Here was something that should be looked into. If the band were on the march, he need not concern himself about them, but if they were permanently located in this district, that was a different matter. Tarzan expected to be here for some time, and it was well to know the nature, the number, and the location of all enemies.

Returning to the dyer, Tarzan crossed it and took up the plain trail of the Shifias. It led him up and down across some low hills and then down into the narrow valley of the stream that he had crossed farther up. Here the floor of the valley was forested, the river winding through the wood. Into this wood the trail led.

It was almost dark now; the brief equatorial twilight was rapidly fading into night. The nocturnal life of the forest and the hills was awakening, and from down among the deepening shadows of the valley came the coughing grunts of a hunting lion. Tarzan sniffed the warm air rising from the valley toward the mountains; it carried with it the odours of a camp and the scent spoor of man. He raised his head, and from his deep chest rumbled a full-throated roar. Tarzan of the Apes was hunting, too.

In the gathering shadows he stood then, erect and silent, a lonely figure standing in solitary grandeur upon that desolate hillside. Swiftly the silent night enveloped him; his figure merged with the darkness that made hill and valley, river and forest one. Not until then did Tarzan move; then he stepped down on silent feet toward the forest. Now was every sense alert, for now the great cats would be hunting. Often his sensitive nostrils quivered as they searched the air. No slightest sound escaped his keen ears.

As he advanced, the man scent became stronger, guiding his steps. Nearer and nearer sounded the deep cough of the lion, but of Numa Tarzan had little fear at present, knowing that the great cat, being upwind, could not be aware of his presence. Doubtless Numa had heard the ape-man's roar, but he could not know that its author was approaching him.

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 odours 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 odours 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 centre 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 shtiftas; "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.
