
+THE HOUSE
+
+
+Man has always been a builder. Like squirrels and beavers and birds he
+provides himself a home as by instinct. The kind of house erected by a
+people in the beginning depended upon the surroundings, upon the enemies
+that prowled about, upon the climate, upon the building materials close
+at hand. In a hilly, rocky region primitive folk built one kind of
+house, in a forest they built another kind, in a low marshy district
+they built still another kind. In all cases they took the materials that
+were the easiest to get and erected the kind of dwelling place that
+would afford the greatest safety and comfort.
+
+If one could have traveled over the earth during the first days of man's
+history one would doubtless have found that dwellings were made of wood,
+for in those days the greater part of the earth was covered with
+forests. To build a home in the forest was the simplest of tasks. All
+that was necessary was to fasten together the tops of several saplings,
+interlace the saplings with boughs (Fig. 1) and cover the frame with
+skins of animals or thatch it with leaves and grass. A cone-shaped
+structure of this pattern, a tent, or hut, or wigwam, was the first
+house of all primitive people who lived where there was plenty of wood.
+
+[Illustration: FIG. 1.--BUILDING A HOUSE WITH WOOD.]
+
+[Illustration: FIG. 2.--A CAVE-DWELLING.]
+
+In many regions, especially in parts of northwestern Europe, the wigwam
+or hut was not always the most suitable dwelling place for early man. In
+hilly and mountainous districts and along streams where shores were
+overhung by rocks or pierced by caverns the first inhabitants found that
+a hollow in the earth was the best kind of house. Sometimes the house of
+the cave-dwellers was made by Nature (Fig. 2); sometimes it was an
+artificial living-place dug in the side of a hill or mountain. The cave
+was truly a rude and gloomy home, yet there was a time when large
+numbers of the human race lived in caves. The Zuni Indians of Arizona in
+seeking a refuge from their enemies built their homes far up in steep
+cliffs where it was almost impossible for a stranger to go.
+
+Coming down from the highlands to the lowlands where there were swamps
+and marshes or where inland lakes were numerous, we find that the first
+houses were built upon piles driven in the water or in the mud (Fig. 3).
+These lake-dwellings, as houses of this kind were called, were generally
+connected with the mainland by gangways of wooden piers, although
+sometimes they could be approached only by boat. In the floors of some
+of these curious dwellings were trapdoors through which baskets could be
+lowered for catching fish in the lake below. The children of the
+lake-dwellers were tethered by the feet to keep them from falling into
+the water. The beautiful city of Venice in its infancy was a community
+of lake-dwellers. The rough canoe of the lake-dwelling time has
+developed into the graceful gondola, and the rude wooden pier has grown
+to be the magnificent Rialto.
+
+[Illustration: FIG. 3.--LAKE-DWELLINGS, RESTORED.
+
+(From Troyon.)]
+
+In many regions the most convenient building material is stone and all
+over the earth there are proofs to show that building with stone began
+at a very early date. The stones in the earliest stone structures were
+rough and unhewn and were laid without mortar or cement (Fig. 4) yet
+they were sometimes fitted together with such nicety that a thin knife
+blade could not be passed between them. Remains of stone houses built
+many thousands of years ago may be seen in Peru, Mexico, Italy, and
+Greece. These primitive dwellings were humble and simple, but they were
+made of good material and they were well built. They have weathered the
+storms of ages and they have remained standing while later and more
+pretentious buildings have crumbled and disappeared.
+
+[Illustration: FIG. 4.--A PRIMITIVE STONE HOUSE.]
+
+The illustrations of early building which have been given will make
+plain the truth that the people of a particular country have taken the
+materials nearest at hand and have constructed their homes according to
+their particular needs. Now since the beginnings of house building have
+been different in different parts of the earth, the story of the house
+will not be the same in all countries. In China and Japan, where the
+light bamboo has always flourished and has always been used in building,
+the house has had one development; in countries where granite and marble
+and heavy timber abound it has had another and an entirely different
+development. What then is the story of the house as we see it in our
+country? Can this story be told? As one passes through an American city
+looking at the public buildings and churches and stores and dwellings
+can one go back to the beginning and trace step by step the growth of
+the house and tell how these came to be what they are? Let us see if
+this cannot be done.
+
+[Illustration: FIG. 5.--AN EGYPTIAN HOUSE.]
+
+[Illustration: FIG. 6.--AN ANCIENT HEBREW DWELLING.]
+
+[Illustration: FIG. 7.--INTERIOR OF AN ANCIENT EGYPTIAN PALACE.]
+
+Our story takes us back many thousands of years to Egypt, the cradle of
+civilization. From Egypt it will take us to Greece, thence to Rome,
+thence to the countries of Northern Europe, thence to America. What kind
+of houses did the Egyptians first build? They built as simple a
+structure as can be imagined; they erected four walls and over these
+they placed a flat roof (Fig. 5). The roof was made flat because in
+Egypt there is scarcely any rain and there was no need for a roof with a
+slant. In all those countries where rain seldom falls, or never falls,
+the flat roof is the natural roof (Fig. 6). Although their buildings
+were simple in construction the Egyptians left behind them most
+remarkable specimens of the builder's art. Their pyramids and monuments
+and sphinxes and palaces have always been foremost among the great
+wonders of the world. Figure 7 shows the interior of an ancient Egyptian
+palace. This palace had only an awning for a roof. That was all that was
+necessary to keep out the rays of the sun. Notice the lofty pillars or
+columns of this building. You see they are adorned above or below with
+the figure of the lotus, the national flower of the Egyptians. The
+column, as we shall see, plays an important part in the history of the
+house and it was ancient Egypt that gave the world its first lessons in
+the art of making columns.
+
+From Egypt we pass over "the sea" to Greece. The Greeks borrowed ideas
+wherever they could and in the matter of architecture they borrowed
+heavily from Egypt. But they did not borrow the flat roof of the
+Egyptians. In Greece there was some rainfall and this fact had to be
+taken into account when building a house; the roof had to slant so that
+the rain could run off. Now the Greeks taught the world the best way to
+make a slanting roof. They made the roof to slant in two directions from
+a central ridge (Fig. 8) instead of having the entire roof to slant in
+one direction like an ugly shed. The slant was gentle because there was
+no snow to be carried off. The roof of two slants formed a gable. The
+Greeks, then, were the inventors of the _gable_. The column they
+borrowed from Egypt. But whenever the Greeks borrowed an invention or
+an idea they nearly always improved upon it. Instead of slavishly
+imitating the Egyptian columns they tried to make better ones and they
+were so successful that they soon became the teachers of the world in
+column making.
+
+[Illustration: FIG. 8.--A GREEK DWELLING.]
+
+[Illustration: FIG. 9.--THE THREE ORDERS OF COLUMNS.]
+
+The oldest and strongest of the Greek columns belong to what is known as
+the Doric order (Fig. 9), a name given to them because they were first
+made by the Dorians, the original Greek dwellers in Europe. Aside from
+the flutes or channels which ran throughout its length the Doric column
+was perfectly plain. In the older Doric columns even the flutes are
+absent. Its _capital_ or top, was without ornament. Later the graceful
+and elegant Ionic pillar (Fig. 9) came into fashion. We can always
+distinguish an Ionic column by the volute or scroll at its capital. The
+latest of the Greek columns was the Corinthian (Fig. 9), the lightest,
+the most slender and the most richly decorated of all. A cluster of
+acanthus leaves at its capital is the most prominent ornament of the
+Corinthian column. The Greeks carried the art of column making to such
+perfection that even to this day we imitate their patterns. A column in
+a modern building is almost certain to be a Greek column. It is worth
+one's while, therefore, to be able to tell one Greek column from
+another. One can do this by remembering (1) that the Doric column is
+perfectly plain and has no capital; (2) that the Ionic column has a
+scroll at the capital; (3) that the capital of the Corinthian column is
+adorned with a cluster of acanthus leaves.
+
+[Illustration: FIG. 10.--AN OLD ROMAN ARCH.]
+
+Our story now takes us to Italy. Greece fell before the power of Rome
+146 B.C., but before she fell she had taught her conquerors a great deal
+about architecture. Indeed the Romans took up the art of building where
+the Greeks left it. They needed the Greek gable for they had rains, and
+the Greek column recommended itself to them on account of its beauty.
+They used the best features of Grecian architecture and added a feature
+that was largely their own. This was the _arch_. The Greeks, like the
+Egyptians before them, bridged over the openings of doors and windows
+and the spaces between columns by means of straight wooden beams or long
+blocks of stone. The Romans bridged over these spaces with the arch
+(Fig. 10). If you will study the arch you will see that it is a curved
+structure which is supported by its own curve. You will also see that it
+is a structure of great strength. The greater the weight placed upon it,
+providing its bases are supported, the stronger it gets. In teaching the
+world how to make arches Rome added to the house an element of great
+strength and beauty. With the arch came the tall building. In Greece a
+house was never more than two stories high. In Rome arch rose upon arch
+(Fig. 11); the dome which is itself a kind of arch appeared and palaces
+were piled story upon story until they seemed to reach the skies.
+
+From Italy we pass to northern Europe. The power of Rome fell 476 A.D.,
+but before that date the greater part of Europe had been Romanized, and
+the Roman way of building with column and arch and dome had been learned
+in France and Germany and England. But the climate of those countries
+was different from that of Italy and a slight change in the Roman way of
+building was necessary. In the northern countries there were heavy rains
+and snows and a roof with a gentle slope was not suitable for carrying
+off large quantities of water and snow. A gable (Fig. 12) with a sharp
+slant was necessary. Hence throughout northern Europe the roofs were
+built much steeper than they were in Italy and Greece, although in other
+respects the northern houses resembled more or less closely those of the
+older southern countries.
+
+[Illustration: FIG. 11.--INTERIOR OF A ROMAN CLUB HOUSE.]
+
+[Illustration: FIG. 12.--A DWELLING IN NORTHERN EUROPE.]
+
+The pointed roof which was made necessary by the climate of the north
+prepared the way for a new style of building, the _pointed_ or _Gothic_
+style. This style began to appear in the twelfth century and by the end
+of the thirteenth century--that remarkable century again--the buildings
+of all northern Europe were Gothic. The new style began with a change in
+the arch. The Roman arch was a semi-circle and was therefore described
+from one center. The Gothic arch was formed by describing it from two
+centers instead of one and was therefore a pointed arch. As the pointed
+arch grew in favor it became the fashion to shape other parts of the
+building into points wherever it was possible to do this. The rounding
+dome became a spire "pointing heavenward"; the windows and doors were
+pointed and so were the ornaments and decorations. For several centuries
+buildings fairly bristled with points (Fig. 13). The finest example of
+Gothic architecture is the glorious cathedral at Cologne.
+
+[Illustration: FIG. 13.--POINTED STYLE.
+
+Typical scheme of a fully developed French cathedral of the 13th
+century. (From Viollet-le-Duc's "Dict. de l'Architecture.")]
+
+During the thousand years of the Dark Ages (476-1453) the glories of the
+civilization of ancient Greece and Rome faded almost completely from
+human vision. Events of the sixteenth century brought those glories
+again into view and Europe was dazzled by them. Men everywhere became
+dissatisfied with the things around them. They longed for ancient
+things. They read ancient authors, they imitated ancient artists, they
+imbibed the wisdom of ancient teachers. This was the period of the
+Renaissance, the time when the world was born anew--as it pleased men to
+think and say. The world of the present died and the old world of Greece
+and Rome was brought to life. Of course in the new order of things
+architecture underwent a change. _It_ was born again; _it_ experienced a
+renaissance. The pointed style grew less pleasing to the builder's eye,
+and wherever he could he placed in his building something that was Greek
+or Roman, here an arched doorway, there a Greek column. There resulted
+from these changes a style that was neither Gothic, Grecian nor Roman,
+but a mixture of all these. This mixed style was named after the period
+in which it arose. When you see a building that strongly resembles the
+buildings of ancient Greece and Rome and at the same time has features
+which belong to other styles you may safely say that the building
+belongs to the renaissance style. (Fig. 14.) The most noble and
+beautiful examples of renaissance architecture are the church of St.
+Peter's at Rome and the church of St. Paul at London.
+
+[Illustration: FIG. 14.--A RENAISSANCE DWELLING.]
+
+We now pass over to America. About the time the old world was born anew
+the new world was found. The houses of the first settlers in America
+were of course rude and ugly but as the colonies grew in population and
+wealth more expensive and beautiful houses were built. As we should
+expect, the colonists built their best houses in the style that was then
+in fashion in the old world and that was the renaissance style. They did
+not, however, copy the old world architecture outright. They had
+different materials, a different climate and a different class of
+workmen and they had to build according to these changed conditions. The
+result was a style of building that has been called colonial (Fig. 15).
+Colonial architecture was simply American renaissance. And that is what
+it is to-day. To say that a house is in the colonial style is to say
+that it represents a certain architect's ideas as to what is best and
+most beautiful in all styles.
+
+[Illustration: FIG. 15.--A COLONIAL MANSION.
+
+The Cliveden Chew Mansion, where the Battle of Germantown was fought.]
+
+The story of the house really ends with the period of the renaissance.
+Since the sixteenth century nothing really new in architecture has been
+discovered and men have been wedded to no particular style. When we want
+to build a house we choose from all the styles and build according to
+our tastes. Our story of the house, however, will not be complete
+without a brief account of what has been called _elevator_ architecture.
