Chapter 4

A Knight in Action

Our early Anglo-Saxon fathers fought with swords, spears, axes, and a heavy, single-edged knife. The sword was especially the weapon of the horseman, and was not carried by anyone under the rank of thane. The infantry bore the other weapons. The early Anglo-Saxons do not appear to have used the bow and arrow, though in later times the long bow was an important weapon in England. The Anglo-Saxons of olden times were not strong in cavalry. Saxon warriors carried round or oval shields made of wood and covered with leather. Suits of metal armor were worn for defense.

The gallant knights of the Middle Ages fought on horseback, as they went about protecting the weak, redressing the wrongs of the injured, and upholding right against might. They were clad in armor of metal, with swords buckled to their sides. Mail armor of interlinked metallic rings was used until the beginning of the fourteenth century. From this time to the beginning of the seventeenth century, armor was made of solid plates of metal. After 1600, armor was gradually replaced by a new agent of warfare, against which it was no protection. Likewise the shield, the dagger, and the bow gave way, though the long bow continued in use as an English weapon until the close of Queen Elizabeth's reign.

An Archer of the Fifteenth Century

The invention of gunpowder was one of the most far-reaching events of all history. This terrific substance has not only revolutionized warfare, but has changed the current of human history itself. It is not known who invented gunpowder, or when it was first used. It is a compound of saltpetre, charcoal, and sulphur; the proportions in which these three ingredients are mixed vary in different countries and in different kinds of powders. It seems likely that powder was invented in the Far East, perhaps in China. Saltpetre comes, for the most part, from China and India, on whose vast plains it is found mixed with the soil. An ordinary wood fire kindled on ground containing saltpetre would bring the saltpetre into contact with charcoal, and thereby practically produce powder. It is probable that the discovery of the explosive occurred in this accidental way. Fireworks were used in China from a very early date, but it is doubtful if the Chinese, or any other nation of Asia, used gunpowder as a propelling force. It was left for the Western nations to develop and give practical value to the discovery of the Chinese.

Our first knowledge of powder as an agency of war dates from about the year 700 A.D., when it was used by the Byzantine emperors in defending Constantinople against the Saracens. It was employed there, however, not as a propelling force, but in the form of rockets or a fiery liquid called Greek fire. Its first real use in Europe as a power for propulsion was in Spain, where the Moors and the Christians both used some kind of artillery as early as the twelfth century after Christ. Gunpowder was first introduced into England by Roger Bacon, a British scientist, who was born early in the thirteenth century. He probably did not discover its properties independently, but by reading ancient manuscripts. Owing to the crude and uncertain methods of making gunpowder, it did not attain much value until Berthold Schwarz, a German monk, at about 1320 A.D. introduced an improved method of manufacture. The improved powder thus made was first used in England by King Edward III in his war against the Scotch in 1327. It was perhaps used on the continent of Europe earlier than this, but the occasions are uncertain. The tubes from which the missiles were propelled were called "crakeys of war."

Spenser called cannon "those devilish iron engines." They were probably used for the first time in field warfare by the English in the battle at Crécy, a small town in France, where on August 26, 1346, the English defeated the French. The artillery seemed to have been used in this battle merely to frighten the horses of the enemy, and the cannon were laughed at as ingenious toys.

From the Battle of Crécy onward, the use of gunpowder spread rapidly throughout Europe, the Russians being the last to adopt it. Saltpetre, at first used in its natural state, began to be produced artificially, and then the manufacture of powder extended among the nations. During the French Revolution, according to Carlyle, the revolutionists were driven to such extremities for want of powder that they scraped old cellars seeking material for its manufacture. Many recent improvements have been made in the production of gunpowder, the most important resulting in the smokeless powder.

Before the introduction of cannon using gunpowder as a propelling force, various machines were used in warfare for hurling missiles. Large stones and heavy darts or arrows were thrown by means of tightly twisted ropes, like the action of a bow, or through the aid of a lever and sling. Various names were applied to these weapons, the chief of which were the ballista and the catapult. The ballista hurled stones by means of a twisted cord or a lever; the catapult by darts or arrows could throw a projectile half a mile. Both machines were used by the Romans with great effect, in both defensive and offensive warfare. In destroying the wall of a besieged town, the Romans used a battering-ram. It consisted of a beam of wood with a mass of bronze or iron on the end resembling a ram's head. In its earliest form, the battering-ram was beaten against the wall by the soldiers; later it was suspended in a frame and made to swing with ropes. Another kind moved on rollers, the swinging movement being given to it also by means of ropes. The beam of the ram was from sixty to one hundred and twenty feet long, the head sometimes weighed more than a ton, and as many as a hundred men were necessary to swing it. For the protection of the soldiers using it, a wooden roof covered it, and the whole was mounted on wheels. Scarcely any wall could resist the continued blows of the battering-ram. The Romans were the most effective in the use of this engine, though they borrowed it from the Greeks.

