Benjamin Franklin's activity and resource in the field of invention really partook of the intellectual breadth of the man of whom Turgot wrote:

"Eripuit c?lo fulmen, sceptrumque tyrannis."

"He snatched the thunderbolt from heaven,

And the sceptre from the hands of tyrants."

And of which bit of verse Franklin once dryly remarked, that as to the thunder, he left it where he found it, and that more than a million of his countrymen co-operated with him in snatching the sceptre. Those persons who knew Franklin, the inventor, only as the genius to whom we owe the lightning-rod, will be amazed at the range of his activity. For half a century his mind seems to have been on the alert concerning the why and wherefore of every phenomenon for which the explanation was not apparent. Nothing in nature failed to interest him. Had he lived in an era of patents he might have rivalled Edison in the number of his patentable devices, and had he chosen to make money from such devices, his gains would certainly have been fabulous. As a matter of fact, Franklin never applied for a patent, though frequently urged to do so, and he made no money by his inventions. One of the most popular of these, the Franklin stove, which device, after a half-century of disuse, is now again popular, he made a present to his early friend, Robert Grace, an iron founder, who made a business of it. The Governor of Pennsylvania offered to give Franklin a monopoly of the sale of these stoves for a number of years. "But I declined it," writes the inventor, "from a principle which has ever weighed with me on such occasions, viz.: That as we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously. An ironmonger in London, however, assuming a good deal of my pamphlet (describing the principle and working of the stove), and working it up into his own, and making some small change in the machine, which rather hurt its operation, got a patent for it there, and made, as I was told, a little fortune by it."

The Franklin Stove.

The complete list of inventions, devices, and improvements of which Franklin was the originator, or a leading spirit and contributor, is so long a one that a dozen pages would not suffice for it. I give here a brief summary, as compiled by Parton in his excellent "Life of Franklin." "It is incredible," Franklin once wrote, "the quantity of good that may be done in a country by a single man who will make a business of it and not suffer himself to be diverted from that purpose by different avocations, studies, or amusements." As a commentary upon this sentiment, here is a catalogue of the achievements of Benjamin Franklin that may fairly come under the title of inventions:

He established and inspired the Junto, the most useful and pleasant American club of which we have knowledge.

He founded the Philadelphia Library, parent of a thousand libraries, and which marked the beginning of an intellectual movement of endless good to the whole country.

He first turned to great account the engine of advertising, an indispensable element in modern business.

He published "Poor Richard," a record of homely wisdom in such shape that hundreds of thousands of readers were made better and stronger by it.

He created the post-office system of America, and was the first champion of a reformed spelling.

He invented the Franklin stove, which economized fuel, and suggested valuable improvements in ventilation and the building of chimneys.

He robbed thunder of its terrors and lightning of some of its power to destroy.

He founded the American Philosophical Society, the first organization in America of the friends of science.

He suggested the use of mineral manures, introduced the basket willow, promoted the early culture of silk, and pointed out the advisability of white clothing in hot weather.

He measured the temperature of the Gulf Stream, and discovered that northeast storms may begin in the southwest.

He pointed out the advantage of building ships in water-tight compartments, taking the hint from the Chinese, and first urged the use of oil as a means of quieting dangerous seas.

Besides these great achievements, accomplished largely as recreation from his life work as economist and statesman, Benjamin Franklin helped the whole race of inventors by a remark that has been of incalculable value and comfort to theorists and dreamers the world over. When someone spoke rather contemptuously in Franklin's presence of Montgolfier's balloon experiments, and asked of what use they were, the great American replied in words now historic: "Of what use is a new-born babe?"

"This self-taught American," said Lord Jeffrey, in the Edinburgh Review of July, 1806, "is the most rational, perhaps, of all philosophers. He never loses sight of common sense in any of his speculations. No individual, perhaps, ever possessed a greater understanding, or was so seldom obstructed in the use of it by indolence, enthusiasm, or authority. Dr. Franklin received no regular education; and he spent the greater part of his life in a society where there was no relish and no encouragement for literature. On an ordinary mind, these circumstances would have produced their usual effects, of repressing all sorts of intellectual ambition or activity, and perpetuating a generation of incurious mechanics; but to an understanding like Franklin's, we cannot help considering them as peculiarly propitious, and imagine that we can trace back to them distinctly almost all the peculiarities of his intellectual character."

Franklin's Birthplace, Boston.

The main outlines of Franklin's life and career are so familiar to everyone, that I may as well pass at once to the story of his work as an inventor. We all know, or ought to know, that Benjamin, the fifteenth child of Josiah Franklin, the Boston soap-boiler, was born in that town on the 17th of January, 1706, and established himself as a printer in Philadelphia in 1728. That he prospered and founded the Gazette a few years later, and became Postmaster of Philadelphia in 1737; that after valuable services to the Colonies as their agent in England, he was appointed United States Minister at the Court of France upon the Declaration of Independence; and that in 1782 he had the supreme satisfaction of signing at Paris the treaty of peace with England by which the independence of the Colonies was assured. That he died full of honors at Philadelphia in April, 1790, and that Congress, as a testimony of the gratitude of the Thirteen States and of their sorrow for his loss, appointed a general mourning throughout the States for a period of two months.

Franklin Entering Philadelphia.

The great invention or discovery which entitles Benjamin Franklin to rank at the head of American inventors was, of course, the identification of lightning with electricity, and his suggestion of metallic conductors so arranged as to render the discharge from the clouds a harmless one. In order to appreciate the originality and value of this discovery, it is necessary to review briefly what the world knew of the subject at that day.

For a hundred years before Franklin's time, electricity had been studied in Europe without much distinct progress resulting. A thousand experiments had been performed and described. Gunpowder had been exploded by the spark from a lady's finger, and children had been insulated by hanging them from the ceiling by silk cords. A tolerable machine had been devised for exciting electricity, though most experimenters still used a glass tube. Several volumes of electrical observations and experiments had appeared, and yet what had been done was little more than a repetition on a larger scale, and with better means, of the original experiment of rubbing a piece of amber on the sleeve of the philosopher's coat. Experimenters in 1745 could produce a more powerful spark and play a greater variety of tricks with it than Dr. Gilbert, the English experimenter of 1600, but that was about all the advantage they had over him.

So-called experts had attempted, with more or less satisfaction to themselves, to answer the question addressed by the mad Lear to poor Tom: "Let me talk with this philosopher. What is the cause of thunder?" Pliny thought he had explained it when he called it an earthquake in the air. Dr. Lister announced that lightning was caused by the sudden ignition of immense quantities of fine floating sulphur. Jonathan Edwards, in his diary of 1722, records the popular impression of the day upon this subject: "Lightning," he says, "seem to be an almost infinitely fine combustible matter, that floats in the air, that takes fire by sudden and mighty fermentation, that is some way promoted by the cool and moisture, and perhaps attraction of the clouds. By this sudden agitation, this fine floating matter is driven forth with a mighty force one way or other, whichever way it is directed, by the circumstances and temperature of the circumjacent air; for cold and heat, density and rarity, moisture and dryness, have almost an infinitely strong influence upon the fine particles of matter. This fluid matter thus projected, still fermenting to the same degree, divides the air as it goes, and every moment receives a new impulse by the continued fermentation; and as its motion received its direction, at first, from the different temperature of the air on different sides, so its direction is changed, according to the temperature of the air it meets with, which renders the path of the lightning so crooked."

