comfortable and dry. A tiny rivulet of cold water trickled outward from the opening.

Close to the cave Tarzan kneeled and sniffed the ground. A low growl escaped him and his upper lip curved to expose his fighting fangs. "Numa!" he muttered; but he did not stop. Numa might not be at home -- he would investigate. The entrance was so low that the ape-man was compelled to drop to all fours before he could poke his head within the aperture; but first he looked, listened, and sniffed in each direction at his rear -- he would not be taken by surprise from that quarter.

His first glance within the cave revealed a narrow tunnel with daylight at its farther end. The interior of the tunnel was not so dark but that the ape-man could readily see that it was untenanted at present. Advancing cautiously he crawled toward the opposite end imbued with a full realization of what it would mean if Numa should suddenly enter the tunnel in front of him; but Numa did not appear and the ape-man emerged at length into the open and stood erect, finding himself in a rocky cleft whose precipitous walls rose almost sheer on every hand, the tunnel from the gorge passing through the cliff and forming a passageway from the outer world into a large pocket or gulch entirely inclosed by steep walls of rock. Except for the small passageway from the gorge, there was no other entrance to the gulch which was some hundred feet in length and about fifty in width and appeared to have been worn from the rocky cliff by the falling of water during long ages. A tiny stream from Kilimanjaro's eternal snow cap still trickled over the edge of the rocky wall at the upper end of the gulch, forming a little pool at the bottom of the cliff from which a small rivulet wound downward to the tunnel through which it passed to the gorge beyond. A single great tree flourished near the center of the gulch, while tufts of wiry grass were scattered here and there among the rocks of the gravelly floor.

The bones of many large animals lay about and among them were several human skulls. Tarzan raised his eyebrows. "A man-eater," he murmured, "and from appearances he has held sway here for a long time. Tonight Tarzan will take the lair of the man-eater and Numa may roar and grumble upon the outside."

The ape-man had advanced well into the gulch as he investigated his surroundings and now as he stood near the tree, satisfied that the tunnel would prove a dry and quiet retreat for the night, he turned to retrace his way to the outer end of the entrance that he might block it with bowlders against Numa's return, but even with the thought there came something to his sensitive ears that froze him into statuesque immobility with eyes glued upon the tunnel's mouth. A moment later the head of a huge lion framed in a great black mane appeared in the opening. The yellow-green eyes glared, round and unblinking, straight at the trespassing Tarmangani, a low growl rumbled from the
