resolved now to reverse as nearly as possible the steps I had taken coming in. Acting on this decision, I started back to that portion of the forest where I had trampled it down. "I found the place without difficulty, stopping once on the way to eat a few berries, and some of the food I carried with me. Then I took a small amount of one of the drugs, and in a few moments the forest trees had dwindled into tiny twigs beneath my feet. "I started now to find the huge incline down which I had fallen, and when I reached it, after some hours of wandering, I followed its bottom edge to where a pile of rocks and dirt marked my former landing-place. The rocks were much larger than I remembered them, and so I knew I was not so large, now, as when I was here before. "Remembering the amount of the drug I had taken coming down, I took now twelve of the pills. Then, in a sudden panic, I hastily took two of the others. The result made my head swim most horribly. I sat or lay down, I forget which. When I looked up I saw the hills beyond the river and forest coming towards me, yet dwindling away beneath my feet as they approached. The incline seemed folding up upon itself, like a telescope. As I watched, its upper edge came into view, a curved, luminous line against the blackness above. Every instant it crawled down closer, more sharply curved, and its inclined surface grew steeper. "All this time, as I stood still, the ground beneath my feet seemed to be moving. It was crawling towards me, and folding up underneath where I was standing. Frequently I had to move to avoid rocks that came at me and passed under my feet into nothingness. "Then, all at once, I realized that I had been stepping constantly backward, to avoid the inclined wall as it shoved itself towards me. I turned to see what was behind, and horror made my flesh creep at what I saw. A black, forbidding wall, much like the incline in front, entirely encircled me. It was hardly more than half a mile away, and towered four or five thousand feet overhead. "And as I stared in terror, I could see it closing in, the line of its upper edge coming steadily closer and lower. I looked wildly around with an overpowering impulse to run. In every direction towered this rocky wall, inexorably swaying in to crush me. "I think I fainted. When I came to myself the scene had not greatly changed. I was lying at the bottom and against one wall of a circular pit, now about a thousand feet
