Not four yards between them now; and, making a few frantic efforts, the lad forced himself through the water in his effort to lessen the distance and grasp the sheep, when suddenly the surface was parted; a bare arm and hand appeared clutching at the air, then another just level with the surface, and before he could avoid it, he was clutched in the death-grip of the drowning boy and borne under, the current seeming to roll them over, down into the darkness of the thick water which roared and thundered in his ears. Richard's first impulse was to struggle free, his next to force himself to the surface; but both efforts were in vain. He was as firmly bound as if he had been chained, and a horrible feeling of despair attacked him as he felt that he was losing consciousness fast, that all was over, and the end at hand. Then, as his senses were leaving him, there was a gleam of daylight for an instant as he and his companion were rolled over by the current. The darkness deepened, and there was a violent shock, the tearing and rending of boughs, and light once more. For a few minutes Richard could do nothing but cling instinctively to the twiggy bough up which he had struggled till his face was a little above the surface, his hands a few inches higher still, and his body dragged out level with the water; while it seemed to him that the unfortunate boy he had tried to save was tugging violently at his waist to drag him from his hold, bending and shaking the bough till it swayed to and fro like a spring. For some little time his clinging was instinctive, every fibre in his body naturally resisting the savage jerks to tear him from his hold; but by degrees he recovered sufficiently to realise his position, and his heart gave a great leap as he found for certain that, though something which felt like a ragged garment was wound about his legs, he was once more free, and that his drowning companion's grasp had been torn away when the furious current swept them into the tree. Of its force he kept on gaining fresh consciousness as the tugging continued and the tree yielded and sprung back, and with this consciousness something of the horror of his position passed away. It was the strong current he had to deal with alone. And now, as he drew his breath freely, but one thought filled him--the natural desire of self-preservation. What could he do? for it would be impossible to hang on long like that. He looked up stream, but he could see naught but water, and the flood was out widely on both sides. But the regular bank of the river must be beneath him, and the only chance seemed to be to climb up into the ragged top of the willow to whose pendent boughs he clung: a poor kind of refuge, but safety till the water sank.
