Chulk eyed the pouch, which, suspended over Mugambi’s shoulder, swung beside his black hip. This took his fancy, for it was ornamented with feathers and a fringe, and so the ape hung about Mugambi’s boma, waiting an opportunity to seize either by stealth or might some object of the black’s apparel.

Nor was it long before the opportunity came. Feeling safe within his thorny enclosure, Mugambi was wont to stretch himself in the shade of his shelter during the heat of the day, and sleep in peaceful security until the declining sun carried with it the enervating temperature of midday.

Watching from above, Chulk saw the black warrior stretched thus in the unconsciousness of sleep one sultry afternoon. Creeping out upon an overhanging branch the anthropoid dropped to the ground within the boma. He approached the sleeper upon padded feet which gave forth no sound, and with an uncanny woodcraft that rustled not a leaf or a grass blade.

Pausing beside the man, the ape bent over and examined his belongings. Great as was the strength of Chulk there lay in the back of his little brain a something which deterred him from arousing the man to combat—a sense that is inherent in all the lower orders, a strange fear of man, that rules even the most powerful of the jungle creatures at times.

To remove Mugambi’s loin cloth without awakening him would be impossible, and the only detachable things were the knob-stick and the pouch, which had fallen from the black’s shoulder as he rolled in sleep.

Seizing these two articles, as better than nothing at all, Chulk retreated with haste, and every indication of nervous terror, to the safety of the tree from which he had dropped, and, still haunted by that indefinable terror which the close proximity of man awakened in his breast, fled precipitately through the jungle. Aroused by attack, or supported by the presence of another of his kind, Chulk could have braved the presence of a score of human beings, but alone—ah, that was a different matter—alone, and unenraged.

It was some time after Mugambi awoke that he missed the pouch. Instantly he was all excitement. What could have become of it? It had been at his side when he lay down to sleep—of that he was certain, for had he not pushed it from beneath him when its bulging bulk, pressing against his ribs, caused him discomfort? Yes, it had been there when he lay down to sleep. How then had it vanished?

Mugambi’s savage imagination was filled with visions of the spirits of departed friends and enemies, for only to the machinations of such as these could he attribute the disappearance of his pouch and knob-stick in the first excitement of the discovery of their loss; but later and more careful investigation, such as his woodcraft made possible, revealed indisputable evidence of a more material explanation than his excited fancy and superstition had at first led him to accept.

In the trampled turf beside him was the faint impress of huge, manlike feet. Mugambi raised his brows as the truth dawned upon him. Hastily leaving the boma he searched in all directions about the enclosure for some further sign of the tell-tale spoor. He climbed trees and sought for evidence of the direction of the thief’s flight; but the faint signs left by a wary ape who elects to travel through the trees eluded the woodcraft of Mugambi. Tarzan might have followed them; but no ordinary mortal could perceive them, or perceiving, translate.

The black, now strengthened and refreshed by his rest, felt ready to set out again for Waziri, and finding himself another knob-stick, turned his back upon the river and plunged into the mazes of the jungle.
