I watched it for some minutes--it never moved.

Several heads of hippopotami appeared and vanished in different directions, but the float was still; it marked the spot where the grand old bull lay dead beneath.
I shot another hippo, that I thought must be likewise dead; and, taking the time by my watch, I retired to the shade of a tree with Hassan, while Hadji Ali and the old hunter returned to camp for assistance in men and knives, etc.
In a little more than an hour and a half, two objects like the backs of turtles appeared above the surface.

These were the flanks of the two hippos.

A short time afterward the men arrived, and, regardless of crocodiles, they swam toward the bodies.

One was towed directly to the shore by the rope attached to the harpoon, the other was secured by a long line and dragged to the bank of clean pebbles.
