DOLLY, quite tired out with pain, had sunk into a restless sleep; and Mr. and Mrs. Stanton were sitting on the rocks outside the door, waiting till Mr. Bradford should return, when a sweet, clear whistle, like a bird-call, rang through the wood. It was repeated again, and yet again, and was plainly some signal. Each time it came nearer, and at the third sounded close at hand; and the next instant Lem sprang round a point of the rock. As he caught sight of the lady and gentleman before the hovel door, he started, and, after staring at them for one instant, turned to run away.
