The lion that has once eaten a man has ever after, it is said, a wild craving after human blood. And it would seem that the faculty of invention, once aroused, its appetite for exercise is constant and insatiable. Cartwright having discovered his dormant powers, could no more cease to use them than to eat. A return to his quiet literary ways, fond as he still was of such pursuits, was impossible. An inventor he was, and an inventor he must continue till his eye was glazed, and his brain numbed in death. When a clergyman he set himself to study medicine, and acquired great skill and knowledge in the science, solely for the benefit of the poor parishioners, and now he gave himself up to the labours of invention with the same benevolent motives. Gain had not tempted him to enter the arena,--discouragement and ruin were not to drive him from it. The resources of his ingenuity seemed inexhaustible, and there was no limit to its range of objects. Wool-combing machines, bread and biscuit baking machines, rope-making machines, ploughs, and wheel carriages, fire-preventatives, were in turn invented or improved by him. He predicted the use of steam-ships, and steam-carriages,--and himself devised a model of the former (with clock-work instead of a steam-engine), which a little boy used to play with on the ponds at Woburn, that was to grow up into an eminent statesman--Lord John Russell. To the very last hour of his life his brain was teeming with new designs. He went down to Dover in his eightieth year for warm sea-bathing, and suggested to his bathman a way of pumping up the water that saved him the wages of two men; and almost the day before his death, he wrote an elaborate statement of a new mode he had discovered of working the steam-engine. Moved by an irresistible impulse to promote the "public weal," he truly fulfilled the resolution he expressed in verse,-- "With mind unwearied, still will I engage, In spite of failing vigour and of age, Nor quit the combat till I quit the stage." In 1808 he was rewarded by Parliament for his invention of the power-loom, and the losses it brought upon him, by a grant of L10,000. He died in October 1823. V.--SIR ROBERT PEEL.
