But to return. Please do not think that I already know it all. I know only the rudiments of navigation. There is a vast deal yet for me to learn. On the Snark there is a score of fascinating books on navigation waiting for me. There is the danger-angle of Lecky, there is the line of Sumner, which, when you know least of all where you are, shows most conclusively where you are, and where you are not. There are dozens and dozens of methods of finding one’s location on the deep, and one can work years before he masters it all in all its fineness. Commend me the white race when it comes to grit and surviving. One of our two Japanese and both our Tahitians funked and had to be slapped on the back and cheered up and dragged along by main strength toward life. Charmian and Martin took their afflictions cheerfully, made the least of them, and moved with calm certitude along the way of life. When Wada and Henry were convinced that they were going to die, the funeral atmosphere was too much for Tehei, who prayed dolorously and cried for hours at a time. Martin, on the other hand, cursed and got well, and Charmian groaned and made plans for what she was going to do when she got well again.!

Captain Jansen explained. But I fooled the pair of them, and dosed them with their own medicine, which was faith-cure. They had faith in their funk that they were going to die. I slammed a lot of quinine down their throats and took their temperature. It was the first time I had used my medicine-chest thermometer, and I quickly discovered that it was worthless, that it had been produced for profit and not for service. If I had let on to my two patients that the thermometer did not work, there would have been two funerals in short order. Their temperature I swear was 105°. I solemnly made one and then the other smoke the thermometer, allowed an expression of satisfaction to irradiate my countenance, and joyfully told them that their temperature was 94°. Then I slammed more quinine down their throats, told them that any sickness or weakness they might experience would be due to the quinine, and left them to get well. And they did get well, Wada in spite of himself. If a man can die through a misapprehension, is there any immorality in making him live through a misapprehension?

But it is on the western slopes of Haleakala that the main battle goes on. Here Naulu masses his heaviest formations and wins his greatest victories. Ukiukiu grows weak toward late afternoon, which is the way of all trade-winds, and is driven backward by Naulu. Naulu’s generalship is excellent. All day he has been gathering and packing away immense reserves. As the afternoon draws on, he welds them into a solid column, sharp-pointed, miles in length, a mile in width, and hundreds of feet thick. This column he slowly thrusts forward into the broad battle-front of Ukiukiu, and slowly and surely Ukiukiu, weakening fast, is split asunder. But it is not all bloodless. At times Ukiukiu struggles wildly, and with fresh accessions of strength from the limitless north-east, smashes away half a mile at a time of Naulu’s column and sweeps it off and away toward West Maui. Sometimes, when the two charging armies meet end-on, a tremendous perpendicular whirl results, the cloud-masses, locked together, mounting thousands of feet into the air and turning over and over. A favourite device of Ukiukiu is to send a low, squat formation, densely packed, forward along the ground and under Naulu. When Ukiukiu is under, he proceeds to buck. Naulu’s mighty middle gives to the blow and bends upward, but usually he turns the attacking column back upon itself and sets it milling. And all the while the ragged little skirmishers, stray and detached, sneak through the trees and canyons, crawl along and through the grass, and surprise one another with unexpected leaps and rushes; while above, far above, serene and lonely in the rays of the setting sun, Haleakala looks down upon the conflict. And so, the night. But in the morning, after the fashion of trade-winds, Ukiukiu gathers strength and sends the hosts of Naulu rolling back in confusion and rout. And one day is like another day in the battle of the clouds, where Ukiukiu and Naulu strive eternally on the slopes of Haleakala. Therefore, I reasoned, if the compass points 9° 40′ eastward of north, and I wanted to sail due north, I should have to steer 9° 40′ westward of the north indicated by the compass and which was not north at all. So I added 9° 40′ to the left of my west-by-south course, thus getting my correct Magnetic Course, and was ready once more to run to open sea. 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.
