A great mass of foam got him in the face and filled his mouth with water and blinded him. Then he went under altogether for a few seconds， and when he came up again he was in quite another part of the Pool. Then the swirl caught him and carried him round and round and faster and faster till it took him right under the waterfall itself， and the force of the water plunged him down， deep down， so that he thought he would never be able to hold his breath till he came up again. And when he had come up and when at last he got somewhere near the thing he was trying to catch， it sailed away from him till it too got under the fall and was forced down to the bottom. When it came up again it was further from him than ever.
But at last， when he was almost tired to death， and bruised all over and numb with cold， he succeeded in gripping the thing with his teeth. And out he came carrying it in front of him and getting his front hoofs tangled up in it， for it was as big as a large hearthrug， and it was very heavy and cold and slimy.
