Item, "killer." This is a savage cetacean, probably the same with the "thrasher," about fifteen feet in length, blunt-nosed, strong of jaw, with cruel teeth. On its back is a fin beginning about two thirds the way from tip to tail, running close to the latter, and then sloping away to a point, like the jib of a ship. In the largest this is some five feet long on the back, and eight or ten feet in height,--so large, that, when the creature is swimming on the surface, a strong side-wind will sometimes blow it over. It is a blue-fish on a big scale, or a Semmes in the sea, hungry as famine, fierce as plague, dainty as a Roman epicure, yet omnivorous as time. The seal is its South-Down mutton, the tongue of the whale its venison; for whenever its numbers are sufficient, it will attack this huge cetacean, and torture him till he submits and gives a horrible feast to their greed. Captain Handy had seen thirty or forty of them at this business. They fly with inconceivable fury at their victim, aiming chiefly at the lip, tearing great mouthfuls away, which they instantly reject while darting for another. The bleeding and bellowing monster goes down like a boulder from a cliff, shoots up like a shell from a mortar, beats the sea about him all into crimsoned spray with his tail; but plunge, leap, foam as he may, the finny pirates flesh their teeth in him still, still are fresh in pursuit, until at length, to end one torment by submitting to another, the helpless giant opens his mouth, and permits these sea-devils to devour the quivering morsel they covet. A big morsel; for the tongue of the full-sized right-whale weighs a ton and a half, and yields a ton of oil. The killer is sometimes confounded with the grampus. The latter is considerably larger, has a longer and slenderer jaw, less round at the muzzle, smaller teeth, and "isn't so clean a made fish"; for, in nautical parlance, cetaceans are still fish. Killers frequently try to rob whalers of their prize, and sometimes actually succeed in carrying it down, despite the lances and other weapons with which their attack is so strenuously resisted. Item, cascade. A snowy, broken stripe down a mountain-side; taken to be snow till the ear better informed the eye. Fine; but you need not go there to see. _June 26._--Off to Henley Harbor, sixty-five miles, at the head of the Strait of Belle Isle. Belle Isle itself--sandstone, rich, the Professor said, in ancient fossils--lay in view. The anchor went down in deep water, close beside the notable Castle Island.
