And the time continued to go by. One thing was becoming apparent, namely, that it was impossible to finish the Snark in San Francisco. She had been so long in the building that she was beginning to break down and wear out. In fact, she had reached the stage where she was breaking down faster than she could be repaired. She had become a joke. Nobody took her seriously; least of all the men who worked on her. I said we would sail just as she was and finish building her in Honolulu. Promptly she sprang a leak that had to be attended to before we could sail. I started her for the boat-ways. Before she got to them she was caught between two huge barges and received a vigorous crushing. We got her on the ways, and, part way along, the ways spread and dropped her through, stern-first, into the mud. “Wada San, to-morrow morning, your watch, you look sharp on weather-bow you see land.”!

I assured him that if he really did let go and have a swim the sharks would promptly appear. This was a bluff on my part. I didn’t believe it. It lasted as a deterrent for two days. The third day the wind fell calm, and it was pretty hot. The Snark was moving a knot an hour. Bert dropped down under the bowsprit and let go. And now behold the perversity of things. We had sailed across two thousand miles and more of ocean and had met with no sharks. Within five minutes after Bert finished his swim, the fin of a shark was cutting the surface in circles around the Snark. Charmian had been raised a vegetarian and a sanitarian. Her Aunt Netta, who brought her up and who lived in a healthful climate, did not believe in drugs. Neither did Charmian. Besides, drugs disagreed with her. Their effects were worse than the ills they were supposed to alleviate. But she listened to the argument in favour of quinine, accepted it as the lesser evil, and in consequence had shorter, less painful, and less frequent attacks of fever. We encountered a Mr. Caulfeild, a missionary, whose two predecessors had died after less than six months’ residence in the Solomons. Like them he had been a firm believer in homeopathy, until after his first fever, whereupon, unlike them, he made a grand slide back to allopathy and quinine, catching fever and carrying on his Gospel work.

The horse-trail is not very wide. Like the engineer who built it, it dares anything. Where the ditch plunges through the mountain, it climbs over; and where the ditch leaps a gorge on a flume, the horse-trail takes advantage of the ditch and crosses on top of the flume. That careless trail thinks nothing of travelling up or down the faces of precipices. It gouges its narrow way out of the wall, dodging around waterfalls or passing under them where they thunder down in white fury; while straight overhead the wall rises hundreds of feet, and straight beneath it sinks a thousand. And those marvellous mountain horses are as unconcerned as the trail. They fox-trot along it as a matter of course, though the footing is slippery with rain, and they will gallop with their hind feet slipping over the edge if you let them. I advise only those with steady nerves and cool heads to tackle the Nahiku Ditch trail. One of our cow-boys was noted as the strongest and bravest on the big ranch. He had ridden mountain horses all his life on the rugged western slopes of Haleakala. He was first in the horse-breaking; and when the others hung back, as a matter of course, he would go in to meet a wild bull in the cattle-pen. He had a reputation. But he had never ridden over the Nahiku Ditch. It was there he lost his reputation. When he faced the first flume, spanning a hair-raising gorge, narrow, without railings, with a bellowing waterfall above, another below, and directly beneath a wild cascade, the air filled with driving spray and rocking to the clamour and rush of sound and motion—well, that cow-boy dismounted from his horse, explained briefly that he had a wife and two children, and crossed over on foot, leading the horse behind him. For a moment she tottered, and had to sit down. 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.
