“Lie down flat at full length, Nah-ee-lah,” I directed her, “and hold this pole securely with both hands. You will only have to keep it from toppling to the sides or outward, and to that, I think, your strength is equal. While you hold it, I will descend to the mouth of the tunnel and raise one of the regular hooked poles which you say should be deposited there. If they are not, I believe that I can hold our own pole securely from below while you descend.” She looked over into the vast abyss below and shuddered. “I can hold it at the top,” she said, “if the bottom does not slip from the ledge.” “That is a chance that I shall have to take,” I replied, “but I will descend very carefully and I think there will be little danger upon that score.” I could see, upon a more careful examination of the ledge below, that there was some danger of an accident such as she suggested. Nah-ee-lah took her position as I had directed and lay grasping the pole securely in both hands at the rim of the crater, which was absolutely perpendicular at this point, and I prepared to make the perilous descent. I can assure you that my sensations were far from pleasurable as I looked over into that awful abyss. The crater itself was some four or five miles in diameter, and, as I had every reason to suspect, extended fully two hundred and fifty miles through the lunar crust to the surface of the Moon. It was one of the most impressive moments of my life as I clung balancing upon the edge of that huge orifice, gazing into the silent, mysterious depths below. And then I seized the pole very gently and lowered myself over the edge. “Courage, Julian!” whispered Nah-ee-lah; “I shall hold very tight.” “I shall be quite safe, Nah-ee-lah,” I assured her. “I must be safe, for if I am not, how are you to reach the ledge and Laythe?” As I descended very slowly I tried not to think at all, but to exclude from my mind every consideration of the appalling depths beneath me. I could not have been more than two feet from the ledge when the very thing that we both tried so hard to guard against transpired—a splintered fragment of the pole’s butt crumpled beneath my weight and that slight jar was just sufficient to start the base of my precarious ladder sliding toward the edge of the narrow projection upon which I had rested it, and beyond which lay eternity. Above me I heard a slight scream and then the pole slipped from the ledge and I felt myself falling. It was over in an instant. My feet struck the ledge and I threw myself within the mouth of the tunnel. And then, above me, I heard Nah-ee-lah’s voice crying in agonized tones: “Julian! Julian! I am falling!”