The first cannon were clumsy and comparatively inefficient. They were made of wooden bars held together with iron hoops, and they shot balls of stone. Cannon of bronze were next made, and in the latter part of the fifteenth century iron cannon came into use. The next improvement was the production of cannon of steel, and for some years past the best artillery has been made of this material. After stone balls ceased to be used, round balls of iron were utilized. These in time gave way to cylindrical projectiles of steel. Originally cannon were loaded at the muzzle, but in recent years breech-loading devices have been developed, so that now all of the best modern guns are loaded from the rear.

Within the last twenty-five years, rapid-fire guns have been developed. These have a mechanism by which the breech is opened and closed again by a single motion of a lever. The loading with projectile and powder is also done with one motion. The rapidity of firing varies from two hundred shots per minute in the smallest guns to one shot in two minutes in the largest. The largest British cannon are nearly eighteen inches in calibre (diameter of bore), weigh a hundred tons, are thirty-five feet long, shoot a shell weighing nearly a ton, consume at each charge 450 pounds of powder, and have the power of penetrating solid iron armor plate to the depth of almost two feet, at a distance of one thousand yards. At least a year and a quarter is required for making one of the great, heavy guns, and often a longer time. The cost of constructing one of the largest English cannon is about $117,000, and it costs about $175 to fire the gun once. Some of the most powerful cannon may be relied upon to hit an object ten feet high at a distance of about nine thousand yards. In battle, however, owing to conditions of atmosphere and the limitations of human vision, fire would rarely be opened at a greater distance than three thousand yards, or not quite two miles.

Guns discharged by machinery have been introduced within the last half-century. The fire from machine guns is practically continuous. Several kinds have been invented and improved by various persons. One of the best types of this kind of ordnance is the Gatling gun, invented in 1860 by Dr. R. J. Gatling, of Indianapolis. It consists of a number of parallel barrels, usually ten, grouped around and fastened to a central shaft. Each barrel has its own mechanism for firing. As the barrels revolve, loaded cartridges are fed into them by machinery and the empty cartridges are ejected. By means of an automatic mechanism, the bullets may be scattered over such an arc in front as may be desired, or concentrated upon a narrower range. The Gatling gun can fire at the rate of 1200 shots per minute; it literally hails bullets.

The greatest name connected with the manufacture of modern cannon is that of Herr Alfred Krupp, of Germany, who was born at Essen in 1812 in humble circumstances. He erected the first Bessemer steel works in Germany in the city of his birth, and was the pioneer in the introduction of steel for the manufacture of heavy guns. He believed in the utility of steel when the great governments of the earth had no faith in it. The works at Essen cover in all about one thousand acres, and in them twenty thousand persons find employment. To Krupp Germany owed much, and was not negligent in paying him honor. His factory supplied artillery to nearly all the nations of Europe. He died in July, 1887, and was succeeded in the management of the works by his son Alfred, who also died recently. The plant still continues in operation.

Musketeer and Pikeman of the Early Seventeenth Century

The first portable or hand gun consisted of a simple iron or brass tube fastened to a straight stock of wood. Horsemen used the first guns, and fired them by placing the end of the stock against the breast and letting the barrel rest on a fork fastened to the saddle. The gun was discharged by applying a lighted match to a touch-hole in the top of the barrel. One kind of powder was used for priming; another for firing. Before the invention of cartridges, the powder and bullets were loaded separately at the muzzle, with some kind of packing between. The colonial rifles in America were loaded in this way. In a fight at close quarters, after a gun had been once discharged, the soldier had to fight with his sword. About the middle of the seventeenth century, the bayonet was invented, taking its name from the town of Bayonne, in France, where the inventor lived.

The lighted match which soldiers originally carried for igniting their guns gave way to the flint and steel; and in 1807 a Scotch clergyman named Forsyth obtained a patent which led to the invention of the percussion cap. This improvement revolutionized the mechanism of firearms. Many improvements have been made recently in arms, so that cartridges containing cap, powder, and projectile are fed automatically into guns so delicately constructed that they have great carrying power, precision, and rapidity.

From the dawn of human existence man has sought by some method or other to overcome natural barriers of water. The idea of the ship is as old almost as the race itself. The most primitive form of vessel was the raft. In prehistoric ages men made vessels by hollowing out the trunks of trees, either with fire or with such crude tools as they possessed. The Latin poet Virgil mentions "hollowed alders" used for boats, and indeed canoes were made from hollowed tree trunks as long ago as the Stone Age. The next step forward in the art of shipbuilding was the bark canoe. In countries where bark is scarce, small vessels were made of skins, felt, or canvas covered with pitch. In process of time, boats were made by fastening timbers together, and in this method the basic principle of modern shipbuilding was reached.

