One of the first grand results of Watt’s invention,—which placed an almost unlimited power at the command of the producing classes,—was the establishment of the cotton-manufacture. The person most closely identified with the foundation of this great branch of industry was unquestionably Sir Richard Arkwright, whose practical energy and sagacity were perhaps even more remarkable than his mechanical inventiveness. His originality as an inventor has indeed been called in question, like that of Watt and Stephenson. Arkwright probably stood in the same relation to the spinning-machine that Watt did to the steam-engine and Stephenson to the locomotive. He gathered together the scattered threads of ingenuity which already existed, and wove them, after his own design, into a new and original fabric. Though Lewis Paul, of Birmingham, patented the invention of spinning by rollers thirty years before Arkwright, the machines constructed by him were so imperfect in their details, that they could not be profitably worked, and the invention was practically a failure. Another obscure mechanic, a reed-maker of Leigh, named Thomas Highs, is also said to have invented the water-frame and spinning-jenny; but they, too, proved unsuccessful. When the demands of industry are found to press upon the resources of inventors, the same idea is usually found floating about in many minds;—such has been the case with the steam-engine, the safety-lamp, the electric telegraph, and other inventions. Many ingenious minds are found labouring in the throes of invention, until at length the master mind, the strong practical man, steps forward, and straightway delivers them of their idea, applies the principle successfully, and the thing is done. Then there is a loud outcry among all the smaller contrivers, who see themselves distanced in the race; and hence men such as Watt, Stephenson, and Arkwright, have usually to defend their reputation and their rights as practical and successful inventors.
