“Never mind their pesky road,” he said to me as we dragged ourselves up a shelf of rock and sat down, panting, to rest. “I’ll get an air machine soon and fool them. I’m clearing a level space for a landing stage for the airships, and next time you come to Tahiti you will alight right at my door.” When she reached the Calvary, instead of turning to the right, she turned to the left and lost herself in coal-yards; she had to retrace her steps; some people she spoke to advised her to hasten. She walked helplessly around the harbour filled with vessels, and knocked against hawsers. Presently the ground sloped abruptly, lights flitted to and fro, and she thought all at once that she had gone mad when she saw some horses in the sky.!

No, adventure is not dead, and in spite of the steam engine and of Thomas Cook & Son. When the announcement of the contemplated voyage of the Snark was made, young men of “roving disposition” proved to be legion, and young women as well—to say nothing of the elderly men and women who volunteered for the voyage. Why, among my personal friends there were at least half a dozen who regretted their recent or imminent marriages; and there was one marriage I know of that almost failed to come off because of the Snark. Whereat we would rehearse for our mutual encouragement the manifold virtues and excellences of the Snark. Also, I would borrow more money, and I would get down closer to my desk and write harder, and I refused heroically to take a Sunday off and go out into the hills with my friends. I was building a boat, and by the eternal it was going to be a boat, and a boat spelled out all in capitals—B—O—A—T; and no matter what it cost I didn’t care. So long as it was a B O A T.

And that is how it came about that I tackled surf-riding. And now that I have tackled it, more than ever do I hold it to be a royal sport. But first let me explain the physics of it. A wave is a communicated agitation. The water that composes the body of a wave does not move. If it did, when a stone is thrown into a pond and the ripples spread away in an ever widening circle, there would appear at the centre an ever increasing hole. No, the water that composes the body of a wave is stationary. Thus, you may watch a particular portion of the ocean’s surface and you will see the same water rise and fall a thousand times to the agitation communicated by a thousand successive waves. Now imagine this communicated agitation moving shoreward. As the bottom shoals, the lower portion of the wave strikes land first and is stopped. But water is fluid, and the upper portion has not struck anything, wherefore it keeps on communicating its agitation, keeps on going. And when the top of the wave keeps on going, while the bottom of it lags behind, something is bound to happen. The bottom of the wave drops out from under and the top of the wave falls over, forward, and down, curling and cresting and roaring as it does so. It is the bottom of a wave striking against the top of the land that is the cause of all surfs. “The total number of degrees is 360. Subtract the 184° west longitude from 360°, and you will get 176° east longitude.” I couldn’t help it. I tell it as a vindication of Roscoe and all the other navigators. The poison of power was working in me. I was not as other men—most other men; I knew what they did not know,—the mystery of the heavens, that pointed out the way across the deep. And the taste of power I had received drove me on. I steered at the wheel long hours with one hand, and studied mystery with the other. By the end of the week, teaching myself, I was able to do divers things. For instance, I shot the North Star, at night, of course; got its altitude, corrected for index error, dip, etc., and found our latitude. And this latitude agreed with the latitude of the previous noon corrected by dead reckoning up to that moment. Proud? Well, I was even prouder with my next miracle. I was going to turn in at nine o’clock. I worked out the problem, self-instructed, and learned what star of the first magnitude would be passing the meridian around half-past eight. This star proved to be Alpha Crucis. I had never heard of the star before. I looked it up on the star map. It was one of the stars of the Southern Cross. What! thought I; have we been sailing with the Southern Cross in the sky of nights and never known it? Dolts that we are! Gudgeons and moles! I couldn’t believe it. I went over the problem again, and verified it. Charmian had the wheel from eight till ten that evening. I told her to keep her eyes open and look due south for the Southern Cross. And when the stars came out, there shone the Southern Cross low on the horizon. Proud? No medicine man nor high priest was ever prouder. Furthermore, with the prayer-wheel I shot Alpha Crucis and from its altitude worked out our latitude. And still furthermore, I shot the North Star, too, and it agreed with what had been told me by the Southern Cross. Proud? Why, the language of the stars was mine, and I listened and heard them telling me my way over the deep.