It is the relation of ships to purposes of war that interests us here. When the curtain rose for the drama of civilization in Egypt five thousand years ago, men were fighting at sea. The oldest ships of which we have knowledge were Egyptian. The vessels of war were then propelled by oarsmen, who were protected from the missiles of the enemy by planks. On the Egyptian war-galleys there was often a projecting bow to which was attached a metal head for ramming the vessels of the enemy.

Our knowledge of Greek fighting ships—thanks to Greek literature—is fairly full. In the time of Homer, about ten centuries before Christ, Greek men-of-war carried crews of from fifty to one hundred and twenty men, nearly all of whom took part in the labor of rowing. A military boat called the "bireme" came into use in Greece about six or seven centuries before Christ. The word means a vessel with two rows or banks of oarsmen on each side, one row above the other. This disposition of rowers was evidently for the purpose of securing the largest possible number in the least possible space. It is probable that the Greeks did not originate the bireme, but borrowed the idea from the Phœnicians or possibly from Egypt. When Athens was at the zenith of her glory, the principal war vessel was the "trireme," a ship with three rows of oarsmen to the side, each rising above another. Larger ships were subsequently constructed with four, five, and even sixteen banks of rowers to a side, tier above tier.

The Romans, although they were so powerful in land warfare, were not strong in naval achievement until after the First Punic War. In this war they learned the art of naval construction from their enemies, the Carthaginians. A Carthaginian "quinquereme," or boat with five banks of oars, drifted to the Roman coast. The Romans copied it, set up frames on dry land in which crews were taught to row, and in sixty days from the time the trees were felled they had built and manned a fleet. Later the Romans used grappling hooks with which they bound together their own and an opposing ship. They then boarded the enemy's vessel and carried on the fight at close quarters. These tactics gave the Romans command of the sea, and their war galley came to be the supreme object of terror in the naval history of Roman days.

Sails and wind superseded rowers as the motive force of ships. Then came steam. But after gunpowder and steam had worked a revolution in the modes of naval combat, vessels of war continued to be made of wood.

The first fight between iron ships in the history of the world was fought on the ninth of March, 1862, in Hampton Roads, near Norfolk, Virginia, during the Civil War in America. The battle was the combat between theMerrimacand theMonitor. This engagement marked the end of wooden navies. Thenceforth the nations of earth were to make their warships of iron and steel.

Among the largest battleships built for the United States navy are theDelawareand theNorth Dakota. Each of these battleships is five hundred and ten feet long, a little more than eighty-five feet wide, sinks to the depth of nearly twenty-seven feet in the water, and travels at the rate of twenty-one knots per hour. Each vessel weighs twenty thousand tons, and is armed with ten great guns a foot in diameter at the mouth. TheNorth Dakotarequired 4688 tons of steel armor at a cost of more than four hundred dollars per ton. Each of its great twelve-inch guns cost nearly $110,000, weighs fifty-two tons, and hurls a projectile weighing 850 pounds a distance of twelve miles. Three hundred and eighty-five pounds of powder are consumed at a single discharge. At a distance of more than a mile and a half the projectiles of theNorth Dakotawill penetrate steel armor to a depth of nearly twenty inches. When these projectiles leave the guns, they fly through the air at the rate of 2,800 feet in a second. When one hundred shots have been fired from one of these guns, it is worn so that it will be useless until repaired. The cost of a single discharge from one of these guns is about $350.

Sub-marine navigation has always been attended by the most woeful catastrophes, but in spite of numerous accidents the development of the submarine boat has progressed uninterruptedly. Each new model presents new preventive devices. Flasks of oxylithic powder are carried for purifying the air in the water-tight compartments in which the crews live while the boat is below the surface of the water. There is also a special apparatus for signalling other vessels or the shore, in case of danger. In 1904 three vessels, designated X, Y, and Z, were completed, which could achieve submersion in the short space of two minutes. The boats were armed with six torpedoes each. France owns the largest fleet of under-water warships in the world. England stands next, and the United States government is third.

CHAPTER VIII

ASTRONOMICAL DISCOVERIES AND INVENTIONS

"When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained, what is man, that thou art mindful of him?" The Hebrew psalmist feels the insignificance of man compared with the infinitude of the heavens. Victor Hugo expresses the opposite thought: "There is one spectacle grander than the sea—that is the sky; there is one spectacle grander than the sky—that is the interior of the soul."

