In his left hand was his bow and between the fingers four extra arrows.

As Ara the lightning, so is Tarzan for swiftness. The instant that he had discovered and recognized the menace creeping upon him from behind and known that he had been seen by the horsemen, he had leaped to his feet, and in the same instant strung his bow. Now, perhaps even before the leading Shiftas realized the danger that confronted them, the bow was bent, the shaft sped.

Short but powerful was the bow of the ape-man; short, that it might be easily carried through the forest and the jungle; powerful, that it might send its shafts through the toughest hide to a vital organ of its prey. Such a bow was this that no ordinary man might bend it.

Straight through the heart of the leading Shifta drove the first arrow, and as the fellow threw his arms above his head and lunged from his saddle four more arrows sped with lightning-like rapidity from the bow of the ape-man, and every arrow found a target. Another Shifta dropped to ride no more, and three were wounded.

Only seconds had elapsed since Tarzan had discovered his danger, and already the four remaining horsemen were upon him. The three who were wounded were more interested in the feathered shafts protruding from their bodies than in the quarry they had expected so easily to overcome, but the fourth was whole, and he thundered down upon the ape-man with his spear set for the great chest.

There could be no retreat for Tarzan; there could be no side-stepping to avoid the thrust, for a step to either side would have carried him in front of one of the other horsemen. He had but a single slender hope for survival, and that hope, forlorn though it appeared, he seized upon with the celerity, strength, and agility that make Tarzan Tarzan. Slipping his bowstring about his neck after his final shot, he struck up the point of the menacing weapon of his antagonist, and grasping the man's arm swung himself to the horse's back behind the rider.

As steel-thewed fingers closed upon the Shifta's throat he voiced a single piercing scream; then a knife drove home beneath his left shoulder blade, and Tarzan hurled the body from the saddle. The terrified horse, running free with flying reins, tore through the bushes and the reeds into the river, while the remaining shqtas, disabled by their wounds, were glad to abandon the chase upon the bank, though one of them, retaining more vitality than his companions, did raise his matchlock and send a parting shot after the escaping quarry.

The river was a narrow, sluggish stream but deep in the channel, and as the horse plunged into it, Tarzan saw a commotion in the water a few yards downstream and then the outline of a long sinuous body moving swiftly toward them. It was Gimla the crocodile. The horse saw it too and, becoming frantic, turned upstream in an effort to escape. Tarzan climbed over the high cantle of the Abyssinian saddle and unslung his spear in the rather futile hope of holding the reptile at bay until his mount could reach the safety of the opposite bank toward which he was now attempting to guide him.

Gimla is as swift as he is voracious. He was already at the horse's rump, with opened jaws, when the Shifta at the river's edge fired wildly at the ape-man. It was well for Tarzan that the wounded man had fired hurriedly, for simultaneously with the report of the firearm, the crocodile dove, and the frenzied lashing of the water about him evidenced the fact that he had been mortally wounded.

A moment later the horse that Tarzan rode reached the opposite bank and clambered to the safety of dry land. Now he was under control again, and the ape-man wheeled him about and sent a parting arrow across the river toward the angry, cursing bandits upon the opposite side, an arrow that found its mark in the thigh of the already wounded man who had unwittingly rescued Tarzan from a serious situation with the shot that had been intended to kill him.

To the accompaniment of a few wild and scattered shots, Tarzan of the Apes galloped toward a nearby forest into which he disappeared from the sight of the angry Shiftas.

CHAPTER TWO THE WHITE PRISONER

Far to the south a lion rose from his kill and walked majestically to the edge of a nearby river. He cast not so much as a single glance at the circle of hyenas and jackals that had ringed him and his kill waiting for him to depart and which had broken and retreated as he rose. Nor, when the hyenas rushed in to tear at what he had left, did he appear even to see them.

There were the pride and bearing of royalty in the mien of this mighty beast, and to add to his impressiveness were his great size, his yellow, almost golden, coat, and his great black mane. When he had drunk his fill, he lifted his massive head and voiced a roar, as is the habit of lions when they have fed and drunk, and the earth shook to his thunderous voice, and a hush fell upon the jungle.

Now he should have sought his lair and slept, to go forth again at night and kill, but he did not do so. He did not do at all what might have been expected of a lion under similar circumstances. He raised his head and sniffed the air, and then he put his nose to the ground and moved to and fro like a hunting dog searching for a game scent. Finally he halted and voiced a low roar; then, with head raised, he moved off along a trail that led toward the north. The hvenas were glad to see him go; so were the jackals, who wished that the haenas would go also. Ska the vulture, circling above, wished that they would all leave.

At about the same time, many marches to the north, three angry, wounded Shiftas viewed their dead comrades and cursed the fate that had led them upon the trail of the strange white giant. Then they stripped the clothing and weapons from their dead fellows and rode away, loudly vowing vengeance should they ever again come upon the author of their discomfiture and secretly hoping that they never would. They hoped that they were done with him, but they were not.

Shortly after he had entered the forest, Tarzan swung to an overhanging branch beneath which his mount was passing and let the animal go its way. The ape-man was angry; the Shiftas had frightened away his dinner. That they had sought to kill him annoyed him far less than the fact that they had spoiled his hunting. Now he must commence his search for meat all over again, but when he had filled his belly he would look into this matter of Shiftas. Of this he was certain.

Tarzan hunted again until he had found flesh, nor was it long before he had made his kill and eaten it.

Satisfied, he lay up for a while in the crotch of a tree, but not for long. His active mind was considering the matter of the Shiftas.