Even this explanation was a daring bit of speculation in Jonathan Edwards, for thunder and lightning were then commonly regarded as the physical expression of God's wrath against the insects He had created.

Mr. Peter Collinson, the London agent of the library that Franklin had founded in Philadelphia in 1732, was accustomed to send over with the annual parcel of books any work or curious object that chanced to be in vogue in London at the time. In 1746 he sent one of the new electrical tubes with a paper of directions for using it. The tubes then commonly used were two feet and a half long, and as thick as a man could conveniently grasp. They were rubbed with a piece of cloth or buckskin, and held in contact with the object to be charged. Franklin had already seen one of these tubes in Boston, and had been astonished by its properties. No sooner, therefore, was it unpacked at the Library, than he repeated the experiments he had seen in Boston, as well as those described by Collinson. The subject completely fascinated him. He gave himself up to it. Procuring other tubes, he distributed them among his friends and set them all rubbing. "I never," he writes in 1747, "was before engaged in any study that so totally engrossed my attention and my time as this has done; for what with making experiments when I can be alone, and repeating to my friends and acquaintances, who, from the novelty of the thing, come continually in crowds to see them; I have during some months past had little leisure for anything else."

Franklin claimed no credit for what he achieved in electricity. During the winter of 1746-7 he and his friends experimented frequently, and observed electrical attraction and repulsion with care. That electricity was not created, but only collected by friction, was one of their first conjectures, the correctness of which they soon demonstrated by a number of experiments. Before having heard of the Leyden jar coated with tin-foil, these Philadelphia experimenters substituted granulated lead for the water employed by Professor Maschenbroeck. They fired spirits and lighted candles with the electric spark. They performed rare tricks with a spider made of burnt cork. Philip Syng mounted one of the tubes upon a crank and employed a cannon-ball as a prime conductor, thus obtaining the same result without much tedious rubbing of the tube.

The summer of 1747 was devoted to preparing the province for defence. But during the following winter the Philadelphians resumed their experiments. The wondrous Leyden jar was the object of Franklin's constant observation. His method of work is well shown in his own account of an experiment during this winter. The jar used was Maschenbroeck's original device of a bottle of water with a wire running through the cork.

"Purposing," writes Franklin, "to analyse the electrified bottle, in order to find wherein its strength lay, we placed it on glass, and drew out the cork and wire, which for that purpose had been loosely put in. Then, taking the bottle in one hand, and bringing a finger of the other near its mouth, a strong spark came from the water, and the shock was as violent as if the wire had remained in it, which showed that the force did not lie in the wire. Then, to find if it resided in the water, being crowded into and condensed in it, as confined by the glass, which had been our former opinion, we electrified the bottle again, and placing it on glass, drew out the wire and cork as before; then, taking up the bottle, we decanted all its water into an empty bottle, which likewise stood on glass; and taking up that other bottle, we expected, if the force resided in the water, to find a shock from it. But there was none. We judged then that it must either be lost in decanting or remain in the first bottle. The latter we found to be true; for that bottle on trial gave the shock, though filled up as it stood with fresh unelectrified water from a tea-pot. To find, then, whether glass had this property merely as glass, or whether the form contributed anything to it, we took a pane of sash glass, and laying it on the hand, placed a plate of lead on its upper surface; then electrified that plate, and bringing a finger to it, there was a spark and shock. We then took two plates of lead of equal dimensions, but less than the glass by two inches every way, and electrified the glass between them, by electrifying the uppermost lead; then separated the glass from the lead, in doing which, what little fire might be in the lead was taken out, and the glass being touched in the electrified parts with a finger, afforded only very small pricking sparks, but a great number of them might be taken from different places. Then dexterously placing it again between the leaden plates, and completing a circle between the two surfaces, a violent shock ensued; which demonstrated the power to reside in glass as glass, and that the non-electrics in contact served only, like the armature of a loadstone, to unite the force of the several parts, and bring them at once to any point desired; it being the property of a non-electric, that the whole body instantly receives or gives what electrical fire is given to, or taken from, any one of its parts.

"Upon this we made what we called an electrical battery, consisting of eleven panes of large sash glass, armed with thin leaden plates, pasted on each side, placed vertically, and supported at two inches' distance on silk cords, with thick hooks of leaden wire, one from each side, standing upright, distant from each other, and convenient communications of wire and chain, from the giving side of one pane to the receiving side of the other; that so the whole might be charged together with the same labor as one single pane."

In 1748 Franklin, being then forty-two years old, and in the enjoyment of an ample income from his business as printer and publisher, sold out to his foreman, David Hall, and was free to devote himself wholly to his beloved experiments. He had built himself a home in a retired spot on the outskirts of Philadelphia, and with an income which in our days would be equivalent to $15,000 or $20,000 a year, he was considered a fairly rich man. Having thus settled his business affairs in a manner which proved that he knew perfectly well what money was worth, he took up his electrical studies again and extended them from the machine to the part played in nature by electricity. The patience with which he observed the electrical phenomena of the heavens, the acuteness displayed by him in drawing plausible inferences from his observations, and the rapidity with which he arrived at all that we now know of thunder and lightning, still excite the astonishment of all who read the narratives he has left us of his proceedings. During the whole winter of 1748-49 and the summer following, he was feeling his way to his final conclusions on the subject. Early in 1749 he drew up a series of fifty-six observations, entitled "Observations and Suppositions towards forming a new Hypothesis for explaining the several Phenomena of Thundergusts." Nearly all that he afterward demonstrated on this subject is anticipated in this truly remarkable paper, which was soon followed by the most famous of all his electrical writings, that entitled "Opinions and Conjectures concerning the Properties and Effects of the Electrical Matter, and the Means of preserving Buildings, Ships, etc., from Lightning; arising from Experiments and Observations made at Philadelphia, 1749."

Franklin sets forth in this masterly paper the similarity of electricity and lightning, and the property of points to draw off electricity. It is this treatise which contains the two suggestions that gave to the name of Franklin its first celebrity. Both suggestions are contained in one brief passage, which follows the description of a splendid experiment, in which a miniature lightning-rod had conducted harmlessly away the electricity of an artificial thunder-storm.

"If these things are so," continues the philosopher, after stating the results of his experiment, "may not the knowledge of this power of points be of use to mankind in preserving houses, churches, ships, etc., from the stroke of lightning, by directing us to fix on the highest part of those edifices upright rods of iron, made sharp as a needle and gilt to prevent rusting, and from the foot of those rods, a wire down the outside of the building into the ground, or down round one of the shrouds of a ship, and down her side till it reaches the water? Would not these pointed rods probably draw the electrical fire silently out of a cloud before it came nigh enough to strike, and thereby secure us from that most sudden and terrible mischief?"

The second of these immortal suggestions was one that immediately arrested the attention of European electricians when the paper was published. It was in these words:

"To determine the question, whether the clouds that contain lightning are electrified or not, I would propose an experiment to be tried where it may be done conveniently. On the top of some high tower or steeple, place a kind of sentry-box, big enough to contain a man and an electric stand. From the middle of the stand let an iron rod rise and pass, bending out of the door, and then upright twenty or thirty feet, pointed very sharp at the end. If the electrical stand be kept clean and dry, a man standing on it, when such clouds are passing low, might be electrified and afford sparks, the rod drawing fire to him from a cloud. If any danger to the man should be apprehended (though I think there would be none), let him stand on the floor of his box, and now and then bring near to the rod the loop of a wire that has one end fastened to the leads, he holding it by a wax handle; so the sparks, if the rod is electrified, will strike from the rod to the wire and not affect him."

