The lioness was intently watching Tarzan, evidently expecting him to return to shore, but this the boy had no intention of doing.
Instead he raised his voice in the call of distress common to his tribe, adding to it the warning which would prevent would-be rescuers from running into the clutches of Sabor.
Almost immediately there came an answer from the distance, and presently forty or fifty great apes swung rapidly and majestically through the trees toward the scene of tragedy.
In the lead was Kala, for she had recognized the tones of her best beloved, and with her was the mother of the little ape who lay dead beneath cruel Sabor.
Though more powerful and better equipped for fighting than the apes, the lioness had no desire to meet these enraged adults, and with a snarl of hatred she sprang quickly into the brush and disappeared.
Tarzan now swam to shore and clambered quickly upon dry land. The feeling of freshness and exhilaration which the cool waters had imparted to him, filled his little being with grateful surprise, and ever after he lost no opportunity to take a daily plunge in lake or stream or ocean when it was possible to do so.
For a long time Kala could not accustom herself to the sight; for though her people could swim when forced to it, they did not like to enter water, and never did so voluntarily.
The adventure with the lioness gave Tarzan food for pleasurable memories, for it was such affairs which broke the monotony of his daily life—otherwise but a dull round of searching for food, eating, and sleeping.
The tribe to which he belonged roamed a tract extending, roughly, twenty-five miles along the seacoast and some fifty miles inland. This they traversed almost continually, occasionally remaining for months in one locality; but as they moved through the trees with great speed they often covered the territory in a very few days.
Much depended upon food supply, climatic conditions, and the prevalence of animals of the more dangerous species; though Kerchak often led them on long marches for no other reason than that he had tired of remaining in the same place.
At night they slept where darkness overtook them, lying upon the ground, and sometimes covering their heads, and more seldom their bodies, with the great leaves of the elephant's ear. Two or three might lie cuddled in each other's arms for additional warmth if the night were chill, and thus Tarzan had slept in Kala's arms nightly for all these years.
That the huge, fierce brute loved this child of another race is beyond question, and he, too, gave to the great, hairy beast all the affection that would have belonged to his fair young mother had she lived.
When he was disobedient she cuffed him, it is true, but she was never cruel to him, and was more often caressing him than chastising him.
Tublat, her mate, always hated Tarzan, and on several occasions had come near ending his youthful career.
Tarzan on his part never lost an opportunity to show that he fully reciprocated his foster father's sentiments, and whenever he could safely annoy him or make faces at him or hurl insults upon him from the safety of his mother's arms, or the slender branches of the higher trees, he did so.
His superior intelligence and cunning permitted him to invent a thousand diabolical tricks to add to the burdens of Tublat's life.
Early in his boyhood he had learned to form ropes by twisting and tying long grasses together, and with these he was forever tripping Tublat or attempting to hang him from some overhanging branch.
By constant playing and experimenting with these he learned to tie rude knots, and make sliding nooses; and with these he and the younger apes amused themselves. What Tarzan did they tried to do also, but he alone originated and became proficient.
One day while playing thus Tarzan had thrown his rope at one of his fleeing companions, retaining the other end in his grasp. By accident the noose fell squarely about the running ape's neck, bringing him to a sudden and surprising halt.
Ah, here was a new game, a fine game, thought Tarzan, and immediately he attempted to repeat the trick. And thus, by painstaking and continued practice, he learned the art of roping.
Now, indeed, was the life of Tublat a living nightmare. In sleep, upon the march, night or day, he never knew when that quiet noose would slip about his neck and nearly choke the life out of him.
Kala punished, Tublat swore dire vengeance, and old Kerchak took notice and warned and threatened; but all to no avail.
Tarzan defied them all, and the thin, strong noose continued to settle about Tublat's neck whenever he least expected it.
The other apes derived unlimited amusement from Tublat's discomfiture, for Broken Nose was a disagreeable old fellow, whom no one liked, anyway.
In Tarzan's clever little mind many thoughts revolved, and back of these was his divine power of reason.
If he could catch his fellow apes with his long arm of many grasses, why not Sabor, the lioness?
It was the germ of a thought, which, however, was destined to mull around in his conscious and subconscious mind until it resulted in magnificent achievement.
But that came in later years.

Jungle Battles
The wanderings of the tribe brought them often near the closed and silent cabin by the little land-locked harbor. To Tarzan this was always a source of never-ending mystery and pleasure.
He would peek into the curtained windows, or, climbing upon the roof, peer down the black depths of the chimney in vain endeavor to solve the unknown wonders that lay within those strong walls.
His child-like imagination pictured wonderful creatures within, and the very impossibility of forcing entrance added a thousandfold to his desire to do so.
He could clamber about the roof and windows for hours attempting to discover means of ingress, but to the door he paid little attention, for this was apparently as solid as the walls.
It was in the next visit to the vicinity, following the adventure with old Sabor, that, as he approached the cabin, Tarzan noticed that from a distance the door appeared to be an independent part of the wall in which it was set, and for the first time it occurred to him that this might prove the means of entrance which had so long eluded him.
He was alone, as was often the case when he visited the cabin, for the apes had no love for it; the story of the thunder-stick having lost nothing in the telling during these ten years had quite surrounded the white man's deserted abode with an atmosphere of weirdness and terror for the simians.
The story of his own connection with the cabin had never been told him. The language of the apes had so few words that they could talk but little of what they had seen in the cabin, having no words to accurately describe either the strange people or their belongings, and so, long before Tarzan was old enough to understand, the subject had been forgotten by the tribe.
Only in a dim, vague way had Kala explained to him that his father had been a strange white ape, but he did not know that Kala was not his own mother.
On this day, then, he went directly to the door and spent hours examining it and fussing with the hinges, the knob and the latch. Finally he stumbled upon the right combination, and the door swung creakingly open before his astonished eyes.
For some minutes he did not dare venture within, but finally, as his eyes became accustomed to the dim light of the interior he slowly and cautiously entered.
In the middle of the floor lay a skeleton, every vestige of flesh gone from the bones to which still clung the mildewed and moldered remnants of what had once been clothing. Upon
