In 1798 Whitney had become deeply impressed with the uncertainty of all his hopes founded upon the cotton-gin, and began to think seriously of devoting himself to some business in which his superior ingenuity, seconded by uncommon industry, would conduct him by a slow but sure road to a competent fortune. It may be considered indicative of solid judgment and a well-balanced mind that he did not, as is so frequently the case with men of inventive genius, become so poisoned with the hopes of vast wealth as to be disqualified for making a reasonable provision for life by the sober earnings of private industry. The enterprise which he selected in accordance with these views was the manufacture of arms for the United States. Through Oliver Wolcott, then Secretary of the Treasury, he obtained a contract for the manufacture of 10,000 stand of arms, 4,000 of which were to be delivered before the last of September of the ensuing year, 1799. Whitney purchased for his works a site called East Rock, near New Haven, now known as Whitneyville, and justly admired for the romantic beauty of its scenery. A water-fall offered the necessary power for the machinery. Here he began operations with great zeal. His machinery was yet to be built, his material collected, and even his workmen to be taught, and that in a business with which he was imperfectly acquainted. A severe winter retarded his operations and rendered him incompetent to fulfil the contract. Only 500 instead of 4,000 stands were delivered the first year, and eight years instead of two were found necessary for completing the whole. During the eight years Whitney was occupied in performing this work, he applied himself to business with the most exemplary diligence, rising every morning as soon as it was day, and at night setting everything in order in all parts of the establishment. His genius impressed itself on every part of the factory, extending even to the most common tools, most of which received some peculiar modification which improved them in accuracy or efficiency. His machines for making the several parts of the musket were made to operate with the greatest possible degree of uniformity and precision. The object at which he aimed, and which he fully accomplished, was to make the same parts of different guns, as the locks, for instance, as much like each other as the successive impressions of a copper-plate engraving, and it has generally been considered that Whitney greatly improved the way of manufacturing arms and laid his country under permanent obligations by augmenting our facilities for national defence. In 1812 he made a contract to manufacture for the United States 15,000 stand of arms, and in the meantime a similar contract with the State of New York. Several other persons made contracts with the Government at about the same time and attempted the manufacture of muskets. The result of their efforts was a complete failure, and in some instances they expended a
