"Mr. Arkwright, after many years intense and painful application, invented, about the year 1768, his present method of spinning cotton, but upon very different principles from any invention that had gone before it. He was himself a native of ; but having so recently witnessed the ungenerous treatment of poor Hargrave, by the people of that county, he retired to , and obtained a patent in the year 1769, for making cotton, flax, and wool into yarn. But, after some experience, finding that the common method of preparing the materials for spinning (which is essentially necessary to the perfection of good yarn) was very imperfect, tedious, and expensive, he turned his thoughts towards the construction of engines for that purpose; and, in the pursuit, spent several years of intense study and labour, and at last produced an invention for carding and preparing the materials, founded in some measure on the principles of his first machine. These inventions, united, completed his great original plan. But his last machines being very complicated, and containing some things materially different in their construction, and some others materially different in their use, from the inventions for which his first patent was obtained, be procured a patent for these also in December, 1775."
