And now for another phase of the physics of surf-riding. All rules have their exceptions. It is true that the water in a wave does not travel forward. But there is what may be called the send of the sea. The water in the overtoppling crest does move forward, as you will speedily realize if you are slapped in the face by it, or if you are caught under it and are pounded by one mighty blow down under the surface panting and gasping for half a minute. The water in the top of a wave rests upon the water in the bottom of the wave. But when the bottom of the wave strikes the land, it stops, while the top goes on. It no longer has the bottom of the wave to hold it up. Where was solid water beneath it, is now air, and for the first time it feels the grip of gravity, and down it falls, at the same time being torn asunder from the lagging bottom of the wave and flung forward. And it is because of this that riding a surf-board is something more than a mere placid sliding down a hill. In truth, one is caught up and hurled shoreward as by some Titan’s hand. The feast ended, we watched the moon rise over Typee. The air was like balm, faintly scented with the breath of flowers. It was a magic night, deathly still, without the slightest breeze to stir the foliage; and one caught one’s breath and felt the pang that is almost hurt, so exquisite was the beauty of it. Faint and far could be heard the thin thunder of the surf upon the beach. There were no beds; and we drowsed and slept wherever we thought the floor softest. Near by, a woman panted and moaned in her sleep, and all about us the dying islanders coughed in the night.!

It was the first time that this had ever happened, for Madame Aubain was not of an expansive nature. Felicite was as grateful for it as if it had been some favour, and thenceforth loved her with animal-like devotion and a religious veneration. “That’s all very well,” my literal mind continues, “If I were in Greenwich I might be in yesterday. Strange things happen in Greenwich. But I know as sure as I am living that I am here, now, in to-day, June 7, and that I took the sun here, now, to-day, June 7. Therefore, I must correct the sun here, now, to-day, June 7.”

And that is how it came about that I tackled surf-riding. And now that I have tackled it, more than ever do I hold it to be a royal sport. But first let me explain the physics of it. A wave is a communicated agitation. The water that composes the body of a wave does not move. If it did, when a stone is thrown into a pond and the ripples spread away in an ever widening circle, there would appear at the centre an ever increasing hole. No, the water that composes the body of a wave is stationary. Thus, you may watch a particular portion of the ocean’s surface and you will see the same water rise and fall a thousand times to the agitation communicated by a thousand successive waves. Now imagine this communicated agitation moving shoreward. As the bottom shoals, the lower portion of the wave strikes land first and is stopped. But water is fluid, and the upper portion has not struck anything, wherefore it keeps on communicating its agitation, keeps on going. And when the top of the wave keeps on going, while the bottom of it lags behind, something is bound to happen. The bottom of the wave drops out from under and the top of the wave falls over, forward, and down, curling and cresting and roaring as it does so. It is the bottom of a wave striking against the top of the land that is the cause of all surfs. That settled him, for he worried my dreams no more; and it settled me, too, for I woke up chuckling at the episode. It was three in the morning. I went up on deck. Henry, the Rapa islander, was steering. I looked at the log. It recorded forty-two miles. The Snark had not abated her six-knot gait, and she had not struck Futuna yet. At half-past five I was again on deck. Wada, at the wheel, had seen no land. I sat on the cockpit rail, a prey to morbid doubt for a quarter of an hour. Then I saw land, a small, high piece of land, just where it ought to be, rising from the water on the weather-bow. At six o’clock I could clearly make it out to be the beautiful volcanic cone of Futuna. At eight o’clock, when it was abreast, I took its distance by the sextant and found it to be 9.3 miles away. And I had elected to pass it 10 miles away! As for myself, I’d rather be that man than the fellows who sit on the bank and watch him. That is why I am building the Snark. I am so made. I like, that is all. The trip around the world means big moments of living. Bear with me a moment and look at it. Here am I, a little animal called a man—a bit of vitalized matter, one hundred and sixty-five pounds of meat and blood, nerve, sinew, bones, and brain,—all of it soft and tender, susceptible to hurt, fallible, and frail. I strike a light back-handed blow on the nose of an obstreperous horse, and a bone in my hand is broken. I put my head under the water for five minutes, and I am drowned. I fall twenty feet through the air, and I am smashed. I am a creature of temperature. A few degrees one way, and my fingers and ears and toes blacken and drop off. A few degrees the other way, and my skin blisters and shrivels away from the raw, quivering flesh. A few additional degrees either way, and the life and the light in me go out. A drop of poison injected into my body from a snake, and I cease to move—for ever I cease to move. A splinter of lead from a rifle enters my head, and I am wrapped around in the eternal blackness.
