A nobler monument of human skill, enterprise, and perseverance, than the invention of cotton-spinning machinery is hardly to be met with; but it must also be owned that its history, encouraging as it is in one aspect, is in another sad and humiliating to the last degree. It is difficult at first to credit the uniform ingratitude and treachery which the various inventors met with from the very men whom their contrivances enriched. "There is nothing," said James Watt in the crisis of his fortunes, worn with care, and sick with hope deferred--"there is nothing so foolish as inventing;" and with far more reason the inventors of cotton-spinning machines could echo the mournful cry. It is sad to think that so proud a chapter of our history should bear so dark a stain. In 1733 the primitive method still prevailed of spinning between the finger and thumb, only one thread at a time; and weaving up the yarn in a loom, the shuttle of which had to be thrown from right to left and left to right by both hands alternately. In that year, however, the first step was made in advance, by the invention of the fly-shuttle, which, by means of a handle and spring, could be jerked from side to side with one hand. This contrivance was due to the ingenuity of John Kay, a loom-maker at Colchester, and proved his ruin. The weavers did their best to prevent the use of the shuttle,--the masters to get it used, and to cheat the inventor out of his reward. Poor Kay was soon brought low in the world by costly law-suits, and being not yet tired of inventing, devised a rude power-loom. In revenge a mob of weavers broke into his house, smashed all his machines, and would have smashed him too, had they laid hands on him. He escaped from their clutches, to find his way to Paris, and to die there in misery not long afterwards. Kay was the first of the martyrs in this branch of invention. James Hargreaves was the next.
