His journey across the plain was interrupted by the discovery of a small herd of antelope in a little swale, where the cover and the wind were well combined to make stalking easy. A fat yearling rewarded a half hour of stealthy creeping and a sudden, savage rush, and it was late in the afternoon when the ape-man settled himself upon his haunches beside his kill to enjoy the fruits of his skill, his cunning, and his prowess.

His hunger satisfied, thirst next claimed his attention. The river lured him by the shortest path toward its refreshing waters, and when he had drunk, night already had fallen and he was some half mile or more down stream from the point where he had seen the pile of yellow ingots, and where he hoped to meet the memory woman, or find some clew to her whereabouts or her identity.

To the jungle bred, time is usually a matter of small moment, and haste, except when engendered by terror, by rage, or by hunger, is distasteful. Today was gone. Therefore tomorrow, of which there was an infinite procession, would answer admirably for Tarzan’s further quest. And, besides, the ape-man was tired and would sleep.

A tree afforded him the safety, seclusion and comforts of a well-appointed bedchamber, and to the chorus of the hunters and the hunted of the wild river bank he soon dropped off into deep slumber.

Morning found him both hungry and thirsty again, and dropping from his tree he made his way to the drinking place at the river’s edge. There he found Numa, the lion, ahead of him. The big fellow was lapping the water greedily, and at the approach of Tarzan along the trail in his rear, he raised his head, and turning his gaze backward across his maned shoulders glared at the intruder. A low growl of warning rumbled from his throat; but Tarzan, guessing that the beast had but just quitted his kill and was well filled, merely made a slight detour and continued to the river, where he stopped a few yards above the tawny cat, and dropping upon his hands and knees plunged his face into the cool water. For a moment the lion continued to eye the man; then he resumed his drinking, and man and beast quenched their thirst side by side each apparently oblivious of the other’s presence.

Numa was the first to finish. Raising his head, he gazed across the river for a few minutes with that stony fixity of attention which is a characteristic of his kind. But for the ruffling of his black mane to the touch of the passing breeze he might have been wrought from golden bronze, so motionless, so statuesque his pose.

A deep sigh from the cavernous lungs dispelled the illusion. The mighty head swung slowly around until the yellow eyes rested upon the man. The bristled lip curved upward, exposing yellow fangs. Another warning growl vibrated the heavy jowls, and the king of beasts turned majestically about and paced slowly up the trail into the dense reeds.

Tarzan of the Apes drank on, but from the corners of his gray eyes he watched the great brute’s every move until he had disappeared from view, and, after, his keen ears marked the movements of the carnivore.

A plunge in the river was followed by a scant breakfast of eggs which chance discovered to him, and then he set off up river toward the ruins of the bungalow where the golden ingots had marked the center of yesterday’s battle.

And when he came upon the spot, great was his surprise and consternation, for the yellow metal had disappeared. The earth, trampled by the feet of horses and men, gave no clew. It was as though the ingots had evaporated into thin air.
