ier than this (in 1807), Abraham Bloodgood, of Albany, suggested the construction of a floating revolving battery not unlike, in its essential character, the revolving turret built by Captain Ericsson in the winter of 1861-62.
In March, 1814, Thomas Gregg, of Pennsylvania, obtained a patent for a proposed ironclad steam vessel-of-war, resembling in figure the gunboats and rams used during the Civil War.

Gregg's United States patent, March, 1814, was an iron-clad bomb-proof steam vessel, and will be noticed presently.
The fiubject received very early attention in this country, and as early as March, 1814, a Ball-proof vessel was patented by Thomas Gregg, of Fayette Co., Pennsylvania.
The design embraced a flat upper deck, from which the sides and ends sloped outwardly on was proposed as a covering for the exposed portion.
It does not appear that a vessel was ever actually constructed on Gregg's plan, but the invention is interesting as embodying some of the features which were afterwards adopted by both North an as a motive-power for vessels, it was proposed to employ it as a means of propulsion for iron-clad floating batteries.

In 1842 the late R. L. Stevens commenced at New York the construction of an iron-clad warvessel,
