Owen and Nat had been sleeping for a couple of hours or more, when they were aroused by Mike's voice. "Bedad! but the weather has changed entirely, and our beautiful fire has gone flying away right over the island," he exclaimed. Owen and Nat started up. A fierce gale was raging, threatening every instant to carry away their tent; while the sea, which had hitherto only lapped the edge of the sand-bank, now came foaming up against it in heavy billows. "The boat, the boat!" cried Owen. "Our first care must be to secure her, if she is not knocked to pieces already. She is of more importance than the tent or anything else." They hurried off to where the boat lay, some little distance from their tent. They were but just in time, as already the sea had driven her broadside to the beach and had begun to break into her. She was already nearly half full of water, and, being thus very heavy, they could only drag her up a foot or two. Fortunately there came a lull. "If we had anything to bale her out with we might succeed," observed Owen. "The lid of the kettle will be the thing," cried Mike. "Nat, run and get it!" Nat was not a couple of minutes away, and, jumping into the boat, he baled away with all his might, while Mike and Owen endeavoured to drag her up. The greater part of the water having been baled out of her they succeeded better than at first, and at length got her, as they hoped, beyond the reach of the seas. The stake to which she was secured was then carried up as far as the painter would allow, and then fixed as deeply as possible into the sand. The tent had withstood the wind, and they further secured it by placing the casks and bales on the lower part of the cloth, so that, although it might be torn, it was not likely to be carried bodily away. They were thus engaged when they heard shouts and cries coming from the direction of the camp. The cause was too evident. The sea, driven by the wind, had risen considerably, and was rolling much further up the higher part of the bank than it had hitherto done. Too probably, therefore, it was sweeping over the lower end, on which their shipmates had remained. "The sea must have caught them while they were still asleep, and they have only just discovered their danger," exclaimed Owen. "They won't know in which direction to run, and they are not aware of this higher spot on which they might take refuge." "Thin the best way will be to light up a bit of fire to show them the way," said Mike. "There are a few embers up there still burning." Mike and Nat quickly collected some of the burning pieces of wood, and a small fire was soon blazing up. It required constant watchfulness, however, to prevent it from being blown away. In the meantime Owen and his companions shouted together at the top of their voices.
