Some time before abandoning the manufacture of the cotton gin, Mr. Whitney established an arms factory in New Haven, and obtained a contract from the Government for ten thousand stand of arms, to be delivered in two years. At this time he not only had to manufacture the machinery needed by him for this purpose, but had to invent the greater part of it. This delayed the execution of his contract for eight years, but at the expiration of that time he had so far perfected his establishment, which had been removed to Whitneyville, Conn., that he at once entered into contracts for thirty thousand more arms, which he delivered promptly at the appointed time. His factory was the most complete in the country, and was fitted up in a great measure with the machinery which he had invented, and without which the improved weapons could not be fabricated. He introduced a new system into the manufacture of fire-arms, and one which greatly increased the rapidity of construction. "He was the first manufacturer of fire-arms who carried the division of labor to the extent of leaking it the duty of each workman to perform by machinery but one or two operations on a single portion of the gun, and thus rendered all the parts adapted to any one of the thousands of arms in process of manufacture at the same time." His success was now marked and rapid. His factory was taxed to its fullest capacity to supply the demand for arms. His genius was rewarded at last, and he acquired a fortune which enabled him not only to pass the evening of his days in comfort, but also to leave a handsome estate to his family. He married a daughter of Judge Pierpont Edwards, a lady of fine accomplishments and high character. He died at New Haven on the 8th of January, 1825, in his sixtieth year. CHAPTER XVI.
