In the seventeenth century, Humphrey Chetham, whose name has already been mentioned as the founder of a splendid charity, was among the eminent tradesmen. The barbarities of the Duke of Alva on the Protestants of the Netherlands, and the revocation of the edict of Nantes, by which the persecutions of the French Protestants was renewed, supplied all our manufacturing districts with skilful Artisans and mechanics in silk and woollen. In 1786, the importation of raw cotton only amounted to nineteen million pounds weight, obtained from the West Indies, the French, Spanish, and Dutch colonies, and from Turkey and Smyrna. Two years previously an American ship which imported eight bags was seized, on the ground that so much cotton could not be the produce of the United States! So early as 1738, one Charles Wyatt, of Birmingham, took out a patent for spinning yarn by machinery, which he tried at Northampton, but reaped no profits from the invention, which was discontinued and forgotten. In 1767, James Hargreaves, an illiterate weaver residing near Church, in Lancashire, who seven years previously had invented a carding machine, much like that in use at the present day, invented the spinning jenny,--by which eighty spindles were set to work instead of the one of the spinning wheel. Hargreaves derived no benefit from his invention; twice a mob of spinners on the old principle rose and destroyed all the machinery made on his plan, and chased him away. In 1769, Richard Arkwright took out his first patent (having Mr. Need of Nottingham and Mr. Strutt of Derby as partners,) for spinning with rollers. Arkwright was born in the humblest class of life at Preston in Lancashire. At "Proud Preston" he first followed the business of a barber, then became a dealer in hair, travelling the country to collect it, and selling it prepared to the wigmakers. Having accumulated a little money, he set about endeavouring to invent perpetual motion, and, in the search, invented, or sufficiently adapted and improved, a cotton spinning apparatus to induce two practical men like the Messrs. Need and Strutt to join him. His claim to original invention has been disputed. That he was not the first inventor is clear, and it is equally clear that he must have been a man of very considerable and original mechanical genius. With Arkwright's patent, the rise of the cotton trade began.
