“It’s down in the cave now,” said Joe. Tom gave a start. “There’s a meat-pie in it that is good for a dinner to-morrow, and a big frosted cake, if you fellows want it to-night.” “Hooray!” cried Jack Harvey. “You and I will go and get it.” Whereupon he and Joe sprang up and made directly for the spot where Tom lay, passing by so close that he could have reached out and touched them, and hurried along the bank, down to the shore. Tom allowed them to get well in advance before he ventured to crawl from his hiding-place and follow them. He saw them at length disappear over the bank at a point where there grew a thick clump of cedars. He turned from the path into the woods, made his way cautiously past the place where he had seen them disappear, turned into the path again, and then climbed down the bank, which was there very steep, holding on to the bushes, and looked for the boys, but they were nowhere to be seen. Tom knew they could not have passed him. They had not reappeared over the edge of the bank, and they were nowhere in sight along the shore. There could be but one conclusion. The entrance to the cave must be located in the clump of cedars. It seemed to Tom that he had waited at least a quarter of an hour, though, in fact, it was not more than five minutes, when he saw the boys reappear. Tom groaned as he saw the big cake in Joe’s hand. Joe laid it down on the ground, while he and Jack picked up several armfuls of loose boughs lying about, and threw them up carelessly against the bank. Then Joe took up the cake again, and they emerged from the cedars, climbed up over the bank, and disappeared in the direction of their camp. Tom lost no time in scrambling to the spot. The hiding-place was cunningly concealed. It was an awkward place to crawl to from any part of the bank, and no one would have thought of trying to land there in a boat. The entrance to the cave might have been left open, with little chance of its ever being discovered. Tom threw aside the boughs sufficiently to discover that beneath them was a sort of trap-door, made of pieces of board carelessly nailed together. Then he replaced the boughs and, without even attempting to lift the board door, regained the path at the top of the bank. “There’ll be time enough to explore that later,” he muttered. “I’m not the only one that will have lost something out of that cave before morning, though.” He made his way cautiously past the camp once more, and then started on a run for his own camp. His hare and hounds practice at school stood him in good stead, and he did not stop running till he had come to the door of his tent. He unfastened the flap and entered, panting for breath. Bob was sleeping soundly. He shook him, but Bob was loath to awake, and resented being so roughly disturbed. “Wake up, Bob! Wake!” cried Tom, shaking him again. Bob opened his eyes. “Why, is it morning, Tom?” he asked.
