the foundation of the science of Dynamics, or the action of forces, as they relate to motion. His support of the Copernican system, by which he drew down upon himself the rage of the inquisition, and his consequent imprisonment are well known; as also his subsequent abjuration of the opinions which he had so zealously espoused, and which exhibits a mortifying instance of human imbecility. See Edin. Ency. C. To Dr. FRANKLIN belongs the honour of having discovered what is termed plus and minus electricity; the explanation of the Leyden phial; and the identity of lightning and electricity. These are his most brilliant discoveries, and, with his profound knowledge of political economy, his sound judgment, and the excellent practical tendency of his writings, have probably gained him a higher reputation abroad, as a writer, and a man of genius, than any other American has ever enjoyed. ib. D. Sir RICHARD ARKWRIGHT was bred a barber; but his great improvements in the machines for spinning cotton have discovered genius and talents of the first order. His most important invention is the substitution of machinery for the human finger. This great invention has caused a complete revolution in the art of cotton spinning. Speaking of this distinguished mechanic, Professor Griscom has the following remark :-" It would be difficult I think, to name an individual, with the whole civilized world before us, whose inventive powers are better entitled to the grateful applauses of his country." Vide Year in Europe, Vol. 2. E. "Mr. WATT's improvements in the steam engine, were so great as to give it almost a new form. Instead of the general practice, which was to condense the steam in the same cylinder in which the piston works, Mr. Watt, after many trials, fell on a plan of saving much of the waste heat and fuel, by causing the steam to pass into a separate vessel for condensation, so that the iron cylinder in which the rarified steam was admitted, to cause the next stroke of the engine, was never cooled at all, and no heat wasted in again bringing it to a proper temperature. This was the first great improvement made by Mr. Watt, and he calculated that it saved nearly two thirds of the steam generated, and fuel consumed." At a meeting recently held in London, for the purpose of erecting a monument to the memory of Watt, the president of the Royal Society (Sir Humphrey Davy) pays the following tribute to his genius. "He was obliged to bring all the mechanical powers, and all the resources of his own fertile mind into play; he had to convert rectilineal into rotatory motion, and to invent parallel motion. After years of intense labour, he obtained what he wished for, and at last placed the machine entirely under the power of the mechanic, and gave perfection to a series of combinations unrivalled for the genius and sagacity displayed in their invention, and for the new power they have given to civilized man." London Mech. Magazine, Vol. 1. F. The great discovery of our countryman, FULTON, in the application of steam to the purposes of navigation, can hardly be considered of less importance, than the previous inventions of Watt. Mr. Fulton presents one of the most remarkable instances of perseverance under difficulties and discouragements, which can be found in the history of the arts. Had he not possessed "a dauntless soul to persevere, Though mountains rise, though Alps on Alps appear," he never would have succeeded in bringing to perfection an improvement which will cause his name to be remembered, as long as the Hudson or the Mississippi, shall roll their waves. His friend, Mr.Colden, has endeavoured to do justice to his character; but no eulogium can be too great for a man who has rendered such signal service to his country and the arts. I might have added to this list, the name of another American, whose extraordinary discoveries in regard to the properties of steam, are at present the theme of panegyric on both sides of the Atlantic. But as the improvements of this eminent mechanician, have not yet been sufficiently tested by time, I forbear to enlarge, as I am satisfied that the public will do ample justice to them. G. Dr. FRANKLIN, who has before been alluded to, is so well known, that any further remarks relative to him would be superfluous. It may not be generally known that General NATHANIEL GREENE, who has been considered as second only to WASHINGTON, in point of talents and military skill, was bred an anchor smith. See Johnson's Life of Greene. ROGER SHERMAN, one of the signers of the declaration of independence, was in early life, a saddler, but by his own industry and application, acquired an education, which enabled him to sus tain many important offices, with honour to himself and benefit to his country. He was a member of the first Congress in 1774, and continued in it for many years. He was a member of the convention which formed our present constitution. He was also a senator in the Congress of the United States.

He rends the oak-and bids it ride, On such social fōrms, our Printers ne'er set up, Cordwainers, when old they are beginning to wax, When they're down, &c. Our Tailors from this jolly board will ne'er sheer off, Down, down, &c. We'll rivet attention to Coppersmiths too, May their steam-boilers ne'er put the folks in a stew :- Derry down, &c. Our Dyers are true men, though much used to lie, When we're down, &c. Our Bookbinders work by the nut and the screw, Where they're down, &c. Our Mastmaker spars not with one brother swigger ;— May our Bakers roll on, and to Charity's meal, (Till their ashes are cold) may they ne'er make ap-peal; And in life's ample trough, may they ne'er need John Doc. Our Painters develop the signs of the time, May they ne'er want a coat, when they're past their best prime: As they can't drink their Easel, as Shakspeare would call it, They'll not brush, while such colours remain for their palette, Which go down, &c. |
