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 Ger-mans 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 realiza-tion 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 fore-warned 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 inter-vals 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 dilat-ing 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 dis-possessed. 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 com-bat, 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.
