Before she had undone the knot the others were a fair distance ahead. By the time she had got the stone out and was putting the shoe on again she could no longer hear them. But almost at once she heard something else. It was not coming from the direction of the house.
What she heard was a thumping. It sounded as if dozens of strong workmen were hitting the ground as hard as they could with great wooden mallets. And it was very quickly coming nearer. She was already sitting with her back to a tree， and as the tree was not one she could climb， there was really nothing to do but to sit dead still and press herself against the tree and hope she wouldn‘t be seen.
Thump， thump， thump . . . and whatever it was must be very close now for she could feel the ground shaking. But she could see nothing. She thought the thing.or things.must be just behind her. But then there came a thump on the path right in front of her. She knew it was on the path not only by the sound but because she saw the sand scatter as if it had been struck a heavy blow. But she could see nothing that had struck it. Then all the thumping noises drew together about twenty feet away from her and suddenly ceased. Then came the Voice.
