At that he lay down upon the ground, but it was evident he had no intention of going to sleep.

He had shown little or no emotion on hearing of his brother's death. There was black blood in his veins, and, with the more savage races, death is a simple and everyday affair. For all that, there is no reason to suppose that he did not feel the great loss he had sustained.

A long time elapsed before Harry, too, was able to sleep. And, when at last he did so, he was for ever struggling on the brink of an unfathomable abyss, so that he was little rested when at daybreak he was awakened by Cortes.

When he judged that they were parallel to the place where the tragedy had happened, they crossed the stream and walked straight for the cliff.

At the foot of the precipice was a kind of terrace, upon which grew scattered trees, about the roots of one of which were boulders. Lying on his back, across one of these rocks, they found the body of the Black Dog of the Cameroons.