There is nothing more dignified, more sublime, more awful, than a contemplation of the heavens. In point of grandeur, astronomy may be regarded as king of the sciences. It is also their patriarch. Thousands of years before the birth of Christ the priests of Chaldea, from the tops of their flat-roofed temples, studied the stars and laid the foundations of the science of astronomy. The heavens, with their teeming, whirling, circling congregation, obeying laws that have no "variableness neither shadow of turning" do, indeed, "declare the glory of God."

From the earliest times the stars were supposed to influence for good and ill the lives of men. There were supposed to be stars of good luck and of bad omen. The cool, calculating Cassius tells Brutus,

"The fault, dear Brutus, is not in our stars,But in ourselves, that we are underlings."

"The fault, dear Brutus, is not in our stars,

But in ourselves, that we are underlings."

When you look up into the heavens at the flickering dots of light which we call the stars, you are looking at worlds, many of them far larger than our earth. They seem small because of vast distances from us. Our own solar system, great as it is, in comparison with the celestial universe is but a clod in an acre. At the center of our system is the sun, a huge ball of fiery matter 93,000,000 miles from the earth, and as large as 330,000 worlds like ours. Circling around the sun like maddened horses around a race course are eight planets. These planets, with the sun and some comets, constitute our solar system;oursystem, for how many solar systems there are in space no one knows. These planets, in their order outward from the sun, are Mercury, Venus, our Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Of these, Mercury is the smallest and Jupiter is the largest. The following table shows some interesting facts about the planets:

The moon is 240,000 miles from the earth, and it would require nearly 24,500,000 moons to equal the sun in size. Other planets have moons, some of them several. If you lived on the planet Mercury, your annual birthday would come around about once in three of our months. If you had your home out on the border land of the solar system, on the planet Neptune, you would have a birthday once in about 165 years, as we count time on the earth. It will be observed that the closer the planet is to the sun, the faster it travels in its orbit. This fact is due to the power of gravitation toward the sun. This strange influence drives the planets around the sun, and the nearer the planet is to the sun the greater is the power and consequently the faster the revolution. The law of gravitation was discovered by Sir Isaac Newton.

Newton was born in 1642 in Lincolnshire, England. His father was a farmer, and the farmhouse in which the son was born is still preserved. He was educated at a grammar school in Lincolnshire, and later entered Trinity College, Cambridge, from which he was graduated in 1665. Early in life he displayed a great liking for mathematics. Within a few years after he entered college, he had mastered the leading mathematical works of the day and had begun to make some progress in original mathematical investigation.

Newton's great life work—the achievement which insured to his name a place among the immortals—was suggested to him by accident. As the story goes, while he was walking one day in a garden, he saw an apple fall from a tree. He speculated upon the reasons for its falling, and ultimately concluded that the same force which causes an apple to fall from a tree holds the heavenly bodies in their places. Further investigation brought him to the unfolding of this general law of gravitation: "Every body in nature attracts every other body with a force directly as its mass, and inversely as the square of its distance." This law is the greatest law of nature. It is the central fact of the physical universe, the cement of the material world, the mighty, mystic shepherdess of space, that keeps the planets from wandering off alone. It is this awful, silent power reaching out from the enormous mass of the sun, that lashes the planets in their furious race, and yet holds them tightly reined in their orbits.

Newton was one of the greatest mathematicians, scientists, and thinkers in the history of the world. He died at Kensington, England, on March 20, 1727, and was buried in Westminster Abbey, with the illustrious dead of Great Britain.

Sir Isaac Newton

The operation of this law of gravitation pointed the way to the discovery of the planet Neptune, which is considered the greatest triumph of mathematical astronomy since the days of Newton. Prior to the discovery of Neptune, Uranus was the outermost known planet of the solar system. It was noticed that Uranus was being pulled out of its proper path. It was being tugged away by some strange force beyond the edge of the known planetary system. As the result of a skilful and laborious investigation, Leverrier, a young French astronomer, wrote in substance to an assistant in the observatory at Berlin: "Direct your telescope to a point on the ecliptic in the constellation of Aquarius in longitude 326°, and you will find within a degree of that place a new planet, looking like a star of the ninth magnitude, and having a perceptible disk." Leverrier did not know of the existence of such a planet. He calculated its existence, location, and mass from the fact that some such body must be there, to account for the disturbance caused to Uranus. The telescope in the Berlin Observatory was directed to the place designated by Leverrier, and on the night of September 23, 1846, in exact accordance with his prediction and within half an hour after the astronomers had begun looking, Neptune was discovered within less than one degree from the exact spot where Leverrier had calculated it must be. Such are the triumphs of the human mind. Such are the failures of nature to hide her secrets from the inquiry of man, even behind untold millions of miles.