+The high price of land in large cities makes it necessary to run
+buildings up to a considerable height if they are to be profitable. Now
+if a building is more than five stories high it must have an elevator,
+or lift, and if an elevator is to be put in, the building might as well
+be run up nine or ten stories. American business men learned this
+thirty or forty years ago and began to build high, and they have been
+building higher and higher ever since. There are tall buildings in other
+countries but the "sky-scraper" of twenty-five and thirty stories is
+found only in the United States (Fig. 16).
+
+[Illustration: (Copyright 1911 by Underwood & Underwood, N. Y.)
+
+FIG. 16.--ELEVATOR ARCHITECTURE.
+
+The tower-like structure in the distance is a building more than forty
+stories in height.]
+
+Thus we may see in the house of to-day a long and unbroken story. Where
+the roof is flat it is Egyptian; where it slants gently in two
+directions it is Greek; where it is steep or sharply pointed it is
+Gothic. The columns are Greek, the rounded arches are Roman. The whole
+is the result of the thousands of years of effort which man has given to
+the task of providing for himself a safe, convenient and beautiful
+home.
+

+
+
+THE CARRIAGE
+
+
+We are very proud in our day of our means of transportation. If one
+wishes to send a present to a friend a thousand miles away a few cents
+spent in postage will take the article to its destination. If for the
+sake of higher prices a fruit grower wishes to sell his crops in a
+distant city, the railroad people will haul it for him at a very small
+cost. If you wish to visit a friend in town several blocks away, there
+is the electric car ready to take you for a nickel. If your friend is
+several hundred miles away, the steam car will take you in a few hours
+at a cost of not more than two or three cents a mile. I am living in the
+country sixteen miles from the city in which my work lies, and for nine
+cents I am carried to the place of my business in less than
+half-an-hour. What has been the history of the inventions which make
+transportation so comfortable, rapid and cheap? Our subject divides
+itself into two parts, transportation on land and transportation on
+water or the story of the Carriage and the story of the Boat. We will
+have the story of the carriage first.
+
+Man's only carriage at first was of course his own feet. When he wanted
+to go to any place he had to take "Walker's hack," if a playful
+expression may be pardoned. As a traveler on foot, man soon surpassed
+all other animals. He could walk down the deer and wear out the horse.
+When it came to carrying things from place to place, in the beginning he
+had to rely upon his own limbs and muscles. It was not long, however,
+before he learned that there were good ways and bad ways of carrying
+things, and he soon set about finding the best way. We may believe that
+he began by making a snug bundle and carrying it on his shoulder. Then
+he found that he could carry a heavier burden upon his back, and he
+invented a pack or frame on which he could carry things on his back
+(Fig. 1) after the manner of one of our modern pack peddlers.
+
+[Illustration: FIG. 1.--A HUMAN BURDEN BEARER.
+
+(From a Model in National Museum.)]
+
+In the course of time man tamed one or more of the wild beasts which
+roamed near him. Then the burden was shifted from the back of a man to
+the back of a beast. The first beast of burden in South America was the
+llama; in India it was the elephant; in Arabia it was the camel (Fig.
+2). In Europe and in parts of Asia and in Egypt the horse first became
+man's burden bearer and the nations which had the services of this swift
+and strong animal outstripped the other nations of the world. "Which is
+the most useful of animals?" asked one Egyptian god of another. "The
+horse," was the reply, "because the horse enables a man to overtake and
+slay his enemy."
+
+[Illustration: FIG. 2.--A SHIP OF THE DESERT.]
+
+[Illustration: FIG. 3.--A CART WITHOUT WHEELS.
+
+(From a Model in the National Museum.)]
+
+It is often easier to drag a thing along than it is to carry it. This
+fact led to the invention of what we may call the first and simplest
+form of carriage. This was the drag or travail (tra-vay´), a cart
+without wheels (Fig. 3). Two long saplings were fastened at the large
+end to the strap across the horse's breast and the small end upon which
+the burden was placed dragged upon the ground. Mr. Arthur Mitchell in
+his delightful book, "The Past in the Present," tells us that he saw
+carts of this kind in actual use in the highlands of Scotland as late as
+1864! An improvement upon the travail was the sledge made of the forked
+limb of a tree (Fig. 4). This primitive sledge was really a travail
+consisting of one piece.
+
+[Illustration: FIG. 4.--A PRIMITIVE SLEDGE.

+
+In many cases it is easier to roll a thing than it is to drag it. This
+fact led to another step in the development of the carriage; it led from
+the cart without wheels to a cart with a wheel--a most important step in
+the history of inventions. The first wheeled cart was simply a log from
+each end of which projected an axle (Fig. 5). The axle fitted in the
+holes of a frame upon which the body of the cart was placed and to which
+the horse or the ox was attached. As the cart moved along, wheel (log
+and axle) turned together. The very ancient method of moving a load by
+rolling it along was in use in the United States not so very long ago.
+As late as 1860 in some of the southern States hogsheads of tobacco
+(Fig. 6) were rolled over country roads in the manner just described and
+as late as 1880 the fishermen of Nantucket used as a fish cart a vehicle
+that had only a barrel for its wheel. (Fig. 7.) The common wheel-barrow
+and the one-wheeled carts which are still used in China and Japan had
+their origin in the rolling log.

+
+We are told by some writers that the rolling log (the one-wheeled cart)
+was followed by the two-wheeled cart, on which the wheels were the ends
+of a log and the axle was the middle portion of the log hewn down to a
+proper size (Fig. 8). Here wheels and axle turned together precisely
+like a modern car wheel. This makes a very pretty story but I am afraid
+the solid two-wheeled affair represented in Figure 8 is only imaginary,
+and that in a true account of the development of the cart it has no
+place. The true beginning of the two-wheeled cart may be learned from
+Figure 9. Here the wheels are two _very short_ logs through the center
+of which are holes in which the round ends (axles) of a piece of timber
+(the axle-tree) fit. When the cart moves, the wheels turn upon the axle.
+The one-wheeled cart had at first _one log_ turning _with_ the axle;
+the two-wheeled cart at first had as its wheels two very short logs
+turning _on_ the axles.
+
+[Illustration: FIG. 8.--A CART WITH WHEELS AND AXLE IN ONE PIECE.]
+
+[Illustration: FIG. 9.--CART WITH A SOLID WHEEL.]
+
+[Illustration: FIG. 10.--CART WITH WHEEL PARTLY SOLID.
+
+(From a Model in the National Museum.)]
+
+The first two-wheeled carts were a great improvement upon the single
+rolling log, yet they were exceedingly heavy and clumsy. The trouble was
+with the wheel. This was very thick and with the exception of the hole
+in which the axle went it was entirely solid. Wheelwrights at a very
+early date saw that the problem was to make the wheel light and at the
+same time to keep it strong. Little by little this problem was solved.
+At first crescent-shaped holes were made in the wheel (Fig. 10). This
+made the wheel lighter, but did not weaken it. In its next form the
+wheel was even less solid than before. It now consisted of four curved
+pieces of wood (Fig. 11) held together by four spokes. In this wheel
+there was a hub, but the spokes were not inserted in it; they were
+fastened about it. In the Egyptian chariot (Fig. 12) we find the wheel
+in the last stage of its interesting and remarkable development. Here
+the spokes, six in number, are inserted in the hub from which they
+radiate to the six pieces of the felly or inner rim. Around the felly
+is the outer rim or tire made of wood and fastened to the felly with
+thongs. The wheel of to-day has more iron in it, and has more spokes and
+is lighter and stronger than the old Egyptian wheel, yet in its main
+features it is made like it.
+

+
+A light running two-wheeled carriage was used by all the civilized
+nations of the ancient world. Three thousand years ago in the great and
+wicked city of Nineveh chariots raced up and down the paved streets
+"jostling against one another in the broad ways, with the crack of the
+whip, the rattle of the wheel and the prancing of horses." The chariot
+played an important part in the life of the Greeks and Romans, in their
+racing contests and in their wars, and throughout the Middle Ages it
+was the only vehicle in general use in Europe. As time passed it was of
+course made lighter and stronger and better. The doctor's gig so
+charmingly described by Holmes in his "Wonderful One Hoss Shay" may be
+taken as an illustration of the full development of the two-wheeled
+carriage (Fig. 13).
+
+[Illustration: FIG. 14.--AN ANCIENT ROMAN CHARIOT.]
+
+Bring the hind part of one Egyptian chariot opposite to the hind part of
+another, lash the two chariots together, remove the tongue of one of the
+chariots and you have made a chariot of four wheels or a _coach_. The
+form of the most ancient of four-wheeled carriages leads to the belief
+that the coach was first made by joining together two two-wheeled
+chariots in the way just described. The ancient Egyptians had their
+four-wheeled chariots but only their gods and their kings had the
+privilege of riding in them. For centuries none but the great and the
+powerful rode in coaches. The Roman chariot (Fig. 14), bad imitations of
+which we see nowadays in circus processions, was used only in the
+splendid triumphal processions which entered Rome after a great victory.
+In the Middle Ages we get a glimpse of a four-wheeled carriage now and
+then, but usually the king or a queen is lounging in it (Fig. 15). The
+coach could not be generally used in Europe in medieval times because
+the roads were so bad. The excellent roads made by the Romans had not
+been kept in good condition. Traveling had to be done either on
+horseback or in the two-wheeled carriage. In 1550 there were but three
+coaches in Paris and in London there was but one. In 1564, however, we
+find Queen Elizabeth riding in a coach (Fig. 16) on her way to see her
+lover, Lord Leicester. Insert more spokes and lighter ones in the
+wheels of this coach of the queen's, put on rubber tires and mount the
+body on elliptical springs[17] and we will have the coach of to-day.

+[17] About the year 1700 elliptical springs were invented, but they did
+not find their way into general use until more than a hundred years

+
+THE CARRIAGE
+
+_Continued_
+
+
+[Illustration: FIG. 1.--NEWTON'S STEAM CARRIAGE, 1680.]
+
+In the last chapter the story of the Carriage was brought up to the
+reign of Queen Elizabeth of England. In the century following
+Elizabeth's reign a new and most remarkable step in the development of
+the carriage was taken. You remember that in the seventeenth century
+there was a great deal of experimenting with steam (p. 58). Among other
+experiments was one made by Sir Isaac Newton. This great philosopher
+tried in 1680 to make a steam-carriage, or _locomotive_, as we call it.
+Figure 1 shows the principle upon which he tried to make his carriage
+work. The steam was to react against the air, as in the case of Hero's
+engine (p. 56) and thus push the carriage along. Newton's experiment was
+not satisfactory but the idea of a steam-carriage was now in men's heads
+and the hope of making one continued to be cherished. In 1769 Cugnot, a
+French army officer, invented a steam-carriage of three wheels (Fig. 2)
+but it was a very poor one. It traveled only three or four miles an
+hour, it could carry but three persons, and it had to stop every ten
+minutes to get up steam. Cugnot, however, deserves to be ranked among
+the great inventors for he showed that a steam-engine could be attached
+to a carriage and could push it along. In other words he showed that
+steam could be used for transportation as well as for working pumps and
+turning the wheels of factories. And that was just what was needed most
+in the latter part of the eighteenth century. Man needed assistance in
+traveling; he especially needed help in carrying things from place to
+place. The steam-engine was keeping the mines dry and making it possible
+to mine great quantities of coal and was turning the wheels of great
+factories where the spinning-jenny and the new power loom (p. 119) were
+consuming enormous quantities of cotton and wool. Now if the
+steam-engine could also be made to carry the coal and cotton and wool to
+the factory, and the manufactured products from the factory to the
+market, the industrial revolution would be complete indeed.
+
+[Illustration: FIG. 2.--CUGNOT'S STEAM CARRIAGE, 1769.]
+
+Inventors everywhere put their wits together to construct an engine that
+would draw a load. The great Watt tried to make one, but having failed,
+he came to the conclusion that the steam-engine could do good work only
+when standing still. Among those who entered the contest was Richard
+Trevithick, a Cornish miner, born in 1771. Trevithick when a lad at
+school was able to work six examples in arithmetic while his teacher
+worked one. He proved to be as quick in mechanics as he was in
+mathematics. He began his experiments with steam when a mere boy, and as
+early as 1796 he had built a steam-locomotive which would run on a
+table. By 1801 he had constructed a steam-carriage (Fig. 7). Three years
+later (1804) Trevithick exhibited a locomotive which carried ten tons of
+iron, seventy men, and five wagons a distance of nine and one-half miles
+at the rate of five miles an hour. This was the first steam carriage
+that actually performed useful work. The honor of inventing the first
+successful locomotive, therefore, belongs to Richard Trevithick,
+although he never received the honor that was due him.
+
+The honor went to George Stephenson, of Wylam, near Newcastle, England.
+Stephenson's parents were so poor that they could not afford to send him
+to school long enough for him to learn to read and write. In his
+eighteenth year, however, he attended a night school and learned
+something of the common branches. In his childhood Stephenson lived
+among steam-engines. He began as an engine boy in a colliery and was
+soon promoted to the position of fireman. At an early age he was trying
+to build the locomotive that the world needed so badly, one that would
+do good work at a small cost. Trevithick's locomotive was too expensive.
+Stephenson wanted a locomotive that would pay its owner a profit. At the
+age of thirty-three he had solved his problem. In 1814 he exhibited a
+locomotive that would run ten or twelve miles an hour and carry
+passengers and freight cheaper than horses could carry them. Eleven
+years later he was operating a railroad between Stockton and Darlington,
+England. The steam carriage was now a success (Fig. 3). The iron horse
+was soon transporting passengers and freight in all the civilized
+countries of the world (Fig. 4). Observe that the first passenger car
+was simply the old coach joined to a locomotive.
