"It has no eyes," said Tar-gash. "How could it see to fly?"
"It was not alive," replied Tarzan.
"I heard it growl," said the Sagoth; nor was he ever convinced that the thing was not some strange form of living creature.
They had covered but a short distance along the trail made by Gridley and Jana, after they had left the aeroplane, when they came upon the carcass of a huge pteranodon. Its head was crushed and battered and almost severed from its body and a splinter of smooth wood projected from its skull—a splinter that Tarzan recognized as a fragment of an aeroplane propeller —and instantly he knew the cause of Gridley's crash.
Half a mile further on the three discovered further evidence, some of it quite startling. An opened parachute lay stretched upon the ground where it had fallen and at short distances from it lay the bodies of four hyaenodons and two hairy men.
An examination of. the bodies revealed the fact that both of the men and two of the hyaenodons had died from bullet wounds. Everywhere upon the trampled turf appeared the imprints of the small sandals of Jason's companion. It was evident to the keen eyes of Tarzan that two other men, both natives, had taken part in the battle which had been waged here. That they were of the same tribe as the two that had fallen was evidenced by the imprints of their sandals, which were of identical make, while those of Tarzan's companion differed materially from all the others.
As be circled about, searching for further evidence, he saw that the two men who had escaped had run rapidly for some distance toward the mouth of a large canyon, and that, apparently following their retreat, Jason and his companion had set out in search of the plane. Later they had returned to the scene of the battle, and when they had departed they also had gone toward the mountains, but along a line considerably to the right of the trail made by the fleeing natives.
Thoar, too, was much interested in the various tracks that the participants in the battle by the parachute had left, but he said nothing until after Tarzan had completed his investigation.
"There were four men and either a woman or a youth here with my friend," said Tarzan.
"Four of them were law countrymen from Pheli," said Thoar, "and the other was a woman of Zoram."
"How do you know?" asked Tarzan, who was always anxious to add to his store of woodcraft.
"The low country sandals are never shaped to the foot as closely as are those of the mountain tribes," replied Thoar, "and the sales are much thinner, being made usually of the hides of the thag, which is tough enough for people who do not walk often upon anything but soft grasses or in soggy marshland. The sandals of the mountain tribes are soled with the thick hide of Maj, the cousin of Tandor. If you will look at the spoor you will see that they are not worn at all, while there are holes in the sandals of these dead men of Pheli."
"Are we near Zoram?" asked Tarzan.
"No," replied Thoar. "It lies across the highest range ahead of us."
"When we first met, Thoar, you told me that you were from Zoram."
"Yes, that is my country," replied Thoar.
"Then, perhaps, this woman is someone whom you know?"
"She is my sister," replied Thoar.
Tarzan of the Apes looked at him in surprise. "How do you know?" he demanded.
"I found an imprint where there was no turf, only soft earth, and there the spoor was so distinct that I could recognize the sandals as hers. So familiar with her work am I that I could recognize the stitching alone, where the sole is joined to the upper part of the sandal, and in addition there are the notches, which indicate the tribe. The people of Zoram have three notches in the underside of the sole at the toe of the left sandal."
"What was your sister doing so far from her own country and how is it that she is with my friend?"
"It is quite plain," replied Thoar. "These men of Pheli sought to capture her. One of them wanted her for his mate, but she eluded them and they pursued her across the Mountains of the Thipdars and down into this valley, where she was set upon by jaloks. The man from your country came and killed the jaloks and two of the Phelians and drove the other two away. It is evident that my sister could not escape him, and he captured her."
Tarzan of the Apes smiled. "The spoor does not indicate that she ever made any effort to escape him," he said.
Thoar scratched his head. "That is true," he replied, "and I cannot understand it, for the women of my tribe do not care to mate with the men of other tribes and I know that Jana, my sister, would rather die than mate outside the Mountains of the Thipdars. Many times has she said so and Jana is not given to idle talk."
"My friend would not take her by force," said Tarzan. "If she has gone with him, she has gone with him willingly. And I think that when we find them you will discover that he is simply accompanying her back to Zoram, for he is the sort of man who would not permit a woman to go alone and unprotected."
"We shall see," said Thoar, "but if he has taken Jana against her wishes, he must die."
As Tarzan, Tar-gash and Thoar followed the spoor of Jason and Jana a disheartened company of men rounded the end of the great Mountains of the Thipdars, fifty miles to the east of them, and entered the Gyor Cors, or great Plains of the Gyors.
The party consisted of ten black warriors and a white man, and, doubtless, never in the history of mankind had eleven men been more completely and hopelessly lost than these.
Muviro and his warriors, than whom no better trackers ever lived, were totally bewildered by their inability even to back-track successfully.
The stampeding of the maddened beasts, from which they had barely escaped with their lives and then only by what appeared nothing short of a miracle, had so obliterated all signs of the party's former spoor that though they were all confident that they had gone but a short distance from the clearing, into which the beasts had been herded by the tarags, they had never again been able to locate the clearing, and now they were wandering hopelessly and, in accordance with Von Horst's plans, keeping as much in the open as possible in the hope that the cruising O-220 might thus discover them, for Von Horst was positive that eventually his companions would undertake a search for them.
Aboard the O-220 the grave fear that had been entertained for the safety of the thirteen missing members of the ship's company had developed into a conviction of disaster when Gridley failed to return within the limit of the time that he might reasonably be able to keep the scout plane in the air.
Then it was that Zuppner had sent Dorf out with another searching party, but at the end of seventy hours they had returned to report absolute failure. They had followed the trail to a clearing where jackals fed upon rotting carrion, but beyond this there was no sign of spoor to suggest in what direction their fellows had wandered.
Going and coming they had been beset by savage beasts and so ruthless and determined had been the attacks of the giant tarags that Dorf reported to Zuppner that he was confident that all of the missing members of the party must by this time have been destroyed by these great cats.
"Until we have proof of that, we must not give up hope," replied Zuppner, "nor may we relinquish our efforts to find them, whether dead or alive, and that we cannot do by remaining here."
There was nothing now to delay the start. While the motors were warming up, the anchor was drawn in and the air expelled from the lower vacuum tanks. As the giant ship rose from the ground Robert Jones jotted down a brief note in a greasy memorandum book: "We sailed from here at noon."

When Skruk and his companion had left the field to the victorious Jason, the latter had returned his six-gun to its holster and faced the girl. "Well," he inquired, "what now?"
