Tarzan wondered how it had survived at all. He tried to teach it, and found a ray of hope in the fact that Go-bu-balu had mastered a few words of the language of the anthropoids, and that he could now cling to a high-tossed branch without screaming in fear; but there was something about the child which worried Tarzan.
He often had watched the blacks within their village.
He had seen the children playing, and always there had been much laughter; but little Go-bu-balu never laughed.
It was true that Tarzan himself never laughed. Upon occasion he smiled, grimly, but to laughter he was a stranger.
The black, however, should have laughed, reasoned the ape-man.
It was the way of the Gomangani.
Also, he saw that the little fellow often refused food and was growing thinner day by day. At times he surprised the boy sobbing softly to himself. Tarzan tried to comfort him, even as fierce Kala had comforted Tarzan when the ape-man was a balu, but all to no avail.
Go-bu-balu merely no longer feared Tarzan--that was all.
He feared every other living thing within the jungle.
He feared the jungle days with their long excursions through the dizzy tree tops. He feared the jungle nights with their swaying, perilous couches far above the ground, and the grunting and coughing of the great carnivora prowling beneath him.
Tarzan did not know what to do. His heritage of English blood rendered it a difficult thing even to consider a surrender of his project, though he was forced to admit to himself that his balu was not all that he had hoped.
Though he was faithful to his self-imposed task, and even found that he had grown to like Go-bu-balu, he could not deceive himself into believing that he felt for it that fierce heat of passionate affection which Teeka revealed for Gazan, and which the black mother had shown for Go-bu-balu.
The little black boy from cringing terror at the sight of Tarzan passed by degrees into trustfulness and admiration.
Only kindness had he ever received at the hands of the great white devil-god, yet he had seen with what ferocity his kindly captor could deal with others. He had seen him leap upon a certain he-ape which persisted in attempting to seize and slay Go-bu-balu. He had seen the strong, white teeth of the ape-man fastened in the neck of his adversary, and the mighty muscles tensed in battle.
He had heard the savage, bestial snarls and roars of combat, and he had realized with a shudder that he could not differentiate between those of his guardian and those of the hairy ape.
He had seen Tarzan bring down a buck, just as Numa, the lion, might have done, leaping upon its back and fastening his fangs in the creature's neck. Tibo had shuddered at the sight, but he had thrilled, too, and for the first time there entered his dull, Negroid mind a vague desire to emulate his savage foster parent. But Tibo, the little black boy, lacked the divine spark which had permitted Tarzan, the white boy, to benefit by his training in the ways of the fierce jungle. In imagination he was wanting, and imagination is but another name for super-intelligence.
Imagination it is which builds bridges, and cities, and empires. The beasts know it not, the blacks only a little, while to one in a hundred thousand of earth's dominant race it is given as a gift from heaven that man may not perish from the earth.
While Tarzan pondered his problem concerning the future of his balu, Fate was arranging to take the matter out of his hands. Momaya, Tibo's mother, grief-stricken at the loss of her boy, had consulted the tribal witch-doctor, but to no avail. The medicine he made was not good medicine, for though Momaya paid him two goats for it, it did not bring back Tibo, nor even indicate where she might search for him with reasonable assurance of finding him.
Momaya, being of a short temper and of another people, had little respect for the witch-doctor of her husband's tribe, and so, when he suggested that a further payment of two more fat goats would doubtless enable him to make stronger medicine, she promptly loosed her shrewish tongue upon him, and with such good effect that he was glad to take himself off with his zebra's tail and his pot of magic.
When he had gone and Momaya had succeeded in partially subduing her anger, she gave herself over to thought, as she so often had done since the abduction of her Tibo, in the hope that she finally might discover some feasible means of locating him, or at least assuring herself as to whether he were alive or dead.
It was known to the blacks that Tarzan did not eat the flesh of man, for he had slain more than one of their number, yet never tasted the flesh of any. Too, the bodies always had been found, sometimes dropping as though from the clouds to alight in the center of the village.
As Tibo's body had not been found, Momaya argued that he still lived, but where?
Then it was that there came to her mind a recollection of Bukawai, the unclean, who dwelt in a cave in the hillside to the north, and who it was well known entertained devils in his evil lair. Few, if any, had the temerity to visit old Bukawai, firstly because of fear of his black magic and the two hyenas who dwelt with him and were commonly known to be devils masquerading, and secondly because of the loathsome disease which had caused Bukawai to be an outcast--a disease which was slowly eating away his face.
Now it was that Momaya reasoned shrewdly that if any might know the whereabouts of her Tibo, it would be Bukawai, who was in friendly intercourse with gods and demons, since a demon or a god it was who had stolen her baby;but even her great mother love was sorely taxed to find the courage to send her forth into the black jungle toward the distant hills and the uncanny abode of Bukawai, the unclean, and his devils.
