“Impossible,” I muttered back. “Why should they be giving it to us? Besides, there is no room on the Snark for it. We could not eat a tithe of it. The rest would spoil. Maybe they are inviting us to the feast. At any rate, that they should give all that to us is impossible.” We were close in to the shore and working in closer, stern-first, when a school of fish was sighted. The fuse was ignited and the stick of dynamite thrown. With the explosion, the surface of the water was broken by the flash of leaping fish. At the same instant the woods broke into life. A score of naked savages, armed with bows and arrows, spears, and Sniders, burst out upon the shore. At the same moment our boat’s crew lifted their rifles. And thus the opposing parties faced each other, while our extra boys dived over after the stunned fish.!

My heart almost stood still waiting the answer. By that answer my professional medical prestige stood or fell. Martin, I could see, was quite sure it was going to fall. And then the answer—O blessed answer! 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.

“Altogether you boy belong Solomons you no savvee white man. Me fella me savvee him. Me fella me savvee talk along white man. “The gorilla in the African jungle pounds his chest until the noise of it can be heard half a mile away,” he will announce suddenly, and thereat beat a hair-raising, devil’s tattoo on his own chest.
