“What are you going to do now, Tom?” queried Bob. “We don’t want to take anything of theirs, of course.”

“Not a thing,” answered Tom. “We don’t go in for that sort of business, but I just want to show them that we have been here and had the opportunity to destroy anything that we were of a mind to. Perhaps it will teach them a good lesson. It will show them that we are as smart as they are, anyway.”

So saying, Tom began to gather up the guns, the good sails, the boxes of provisions, and other things of value, and carry them outside the cave, setting them down on the bank at some distance from the mouth of it.

“We won’t destroy anything of value,” said Tom. “But here are some odds and ends of old stuff, some of these pieces of oars, empty crates, bagging, and that sort of thing, which will make a good blaze, and which would have to be thrown away some day. They are of no use to anybody. I propose to make a bonfire of these in the cave, just to show Jack Harvey that we have been here. He’ll find all his stuff that’s good for anything put carefully outside the cave, and no harm come to it. But he’ll be just as furious to find his cave discovered and on fire, for all that.”

“All right,” said Bob, “here goes.”

Bob was thinking of that cake.

Tom took one of the axes and chopped a small hole in the top of the cave, some distance above the door.

“That will make a draught,” he said, in answer to Bob’s inquiry.

Then he blew out the lantern and poured the oil with which it was filled over the pile of rubbish. There was still a small heap of stuff in one corner of the cave, some old boards, and a few pieces of sail, thrown carelessly in a pile, as though of no value. They did not stop to bother with these, as they seemed of no consequence, and they were in a hurry.

Tom struck a match and set fire to the heap that he had accumulated.
