always until he had given it as a token of his highest devotion to Jane Clayton before their marriage was missing. She always had worn it since, but it had not been upon her body when he found her slain in her boudoir, so that now his quest for vengeance included also a quest for the stolen trinket.

Toward midnight Tarzan commenced to feel the physical strain of his long hours of travel and to realize that even muscles such as his had their limitations. His pursuit of the murderers had not been characterized by excessive speed; but rather more in keeping with his mental attitude, which was marked by a dogged determination to require from the Germans more than an eye for an eye and more than a tooth for a tooth, the element of time entering but slightly into his calculations.

Inwardly as well as outwardly Tarzan had reverted to beast and in the lives of beasts, time, as a measurable aspect of duration, has no meaning. The beast is actively interested only in NOW, and as it is always NOW and always shall be, there is an eternity of time for the accomplishment of objects. The ape-man, naturally, had a slightly more comprehensive realization of the limitations of time; but, like the beasts, he moved with majestic deliberation when no emergency prompted him to swift action.

Having dedicated his life to vengeance, vengeance became his natural state and, therefore, no emergency, so he took his time in pursuit. That he had not rested earlier was due to the fact that he had felt no fatigue, his mind being occupied by thoughts of sorrow and revenge; but now he realized that he was tired, and so he sought a jungle giant that had harbored him upon more than a single other jungle night.

Dark clouds moving swiftly across the heavens now and again eclipsed the bright face of Goro, the moon, and forewarned the ape-man of impending storm. In the depth of the jungle the cloud shadows produced a thick blackness that might almost be felt—a blackness that to you and me might have proven terrifying with its accompaniment of rustling leaves and cracking twigs, and its even more suggestive intervals of utter silence in which the crudest of imaginations might have conjured crouching beasts of prey tensed for the fatal charge; but through it Tarzan passed unconcerned, yet always alert. Now he swung lightly to the lower terraces of the overarching trees when some subtle sense warned him that Numa lay upon a kill directly in his path, or again he sprang lightly to one side as Buto, the rhinoceros, lumbered toward him along the narrow, deep-worn trail, for the ape-man, ready to fight upon necessity's slightest pretext, avoided unnecessary quarrels.

When he swung himself at last into the tree he sought, the moon was obscured by a heavy cloud, and the tree tops were waving wildly in a steadily increasing wind whose soughing drowned the lesser noises of the jungle. Upward went Tarzan toward a sturdy crotch across which he long since had laid and secured a little platform of branches. It was very dark now, darker even than it had been before, for almost the entire sky was overcast by thick, black clouds.

Presently the man-beast paused, his sensitive nostrils dilating as he sniffed the air about him. Then, with the swiftness and agility of a cat, he leaped far outward upon a swaying branch, sprang upward through the darkness, caught another, swung himself upon it and then to one still higher. What could have so suddenly transformed his matter-of-fact ascent of the giant bole to the swift and wary action of his detour among the branches? You or I could have seen nothing—not even the little platform that an instant before had been just above him and which now was immediately below—but as he swung above it we should have heard an ominous growl; and then as the moon was momentarily uncovered, we should have seen both the platform, dimly, and a dark mass that lay stretched upon it—a dark mass that presently, as our eyes became accustomed to the lesser darkness, would take the form of Sheeta, the panther.

In answer to the cat's growl, a low and equally ferocious growl rumbled upward from the ape-man's deep chest—a growl of warning that told the panther he was trespassing upon the other's lair; but Sheeta was in no mood to be dispossessed. With upturned, snarling face he glared at the brown-skinned Tarmangani above him. Very slowly the ape-man moved inward along the branch until he was directly above the panther. In the man's hand was the hunting knife of his long-dead father—the weapon that had first given him his real ascendancy over the beasts of the jungle; but he hoped not to be forced to use it, knowing as he did that more jungle battles were settled by hideous growling than by actual combat, the law of bluff holding quite as good in the jungle as elsewhere—only in matters of love and food did the great beasts ordinarily close with fangs and talons.

Tarzan braced himself against the bole of the tree and leaned closer toward Sheeta.

"Stealer of balus!" he cried. The panther rose to a sitting position, his bared fangs but a few feet from the ape-man's taunting face. Tarzan growled hideously and struck at the cat's face with his knife. "I am Tarzan of the Apes," he roared. "This is Tarzan's lair. Go, or I will kill you."

Though he spoke in the language of the great apes of the jungle, it is doubtful that Sheeta understood the words, though he knew well enough that the hairless ape wished to frighten him from his well-chosen station past which edible creatures might be expected to wander sometime during the watches of the night.

Like lightning the cat reared and struck a vicious blow at his tormentor with great, bared talons that might well have torn away the ape-man's face had the blow landed; but it did not land—Tarzan was even quicker than Sheeta. As the panther came to all fours again upon the little platform, Tarzan un-slung his heavy spear and prodded at the snarling face, and as Sheeta warded off the blows, the two continued their horrid duet of blood-curdling roars and growls.

Goaded to frenzy the cat presently determined to come up after this disturber of his peace; but when he essayed to leap to the branch that held Tarzan he found the sharp spear point always in his face, and each time as he dropped back he was prodded viciously in some tender part; but at length, rage having conquered his better judgment, he leaped up the rough bole to the very branch upon which Tarzan stood. Now the two faced each other upon even footing and Sheeta saw a quick revenge and a supper all in one. The hairless ape-thing with the tiny fangs and the puny talons would be helpless before him.

The heavy limb bent beneath the weight of the two beasts as Sheeta crept cautiously out upon it and Tarzan backed slowly away, growling. The wind had risen to the proportions of a gale so that even the greatest giants of the forest swayed, groaning, to its force and the branch upon which the two faced each other rose and fell like the deck of a storm-tossed ship. Goro was now entirely obscured, but vivid flashes of lightning lit up the jungle at brief intervals, revealing the grim tableau of primitive passion upon the swaying limb.

Tarzan backed away, drawing Sheeta farther from the stem of the tree and out upon the tapering branch, where his footing became ever more precarious. The cat, infuriated by the pain of spear wounds, was overstepping the bounds of caution. Already he had reached a point where he could do little more than maintain a secure footing, and it was this moment that Tarzan chose to charge. With a roar that mingled with the booming thunder from above he leaped toward the panther, who could only claw futilely with one huge paw while he clung to the branch with the other; but the ape-man did not come within that parabola of destruction. Instead he leaped above menacing claws and snapping fangs, turning in mid-air and alighting upon Sheeta's back, and at the instant of impact his knife struck deep into the tawny side. Then Sheeta, impelled by pain and hate and rage and the
