Now he worked at skinning the six pigs and his eyes and his fingers worked as though there was naught else in all the world than these six carcasses; but his ears and his nose were as busily engaged elsewhere—the former ranging the forest all about and the latter assaying each passing zephyr. It was his nose that first discovered the approach of Sabor, the lioness, when the wind shifted for a moment.

As clearly as though he had seen her with his eyes, Tarzan knew that the lioness had caught the scent of the freshly killed pigs and immediately had moved down wind in their direction. He knew from the strength of the scent spoor and the rate of the wind about how far away she was and that she was approaching from behind him. He was finishing the last pig and he did not hurry. The five pelts lay close at hand-he had been careful to keep them thus together and near him—an ample tree waved its low branches above him.

He did not even turn his head for he knew she was not yet in sight; but he bent his ears just a bit more sharply for the first sound of her nearer approach. When the final skin had been removed he rose. Now he heard Sabor in the bushes to his rear, but not yet too close. Leisurely he gathered up the six pelts and one of the carcasses, and as the lioness appeared between the boles of two trees he swung upward into the branches above him. Here he hung the hides over a limb, seated himself comfortably upon another with his back against the bole of the tree, cut a hind quarter from the carcass he had carried with him and proceeded to satisfy his hunger. Sabor slunk, growling, from the brush, cast a wary eye upward toward the ape-man and then fell upon the nearest carcass.

Tarzan looked down upon her and grinned, recalling an argument he had once had with a famous big-game hunter who had declared that the king of beasts ate only what he himself had killed. Tarzan knew better for he had seen Numa and Sabor stoop even to carrion.

Having filled his belly, the ape-man fell to work upon the hides—all large and strong. First he cut strips from them about half an inch wide. When he had sufficient number of these strips he sewed two of the hides together, afterwards piercing holes every three or four inches around the edges. Running another strip through these holes gave him a large bag with a drawstring. In similar fashion he produced four other like bags, but smaller, from the four remaining hides and had several strips left over.

All this done he threw a large, juicy fruit at Sabor, cached the remainder of the pig in a crotch of the tree and swung off toward the southwest through the middle terraces of the forest, carrying his five bags with him. Straight he went to the rim of the gulch where he had imprisoned Numa, the lion. Very stealthily he approached the edge and peered over. Numa was not in sight. Tarzan sniffed and listened. He could hear nothing, yet he knew that Numa must be within the cave. He hoped that he slept—much depended upon Numa not discovering him.

Cautiously he lowered himself over the edge of the cliff, and with utter noiselessness commenced the descent toward the bottom of the gulch. He stopped often and turned his keen eyes and ears in the direction of the cave's mouth at the far end of the gulch, some hundred feet away. As he neared the foot of the cliff his danger increased greatly. If he could reach the bottom and cover half the distance to the tree that stood in the center of the gulch he would feel comparatively safe for then, even if Numa appeared, he felt that he could beat him either to the cliff or to the tree, but to scale the first thirty feet of the cliff rapidly enough to elude the leaping beast would require a running start of at least twenty feet as there were no very good hand- or footholds close to the bottom—he had had to run up the first twenty feet like a squirrel running up a tree that other time he had beaten an infuriated Numa to it. He had no desire to attempt it again unless the conditions were equally favorable at least, for he had escaped Numa's raking talons by only a matter of inches on the former occasion.

At last he stood upon the floor of the gulch. Silent as a disembodied spirit he advanced toward the tree. He was half way there and no sign of Numa. He reached the scarred bole from which the famished lion had devoured the bark and even torn pieces of the wood itself and yet Numa had not appeared. As he drew himself up to the lower branches he commenced to wonder if Numa were in the cave after all. Could it be possible that he had forced the barrier of rocks with which Tarzan had plugged the other end of the passage where it opened into the outer world of freedom? Or was Numa dead? The ape-man doubted the verity of the latter suggestion as he had fed the lion the entire carcasses of a deer and a hyena only a few days since—he could not have starved in so short a time, while the little rivulet running across the gulch furnished him with water a-plenty.

Tarzan started to descend and investigate the cavern when it occurred to him that it would save effort were he to lure Numa out instead.