A friend once asked Franklin how he came to hit upon such an idea. His reply was to quote an extract from the minutes he kept of the experiments he made. This extract, dated November 7, 1749, was as follows: "Electrical fluid agrees with lightning in these particulars: 1. Giving light. 2. Color of the light. 3. Crooked direction. 4. Swift motion. 5. Being conducted by metals. 6. Crack or noise in exploding. 7. Subsisting in water or ice. 8. Rending bodies it passes through. 9. Destroying animals. 10. Melting metals. 11. Firing inflammable substances. 12. Sulphurous smell. The electric fluid is attracted by points. We do not know whether this property is in lightning. But since they agree in all the particulars wherein we can already compare them, is it not probable they agree likewise in this? Let the experiment be made."

In this discovery, therefore, there was nothing of chance; it was a legitimate deduction from patiently accumulated facts.

It was not until the spring of 1752 that Franklin thought of making his suggested experiment with a kite. The country around Philadelphia presents no high hills, and he was not aware till later that the roof of any dwelling-house would have answered as well as the peak of Teneriffe. There were no steeples in Philadelphia at that day. The vestry of Christ Church talked about erecting a steeple, but it was not begun until 1753. On the 15th of June, 1752, Franklin decided to fly that immortal kite. Wishing to avoid the ridicule of a failure, he took no one with him except his son, who, by the way, was not the small boy shown in countless pictures of the incident, but a stalwart young man of twenty-two. The kite had been made of a large silk handkerchief, and fitted out with a piece of sharpened iron wire. Part of the string was of hemp, and the part to be held in the hand was of silk. At the end of the hempen string was tied a key, and in a convenient shed was a Leyden jar in which to collect some of the electricity from the clouds. When the first thunder-laden clouds reached the kite, there were no signs of electricity from Franklin's key, but just as he had begun to doubt the success of the experiment, he saw the fibres of the hempen string begin to rise. Approaching his hand to the key, he got an electric spark, and was then able to charge the Leyden jar and get a stronger shock. Then the happy philosopher drew in his wet kite and went home to write his modest account of one of the most notable experiments made by man.

Franklin's fame as the first to suggest the identity of lightning and electricity would have been safe, however, even without the famous kite-flying achievement. A month before that June thunderstorm his suggestions had been put into practice in Europe with complete success. Mr. Peter Collinson, to whom Franklin addressed from time to time long letters about his experiments and conjectures, had caused them to be read at the meetings of the Royal Society, of which he (Collinson) was a member. That learned body, however, did not deem them worthy of publication among its transactions, and a letter of Franklin's containing the substance of his conjectures respecting lightning was laughed at. The only news that reached Philadelphia concerning these letters was that Watson and other English experimenters did not agree with Franklin. It was only in May, 1751, that a pamphlet was finally published in London, entitled "New Experiments and Observations in Electricity, made at Philadelphia, in America." A copy having been presented to the Royal Society, Watson was requested to make an abstract of its contents, which he did, giving generous praise to the author.

Before the year came to a close Franklin was famous. There was something in the drawing down, for mere experiment, of the dread electricity of heaven that appealed not less powerfully to the imagination of the ignorant than to the understanding of the learned. And the marvel was the greater that the bold idea should have come from so remote a place as Philadelphia. By a unanimous vote the Royal Society elected Franklin a member, and the next year bestowed upon him the Copley medal. Yale College and then Harvard bestowed upon him the honorary degree of Master of Arts.

The Franklin Penny.

As might have been expected, there was no lack of opposition to the new doctrine of lightning-rods. Every new movement of radical character is denounced more or less fiercely. The last years of Newton's life were perplexed by the charge that his theory of gravitation tended to "materialize" religion. Insuring houses against fire was opposed as an interference with the prerogatives of deity. The establishment of the Royal Society was opposed upon the ground that the study of natural philosophy, grounded, as it was, upon experimental evidence, tended to weaken the force of evidence not so founded; and this objection was deemed of sufficient weight to call for serious answer. Franklin's daring proposal to neutralize the "artillery of heaven," of course could not escape, and the impiety of lightning-rods was widely discussed, often with acrimony. Mr. Kinnersley, one of Franklin's friends, who lectured for several years upon electricity, when advertising the outline of his subject always announced his intention to show that the erection of lightning-rods was "not chargeable with presumption nor inconsistent with any of the principles either of natural or revealed religion." Quincy relates in his "History of Harvard College," that in November, 1755, a shock of earthquake having been felt in New England, a Boston clergyman preached a sermon on the subject, in which he contended that the lightning-rods, by accumulating the electricity in the earth, had caused the earthquake. Professor Winthrop, of Harvard, thought it worth while to defend Franklin. "In 1770," Mr. Quincy adds, "another Boston clergyman opposed the use of the rods on the ground that, as the lightning was one of the means of punishing the sins of mankind, and of warning them from the commission of sin, it was impious to prevent its full execution." And to this attack also Professor Winthrop replied. Apparently Franklin himself thought it wise to conciliate the opposition of some so-called religious people of the day, for an account of the lightning-rod which appears in Poor Richard's Almanac for 1753, written probably by Franklin, begins as follows: "It has pleased God in his Goodness to Mankind, at length to discover to them the means of securing their Habitations and other Buildings from Mischief by Thunder and Lightning."

Franklin bore his honors with the most remarkable modesty. It was in June that he flew his first kite, but not until October that he sent to Mr. Collinson an account of the experiment, and even then he described the manner of making and flying the kite and omitted all reference to his own success with it. The identity of lightning with electricity having been established by M. Dalibard, he deemed it unnecessary to forward the account of an experiment which, however brilliant, he thought superfluous. Accordingly, we have no narrative by Franklin of the flying of the kite. We owe our knowledge of what occurred on that memorable afternoon to persons who heard Franklin tell the story. Franklin prefaces his description of his kite with these words: "As frequent mention is made in public papers from Europe of the success of the Philadelphia experiment for drawing the electric fire from clouds by means of pointed rods of iron erected on high buildings, it may be agreeable to the curious to be informed that the same experiment has succeeded in Philadelphia, though made in a different and more easy manner, which is as follows." And then we have the description of the kite, the letter ending without reference to what he himself had done with it.

Yet he was far from hiding the pleasure his fame brought him. "The Tatler," he wrote, in 1753, to a friend, "tells us of a girl who was observed to grow suddenly proud, and none could guess the reason, till it came to be known that she had got on a pair of new silk garters. Lest you should be puzzled to guess the cause, when you observe anything of the kind in me, I think I will not hide my new garters under my petticoats, but take the freedom to show them to you in a paragraph of our friend Collinson's last letter, viz.-But I ought to mortify, and not indulge, this vanity; I will not transcribe the paragraph-yet I cannot forbear." Then he quotes the paragraph, which mentions the honors done him by the King of France and the Royal Society.

