The strength of the current did not seem to be so powerful as I had judged it. However, its determination was difficult. The horse swam with great ease, but he was an extraordinary horse, with a capacity for doing with this apparent ease everything which it pleased him to attempt. I do not know whether this arose from the stirring of larger powers ordinarily latent, or whether the horse's manner somehow concealed the amount of the effort. I think the former is more probable.
Half-way across the river, we were not more than twenty yards down-stream from the ferry landing. Ump shouted to turn down into the eddy, and I swung El Mahdi around. A dozen long strokes brought us into the almost quiet water of the great rim to this circle, a circle that was a hundred yards in diameter, in which the water moved from the circumference to the centre with a velocity increasing with the contracting of its orbit, from almost dead water in its rim to a whirling eddy in its centre.
I pulled El Mahdi up and let him drift with the motion of the water. We swung slowly around the circle, moving inward so gently that our progress was almost imperceptible.
The panic of men carried out in flood water can be easily understood. The activity of any power is very apt to alarm when that power is controlled by no intelligence. It is the unthinking nature of the force that strikes the terror. Death and the dark would lose much if they lost this attribute. The water bubbled over the saddle. The horse drifted like a chip. To my eyes, a few feet above this flood, the water seemed to lift on all sides, not unlike the sloping rim of some enormous yellow dish, in which I was moving gradually to the centre.