+
+[Illustration: FIG. 3.--STEVENSON'S LOCOMOTIVE, 1828.]
+
+[Illustration: FIG. 4.--THE "BEST FRIEND." THE FIRST LOCOMOTIVE BUILT
+FOR ACTUAL SERVICE IN THE UNITED STATES.]
+
+The locomotive worked wonders in travel and in carrying loads, yet men
+were not satisfied with it. We never are satisfied with our means of
+transportation. No matter how comfortably or cheaply or fast we may
+travel we always want something better. In the latter part of the
+nineteenth century the great cities of the world were becoming
+over-crowded. The people could not be carried from one part of a city
+to another without great discomfort. The street cars drawn by horses
+could not carry the crowds and the elevated steam cars were not
+satisfactory. Wits were set to work to relieve the situation and about
+thirty years ago the _electric car_ (Fig. 5) was invented. Without horse
+or locomotive this quick-moving car not only successfully handles the
+crowds which move about the city but it also relieves over-crowding by
+enabling thousands to reach conveniently and cheaply their suburban
+homes. It also does the work of the steam car and carries passengers
+long distances from city to city.
+
+[Illustration: FIG. 5.--A TROLLEY CAR.]
+
+[Illustration: FIG. 6.--A HORSELESS CARRIAGE OF THE SIXTEENTH CENTURY.]
+
+A late development in carriage making is seen in the automobile. As far
+back as the sixteenth century a horseless carriage was invented (Fig. 6)
+and was operated on the streets of a German city. But here the power was
+furnished by human muscle. The first real automobile (Fig. 7) was
+invented in 1801, by the man who invented the first successful
+locomotive. Trevithick's road locomotive--for that is what an automobile
+really is--did not work well because the roads upon which he tried it
+were in very bad condition. Inventors after Trevithick for a long time
+paid but little attention to the road locomotive; they bestowed their
+best thought upon the locomotive that was to be run upon rails--the
+railroad locomotive. In recent years, however, they have been working on
+the so-called automobile and they have already given us a horseless
+carriage that can run on a railless road at a rate as great as that of
+the fastest railroad locomotives. To what extent is this newest of
+carriages likely to be used? It is already driving out the horse. Will
+it also drive out the electric car and the railroad locomotive? Are we
+coming to the time when the railroad will be no more and when all travel
+and all hauling of freight will be done by carriages and wagons without
+horses on roads without rails? The answers to these questions can of
+course only be guessed.
+
+[Illustration: FIG. 7.--THE FIRST AUTOMOBILE.]
+
+[Illustration: FIG. 8.--GOOD-BY TO THE HORSE.]
+
+The last and latest form of the carriage is seen in the
+_flying-machine_, the automobile of the air. In all ages men have
+watched with envy the movements of birds and have dreamed of
+flying-machines, but only in modern times has man dared to take wings
+and glide in bird-like fashion through the air. The first actual flying
+by a human being was done by a Frenchman named Bresnier, who, in 1675,
+constructed a machine similar to that shown in the right hand picture
+at the top of Figure 9. Bresnier worked his wings with his feet and
+hands. Once he jumped from a second story window and flew over the roof
+of a cottage. From the days of Bresnier on to the present time man has
+taxed his wits to the utmost to conquer the air, and in his efforts to
+do this he has invented almost every conceivable kind of machine. About
+the middle of the nineteenth century inventors began to apply steam to
+the flying-machine, and it is said that in 1842 a man named Philips was
+able, by the aid of revolving fans driven by steam, to elevate a machine
+to a considerable distance and fly across two fields. In 1896 Professor
+Langley, with a flying-machine driven by a small steam-engine, made
+three flights of about three-fourths of a mile each over the Potomac
+River, near Washington. This was the first time a flying-machine was
+propelled a long distance by its own power; it was the first aerial
+automobile. But the aerial steam carriage was never a success; the steam
+engine was too heavy. In the early years of the twentieth century
+inventors began to use the light gasoline engine to drive their
+flying-machines and then real progress in the art of flying began, and
+so great has been that progress that the automobiles of the air are
+becoming rivals of those on the land.
+
+[Illustration: FIG. 9.--SOME UNSUCCESSFUL FLYING MACHINES OF A HUNDRED

+
+
+
+
+THE BOAT
+
+
+[Illustration: FIG. 1.--THE FIRST BOAT.]
+
+At first, when a man wanted to cross a deep stream, he was compelled to
+swim across. But man at his best is a poor swimmer, and it was not long
+before he invented a better method of traveling on water. A log drifting
+in a stream furnished the hint. By resting his body upon the log and
+plashing with his hands and feet he found he could move along faster and
+easier. Thus the log was the first boat and the human arm was the first
+oar. Experience soon taught our primitive boatman to get on top of the
+log and paddle along, using the limb of a tree for an oar (Fig. 1). But
+the round log would turn with the least provocation and its passenger
+suffered many unceremonious duckings. So the boatman made his log flat
+on top. It now floated better and did not turn over so easily. Then the
+log was made hollow, either by burning (Fig. 2), or by means of a
+cutting instrument. Thus the canoe was invented. Very often if the
+nature of the tree permitted it, the log was stripped of its bark, and
+this bark was used as a canoe.
+
+[Illustration: FIG. 2.--THE INVENTION OF THE CANOE.]
+
+[Illustration: FIG. 3.--THE RAFT--SHOWING ALSO EARLY USE OF THE SAIL.]
+
+[Illustration: FIG. 4.--A PRIMITIVE OARLOCK.]
+
+The canoe was one of the earliest of boats, but it is not in line with
+the later growth. The ancestry of the modern boat begins with the log
+and is traced through the raft rather than through the canoe. By lashing
+together several logs it was found that larger burdens could be carried.
+Therefore the boat of a single log grew into one of several logs--a raft
+(Fig. 3). By the time man had learned to make a raft he had learned
+something else: he had learned to row his boat along by pulling at an
+oar instead of pushing it along with a paddle. But in order to row there
+must be something against which the oar may rest; so the oarlock (Fig.
+4) was invented. Rafts were used by nearly all the nations of antiquity.
+Herodotus, the father of history, tells us that they were in use in
+ancient Chaldea. In Figure 3 we have a kind of raft that may still be
+seen on some of the rivers of South America. Here a most important step
+in boat-building has been taken. A _sail_ has been hoisted and one of
+the forces of nature has been bidden to assist man in moving his boat
+along.
+
+The raft was bound to develop into the large boat. The central log was
+used as a keel and about this was built a boat of the desired shape and
+size. Stout timbers, called ribs, slanted from the keel, and on the ribs
+were fastened planks running lengthwise with the vessel. To keep out the
+water the seams between the planks were filled with pitch or wax. Thus
+the raft grew into a large spoon-shaped vessel (Fig. 5). The early boat
+was usually propelled by oars, although a single sail sometimes invoked
+the assistance of the wind. It had no rudder and no deck, and if there
+was an anchor it was only a heavy stone.
+
+[Illustration: FIG. 5.--"THUS THE RAFT GREW INTO A LARGE, SPOON-SHAPED
+VESSEL."]
+
+In the early history of the boat there was no such thing as a rudder.
+The oarsman had to steer his craft as best he could. With the
+appearance of larger boats, however, a steersman comes into view. He
+steers by means of a paddle held over the stern of the boat. Within
+historic times, probably about the time of Homer (1100 B. C.), the
+rudder appears as an oar with a broad blade protruding through a hole in
+the side of the boat well to the stern (Fig. 6). Throughout the whole
+period of ancient history boats were steered by rudders of this kind.
+
+[Illustration: FIG. 6.--THE POSITION OF THE RUDDER IN ANCIENT TIMES.]
+
+[Illustration: FIG. 7.--ANCIENT ANCHORS.]
+
+The anchor came later than the rudder. Of course even in primitive times
+there were methods of securing the vessel to the ground under water but
+they were very crude. Sometimes a sack of sand was used as an anchor,
+sometimes a log of wood covered with lead was thrown overboard to hold
+the boat in its place. In Homer's time the anchor was a bent rod with a
+single fluke. About 600 B. C. Anacharsis, one of the seven wise men of
+Greece, gave a practical turn to his wisdom and invented an anchor with
+two flukes (Fig. 7). The invention received the name of "anchor" from
+the name of the inventor.
+
+[Illustration: FIG. 8.--A ROMAN GALLEY OF ONE TIER OF OARS, INTRODUCING
+THE RUDDER.]
+
+It was in the Mediterranean Sea that the boat had its most rapid
+development. As early as we can get a glimpse of that wonderful body of
+water it was alive with boats (called galleys) that had well-laid keels
+and lofty sides, and rudders, and sails. The greatest of the earlier
+navigators were the Phoenicians whose boats had traversed 5,000 years
+ago the whole course of the Mediterranean and had even ventured beyond
+the Straits of Gibraltar. The ancient Greeks also were a great sea-going
+people, and their merchantmen or trading boats visited every part of the
+known world. But it was the Romans who at last became masters of the
+ancient seas. The Roman galley, therefore, may be taken as the
+representative boat of ancient times. What kind of a boat was the Roman
+galley? It was propelled chiefly by oars, just as nearly all the boats
+of antiquity were. Occasionally a sail was hoisted when the wind was
+favorable but the main reliance was the rower's arm. Men had not yet
+learned to use the sail to the best advantage. The older galleys had one
+row of oarsmen (Fig. 8), but as the struggle for the mastery of the sea
+became keener the boats were made larger and more rowers were necessary.
+Galleys with two and three, and even four rows of oarsmen were built by
+the Roman navy. When there was more than one row of oars the rowers sat
+on benches one above another. The oarsmen were slaves or prisoners
+captured in war, and their life was most wretched.[18] They were chained
+to the benches on which they sat, and were compelled to row as long as a
+spark of life was left. Sometimes they dipped their oars to the music of
+the flute, but more often it was to the crack of the lash. Figure 9
+shows us how the Roman galley looked when Rome was at the height of her
+power (100 A. D.). Here is a vessel about 400 feet long and about 50
+feet across its _deck_, a part of the boat, by the by, which was not to
+be seen in the earlier galleys. The boat is a trireme, that is, it has
+openings for three tiers of oars, and it is propelled by several hundred
+oarsmen. For steering purposes it has four stout paddles, two on each
+side near the stern. Two masts instead of one carry the sail which,
+considering the size of the boat, would seem to be insufficient. This
+galley of the first century of our era represents the full development
+of the boat in ancient times.
+
+[Illustration: FIG. 9.--A ROMAN GALLEY WITH THREE BANKS OF OARS.]
+
+After the downfall of Rome (476 A. D.) it was a long time before there
+was any real progress in boat-making. The glimpses we get now and then
+of vessels in the Middle Ages almost make us feel that boat-building was
+going backward rather than forward. But such was not the case. The ship
+in which William of Normandy sailed (Fig. 10) when he crossed over the
+Channel to give battle to Harold (1066 A. D.) was not so impressive as a
+Roman galley, yet it was, nevertheless, a better boat. In the first
+place William's boat was a better sailer; it relied more upon the force
+of the wind and less upon the oar. In the second place, it could be
+steered better, for the rudder had found its way to its proper place and
+was worked by a tiller. Finally, the shape of the Norman boat fitted it
+for fiercer battles with the waves.
+
+[Illustration: FIG. 10.--THE SHIP IN WHICH WILLIAM THE CONQUEROR CROSSED
+THE CHANNEL IN 1066.]
+
+[Illustration: FIG. 11.--A MEDITERRANEAN GALLEY OF THE 14TH CENTURY.]
+
+If we should pass from the English Channel to the Adriatic we should
+find that boat-making had undergone the same changes. A Mediterranean
+galley of the fourteenth century (Fig. 11) shows fewer oars and more
+sails. Instead of three rows of oars and two sails as on the Roman
+galley, there are three sails and one row of oars. This was the tendency
+of the boat-builder in the Middle Ages; he crowded on the sail and took
+off the rowers. A war-boat of the sixteenth century (Fig. 12) shows that
+the last row of oarsmen has disappeared.
+
+[Illustration: FIG. 12.--A WAR-BOAT OF THE 16TH CENTURY, SHOWING THAT
+THE LAST ROW OF OARS HAD DISAPPEARED.]
+
+[Illustration: FIG. 13.--A CHINESE COMPASS. AS THE CART MOVED THE HUMAN
+FIGURE IN FRONT ALWAYS POINTED NORTH.]
+
+About the middle of the thirteenth century there began to appear on the
+decks of vessels almost everywhere in Europe, a little instrument that
+is of the greatest importance in the history of the boat. This was the
+_mariner's compass_. The use of the magnetic needle was known in China
+(Fig. 13) a thousand years before it was known to the Europeans, but in
+this, as in many other instances, the Chinese did not profit by their
+knowledge. Sailors have always sailed at night by the North star; but
+before the use of the compass was understood they could little more than
+guess their way when the night was dark and the stars could not be seen.
+With a mariner's needle on board they can tell the direction they are
+going no matter how dark the night. We can easily understand that
+sailors prized very highly the discovery of the compass. With the
+appearance of this faithful guide they became bolder and bolder and were
+soon venturing out upon the trackless expanse of the ocean. It was the
+compass that led to the discovery of the new world, for without it no
+sailor could have held his course due west long enough to reach the
+American coast.
