brightly. This, I have explained, was caused by the phosphorescent radiation that apparently emanated from every particle of mineral matter in this universe. "As we advanced, many other tunnels crossed the one we were traveling. And now, occasionally, we passed other people, the men dressed similarly to Lylda, but wearing their hair chopped off just above the shoulder line. "Later, I found that the men were generally about five and a half feet in stature: lean, muscular, and with a grayer, harder look to their skin than the iridescent quality that characterized the women. "They were fine-looking chaps these we encountered. All of them stared curiously at me, and several times we were held up by chattering groups. The intense whiteness of my skin, for it looked in this light the color of chalk, seemed to both awe and amuse them. But they treated me with great deference and respect, which I afterwards learned was because of Lylda herself, and also what she told them about me. "At several of the intersections of the tunnels there were wide open spaces. One of these we now approached. It was a vast amphitheater, so broad its opposite wall was invisible, and it seemed crowded with people. At the side, on a rocky niche in the wall, a speaker harangued the crowd. "We skirted the edge of this crowd and plunged into another passageway, sloping downward still more steeply. I was so much interested in the strange scenes opening before me that I remarked little of the distance we traveled. Nor did I question Lylda but seldom. I was absorbed in the complete similarity between this and my own world in its general characteristics, and yet its complete strangeness in details. "I felt not the slightest fear. Indeed the sincerity and kindliness of these people seemed absolutely genuine, and the friendly, naïve, manner of my little guide put me wholly at my ease. Towards me Lylda's manner was one of childish delight at a new-found possession. Towards those of her own people with whom we talked, I found she preserved a dignity they profoundly respected. "We had hardly more than entered this last tunnel when I heard the sound of drums and a weird sort of piping music, followed by shouts and cheers. Figures from behind us scurried past, hastening towards the sound. Lylda's clasp on my hand tightened, and she pulled me forward eagerly. As we advanced the crowd became denser, pushing and shoving us about and paying little attention to me.
