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. The Cambrian had come to punish the murderers of the Minota’s captain, but what she had succeeded in doing we did not learn until later in the day, when a Mr. Abbot, a missionary, came alongside in his whale-boat. The villages had been burned and the pigs killed. But the natives had escaped personal harm. The murderers had not been captured, though the Minota’s flag and other of her gear had been recovered. The drowning of the baby had come about through a misunderstanding. Chief Johnny, of Binu, had declined to guide the landing party into the bush, nor could any of his men be induced to perform that office. Whereupon Captain Lewes, righteously indignant, had told Chief Johnny that he deserved to have his village burned. Johnny’s bêche de mer English did not include the word “deserve.” So his understanding of it was that his village was to be burned anyway. The immediate stampede of the inhabitants was so hurried that the baby was dropped into the water. In the meantime Chief Johnny hastened to Mr. Abbot. Into his hand he put fourteen sovereigns and requested him to go on board the Cambrian and buy Captain Lewes off. Johnny’s village was not burned. Nor did Captain Lewes get the fourteen sovereigns, for I saw them later in Johnny’s possession when he boarded the Minota. The excuse Johnny gave me for not guiding the landing party was a big boil which he proudly revealed. His real reason, however, and a perfectly valid one, though he did not state it, was fear of revenge on the part of the bushmen. Had he, or any of his men, guided the marines, he could have looked for bloody reprisals as soon as the Cambrian weighed anchor.!

One morning during the terrible winter of 1837, when she had put him in front of the fire-place on account of the cold, she found him dead in his cage, hanging to the wire bars with his head down. He had probably died of congestion. But she believed that he had been poisoned, and although she had no proofs whatever, her suspicion rested on Fabu. By this time the Snark was at sea on her way to Fiji. I remembered the French sailor, and for the first time became seriously alarmed. Four other similar sores had appeared—or ulcers, rather, and the pain of them kept me awake at night. All my plans were made to lay up the Snark in Fiji and get away on the first steamer to Australia and professional M.D.’s. In the meantime, in my amateur M.D. way, I did my best. I read through all the medical works on board. Not a line nor a word could I find descriptive of my affliction. I brought common horse-sense to bear on the problem. Here were malignant and excessively active ulcers that were eating me up. There was an organic and corroding poison at work. Two things I concluded must be done. First, some agent must be found to destroy the poison. Secondly, the ulcers could not possibly heal from the outside in; they must heal from the inside out. I decided to fight the poison with corrosive sublimate. The very name of it struck me as vicious. Talk of fighting fire with fire! I was being consumed by a corrosive poison, and it appealed to my fancy to fight it with another corrosive poison. After several days I alternated dressings of corrosive sublimate with dressings of peroxide of hydrogen. And behold, by the time we reached Fiji four of the five ulcers were healed, while the remaining one was no bigger than a pea.

CHAPTER VII THE LEPERS OF MOLOKAI Two more days passed, but the cuts did not pass, and I caught Martin soaking his feet and legs in a pail of hot water. “The Correct Magnetic Course is derived from the True Course by applying to it the variation.”
