he manufacture of his
pistols. This machinery is usually sold to all parties purchasing the
right to manufacture the revolver. Colonel Colt supplied in this way a
large part of the machinery used in the Government manufactory at
Enfield, in England, and all of that used in the Imperial armory at
Tulin, in Russia. Near the armory, and in the area inclosed by the dike,
Colonel Colt erected a number of tasteful cottages for his workmen, and
warehouses for other kinds of business. His entire expenditure upon his
land and buildings here amounted to more than two million five hundred
thousand dollars.

"Among his other cares, the intellectual and social welfare of his
numerous employes were not forgotten. Few mechanics are favored with as
convenient residences as those he has erected for them; and a public
hall, a library, courses of lectures, concerts, the organization of a
fine band of music, formed entirely from his own workmen, to whom he
presented a superb set of musical instruments, and of a military company
of his operatives, provided by him with a tasteful uniform, and
otherwise treated by him with great liberality, were among the methods
by which he demonstrated his sympathy with the sons of toil."

The Hartford armory is the largest and most complete in the world, in
extent and perfection of machinery. All the articles needed with the
revolver, such as the powder flask, balls, lubricator, bullet molds,
cartridges, etc., are made here on a large scale. The establishment is a
noble monument to the inventive genius and business capacity of its
founder.

In addition to his inventions of fire-arms, Colonel Colt invented a
submarine battery, which was thoroughly tested by the officers of the
United States Navy, and is said to be one of the most formidable engines
for harbor defense ever known. He also invented a submarine telegraph
cable, which he laid and operated with perfect success, in 1843, from
Coney Island and Fire Island to the city of New York, and from the
Merchants Exchange to the mouth of the harbor. His insulating material
consisted of a combination of cotton yarn with asphaltum and beeswax;
the whole was inclosed in a lead pipe. This was one of the most
successful experiments of the early days of submarine telegraphy, and
entitles Colonel Colt to a conspicuous place in the list of those who
brought that science to perfection.

After the permanent establishment of his business, in 1847 and 1848,
