The panther had taken to a large tree as Tarzan came within sight of him, and beyond and below him Tarzan saw the tribe of Akut lolling in a little, natural clearing. Some of them were dozing against the boles of trees, while others roamed about turning over bits of bark from beneath which they transferred the luscious grubs and beetles to their mouths. Akut was the closest to Sheeta. The great cat lay crouched upon a thick limb, hidden from the ape’s view by dense foliage, waiting patiently until the anthropoid should come within range of his spring. Tarzan cautiously gained a position in the same tree with the panther and a little above him. In his left hand he grasped his slim stone blade. He would have preferred to use his noose, but the foliage surrounding the huge cat precluded the possibility of an accurate throw with the rope. Akut had now wandered quite close beneath the tree wherein lay the waiting death. Sheeta slowly edged his hind paws along the branch still further beneath him, and then with a hideous shriek he launched himself toward the great ape. The barest fraction of a second before his spring another beast of prey above him leaped, its weird and savage cry mingling with his. As the startled Akut looked up he saw the panther almost above him, and already upon the panther’s back the white ape that had bested him that day near the great water. The teeth of the ape-man were buried in the back of Sheeta’s neck and his right arm was round the fierce throat, while the left hand, grasping a slender piece of stone, rose and fell in mighty blows upon the panther’s side behind the left shoulder. Akut had just time to leap to one side to avoid being pinioned beneath these battling monsters of the jungle. With a crash they came to earth at his feet. Sheeta was screaming, snarling, and roaring horribly; but the white ape clung tenaciously and in silence to the thrashing body of his quarry. Steadily and remorselessly the stone knife was driven home through the glossy hide—time and again it drank deep, until with a final agonized lunge and shriek the great feline rolled over upon its side and, save for the spasmodic jerking of its muscles, lay quiet and still in death. Then the ape-man raised his head, as he stood over the carcass of his kill, and once again through the jungle rang his wild and savage victory challenge. Akut and the apes of Akut stood looking in startled wonder at the dead body of Sheeta and the lithe, straight figure of the man who had slain him. Tarzan was the first to speak. He had saved Akut’s life for a purpose, and, knowing the limitations of the ape intellect, he also knew that he must make this purpose plain to the anthropoid if it were to serve him in the way he hoped.
