The course of my narrative now requires a brief account of my mother's only brother, whose example and conversation, more than anything else, taught me to turn my thoughts westwards, and finally to follow his example by crossing the Atlantic ocean, and seeking "fresh fields and pastures new" under a transatlantic sky. John Isaac Hawkins was a name well known, both in European and American scientific circles, fifty years ago, as an inventor of the most fertile resource, and an expert in all matters relating to civil engineering. He must have left England for America somewhere about the year 1790, full of republican enthusiasm and of schemes of universal benevolence. Of his record in the United States I know very little, except that he married a wife in New Jersey, that he resided at Bordenton, that he acquired some property adjacent to Philadelphia, that he was intimate with the elder Adams, Jefferson, and many other eminent men. Returning with his wife to England, after twenty-five years' absence, he established a sugar refinery in Titchfield Street, Cavendish square, London, patronized his English relatives with much condescension, and won my childish heart by great lumps of rock-candy, and scientific experiments of a delightfully awful character. Also, he borrowed my mother's money, to be expended for the good of mankind, and the elaboration of the teeming offspring of his inexhaustible inventive faculty. Morden's patent lead pencils, Bramah's patent locks, and, I think, Gillott's steel pens were among his numerous useful achievements, from some or all of which he enjoyed to the day of his death a small income, in the shape of a royalty on the profits. He assisted in the perfecting of Perkins's steam-gun, which the Duke of Wellington condemned as too barbarous for civilized warfare, but which its discoverer, Mr. Perkins, looked upon as the destined extirpator of all warfare, by the simple process of rendering resistance utterly impossible. This appalling and destructive weapon has culminated in these times in the famous mitrailleuses of Napoleon III, at Woerth and Sedan, which, however, certainly neither exterminated the Prussians nor added glory to the French empire.
