“Never mind what Lecky says,” interrupts my literal mind. “Let me tell you what the Nautical Almanac says. The Nautical Almanac says that to-day, June 7, the sun was 1 minute and 26 seconds behind time and catching up at the rate of 14.67 seconds per hour. It says that yesterday, June 6, the sun was 1 minute and 36 seconds behind time and catching up at the rate of 15.66 seconds per hour. You see, it is preposterous to think of correcting to-day’s sun by yesterday’s time-table.” My heart almost stood still waiting the answer. By that answer my professional medical prestige stood or fell. Martin, I could see, was quite sure it was going to fall. And then the answer—O blessed answer!!

The Snark was lying at anchor at Raiatea, just off the village of Uturoa. She had arrived the night before, after dark, and we were preparing to pay our first visit ashore. Early in the morning I had noticed a tiny outrigger canoe, with an impossible spritsail, skimming the surface of the lagoon. The canoe itself was coffin-shaped, a mere dugout, fourteen feet long, a scant twelve inches wide, and maybe twenty-four inches deep. It had no lines, except in so far that it was sharp at both ends. Its sides were perpendicular. Shorn of the outrigger, it would have capsized of itself inside a tenth of a second. It was the outrigger that kept it right side up. I saw an illustration of the thorough trial given the suspect, when I visited Kalihi with Mr. Pinkham, president of the Board of Health. The suspect was an Hawaiian, seventy years of age, who for thirty-four years had worked in Honolulu as a pressman in a printing office. The bacteriologist had decided that he was a leper, the Examining Board had been unable to make up its mind, and that day all had come out to Kalihi to make another examination.

So we took heart and went at it again. The ruined engine was lashed down on its rotten foundation; the smashed castings and cogs of the power transmission were taken down and stored away—all for the purpose of taking them to Honolulu where repairs and new castings could be made. Somewhere in the dim past the Snark had received on the outside one coat of white paint. The intention of the colour was still evident, however, when one got it in the right light. The Snark had never received any paint on the inside. On the contrary, she was coated inches thick with the grease and tobacco-juice of the multitudinous mechanics who had toiled upon her. Never mind, we said; the grease and filth could be planed off, and later, when we fetched Honolulu, the Snark could be painted at the same time as she was being rebuilt. 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. 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.
