the bottom of the opening.  This we accomplished with some trouble, and the rest was easy.  A foot or two above my head the handkerchief fluttered in the wind.  Hanging to the rope, I grasped it.  It was my wife’s.  As I did so I noticed the face of a baboon peering at me over the edge of the cleft, the first baboon we had seen that morning.  The brute gave a bark and vanished.  Thrusting the handkerchief into my breast, I set my feet against the cliff and scrambled up as hard as I could go.  I knew that we had no time to lose, for the baboon would quickly alarm the others.  I gained the cleft.  It was a mere arched passage cut by water, ending in a gulley, which led to a wide open space of some sort.  I looked through the passage and saw that the gulley was black with baboons.  On they came by the hundred.  I unslung my elephant gun from my shoulders and waited, calling to the men below to come up with all possible speed.  The brutes streamed on down the gloomy gulf towards me, barking, grunting, and showing their huge teeth.  I waited till they were within fifteen yards.  Then I fired the elephant gun, which was loaded with slugs, right into the thick of them.  In that narrow place the report echoed like a cannon shot, but its sound was quickly swallowed in the volley of piercing human-sounding groans and screams that followed.  The charge of heavy slugs had ploughed through the host of baboons, of which at least a dozen lay dead or dying in the passage.  For a moment they hesitated, then they came on again with a hideous clamour.  Fortunately by this time Indaba-zimbi, who also had a gun, was standing by my side, otherwise I should have been torn to pieces before I could re-load.  He fired both barrels into them, and again checked the rush.  But they came on again, and notwithstanding the appearance of two other natives with guns, which they let off with more or less success, we should have been overwhelmed by the great and ferocious apes had I not by this time succeeded in re-loading the elephant gun.  When they were right on us, I fired, with even more deadly effect than before, for at that distance every slug told on their long line.  The howls and screams of pain and rage were now something inconceivable.  One might have thought that we were doing battle with a host of demons; indeed in that light—­for the overhanging arch of rock made it very dark—­the gnashing snouts and sombre glowing eyes of the apes looked like those of devils as they are represented by monkish fancy.  But the last shot was too much for them; they withdrew, dragging some of their wounded with them, and thus gave us time to get our men up the cliff.  In a few minutes all were there, and we advanced down the passage, which presently opened into a rocky gulley with shelving sides.  This gulley had a water-way at the bottom of it; it was about a hundred yards long, and the slopes on either side were topped by precipitous cliffs.  I looked at these slopes; they literally swarmed with baboons, grunting, barking, screaming, and beating their breasts with their long arms, in fury.  I looked up the water-way; along it, accompanied by a mob, or, as it were, a guard of baboons, ran Hendrika, her long hair flying, madness written on her face, and in her arms was the senseless form of little Tota.
