The more I thought of it, the more sure I became that in any case I must perish, A man in a block of ice could have no chance of life. And Agnes! Oh, Heavens! what demon of the ice had leagued with old Havelot to shut me up in this frozen prison? For a long time I continued to walk, beat my body with my arms and stamp my feet. The instinct of life was strong within me. I would live as long as I could, and think of Agnes. When I should be frozen I could not think of her. Sometimes I stopped and listened. I was sure I could hear noises, but I could not tell whether they were above me or not. In the centre of the ice-barrier, about four feet from the ground, was a vast block of the frozen substance which was unusually clear and seemed to have nothing on the other side of it; for through it I could see flickers of light, as though people were going about with lanterns. It was quite certain that the accident had been discovered; for, had not the thundering noise been heard by persons outside, the workmen would have seen what had happened as soon as they came into the tunnel to begin their afternoon operations. At first I wondered why they did not set to work with a will and cut away this barrier and let me out. But there suddenly came to my mind a reason for this lack of energy which was more chilling than the glistening walls around me: Why should they suppose that I was in the ice-chamber? I was not in the habit of coming here very often, but I was in the habit of wandering off by myself at all hours of the day. This thought made me feel that I might as well lie down on the floor of this awful cave and die at once. The workmen might think it unsafe to mine any further in this part of the glacier, and begin operations at some other point. I did sit down for a moment, and then I rose involuntarily and began my weary round. Suddenly I thought of looking at my watch. It was nearly five o'clock. I had been more than four hours in that dreadful place, and I did not believe that I could continue to exercise my limbs very much longer. The lights I had seen had ceased. It was quite plain that the workmen had no idea that any one was imprisoned in the cave.
