The Niagara, one of the finest screw frigates in the navy, and which, with the Colorado, is now repairing, is noted for being connected with the Atlantic cable expedition, as well as for conveying the Japanese embassy home. She is the pet of the navy, and great credit is due the late George Steers for such a splendid specimen of naval architecture. The Powhattan, Minnesota, and Mississippi are attached to the South Atlantic Squadron; the San Jacinto to the East Gulf Squadron; the Susquehanna to the West Gulf Squadron, and the Saranac to the Pacific Squadron. The old Princeton is the receiving ship at Philadelphia. Of these steam frigates, six are screw, and three sidewheel.
