But none did so; instead, they drew away as he approached, and presently the whole pack moved off into the jungle, and Tarzan was left alone once more upon the beach.

The ape-man was sore from the wounds that Molak had inflicted upon him, but he was inured to physical suffering and endured it with the calm and fortitude of the wild beasts that had taught him to lead the jungle life after the manner of all those that are born to it.

His first need, he realized, was for weapons of offence and defence, for his encounter with the apes, and the distant notes of the savage voices of Numa the lion, and Sheeta, the panther, warned him that his was to be no life of indolent ease and security.

It was but a return to the old existence of constant bloodshed and danger—to the hunting and the being hunted. Grim beasts would stalk him, as they had stalked him in the past, and never would there be a moment, by savage day or by cruel night, that he might not have instant need of such crude weapons as he could fashion from the materials at hand.

Upon the shore he found an out-cropping of brittle, igneous rock. By dint of much labour he managed to chip off a narrow sliver some twelve inches long by a quarter of an inch thick. One edge was quite thin for a few inches near the tip. It was the rudiment of a knife.

With it he went into the jungle, searching until he found a fallen tree of a certain species of hardwood with which he was familiar. From this he cut a small straight branch, which he pointed at one end.

Then he scooped a small, round hole in the surface of the prostrate trunk. Into this he crumbled a few bits of dry bark, minutely shredded, after which he inserted the tip of his pointed stick, and, sitting astride the bole of the tree, spun the slender rod rapidly between his palms.

After a time a thin smoke rose from the little mass of tinder, and a moment later the whole broke into flame. Heaping some larger twigs and sticks upon the tiny fire, Tarzan soon had quite a respectable blaze roaring in the enlarging cavity of the dead tree.

Into this he thrust the blade of his stone knife, and as it became superheated he would withdraw it, touching a spot near the thin edge with a drop of moisture. Beneath the wetted area a little flake of the glassy material would crack and scale away.

Thus, very slowly, the ape-man commenced the tedious operation of putting a thin edge upon his primitive hunting-knife.