According to the principles of gravitation as unfolded by Newton, the power of attraction decreases directly as the square of the distance between the sun and a planet. Neptune, being on the outer rim of the system and hence farthest away from the sun, moves in its orbit around the sun more sluggishly than any other planet. Life such as we know it on the earth could not exist on Neptune; it would be too cold. The light and heat from the sun on Neptune are only one nine hundredth part of what we get on the earth. But even so, the sunlight falling upon Neptune is equal in power to seven hundred of our full moons. It was thought that Uranus was the last planet of the solar system until Neptune was found. Whether Neptune is the last, or whether other worlds are roaming around beyond it, is not known.

Ptolemy, who was one of the most celebrated astronomers of earlier times, was born in Egypt about a century and a half after Christ. According to the Ptolemaic system of astronomy, which Ptolemy expounded but did not originate, the earth was considered the center of the universe, and around it the other planets and the sun were believed to revolve. A passage in the Bible in which Joshua commanded the sun to stand still indicates that the old Hebrews believed the sun circled around the earth. The Ptolemaic theory did not account for all the facts observed by astronomers, but for nearly fifteen centuries it held practically universal sway over the belief of men, until another thinker set the matter right.

Nicholas Copernicus was born in Prussia, February 19, 1473. He studied mathematics, medicine, theology, and painting, but his greatest achievements were in astronomy. He made holes in the walls of his room, through which he might observe the stars. Copernicus did not believe in the theory of Ptolemy that the earth was the center of the universe, but held that the solar system had for its center the sun, and that around it the planets, including the earth, revolved. In working out this belief, which science has subsequently shown to be correct, he laid the foundations of the modern system of astronomy.

The book in which Copernicus expounded his theory was begun in 1507 and was completed in 1530. He could not be induced to publish it, however, until shortly before his death. On May 24, 1543, he lay dying in Frauenburg. A few hours before his death, when reason, memory, and life were slipping away from him, the first printed copy of his book was borne to Frauenburg and placed in the great astronomer's hands. He touched the book, looked at it for a time, and seemed conscious of what it was. Quickly afterward he lapsed into insensibility and was gone.

Johann Kepler, who was born in Germany in 1571, contributed several important facts to astronomy. He studied the motions and laws of the celestial bodies. Copernicus taught that the planets revolved around the sun in circular orbits, but Kepler discovered that their paths are ellipses. He also found that the nearer the planets are to the sun the faster they travel. Kepler's discoveries were embodied in three great laws of astronomy known as Kepler's laws. These furnished the foundation for Newton's discoveries and are the basis of modern astronomy. Kepler died in November, 1630.

Many of the wonderful discoveries that have been made in the field of astronomy could not have been possible without the telescope, the most important instrument used by astronomers. The first part of the word is the same Greek adverb meaning "afar," found intelegraphandtelephone; the last part is derived from a Greek verb meaning "to see." The telescope, therefore, is an instrument for seeing objects that are far off. It is a long tube With lenses so arranged as to make objects appear much larger than they would to the naked eye. The telescope was invented by a Dutch optician named Hans Lippershey about three hundred years ago. The Italian scientist Galileo, who was born at Pisa in February, 1564, heard of the invention, began studying the principles upon which it depends, and greatly improved it. Galileo was the first to use the telescope for astronomical purposes. With it he discovered the satellites of Jupiter, the spots on the sun, and the hills and valleys of the moon.

Galileo

At the present time the largest telescopes in the world are made and owned in America. The largest is the Yerkes telescope, belonging to the University of Chicago and located on the shores of Lake Geneva, Wisconsin. Microscopes, opera glasses, and other magnifying instruments depend upon the same principles as the telescope.

One of the most astounding of man's tools is the spectroscope, an instrument used for analyzing light. Through a knowledge of chemistry scientists can establish scientific relations between different substances and the light which they emit. By analyzing the light from the heavenly bodies with the aid of the spectroscope, and comparing this result with the light sent out from different known kinds of matter, man can stand on this little flying speck of matter we call the earth and discover of what substances the stars are made.

One of the most interesting questions arising in a study of the heavenly bodies is whether or not any of them besides the earth are inhabited. Is there any good reason for supposing that our pigmy planet, so insignificant compared with many celestial bodies, is the only one containing life? On the other hand, life such as we know it could not exist on some of the other planets. Mercury would be too hot; Neptune too cold. Climatic conditions on Mars are most nearly like those of the earth. Within recent years the telescope has revealed on the surface of Mars a number of peculiar, regular lines. Many scientists hold that these are artificial canals or irrigation ditches, and that the planet must be inhabited. The theory does not seem at all unreasonable. But the most that can be safely said is that if any of the other planets are inhabited, the most likely one is Mars.

