"Ship _Castilian_, Dec. 12, 1857; N.E. end of St. Helena, distant ten miles. At 6.30 P.M., strong breezes and cloudy, ship sailing about twelve miles per hour. While myself and officers were standing on the leeside of the poop, looking towards the island, we were startled by the sight of a huge marine animal, which reared its head out of the water within twenty yards of the ship, when it suddenly disappeared for about half a minute, and then made its appearance in the same manner again, showing us distinctly its neck and head about ten or twelve feet out of the water. Its head was shaped like a long nun-buoy, and I suppose the diameter to have been seven or eight feet in the largest part, with a kind of scroll, or tuft of loose skin, encircling it about two feet from the top; the water was discoloured for several hundred feet from its head, so much so that, on its first appearance, my impression was that the ship was in broken water, produced, as I supposed, by some volcanic agency since the last time I had passed the island; but the second appearance completely dispelled those fears, and assured us that it was a monster of extraordinary length, which appeared to be moving slowly towards the land. The ship was going too fast to enable us to reach the masthead in time to form a correct estimate of its extreme length; but from what we saw from the deck, we conclude that it must have been over two hundred feet long. The boatswain and several of the crew who observed it from the topgallant forecastle, state that it was more than double the length of the ship, in which case it must have been five hundred feet. Be that as it may, I am convinced that it belonged to the serpent tribe; it was of a dark colour about the head, and was covered with several white spots."
