And so, when the GRYF halted, Tarzan slid to the ground, struck the creature a careless blow across the flank as though in dismissal and walked indifferently away. From the throat of the beast came a low rumbling sound and without even a glance at Tarzan it turned and entered the river where it stood drinking for a long time.
Convinced that the GRYF no longer constituted a menace to him the ape-man, spurred on himself by the gnawing of hunger, unslung his bow and selecting a handful of arrows set forth cautiously in search of food, evidence of the near presence of which was being borne up to him by a breeze from down river.
Ten minutes later he had made his kill, again one of the Pal-ul-don specimens of antelope, all species of which Tarzan had known since childhood as Bara, the deer, since in the little primer that had been the basis of his education the picture of a deer had been the nearest approach to the likeness of the antelope, from the giant eland to the smaller bushbuck of the hunting grounds of his youth.
Cutting off a haunch he cached it in a nearby tree, and throwing the balance of the carcass across his shoulder trotted back toward the spot at which he had left the GRYF. The great beast was just emerging from the river when Tarzan, seeing it, issued the weird cry of the Tor-o-don. The creature looked in the direction of the sound voicing at the same time the low rumble with which it answered the call of its master. Twice Tarzan repeated his cry before the beast moved slowly toward him, and when it had come within a few paces he tossed the carcass of the deer to it, upon which it fell with greedy jaws.
"If anything will keep it within call," mused the ape-man as he returned to the tree in which he had cached his own portion of his kill, "it is the knowledge that I will feed it." But as he finished his repast and settled himself comfortably for the night high among the swaying branches of his eyrie he had little confidence that he would ride into A-lur the following day upon his prehistoric steed.
When Tarzan awoke early the following morning he dropped lightly to the ground and made his way to the stream. Removing his weapons and loin cloth he entered the cold waters of the little pool, and after his refreshing bath returned to the tree to breakfast upon another portion of Bara, the deer, adding to his repast some fruits and berries which grew in abundance nearby.
His meal over he sought the ground again and raising his voice in the weird cry that he had learned, he called aloud on the chance of attracting the GRYF, but though he waited for some time and continued calling there was no response, and he was finally forced to the conclusion that he had seen the last of his great mount of the preceding day.
And so he set his face toward A-lur, pinning his faith upon his knowledge of the Ho-don tongue, his great strength and his native wit.
Refreshed by food and rest, the journey toward A-lur, made in the cool of the morning along the bank of the joyous river, he found delightful in the extreme. Differentiating him from his fellows of the savage jungle were many characteristics other than those physical and mental. Not the least of these were in a measure spiritual, and one that had doubtless been as strong as another in influencing Tarzan's love of the jungle had been his appreciation of the beauties of nature. The apes cared more for a grubworm in a rotten log than for all the majestic grandeur of the forest giants waving above them. The only beauties that Numa acknowledged were those of his own person as he paraded them before the admiring eyes of his mate, but in all the manifestations of the creative power of nature of which Tarzan was cognizant he appreciated the beauties.
As Tarzan neared the city his interest became centered upon the architecture of the outlying buildings which were hewn from the chalklike limestone of what had once been a group of low hills, similar to the many grass-covered hillocks that dotted the valley in every direction. Ta-den's explanation of the Ho-don methods of house construction accounted for the ofttimes remarkable shapes and proportions of the buildings which, during the ages that must have been required for their construction, had been hewn from the limestone hills, the exteriors chiseled to such architectural forms as appealed to the eyes of the builders while at the same time following roughly the original outlines of the hills in an evident desire to economize both labor and space. The excavation of the apartments within had been similarly governed by necessity.
