Once even, she had said: The world faded as the procession of the weeks marched by. The world faded until at last there ceased to be any world except the little world of the Snark, freighted with her seven souls and floating on the expanse of the waters. Our memories of the world, the great world, became like dreams of former lives we had lived somewhere before we came to be born on the Snark. After we had been out of fresh vegetables for some time, we mentioned such things in much the same way I have heard my father mention the vanished apples of his boyhood. Man is a creature of habit, and we on the Snark had got the habit of the Snark. Everything about her and aboard her was as a matter of course, and anything different would have been an irritation and an offence.!

With my surgical instruments it is different. While I have not yet had serious use for them, I do not regret the space they occupy. The thought of them makes me feel good. They are so much life insurance, only, fairer than that last grim game, one is not supposed to die in order to win. Of course, I don’t know how to use them, and what I don’t know about surgery would set up a dozen quacks in prosperous practice. But needs must when the devil drives, and we of the Snark have no warning when the devil may take it into his head to drive, ay, even a thousand miles from land and twenty days from the nearest port. When we increased the length of the Snark in order to get space for a bath-room, we found that all the space was not required by the bath-room. Because of this, we increased the size of the engine. Seventy horse-power our engine is, and since we expect it to drive us along at a nine-knot clip, we do not know the name of a river with a current swift enough to defy us.

The Australian specialists agreed that the malady was non-parasitic, and that, therefore, it must be nervous. It did not mend, and it was impossible for me to continue the voyage. The only way I could have continued it would have been by being lashed in my bunk, for in my helpless condition, unable to clutch with my hands, I could not have moved about on a small rolling boat. Also, I said to myself that while there were many boats and many voyages, I had but one pair of hands and one set of toe-nails. Still further, I reasoned that in my own climate of California I had always maintained a stable nervous equilibrium. So back I came. The Snark is to be sailed. There will be a gasolene engine on board, but it will be used only in case of emergency, such as in bad water among reefs and shoals, where a sudden calm in a swift current leaves a sailing-boat helpless. The rig of the Snark is to be what is called the “ketch.” The ketch rig is a compromise between the yawl and the schooner. Of late years the yawl rig has proved the best for cruising. The ketch retains the cruising virtues of the yawl, and in addition manages to embrace a few of the sailing virtues of the schooner. The foregoing must be taken with a pinch of salt. It is all theory in my head. I’ve never sailed a ketch, nor even seen one. The theory commends itself to me. Wait till I get out on the ocean, then I’ll be able to tell more about the cruising and sailing qualities of the ketch. 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.
