“When shall we start?” 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.!

After that I was ready to meet all comers—just the proper state of mind for a Waterloo. And it came. Its name was Tomi. He was a strapping giant of a heathen with a bad reputation. He was addicted to deeds of violence. Among other things he had beaten two of his wives to death with his fists. His father and mother had been naked cannibals. When he sat down and I put the forceps into his mouth, he was nearly as tall as I was standing up. Big men, prone to violence, very often have a streak of fat in their make-up, so I was doubtful of him. Charmian grabbed one arm and Warren grabbed the other. Then the tug of war began. The instant the forceps closed down on the tooth, his jaws closed down on the forceps. Also, both his hands flew up and gripped my pulling hand. I held on, and he held on. Charmian and Warren held on. We wrestled all about the shop. 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.

Nevertheless we found ourselves once more in the high seat of abundance. The orator, by gestures unmistakable, in detail presented every item in the mountain to us, and next he presented it to us in toto. It was an embarrassing moment. What would you do if you lived in a hall bedroom and a friend gave you a white elephant? Our Snark was no more than a hall bedroom, and already she was loaded down with the abundance of Tahaa. This new supply was too much. We blushed, and stammered, and mauruuru’d. We mauruuru’d with repeated nui’s which conveyed the largeness and overwhelmingness of our thanks. At the same time, by signs, we committed the awful breach of etiquette of not accepting the present. The himine singers’ disappointment was plainly betrayed, and that evening, aided by Tehei, we compromised by accepting one chicken, one bunch of bananas, one bunch of taro, and so on down the list. He arrived, looking unwontedly stiff and uncomfortable in a cotton jacket. When invited to peel it off, he beamed his gratitude and joy, and did so, revealing his sun-gold skin, from waist to shoulder, covered only by a piece of fish-net of coarse twine and large of mesh. A scarlet loin-cloth completed his costume. I began my acquaintance with him that night, and during my long stay in Tahiti that acquaintance ripened into friendship. I confess my sleep was not
