Joseph P. Bradley Roberts v. United States (92 U.S. 41…

In pursuance of this act, on the 20th of April, 1847, a contract was made by the Navy Department with Sloo, whereby he agreed to build five naval steamships, capable of being converted to the purposes of naval warfare, of which four were to be not less than fifteen hundred tons burden, and one to be not less than six hundred.