+
+After men had learned to carry their burdens on the broad back of the
+ocean, boat-building took on new life. All the great nations of Europe
+wanted a share in the new world that had just been found; but no nation
+could hope to profit greatly by the discovery of Columbus if its vessels
+were not swift and strong. So there arose a grim contest for the mastery
+of the Atlantic, just as in ancient times there had been a struggle for
+the mastery of the Mediterranean. Spain, France, Portugal, Holland and
+England all joined in the battle. When we see the kind of boats she sent
+out upon the oceans we are not surprised that England won. Compare the
+heavy, angular galley of the first century with the graceful ship of the
+sixteenth century and we see at once the progress the boat made in the
+Middle Ages (Fig. 14).
+
+[Illustration: FIG. 14.--THE GREAT HARRY.]
+
+The log, the raft, the galley, the sailing-ship, these were the steps in
+the development of the boat up to the end of the seventeenth century. In
+the eighteenth century another step was taken. You remember that in that
+century inventors were everywhere trying to make a steam carriage. They
+were at the same time trying to make a steam boat. Their efforts to use
+steam to drive boats were rewarded with success earlier than were their
+efforts to use it to draw carriages. This was to be expected.
+Boat-building has always moved along faster than carriage-building. Men
+were gliding about in well-built canoes before they had even the
+clumsiest of carts. The Londoners who gazed with admiration upon the
+_Great Harry_ as it sailed on the Thames, had never seen as much as a
+lumbering coach. And so with the steamboat; it had crossed the Atlantic
+before the locomotive could carry passengers from one town to the next.
+
+France, England, Germany and America were all eager to have the first
+steamboat. In this race America won, although France and England came
+out with their colors flying. As far back as 1663 the Marquis of
+Worcester, of whom we have heard before (p. 59), described a vessel that
+could be moved by steam: "It roweth," he said, "it draweth, it driveth
+(if needs be) to pass London bridge against the stream at low water." It
+was one thing, however, to describe a steamboat, and quite another thing
+to make one. Worcester's steam-vessel existed only in the imagination of
+the inventor. Denys Papin, who did so much for the steam-engine, fitted
+out a boat with revolving paddles which were turned by horses. This was
+nothing new. The ancient Roman galley was sometimes propelled by
+paddle-wheels turned by horses or oxen. It is sometimes claimed that
+Papin turned the paddle-wheels of his boat by means of steam, but there
+are no grounds for the claim. If France wants the honor of having made
+the first steamboat she would do better to turn from Papin and look to
+Marquis of Jouffroy of Lyons, This nobleman, it is claimed, built a
+steamboat (Fig. 15) which made a successful trip on the river Soane, in
+the year 1783, before a multitude of witnesses. This claim may or may
+not be just. It may be as the French say: the boat after the trial trip
+may have been taken to pieces, the model may have been lost and the
+French Revolution may have swallowed up those who witnessed the trip.
+
+[Illustration: FIG. 15.--THE MARQUIS OF JOUFFROY'S STEAMBOAT, 1783.]
+
+About the time the Frenchman is said to have been experimenting with his
+steamboat on the Soane similar experiments were being tried in many
+other places. In the latter part of the eighteenth century the idea of a
+steam-propelled boat seemed to be in the air. An English poet of the
+time was bold enough to prophesy:
+
+ Soon shall thy arm, Unconquered Steam, afar
+ Drag the slow barge and draw the rapid car,
+ Or on wide, waving wings, expanded bear
+ The flying chariot through the fields of air.
+
+For the most part the prophesy has been fulfilled, although the steam
+flying-machine is not yet an accomplished fact. Among those who helped
+to make good the words of the poet was James Rumsey, of Sheppardtown,
+Virginia. Rumsey in 1786 propelled, by means of steam, a boat on the
+Potomac River moving at the rate of five miles an hour. It is almost
+certain that this was the first boat ever drawn by steam. How did Rumsey
+drive his boat? A piston in a cylinder was worked by a steam-engine.
+When the piston was raised it brought water in and when it was pushed
+down it forced the water out behind and the reaction of the jet pushed
+the boat along. A remarkable revival of a very ancient idea! Just as
+Hero turned his globe by reaction, just as Newton pushed the first steam
+carriage along by reaction, so Rumsey pushed the first steamboat along
+by reaction.
+
+If you will look on a map of the United States and observe the vast
+network of waterways which come to the different parts of the country
+you will understand how important a subject steam navigation must have
+been to the people of America in the latter part of the eighteenth
+century. Here was a tract of land containing millions upon millions of
+fertile acres, but it lacked good roads, and without roads it could not
+be developed. It was, however, traversed by thousands of miles of
+excellent water-roads and it was plain that if steamboats could be put
+upon these rivers the gain would be incalculable. The most pressing need
+of the time, therefore, was a steamboat. No one saw this more clearly
+than John Fitch. This talented but eccentric man served his country in
+the Revolution, and after the war was over roamed hither and thither for
+several years as a soldier of fortune. About 1785 he went to
+Philadelphia with a plan for a steamboat. He organized a company, and
+secured enough money to enable him to carry out his plans. His boat was
+ready by August, 1787, and he made his trial trip in Philadelphia when
+the Constitutional Convention was in session. Many of the members of
+that distinguished body went down to the river to see how the new
+invention worked. It worked fairly well, but did not arouse much
+enthusiasm. Its speed was only three or four miles an hour and its
+movement was exceedingly awkward. It was pushed along by two sets of
+oars, one set entering into the water as the other came out. The steam
+rowboat of 1787 proved at least to be a failure, and was abandoned as
+worthless. Fitch afterward built another steamboat, but it also met with
+accident and came to naught. Heartbroken by his many failures the poor
+fellow at last ended his life with his own hand. He deserved a better
+fate, for his experiments taught the world a great deal about the
+steamboat.
+
+[Illustration: FIG. 16.--THE CHARLOTTE DUNDAS, 1802.]
+
+While Rumsey and Fitch were making their boats in America, European
+inventors were not idle. On the contrary they were so very active that
+they almost won the honor of making the first successful boat. One of
+these, William Symington, an Englishman, built a boat that may, with
+much justice, be called the first practical steamboat that was ever
+launched. This was the _Charlotte Dundas_ (Fig. 16) which made its trial
+trip on the Clyde and Firth Canal in 1802. On the _Charlotte_ was a
+_paddle-wheel_ instead of Fitch's two sets of paddles. The wheel was
+placed at the rear of the boat and was drawn by means of a crank which
+was turned by a rod attached to the piston-rod. Watt and his co-workers,
+a few years before, had shown how the steam-engine could be made to turn
+a wheel and Symington in the construction of his boat put this principle
+to good use. The _Charlotte_ did so well that the Duke of Bridgewater
+ordered eight more boats like her to be built for use on the canal.
+Symington was elated for he thought he had at last made a successful
+steamboat, that is, a steamboat that would give to its owner a profit;
+but he was doomed to disappointment for the owners of the canal refused
+to allow steamboats to be employed upon it, and worse than this the
+duke soon died and the inventor's financial support was gone. The
+_Charlotte_ was taken off the canal and laid in a creek where she fell
+to pieces. The really successful steamboat had not yet been built.
+
+It was to be built first where it was needed most, and that was in
+America. It was built by a man who kept his eyes on Rumsey and Fitch and
+Symington, and made the best of what he saw. As all the world knows,
+this was Robert Fulton. In August of 1807 Fulton's steamboat the
+_Clermont_ (Fig. 17) made a trip on the Hudson River from New York to
+Albany, a distance of 150 miles, in thirty-two hours, and returned in
+thirty hours. Fulton advertised for passengers, and his boat was soon
+crowded. "The _Clermont_," says an English writer, "was the steamboat
+that commenced and continued to run for practical purposes, and for the
+remuneration of her owners." Here was the boat that was wanted--one that
+was financially profitable.
+
+[Illustration: FIG. 17.--FULTON'S STEAMBOAT, CLERMONT.]
+
+[Illustration: FIG. 18.--THE BOAT OF STEVENS.]
+
+The paddle-wheels of the _Clermont_ were on the sides of the boat about
+midship. As the wheel turned, about half of it was in the water and
+about half was out. There were engineers, even in Fulton's day who did
+not believe the wheels ought to be on the sides of the boat. Look at
+waterfowl, they said, look at the graceful swan; its feet do not work at
+its sides, half under the water and half out. Every animal that swims
+propels itself from behind, and its propellers are entirely under the
+water. So, thought these engineers, the paddle-wheel of a boat should be
+placed behind, and should be entirely covered by the water. John
+Stevens, an engineer of Hoboken, New Jersey, in 1805 built a steamboat
+according to this notion (Fig. 18). A close inspection of the wheel of
+the boat would show that it is spiral- or screw-like in shape. Stevens'
+boat made a trial trip on the Hudson and worked well; but after Fulton's
+great success the little steamer with its spiral-shaped wheel in the
+rear was soon forgotten. The idea of a screw-propeller, however, was not
+lost. It was taken up by John Ericsson, a Swedish engineer, who, in
+1839, built, in an English shipyard for an American captain, the first
+screw-propeller that crossed the Atlantic--the _Robert F. Stockton_.
+This was the last step in the development of the boat. Since 1839 there
+has been marvelous progress in ship-building, but the progress has
+consisted in improving upon the invention of Ericsson rather than in
+making new discoveries. With the screw-propeller in its present form we
+may close our story of the boat. The homely log propelled by rude
+paddles has become the magnificent floating palace.

+THE CLOCK
+
+
+"Tic-tac! tic-tac! go the wheels of time. We cannot stop them; they will
+not stop themselves." Time passing is life passing and the measurement
+of time is the measurement of life itself. How important then that our
+chronometers, or time measures, be accurate and faithful! It is said
+that a slight error in a general's watch caused the overthrow of
+Napoleon at Waterloo and thus changed the history of the world. Because
+of its great importance the measurement of time has always been a
+subject of deep human interest and the story of the clock begins with
+the history of primeval man.
+
+The larger periods of time are measured by the motion of the heavenly
+bodies. The year and the four seasons are marked off by the motion of
+the earth in its long journey around the sun; the months and the weeks
+are told by the changing moon; sunrise and sunset announce the coming
+and the going of day. The year and the seasons and the day were measured
+for primeval man by the great clock in the heavens, but how were smaller
+periods of time to be measured? How was the passing of fractional parts
+of a day, an hour or a minute or a second to be noted? An egg was to be
+boiled; how could the cook tell when it had been in the water long
+enough? A man out hunting wished to get back to his family before dark:
+how was he to tell when it was time to start homeward?
+
+[Illustration: FIG. 1.--A PRIMITIVE SUN-DIAL.]
+
+Plainly, the measurement of small portions of time was a very practical
+problem from the beginning. The first attempt to solve the problem
+consisted in observing shadows cast by the sun. The changing shadow of
+the human form was doubtless the first clock. As the shadow grew shorter
+the observer knew that noon was approaching; when he could reach out one
+foot and step on the shadow of his head he knew it was time for dinner;
+when his shadow began to lengthen he knew that evening was coming on.
+Observations of this kind led to the _shadow clock_ or _sun-dial_ (Fig.
+1). You can make one for yourself. On a perfectly level surface exposed
+all day to the sun, place in an upright position (Fig. 1) a stick about
+three feet long, and trace on the surface the shadows as they appear at
+different times of the day. A little study will enable you to use the
+shadows for telling the time. Sun-dials have been used from the
+beginning of time and they have not yet passed out of use. They may
+still be seen in a few public places (Fig. 2), but they are retained
+rather as curiosities than as real timekeepers. For the sun-dial is not
+a good timekeeper for three reasons: (1) it will not tell the time at
+night; (2) it fails in the daytime when the sun is not shining; (3) it
+can never be used inside of a house.
+
+[Illustration: FIG. 2.--A MODERN SUN-DIAL.]
+
+The sun-dial can hardly be called an invention; it is rather an
+observation. There were, however, inventions for measuring time in the
+earliest period of man's history. Among the oldest of these was the
+fire-clock, which measured time by the burning away of a stick or a
+candle. The Pacific islanders still use a clock of this kind. "On the
+midrib of the long palm-leaf they skewer a number of the oily nuts of
+the candle-nut-tree and light the upper one." As the nuts burn off, one
+after another, they mark the passage of equal portions of time. Here is
+a clock that can be used at night as well as in the daytime, in the
+house as well as out of doors. Mr. Walter Hough tells us that Chinese
+messengers who have but a short period to sleep place a lighted piece of
+joss-stick between their toes when they go to bed. The burning stick
+serves both as a timepiece and as an alarm-clock.
+
+Fire-clocks of one kind or another have been used among primitive people
+in nearly all parts of the globe, and their use has continued far into
+civilized times. Alfred the Great (900 A. D.) is said to have measured
+time in the following way: "He procured as much wax as weighed
+seventy-two pennyweights, which he commanded to be made into six
+candles, each twelve inches in length with the divisions of inches
+distinctly marked upon it. These being lighted one after another,
+regularly burnt four hours each, at the rate of an inch for every twenty
+minutes. Thus the six candles lasted twenty-four hours."[19]
+
+We all remember Irving's account of time-measurement in early New York:
+"The first settlers did not regulate their time by hours, but pipes, in
+the same manner as they measure distance in Holland at this very time;
+an admirably exact measurement, as the pipe in the mouth of a true-born
+Dutchman is never liable to those accidents and irregularities that are
+continually putting our clocks out of order." This, of course, is not
+serious, yet it is an account of a kind of fire-clock that has been
+widely used. Even to-day the Koreans reckon time by the number of pipes
+smoked.
