It was just at dusk. The voices of great four-footed hunters rose now and again from various directions, and as the canyon afforded among its trees no comfortable retreat the ape-man shouldered the carcass of the deer and started downward onto the plain. At its opposite side rose lofty trees--a great forest which suggested to his practiced eye a mighty jungle. Toward this the ape-man bent his step, but when midway of the plain he discovered standing alone such a tree as best suited him for a night's abode, swung lightly to its branches and, presently, a comfortable resting place. Here he ate the flesh of Bara and when satisfied carried the balance of the carcass to the opposite side of the tree where he deposited it far above the ground in a secure place. Returning to his crotch he settled himself for sleep and in another moment the roars of the lions and the howlings of the lesser cats fell upon deaf ears. The usual noises of the jungle composed rather than disturbed the ape-man but an unusual sound, however imperceptible to the awakened ear of civilized man, seldom failed to impinge upon the consciousness of Tarzan, however deep his slumber, and so it was that when the moon was high a sudden rush of feet across the grassy carpet in the vicinity of his tree brought him to alert and ready activity. Tarzan does not awaken as you and I with the weight of slumber still upon his eyes and brain, for did the creatures of the wild awaken thus, their awakenings would be few. As his eyes snapped open, clear and bright, so, clear and bright upon the nerve centers of his brain, were registered the various perceptions of all his senses. Almost beneath him, racing toward his tree was what at first glance appeared to be an almost naked white man, yet even at the first instant of discovery the long, white tail projecting rearward did not escape the ape-man. Behind the fleeing figure, escaping, came Numa, the lion, in full charge. Voiceless the prey, voiceless the killer; as two spirits in a dead world the two moved in silent swiftness toward the culminating tragedy of this grim race. Even as his eyes opened and took in the scene beneath him--even in that brief instant of perception, followed reason, judgment, and decision, so rapidly one upon the heels of the other that almost simultaneously the ape-man was in mid-air, for he had seen a white-skinned creature cast in a mold similar to his own, pursued by Tarzan's hereditary enemy. So close was the lion to the fleeing man-thing that Tarzan had no time carefully to choose the method of his attack. As a diver leaps from the springboard headforemost into the waters beneath, so Tarzan of the Apes dove straight for Numa, the lion; naked in his right hand the blade of his father that so many times before had tasted the blood of lions.
