The boys went down to the beach, and Bob washed his face in the salt water.

“I’m all right now, Tom, old fellow,” he said, “but, honest, Tom, I feel ugly enough at being waked up, not at you, though, to just enjoy a fight with those fellows.”

“There’s little prospect of that, if we are careful,” answered Tom. “What we want to do is to show them we are smart enough to get the box back, and, perhaps, play them a trick of our own.”

Then they carried the canoe down to the shore, launched it, and set off. It was about one o’clock in the morning. They paddled away from the tent and down along the shore, noiselessly as Indians. Past the village and past the cottages, and not a sign of life anywhere, not even a wisp of smoke from a chimney. The canoe glided swiftly along, making the only ripples there were on the glassy surface of the bay.

As they came to the beach near Harvey’s camp, they landed, and Tom crept up over the bank to reconnoitre. He came back presently, reporting that the crew were all sound asleep, and everything quiet around the camp. Then they paddled quickly by the end of the bluff and along the bold shore beyond, picking their way carefully among the reefs, as they could not have done in these unknown waters with any other craft than the buoyant canoe.

They disembarked at the clump of cedars, and made the canoe fast to the trunk of one that overhung the water. Tom took from the bow of the canoe a lantern, and they scrambled up the bank. Throwing aside the boughs, they disclosed the trap-door, which they lifted up. Tom lit the lantern and they entered the cave.

They found it much larger than the opening indicated. It was excavated from the hard clay of which the bank was composed, and, though not high enough for them to stand quite erect, it was about eight feet long and five feet wide.

It was filled with stuff of all sorts. There were spare topsails and staysails,—possibly from coasters that had anchored in the harbour,—sets of oars from ships’ boats, several boxes of canned goods, that the grocer of the village had hunted for far and wide, coils of rope, two shotguns, carefully wrapped in pieces of flannel and well oiled, to prevent the rust from eating them, four lanterns, two axes and a hatchet, and odds and ends of all descriptions useful in and about a camp or a yacht.

The roof of the cave was shored up with boards, supported by joists. In one corner of the cave was the box for which they sought, broken into, and with the gorgeous cake gone; but that was all. The rest of the contents were untouched.

They took the box, carried it down to the shore and placed it in the canoe. Tom started to return to the cave.