+
+If we could step on board a Malay proa we should see floating in a
+bucket of water a cocoanut shell having a small perforation through
+which the water by slow degrees finds its way into the interior. This
+orifice is so perforated that the shell will fill and sink in an hour,
+when the man on watch calls the time and sets it to float again. This
+sinking cocoanut shell, the first form of the water-clock, is the clock
+from which has been developed the timepiece of to-day. With it,
+therefore, the story of the clock really begins. In Northern India the
+cocoanut shell is replaced by a copper bowl (Fig. 3). At the moment the
+sinking occurs the attendant announces the hour by striking upon the
+bowl.
+
+[Illustration: FIG. 3.--AN EARLY FORM OF THE WATER-CLOCK.]
+
+The second step in the development of the water-clock was made in China
+several thousand years ago. In the earlier Chinese clock the water,
+instead of finding its way into the vessel from the outside, was placed
+inside and allowed to trickle out through a hole in the bottom and fall
+into a vessel below. In the lower vessel was a float which rose with the
+water. To the float was attached an indicator which pointed out the
+hours as the water rose. By this arrangement, when the upper vessel was
+full, the water, by reason of greater pressure, ran out faster at first
+than at any other time. The indicator, therefore, at first rose faster
+than it ought, and after a while did not rise as fast as it ought to.
+After centuries of experience with the two-vessel arrangement, a third
+vessel was brought upon the scene. This was placed above the upper
+vessel, which now became the middle vessel. As fast as water flowed from
+the middle vessel it was replaced by a stream flowing from the one above
+it. The depth of the water in the middle vessel did not change, and the
+water flowed into the lowest vessel at a uniform rate. Finally a fourth
+vessel was brought into use. The Chinese water-clock shown in (Fig. 4)
+has been running in the city of Canton for nearly six hundred years.
+Every afternoon at five, since 1321, the lowest jar has been emptied
+into the uppermost one and the clock thus wound up for another day.
+
+[Illustration: FIG. 4.--CHINESE WATER-CLOCK AT CANTON.]
+
+[Illustration: FIG. 5.--AN EARLY GREEK CLEPSYDRA.]
+
+To follow the further development of the water-clock we must pass from
+China to Greece. In their early history the Greeks had nothing better
+than the sun-dial with which to measure time. About the middle of the
+fifth century B. C. there arose at Athens a need for a better timepiece.
+In the public assembly the orators were consuming too much time, and in
+the courts of law the speeches of the lawyers were too long. It was a
+common thing for a lawyer to harangue his audience for seven or eight
+hours. To save the city from being talked to death a time-check of some
+kind became necessary. The sun-dial would not answer, for the sun did
+not always shine, even in sunny Greece; so the idea of the water-clock
+was borrowed. A certain amount of water was placed in an amphora (urn),
+in the bottom of which was a small hole through which the water might
+slowly flow (Fig. 5). When the amphora was empty the speaker had to stop
+talking. The Greeks called the water-clock a _clepsydra_, which means
+"the water steals away." The orator whose time was limited by a certain
+amount of water would keep his eye on the clepsydra, just as a speaker
+in our time keeps his eye on the clock, and if he were interrupted he
+would shout to the attendant, "You there, stop the water," or would say
+to the one who interrupted him, "Remember, sir, you are in my water."
+The story goes that upon one occasion the speaker stopped every now and
+then to take a drink; the orator's speech, it seems, was as dry as his
+throat, and a bystander cried out: "Drink out of the clepsydra, and
+then you will give pleasure both to yourself and to your audience."
+
+[Illustration: FIG. 6.--AN IMPROVED GREEK CLEPSYDRA.]
+
+At first the Greeks used a simple form of the clepsydra, but they
+gradually adopted the improvements made by the Chinese, and finally
+added others. The great Plato is said to have turned his attention to
+commonplace things long enough to invent a clepsydra that would announce
+the hour by playing the flute. However this may have been, there was in
+use in the Greek world, about 300 B. C., a clepsydra something like the
+one shown in Fig. 6. This begins to look something like a clock. As the
+water drops into the cylinder _E_ the float _F_ rises and turns _G_,
+which carries the hour hand around. Inside of the funnel _A_ is a cone
+_B_ which can be raised or lowered by the bar _D_. In this way the
+dropping of the water is regulated. Water runs to the funnel through
+_H_, and when the funnel is full the superfluous water runs off through
+the pipe _I_, and thus the depth of the water in the funnel remains the
+same and the pressure does not change. Notice that when the hand in this
+old clock has indicated twelve hours it begins to count over again, just
+as it does on our clocks to-day. How easily it would have been to have
+continued the numbers on to twenty-four, as they do in Italy, and on
+the railroads in parts of Canada, to-day.
+
+If we pass from Greece to Rome, our usual route when we are tracing a
+feature of our civilization, we find that the Romans were slow to
+introduce new methods of timekeeping. The first public sun-dial in Rome
+was constructed about 200 B. C., an event which the poet Plautus
+bewailed:
+
+ Confound the man who first found out
+ How to distinguish hours! Confound them, too
+ Who in this place set up a sun-dial
+ To cut and hack my days so wretchedly
+ Into small portions! When I was a boy
+ My stomach was my sun-dial, one more sure,
+ Truer, and more exact than any of them,
+ This dial told me when 'twas the proper time
+ To go to dinner.
+
+The water-clock was brought into Rome a little later than the sun-dial,
+and was used as a time-check upon speakers in the law courts, just as it
+had been in Athens. When the Romans first began to use the clepsydra it
+was already a very good clock. Whether it received any great
+improvements at their hands is not certain. Improvements must have been
+made somewhere, for early in the Middle Ages we find clepsydras in forms
+more highly developed than they were in ancient times. In the ninth
+century the Emperor Charlemagne received as gift from the King of Persia
+a most interesting timepiece which was worked by water. "The dial was
+composed of twelve small doors which represented the divisions of the
+hours; each door opened at the hour it was intended to represent, and
+out of it came the same number of little balls, which fell, one by one
+at equal distances of time, on a brass drum. It might be told by the eye
+what hour it was by the number of doors that were open; and by the ear
+by the number of balls that fell. When it was twelve o'clock, twelve
+horsemen in miniature issued forth at the same time, and, marching round
+the dial, shut all the doors." Less wonderful than the clock of the
+emperor, but more useful as an object of study, is the medieval
+clepsydra shown in Figure 7. This looks more than ever like the clock we
+are accustomed to see. It has weights as well as wheels. As the float
+_A_ rises with the water it allows the weight _C_ to descend and turns
+the spindle _B_ on the end of which is the hand which marks the hours.
+Notice carefully that this is partly a water-clock and partly a
+_weight_-clock. The weight in its descent turns the spindle; the water
+regulates the rate at which the weight may descend.
+
+[Illustration: FIG. 7.--A MEDIEVAL CLEPSYDRA.]
+
+[Illustration: FIG. 8.--DE VICK'S CLOCK. THE FIRST WEIGHT CLOCK.
+(1370.)]
+
+The water-clock just described led easily and directly to the
+weight-clock. Clockmakers in the Middle Ages for centuries tried with
+more or less success to make clocks that would run by means of weights.
+In 1370, Henry De Vick, a German, succeeded in solving the problem. De
+Vick was brought to Paris to make a clock for the tower of the king's
+palace, and he made one that has become famous. In a somewhat improved
+form it can still be seen in Paris in the Palais de Justice. Let us
+remove the face of this celebrated timepiece and take a look at its
+works (Fig. 8). It had a striking part, and a timekeeping part, each
+distinct from the other. The figure shows only the timekeeping part. The
+weight (A), of 500 pounds, is wound up by a crank (the key) at _P_. _O_
+is the hour-hand. If _A_ is allowed to descend, you can easily see how
+the whole system of wheels will be moved--and that very rapidly. But if
+something does not prevent, _A_ will descend faster and faster, the
+hour-hand will run faster and faster and the clock will run down at
+once. If the clock is to run at a uniform rate and for any length of
+time, the power of the weight must escape gradually. In the clepsydra
+(Fig. 1) the descent of the weight was controlled by the size of the
+stream of flowing water. De Vick invented a substitute for the stream of
+flowing water. Fasten your attention upon the workings of the
+saw-toothed wheel _II_ and the upright post _K_, which moves on the
+pivots _l_ and _k_, and you may learn what he did. Fixed to the upper
+part of the post _K_ is a beam or balance _LL_, at the ends of which are
+two small weights _m_ and _m_, and projecting from the post in different
+directions are two pallets or lips _i_ and _h_. Now, as the top of the
+wheel _II_ turns toward you, one of its teeth catches the pallet _i_ and
+turns the post _K_ a part of the way round _toward_ you. Just as the
+tooth _escapes_ from _i_ a tooth at the bottom of _II_ (moving from you)
+catches the pallet _h_ and checks the revolving post and turns it _from_
+you. Thus as _II_ turns, it gives a to-and-fro motion to the post _K_
+and, consequently, a to-and-fro motion to the balance _LL_. _II_ is
+called the _escapement_ because the power of the descending weight
+gradually _escapes_ from its teeth. In the clepsydra the trickling of
+_water_ regulated the descent of the weight; in De Vick's clock the
+trickling of _power_ or _force_ from the escapement regulated the
+descent of the weight. The invention of this escapement is the greatest
+event in the history of the clock. The king was much pleased with De
+Vick's invention. He gave the clockmaker three shillings a day, and
+allowed him to sleep in the clock tower; a scanty reward indeed for one
+who had done so much for the world, for De Vick's invention led rapidly
+to the excellent timepieces of to-day, to both our watches and our
+clocks. After the appearance of the weight-clock, the water-clock
+gradually fell into disuse, and all the ingenuity of the clockmaker was
+bestowed upon weights and wheels and escapements and balances. A century
+of experimenting resulted in a clock without a weight (Fig. 9). In this
+timekeeper you recognize the beginnings of the modern watch. The
+uncoiling of a spring drove the machinery. Instead of the balancing beam
+with its weights as in De Vick's clock, a _balance wheel_ is used. The
+escapement is the same as in the first weight-clock. The busy and
+delicately-hung little balance wheel in your watch is a growth from De
+Vick's clumsy balance beam. The spring-clock would run in any position.
+Because it could be carried about it led almost at once to the watch.
+Many places claim the distinction of having made the first watch, but it
+seems that the honor belongs to the city of Nürenburg. "Nürenburg eggs,"
+as the first portable clocks were called, were made as early as 1470.
+The first watches were large, uncouth affairs, resembling small table
+clocks but by the end of the sixteenth century small watches with works
+of brass and cases of gold or silver were manufactured (Fig. 10).
+
+[Illustration: FIG. 9.--A CLOCK WITHOUT WEIGHTS.]
+
+[Illustration: FIG. 10.--A WATCH OF THE 16TH CENTURY.]
+
+[Illustration: FIG. 11.--GALILEO'S PENDULUM. (1650.)]
+
+The last important step in the development of the clock was taken when
+the _pendulum_ was brought into use. The history of the pendulum will
+always include a story told by Galileo. This great astronomer, the story
+runs, while worshiping in the cathedral at Pisa one day, found the
+service dull, and began to observe the swinging of the lamps which were
+suspended from the ceiling. Using his pulse as a timekeeper he learned
+that where the chains were of the same length the lamp swayed to and fro
+in equal length of time, whether they traveled through a short space or
+a long space. This observation set the philosopher to experimenting with
+pendulums of different lengths. Among the many things he learned one of
+the most important was this: a pendulum thirty-nine inches in length
+will make one vibration in just one second of time. Now, if the pendulum
+could only be kept swinging and its vibrations counted it would serve
+as a clock. Galileo, of course, saw this, and he caused to be made a
+machine for keeping the pendulum in motion (Fig. 11), but he did not
+make a clock; he did not connect his pendulum with the works of a clock.
+This, however, was done about the middle of the seventeenth century,
+although it is somewhat difficult to tell who was the first to do it.
+The honor is claimed by an Englishman, a Frenchman, and a Dutchman. The
+truth is, clockmakers throughout Europe were trying at the same time to
+make the best of the discoveries of Galileo, and several of them about
+the same time constructed clocks with pendulums. The one who seems to
+have succeeded first was Christian Huygens, a Dutch astronomer, who, in
+1656, constructed a clock, the motions of which were regulated by the
+swinging of a pendulum (Fig. 12). The weight was attached to a cord
+passing over a pulley and gave motion to all the wheels, as in De Vick's
+clock. Like De Vick's clock also Huygens's clock had its escapement
+wheel acting upon two pallets. In the Dutchman's clock, however, the
+escapement, instead of turning a balance beam to and fro, acted upon the
+pendulum, giving it enough motion to keep it from stopping.
+
+[Illustration: FIG. 12.--THE FIRST PENDULUM CLOCK. (1656.)]
+
+We need not carry our story further than the invention of Huygens.
+Timepieces are cheaper and better made and more accurate than they were
+two hundred years ago, but no really important discovery has been made
+since the pendulum was introduced.

+
+THE BOOK
+
+
+What is a book? It is an invention by means of which _thought_ is
+recorded, and carried about in the world, and handed down from one age
+to another. Almost as soon as men began to think they began to make
+books and they will probably continue to make them as long as they
+continue to think. The story of the Book, therefore, takes us back to
+the very beginning of human existence.
