I clamped my legs to the horse, held my breath, and went down in the saddle. I thought we should never reach the bottom of that river. The current tugged, trying to pull me loose and whirl me away. The horse under me felt like a millstone. The weight of water pressed like some tremendous thumb. Then we struck the rock bottom and began to come up. The sensation changed. I seemed now to be thrust violently from below against a weight pressing on my head, as though I were being used by some force under me to drive the containing cork out of the bottle in which we were enclosed. I began to be troubled for breath, my head rang. The distance seemed interminable. Then we popped up on the top of the river, and I filled with the blessed air to the very tips of my fingers.
The horse blew the water out of his nostrils and doubled his long legs. I thought he was going down again, and, seizing the top of the saddle horn, I loosed my feet in the stirrups. If El Mahdi returned to the deeps of that river, he would go by himself.
He stretched out his grey neck, sank until the water came running over the saddle, and then began to swim with long, graceful strokes of his iron legs as though it were the easiest thing in the world.
