Now Deviation is the variation in the needle caused by the distribution of iron on board of ship. This purely local variation I derived from the deviation card of my standard compass and then applied to the Correct Magnetic Course. The result was the Compass Course. And yet, not yet. My standard compass was amidships on the companionway. My steering compass was aft, in the cockpit, near the wheel. When the steering compass pointed west-by-south three-quarters-south (the steering course), the standard compass pointed west-one-half-north, which was certainly not the steering course. I kept the Snark up till she was heading west-by-south-three-quarters-south on the standard compass, which gave, on the steering compass, south-west-by-west. “Silly!” cries my literal mind. “You are 8:9 A.M. and Greenwich is 8:25 P.M.”!

“Will you have some iced tea?” asked the Madonna; and then her side of the table sank down gently and I said yes to her at an angle of forty-five degrees. Then there was the matter of delay. I dealt with forty-seven different kinds of union men and with one hundred and fifteen different firms. And not one union man and not one firm of all the union men and all the firms ever delivered anything at the time agreed upon, nor ever was on time for anything except pay-day and bill-collection. Men pledged me their immortal souls that they would deliver a certain thing on a certain date; as a rule, after such pledging, they rarely exceeded being three months late in delivery. And so it went, and Charmian and I consoled each other by saying what a splendid boat the Snark was, so staunch and strong; also, we would get into the small boat and row around the Snark, and gloat over her unbelievably wonderful bow.

P.S. Well, anyway, I’ve cured the chronometer. After knocking about the sea for eight squally, rainy days, most of the time hove to, I succeeded in catching a partial observation of the sun at midday. From this I worked up my latitude, then headed by log to the latitude of Lord Howe, and ran both that latitude and the island down together. Here I tested the chronometer by longitude sights and found it something like three minutes out. Since each minute is equivalent to fifteen miles, the total error can be appreciated. By repeated observations at Lord Howe I rated the chronometer, finding it to have a daily losing error of seven-tenths of a second. Now it happens that a year ago, when we sailed from Hawaii, that selfsame chronometer had that selfsame losing error of seven-tenths of a second. Since that error was faithfully added every day, and since that error, as proved by my observations at Lord Howe, has not changed, then what under the sun made that chronometer all of a sudden accelerate and catch up with itself three minutes? Can such things be? Expert watchmakers say no; but I say that they have never done any expert watch-making and watch-rating in the Solomons. That it is the climate is my only diagnosis. At any rate, I have successfully doctored the chronometer, even if I have failed with the lunacy cases and with Martin’s yaws. 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. 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.
