A little mountain stream tumbles down from Kor-ul-gryf to be joined in the foothills with that which empties the waters of Kor-ul-lul into the valley, forming a small river which runs southwest, eventually entering the valley’s largest lake at the City of A-lur, through the center of which the stream passes. An ancient trail, well marked by countless generations of naked feet of man and beast, leads down toward A-lur beside the river, and along this Tarzan guided the gryf. Once clear of the forest which ran below the mouth of the gorge, Tarzan caught occasional glimpses of the city gleaming in the distance far below him.
The country through which he passed was resplendent with the riotous beauties of tropical verdure. Thick, lush grasses grew waist high upon either side of the trail and the way was broken now and again by patches of open park-like forest, or perhaps a little patch of dense jungle where the trees overarched the way and trailing creepers depended in graceful loops from branch to branch.
At times the ape-man had difficulty in commanding obedience upon the part of his unruly beast, but always in the end its fear of the relatively puny goad urged it on to obedience. Late in the afternoon as they approached the confluence of the stream they were skirting and another which appeared to come from the direction of Kor-ul-ja the ape-man, emerging from one of the jungle patches, discovered a considerable party of Ho-don upon the opposite bank. Simultaneously they saw him and the mighty creature he bestrode. For a moment they stood in wide-eyed amazement and then, in answer to the command of their leader, they turned and bolted for the shelter of the nearby wood.
The ape-man had but a brief glimpse of them but it was sufficient indication that there were Waz-don with them, doubtless prisoners taken in one of the raids upon the Waz-don villages of which Ta-den and Om-at had told him.
At the sound of their voices the gryf had bellowed terrifically and started in pursuit even though a river intervened, but by dint of much prodding and beating, Tarzan had succeeded in heading the animal back into the path though thereafter for a long time it was sullen and more intractable than ever.
As the sun dropped nearer the summit of the western hills Tarzan became aware that his plan to enter A-lur upon the back of a gryf was likely doomed to failure, since the stubbornness of the great beast was increasing momentarily, doubtless due to the fact that its huge belly was crying out for food. The ape-man wondered if the Tor-o-dons had any means of picketing their beasts for the night, but as he did not know and as no plan suggested itself, he determined that he should have to trust to the chance of finding it again in the morning.
There now arose in his mind a question as to what would be their relationship when Tarzan had dismounted. Would it again revert to that of hunter and quarry or would fear of the goad continue to hold its supremacy over the natural instinct of the hunting flesh-eater? Tarzan wondered but as he could not remain upon the gryf forever, and as he preferred dismounting and putting the matter to a final test while it was still light, he decided to act at once.
How to stop the creature he did not know, as up to this time his sole desire had been to urge it forward. By experimenting with his staff, however, he found that he could bring it to a halt by reaching forward and striking the thing upon its beaklike snout. Close by grew a number of leafy trees, in any one of which the ape-man could have found sanctuary, but it had occurred to him that should he immediately take to the trees it might suggest to the mind of the gryf that the creature that had been commanding him all day feared him, with the result that Tarzan would once again be held a prisoner by the triceratops.
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
