“But what would be the result if I kept the whole present?” I asked. Even in the little we did learn there were slips that accounted for the apparently antic behaviour of the Snark. On Thursday, May 16, for instance, the trade wind failed us. During the twenty-four hours that ended Friday at noon, by dead reckoning we had not sailed twenty miles.!

“Yes, every last fish,” Allicot answered. “You see, when the surround is completed, you, being the guest of honour, must take a harpoon and impale the first one. It is the custom. Then everybody goes in with their hands and throws the catch out on the sand. There will be a mountain of them. Then one of the chiefs will make a speech in which he presents you with the whole kit and boodle. But you don’t have to take them all. You get up and make a speech, selecting what fish you want for yourself and presenting all the rest back again. Then everybody says you are very generous.” Finally he arrived, sitting bold upright on a branch which could be screwed into a mahogany pedestal, with his foot in the air, his head on one side, and in his beak a nut which the naturalist, from love of the sumptuous, had gilded. She put him in her room.

He had died. The letter told nothing more. CHAPTER XV CRUISING IN THE SOLOMONS 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.
