is post so that at last Tarzan really
began to consider seriously if it might not be as well to take the
chance of a battle with him rather than remain longer cold and wet
and humiliated in the tree.

But even as he turned the matter over in his mind Numa turned
suddenly and walked majestically toward the tunnel without even a
backward glance. The instant that he disappeared, Tarzan dropped
lightly to the ground upon the far side of the tree and was away at
top speed for the cliff. The lion had no sooner entered the tunnel
than he backed immediately out again and, pivoting like a flash,
was off across the gulch in full charge after the flying ape-man;
but Tarzan's lead was too great--if he could find finger or foothold
upon the sheer wall he would be safe; but should he slip from the
wet rocks his doom was already sealed as he would fall directly into
Numa's clutches where even the Great Tarmangani would be helpless.

With the agility of a cat Tarzan ran up the cliff for thirty feet
before he paused, and there finding a secure foothold, he stopped
and looked down upon Numa who was leaping upward in a wild and
futile attempt to scale the rocky wall to his prey. Fifteen or
twenty feet from the ground the lion would scramble only to fall
backward again defeated. Tarzan eyed him for a moment and then
commenced a slow and cautious ascent toward the summit. Several
times he had difficulty in finding holds but at last he drew himself
over the edge, rose, picked up a bit of loose rock, hurled it at
Numa and strode away.

Finding an easy descent to the gorge, he was about to pursue his
journey in the direction of the still-booming guns when a sudden
thought caused him to halt and a half-smile to play about his lips.
Turning, he trotted quickly back to the outer opening of Numa's
tunnel. Close beside it he listened for a moment and then rapidly
began to gather large rocks and pile them within the entrance.
He had almost closed the aperture when the lion appeared upon the
inside--a very ferocious and angry lion that pawed and clawed at
the rocks and uttered mighty roars that caused the earth to tremble;
but roars did not frighten Tarzan of the Apes. At Kala's shaggy
breast he had closed his infant eyes in sleep upon countless nights
in years gone by to the savage chorus of similar roars. Scarcely a
day or night of his jungle life--and practically all his life had
been spent in the jungle--had he not heard the roaring of hungry
