This opening was about forty feet from the ground, and ellipse-shaped.
It cannot have been more than twenty feet high by ten wide, and was partially hidden by ferns and bushes that grew about it in the surface of the cliff.

Keen as my eyes were, I doubt if I should ever have noticed it, for there were many such cracks and crannies in the rocky face of the great mountain.
We drew near and looked carefully at the place.

The first thing I noticed was that the rock, which was not quite perpendicular, had been worn by the continual passage of baboons; the second, that something white was hanging on a bush near the top of the ascent.
It was a pocket-handkerchief.
Now there was no more doubt about the matter.

With a beating heart I began the ascent.

For the first twenty feet it was comparatively easy, for the rock shelved; the next ten feet was very difficult, but still possible to an active man, and I achieved it, followed by Indaba-zimbi.
But the last twelve or fifteen feet could only be scaled by throwing a rope over the trunk of a stunted tree, which grew at the bottom of the opening.
