PHILADELPHIA NAVY-YARD.

Our engraving presents a view of the Navy-Yard, taken from a point of view below the city of Philadelphia. From this yard have come some of the best sailing and steam-vessels that have ever been built for Uncle Sam. The largest vessel that ever floated upon our waters, “The Pennsylvania,” was built here. She is useless, and is most scandalously given over—we believe, as a sort of “receiving ship,” and is rotting ingloriously. She should have been sent to the “World’s Fair” by Congress, filled with American products, and the Arts of Peace. But Congress was busy—talking about the “dissolution of the Union”—Pshaw!—and had no time for national business.