CHAPTER IX

THE COTTON-GIN

Another great invention is the cotton-gin. It is great because of the commercial prosperity which it brought to the Southern states; because it cheapened and extended the use of an almost necessary article of life; and because of its effect on American history. The inventor was an American, Eli Whitney.

The wordginis an abbreviation ofengine, and in former days was often used to denote a handy mechanical device of any kind. The cotton-gin is a machine for removing the seed from the fiber of the cotton-plant. Its essential parts are a number of saws which tear the fiber from the seeds, some stiff brushes used to remove the fiber from the saws, and a revolving fan which blows the lighter substance of the cotton away from the saws and brushes. The original cotton-gin has been little changed by improvement since its invention. It seems to be one of those inventions which have been perfected by the inventor himself.

Eli Whitney was born in Westborough, Worcester County, Massachusetts, December 8, 1765. His father was a thrifty farmer. Nature bestowed upon the son marked ability in the use of tools. While he was yet a child, his inventive genius manifested itself. Before he was ten years old, he could use every tool in the farm workshop with the ease and skill of an old workman. He made a violin before he was twelve and later he came to be noted in the neighborhood as a skilful mender of fiddles. He also turned his attention to making nails, which in Revolutionary days were made by hand, and became the best nail-maker in Worcester County. When he was twenty-four years of age, a desire for a college education possessed him. His father agreed to furnish the money to pay for his schooling, with the stipulation that the son should pay it back. He entered Yale, where he was graduated in 1792.

After graduation Whitney went South to act as tutor in a private family. Upon arrival at his destination, he found that the position was already filled. At that time the widow of General Nathanael Greene, who fought in the Revolutionary War, lived near Savannah, Georgia. She had become interested in young Whitney and invited him to make her plantation his home. She noted his inventive skill, and one day when a group of Georgia planters was discussing at her home the desirability of a machine for removing cotton-seeds from the fiber, Mrs. Greene said: "Gentlemen, apply to my friend, Mr. Whitney; he can make anything." Whitney was called in and the planters laid the matter of the machine before him. At this time he had never even seen cotton fiber. But he made up his mind to try what he could do toward solving the problem.

He went to Savannah and searched among the warehouses and flat-boats for samples of cotton. Mrs. Greene encouraged him in his undertaking and gave him a room in the basement of her house for his workshop. Here he shut himself up with his task, and was heard early and late hammering, sawing, and filing. No one was admitted to the room but Mrs. Greene and Phineas Miller, the tutor of Mrs. Greene's children. At the outset Whitney had neither money nor tools. The money was supplied by an old college friend; the tools Whitney made himself. He could procure no wire in Savannah for constructing his machine, and was compelled to make his own, which he did with much perseverance and skill.

In 1793 the gin was sufficiently completed to convince the inventor that it would be a complete success. Mrs. Greene invited a number of distinguished planters and merchants to witness the working of the machine. The spectators were not slow in realizing the success and the significance of the invention. They saw that with this little machine one man could separate as much cotton from the seed in one day as he could separate by hand in a whole winter. With the gin the cotton grown on a large plantation could be separated in a few days; by hand, the separation would require a hundred workmen for several months.

One dark night some unscrupulous persons broke open the shed in which the unfinished machine had been placed and carried it away. Filled with rage and despair at the wrong which had been done him, Whitney left Georgia and went to Connecticut to complete his invention. But he had scarcely left Savannah when two other claimants for the honor of the invention appeared in Georgia. A few weeks later a gin very closely resembling Whitney's came out. His stolen gin was doubtless used as a model by these false claimants.

On March 14, 1794, Whitney received a patent on his gin. Phineas Miller, who had become the husband of Mrs. Greene, entered into a partnership with Whitney for managing the new invention. Whitney was to manufacture the gins in the North and Miller was to furnish the capital and attend to the interests of the business in the South. They planned not to sell machines or patent rights, but to make and own the gins, loaning them to planters for a rental of one pound in every three pounds of cotton ginned. They would have been wiser if they had manufactured and sold the machines outright. In the first place, it required a larger capital than the firm had to manufacture the necessary number of machines. In the second place, no one firm could make gins fast enough to supply the rapidly increasing demand, and consequently great encouragement was given to infringements on the patent rights. Unending troubles beset the new firm. Whitney himself was a victim to severe illness in the winter of 1794. Scarlet fever raged that year in New Haven, Connecticut, where the manufacturing was being done, and many of the workmen in the gin factory were unable to work. In 1795 Whitney was again seized with severe sickness, and to add to the vexations of the business, the books, papers, and machinery were destroyed by fire. Besides all this, rival claimants circulated a report that Whitney's gin ruined the fiber of the cotton, and that for this reason cotton ginned by the patent process was discriminated against in the markets of England. Another gin which did its work by crushing the seeds between rollers and leaving the crushed seeds in the fiber was represented as superior to Whitney's machine.

