t was then that the thin cloak of civilization dropped from Aaron Carruthers' back. He became in a single moment an animal fighting for his mate. With a snarl equally vicious as that of the gorilla pawing at the helpless girl, he lunged forward.
Mouthing his rage, the gorilla flung the earth man to the ground. Carruthers came up frothing at the mouth. With grim intensity he fastened himself to the animal's free arm. The raging mammal staggered helplessly under the extra burden and dropped the girl to concentrate his fury on the man. It raised a hairy arm aloft for the smashing blow. Instinctively Carruthers released his hold.
At that very moment the electron lurched sickeningly, causing them both to lose their footing. The violent upheaval sent Carruthers one way and the gorilla the other. While the man stumbled to his feet to resume battle he saw the infuriated monster stagger over the edge of the plateau wall into a sheer drop of a thousand feet.
Starkly through the night came the growling roars of the giant beasts from the jungles below. Nanette fluttered to his side. Her dress was torn and dragged on the ground. For all her disheveled appearance she was still beautiful to look upon. Forgetful of the danger on all sides of him, the animal in Carruthers saw in her pitifully half-clad body the same thing that the beast had desired. His head whirled hotly.
"Aaron!" she pleaded as his arm reached out to clutch her.
Hungrily he drew her to him. The pale light of the electron moon mingled with the roaring blast of the flames. Madness inflamed his heart and pounded his blood.
"Don't, Aaron," protested the girl, trying to free herself.
