I have not the slightest idea how long I remained upon this barren mountain top, but after hours of mental torture I suddenly caught sight of the air ship flying toward me high above the desert plain. My heart gave one great leap of joy, and then I relapsed into a dreadful fear lest Torrence should not see me. In an instant I had pulled off my shirt and was waving it frantically. I watched for an answer, but no, he was not on the lookout; still I would not relax my efforts until every hope had passed. I shouted, I roared, I waved my shirt and coat frantically. I ran as fast as possible about the rock to attract his attention. I took off one of my boots and beat upon the water barrel; but still he did not signal in reply. I was beside myself with horror at the thought of being left alone in this mysterious world. Surely though, even if he passed he would return to look for me. On and on came the air ship, as magnificently as ever. He had managed then without me to repair the damage, for never had she sailed more splendidly, more superbly than now. Nearer and nearer she came. What if the terrible noise I was making should arouse my captors below, and they should seize and carry me down to their own mysterious regions again? The thought sickened me, yet I dared not cease my bellowing and shouting for a single instant. So near the mountain, and yet no signal. Oh, horror! was he going to leave me? He had reached a point directly above my head; and now he could not see me if he were on deck. It was my last hope. "Torrence! Torrence!" I cried, as if my heart would break. Oh God! The agony of that minute as I saw the vessel quickly drift away upon her course, leaving me lost and alone or in the companionship of men whose methods of life were inscrutable. Once more I yelled. It was my last and greatest effort—and—what did I see——? Yes, it had borne fruit. The great machine paused in its flight, and Torrence looked over the rail. I waved, my shirt frantically. He saw me—he heard me. The motion was reversed; and then, like some majestic bird, she settled earthward. It would be useless to attempt a description of my feelings at that moment. I cannot even realize them myself. I only know that when the huge monster touched the mountain top I sprang upon her side like a madman, and clutched wildly at the footboard before the ladder was dropped. In a minute I was aboard; the rail snapped to behind me, and we were sailing tranquilly away from the horrible scenes that had so beset us. But before a hundred yards had been placed between us and those awful cliffs, a body of men had ranged themselves in line to witness our departure. I do not pretend to account for what I saw in those rock-bound halls; if this were fiction I would doubtless do so; but as it is, I can only offer the suggestions already made, be they worth what they may.
