Some time in the middle of the night Joe Sharpe woke up from a dream that he had fallen into the river, and could not get out. He thought that he had caught hold of the supports of a bridge, and had drawn himself partly out of the water, but that he had not strength enough to drag his legs out, and that, on the contrary, he was slowly sinking back. When he awoke he found that he was very cold, and that his blanket felt particularly heavy. He put his hand down to move the blanket, when, to his great surprise, he found that he was lying with his legs in a pool of water.
Joe instantly shouted to the other boys, and told them to wake up, for it was raining, and the tent was leaking. As each boy woke up he found himself as wet as Joe, and at first all supposed that it was raining heavily. They soon found, however, that no rain-drops were pattering on the outside of the tent, and that the stars were shining through the open nap.
"There's water in this tent," said Tom, with the air of having made a grand discovery.
"If any of you fellows have been throwing water on me, it was a mean trick," said Jim.
All at once an idea struck Harry. "Boys," he exclaimed, "it's the tide! We've got to get out of this place mighty quick, or the tide will wash the tent away."
The boys sprung up, and rushed out of the tent. They had gone to bed at low tide, and as the tide rose it had gradually invaded the tent. The boat was still safe, but the water had surrounded it, and in a very short time would be deep enough to float it. The tide was still rising, and it was evident that no time should be lost if the tent was to be saved.
Two of the boys hurriedly seized the blankets and other articles which were in the tent, and carried them on to the higher ground, while the other two pulled up the pins, and dragged the tent out of reach of the water. Then they pulled the boat farther up the beach, and having thus made everything safe, had leisure to discover that they were miserably cold, and that their clothes, from the waist down, were wet through.
Luckily, their spare clothing, which they had used for pillows, was untouched by the water, so that they were able to put on dry shirts and trousers. Their blankets, however, had been thoroughly soaked, and it was too cold to think of sleeping without them. There was nothing to be done but to build a fire, and sit around it until daylight. It was by no means easy to collect fire-wood in the dark; and as soon as a boy succeeded in getting an armful of driftwood, he usually stumbled and fell down with it. There was not very much fun in this; but when the fire finally blazed up, and its pleasant warmth conquered the cold night air, the boys began to regain their spirits.
"I wonder what time it is?" said one.
Tom had a watch, but he had forgotten to wind it up for two or three nights, and it had stopped at eight o'clock. The boys were quite sure, however, that they could not have been asleep more than half an hour.
