Some of the tribesmen shielded their faces against the evil eye while others muttered anxiously. A few turned as if to flee back to their own land but at a sharp command from Dick they followed grumbling.

Dick halted his riders and they ate a hasty lunch while shielding themselves in the shadow of their horses.

Late that afternoon they came to the oasis in the desert. The men threw themselves flat on their stomachs by the spring, dipping up the water in their hands and drinking with loud sucking noises. It was hard for both man and beast to restrain the desire to overdo, for their parched throats seemed never to get enough.

As soon as the quickly prepared meal was over, the men stretched out on the green grass beneath the palms and slept.

Long before daylight the tribesmen were up, making ready for the second day's march toward the jungle. Dick and Dan were weary and sore from the journey but there were no complaints from either of them. They swung into their saddles and taking the lead, raced their horses over the desert, making the most of the cool morning, knowing that as soon as the sun rose the heat would be almost unbearable.

It was late on the third day when they reached the lowlands which lay at the beginning of the jungle. Already the atmosphere had changed. It was oppressive and humid. Directly in front of them was a path leading to the wilderness of trees and overgrowing trailing plants. The stars were just appearing in the sky and Dick ordered his men to make camp, feeling safer to sleep in the open. He put Kurt and Kurul, his most trustworthy warriors, to stand guard. But Dick could not sleep. The sound of jungle life came to him, the sharp cries of night birds, the yelping of wild animals. The Boy King felt the menace of the jungle.

But after hours of listening the sounds seemed to grow fainter as if the wild life were going far, far away. His eyes closed. But just as he might have dropped off to sleep, he was awakened by Dan's hand on his face.

"I don't want to frighten you, Dick, but do you see those two greenish lights at the edge of the trees? Look!"

"They are probably stars," replied Dick sleepily. Dick rubbed his tired eyes and sat up. Dan pointed out the glowing sparks. The boys did not move, for they saw that Kurt and Kurul were aware of the intruder. They stood motionless near a jungle tree.

"It's a leopard, Dick, I'm sure of it," said Dan. "Where's your Arab gun?"
