_To the Senate and House of Representatives of the United States_:
I transmit herewith a letter from the Secretary of the Navy, containing
one from Captain John Rodgers, president of the Naval Board, accompanied
by a description of the inclined plane, dock, and fixtures for hauling
up ships, and an estimate of the cost and materials and workmanship
necessary for the completion of a dock and wharves, proposed to be
connected with the inclined plane constructed at the navy-yard,
Washington, and recommend the same to the attentive consideration of
Congress.
It is confidently believed that this invention combines advantages so
highly useful as to justify the appropriation required.
