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. Daylight, gray and violent, steals through the cloud-pall and shows a foaming sea that flattens under the weight of recurrent and increasing squalls. Then comes the rain, filling the windy valleys of the sea with milky smoke and further flattening the waves, which but wait for the easement of wind and rain to leap more wildly than before. Come the men on deck, their sleep out, and among them Hermann, his face on the broad grin in appreciation of the breeze of wind I have picked up. I turn the wheel over to Warren and start to go below, pausing on the way to rescue the galley stovepipe which has gone adrift. I am barefooted, and my toes have had an excellent education in the art of clinging; but, as the rail buries itself in a green sea, I suddenly sit down on the streaming deck. Hermann good-naturedly elects to question my selection of such a spot. Then comes the next roll, and he sits down, suddenly, and without premeditation. The Snark heels over and down, the rail takes it green, and Hermann and I, clutching the precious stove-pipe, are swept down into the lee-scuppers. After that I finish my journey below, and while changing my clothes grin with satisfaction—the Snark is making easting.!

During the building of the Snark, Roscoe and I had an agreement, something like this: “I’ll furnish the books and instruments,” I said, “and do you study up navigation now. I’ll be too busy to do any studying. Then, when we get to sea, you can teach me what you have learned.” Roscoe was delighted. Furthermore, Roscoe was as frank and ingenuous and modest as the young men I have described. But when we got out to sea and he began to practise the holy rite, while I looked on admiringly, a change, subtle and distinctive, marked his bearing. When he shot the sun at noon, the glow of achievement wrapped him in lambent flame. When he went below, figured out his observation, and then returned on deck and announced our latitude and longitude, there was an authoritative ring in his voice that was new to all of us. But that was not the worst of it. He became filled with incommunicable information. And the more he discovered the reasons for the erratic jumps of the Snark over the chart, and the less the Snark jumped, the more incommunicable and holy and awful became his information. My mild suggestions that it was about time that I began to learn, met with no hearty response, with no offers on his part to help me. He displayed not the slightest intention of living up to our agreement. Charmian and I looked at each other and debated silently for half a minute. Then we nodded our heads simultaneously. It is a way we have of making up our minds to do things; and a very good way it is when one has no temperamental tears to shed over the last tin-of condensed milk when it has capsized. (We are living on tinned goods these days, and since mind is rumoured to be an emanation of matter, our similes are naturally of the packing-house variety.)

When I should have headed the Snark south-west for Hawaii, I still held her south. I was going to find those flying fish. Finally the time came when, if I wanted to go to Honolulu, I should have headed the Snark due west, instead of which I kept her south. Not until latitude 19° did we encounter the first flying fish. He was very much alone. I saw him. Five other pairs of eager eyes scanned the sea all day, but never saw another. So sparse were the flying fish that nearly a week more elapsed before the last one on board saw his first flying fish. As for the dolphin, bonita, porpoise, and all the other hordes of life—there weren’t any. “I think there’s some dirt in these cuts,” Martin said tentatively, after several days. “I’ll wash them out and then they’ll be all right,” he added, after I had refused to rise to the bait. “Never mind,” Charmian and I said to each other; “think of the wonderful boat it is going to be when it is completed.”