+
+At first thought was recorded and preserved by _tradition_. An account
+of a nation's deeds, its laws, the precepts of its religion were
+stamped, printed, on the memory of persons specially trained to memorize
+these things and hand them down by word of mouth from generation to
+generation (Fig. 1). These persons were usually priests, who underwent
+long years of daily and hourly training in memorizing what was to be
+handed down. The Sanskrit Vedas, the sacred scripture of the Hindoos,
+were for many centuries transmitted by tradition, and it is said it took
+forty years to memorize them. It is a wonder it did not take longer, for
+the Vedas make a volume as large as our Bible. It is believed that
+primitive people everywhere first adopted the method of tradition to
+record and preserve the thought which they did not wish to perish. We
+may say, then, that the first book was written on the tablet of the
+human memory.
+
+[Illustration: FIG. 1.--TRADITION.
+
+A Mural Decoration in the Library of Congress.]
+
+The first step in the growth of the book was taken when _memory aids_
+were invented. Sometimes we tie a knot in a handkerchief to help us to
+remember something. Now, it was just by tying knots that primitive man
+first lent assistance to the memory. The first material book was
+doubtless a series of _knots_ well represented by the _quipu_ (Fig. 2)
+of the ancient Peruvians. This curious-looking book was written (tied)
+by one known as the officer of the knots. It contains an account of the
+strength of the Peruvian army, although it is confessed that its exact
+meaning cannot be made out. It was not intended to be read by any one
+who was not a keeper of the knots. Books made of knots were used by
+nearly all the ancient peoples of South America and by some of those of
+Asia. Akin to the knotted cord is the _notched stick_, which is still
+used in Australia by the savages to assist the memory of one who has a
+message to carry. Figure 3 shows a variety of such message-sticks. The
+lowest one--a crooked branch of a tree--contains an invitation to a
+dancing party. The notches are read by the messenger. The notched stick
+as an aid to memory is not confined to savage races. Many a highly
+civilized baker has kept his accounts by making notches in sticks and so
+has many a modern dairyman, as he has delivered milk from door to door.
+
+[Illustration: FIG. 2.--THE QUIPU OF THE PERUVIANS.]
+
+[Illustration: FIG. 3.--MESSAGE-STICKS.]
+
+Memory aids were followed by _picture-writing_. To express thought by
+means of pictures is an instinct shared alike by the lowest savage and
+the most enlightened people. All over the earth we find examples of
+early picture-writing. A beloved chief had died, a fierce battle had
+been fought, an exciting chase had occurred: promptly the event was
+pictured on a stone or on the skin of some animal. Pages might be filled
+with illustrations of these primitive picture-books, but we must be
+content with a single specimen (Fig. 4). This was found painted on a
+rock in California: "_We selected this as a camping place, but we have
+found nothing_," say the human figures _f_, _g_, _h_, _i_. The upturned
+palms say plainly, "nothing, nothing." "_One of our comrades_ (_d_) _has
+died of starvation_," say the three lank figures at _c_ pointing to their
+own lean bodies. "_We deeply mourn his loss_," says the sorrow-stricken
+_a_. "_We have gone northward_," says _j_, his distinguished arm
+extended to the north.
+
+[Illustration: FIG. 4.--PICTURE WRITING.]
+
+Practice in picture-making was bound to lead to shorter methods of
+expressing ideas. It was soon found that reduced pictures, or
+_picture-signs_, would suffice to express ideas. Thus, if the idea of
+sorrow was to be expressed it was not necessary to draw an elaborate
+picture of a sorrowful looking man like _a_ in Figure 4; a weeping eye
+would express the idea just as well. Instead of numerous figures (_e_,
+_f_, _g_, _h_, _i_) weeping and saying, "nothing here," a single pair of
+empty palms would say the same thing just as clearly. In this way a
+pair of clasped hands came to mean "friendship"; two trees meant "a
+forest"; a calf running toward water meant "thirst." These
+picture-signs, of course, assumed the form in which they could be most
+easily and rapidly drawn. The weeping eye became [symbol: eye]; the pair
+of extended palms [symbol: palms]; the forest [symbol: trees]; thirst
+[symbol: dog walking on water]. A simple picture of this kind became a
+fixed conventional sign for certain ideas; it was always drawn in the
+same way and it always stood for the same idea.
+
+Picture-signs (ideographs) followed picture-writing in almost every
+country where the people were progressive. China was writing its books
+with picture-signs many thousands of years ago, and it is writing them
+in the same clumsy way still. Even in highly civilized countries
+picture-signs have not been entirely abandoned. Examine the advertising
+page of a newspaper or observe the business signs on the street and you
+will find picture-signs--pictures that are always made in the same way
+and that always stand for the same thing.
+
+Each of the great nations of antiquity had its own peculiar system of
+writing, but the system that should interest us most is that of ancient
+Egypt, for it is to ancient Egypt that you must look for the origin of
+the book that is in your hands. The book in Egypt passed through the
+stages of tradition, memory aids, picture-writing and picture-signs
+(ideographs); then it passed into the _alphabetic_ stage. Since the
+alphabet is certainly the most wonderful and perhaps the most useful of
+all inventions, and since it is an Egyptian invention, it is well worth
+your while to learn how the Egyptian picture-signs--hieroglyphics they
+are called--grew into letters, but if you wish to understand the change
+you will have to give the subject very close attention.
+
+Well, here was the Egyptian system of picture-signs consisting of
+several thousand pictures of birds, beasts, reptiles, insects, trees,
+flowers, and objects of almost every description. Now suppose you were
+employed in writing _English_ by means of several thousand picture-signs
+and in the course of an hour would have to write the words _man_age,
+_man_sion, _man_tle, _man_date, might it not occur to you that it would
+be a good thing if that sound _man_ could be represented by the
+picture-sign for man ([symbol: man])? And if you had to write _trea_cle,
+_trea_son, _trea_ty, might you not feel like beginning these words with
+a tree ([symbol: tree])? At some time in the remote past Egyptian
+scribes--priests they usually were--noticing that syllables identical in
+sound were constantly recurring in the different words, began to
+represent these _syllable-sounds_ that occurred most frequently by
+_picture-signs_.[20] The picture-sign substituted for a syllable-sound
+was placed in the word not because it stood for an _idea_, but because
+it stood for a _sound_, just as in the case supposed above you would use
+the [symbol: man] or the [symbol: tree] not because it represented a
+thought, but because it had a certain sound. So certain Egyptian
+picture-signs began to be used to represent the sound of certain
+syllables. The picture-signs thus chosen were called _phonograms_.
+
+The phonogram led to the alphabet. The scribes in seeking a way to
+shorten their work found that the syllable itself could be broken up
+into separate sounds. For example, when they came to the syllable whose
+sound is spelled by our three letters _pad_, they found that it had
+three distinct sounds, namely: (1) one a lip sound which could be
+represented by the first sound of the picture-sign [symbol: door] (a
+door); (2) one an open-throat or vowel sound which could be represented
+by the first sound of the picture-sign [symbol: eagle] (an eagle); (3)
+one a dental sound which could be represented by the first sound in the
+picture-sign [symbol: hand] (a hand). So the scribes wrote the syllable
+(p-a-d) with the three characters [symbol: door] [symbol: eagle]
+[symbol: hand]. And so with all the other sounds in the Egyptian
+language; each was represented by one of the picture-signs already used.
+Since there were only about twenty-five distinct elementary sounds in
+the Egyptian language, twenty-five picture-signs were sufficient to
+represent any sound or any word in the language. These twenty-five
+picture-sounds were the letters of the Egyptian alphabet. Twenty-five
+characters instead of thousands! Now the Egyptian youth could learn to
+read in three or four years, whereas under the old system it took
+fifteen or twenty years, just as it takes fifteen or twenty years for
+the Chinese youth to learn to read well.
+
+Now that its origin has been explained, the story of the alphabet may be
+rapidly told. Indeed, its whole history can be learned from Figure 5. In
+column (a) are the three Egyptian picture-signs referred to above.
+Column (b) shows how the rapid writing of the priests reduced the old
+hieroglyphics to script; [symbol: door] became [symbol: 3 c's]; [symbol:
+eagle] became [symbol: odd a] and [symbol: hand] became [symbol:
+squiggle]. The Phoenicians, who were great travelers, visited Egypt at a
+very early date and borrowed not only the idea of the alphabet, but also
+the forms of the Egyptian letters, as column _c_ shows. Column _d_
+confirms the words of Herodotus, who tells us that the Greeks borrowed
+their alphabet from the Phoenicians. Column _e_ shows that the Greeks
+handed the alphabet on to the Romans, who handed it on to us. Thus the
+three letters p, a, d come straight from the Egyptians and were
+originally a _door_, an _eagle_, and a _hand_, respectively. As it is
+with these three letters, so it is with nearly all the letters of our
+alphabet. If the letters on the page before you could be suddenly
+changed to their original form, you would behold a motley collection of
+birds, serpents, animals, tools, and articles of household use.
+
+[Illustration: FIG. 5.--SHOWING THE DEVELOPMENT OF THE THREE LETTERS, P,
+A, AND D.]
+
+[Illustration: FIG. 6.--AN ANCIENT VOLUME.]
+
+We must look to Egypt for the origin of the material form of our book as
+well as for the origin of our alphabetical characters. Before history
+had dawned the Egyptians had covered over with their writing nearly all
+the available surface on their pyramids and in their temples. At a time
+too far back for a date necessity seems to have compelled them to seek
+a substitute for stone. This they found in the _papyrus_ plant, which
+grew in great luxuriance in the valley of the Nile. They placed side by
+side strips of the pith of the papyrus, and across these at right angles
+they placed another layer of strips. The two layers were then glued
+together and pressed until a smooth surface was formed. This made one
+sheet. To make a book a number of sheets were fastened together end to
+end. When in book form the papyrus was wound around a stick and kept in
+the form of a roll, a _volume_ (Fig. 6). The roll was usually eight or
+ten inches wide, but its length might be upward of a hundred feet. This
+papyrus roll was the parent of our modern paper book, as the word
+papyrus is the original of our word paper. The pen used in writing upon
+papyrus was a split reed (_calamus_), and the ink a mixture of soot and
+gum.
+
+[Illustration: FIG. 7.--THE OLDEST BOOK IN THE WORLD. WRITTEN NEARLY
+5,000 YEARS AGO.]
+
+The most ancient volume in the world is an Egyptian papyrus (Fig. 7) now
+in the National Library of France. It was written nearly 5,000 years ago
+by an aged sage and contains precepts of right living. In this oldest of
+volumes we find this priceless gem:
+
+"If thou art become great, if after being in poverty thou hast amassed
+riches and art become the first in the city, if thou art known for thy
+wealth and art become a great lord, let not thy heart become proud, for
+it is God who is the author of them for thee."
+
+In Assyria and in other ancient countries of Central Asia letters were
+engraved on cylinders and these were rolled upon slabs of soft clay,
+making an impression of the raised letters, just as we make an
+impression with the seal of a ring. In the ruins of the cities of
+Assyria these old clay books may be found by the cart-load. The Assyrian
+cylinder was really the first printing press. In ancient Greece and Rome
+wooden tablets within which was spread a thin layer of wax were used as
+a writing surface in schools and in the business world. The writing on
+the wax was done with a sharp-pointed instrument of bone or iron called
+the _stylus_. But next to papyrus the most important writing material of
+antiquity was _parchment_, or the prepared skin of young calves and
+kids. The invention of parchment is said to have been due to the
+literary ambitions of two kings, the king of Persia and the king of
+Egypt. The king of Pergamus (250 B.C.) wishing to have the finest and
+largest library in the world was consuming enormous quantities of
+papyrus. The king of Egypt, who also wished to have the finest library
+in the world, in order to cripple the plans of his literary rival,
+issued a command forbidding the exportation of papyrus from Egypt. The
+king of Pergamus, being unable to get papyrus except from Egypt, caused
+the skins of sheep to be prepared, and on these skins books for his
+library continued to be written. The prepared skins received the name of
+_pergamena_, because they were made in Pergamus, and from pergamena we
+get the word parchment. This is the story that has come down to us to
+explain the origin of parchment, but it cannot be accepted as wholly
+true. We know very well that the Old Testament was written in gold on a
+roll of skins long before there was a king of Pergamus. Indeed, writing
+was done on skins as far back as the picture-writing period.
+
+After the invention of the alphabet and of paper (papyrus) books
+multiplied as never before. "Of making many books there is no end,"
+exclaimed Solomon a thousand years before the Christian era. Greece in
+her early day was slow to make books, but after she learned from the
+Phoenicians (800 B.C.) how to use an alphabet she made up for lost time.
+In 600 B.C. there was a public library at Athens, and 200 years later
+the Greeks had written more good books than all the other countries in
+the world combined.
+
+But the most productive of ancient book-makers were the Romans. In Rome
+publishing houses were flourishing in the time of Cicero (50 B.C.).
+Atticus, one of Cicero's best friends, was a publisher. Let us see how a
+book was made in his establishment. Of course, there were no
+type-setters or printing-presses. Every book was a manuscript; every
+word of every copy had to be written with a pen. The writing was
+sometimes done by slaves trained to write neatly and rapidly. We may
+imagine 50 or 100 slaves sitting at desks in a room writing to the
+dictation of the reader. Now if Atticus had ten readers each of whom
+dictated to 100 slaves it took only two or three days for the
+publication of 1,000 copies of one of his friend Cicero's books. Of
+course every copy would not be perfect. The slave would sometimes make
+blunders and write what the reader did not dictate. But books in our own
+time are not free of errors. An English poet recently wrote:
+
+ "Like dew-drops upon fresh blown roses."
