"Hello! what is this?" exclaimed Percival. "A cave, or what?"
Just before them was a jagged opening into some region beyond, but whether it was a cave or not puzzled them.
Jack went closer, and held his light in the jagged opening.
"It's a hole in the side of a vessel, Dick!" he cried in amazement.
CHAPTER VI
A WALK UNDER WATER
"That's what it is, Jack," said Dick, after the first sensation of astonishment had passed. "It is more in the bow than on the side, however. You can see how she narrows a little farther on. This hole is pretty well forward. I tell you what! This is the vessel we saw under water, or the one that stump of a mast belongs to, at any rate."
"I believe it is, Dick. Probably she drove in here, had a hole smashed in her bow, and then sank. The earth has settled in between the masses of rock above and around her, and hidden her, but there is still the fissure down which we have just come."
"This is as good as finding Captain Kidd's treasure, isn't it?" exclaimed young Smith. "We never expected to find anything. Shall we go in and see what more there is, Jack?"
