We ran down the lagoon from Langa Langa, between mangrove swamps, through passages scarcely wider than the Minota, and past the reef villages of Kaloka and Auki. Like the founders of Venice, these salt-water men were originally refugees from the mainland. Too weak to hold their own in the bush, survivors of village massacres, they fled to the sand-banks of the lagoon. These sand-banks they built up into islands. They were compelled to seek their provender from the sea, and in time they became salt-water men. They learned the ways of the fish and the shellfish, and they invented hooks and lines, nets and fish-traps. They developed canoe-bodies. Unable to walk about, spending all their time in the canoes, they became thick-armed and broad-shouldered, with narrow waists and frail spindly legs. Controlling the sea-coast, they became wealthy, trade with the interior passing largely through their hands. But perpetual enmity exists between them and the bushmen. Practically their only truces are on market-days, which occur at stated intervals, usually twice a week. The bushwomen and the salt-water women do the bartering. Back in the bush, a hundred yards away, fully armed, lurk the bushmen, while to seaward, in the canoes, are the salt-water men. There are very rare instances of the market-day truces being broken. The bushmen like their fish too well, while the salt-water men have an organic craving for the vegetables they cannot grow on their crowded islets. “Come on for a sail,” I called below to Charmian. “But put on your swimming suit. It’s going to be wet.”!

The day we sailed for Bora Bora the wind was light, and we crossed the lagoon under power to the point where Tehei and Bihaura were to meet us. As we made in to the land between the coral banks, we vainly scanned the shore for our friends. There was no sign of them. Raiatea and Tahaa are unique in that they lie inside the same encircling reef. Both are volcanic islands, ragged of sky-line, with heaven-aspiring peaks and minarets. Since Raiatea is thirty miles in circumference, and Tahaa fifteen miles, some idea may be gained of the magnitude of the reef that encloses them. Between them and the reef stretches from one to two miles of water, forming a beautiful lagoon. The huge Pacific seas, extending in unbroken lines sometimes a mile or half as much again in length, hurl themselves upon the reef, overtowering and falling upon it with tremendous crashes, and yet the fragile coral structure withstands the shock and protects the land. Outside lies destruction to the mightiest ship afloat. Inside reigns the calm of untroubled water, whereon a canoe like ours can sail with no more than a couple of inches of free-board.

For a hundred francs a year, she cooked and did the housework, washed, ironed, mended, harnessed the horse, fattened the poultry, made the butter and remained faithful to her mistress—although the latter was by no means an agreeable person. 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. 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.
