When I recovered consciousness the light had gone out. There was no sound about me. I shouted up the shaft above and could get no answer. The chamber in which I lay was many times my height and I could make nothing out in the dark hole above. For some hours I scarcely stirred and feared to burn my pocket flash both because it might reveal my presence to lurking enemies and because I wished to conserve my battery against graver need. But no rescue came from my men above. Only recently, after the lapse of years, did I learn the cause of their deserting me. As I lay stunned from my fall, my men, unable to get answer to their shoutings, had given me up for dead. Meanwhile the apparatus which caused the destruction of the German gas had gone wrong. My associates, unable to fix it, had fled from the mine and abandoned the enterprise. After some hours of waiting I stirred about and found means to erect a rough scaffold and reach the mouth of the shaft above me. I attempted to climb, but, unable to get a hold on the smooth wet rock, I gave up exhausted and despairing. Entombed in the depths of the earth, I was either a prisoner of the German potash miners, if any remained alive, or a prisoner of the earth itself, with dead men for company. Collecting my courage I set about to explore my surroundings. I found some mining machinery evidently damaged by the explosion of our gas bombs. There was no evidence of men about, living or dead. Stealthily I set out along the little railway track that ran through a passage down a steep incline. As I progressed I felt the air rapidly becoming colder. Presently I stumbled upon the first victim of our gas bombs, fallen headlong as he was fleeing. I hurried on. The air seemed to be blowing in my face and the cold was becoming intense. This puzzled me for at this depth the temperature should have been above that on the surface of the earth. After a hundred metres or so of going I came into a larger chamber. It was intensely cold. From out another branching passage-way I could hear a sizzling sound as of steam escaping. I started to turn into this passage but was met with such a blast of cold air that I dared not face it for fear of being frozen. Stamping my feet, which were fast becoming numb, I made the rounds of the chamber, and examined the dead miners that were tumbled about. The bodies were frozen. One side of this chamber was partitioned off with some sort of metal wall. The door stood blown open. It felt a little warmer in here and I entered and closed the door. Exploring the room with my dim light I found one side of it filled with a row of bunks--in each bunk a corpse. Along the other side of the room was a table with eating utensils and back of this were shelves with food packages.
