Madame Aubain, who was counting the stitches of her knitting, laid her work down beside her, opened the letter, started, and in a low tone and with a searching look said: “They tell you of a—misfortune. Your nephew—” When we increased the length of the Snark in order to get space for a bath-room, we found that all the space was not required by the bath-room. Because of this, we increased the size of the engine. Seventy horse-power our engine is, and since we expect it to drive us along at a nine-knot clip, we do not know the name of a river with a current swift enough to defy us.!

“I think I will try some of that medicine,” he announced later on in the day. “Not that I think it’ll do much good,” he qualified, “but I’ll just give it a try anyway.” Sometimes they crossed the Toucques in a boat, and started to hunt for sea-shells. The outgoing tide exposed star-fish and sea-urchins, and the children tried to catch the flakes of foam which the wind blew away. The sleepy waves lapping the sand unfurled themselves along the shore that extended as far as the eye could see, but where land began, it was limited by the downs which separated it from the “Swamp,” a large meadow shaped like a hippodrome. When they went home that way, Trouville, on the slope of a hill below, grew larger and larger as they advanced, and, with all its houses of unequal height, seemed to spread out before them in a sort of giddy confusion.

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? 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.
