Since these “appearances” on the American side have taken place, we have had many accounts of the greatest of all the “marines.” It has been frequently seen in the Atlantic, once or twice in the South Sea—sometimes computed at three hundred feet, sometimes at seventy—sometimes with a beard, sometimes without. The last account of it is taken from the log-book of the “Jesse Gleaner,” in which it is depicted as resembling in the head, a “griffin;” in the body, a hundred sugar hogs-_heads_ linked together by a rope; and in the tail, as one of Peter Parley’s best. Whether my young friends will ever hear or know more of it, will be left to the future concatenation of events. Perhaps “Old Charley” may pick it up in the Baltic, or Keet lay hold of it at the “fish ordinary” at Billingsgate. * * * * * Since the above was written, we have received the following, concerning the capture of the “beast.” It is in a letter from Charles Seabury, master of the whale ship “Monongatiela,” of New Bedford, and states as follows,—On the morning of the 13th of January, when in latitude 3 deg. 10 min. S., and longitude 131 deg. 50 min. W., the man on the look-out cried “white water.” I was aloft half-an-hour before I observed anything like white water—then I presumed it was a shoal of porpoises. I ordered the mate to keep both eyes open, and went down, it being my breakfast hour. Before I reached the deck, my attention was called to the sudden cry of Annetu Vanjan, a Marquesan Islander. “Oh look! me see! too much! no whale! too big! me ’fraid!” The native continued to look with eagerness. I turned to leeward, and my eye rested on the strangest creature I had ever seen in the ocean. I knew it was not a whale. “It is a Sea Serpent!”—I exclaimed; “stand by the boats.” When they had mustered, I said, “I do not order you to go into the boats—who will volunteer?” Every American in the ship stepped out—we lowered—I told the boat-steerer, James Whittermore, of Vermont, to stand up, who, with calm intrepidity, laid hold of his harpoon; when I beckoned with my hand, quick as thought both his weapons were buried to the socket in the repulsive body before us; the head and tail of the monster rushed to touch the wound; the frightfulness of the head filled the crew with terror; he began to sound, and the line went out, in all, one thousand fathoms. At four a.m., on the 14th inst., sixteen hours after it went down, the line began to slack, and just before breakfast it rose; we lanced the body repeatedly without any signs of life; at last it drew itself up, and we pulled away, and then witnessed the terrific dying struggles of the monster. The evolutions of the body were quick as lightning, like the revolving of a thousand enormous black wheels, and a sound was heard, so dead and unearthly, that a thrill of horror ran through our veins. The convulsive effort lasted fifteen minutes, when suddenly it ceased, turned up, and lay still. Our prey was dead!
