On the 1st of May, 1855, was launched the steam-propeller Arctic, built originally for a lightboat, she was afterward altered and strengthened to fit her for the celebrated Polar Expedition under Dr. Kane, the history of which expedition is no doubt familiar to all our readers; since her return from that expedition she has been used as a light-ship. On the 11th of October of the same

year another light-boat, called the Martia's Indestry, was launched at the Yard, and on the 24th of the same month the screw-propeller Wi was launched; attached first (1857-58) to te Home squadron as the flag-ship of Commcd re Hiram Paulding, afterward (1859-60) the £ship of flag-officer E.

On the 20th of October, 1858, the screw-pr peller Lancaster, 22 guns, was launched. The launching of this fine vessel was an event wh excited considerable public interest and curiosity, drawing a large number of persons from the homes to witness it; Miss Harriet Lane, wdispensed the hospitalities of the White House during the administration of James Buchanan, performed the christening. From 1862 to 1866 the vessel was attached to the Pacific squadron, under Commodore Henry K. Hoff and Joseph Lantan, and Acting Rear-Admirals Charles H. Bell and George F. Pearson; returning from that station to Norfolk in 1867; remained at Norfolk undergone repairs until 1869. From 1870 to 1873, attached to South Atlantic squadron as the flag-ship respentively of Rear-Admirals Joseph Lanman and Wiliam R.

North Atlantic, Commander, F. H. Baker; now laid up at Washington Navy Yard.

Screw-propeller Pawnee, 11 guns, launched Or tober 8th, 1859. tober 8th, 1859. This vessel was built for te government by Mr. John M. Griffith, a private constructor; owing to certain peculiarities in her construction, it led to much criticism both adverse

and favorable among nautical men hereabout. She certainly has attained historic celebrity by being the Fire Bug that kindled a flame which startled the good people of Norfolk and Portsmouth. Entering Gosport harbor on the night of April 20th, 1861, the citizens did not expect nor were they prepared for her arrival; thinking she had come along with the Cumberland and Pennsylvania for the purpose of bombarding the town, as a matter of retaliation, because they had on the previous night rifled the United States magazine of about 4,000 kegs of powder. Her coming was not unexpected, however, by the several hundred men on the vessels mentioned, and they greeted her arrival with a volley of cheers. The Commodore, G. J. Pendergrast, ordered the marines. from the vessels and in the Yard to commence the work of destruction. All the books, papers and valuable archives of the Yard were transferred to the Pawnee, and by 4 o'clock on Sunday morning she passed out of the harbor with the Cumberland in tow, every soul from the other ships and from the Navy Yard, save two, were aboard of the two vessels. Just as they left their moorings a rocket was sent up from the deck of the Pawnee; at that instant the ship-houses and the old New York, a ship that had been thirty years on the stocks; the Pennsylvania, Merrimac, Germantown, Plymouth, Raritan, Columbia and Dolphin, all shot forth great tongues of fire that lit up both sea and heaven with a lurid glare, joining both as though they were one undivided molten lake. The scene was terribly grand; and so in truth it should have been, for was it not the most expensive exhibition of fireworks ever attempted by Uncle Sam ? But whilst admiring the grandeur of that destructive scene, the heart of each and every loyal man standing upon the decks of those departing vessels felt a deep pang of sorrow, as one after another of those gallant ships went swiftly down to their oozy beds. 1862-65 the Pawnee was attached to the South Atlantic squadron; 1866, repairing at Portsmouth, New Hampshire; 1867-69, South Atlantic; 1870, at Norfolk, in ordinary; 1871-73, North Atlantic squadron, and since that time employed as a store ship.
