“Going? I am going wherever she is going. I’ll follow her to the end of the moon if necessary, though the surface be everywhere as bleak as our own north pole.” “Well,” he replied, “if it is such a desperate case as that, I’ll have to go along to take care of you.” I found that when such a woman beckons and such a voice calls there is but one thing to do. The sirens were not to be mentioned in comparison. Twenty thousand hurricanes could not have prevented me from attempting to follow where she led as long as I had breath. We reached the ground in safety, and with the greatest difficulty made our way in the footsteps of our guide, leaving all our possessions behind us, to the doctor’s murmured regret. And now the words of the singer seemed to take on a joyous meaning, and we could almost distinguish her invitation to follow her to a place where the wind did not blow and where our present troubles would be over. She kept well in the lead but walked only as fast as our strength would allow, looking back constantly to encourage us with her smile and ravishing one heart at least with the melody of her song. Presently we came to the edge of an immense crater, hundreds of feet deep and as empty and cold as all the others we had seen on the moon. Instead of going around this, our leader chose a narrow ravine and took us down the steep side to the bottom of the crater. We supposed she did this just to give us protection from the wind, and we were very much sheltered, but she did not stop here. Entering one of the many fissures in the rocks, she led us into a narrow passage whose floor descended so rapidly and whose solid roof shut out the light so quickly that in ordinary circumstances we would have hesitated about proceeding. But, although it was soon absolutely dark, we kept on, guided by that marvelous voice, now our sole inspiration. “Come, come, fear no harm,” it seemed to say, and we were content to follow blindly, even the doctor no longer objecting. [Illustration: “POURING FORTH HER VOICE IN THAT EXQUISITE SONG.”] How many hours we proceeded in this way, going down, down, all the time, toward the center of the globe, I have no means of telling; but I distinctly remember that we began, after a time, to find, to our great joy, that the air was becoming denser and we could breathe quite freely. This gave us needed strength and justified the faith with which our mysterious deliverer had filled us.