Eli Whitney

In speaking of his troubles Whitney said: "The difficulties with which I have had to contend have originated principally in the want of a disposition in mankind to do justice. My invention was new and distinct from every other; it stood alone. It was not interwoven with anything before known; and it can seldom happen that an invention or improvement is so strongly marked, and can be so clearly and specifically identified; and I have always believed that I should have had no difficulty in causing my rights to be respected, if it had been less valuable and been used only by a small portion of the community. But the use of this machine being immensely profitable to almost every planter in the cotton districts, all were interested in trespassing on the patent right, and each kept the other in countenance.... At one time but few men in Georgia dared to come into court and testify to the most simple facts within their knowledge relative to the use of the machine. In one instance I had great difficulty in proving that the machine had been used in Georgia, although at the same moment there were three separate sets of this machinery in motion within fifty yards of the building in which the court sat, and all so near that the rattle of the wheels was distinctly heard on the steps of the court house."

Whitney never received fair and proper compensation for his invention. The machine itself was stolen; others sought to rob him of his honor; he was opposed by an unlimited train of vexations; and after the expiration of his patent he was never able to secure a renewal.

The effect of the invention of the cotton-gin was far-reaching, industrially and historically. In 1807, at a session of the United States District Court held in Savannah, Georgia, the inventor finally obtained judgment against the persons who had stolen his invention. In the opinion rendered in favor of Whitney, Judge Johnson said of the cotton-gin: "Is there a man who hears us who has not experienced its utility? The whole interior of the, Southern states was languishing, and its inhabitants were emigrating for the want of some object to engage their attention and employ their industry, when the invention of this machine at once opened new views to them which set the whole country in active motion. Individuals who were depressed with poverty and sunk in idleness have suddenly risen to wealth and respectability. Our debts have been paid off, our capitals have increased, and our lands have trebled themselves in value. We cannot express the weight of the obligation the country owes to this invention. The extent of it cannot now be seen. Some faint presentiment may be formed from the reflection that cotton is rapidly supplanting wool, flax, silk, and even furs, in manufactures, and may one day profitably supply the use of specie in our East India trade. Our sister states also participate in the benefits of this invention; for besides affording the raw material for their manufactures, the bulkiness and quantity of the article afford a valuable employment for their shipping."

In the South "Cotton is king." The rise of the cotton industry dates from the invention of Eli Whitney's cotton-gin. Before its invention the labor of removing the seed from the fiber was so tedious that the growth of the cotton was not profitable. Partly because of this fact and partly because the Revolutionary War was just over, the South lay dormant; its plantations were heavily mortgaged, its people were moving away in streams. Then came a little machine that awoke the South from its sleep and made it rouse itself. It brought energy, hope, and prosperity, where before were languor, indifference, and stagnation. It increased the exportation of American cotton from less than 190,000 pounds in 1791 to 41,000,000 pounds in 1803.

From the historical point of view the invention of the cotton-gin was tremendous in its influence. This machine multiplied by many times the demand in the South for slave labor and made slaves far more profitable. One writer has said of Whitney: "He was, through his invention, probably one of the most potent agencies for the extension of slavery and the terrible struggle that marked the first half-century of our nation's existence. While he was quietly sleeping in his grave, the very earth was shaken with the tread of contending armies that he had done more than any other one man to call forth to battle; for there is little doubt that but for the invention of the cotton-gin slavery would not have lived out the century of the Revolution." Macaulay says: "What Peter the Great did to make Russia dominant, Eli Whitney's invention of the cotton-gin has more than equaled in its relation to the power and progress of the United States." In the light of the wonderful, widespread material growth and prosperity that have come to the whole of our country in recent years, Macaulay's statement is overdrawn. But as matters were when it was written by the great Englishman, it was probably true.

Whitney achieved much success as the inventor of improved methods of manufacturing firearms. He was the first to conceive the plan of making the different parts of firearms by machinery, so that any part of a weapon would fit any other like weapon equally well. This principle has made possible the production of cheap watches, clocks, and sewing machines. He died in New Haven, Connecticut, January 8, 1825.

