This is a correct sketch of the sea-serpent seen by me while on board the ship Sacramento, on her passage from New York to Melbourne, I being at the wheel at the time. It had the body of a very large snake; its length appeared to me to be about fifty feet or sixty feet. Its head was like an alligator’s, with a pair of flippers about ten feet from its head. The colour was of a reddish brown. At the time seen it was lying perfectly still, with its head raised about three feet above the surface of the sea, and as it got thirty or forty feet astern, it dropped its head.