For twenty years Franklin continued to work at electricity, devoting most of his leisure to his beloved study. The great practical value of the lightning-rod, at one time in the early part of this century somewhat exaggerated, as a perfect protection against harm by lightning, just as electricity was at one time heralded as a panacea for all bodily ailments, has of late years been questioned, but the consensus of scientific opinion still attributes much merit to the device, and the extent of Franklin's services to science in the matter cannot be called into doubt. Others have claimed his discoveries. The Abbé Nolet, of France, has been credited as being the first to note the similarity between electricity and lightning; and M. Romas, of Nerac, France, is said to have used a kite with a copper wire wound around the string, to attract electricity from clouds, some time before Franklin made his experiment. But posterity has ignored these claimants, and Franklin had the happiness of escaping bitter contentions with rivals. In fact, there could hardly have been a quarrel with a man who claimed nothing, who mentioned with honor everybody's achievements but his own, and who recorded his most brilliant observations in the plural, as though he were but one of a band of investigating Philadelphians.

Passing now, to Franklin's connection with the use of oil to still dangerous waves, I had occasion recently to note that Lieutenant W.H. Beehler, of the United States Navy, in writing upon the matter, quotes Franklin's explanation of why oil works so beneficently as the accepted theory. Franklin was greatly interested, when at sea, in studying the matter. Any phenomenon that puzzled him was fit subject for investigation. Let us see how he went about the inquiry. "In 1757," he wrote, "being at sea in a fleet of ninety-six sail bound against Louisburg, I observed the wakes of two of the ships to be remarkably smooth, while all the others were ruffled by the wind which blew fresh. Being puzzled with the differing appearance, I at last pointed it out to our captain and asked him the meaning of it. 'The cooks,' says he, 'have, I suppose, been just emptying their greasy water through the scuppers, which has greased the sides of those ships a little;' and this answer he gave me with an air of some little contempt, as to a person ignorant of what everybody else knew. In my own mind I at first slighted his solution, though I was not able to think of another; but recollecting what I had formerly read in Pliny, I resolved to make some experiment of the effect of oil on water, when I should have opportunity. Afterwards, being again at sea in 1762, I first observed the wonderful quietness of oil on agitated water, in the swinging glass lamp I made to hang up in the cabin, as described in my printed papers. This I was continually looking at and considering, as an appearance to me inexplicable. An old sea captain, then a passenger with me, thought little of it, supposing it an effect of the same kind with that of oil put on water to smooth it, which he said was a practice of the Bermudians when they would strike fish, which they could not see if the surface of the water was ruffled by the wind. The same gentleman told me he had heard it was a practice with the fishermen of Lisbon, when about to return into the river (if they saw before them too great a surf upon the bar, which they apprehended might fill their boats in passing) to empty a bottle or two of oil into the sea, which would suppress the breakers, and allow them to pass safely. A confirmation of this I have not since had an opportunity of obtaining; but discoursing of it with another person, who had often been in the Mediterranean, I was informed that the divers there, who, when under water in their business, need light, which the curling of the surface interrupts by the refractions of so many little waves, let a small quantity of oil now and then out of their mouths, which rising to the surface smooths it, and permits the light to come down to them. All these informations I at times resolved in my mind, and wondered to find no mention of them in our books of experimental philosophy.

"At length being at Clapham where there is, on the common, a large pond, which I observed one day to be very rough with the wind, I fetched out a cruet of oil and dropped a little of it on the water. I saw it spread itself with surprising swiftness upon the surface; but the effect of smoothing the waves was not produced; for I had applied it first on the leeward side of the pond, where the waves were largest, and the wind drove my oil back upon the shore. I then went to the windward side, where they began to form; and there the oil, though not more than a teaspoonful, produced an instant calm over a space several yards square, which spread amazingly, and extended itself gradually, till it reached the lee side, making all that quarter of the pond, perhaps half an acre, as smooth as a looking glass.

"A gentleman from Rhode Island told me it had been remarked that the harbor of Newport was ever smooth while any whaling vessels were in it; which, probably arose from hence, that the blubber, which they sometimes bring loose in the hold, or the leakage of their barrels, might, afford some oil to mix with that water, which, from time to time, they pump out to keep their vessel free, and that some oil might spread over the surface of the water in the harbor and prevent the forming of any waves."

Thus Franklin collected his facts, taking them far and near, and from anybody and everybody. By dint of observation and reflection he finally solved the problem, arriving at the conclusion that "the wind blowing over water thus covered with a film of oil, cannot easily catch upon it, so as to raise the first wrinkles, but slides over it, and leaves it smooth as it finds it."

Another remarkable instance of Franklin's passion for investigation is afforded in the following interesting letter to Sir John Pringle: "When we were travelling together in Holland, you remarked that the canal boat in one of the stages went slower than usual, and inquired of the boatman what might be the reason; who answered that it had been a dry season, and the water in the canal was low. On being asked if it was so low that the boat touched the muddy bottom, he said no, not so low as that, but so low as to make it harder for the horse to draw the boat. We neither of us at first could conceive that, if there was water enough for the boat to swim clear of the bottom, its being deeper would make any difference. But as the man affirmed it seriously as a thing well known among them, and as the punctuality required in their stages was likely to make such difference, if any there were, more readily observed by them than by other watermen who did not pass so regularly and constantly backwards and forwards in the same track, I began to apprehend there might be something in it, and attempted to account for it from this consideration, that the boat in proceeding along the canal must, in every boat's length of her course, move out of her way a body of water equal in bulk to the room her bottom took up in the water; that the water so moved must pass on each side of her, and under her bottom, to get behind her; that if the passage under her bottom was straitened by the shallows, more of the water must pass by her sides, and with a swifter motion, which would retard her, as moving the contrary way; or that, the water becoming lower behind the boat than before, she was pressed back by the weight of its difference in height, and her motion retarded by having that weight constantly to overcome. But, as it is often lost time to attempt accounting for uncertain facts, I determined to make an experiment of this, when I should have convenient time and opportunity.

"After our return to England, as often as I happened to be on the Thames, I enquired of our watermen whether they were sensible of any difference in rowing over shallow or deep water. I found them all agreeing in the fact that there was a very great difference, but they differed widely in expressing the quantity of the difference; some supposing it was equal to a mile in six, others to a mile in three. As I did not recollect to have met with any mention of this matter in our philosophical books, and conceiving that, if the difference should be really great, it might be an object of consideration in the many projects now on foot for digging new navigable canals in this island, I lately put my design of making the experiment in execution, in the following manner.

"I provided a trough of planed boards fourteen feet long, six inches wide, and six inches deep in the clear, filled with water within half an inch of the edge, to represent a canal, I had a loose board of nearly the same length and breadth, that being put into the water, might be sunk to any depth, and fixed by little wedges where I would choose to have it stay, in order to make different depths of water, leaving the surface at the same height with regard to the sides of the trough. I had a little boat in form of a lighter or boat of burden, six inches long, two inches and a quarter wide, and one inch and a quarter deep. When swimming it drew one inch of water. To give motion to the boat, I fixed one end of a long silk thread to its bow, just even with the water's edge, the other end passed over a well-made brass pulley, of about an inch in diameter, turning freely upon a small axis; and a shilling was the weight. Then placing the boat at one end of the trough, the weight would draw it through the water to the other. Not having a watch that shows seconds, in order to measure the time taken up by the boat in passing from end to end of the trough, I counted as fast as I could count to ten repeatedly, keeping an account of the number of tens on my fingers. And, as much as possible to correct any little inequalities in my counting, I repeated the experiment a number of times at each depth of water, that I might take the medium."

The experiment proved the truth of the boatmen's assertions. Franklin found that five horses would be required to draw a boat in a canal affording little more than enough water to float it, which four horses could draw in a canal of the proper depth.

