It was a moment or two before Frank saw her, and then he started and cast a quick glance at the strip of beach left uncovered by the ebbing tide. The breeze was off the shore, and on arriving they had thrown over a lump of iron with a rope made fast to it and then paddled the canoe ashore and shoved her out again to drift off as far as the rope would allow her, in order to avoid dragging her down over the rough stones when they went away. Now she seemed farther off than she should have been, and in another moment he realized that she was moving. "She's adrift!" he shouted. "Then we will have to get her," Harry answered. Frank laid down his gun and threw off his jacket. Harry could swim better than he could, but Harry was some distance back and the beach was very rough, while it was clear that every moment would increase the distance between it and the canoe. He struck his knees against something which hurt as he floundered into the water stumbling among the stones, but that did not matter then, and as soon as it was deep enough he flung himself down. A horrible chill struck through him as he swung his left arm out, and he was badly hampered by his boots and clothes, and though he swam savagely the canoe was still some way in front of him when at length he turned breathlessly upon his breast. What was worse, she was steadily drifting farther off shore. Chilled and anxious as he was, he thought quickly. He was far from certain that he could get back to the beach, and even if he did so, he would have to spend the night wet through without any means of making a shelter. The sloop was lying a good way out and he did not think that Harry could swim so far in that cold water. He was quite sure that he could not, and it was evident that there was nothing for it but to overtake the canoe. For what seemed a very long time he swam desperately, and then just as he was almost alongside the craft something came up behind him and seized his arm. Turning his head with a half-choked cry, he saw that it was the dog, who apparently intended to stick fast to him. The animal, however, hampered him terribly, and flinging it off he made a last effort and contrived to clutch the canoe before it seized him again. Holding on by the low stern he tried to recover his breath, while he wondered if he could manage to lift himself in. It seemed to him that if he failed to do it at that moment he could not expect to succeed afterward, in which case he would in all probability have to let go before very long. Setting his lips he made the attempt, and falling headforemost into the canoe he lay still for a few moments gasping, until he rose and pulled the dog on board. Then he hauled up the iron, which was still attached to the rope, though it was not upon the bottom, and found a paddle. Two or three minutes later he was back at the beach, and Harry got in. "Make for the sloop as fast as you can," he said.
