he did not lose sight of his great idea, the Caloric-Engine. All his
spare hours and spare funds were devoted to experiments with the view
of overcoming the practical difficulties which stood in the way of its
success. Towards the end of the year 1851 he seemed to be on the point
of realizing his hopes, having constructed a large stationary engine,
which was applied with great success, at the Phoenix Foundry in New
York, to the actual work of pumping water. Soon after, through the
liberality of Mr. John B. Kitching, a well-known merchant of New
York, he was enabled to test the invention on a magnificent scale. A
ship of two thousand tons, propelled by the power of caloric-engines,
was planned and constructed by him in the short space of seven months,
and in honor of the inventor received the name of the "Ericsson."

Every one will remember the interest which this caloric-ship excited
throughout the country. She made a trip from New York to Alexandria on
the Potomac, in very rough weather, in the latter part of February,
1853. On this trip the engines were in operation for seventy-three
hours without being stopped for a moment, and without requiring the
slightest adjustment, the consumption of fuel being only five tons in
twenty-four hours. At Alexandria she was visited by the President and
President elect, the heads of the departments, a large number of naval
officers, and many members of both Houses of Congress, and
subsequently by the foreign ministers in a body, and by the Legislature
of Virginia, then in session. Ericsson was invited by a committee of
the Legislature to visit Richmond, as the guest of the State. The
Secretary of the Navy recommended, in a special communication to
Congress, the passage of a resolution authorizing him to contract for
the construction of a frigate of two thousand tons to be equipped with
caloric-engines, and to appropriate for this purpose five hundred
thousand dollars. This recommendation failed in consequence of the