No circumstance, remarks Mr. Parton, was too trifling to engage him upon a series of experiments. At dinner, one day, a bottle of Madeira was opened which had been bottled in Virginia many months before. Into the first glass poured from it fell three drowned flies. "Having heard it remarked that drowned flies were capable of being revived by the rays of the sun, I proposed making the experiment upon these; they were therefore exposed to the sun upon a sieve which had been employed to strain them out of the wine. In less than three hours two of them began by degrees to recover life. They commenced by some convulsive motions of the thighs, and at length they raised themselves upon their legs, wiped their eyes with their forefeet, beat and brushed their wings with their hind feet, and soon after began to fly, finding themselves in Old England without knowing how they came thither. The third continued lifeless till sunset, when, losing all hopes of him, he was thrown away." And upon this he remarks: "I wish it were possible, from this instance, to invent a method of embalming drowned persons in such a manner that they may be recalled to life at any period, however distant; for having a very ardent desire to see and observe the state of America a hundred years hence, I should prefer to any ordinary death being immersed in a cask of Madeira wine, with a few friends, till that time, to be then recalled to life by the solar warmth of my dear country."

Among the studies in natural philosophy of which but little is known to the general public may be mentioned Franklin's experiments with heat at a time when a thermometer was a scientific curiosity. The manner in which he proved that black cloth was not so good a covering for the body in hot weather as white, shows the simplicity of his methods and his faculty for making small means subserve great ends: "I took a number of little square pieces of broadcloth from a tailor's pattern-card, of various colors. There were black, deep blue, lighter blue, green, purple, red, yellow, white, and other colors or shades of colors. I laid them all out upon the snow in a bright sunshiny morning. In a few hours the black, being warmed most by the sun, was so low as to be below the stroke of the sun's rays; the dark blue almost as low, the lighter blue not quite so much as the dark, the other colors less as they were lighter, and the quite white remained on the surface of the snow, not having entered it at all. What signifies philosophy that does not apply to some use? May we not learn from hence that black clothes are not so fit to wear in a hot, sunny climate or season as white ones?" That all summer hats, particularly for soldiers, should be white, and that garden walls intended for fruit should be black, were suggestions put forth as a result of this experiment.

Dr. Small assigns to Franklin the credit of having discovered that repeated respiration imparts to air a poisonous quality similar to that which extinguishes candles and destroys life in mines and wells. "The doctor," he records, "breathed gently through a tube into a deep glass mug, so as to impregnate all the air in the mug with this quality. He then put a lighted bougie (candle) into the mug, and upon touching the air therein the flame was instantly extinguished; by frequently repeating this operation, the bougie gradually preserved its light longer in the mug, so as in a short time to retain it to the bottom of it, the air having totally lost the bad quality it had contracted from the breath blown into it." Upon being consulted with regard to the better ventilation of the House of Commons, he advised that openings should be made near the ceiling, communicating with flues running parallel with the chimneys and close enough to them to be kept warm by their heat. These flues, he recommended, should begin in the cellar, where the air was cool, and the flues being warmed by the hot air of the chimneys, would cause an upward current of air strong enough to expel the vitiated air in the upper part of the house. Franklin's letters at this time are full of the importance of ventilation. Unquestionably, he was among the first who called attention to the folly of excluding fresh air from hospitals and sick-rooms, particularly those of fever patients. As Mr. Parton expresses it, he cleared the pure air of heaven from calumnious imputation and threw open the windows of mankind.

Some inventions of Franklin's have not met with the approval of posterity. For instance, he seems to have had no more success with a reformed spelling of his own devising than laborers in the same field who came after him. He used to say that they alone spelt well who spelt ill, since the so-called bad speller used the letters according to their real value. The illiterate girl who wrote of her bo was more correct, he thought, than the young lady who would blush to omit a superfluous vowel. What was the use of the final letter in muff, and why take the trouble to write tough when tuf would do as well? Had he lived to see Dr. Webster's Dictionary, the lexicographer would have found in him an ardent champion. His reformed alphabet and spelling is an interesting curiosity, but hardly more. Some letters of our alphabet he omitted, only to add new ones. He also changed their order, making o the first letter and m the last. In this connection it may be well to say that Franklin was perhaps the first and foremost American champion of the movement, now so powerful, looking to the displacement of Latin and Greek as the foundations of education. At the very close of his life, in 1789, he issued his famous protest against the study of dead languages. He is reported to have said one evening, when talking about this matter: "When the custom of wearing broad cuffs with buttons first began, there was a reason for it; the cuffs might be brought down over the hands and thus guard them from wet and cold. But gloves came into use, and the broad cuffs were unnecessary; yet the custom was still retained. So likewise with cocked hats. The wide brim, when let down, afforded a protection from the rain and the sun. Umbrellas were introduced, yet fashion prevailed to keep cocked hats in vogue, although they were rather cumbersome than useful. Thus with the Latin language. When nearly all the books of Europe were written in that language, the study of it was essential in every system of education; but it is now scarcely needed, except as an accomplishment, since it has everywhere given place, as a vehicle of thought and knowledge, to some one of the modern tongues."

With all his love of the practical, Franklin was not deficient in a rather delicate wit. I have already had occasion to quote at the beginning of this paper his disclaimer of the honors conferred upon him by Turgot's famous Latin line. Instances of this dry humor may be found all through Sparks's exhaustive biography. I remember one in particular. The merchants of Philadelphia, being at one time desirous to establish an assembly for dancing, they drew up some rules, among which was one "that no mechanic or mechanic's wife or daughter should be admitted on any terms." This rule being submitted to Franklin, he remarked that "it excluded God Almighty, for he was the greatest mechanic in the universe."

Benjamin Franklin's services to the cause of invention by no means ended with his own inventions. One of his greatest services was the part he took in the foundation of the American Philosophical Society, whose object was to bring into correspondence with a central association in Philadelphia all scientists, philosophers, and inventors on this continent and in Europe. Franklin's share in the foundation of this society, which has proved of such vast use, seems to have been largely overlooked by his biographers. Mr. Parton, having mentioned that Franklin founded the society in accordance with his proposal of 1743, adds: "The society was formed and continued in existence for some years. Nevertheless, its success was neither great nor permanent, for at that day the circle of men capable of taking much interest in science was too limited for the proper support of such an organization." The recent historian of the society, Dr. Robert M. Patterson, agrees, however, with Sparks in tracing the origin of the Philosophical Society, which grew into prominence about 1767, back to Franklin's proposal of 1743. After describing the Junto, or Leather Apron Society, formed among Franklin's acquaintance, a sort of debating club of eleven young men, Sparks says: "Forty years after its establishment it became the basis of the American Philosophical Society, of which Franklin was the first president, and the published transactions of which have contributed to the advancement of science and the diffusion of valuable knowledge in the United States." In his first proposal Franklin gave a list of the subjects that were to engage the attention of these New World philosophers. It included investigations in botany; in medicine; in mineralogy and mining; in chemistry; in mechanics; in arts, trades, and manufactures; in geography and topography; in agriculture; and, lest something should have been forgotten, he adds that the association should "give its attention to all philosophical experiments that let light into the nature of things, tend to increase the power of man over matter and multiply the conveniences or pleasures of life." The duties of the secretary of the society were laid down and were arduous, including much foreign correspondence, in addition to the correcting, abstracting, and methodizing of such papers as required it. This office Franklin took upon himself.

Franklin's Grave.

