The girl, clinging desperately to the noose, strained every muscle to hold the great weight dangling at the lower end of the rope.
Usanga, all unconscious of what was going on behind him, drove the plane higher and higher into the air.
Tarzan glanced downward. Below him the tree tops and the river passed rapidly to the rear and only a slender grass rope and the muscles of a frail girl stood between him and the death yawning there thousands of feet below.
It seemed to Bertha Kircher that the fingers of her hands were dead. The numbness was running up her arms to her elbows. How much longer she could cling to the straining strands she could not guess. It seemed to her that those lifeless fingers must relax at any instant and then, when she had about given up hope, she saw a strong brown hand reach up and grasp the side of the fuselage. Instantly the weight upon the rope was removed and a moment later Tarzan of the Apes raised his body above the side and threw a leg over the edge. He glanced forward at Usanga and then, placing his mouth close to the girl's ear he cried: "Have you ever piloted a plane?" The girl nodded a quick affirmative.
"Have you the courage to climb up there beside the black and seize the control while I take care of him?"
The girl looked toward Usanga and shuddered. "Yes," she replied, "but my feet are bound."
Tarzan drew his hunting knife from its sheath
