* * * * * I found myself a full head and shoulders taller than Polter. And he was tiring, panting heavily. His face was cut and bleeding from the blows of my fists. The rock I heaved struck his shoulder. He roared, head down, and bored into me. He was heavier than I. His weight flung me back. My foot slid on the loose stones of the gully floor. I did not know that Babs, Alan and their father were huddled under those stones! My back struck the opposite wall. Polter's upflung knee caught me in the stomach, all but knocking the breath from me. He was desperate, oblivious to the closing walls. And as he flung his arms with a grip about my neck, hanging, trying to bear me down, I saw in his blazing dark eyes what seemed the light of suicide. I think that then, with a sudden frenzied madness he realized that he was beaten. And tried to pull us to the ground and let the walls crush us. I summoned all my remaining strength and heaved us forward. I broke his hold. His body was jammed back against a lowering wall. Its top seemed almost at our knees. I shoved frantically. He fell backward and I jumped after him. We were on a great rocky plateau. But it was shrinking, crawling into itself. Spots of light were in the murk overhead; there seemed a distant circular horizon of emptiness around us. Polter was lying in a heap. But it was trickery, for as I incautiously bent over him his hand crashed a rock against my head. I reeled, with all the world turning black, but did not fall. There was a horrible instant when my senses were going, but I fought to hold them. Blood from a wound on my forehead was streaming in my eyes. I was staggering. Then I realized I was grimly tossing my head, shaking the blood away; and little by little my sight came back. Polter was on his feet, rushing me. His fist came with an upward swing at my chin, but I ducked my head aside at the last moment. And suddenly, fighting up there in the open, my mind envisaged how gigantic we were! This was a great upland plateau, rounded with miles of distance and a shadowy, dimly radiant abyss beyond its circular horizon. And I was a thousand feet or more tall! A titan, looming here in the sky!... * * * * * My fist quite unexpectedly caught Polter's jaw. His simultaneous swing went wild, though I leaped backward from it. He staggered, and his arms dropped to his sides. I was crouched forward, guarded, watching him while I gasped for breath. There was the briefest of instants when an expression of vague surprise swept his face. But I had not knocked him out.