+
+In print the first letter of the last word in the line appeared as _n_
+instead of _r_. This mistake disfigured thousands of copies. In the
+Roman publishing house such a blunder marred only one copy.
+
+You can readily see that by methods just described books could be made
+in great numbers. And so they were. Slaves were cheap and numerous and
+the cost of publication was small. It is estimated that a good sized
+volume in Nero's time (50 A.D.) would sell for a shilling. Books were
+cheaper in those days than they had ever been before and almost as cheap
+as they are to-day, perhaps. The Roman world became satiated with
+reading matter. The poet Martial exclaimed, "Every one has me in his
+pocket, every one has me in his hand." Books became a drug on the market
+and could be sold only to grocers for "wrapping up pastry and spices."
+
+[Illustration: FIG. 8.--BOOK-MAKING IN THE MIDDLE AGES.]
+
+But a time was to come when books would not be so plentiful and cheap.
+With the overthrow of Rome (476 A.D.) culture received a blow from which
+it did not recover for a thousand years. The barbarian invaders of
+Southern Europe destroyed all the books they could find and caused the
+writers of books to flee within the walls of the churches. Throughout
+the Middle Ages nearly all the writing in Europe was done in the
+religious houses of monks (Fig. 8), and nearly all the books written
+were of a religious nature. The monks worked with the greatest patience
+and care upon their manuscripts. They often wrote on vellum (calf-skin
+parchment) and illuminated the page with beautiful colors and adorned it
+with artistic figures.
+
+The manuscript volumes of the dark ages were beautiful and magnificent,
+but their cost was so great that only the most wealthy could buy. A
+Bible would sometimes cost thousands of dollars. Along in the 14th and
+15th centuries Europe began to thirst for knowledge and there arose a
+demand for cheap books. How could the demand be met? There were now no
+hordes of intelligent slaves who could be put to work with their pens,
+and without slave labor the cost of the written book could not be
+greatly reduced. Invention, as always, came to the rescue and gave the
+world what it wanted.
+
+In the first place, writing material was made cheaper by the invention
+of paper-making. The wasp in making its nest had given a hint for
+paper-making, but man was extremely slow to take the hint. The Chinese
+had done something in the way of making paper from the bark of trees as
+early as the first century, but it was not until the middle of the 13th
+century that paper began to be manufactured in Europe from hemp, rags,
+linen, and cotton.
+
+[Illustration: FIG. 9.]
+
+In the second place, _printing_ was invented. On a strip of transparent
+paper write the word _post_. Now turn the strip over from right to left
+and trace the letters on the smooth surface of a block of wood. Remove
+the paper and you will have the result shown in Figure 9. With a sharp
+knife cut out the wood from around the letters. Ink the raised letters
+and press upon them a piece of paper. You have printed the word "post"
+in precisely the way the first books were printed. In the 13th century
+fancy designs were engraved on wood and by the aid of ink the figures
+were stamped on silk and linen. In the 14th century playing cards and
+books were printed on engraved blocks in the manner the word "post" was
+printed above. (Fig. 10.) The block-book was the first step in the art
+of printing.
+
+[Illustration: FIG. 10.--A BLOCK PRINT CONTAINING THE ALPHABET USED BY
+CHILDREN WHEN LEARNING TO READ.]
+
+The block-book decreased the cost of a book, for when a page was once
+engraved as many impressions could be taken as were wanted, yet it did
+not meet the necessities of the time. In the middle of the 15th century
+the desire for reading began to resemble a frenzy and the books that
+could be got hold of "were as insufficient to slake the thirsty craving
+for religious and material knowledge as a few rain drops to quench the
+burning thirst of the traveler in the desert who seeks for long,
+deep-draughts at copious springs of living water." To meet the demand of
+the time book-makers everywhere were trying to improve on the
+block-making process and by the end of the century the book as we have
+it to-day was being made throughout all Europe.
+
+In what did the improvement consist? First let us call to mind what the
+book-maker in the early part of the 15th century had to begin with; he
+had paper, he had printing-ink, he had skill in engraving whole pages
+for block-books, and he had a rude kind of printing-press. The
+improvement consisted in this: Instead of engraving a whole page on a
+block, single letters were engraved on little blocks called types, and
+when a word or a line or a page was to be printed these types were set
+in the position desired; in other words, the improvement consisted in
+the invention of _moveable types_. The types were first made of wood and
+afterward of metal.
+
+[Illustration: FIG. 11.--AN EARLY PRINTING PRESS.]
+
+The great advantage of the moveable types over the block-book is easily
+seen. A block containing, say, the word "post" is useless except for
+printing the word _post_; but divide it into four blocks, each
+containing a letter: now you can print _post_, _spot_, _tops_, _stop_,
+_top_, _sop_, _sot_, _pot_, _so_, _to_ and so forth.
+
+The exact date of the invention of moveable types cannot be determined.
+We can only say that they were first used between 1450 and 1460. Nor can
+we tell who invented them. The Dutch claim that Lawrence Koster of
+Harlem (Holland) made some moveable types as early as 1430, and that
+John Faust, an employee, stole them and carried them to Mayence
+(Germany), where John Gutenberg learned the secret of printing with
+them. The Germans claim that Gutenberg was the real inventor. Much can
+be said in behalf of both claims. What we really know is that the
+earliest complete book printed on moveable types was a Bible which came
+from the press of John Gutenberg in 1455.
+
+Since 1450 there has been no discovery that has changed the character of
+the printed volume. There have been wonderful improvements in the
+processes of making and setting type, and printing-presses (Fig. 11)
+have become marvels of mechanical skill, but the book of to-day is
+essentially like the book of four hundred years ago. The tablet of the
+memory, the knotted cord and notched stick, the uncanny picture-writing,
+the clumsy picture-sign, the alphabet, the manuscript volume, the
+printed block-book and the volume before you bring to an end the story
+of the book.

+
+THE MESSAGE
+
+
+Men had not been living together long in a state of society before they
+found it necessary to communicate with their fellow-men at a distance
+and in order to do this the _message_ was invented. We have seen (p.
+205) that among certain tribes of savages notched sticks bearing
+messages were sent from one tribe to another. Among the ancient
+Peruvians the message took the form of the curious looking quipu. After
+the alphabet had been invented and papyrus had come into use as a
+writing material, the message took the form of a written document and
+resembled somewhat the modern _letter_.
+
+[Illustration: FIG. 1.--A LETTER CARRIER OF ANCIENT EGYPT.]
+
+The ancient Egyptians, as we would expect, were the first to make use of
+the letter in the sending of messages (Fig. 1). The ancient Hebrews were
+also familiar with the letter as a means of communication. We read in
+the book of Chronicles how the post went with the letters of the king
+and his princes throughout all Israel. The word _post_, as used here and
+elsewhere in the Bible, signifies a runner, that is, one specially
+trained to deliver letters or despatches speedily by running. Thus
+Jeremiah predicted that after the fall of Babylon "one post shall run to
+meet another and one messenger to meet another to show the King that his
+city is taken." Although we frequently read of the post in Biblical
+times we are nowhere told that the ordinary people enjoyed the
+privileges of the post. In olden times it was only kings and princes and
+persons of high degree that sent and received letters.
+
+[Illustration: FIG. 2.--AN EGYPTIAN MAIL CART.]
+
+In nearly all the countries of antiquity there was an organized postal
+system which was under the control of the government and which carried
+only government messages. In Egypt there were postal chariots (Fig. 2)
+of wonderful lightness designed especially for carrying the letters of
+the king at the greatest possible speed. In ancient Judea messengers
+must have traveled very fast, for Job, in his old age, says: "Now my
+days are swifter than the post, they flee away." In ancient Persia the
+postal system awakened the admiration of Herodotus. "Nothing mortal,"
+says this old Greek historian, "travels so fast as these Persian
+messengers. The entire plan is a Persian invention and this is the
+method of it. Along the whole line of road there are men stationed with
+horses, the number of stations being equal to the number of days which
+the journey takes, allowing a man and a horse to each day, and these men
+will not be hindered from accomplishing at their best speed the distance
+they will have to go either by snow, or rain, or heat, or by the
+darkness of night. The first rider delivers the message to the second
+and the second to the third, and so it is borne from hand to hand along
+the whole line."
+
+[Illustration: FIG. 3.--A LETTER CARRIER OF ANCIENT GREECE.]
+
+The postal system which Herodotus found in Persia was better than the
+system which existed in his own country for the reason that the Greeks
+relied upon human messengers rather than upon horses to carry their
+messages. Young Greeks were specially trained (Fig. 3) as runners for
+the postal service and Greek history contains accounts of the marvelous
+endurance and swiftness of those employed to carry messages. After the
+defeat of the Persians by the Greeks at Marathon (490 B. C.) a runner
+carried the news southward and did not pause for rest until he reached
+Athens when he shouted the word "Victory!" and expired, being overcome
+by fatigue. Another Greek, Phillipides by name, was despatched from
+Athens to Sparta to ask the Spartans for aid in the war which the
+Athenians were carrying on against Persia, and the distance between the
+two cities--about 140 miles--was accomplished by the runner in less than
+two days.
+
+[Illustration: FIG. 4.--A LETTER CARRIER OF ANCIENT ROME.]
+
+But the best postal system of ancient times was the one which was
+organized by the Romans. As one country after another was brought under
+the dominion of Rome it became more and more necessary for the Roman
+government to keep in close touch with all the parts of the vast empire.
+Accordingly, by the time of Augustus (14 A.D.), there was established
+throughout the Roman world a fully organized and well-equipped system of
+posts. Along the magnificent roads which led out from Rome there were
+built at regular distances stations, or post-houses, where horses and
+riders were stationed for the purpose of receiving the messages of the
+government and hurrying them along to the place of their destination.
+The stations were only five or six miles apart and each station was
+provided with a large number of horses and riders. By the frequent
+changes of horses a letter could be hurried along with considerable
+speed (Fig. 4). "By the help of the relays," says Gibbon, "it was easy
+to travel a hundred miles in a day."
+
+When Rome fell (476 A.D.) before the attacks of barbarous tribes her
+excellent postal system fell with her and many centuries passed before
+messages could again be regularly and quickly despatched between widely
+separated points. Charles the Great, the emperor of the Franks,
+established (800 A.D.) a postal system in his empire but the service did
+not long survive the great ruler. In the 13th century the merchants of
+the Hanse towns of Northern Germany could communicate with each other
+somewhat regularly by letter, but the ordinary people of these towns did
+not enjoy the privileges of a postal service. In the Middle Ages, as in
+the ancient times, the public post was established solely for the
+benefit of the government. Private messages had to be sent as best they
+could be by private messengers and at private expense. As late as the
+reign of Henry VIII (1509-1547) the only regular post route in England
+was one which was established for the exclusive use of the king.
+
+But the time was soon to come when ordinary citizens as well as officers
+of state were to share in the benefits of a postal system. In 1635
+Charles I of England gave orders that a post should run night and day
+between Edinburgh and London and that postmen should take with them all
+such letters as might be directed to towns on or near the road which
+connected the two cities. The rate of postage[21] was fixed at two
+pence for a single letter when the distance was under sixty miles; four
+pence when the distance was between 60 and 140 miles; six pence for any
+longer distance in England; and eight pence from London to any place in
+Scotland. It was ordered that only messengers of the king should be
+allowed to carry letters for profit unless to places to which the king's
+post did not go. Here was the beginning of the modern postal system and
+the modern post-office. Henceforth the post was to carry not only the
+king's messages, but the messages of all people who would pay the
+required postage.
+
+The example set by England in throwing the post open to the public was
+followed by other nations, and before a hundred years had passed nearly
+all the civilized countries of the world were enjoying the privilege and
+blessings of a well-organized postal system. It is true that the post
+for a long time moved very slowly--a hundred miles a day was regarded as
+a flying rate--and postage for a long time was very high, but the
+service grew constantly better and by the close of the nineteenth
+century trains were dashing along with the mails at the rate of a
+thousand miles a day and postage within a country had been reduced to
+two cents,[22] while for a nickel a letter could be sent to the most
+distant parts of the globe.
+
+Thus far we have traced the history of only one kind of message, the
+kind that has the form of a written document and that is conveyed by a
+human carrier over land and water from one place to another. But there
+is a kind of message which is not borne along by human hands and which
+does not travel on land or water. This is the _telegraph_,[23] the
+message which darts through space and is delivered at a distant point
+almost at the very instant at which it is sent.
+
+The first telegraph was an aerial message and consisted of a signal made
+by a flash of light. From the earliest times men have used fire signals
+as a means of sending messages to distant points. When the city of Troy
+in Asia Minor was captured by the Greeks (about 1100 B.C.) torches
+flashing their light from one mountain top to another quickly carried
+the news to the far-off cities of Greece. The ancient Greeks gave a
+great deal of attention to the art of signaling by fire and they
+invented several very ingenious systems of aerial telegraphy. The most
+interesting of these systems is one invented and described by the Greek
+historian Polybius, who flourished about 150 B.C. When signaling with
+fire Polybius arranged for using two groups of torches with five torches
+in each group, and for the purpose of understanding the signals he
+divided the letters of the alphabet into five groups of five letters
+each.[24] The torches were raised according to a plan that made it
+possible to flash a signal that would indicate any letter of the
+alphabet that might be desired. Thus if the desired letter was the third
+one of the first group--that is, the letter _k_--one torch would show
+which group was meant and three torches would show which letter was
+meant (Fig. 5). In theory this system was perfect, for it provided for
+sending any kind of message whatever. But in practice it had little
+value, for it required so many torches and signals that an entire night
+was consumed in spelling out a few words.
