The Age of Invention [15]
produces six to eight billion pounds of cotton annually, and ninety-nine per cent of this is the upland or green-seed cotton, which is cleaned on the Whitney type of gin and was first made commercially available by Whitney's invention.*

More than half of this enormous crop is still exported in spite of the great demand at home. Cotton became and has continued to be the greatest single export of the United States. In ordinary years its value is greater than the combined value of the three next largest exports. It is on cotton that the United States has depended for the payment of its trade balance to Europe.
Other momentous results followed on the invention of the cotton gin. In 1793 slavery seemed a dying institution, North and South. Conditions of soil and climate made slavery unprofitable in the North. On many of the indigo, rice, and tobacco plantations in the South there were more slaves than could be profitably employed, and many planters were thinking of emancipating their slaves, when along came this simple but wonderful machine and with it the vision of great riches in cotton; for while slaves could not earn their keep separating the cotton from its seeds by hand, they could earn enormous profits in the fields, once the difficulty of extracting the seeds was solved. Slaves were no longer a liability but an asset. The price of "field hands" rose, and continued to rise. If the worn-out lands of the seaboard no longer afforded opportunity for profitable employment, the rich new lands of the Southwest called for laborers, and yet more laborers. Taking slaves with them, younger sons pushed out into the wilderness, became possessed of great tracts of fertile land, and built up larger plantations than those upon which they had been born. Cotton became King of the South.
The supposed economic necessity of slave labor led great men to defend slavery, and politics in the South became largely the defense of slavery against the aggression, real or fancied, of the free North. The rift between the sections became a chasm. Then came the War of Secession.
Though Miller was dead, Whitney carried on the fight for his rights in Georgia. His difficulties were increased by a patent which the Government at Philadelphia issued in May, 1796, to Hogden Holmes, a mechanic of Augusta, for an improvement in the cotton gin. The Holmes machines were soon in common use, and it was against the users of these that many of the suits for infringement were brought. Suit after suit ran its course in the Georgia courts, without a single decision in the inventor's favor. At length, however, in December, 1806, the validity of Whitney's patent was finally determined by decision of the United States Circuit Court in Georgia. Whitney asked for a perpetual injunction against the Holmes machine, and the court, finding that his invention was basic, granted him all that he asked.
By this time, however, the life of the patent had nearly run its course. Whitney applied to Congress for a renewal, but, in spite of all his arguments and a favorable committee report, the opposition from the cotton States proved too strong, and his application was denied. Whitney now had other interests. He was a great manufacturer of firearms, at New Haven, and as such we shall meet him again in a later chapter.
CHAPTER III. STEAM IN CAPTIVITY
For the beginnings of the enslavement of steam, that mighty giant whose work has changed the world we live in, we must return to the times of Benjamin Franklin. James Watt, the accredited father of the modern steam engine, was a contemporary of Franklin, and his engine was twenty-one years old when Franklin died. The discovery that steam could be harnessed and made to work is not, of course, credited to James Watt. The precise origin of that discovery is unknown. The ancient Greeks had steam engines of a sort, and steam engines of another sort were pumping water out of mines in England when James Watt was born. James Watt, however, invented and applied the
