But now that Rokoff had succeeded in chasing them far inland, up the savage river, there could be little doubt but that he would eventually overhaul them, unless, as was still more probable, they should be captured and killed by the very cannibals farther up the Ugambi, to whom, Tarzan was now convinced, it had been Rokoff’s intention to deliver the baby.

As he talked to Kaviri the canoes had been moving steadily up-river toward the chief’s village. Kaviri’s warriors plied the paddles in the three canoes, casting sidelong, terrified glances at their hideous passengers. Three of the apes of Akut had been killed in the encounter, but there were, with Akut, eight of the frightful beasts remaining, and there was Sheeta, the panther, and Tarzan and Mugambi.

Kaviri’s warriors thought that they had never seen so terrible a crew in all their lives. Momentarily they expected to be pounced upon and torn asunder by some of their captors; and, in fact, it was all that Tarzan and Mugambi and Akut could do to keep the snarling, ill-natured brutes from snapping at the glistening, naked bodies that brushed against them now and then with the movements of the paddlers, whose very fear added incitement to the beasts.

At Kaviri’s camp Tarzan paused only long enough to eat the food that the blacks furnished, and arrange with the chief for a dozen men to man the paddles of his canoe.

Kaviri was only too glad to comply with any demands that the ape-man might make if only such compliance would hasten the departure of the horrid pack; but it was easier, he discovered, to promise men than to furnish them, for when his people learned his intentions those that had not already fled into the jungle proceeded to do so without loss of time, so that when Kaviri turned to point out those who were to accompany Tarzan, he discovered that he was the only member of his tribe left within the village.

Tarzan could not repress a smile.

“They do not seem anxious to accompany us,” he said; “but just remain quietly here, Kaviri, and presently you shall see your people flocking to your side.”

Then the ape-man rose, and, calling his pack about him, commanded that Mugambi remain with Kaviri, and disappeared in the jungle with Sheeta and the apes at his heels.

For half an hour the silence of the grim forest was broken only by the ordinary sounds of the teeming life that but adds to its lowering loneliness. Kaviri and Mugambi sat alone in the palisaded village, waiting.

Presently from a great distance came a hideous sound. Mugambi recognized the weird challenge of the ape-man. Immediately from different points of the compass rose a horrid semicircle of similar shrieks and screams, punctuated now and again by the blood-curdling cry of a hungry panther.
