And now to the particular physics of surf-riding. Get out on a flat board, six feet long, two feet wide, and roughly oval in shape. Lie down upon it like a small boy on a coaster and paddle with your hands out to deep water, where the waves begin to crest. Lie out there quietly on the board. Sea after sea breaks before, behind, and under and over you, and rushes in to shore, leaving you behind. When a wave crests, it gets steeper. Imagine yourself, on your hoard, on the face of that steep slope. If it stood still, you would slide down just as a boy slides down a hill on his coaster. “But,” you object, “the wave doesn’t stand still.” Very true, but the water composing the wave stands still, and there you have the secret. If ever you start sliding down the face of that wave, you’ll keep on sliding and you’ll never reach the bottom. Please don’t laugh. The face of that wave may be only six feet, yet you can slide down it a quarter of a mile, or half a mile, and not reach the bottom. For, see, since a wave is only a communicated agitation or impetus, and since the water that composes a wave is changing every instant, new water is rising into the wave as fast as the wave travels. You slide down this new water, and yet remain in your old position on the wave, sliding down the still newer water that is rising and forming the wave. You slide precisely as fast as the wave travels. If it travels fifteen miles an hour, you slide fifteen miles an hour. Between you and shore stretches a quarter of mile of water. As the wave travels, this water obligingly heaps itself into the wave, gravity does the rest, and down you go, sliding the whole length of it. If you still cherish the notion, while sliding, that the water is moving with you, thrust your arms into it and attempt to paddle; you will find that you have to be remarkably quick to get a stroke, for that water is dropping astern just as fast as you are rushing ahead. The Snark has been a hospital for months, and I confess that we are getting used to it. At Meringe Lagoon, where we careened and cleaned the Snark’s copper, there were times when only one man of us was able to go into the water, while the three white men on the plantation ashore were all down with fever. At the moment of writing this we are lost at sea somewhere northeast of Ysabel and trying vainly to find Lord Howe Island, which is an atoll that cannot be sighted unless one is on top of it. The chronometer has gone wrong. The sun does not shine anyway, nor can I get a star observation at night, and we have had nothing but squalls and rain for days and days. The cook is gone. Nakata, who has been trying to be both cook and cabin boy, is down on his back with fever. Martin is just up from fever, and going down again. Charmian, whose fever has become periodical, is looking up in her date book to find when the next attack will be. Henry has begun to eat quinine in an expectant mood. And, since my attacks hit me with the suddenness of bludgeon-blows I do not know from moment to moment when I shall be brought down. By a mistake we gave our last flour away to some white men who did not have any flour. We don’t know when we’ll make land. Our Solomon sores are worse than ever, and more numerous. The corrosive sublimate was accidentally left ashore at Penduffryn; the peroxide of hydrogen is exhausted; and I am experimenting with boracic acid, lysol, and antiphlogystine. At any rate, if I fail in becoming a reputable M.D., it won’t be from lack of practice.!

Rather did “I waken to the voiceless dark,” and listen to the creaking of the bulkheads and the rippling of the sea alongside as the Snark logged steadily her six knots an hour. I went over my calculations again and again, striving to find some mistake, until my brain was in such fever that it discovered dozens of mistakes. Suppose, instead of being sixty miles off Futuna, that my navigation was all wrong and that I was only six miles off? In which case my course would be wrong, too, and for all I knew the Snark might be running straight at Futuna. For all I knew the Snark might strike Futuna the next moment. I almost sprang from the bunk at that thought; and, though I restrained myself, I know that I lay for a moment, nervous and tense, waiting for the shock. Another volunteer I could never have accepted was the finicky young fellow who, to show me how necessary it was that I should give him a chance, pointed out that “to go in the ordinary boat, be it schooner or steamer, would be impracticable, for I would have to mix among and live with the ordinary type of seamen, which as a rule is not a clean sort of life.”

Glen Ellen, California, Wada and Henry, however, were tougher patients with which to deal. In the first place, Wada got in a bad funk. He was of the firm conviction that his star had set and that the Solomons would receive his bones. He saw that life about him was cheap. At Penduffryn he saw the ravages of dysentery, and, unfortunately for him, he saw one victim carried out on a strip of galvanized sheet-iron and dumped without coffin or funeral into a hole in the ground. Everybody had fever, everybody had dysentery, everybody had everything. Death was common. Here to-day and gone to-morrow—and Wada forgot all about to-day and made up his mind that to-morrow had come. “But has any man ever succeeded in doing it?”
