"For some moments we sat looking at each other in wonderment. Then she smiled and held out her hand, palm up, speaking a few words as she did so. Her voice was soft and musical, and the words of a peculiar quality that we generally describe as liquid, for want of a better term. What she said was wholly unintelligible, but whether the words were strange or the intonation different from anything I had ever heard I could not determine. "Afterwards, during my stay in this other world, I found that the language of its people resembled English quite closely, so far as the words themselves went. But the intonation with which they were given, and the gestures accompanying them, differed so widely from our own that they conveyed no meaning. "The gap separating us, however, was very much less than you would imagine. Strangely enough, though, it was not I who learned to speak her tongue, but she who mastered mine." The Very Young Man sighed contentedly. "We became quite friendly after this greeting," resumed the Chemist, "and it was apparent from her manner that she had already conceived her own idea of who and what I was. "For some time we sat and tried to communicate with each other. My words seemed almost as unintelligible to her as hers to me, except that occasionally she would divine my meaning, clapping her hands in childish delight. I made out that she lived at a considerable distance, and that her name was Lylda. Finally she pulled me by the hand and led me away with a proprietary air that amused and, I must admit, pleased me tremendously. "We had progressed through the woods in this way, hardly more than a few hundred yards, when suddenly I found that she was taking me into the mouth of a cave or passageway, sloping downward at an angle of perhaps twenty degrees. I noticed now, more graphically than ever before, a truth that had been gradually forcing itself upon me. Darkness was impossible in this new world. We were now shut in between narrow walls of crystalline rock, with a roof hardly more than fifty feet above. "No artificial light of any kind was in evidence, yet the scene was lighted quite 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.