While he lived the proceedings of the society scarcely ever failed of a useful end. Unlike so many original and inventive geniuses, his eminent common sense was as marked as his originality. In the language of his most recent biographer, John Bach McMaster, "whatever he has said on domestic economy or thrift is sound and striking. No other writer has left so many just and original observations on success in life. No other writer has pointed out so clearly the way to obtain the greatest amount of comfort out of life. What Solomon did for the spiritual man, that did Franklin for the earthly man. The book of Proverbs is a collection of receipts for laying up treasure in heaven. 'Poor Richard' is a collection of receipts for laying up treasure on earth."

Robert Fulton.

Robert Fulton, the inventor of the steamboat, or at least the first man to apply the power of the steam-engine to the propulsion of boats in a practical and effective manner, was born in Little Britain, Lancaster County, Pa., 1765, of respectable but poor parents. His father was a native of Kilkenny, Ireland, and his mother came of a fairly well-to-do Irish family, settled in Pennsylvania. He was the third of five children. As a child he received the rudiments of a common education. His vocation showed itself in his earliest years. All his hours of recreation were passed in shops and in drawing. At the time he was seventeen he had become so much of an artist as to make money by portrait and landscape painting in Philadelphia, where he remained until he was twenty-one. After this he went to Washington County and there purchased a little farm on which he settled his mother, his father having died when he was three years old. He returned to Philadelphia, but on his way visited the Warm Springs of Pennsylvania, where he met with some gentlemen who were so much pleased with his painting that they advised him to go to England, where they told him he would meet with West who had then attained great celebrity. Fulton took this advice, and his reception by West, always kindly toward Americans, was such as he had been led to expect. The distinguished painter was so well pleased with him that he took him into his house, where he continued to live for several years. For some time Fulton made painting his chief employment, spending two years in Devonshire, near Exeter, where he made many influential acquaintances, among others the Duke of Bridgewater, famous for his canals, and Lord Stanhope, a nobleman noted for his love of science and his attachment to the mechanic arts. With Lord Stanhope, Fulton held a correspondence for a long time upon subjects in which they were interested.

In 1793, Fulton was engaged in a project to improve inland navigation. Even at that early day it appeared that he had conceived the idea of propelling vessels by steam, and he speaks in his letters of its practicability. In 1794 he obtained from the British Government a patent for improvements in canal locks, and his pursuits at this time appear to have been in this direction. In his preface to a description of his Nautilus, or "plunging" boat, a species of submarine boat, he says that he had resided eighteen months in Birmingham where he acquired much of his knowledge of mechanics. In later years, when in Paris, Fulton sent a large collection of his manuscripts to this country. Unfortunately, the vessel in which they were sent was wrecked, and, while the case was recovered, only a few fragments of the manuscripts could be used. It is owing to this misfortune that we have so few records of Fulton's work at this time.

Birthplace of Robert Fulton. [1]

We know, however, that in 1794 he submitted to the British Society for the Promotion of Arts and Commerce an improvement of his invention for sawing marble, for which he received the thanks of the society and an honorary medal. He invented also, it is thought, about this time, a machine for spinning flax and another for making ropes, for both of which he obtained patents from the British Government. A mechanical contrivance for scooping out earth to form channels for canals or aqueducts, which is said to have been much used in England, was also his invention. The subject of canals appears to have chiefly engaged his attention during these years of the end of the century. He called himself a civil engineer, and under this title published his work on canals, and, in 1795, many essays on the same subject in one of the London journals. He recommended small canals and boats of little burden in a treatise on "Improvement of Canal Navigation," and inclined planes instead of locks, as a means of transporting canal boats from one level to another. His plans were strongly recommended by the British Board of Agriculture. Throughout his course as civil engineer his talent for drawing was of great advantage to him, and the plates annexed to his works are admirable examples of such work. He seems to have neglected his painting till a short time before his death, when he took up the brush again to paint some portraits of his family. During his residence in England he sent copies of his works to distinguished men in this country, setting forth the advantages to be derived from communication by canals.

Having obtained a patent for mill improvements from the British Government, he went to France with the intention of introducing his invention there; but, not meeting with much encouragement, he devoted his time to other matters. Political economy had also some attraction for him, and he wrote a book to show that internal improvements would have a good effect on the happiness of a nation. He not only wished to see a free and speedy communication between the different parts of a large country, but universal free trade between all countries. He thought that it would take ages to establish the freedom of the seas by the common consent of nations, and believed in destroying ships of war, so as to put it out of the power of any nation to control ocean trade. In 1797 he became acquainted with Joel Barlow, the well-known American, then residing in Paris, in whose family he lived for seven years, during which time he learned French and something of German, and studied mathematics and chemistry. In the same year he made an experiment with Mr. Barlow on the Seine with a machine he had constructed to give packages of gunpowder a progressive motion under water and then to explode at a given point. These experiments appear to have been the first in the line of his submarine boats, and are unquestionably the germ of all subsequent inventions in the direction of torpedo warfare.

Want of money to carry out his designs induced him to apply to the French Directory, who at first gave him reason to expect their aid, but finally rejected his plan. Fulton, however, was not to be discouraged, but went on with his inventions, and having made a handsome model of his machine for destroying ships, a commission was appointed to examine his plans, but they also rejected them. He offered his idea to the British Government, still again without success, although a committee was appointed to examine his models. The French Government being changed, and Bonaparte having come to the head of it, Fulton presented an address to him. A commission was appointed, and some assistance given which enabled him to put some of his plans into practice. In the spring of 1801 he went to Brest to make experiments with the plunging boat that he had constructed in the winter. This, as he says, had many imperfections, to be expected in a first machine, and had been injured by rust, as parts which should have been of copper or brass were made of iron.

Notwithstanding these disadvantages, he engaged in a course of experiments which required no less courage than perseverance. From a report of his proceedings to the committee appointed by the French Government we learn that in July, 1801, he embarked with three companions on board of this boat, in the harbor of Brest, and descended to the depth of twenty-five feet, remaining below the surface an hour, in utter darkness, as the candles were found to consume too much of the vital air. He placed two men at the engine, which was intended to give her motion, and one at the helm, while he, with a barometer before him, kept her balanced between the upper and lower waters. He could turn her round while under the water, and found that in seven minutes he had gone about a third of a mile. During that summer Fulton descended under water with a store of air compressed into a copper globe, whereby he was enabled to remain under water four hours and twenty minutes. The success of these experiments determined him to try the effect of his invention on the English war-ships, then daily near the harbor of Brest-France and England being then at war. He made his own bombs. For experimental purposes a small vessel was anchored in the harbor, and with a bomb containing about twenty pounds of powder, he approached within about two hundred yards, struck the vessel, and blew her into atoms. A column of water and fragments were sent nearly one hundred feet into the air. This experiment was made in the presence of the prefect of the department and a multitude of spectators. During the summer of 1801 Fulton tried to use his bombs against some of the English vessels, but was not successful in getting within range. The French Government refused to give him further encouragement.

The English had some information concerning the attempts that their enemies were making, and the anxiety expressed induced the British Minister to communicate with Fulton and try to secure to England his services. In this he was successful, and Fulton went to London, where he arrived in 1804, and met Pitt and Lord Melville. When Mr. Pitt first saw a drawing of a torpedo with a sketch of the mode of applying it, and understood what would be the effect of the explosion, he said that if it were introduced into practice it could not fail to annihilate all navies.

Fulton Blowing Up a Danish Brig.

