The little stream of the Larve had long been the acknowledged puzzle of the whole neighborhood. After skirting the town for some distance, it vanished into the earth through a narrow cleft, and was seen no more. Where it went to after that, no one could tell; and, as we have seen, the first attempt to find out had succeeded so badly that nobody felt much inclined for a second.

Tired out at length, the unsuccessful fishers went home, inwardly resolving to try whether they might not have better fortune by night than by day. Pierre, indeed, when the night came, began to have some doubts about the wisdom of the idea, having heard his father say once and again that it was a very dangerous thing to attempt at that season. But the hardest thing in the world for a boy to do is to draw back from anything simply because it is dangerous. Rather than let Jack think him afraid, Pierre would have gone to sea on a hen-coop; so they stole out of the cottage as noiselessly as possible, and away they went over the dim gray waste of sea, half lighted by the rising moon.

The "take" of fish was a very good one this time, and the boys began to think their night voyage a lucky idea; but they were rejoicing too soon. A little after midnight the sky began to cloud over and the sea to rise in a way which showed that there was a storm brewing. They put about at once, and made for the shore, but long before they reached it the storm burst upon them in all its fury.

In an instant the boat was half full of water, and it was all they could do to keep her from foundering outright, as they flew through the great white roaring waves, thumped and banged about from side to side, and drenched to the skin at every plunge by the flying gusts of spray. Pierre grasped the tiller in his half-numbed hands, while Jack held on with all his might to the "sheet" that steadied their little three-cornered sail, at which the wind tugged as if meaning to tear it away altogether.

The little craft held her own gallantly, and the young sailors began to hope that, after all, they might make the entrance of the bay without accident. But just then an unlucky shift of the wind tore the sail clean away, and the boat, falling off at once, was swept helplessly toward the formidable cliffs beyond.

"Not much chance for us now," said Jack, shaking his head. "Pierre, my boy, I'm sorry I've brought you into this mess; it's all my fault."

"Not a bit, old fellow. I ought to have warned you of what I'd heard my father say. However, if the worst comes to the worst, we can swim for it."

However, there seemed to be little hope, for not a foot of standing-room was to be seen on the rocky sides of the vast black precipice upon which they were driving headlong. All at once Jack shouted:

"Port your helm, Pierre—port! We'll do it yet."

His keen eye had detected a cleft in the rock, just wide enough for the boat to enter.
