His glittering eyes remained fixed upon Rabba Kega after acknowledging the presence of the winged torture by a single glance. He heard and followed the movements of the insect with his keen ears, and then he felt it alight upon his forehead. No muscle twitched, for the muscles of such as he are the servants of the brain.
Down across his face crept the horrid thing--over nose and lips and chin. Upon his throat it paused, and turning, retraced its steps. Tarzan watched Rabba Kega.
Now not even his eyes moved. So motionless he crouched that only death might counterpart his movelessness.
The insect crawled upward over the nut-brown cheek and stopped with its antennae brushing the lashes of his lower lid.
You or I would have started back, closing our eyes and striking at the thing; but you and I are the slaves, not the masters of our nerves. Had the thing crawled upon the eyeball of the ape-man, it is believable that he could yet have remained wide-eyed and rigid; but it did not.
For a moment it loitered there close to the lower lid, then it rose and buzzed away.
Down toward Rabba Kega it buzzed and the black man heard it, saw it, struck at it, and was stung upon the cheek before he killed it. Then he rose with a howl of pain and anger, and as he turned up the trail toward the village of Mbonga, the chief, his broad, black back was exposed to the silent thing waiting above him.
And as Rabba Kega turned, a lithe figure shot outward and downward from the tree above upon his broad shoulders.
The impact of the springing creature carried Rabba Kega to the ground. He felt strong jaws close upon his neck, and when he tried to scream, steel fingers throttled his throat.
The powerful black warrior struggled to free himself;but he was as a child in the grip of his adversary.
Presently Tarzan released his grip upon the other's throat;but each time that Rabba Kega essayed a scream, the cruel fingers choked him painfully. At last the warrior desisted.
Then Tarzan half rose and kneeled upon his victim's back, and when Rabba Kega struggled to arise, the ape-man pushed his face down into the dirt of the trail.
With a bit of the rope that had secured the kid, Tarzan made Rabba Kega's wrists secure behind his back, then he rose and jerked his prisoner to his feet, faced him back along the trail and pushed him on ahead.
Not until he came to his feet did Rabba Kega obtain a square look at his assailant. When he saw that it was the white devil-god his heart sank within him and his knees trembled; but as he walked along the trail ahead of his captor and was neither injured nor molested his spirits slowly rose, so that he took heart again.
Possibly the devil-god did not intend to kill him after all.
Had he not had little Tibo in his power for days without harming him, and had he not spared Momaya, Tibo's mother, when he easily might have slain her?
And then they came upon the cage which Rabba Kega, with the other black warriors of the village of Mbonga, the chief, had placed and baited for Numa. Rabba Kega saw that the bait was gone, though there was no lion within the cage, nor was the door dropped. He saw and he was filled with wonder not unmixed with apprehension.
It entered his dull brain that in some way this combination of circumstances had a connection with his presence there as the prisoner of the white devil-god.
Nor was he wrong. Tarzan pushed him roughly into the cage, and in another moment Rabba Kega understood.
Cold sweat broke from every pore of his body--he trembled as with ague--for the ape-man was binding him securely in the very spot the kid had previously occupied.
The witch-doctor pleaded, first for his life, and then for a death less cruel; but he might as well have saved his pleas for Numa, since already they were directed toward a wild beast who understood no word of what he said.
But his constant jabbering not only annoyed Tarzan, who worked in silence, but suggested that later the black might raise his voice in cries for succor, so he stepped out of the cage, gathered a handful of grass and a small stick and returning, jammed the grass into Rabba Kega's mouth, laid the stick crosswise between his teeth and fastened it there with the thong from Rabba Kega's loin cloth.
Now could the witch-doctor but roll his eyes and sweat.
Thus Tarzan left him.
The ape-man went first to the spot where he had cached the body of the kid. Digging it up, he ascended into a tree and proceeded to satisfy his hunger. What remained he again buried; then he swung away through the trees to the water hole, and going to the spot where fresh, cold water bubbled from between two rocks, he drank deeply.
The other beasts might wade in and drink stagnant water;but not Tarzan of the Apes. In such matters he was fastidious.
From his hands he washed every trace of the repugnant scent of the Gomangani, and from his face the blood of the kid. Rising, he stretched himself not unlike some huge, lazy cat, climbed into a near-by tree and fell asleep.
When he awoke it was dark, though a faint luminosity still tinged the western heavens. A lion moaned and coughed as it strode through the jungle toward water. It was approaching the drinking hole. Tarzan grinned sleepily, changed his position and fell asleep again.
When the blacks of Mbonga, the chief, reached their village they discovered that Rabba Kega was not among them.
When several hours had elapsed they decided that something had happened to him, and it was the hope of the majority of the tribe that whatever had happened to him might prove fatal. They did not love the witch-doctor. Love and fear seldom are playmates; but a warrior is a warrior, and so Mbonga organized a searching party. That his own grief was not unassuagable might have been gathered from the fact that he remained at home and went to sleep.