But from the subsequent conduct of the British ministry it is supposed that they never really intended to give Fulton a fair opportunity to try the effect of his submarine engines. Their object may have been to prevent these devices getting into the hands of an enemy. Several experiments were made, and some of them were failures, but on October 15, 1805, he blew up a strong-built Danish brig of two hundred tons burden, which had been provided for the experiment and which was anchored near the residence of Pitt. The torpedo used on this occasion contained one hundred and seventy pounds of powder. In fifteen minutes from the time of starting the machinery the explosion took place. It lifted the brig almost entire and broke her completely in two; in one minute nothing was to be seen of her but floating fragments. Notwithstanding the complete success of this experiment, the British ministry seems to have had nothing to do with Fulton. The inventor was rather discouraged at this lack of appreciation and, after some further experiments, he sailed for New York in December, 1806.

In this country Fulton devoted himself at once to his project of submarine warfare and steam navigation. So far from being discouraged by his failure to impress Europe with the importance of his torpedoes, his confidence was unshaken, because he saw that his failures were to be attributed to trivial errors that could easily be corrected. He induced our Government to give him the means of making further experiments, and invited the magistracy of New York and a number of citizens to Governor's Island where were the torpedoes and the machinery with which his experiments were to be made. In July, 1807, he blew up, in the harbor of New York, a large brig prepared for that purpose. He also devised at this time a number of stationary torpedoes, really casks of powder, with triggers that might be caught by the keel of any passing vessel. In March, 1810, $5,000 were granted by Congress for further experiments in submarine explosions. The sloop of war, Argus, was prepared for defence against the torpedoes after Fulton had explained his mode of attack. This defence was so complete that Fulton found it impracticable to do anything with his torpedoes. Some experiments were made, however, with a gun-harpoon and cable cutter, and after several attempts a fourteen-inch cable was cut off several feet below the surface of the water.

Fulton was, during all these experiments, much pressed for money, and apparently was making no headway toward the use of his submarine engines in a profitable way. It was in despair of getting our Government to make an investment in this direction that he finally turned to the problem of navigation by steam. He had the valuable co-operation in his new work of Chancellor Livingston, of New Jersey, who, while devoting much of his own time and means to the advancement of science, was fond of fostering the discoveries of others. He had very clear conceptions of what would be the great advantages of steamboats on the navigable rivers of the United States. He had already, when in Paris, applied himself at great expense to constructing vessels and machinery for that kind of navigation. As early as 1798 he believed that he had accomplished his object, and represented to the Legislature of New York that he was possessed of a mode of applying the steam-engine to a boat on new and advantageous principles; but that he was deterred from carrying it into effect by the uncertainty of expensive experiments, unless he could be assured of an exclusive advantage should it be successful. The Legislature in March, 1798, passed an act vesting him with the exclusive right and privilege of navigating all kinds of boats which might be propelled by the force of fire or steam on all the waters within the territory of New York for the term of twenty years, upon condition that he should within a twelve-month build such a boat, whose progress should not be less than four miles an hour.

John Fitch's Steamboat at Philadelphia.

Livingston, as soon as the act had passed, built a boat of about thirty tons burden, to be propelled by steam. Soon after he entered into a contract with Fulton, by which it was agreed that a patent should be taken out in the United States in Fulton's name. Thus began the preparations for the first practical steamboat. All the experiments were paid for by Chancellor Livingston, but the work was Fulton's. In 1802, in Paris, he began a course of calculations upon the resistance of water, upon the most advantageous form of the body to be moved, and upon the different means of propelling vessels which had been previously attempted. After a variety of calculations he rejected the proposed plan of using paddles or oars, such as those already used by Fitch; likewise that of ducks' feet, which open as they are pushed out and shut as they are drawn in; also that of forcing water out of the stern of the vessel. He retained two methods as worthy of experiment, namely, endless chains with paddle-boards upon them, and the paddle-wheel. The latter was found to be the most promising, and was finally adopted after a number of trials with models on a little river which runs through the village of Plombières, to which he had retired in the spring of 1802, to pursue his experiments without interruption.

Fulton's First Experiment with Paddle-wheels.

It was now determined to build an experimental boat, which was completed in the spring of 1803; but when Fulton was on the point of making an experiment with her, an accident happened to the boat, the woodwork not having been framed strongly enough to bear the weight of the machinery and the agitation of the river. The accident did the machinery very little injury; but they were obliged to build the boat almost entirely anew. She was completed in July; her length was sixty-six feet and she was eight feet wide. Early in August, Fulton addressed a letter to the French National Institute, inviting the members to witness a trial of his boat, which was made before the members, and in the presence of a great multitude of Parisians. The experiment was entirely satisfactory to Fulton, though the boat did not move altogether with as much speed as he expected. But he imputed her moving so slowly to the extremely defective machinery, and to imperfections which were to be expected in the first experiment with so complicated a machine; the defects were such as might be easily remedied.

Such entire confidence did he acquire from this experiment that immediately afterward he wrote to Messrs. Boulton & Watt, of Birmingham, England, ordering certain parts of a steam-engine to be made for him, and sent to America. He did not disclose to them for what purpose the engine was intended, but his directions were such as would produce the parts of an engine that might be put together within a compass suited for a boat. Mr. Livingston had written to his friends in this country, and through their assistance an act was passed by the Legislature of the State of New York, on April 5, 1803, by which the rights and exclusive privileges of navigating all the waters of that State, by vessels propelled by fire or steam, granted to Livingston by the Act of 1798, as already mentioned, were extended to Livingston and Fulton, for the term of twenty years from the date of the new act. By this law the time of producing proof of the practicability of propelling by steam a boat of twenty tons capacity, at the rate of four miles an hour, with and against the ordinary current of the Hudson, was extended two years, and by a subsequent law, the time was extended to 1807.

Very soon after Fulton's arrival in New York he began building his first American boat. While she was constructing, he found that her cost would greatly exceed his calculations. He endeavored to lessen the pressure on his own finances by offering one-third of the rights for a proportionate contribution to the expense. It was generally known that he made this offer, but no one was then willing to afford aid to his enterprise.

In the spring of 1807, Fulton's first American boat was launched from the shipyard of Charles Brown, on the East River. The engine from England was put on board, and in August she was completed, and was moved by her machinery from her birthplace to the Jersey shore. Livingston and Fulton had invited many of their friends to witness the first trial, among them Dr. Mitchell and Dr. M'Neven, to whom we are indebted for some account of what passed on this occasion. Nothing could exceed the surprise and admiration of all who witnessed the experiment. The minds of the most incredulous were changed in a few minutes. Before the boat had gone a quarter of a mile, the greatest unbeliever must have been converted. The man who, while he looked on the expensive machine, thanked his stars that he had more wisdom than to waste his money on such idle schemes, changed his mind as the boat moved from the wharf and gained speed, and his complacent expression gradually stiffened into one of wonder.

This boat, which was called the Clermont, soon after made a trip to Albany. Fulton gives the following account of this voyage in a letter to his friend, Mr. Barlow:

Departure of the Clermont on her First Voyage.

