Dirk Peters, a man named Wilson Allen, and myself were on the right of our companions, examining, as we went along, the singular stratification of the precipice which overhung us. A fissure in the soft rock attracted our attention. It was about wide enough for one person to enter without squeezing, and extended back into the hill some eighteen or twenty feet in a straight course, sloping afterward to the left. The height of the opening, as far as we could see into it from the main gorge, was perhaps sixty or seventy feet. There were one or two stunted shrubs growing from the crevices, bearing a species of filbert, which I felt some curiosity to examine, and pushed in briskly for that purpose, gathering five or six of the nuts at a grasp, and then hastily retreating. As I turned, I found that Peters and Allen had followed me. I desired them to go back, as there was not room for two persons to pass, saying they should have some of my nuts. They accordingly turned, and were scrambling back, Allen being close to the mouth of the fissure, when I was suddenly aware of a concussion resembling nothing I had ever before experienced, and which impressed me with a vague conception, if indeed I then thought of anything, that the whole foundations of the solid globe were suddenly rent asunder, and that the day of universal dissolution was at hand. CHAPTER XXI. As soon as I could collect my scattered senses, I found myself nearly suffocated, and grovelling in utter darkness among a quantity of loose earth, which was also falling upon me heavily in every direction, threatening to bury me entirely. Horribly alarmed at this idea, I struggled to gain my feet, and at length succeeded. I then remained motionless for some moments, endeavouring to conceive what had happened to me, and where I was. Presently I heard a deep groan just at my ear, and afterward the smothered voice of Peters calling to me for aid in the name of God. I scrambled one or two paces forward, when I fell directly over the head and shoulders of my companion, who, I soon discovered, was buried in a loose mass of earth as far as his middle, and struggling desperately to free himself from the pressure. I tore the dirt from around him with all the energy I could command, and at length succeeded in getting him out.