CHAPTER X

ANÆSTHETICS

If those inventions and discoveries out of which have come widespread safety, happiness, or prosperity to mankind are to be considered great, then Dr. Morton's discovery of anæsthetics and its application to surgery is entitled to a high place among the world's discoveries and inventions. The pain that has been destroyed, the lives that have been saved, the sorrow that has been averted, give their testimony to the value of this discovery to humanity.

An anæsthetic is administered to produce temporary insensibility to pain. At least something of anæsthetics was known to the ancients. Homer mentions nepenthe, a potion which was said to make persons forget their pains and sorrows. The word appears occasionally in literature. In "Evangeline" Longfellow refers to it in this line:

"Crown us with asphodel flowers, that are wet with the dews of nepenthe."

Virgil and other classical writers mention a mythical river Lethe which was supposed to surround Hades. Souls passing over to the happy fields of Elysium first drank from this river, whose waters caused them to forget their sorrows. Milton speaks of the mythical stream in the following passage from "Paradise Lost:"

"Far off from these a slow and silent stream,Lethe, the river of oblivion, rolls her watery labyrinth."

"Far off from these a slow and silent stream,

Lethe, the river of oblivion, rolls her watery labyrinth."

Herodotus wrote that it was the practice of the Scythians to inhale the vapors of a certain kind of hemp to produce intoxication. The use of the mandrake plant as an anæsthetic is spoken of as far back as Pliny, the Roman historian. The sleep-producing effects of the mandragora or mandrake are alluded to by Shakespeare. He also frequently mentions in a general way draughts that act as anæsthetics, without making clear their specific natures. An old Chinese manuscript indicates that a physician of that country named Hoa-tho in the third century after Christ used a preparation of hemp as an anæsthetic in surgical operations. Although the ancients had knowledge of anæsthetics of one kind or other, the practice of anæsthesia never became general, and surgeons of the ancient world appear to have looked upon it with disfavor.

When in modern times Joseph Priestley, the English scientist (born in 1733, died 1804) gave great impetus to chemical research by his discoveries in that science, the nature of gases and vapors was more and more closely studied. The belief soon sprang up that many gases and vapors would ultimately become of great value in medicine and surgery. In 1800 Sir Humphry Davy experimented with nitrous oxide gas, called "laughing gas," and discovered its anæsthetic qualities. He suggested its use in surgery, but for practically half a century his suggestion passed unheeded. Other scientists experimented with greater or less success, seeking to find something that would alleviate physical pain; but to Dr. William T. G. Morton, an American, belongs the credit for the practical introduction of anæsthetics into modern surgery.

Dr. Morton was born in Charlton, Massachusetts, August 9, 1819. His ancestors were of Scotch extraction. He passed his early years in farm work. At the age of thirteen he entered an academy at Oxford, Massachusetts, where he remained only a few months, attending school thereafter at Northfield and Leicester. His father's financial condition caused him to leave school in 1836 and enter the employ of a publishing firm in Boston. Deciding to engage in the practice of dentistry, in 1840 he took a course in the Baltimore College of Dental Surgery. Two years afterward he began the practice of his profession in Boston. As dentistry at that time was in its beginnings as a distinct profession, Dr. Morton took up, in addition to it, the study of general medicine and surgery in the Harvard Medical School.

In the days prior to the use of anæsthetics, the operations of dental surgery were attended by much pain. Dr. Morton began seeking some means for alleviating it. In the course of his investigations he became acquainted with the effects of sulphuric ether as a local anæsthetic, and frequently used this drug in minor operations. On one occasion he applied it with unusual freedom in the treatment of a very sensitive tooth. Observing how completely the tissues were benumbed by the ether, he conceived the idea of bringing the entire system under its influence, thereby producing temporary insensibility in all the sensory nerves. The most serious problem with which he had to deal was the manner of applying the ether. Although the soporific tendencies of both ether and nitrous oxide gas were well known, it had not been proved that they could be inhaled in sufficiently large quantities, or, if so, that they would produce perfect insensibility. After a long series of experiments with various animals, Dr. Morton succeeded in fully establishing the narcotic power of ether.

On October 16, 1846, he made his first public demonstration of the new discovery in the operating room of the Massachusetts General Hospital, in Boston, when he painlessly removed a tumor from the jaw of a patient. This operation was wholly convincing to the medical profession, and created profound public interest. Dr. Morton was brought into immediate prominence. A meeting of the leading physicians of Boston was held to choose an appropriate name for the new process. A long list of words was presented, from which Dr. Morton selected the termletheon, related to the Lethe of Virgil and the classical writers. The wordsanæstheticandanæsthesiawere coined from the Greek by Dr. Oliver Wendell Holmes, the American poet and physician, who was then living in Boston. The words proposed by Dr. Holmes have become the established terms of the subject, superseding theletheonof the discoverer.
