Of course all this work was not done in one day. On the afternoon of their arrival at the lake the boys merely pitched the tent, and then went fishing with a view to supper. Fishing with drop-lines from a large rock at one end of their little island, they caught perch as fast as they could pull them in, good-sized pickerel, and two or three cat-fish. That night they ate a supper that would have made a boarding-house keeper weep tears of despair, and went to bed rather happier than they had ever felt before.

Tom was to row over to the house for milk and other provisions in the morning; but when morning came the boat was gone. She had broken loose during the night, not having been properly fastened, and had floated quietly away. A faint speck was visible on the surface of the lake about two miles away, which Harry, who had remarkably good eyes, said was the Whitewing. Whether he was right or wrong, it was quite certain that the boys were imprisoned on the island, with nothing to eat but a can of peaches and some coffee and sugar.

The fish, however, were waiting to be caught, and before very long a breakfast of fish and of coffee without milk was ready. The boys then began to discuss the important question of how they were to get back their boat, or to get away from the island.

It was a mile to the shore, and nobody felt able to swim that distance. Joe proposed that they fasten one of their shirts to a tall tree, as a signal of distress, and then fire the gun every minute. The objection to this plan was that the nearest house was out of sight behind a little point of land, and that no one would see the signal, or would understand why the gun was fired. Then Tom proposed to build a raft, on which two boys could paddle after the runaway boat. This was a practicable suggestion, and it was at once put into execution.

HARRY SETS OUT IN PURSUIT OF THE BOAT.

It was hard work to cut down timber enough to build a raft, but by perseverance the raft was finished before noon. It consisted of four logs laid side by side, and bound together with handkerchiefs, shoe-strings, green twigs, and a few strips from one of Harry’s shirts, which he said was unnecessarily long. It was covered with two or three pieces of flat driftwood; and when it was finished a piece of board was found which was shaped with the hatchet into a rude paddle. Then Tom and Harry proceeded to embark.

The raft floated Harry very well, but promptly sank when Tom also stepped on it. Either more timber must be added to it, or one boy must go alone in search of the boat. Harry insisted upon going at once, and as the lake was perfectly smooth, and he could swim well, there did not seem to be great risk in his making the voyage alone. Bidding the boys good-bye, he paddled slowly away, and left his comrades to anxiously wait for his return.

It was ticklish work paddling the raft. The logs were fastened together so insecurely, owing to the fact that all the rope was in the runaway boat, that Harry was in constant fear that they would come apart, and was obliged to paddle very carefully to avoid putting any strain on the raft. With such a craft speed was out of the question; and after an hour of hard work the raft was only half-way between the island and the boat. Harry was not easily discouraged, however, and he paddled on, knowing that if nothing happened he must reach the boat in course of time.

Something did happen. When, after paddling for more than two hours, the Whitewing was rather less than a quarter of a mile from the raft, Harry missed a stroke with his paddle, and tumbled over. He struck the raft with his shoulder, and went through it as easily as if it had been fastened together with paper. When he came to the surface again he found that the raft had separated into its original logs, and that his voyage on it was ended. Luckily the Whitewing was now within swimming distance, so he struck out for her, and finally crept into her over the stern, so much exhausted that he had to lie down and rest before taking to the oars. Had the raft gone to pieces half an hour sooner he would have been in a dangerous position; for it is doubtful if he could have clung to one of the logs long enough to drift to the shore without becoming totally exhausted.
