Then of a sudden the stump of a mast sank into the water, there was a still greater agitation and a mass of broken timbers shot up into the air and then fell back, and went floating away on the tide.

"That's about the last of her," said Captain Storms, "or, at any rate, you won't go into the cabin again. You've made your last visit to the wreck, and if any one ever gets that money he'll have to dive for it. You can be thankful that you went there when you did."

"So I am," said Jack. "Come on, Dick, pull away from here."


CHAPTER X

A THRILLING ENCOUNTER

Returning to the yacht first for the captain to get aboard, Jack and Percival then took the boat and went to the outer bay on a little exploring trip of their own, the rest not caring to make any more explorations at that time.

The boys guided the boat along shore not too near the rocks, both keeping watch for any nook which might prove of interest or afford an opportunity for an adventure of any sort.

There was a short, keen-bladed hatchet to cut their way through the thicket if necessary when they went ashore, and Percival had a rifle with which to shoot any game they might come across, both being placed on one of the forward thwarts.

Jack was provided with his pocket flashlight in case they went into dark places, and Dick had a revolver in his pocket, declaring that this might be of as much use as the torch in case they came to close quarters with an enemy, no matter of what sort.
