One thing is very evident. Mr. Pike does not dream that the murderer of Captain Somers is on board the Elsinore. He has never glimpsed that prodigious fissure that clefts Mr. Mellaire’s, or, rather, Sidney Waltham’s, skull. And I, for one, shall never tell Mr. Pike. And I know, now, why from the very first I disliked the second mate. And I understand that live thing, that other thing, that lurks within and peers out through the eyes. I have recognized the same thing in the three gangsters for’ard. Like the second mate, they are prison birds. The restraint, the secrecy, and iron control of prison life has developed in all of them terrible other selves.

Yes, and another thing is very evident. On board this ship, driving now through the South Atlantic for the winter passage of Cape Horn, are all the elements of sea tragedy and horror. We are freighted with human dynamite that is liable at any moment to blow our tiny floating world to fragments.

CHAPTER XXV.

The days slip by. The south-east trade is brisk and small splashes of sea occasionally invade my open ports. Mr. Pike’s room was soaked yesterday. This is the most exciting thing that has happened for some time. The gangsters rule in the forecastle. Larry and Shorty have had a harmless fight. The hooks continue to burn in Mulligan Jacobs’s brain. Charles Davis resides alone in his little steel room, coming out only to get his food from the galley. Miss West plays and sings, doctors Possum, launders, and is forever otherwise busy with her fancy work. Mr. Pike runs the phonograph every other evening in the second dog-watch. Mr. Mellaire hides the cleft in his head. I keep his secret. And Captain West, more remote than ever, sits in the draught of wind in the twilight cabin.

We are now thirty-seven days at sea, in which time, until to-day, we have not sighted a vessel. And to-day, at one time, no less than six vessels were visible from the deck. Not until I saw these ships was I able thoroughly to realize how lonely this ocean is.

Mr. Pike tells me we are several hundred miles off the South American coast. And yet, only the other day, it seems, we were scarcely more distant from Africa. A big velvety moth fluttered aboard this morning, and we are filled with conjecture. How possibly could it have come from the South American coast these hundreds of miles in the teeth of the trades?

The Southern Cross has been visible, of course, for weeks; the North Star has disappeared behind the bulge of the earth; and the Great Bear, at its highest, is very low. Soon it, too, will be gone and we shall be raising the Magellan Clouds.

I remember the fight between Larry and Shorty. Wada reports that Mr. Pike watched it for some time, until, becoming incensed at their awkwardness, he clouted both of them with his open hands and made them stop, announcing that until they could make a better showing he intended doing all the fighting on the Elsinore himself.

It is a feat beyond me to realize that he is sixty-nine years old. And when I look at the tremendous build of him and at his fearful, man-handling hands, I conjure up a vision of him avenging Captain Somers’s murder.

Life is cruel. Amongst the Elsinore’s five thousand tons of coal are thousands of rats. There is no way for them to get out of their steel-walled prison, for all the ventilators are guarded with stout wire-mesh. On her previous voyage, loaded with barley, they increased and multiplied. Now they are imprisoned in the coal, and cannibalism is what must occur among them. Mr. Pike says that when we reach Seattle there will be a dozen or a score of survivors, huge fellows, the strongest and fiercest. Sometimes, passing the mouth of one ventilator that is in the after wall of the chart-house, I can hear their plaintive squealing and crying from far beneath in the coal.
