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. I had time in the Fijis to compare my chronometer with two other chronometers. Two weeks previous, at Pago Pago, in Samoa, I had asked my captain to compare our chronometer with the chronometers on the American cruiser, the Annapolis. This he told me he had done—of course he had done nothing of the sort; and he told me that the difference he had ascertained was only a small fraction of a second. He told it to me with finely simulated joy and with words of praise for my splendid time-keeper. I repeat it now, with words of praise for his splendid and unblushing unveracity. For behold, fourteen days later, in Suva, I compared the chronometer with the one on the Atua, an Australian steamer, and found that mine was thirty-one seconds fast. Now thirty-one seconds of time, converted into arc, equals seven and one-quarter miles. That is to say, if I were sailing west, in the night-time, and my position, according to my dead reckoning from my afternoon chronometer sight, was shown to be seven miles off the land, why, at that very moment I would be crashing on the reef. Next I compared my chronometer with Captain Wooley’s. Captain Wooley, the harbourmaster, gives the time to Suva, firing a gun signal at twelve, noon, three times a week. According to his chronometer mine was fifty-nine seconds fast, which is to say, that, sailing west, I should be crashing on the reef when I thought I was fifteen miles off from it.!

With two or three exceptions, all the hundreds that volunteered for my crew were very much in earnest. Many of them sent their photographs. Ninety per cent. offered to work in any capacity, and ninety-nine per cent. offered to work without salary. “Contemplating your voyage on the Snark,” said one, “and notwithstanding its attendant dangers, to accompany you (in any capacity whatever) would be the climax of my ambitions.” Which reminds me of the young fellow who was “seventeen years old and ambicious,” and who, at the end of his letter, earnestly requested “but please do not let this git into the papers or magazines.” Quite different was the one who said, “I would be willing to work like hell and not demand pay.” Almost all of them wanted me to telegraph, at their expense, my acceptance of their services; and quite a number offered to put up a bond to guarantee their appearance on sailing date. 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.

From time to time Felicite spoke to shadows. The women left her and Mother Simon sat down to breakfast. Then a new thought came to me. I corrected the Equation of Time for Sunday and for Saturday, making two separate operations of it, and lo, when the results were compared, there was a difference only of four-tenths of a second. I was a changed man. I had found my way out of the crypt. The Snark was scarcely big enough to hold me and my experience. Four-tenths of a second would make a difference of only one-tenth of a mile—a cable-length! Then, to the south, Aneiteum rose out of the sea, to the north, Aniwa, and, dead ahead, Tanna. There was no mistaking Tanna, for the smoke of its volcano was towering high in the sky. It was forty miles away, and by afternoon, as we drew close, never ceasing to log our six knots, we saw that it was a mountainous, hazy land, with no apparent openings in its coast-line. I was looking for Port Resolution, though I was quite prepared to find that as an anchorage, it had been destroyed. Volcanic earthquakes had lifted its bottom during the last forty years, so that where once the largest ships rode at anchor there was now, by last reports, scarcely space and depth sufficient for the Snark. And why should not another convulsion, since the last report, have closed the harbour completely?