+
+[Illustration: FIG. 5.--TELEGRAPHING BY MEANS OF FIRE, 150 B. C.]
+
+Although the elaborate system of aerial telegraph proposed by Polybius
+was not generally adopted, nevertheless for centuries, both in ancient
+times and during the middle ages, the fire signal was everywhere used
+for the quick despatch of important news. In the seventeenth century
+inventors began to devise new systems of aerial telegraphy. In 1663, the
+Marquis of Worcester, who was always busy with some great invention (p.
+178), announced to the world that he had discovered a plan by which one
+could talk with another as far as the eye could distinguish between
+black and white, and that this conversation could be carried on by night
+as well as by day, even though the night were as dark and as black as
+pitch. But the telegraph of the Marquis was like many of his other
+inventions--it was chiefly on paper. In 1864, Dr. Robert Hooke of
+England invented a method by which aerial messages could be sent a
+distance of thirty or forty miles. His plan was to erect on hill tops a
+series of high poles connected above by cross-pieces and by means of
+pulleys suspend from the cross-pieces the letters of the alphabet which
+would spell out the message (Fig. 6). In order to read the letters at
+such great distances the eye was assisted by the telescope, an
+instrument which had recently been invented.
+
+[Illustration: FIG. 6.--HOOKE'S AERIAL TELEGRAPH, 1684.]
+
+[Illustration: FIG. 7.--CHAPPE'S AERIAL TELEGRAPH, 1793.]
+
+But the greatest improvement in aerial telegraphy was made during the
+French Revolution by Claude Chappe, a Frenchman living in Paris. In
+1793, Chappe erected on the roof of the palace of the Louvre a post at
+the top of which was a cross-beam which moved on a pivot about the
+center like a scale beam (Fig. 7). The cross-beam could be moved
+horizontally, vertically or at almost any angle by means of cords.
+Chappe invented a number of positions for these arms and each position
+stood for a certain letter of the alphabet. Machines of this kind were
+erected on towers at places from nine to twelve miles apart and soon
+Chappe was sending messages from Paris to the city of Lille, 130 miles
+away. The messages were sent with great rapidity, for they passed from
+one tower to another with the velocity of light--about 185,000 miles a
+second--and it was possible for the operator to spell out about 100
+words in an hour. And Chappe's messages could be sent at any time, day
+or night, for the arms of the machine were furnished with Argand lamps
+for night work.
+
+Chappe's invention was the greatest which had thus far been made in the
+history of the message. The new system of telegraphy proved to be
+entirely successful and practical and it was not long before machines
+similar to those invented by Chappe were in use in England and other
+countries. In 1828, an English writer had the following words of praise
+for aerial telegraphy: "Telegraphs have now been brought to so great a
+degree of perfection that they carry information so speedily and
+distinctly and are so much simplified that they can be constructed and
+maintained at little expense. The advantages, too, which result from
+their use are almost inconceivable. Not to speak of the speed with which
+information is communicated and orders given in time of war, by means of
+these aerial signals the whole kingdom could be prepared in an instant
+to oppose an invading enemy."
+
+[Illustration: FIG. 8.--STURGEON ELECTRO-MAGNET, 1825.]
+
+But the aerial telegraph was soon to have a most dangerous rival. This
+rival was _the electric telegraph_. Many years before the invention of
+Chappe men had been experimenting with electricity with a view of
+sending messages by means of an electric current. These experiments
+began in 1728 when an Englishman named Gray caused electricity to
+produce motion in light bodies located at a distance of more than 600
+feet. In 1748, the great Benjamin Franklin, who conducted so many
+wonderful experiments in electricity, sent an electric current through a
+wire which was stretched across the Schuylkill River and set fire to
+some alcohol which was at the opposite end of the wire. We may regard
+the flash of alcohol as a telegraph, for it could have been used as a
+signal. In 1819, Professor Oersted of Copenhagen brought a magnetic
+needle close to a body through which an electric current was passing and
+he observed that the needle had a tendency to place itself at right
+angles to the electrified body. In 1825, William Sturgeon of England
+coiled a copper wire around a bar of soft iron and found that when a
+current of electricity was sent through the wire the bar of iron became
+a temporary magnet; that is, the bar of iron attracted a needle when the
+current was passing through the wire and ceased to attract it when the
+current was broken (Fig. 8). These discoveries of Oersted and Sturgeon
+led to the invention known as the _electro-magnet_ and the
+electro-magnet led rapidly to the invention of the electric telegraph,
+for by means of the electro-magnet a signal can be sent to a distance
+as far as a current of electricity can be sent along a wire. In 1831,
+Professor Joseph Henry, one of America's most distinguished scientists,
+discovered a method by which an electric current could be sent along a
+wire for a very great distance. The next year Henry constructed and
+operated an apparatus which was essentially an electric telegraph (Fig.
+9). "I arranged," he said, "around one of the upper rooms of the Albany
+Academy a wire of more than a mile in length through which I was enabled
+to make signals by sounding a bell. The mechanical arrangement for
+effecting this object was simply a steel bar permanently magnetized,
+supported on a pivot and placed with its north end between the two arms
+of a horse-shoe magnet. When the latter was excited by the current the
+end of the bar thus placed was attracted by one arm of the horse-shoe
+and repelled by the other and was thus caused to move in a horizontal
+plane and its further extremity to strike a bell suitably adjusted."
+Thus by 1832 the electric current had been used for sending signals at a
+distance and the electric telegraph had been invented.
+
+[Illustration: FIG. 9.--PROFESSOR HENRY'S ELECTRO-MAGNET, 1832.]
+
+But the electric telegraph was still only a toy. How could it be made a
+practical machine? How could it be used for sending messages in a
+satisfactory manner? Inventors everywhere worked diligently to discover
+a satisfactory method of signaling and many ingenious systems were
+invented. As early as 1837 a telegraph line was established between
+Paddington, England and Drayton--a distance of 13 miles--and messages
+were sent over the wire. But the line failed to give satisfaction and
+its use was discontinued. The honor of inventing the first really
+practical and useful system of electrical telegraphy was at last won by
+an American, S. F. B. Morse, a painter and professor of literature in
+the University of the City of New York. In 1832 Morse began to think
+about a plan for recording signals sent by electricity and by 1837 he
+was about ready to take out a patent for making signals "by the
+mechanical force of electro-magnetic motion." Morse was a poor man and
+he lacked the means of conducting his experiments. He was fortunate,
+however, in making the acquaintance and gaining the confidence of Alfred
+Vail, a student of the University. Vail furnished the money for the
+experiments and assisted Morse in perfecting his system. Indeed some of
+the most original and valuable features of Morse's system were invented
+by young Vail and not by Morse. In the face of much discouragement and
+bad luck Morse and Vail worked patiently on together and by 1843 their
+invention was completed.
+
+[Illustration: FIG. 10.--THE KEY USED BY MORSE.]
+
+The main feature of Morse's system was to use the electric current for
+sending an alphabetical code consisting of certain combinations of "dots
+and dashes." The "dots" were simply clicking sounds and the "dashes"
+were simply intervals between the clicking sounds. The sounds were made
+by closing and breaking the current by means of a key or button (Fig.
+10). If the sender of the message pressed upon the key and immediately
+released it he made at the other end of the line a sharp click which was
+called a "dot," and a single dot according to the code was the letter E.
+If the sender of the message pressed upon the key and held it down for a
+moment he made what was called a "dash," and a single dash according to
+the code was the letter T. Thus by means of "dots and dashes" any
+letter of the alphabet could be speedily sent.
+
+[Illustration: FIG. 11.--MORSE'S TELEGRAPHIC INSTRUMENT.]
+
+Morse applied to Congress to aid him in his plans and in 1843 he secured
+an appropriation of $30,000 for establishing a telegraph line between
+Baltimore and Washington. Morse and Vail now hurried the great work on
+and by May, 1844, the wires had been stretched between the two cities
+and the instruments were ready for trial. And such heavy, clumsy affairs
+the instruments (Fig. 11) were! "The receiving apparatus weighed 185
+pounds and it required the strength of two strong men to handle it. At
+the present day an equally effective magnet need not weigh more than
+four ounces and might be carried in the vest pocket." But, awkward and
+clumsy as it was, the new telegraph did its work well. On May 24, 1844,
+Morse sent from Washington the historic message, "What hath God
+wrought?" (Fig. 12) and in the twinkling of an eye it was received by
+Vail at Baltimore, forty miles away.
+
+[Illustration: FIG. 12.--THE FIRST TELEGRAPHIC MESSAGE SENT FROM
+WASHINGTON TO BALTIMORE, MAY 24, 1844.]
+
+The Morse system proved to be profitable as well as successful and after
+1844 the electric telegraph was soon in general use in all parts of the
+world. In the United States cities were rapidly connected by wire and by
+1860 all the principal places in the country could communicate with each
+other by telegraph. In 1861, a telegraph line extended across the
+continent and connected New York and San Francisco. Five years later,
+thanks to the perseverance and energy of Cyrus W. Field, of New York,
+the Old World and the New were joined together by a telegraphic cable
+passing through the waters of the Atlantic from a point on the coast of
+Ireland to a point on the coast of Newfoundland. With the laying of this
+cable, in 1866, all parts of the world were brought into telegraphic
+communication and it seemed that the last step in the development of the
+message had been taken.
+
+But the story of the Message did not end with the invention of the
+telegraph and the laying of the Atlantic cable. Almost as soon as
+inventors had learned how to send a current along a wire and make
+signals at a distance they began trying experiments to see if they could
+not also send sounds, especially the sound of the human voice, along a
+wire; as soon as they had made the _telegraph_ they began to try to make
+the _telephone_.[25] In 1855 Professor Wheatstone of England invented an
+instrument by means of which musical sounds made in one part of a
+building were carried noiselessly along a wire through several
+intervening halls and reproduced at the other end of the wire in a
+distant part of the building. About the same time a Frenchman named
+Bourseul produced a device by which a disk vibrating under the influence
+of the human voice would, by means of an electric current, produce
+similar vibrations of a disk located at a distance.
+
+About 1874 Professor Alexander Graham Bell, of Boston, seized upon an
+idea similar to that of Bourseul's. Bell saw in the vibrating disk a
+resemblance to the drum of the human ear. In imagination he beheld "two
+iron disks, or ear drums, far apart and connected by an electrified
+wire, catching vibrations of sound at one end and reproducing them at
+the other." With this conception in mind he went to work to construct an
+apparatus that would actually catch the sounds of the voice and
+reproduce them at a distance. Bell, like Morse, was without means to
+conduct his experiments, but friends came to his aid and furnished him
+with the necessary money and by 1876 his labors had resulted in making a
+machine that would carry the human voice; he had invented the telephone.
+At first the telephone was only a toy and would operate at only short
+distances, but as improvements were made the distances grew greater and
+greater until at last one could talk in Boston and be heard in Denver,
+or talk in New York and be heard in London. The telephone grew rapidly
+into favor as a means of communication and in a short time it was used
+more than the telegraph. It is estimated that in the entire world about
+ten billion conversations are held over the telephone in the course of a
+single year.
+
+[Illustration: FIG. 13.--PROFESSOR ALEXANDER GRAHAM BELL SPEAKING OVER
+THE FIRST LONG DISTANCE TELEPHONE BETWEEN NEW YORK AND CHICAGO.]
+
+As wonderful as the telephone was it was quickly followed by an
+invention even more wonderful. Almost as soon as men had thoroughly
+mastered the art of sending messages by the aid of wires they set about
+trying to find a way by which messages could be sent long distances
+without any wires at all. In 1889, Heinrich Hertz, a German scientist,
+showed that electric waves could be sent out in all directions just as
+light waves go out in all directions. He also showed how these waves
+might be produced and how they might be detected or caught as they
+passed through space. In 1896, William Marconi, an Italian electrician,
+making use of the facts discovered by Hertz, sent a message a distance
+of 300 feet without the use of wires. This was the first _wireless
+telegraph_. Marconi continued his experiments, sending wireless messages
+between places further and further apart, and by 1911 he was able to
+signal without cables across the Atlantic Ocean.
+
+[Illustration: FIG. 14.--A WIRELESS TELEGRAPH STATION.]
+
+And now it seems that the wireless telegraph is to be followed by an
+invention still more wonderful. Men are now working upon a _wireless
+telephone_. Already it is possible to talk without the aid of wires
+between places so far apart as Newark and Philadelphia, and many
+inventors believe that it is only a matter of time when the wireless
+telephone will be used side by side with the wireless telegraph.
+
+
+FOOTNOTES:
+
+[21] In the payment of the postage no stamps were as yet used. Indeed
+the postage stamp is a late invention. Postage stamps were not used in
+England until the year 1840, while in the United States they were not
+regularly used until 1847.
+
+[22] In 1840, the English government following the recommendations of
+Sir Rowland Hill, adopted throughout the United Kingdom a uniform rate
+of one penny for letters not exceeding half an ounce in weight, and
+after this cheap postage became the rule in all countries.
+
+[23] The verb telegraph means to write at a distance afar off.
+
+[24] As there are only 24 letters in the Greek alphabet, the last group
+was one letter short, but this did not interfere with the working of the
+system.
+
+[25] Just as the word telegraph means to "write afar off," so the word
+telephone means to "sound afar off."
