Yesterday morning, about 7 o'clock, four more steamers entered the harbor, with 3,000 troops on board.
They are principally from New York.

When Governor Sprague's regiment from Rhode Island left for Washington, three negro men, belonging to the Hon. Geo. W. Hughes, residing some ten miles from this city, attempted to follow them and escape.
As soon as the Governor, who was in command, was apprised of the fact he had them arrested and conveyed to their master.

Yesterday the troops ran one of the engines off the track from the railroad, precipitating it down an eighteen-feet bank a few miles from the Junction.
