Tarzan of the Apes was no sentimentalist. He knew nothing of the brotherhood of man. All things outside his own tribe were his deadly enemies, with the few exceptions of which Tantor, the elephant, was a marked example. And he realized all this without malice or hatred. To kill was the law of the wild world he knew. Few were his primitive pleasures, but the greatest of these was to hunt and kill, and so he accorded to others the right to cherish the same desires as he, even though he himself might be the object of their hunt. His strange life had left him neither morose nor bloodthirsty. That he joyed in killing, and that he killed with a joyous laugh upon his handsome lips betokened no innate cruelty. He killed for food most often, but, being a man, he sometimes killed for pleasure, a thing which no other animal does; for it has remained for man alone among all creatures to kill senselessly and wantonly for the mere pleasure of inflicting suffering and death. And when he killed for revenge, or in self-defense, he did that also without hysteria, for it was a very businesslike proceeding which admitted of no levity.

Had there been no other personal attribute to influence the final outcome, Tarzan of the Apes, the young Lord Greystoke, would have died as he had lived — an unknown savage beast in equatorial Africa. But there was that which had raised him far above his fellows of the jungle — that little spark which spells the whole vast difference between man and brute — Reason. This it was which saved him from death beneath the iron muscles and tearing fangs of Terkoz.

Tarzan was an interested spectator. His desire to kill burned fiercely in his wild breast, but his desire to learn was even greater. He would follow this savage creature for a while and know from whence he came. He could kill him at his leisure later, when the bow and deadly arrows were laid aside.

Tarzan let him up, and in a few minutes all were back at their vocations, as though naught had occurred to mar the tranquility of their primeval forest haunts. But deep in the minds of the apes was rooted the conviction that Tarzan was a mighty fighter and a strange creature. Strange because he had had it in his power to kill his enemy, but had allowed him to live — unharmed.

Tarzan of the Apes, young and savage beast of the jungle, wondered at the cruel brutality of his own kind. Sheeta, the leopard, alone of all the jungle folk, tortured his prey. The ethics of all the others meted a quick and merciful death to their victims.
Tarzan had learned from his books but scattered fragments of the ways of human beings.

As the body rolled to the ground Tarzan of the Apes placed his foot upon the neck of his lifelong enemy and, raising his eyes to the full moon, threw back his fierce young head and voiced the wild and terrible cry of his people.

Tarzan sat in a brown study for a long time after he finished reading the letter. It was filled with so many new and wonderful things that his brain was in a whirl as he attempted to digest them all. So they did not know that he was Tarzan of the Apes. He would tell them.
In his tree he had constructed a rude shelter of leaves and boughs, beneath which, protected from the rain, he had placed the few treasures brought from the cabin. Among these were some pencils.
He took one, and beneath Jane Porter's signature he wrote: I am Tarzan of the Apes

"I do not understand exactly what you mean by fear," said Tarzan. "Like lions, fear is a different thing in different men, but to me the only pleasure in the hunt is the knowledge that the hunted thing has power to harm me as much as I have to harm him. If I went out with a couple of rifles and a gun bearer, and twenty or thirty beaters, to hunt a lion, I should not feel that the lion had much chance, and so the pleasure of the hunt would be lessened in proportion to the increased safety which I felt."

"Then I am to take it that Monsieur Tarzan would prefer to go naked into the jungle, armed only with a jackknife, to kill the king of beasts," laughed the other good naturedly, but with the merest touch of sarcasm in his tone.

"And a piece of rope," added Tarzan.

He had seen fire, but only when Ara, the lightning, had destroyed some great tree. That any creature of the jungle could produce the red-and-yellow fangs which devoured wood and left nothing but fine dust surprised Tarzan greatly, and why the black warrior had ruined his delicious repast by plunging it into the blighting heat was quite beyond him. Possibly Ara was a friend with whom the Archer was sharing his food.
But, be that as it may, Tarzan would not ruin good meat in any such foolish manner, so he gobbled down a great quantity of the raw flesh, burying the balance of the carcass beside the trail where he could find it upon his return.

Tarzan held a peculiar position in the tribe. They seemed to consider him one of them and yet in some way different. The older males either ignored him entirely or else hated him so vindictively that but for his wondrous agility and speed and the fierce protection of the huge Kala he would have been dispatched at an early age.

Tarzan of the Apes lived on in his wild, jungle existence with little change for several years, only that he grew stronger and wiser, and learned from his books more and more of the strange worlds which lay somewhere outside his primeval forest.

Had Kala lived, Tarzan would have sacrificed all else to remain near her, but now that she was dead, and the playful friends of his childhood grown into fierce and surly brutes he felt that he much preferred the peace and solitude of his cabin to the irksome duties of leadership amongst a horde of wild beasts.

A personification, was Tarzan of the Apes, of the primitive man, the hunter, the warrior.
With the noble poise of his handsome head upon those broad shoulders, and the fire of life and intelligence in those fine, clear eyes, he might readily have typified some demigod of a wild and warlike bygone people of his ancient forest.
But of these things Tarzan did not think. He was worried because he had not clothing to indicate to all the jungle folks that he was a man and not an ape, and grave doubt often entered his mind as to whether he might not yet become an ape.

One by one the tribe swung down from their arboreal retreats and formed a circle about Tarzan and his vanquished foe. When they had all come Tarzan turned toward them. "I am Tarzan," he cried. "I am a great killer. Let all respect Tarzan of the Apes and Kala, his mother. There be none among you as mighty as Tarzan. Let his enemies beware."
