you think the lions got Oldwick?" asked the colonel.
"I doubt it," replied Lieutenant Thompson, "from the fact that there was no indication that the lion had fed anywhere about the plane. I arose after I found it was impossible to get down around the plane and reconnoitered up and down the gorge. Several miles to the south I found a small, wooded valley in the center of which—please don't think me crazy, sir—is a regular city—streets, buildings, a central plaza with a lagoon, good-sized buildings with domes and minarets and all that sort of stuff."
The elder officer looked at the younger compassionately. "You're all wrought up, Thompson," he said. "Go and take a good sleep. You have been on this job now for a long while and it must have gotten on your nerves."
The young man shook his head a bit irritably. "Pardon me, sir," he said, "but I am telling you the truth. I am not mistaken. I circled over the place several times. It may be that Oldwick has found his way there—or has been captured by these people."
"Were there people in the city?" asked the colonel.
"Yes, I saw them in the streets."
"Do you think cavalry could reach the valley?" asked the colonel.
"No," replied Thompson, "the country is all cut up with these deep gorges. Even infantry would have a devil of a time of it, and there is absolutely no water that I could discover for at least a two days' march."
It was at this juncture that a big Vauxhall drew up in front of the headquarters of the Second Rhodesians and a moment later General Smuts alighted and entered. Colonel Capell arose from his chair and saluted his superior, and the young lieutenant saluted and stood at attention.
"I was passing," said the general, "and I thought I would stop for a chat. By the way, how is the search for Lieutenant Smith-Oldwick progressing? I see Thompson here and I believe he was one of those detailed to the search."
"Yes," said Capell, "he was. He is the last to come in. He found the lieutenant's ship," and then he repeated what Lieutenant Thompson had reported to him. The general sat down at the table with Colonel Capell, and together the two officers, with the assistance of the flier, marked the approximate location of the city which Thompson had reported he'd discovered.
"It's a mighty rough country," remarked Smuts, "but we can't leave a stone unturned until we have exhausted every resource to find that boy. We will send out a small force; a small one will be more likely to succeed than a large one. About one company, Colonel, or say two, with sufficient motor lorries for transport of rations and water. Put a good man in command and let him establish a base as far to the west as the motors can travel. You can leave one company there and send the other forward. I am inclined to believe you can establish your base within a day's march of the city and if such is the case the force you send ahead should have no trouble on the score of lack of water as there certainly must be water in the valley where the city lies. Detail a couple of planes for reconnaissance and messenger service so that the base can keep in touch at all times with the advance party. When can your force move out?"
"We can load the lorries tonight," replied Capell, "and march about one o'clock tomorrow morning."
"Good," said the general, "keep me advised," and returning the others' salutes he departed.
As Tarzan leaped for the vines he realized that the lion was close upon him and that his life depended upon the strength of the creepers clinging to the city walls; but to his intense relief he found the stems as large around as a man's arm, and the tendrils which had fastened themselves to the wall so firmly fixed, that his weight upon the stem appeared to have no appreciable effect upon them.
He heard Numa's baffled roar as the lion slipped downward clawing futilely at the leafy creepers, and then with the agility of the apes who had reared him, Tarzan bounded nimbly aloft to the summit of the wall.
A few feet below him was the flat roof of the adjoining building and as he dropped to it his back was toward the niche from which an embrasure looked out upon the gardens and the forest beyond, so that he did not see the figure crouching there in the dark shadow. But if he did not see he was not long in ignorance of the fact that he was not alone, for scarcely had his feet touched the roof when a heavy body leaped upon him from behind and brawny arms encircled him about the waist.
Taken at a disadvantage and lifted from his feet, the ape-man was, for the time being, helpless. Whatever the creature was that had seized him, it apparently had a well-defined purpose in mind, for it walked directly toward the edge of the roof so that it was soon apparent to Tarzan that he was to be hurled to the pavement below—a most efficacious manner of disposing of an intruder. That he would be either maimed or killed the ape-man was confident; but he had no intention of permitting his assailant to carry out the plan.
Tarzan's arms and legs were free but he was in such a disadvantageous position that he could not use them to any good effect. His only hope lay in throwing the creature off its balance, and to this end Tarzan straightened his body and leaned as far back against his captor as he could, and then suddenly lunged forward. The result was as satisfactory as he could possibly have hoped. The great weight of the ape-man thrown suddenly out from an erect position caused the other also to lunge violently forward with the result that to save himself he involuntarily released his grasp. Catlike in his movements, the ape-man had no sooner touched the roof than he was upon his feet again, facing his adversary, a man almost as large as himself and armed with a saber which he now whipped from its scabbard. Tarzan, however, had no mind to allow the use of this formidable weapon and so he dove for the other's legs beneath the vicious cut that was directed at him from the side, and as a football player tackles an opposing runner, Tarzan tackled his antagonist, carrying him backward several yards and throwing him heavily to the roof upon his back.
No sooner had the man touched the roof than the ape-man was upon his chest, one brawny hand sought and found the sword wrist and the other the throat of the yellow-tunicked guardsman. Until then the fellow had fought in silence but just as Tarzan's fingers touched his throat he emitted a single piercing shriek that the brown fingers cut off almost instantly. The fellow struggled to escape the clutch of the naked creature upon his breast but equally as well might he have fought to escape the talons of Numa, the lion.
Gradually his struggles lessened, his pin-point eyes popped from their sockets, rolling horribly upward, while from his foam-flecked lips his swollen tongue protruded. As his struggles ceased Tarzan arose, and placing a foot upon the carcass of his kill, was upon the point of screaming forth his victory cry when the thought that the work before him required the utmost caution sealed his lips.
Walking to the edge of the roof he looked down into the narrow, winding street below. At intervals, apparently at each street intersection, an oil flare sputtered dimly from brackets set in the walls a trifle higher than a man's head. For the most part the winding alleys were in dense shadow and even in the immediate vicinity of the flares the illumination was far from brilliant. In the restricted area of his vision he could see that there were still a few of the strange inhabitants moving about the narrow thoroughfares.
To prosecute his search for the young officer and the girl he must be able to move about the city as freely as possible, but to pass beneath one of the corner flares, naked as he was except for a loin cloth, and in every other respect markedly different from the inhabitants of the city, would be but to court almost immediate discovery. As these thoughts flashed through his mind and he cast about for some feasible plan of action, his eyes fell upon the corpse upon the roof near him, and immediately there occurred to him the possibility of disguising himself in the raiment of his conquered adversary.
It required but a few moments for the ape-man to clothe himself in the tights, sandals, and parrot emblazoned yellow tunic of the dead soldier. Around his waist he buckled the