"My steamboat voyage to Albany and back, has turned out rather more favorable than I had calculated. The distance from New York to Albany is one hundred and fifty miles; I ran it up in thirty-two hours, and down in thirty. I had a light breeze against me the whole way, both going and coming, and the voyage has been performed wholly by the power of the steam-engine. I overtook many sloops and schooners beating to windward, and parted with them as if they had been at anchor. The power of propelling boats by steam is now fully proved. The morning I left New York there were not, perhaps, thirty persons in the city who believed that the boat would even move one mile an hour, or be of the least utility; and while we were putting off from the wharf, which was crowded with spectators, I heard a number of sarcastic remarks. This is the way in which ignorant men compliment what they call philosophers and projectors. Having employed much time, money, and zeal, in accomplishing this work, it gives me, as it will you, great pleasure to see it fully answer my expectations. It will give a cheap and quick conveyance to the merchandise on the Mississippi, Missouri, and other great rivers, which are now laying open their treasures to the enterprise of our countrymen; and although the prospect of personal emolument has been some inducement to me, yet I feel infinitely more pleasure in reflecting on the immense advantage that my country will derive from the invention."

Soon after this successful voyage, the Hudson boat was advertised and established as a regular passage-boat between New York and Albany. She, however, in the course of the season, met with several accidents, from the hostility of those engaged in the ordinary navigation of the river, and from defects in her machinery, the greatest of which was having her water-wheel shafts of cast-iron, which was insufficient to sustain the great power applied to them. The wheels also were hung without any support for the outward end of the shaft, which is now supplied by what are called the wheel-guards.

At the session of 1808 a law was passed to prolong the time of the exclusive right to thirty years; it also declared combinations to destroy the boat, or wilful attempts to injure her, public offences, punishable by fine and imprisonment. Notwithstanding her misfortunes, the boat continued to run as a packet, always loaded with passengers, for the remainder of the summer. In the course of the ensuing winter she was enlarged, and in the spring of 1808 she again began running as a packet-boat, and continued it through the season. Several other boats were soon built for the Hudson River, and also for steamboat companies formed in different parts of the United States. On February 11, 1809, Fulton took out a patent for his inventions in navigation by steam, and on February 9, 1811, he obtained a second patent for some improvements in his boats and machinery.

About the year 1812 two steam ferry-boats were built under the direction of Fulton for crossing the Hudson River, and one of the same description for the East River. These boats were what are called twin-boats, each of them being two complete hulls united by a deck or bridge. They were sharp at both ends, and moved equally well with either end foremost, so that they crossed and recrossed without losing any time by turning about. He contrived, with great ingenuity, floating docks for the reception of these boats, and a means by which they were brought to them without a shock. These boats, were the first of a fleet which has since carried hundreds of millions of passengers to and from New York.

From the time the first boat was put in motion till the death of Fulton, the art of navigating by steam advanced rapidly to that perfection of which he believed it capable; the boats performed each successive trip with increased speed, and every year improvements were made. The last boat built by Fulton was invariably the best, the most convenient, and the swiftest.

At the beginning of 1814 a number of the citizens of New York, alarmed at the exposed situation of their harbor, had assembled with a view to consider whether some measures might not be taken to aid the Government in its protection. This assembly had some knowledge of Fulton's plans for submarine attack, and knew that he contemplated other means of defence. It deputed a number of gentlemen to act for it, and these were called the Coast and Harbor Committee. Fulton exhibited to this committee the model and plans for a vessel of war, to be propelled by steam, capable of carrying a strong battery, with furnaces for red-hot shot, and which, he represented, would move at the rate of four miles an hour. The confidence of the committee in this design was confirmed by the opinions of many of our most distinguished naval commanders, which he had obtained in writing, and exhibited to the committee. They pointed out many advantages which a steam vessel of war would possess over those with sails only.

The National Legislature passed a law in March, 1814, authorizing the President of the United States to cause to be built, equipped, and employed one or more floating batteries for the defence of the waters of the United States. A sub-committee of five gentlemen was appointed to superintend the building of the proposed vessel, and Fulton, whose spirit animated the whole enterprise, was appointed the engineer. In June, 1814, the keel of this novel and mighty engine was laid, and in October she was launched from the New York yard of Adam and Noah Brown. The scene exhibited on this occasion was magnificent. It happened on one of our bright autumnal days. Multitudes of spectators crowded the surrounding shores. The river and bay were filled with vessels of war, dressed in all their colors in compliment to the occasion. By May, 1815, her engine was put on board, and she was so far completed as to afford an opportunity of trying her machinery. On the 4th of July, in the same year, the steam-frigate made a passage to the ocean and back, a distance of fifty-three miles, in eight hours and twenty minutes, by the mere force of steam. In September she made another passage to the sea, and having at this time the weight of her whole armament on board, she went at the rate of five and a half miles an hour, upon an average, with and against the tide. The superintending committee gave in their report a full description of the Fulton the First, the honored name this vessel bore.

The last work in which the active and ingenious mind of Fulton was engaged was a project for the modification of his submarine boat. He presented a model of this vessel to the Government, by which it was approved; and under Federal authority he began building one; but before the hull was entirely finished his country had to lament his death, and the mechanics he employed were incapable of proceeding without him.

During the whole time that Fulton had thus been devoting his talents to the service of his country, he had been harassed by lawsuits and controversies with those who were violating his patent rights, or intruding upon his exclusive grants. The State of New Jersey had passed a law which operated against Fulton, without being of much advantage to those interested in its passage, inasmuch as the laws of New York prevented any but Fulton's boats to approach the city of New York. Its only operation was to stop a boat owned in New York, which had been for several years running to New Brunswick, under a license from Messrs. Livingston and Fulton. A bold attempt was therefore made to induce the Legislature of the State of New York to repeal the laws which they had passed for the protection of their exclusive grant to Livingston and Fulton. The committee reported that such repeal might be passed consistently with good faith, honor, and justice! This report being made to the House, it was prevailed upon to be less precipitate than the committee had been. It gave time, which the committee would not do, for Fulton to be sent for from New York. The Assembly and Senate in joint session examined witnesses, and heard him and the petitioner by counsel. The result was that the Legislature refused to repeal the prior law, or to pass any act on the subject. The Legislature of the State of New Jersey also repealed their law, which left Fulton in the full enjoyment of his rights. This enjoyment was of very short duration; for on returning from Trenton, after this last trial, he was exposed on the Hudson, which was very full of ice, for several hours. He had not a constitution to encounter such exposure, and upon his return found himself much indisposed. He had at that time great anxiety about the steam-frigate, and, after confining himself to the house for a few days, went to give his superintendence to the workmen employed about her. Forgetting his ill-health in the interest he took in what was doing on the frigate, he remained too long exposed on a bad day to the weather. He soon felt the effects of this imprudence. His indisposition returned upon him with such violence as to confine him to his bed. His illness increased, and on February 24, 1815, it ended his life.

It was not known that Fulton's illness was dangerous till a very short time before his death. Means were immediately taken to testify, publicly, the universal regret at his loss, and respect for his memory. The corporation of the city of New York, the different literary institutions and other societies, assembled and passed resolutions expressing their estimation of his worth, and regret at his loss. They also resolved to attend his funeral, and that the members should wear badges of mourning for a certain time. As soon as the Legislature, which was then in session at Albany, heard of the death of Fulton, they expressed their participation in the general sentiment by resolving that the members of both Houses should wear mourning for some weeks.

In 1806 Fulton married Harriet Livingston, a daughter of Walter Livingston, a relative of his associate, Chancellor Livingston. He left four children; one son, Robert Barlow Fulton, and three daughters. Fulton was in person considerably above medium height; his face showed great intelligence. Natural refinement and long intercourse with the most polished society of Europe and America had given him grace and elegance of manner.
