Tarzan had estimated the lion's distance down the valley and the distance that lay between himself and the forest, and had guessed that he would reach the trees before their paths crossed. He was not hunting for Numa the lion, and with the natural caution of the wild beast, he would avoid an encounter.
The mingled odors of a camp grew stronger in his nostrils, the scents of horses and men and food and smoke.
To you or to me, alone in a savage wilderness, engulfed in darkness, cognizant of the near approach of a hunting lion, these odors would have been most welcome. Tarzan's reaction to them was that of the wild beast that knows man only as an enemy—his muscles tensed as he smothered a low growl.
As he reached the edge of the forest, Numa was but a short distance to his right and approaching, so the ape-man took to the trees, through which he swung silently to the camp of the Shiftas.
Below him he saw a band of some twenty men with their horses and equipment. A rude boma of branches and brush had been erected about the camp site as a partial protection against wild beasts, but more dependence was evidently placed upon the fire which they kept burning in the center of the camp.
In a single quick glance the ape-man took in the details of the scene below him, and then his eyes came to rest upon the only one that aroused either interest or curiosity, a white man who lay securely bound a short distance from the fire.
Ordinarily, Tarzan was no more concerned by the fate of a white man than by that of a black man or any other created thing to which he was not bound by ties of friendship. But in this instance there were two factors that made the life of the captive a matter of interest to the Lord of the Jungle. First, and probably predominant, was his desire to be further avenged upon the Shiftas; the second was curiosity, for the white man that lay bound below him was different from any that he had seen before.
His only garment appeared to be a habergeon made up of ivory discs that partially overlay one another, unless certain ankle, wrist, neck, and head ornaments might have been considered to possess such utilitarian properties as to entitle them to a similar classification. Except for these, his arms and legs were naked. His head rested upon the ground with the face turned away from Tarzan so that the ape-man could not see his features but only that his hair was heavy and black.
As he watched the camp, seeking for some suggestion as to how he might most annoy or inconvenience the bandits, it occurred to Tarzan that a just reprisal would consist in taking from them something that they wanted, just as they had deprived him of the buck he had desired. Evidently they wished the prisoner very much or they would not have gone to the trouble of securing him so carefully, so this fact decided Tarzan to steal the white man from them.
To accomplish his design, he decided to wait until the camp slept, and settling himself comfortably in a crotch of the tree, he prepared to keep his vigil with the tireless patience of the hunting beast he was. As he watched, he saw several of the Shiftas attempt to communicate with their prisoner, but it was evident that neither understood the other.
Tarzan was familiar with the language spoken by the Kafichos and Gallos, and the questions that they put to their prisoner aroused his curiosity still further. There was one question that they asked him in many different ways, in several dialects, and in sign which the captive either did not understand or pretended not to. Tarzan was inclined to believe that the latter was true, for the sign language was such that it could scarcely be misunderstood. They were asking him the way to a place where there was much ivory and gold, but they got no information from him.
"The pig understands us well enough," growled one of the Shiftas; "he is just pretending that he does not."
"If he won't tell us, what is the use of carrying him around with us and feeding him?" demanded another. "We might as well kill him now."
"We will let him think it over tonight," replied one who was evidently the leader, "and if he still refuses to speak in the morning, we will kill him then."
This decision they attempted to transmit to the prisoner both by words and signs, and then they squatted about the fire and discussed the occurrences of the day and their plans for the future. The principal topic of their conversation was the strange white giant who had slain three of their number and had escaped upon one of their horses. After this had been debated thoroughly and in detail for some time, and the three survivors of the encounter had boasted severally of their deeds of valor, they withdrew to the rude shelters they had constructed and left the night to Tarzan, Numa, and a single sentry.
The silent watcher among the shadows of the tree waited on in patience until the camp should be sunk in deepest slumber and, waiting, planned the stroke that was to rob the Shiftas of their prey and satisfy his own desire for revenge.
At last the ape-man felt that the time had come when he might translate his plan into action; all but the sentry were wrapped in slumber, and even he was dozing beside the fire. As noiselessly as the shadow of a shadow, Tarzan descended from the tree, keeping well in the shadow cast by the fire.
For a moment he stood in silence, listening. He heard the breathing of Numa, in the darkness beyond the circle of firelight, and knew that the king of beasts was near and watching. Then he looked from behind the great bole of the tree and saw that the sentry's back was still turned toward him. Silently he moved into the open; stealthily, on soundless feet, he crept toward the unsuspecting bandit. He saw the matchlock across the fellow's knees: and for it he had respect, as have all jungle animals that have been hunted.
Closer and closer he came to his prey. At last he crouched directly behind him. There must be no noise, no outcry. Tarzan waited. Beyond the rim of fire waited Numa, expectant, for he saw that very gradually the flames were diminishing. A bronzed hand shot quickly forward; fingers of steel gripped the brown throat of the sentry almost at the instant that a knife was driven from below his left shoulder blade into his heart. The sentry was dead without knowing that death threatened him.
Tarzan withdrew the knife from the limp body and wiped the blade upon the once white robe of his victim; then he moved softly toward the prisoner who was lying in the open. For him, they had not bothered to build a shelter. As he made his way toward the man, Tarzan passed close to two of the shelters in which lay members of the band, but he made no noise that might awaken them. When he approached the captive more closely, he saw in the diminishing light of the fire that the man's eyes were open and that he was regarding Tarzan with level, though questioning, gaze. The ape-man put a finger to his lips to enjoin silence, and then he came and knelt beside the man and cut the thongs that secured his wrists and ankles. He helped him to his feet, for the thongs had been drawn tightly, and his legs were numb.
For a moment he waited while the stranger tested his feet and moved them rapidly in an effort to restore circulation; then he beckoned him to follow, and all would have been well but for Numa the lion. At this moment, either to voice his anger against the flames or to terrify the horses into a stampede, he elected to voice a thunderous roar.
So close was the lion that the sudden shattering of the deep silence of the night startled every sleeper to wakefulness. A dozen men seized their matchlocks and leaped from their shelters. In the waning light of the fire they saw no lion, but they saw their liberated captive, and they saw Tarzan of the Apes standing beside him.
