“ As Krai retraced his steps through the forest, his thoughts were far away. They reached back across the millions of miles of emptiness he had traversed to come here, back to his own people. They had been doomed; extinction facing them from over-population and lack of water. Mars was nearing the end, and its mighty race seemed about to share the fate of their planet, when a ray of hope came to them. ”

“ Krai was in the open now. With a spurt of speed, accelerated by white-hot hate, the pursuer reached the edge of the forest—too late.
The Martian was nearly to his ship. Another moment and he would be safe. The brute-man hated the ground and feared the incredible powers of the demon-thing too much to risk physical combat. There was only one chance.
Whipping a huge, jagged-edged stone from his girdle, the tree-dweller hurled it with all the energy of his tremendous thews. With deadly accuracy the stone shot through the air. Krai never knew what hit him ”

“ The tree-dweller's first thought was of his mate. But prudence dictated that he remain concealed till the retreating form of the demon disappeared among the trees. Then he searched frantically for his mate. Eventually he found her—crushed among the splinters of their tree-house.
A terrible, burning hate took hold of the savage. An all-consuming hate overcame his instinctive fear of the demon-thing he had seen. ”
