All day long they had waited expectantly for signs of rescue, though realizing that they were awaiting the impossible. Men on foot could not have overtaken the horsemen, and no motor could traverse the trail they had followed without long delays for clearing trail in many places.
"I can't stand much more," said Naomi. "I'm about through."
Rhonda reined closer to her. "If you feel like falling, take hold of me," she said. "It can't last much longer today. They'll be making camp soon. It sure has been a tough ride—not much like following Ernie Vogt up Coldwater Canyon ; and I used to come home from one of those rides and think I'd done something. Whew! They must have paved this saddle with bricks."
"I don't see how you can stay so cheerful."
"Cheerful! I'm about as cheerful as a Baby Star whose option hasn't been renewed."
"Do you think they're going to kill us, Rhonda?"
"They wouldn't have bothered to bring us all this way to kill us. They're probably after a ransom."
"I hope you're right. Tom'll pay 'em anything to get us back. But suppose they're going to sell us! I've heard that they sell white girls to black sultans in Africa."
"The black sultan that gets me is goin' to be out of luck."
The sun was low in the west when the Arabs made camp that night. Sheykh Ab el-Ghrennem had no doubt but that angry and determined men were pursuing him, but he felt quite certain that now they could not overtake him.
His first thought had been to put distance between himself and the Nasara he had betrayed—now he could look into the matter of the map of which Atewy had told him, possession of which had been the principal incentive of his knavery.
Supper over, he squatted where the light of the fire fell upon the precious document; and Atewy leaning over his shoulder scanned it with him.
"I can make nothing of it," growled the sheykh. "Fetch the bint from whom you took it."
"I shall have to fetch them both," replied Atewy, "since I cannot tell them apart."
"Fetch them both then," commanded el-Ghrennem; and while he waited he puffed meditatively upon his nargily, thinking of a valley filled with diamonds and of the many riding camels and mares that they would buy; so that he was in a mellow humor when Atewy returned with the prisoners.
Rhonda walked with her chin up and the glint of battle in her eye, but Naomi revealed her fear in her white face and trembling limbs.
Sheykh Ab el-Ghrennem looked at her and smiled. "Ma aleyk," he said in what were meant to be reassuring tones.
"He says," interpreted Atewy, "that thou hast nothing to fear—that there shall no evil befall thee."
"You tell him," replied Rhonda, "that it will be just too bad for him if any evil does befall us and that if he wants to save his skin he had better return us to our people pronto."
"The Bedauwy are not afraid of your people," replied Atewy, "but if you do what the sheykh asks no harm will come to you."
"What does he want?" demanded Rhonda.
"He wishes you to help us find the valley of diamonds," replied Atewy.
"What valley of diamonds?"
"It is on this map which we cannot read because we cannot read the language of el-Engleys." He pointed at the map the sheykh was holding.
Rhonda glanced at the paper and broke into laughter. "You don't mean to tell me that you dumb bunnies kidnapped us because you believe that there is a valley of diamonds! Why, that's just a prop map."
"Dumb bunnies! Prop! I do not understand."
"I am trying to tell you that that map doesn't mean a thing. It was just for use in the picture we are making. You might as well return us to our people, for there isn't any valley of diamonds."
Atewy and the sheykh jabbered excitedly to one another for a few moments, and then the former turned again to the girl. "You cannot make fools of the Bedauwy," he said. "We are smarter than you. We knew that you would say that there is no valley of diamonds, because you want to save it all for your father. If you know what is well for you, you will read this map for us and help us find the valley. Otherwise—" he scowled horridly and drew a forefinger across his throat.
Naomi shuddered; but Rhonda was not impressed—she knew that while they had ransom or sale value the Arabs would not destroy them except as a last resort for self-protection.
"You are not going to kill us, Atewy," she said, "even if I do not read the map to you; but there is no reason why I should not read it. I am perfectly willing to; only don't blame us if there is no valley of diamonds."
"Come here and sit beside Ab el-Ghrennem and read the map to us," ordered Atewy.
Rhonda kneeled beside the sheykh and looked over his shoulder at the yellowed, timeworn map. With a slender finger she pointed at the top of the map. "This is north," she said, "and up here—this is the valley of diamonds. You see this little irregular thing directly west of the valley and close to it? It has an arrow pointing to it and a caption that says, 'Monolithic column: Red granite outcropping near only opening into valley.' And right north of it this arrow points to 'Entrance to valley.'
"Now here, at the south end of the valley, is the word 'Falls' and below the falls a river that runs south and then southwest."
"Ask her what this is," the sheykh instructed Atewy, pointing to characters at the eastern edge of the map southeast of the falls.
"That says 'Cannibal village,'" explained the girl. "And all across the map down there it says, 'Forest!' See this river that rises at the southeast edge of the valley, flows east, southeast, and then west in a big loop before it enters the 'Big river' here. Inside this loop it says, 'Open country,' and near the west end of the loop is a 'Barren, cone-shaped hill —volcanic.' Then here is another river that rises in the southeast part of the map and flows northwest, emptying into the second river just before the latter joins the big river."
Sheykh Ab el-Ghrennem ran his fingers through his beard as he sat in thoughtful contemplation of the map. At last he placed a finger on the falls.
"Shuf, Atewy!" he exclaimed. "This should be the Omwamwi Falls, and over here the village of the Bansuto. We are here." He pointed at a spot near the junction of the second and third rivers. "Tomorrow we should cross this other river and come into open country. There we shall find a barren hill."
"Billah!" exclaimed Atewy. "If we do we shall soon be in the valley of diamonds, for the rest of the way is plain."
"What did the sheik say?" asked Rhonda.
Atewy told her, adding, "We shall all be very rich; then I shall buy you from the sheykh and take you back to my ashirat."
"You and who else?" scoffed Rhonda.
"Billah! No one else. I shall buy you for myself alone."
"Caveat emptor," advised the girl.
"I do not understand, bint," said Atewy.
"You will if you ever buy me. And when you call me bint, smile. It doesn't sound like a nice word."
Atewy grinned. He translated what she had said to the sheykh, and they both laughed. "The Narrawia would be good to have in the beyt of Ab el-Ghrennem," said the sheykh, who had understood nothing of what Atewy had said to Rhonda. "When we are through with this expedition, I think that I shall keep them both; for I shall be so rich that I shall not have to sell them. This one will amuse me; she hath a quick tongue that is like aud in tasteless food."
