And here, evidently halted in flight by this insurmountable break in the ledge, stood the object of the creature’s attack—a girl cowering upon the narrow platform, her face buried in her arms, as though to shut out the sight of the frightful death which hovered just above her. The dragon was circling lower, and seemed about to dart in upon its prey. There was no time to be lost, scarce an instant in which to weigh the possible chances that I had against the awfully armed creature; but the sight of that frightened girl below me called out to all that was best in me, and the instinct for protection of the other sex, which nearly must have equaled the instinct of self-preservation in primeval man, drew me to the girl’s side like an irresistible magnet. Almost thoughtless of the consequences, I leaped from the end of the ledge upon which I stood, for the tiny shelf twenty feet below. At the same instant the dragon darted in toward the girl, but my sudden advent upon the scene must have startled him for he veered to one side, and then rose above us once more. The noise I made as I landed beside her convinced the girl that the end had come, for she thought I was the dragon; but finally when no cruel fangs closed upon her she raised her eyes in astonishment. As they fell upon me the expression that came into them would be difficult to describe; but her feelings could scarcely have been one whit more complicated than my own—for the wide eyes that looked into mine were those of Dian the Beautiful. “Dian!” I cried. “Dian! Thank God that I came in time.” “You?” she whispered, and then she hid her face again; nor could I tell whether she were glad or angry that I had come. Once more the dragon was sweeping toward us, and so rapidly that I had no time to unsling my bow. All that I could do was to snatch up a rock, and hurl it at the thing’s hideous face. Again my aim was true, and with a hiss of pain and rage the reptile wheeled once more and soared away. Quickly I fitted an arrow now that I might be ready at the next attack, and as I did so I looked down at the girl, so that I surprised her in a surreptitious glance which she was stealing at me; but immediately, she again covered her face with her hands. “Look at me, Dian,” I pleaded. “Are you not glad to see me?” She looked straight into my eyes. “I hate you,” she said, and then, as I was about to beg for a fair hearing she pointed over my shoulder. “The thipdar comes,” she said, and I turned again to meet the reptile. So this was a thipdar. I might have known it. The cruel bloodhound of the Mahars. The long-extinct pterodactyl of the outer world. But this time I met it with a weapon it never had faced before. I had selected my longest arrow, and with all my strength had bent the bow until the very tip of the shaft rested upon the thumb of my left hand, and then as the great creature darted toward us I let drive straight for that tough breast.
