It would be difficult to find anything in the literature of mechanical invention more naively picturesque than this Quaker, passed through furnaces of two revolutions, trying to humanize gunpowder. Here is a substance with maximum of power and minimum of bulk and weight.
"When I consider the wisdom of nature I must think that she endowed matter with this extraordinary property for other purposes than that of destruction. Poisons are capable of other uses than that of killing. If the power which an ounce of gunpowder contains could be detailed out as steam or water can be it would be a most commodious natural power."
Having failed to convert revolutions to Quakerism, Paine tries to soften the heart of gunpowder itself, and insists that its explosiveness may be restrained and detailed like strokes on a boy's top to obtain continual motion. The sleeping top, the chastened repose of perfect motion, like the quiet of the spinning worlds, is the Quaker inventor's ideal, and he begs the President of the United States to try the effect of the smallest pistol made--the size of a quill--on a wheel with peripheral cups to receive the discharges.
* I am reluctantly compelled to give only the main ideas of several theses of this kind by Paine, found among Jefferson's papers. The portion of the "Jefferson Papers" at Washington written by Paine would fill a good volume.
"The biographers of Paine," wrote his friend, Joel Barlow, "should not forget his mathematical acquirements and his mechanical genius." But it would require a staff of specialists, and a large volume, to deal with Paine's scientific studies and contrivances--with his planing machine, his new crane, his smokeless candle, his wheel of concentric rim, his scheme for using gunpowder as a motor, above all his iron bridge. As for the bridge, Paine feels that it is a sort of American revolution carried into mechanics; his eagle cannot help spreading a little in the wondering eyes of the Old World. "Great scenes inspire great ideas," he writes to Sir George Staunton.
"The natural mightiness of America expands the mind, and it partakes of the greatness it contemplates. Even the war, with all its evils, had some advantages. It energized invention and lessened the catalogue of impossibilities. At the conclusion of it every man returned to his home to repair the ravages it had occasioned, and to think of war no more. As one amongst thousands who had borne a share in that memorable revolution, I returned with them to the re-enjoyment of quiet life, and, that I might not be idle, undertook to construct a single arch for this river [Schuylkill]. Our beloved General had engaged in rendering another river, the Potowmac, navigable. The quantity of iron I had allowed in my plan for this arch was five hundred and twenty tons, to be distributed into thirteen ribs, in commemoration of the Thirteen United States."
