I took with me a lantern and went around the chamber, which was now twenty-five or thirty feet in diameter, examining the new inroads which had been made upon its walls. There was a tunnel commenced opposite the one by which the chamber was entered, but it had not been opened more than a dozen feet, and it seemed to me that the men had not been working with any very great energy. I wanted to see a continuous stream of ice-blocks from that chamber to the mouth of the shaft.
While grumbling thus I heard behind me a sudden noise like thunder and the crashing of walls, and, turning quickly, I saw that a portion of the roof of the chamber had fallen in. Nor had it ceased to fall. As I gazed, several great masses of ice came down from above and piled themselves upon that which had already fallen.
Startled and frightened, I sprang toward the opening of the entrance tunnel; but, alas! I found that that was the point where the roof had given way, and between me and the outer world was a wall of solid ice through which it would be as impossible for me to break as if it were a barrier of rock. With the quick instinct which comes to men in danger I glanced about to see if the workmen had left their tools; but there were none.
They had been taken outside. Then I stood and gazed stupidly at the mass of fallen ice, which, even as I looked upon it, was cracking and snapping, pressed down by the weight above it, and forming itself into an impervious barrier without crevice or open seam.
Then I madly shouted. But of what avail were shouts down there in the depths of the earth? I soon ceased this useless expenditure of strength, and, with my lantern in my hand, began to walk around the chamber, throwing the light upon the walls and the roof. I became impressed with the fear that the whole cavity might cave in at once and bury me here in a tomb of ice. But I saw no cracks, nor any sign of further disaster. But why think of anything more? Was not this enough? For, before that ice-barrier could be cleared away, would I not freeze to death?
I now continued to walk, not because I expected to find anything or do anything, but simply to keep myself warm by action. As long as I could move about I believed that there was no immediate danger of succumbing to the intense cold; for, when a young man, traveling in Switzerland, I had been in the cave of a glacier, and it was not cold enough to prevent some old women from sitting there to play the zither for the sake of a few coppers from visitors. I could not expect to be able to continue walking until I should be rescued, and if I sat down, or by chance slept from exhaustion, I must perish.
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.
But soon after I had come to this conclusion I saw through the clear block of ice a speck of light, and it became stronger and stronger, until I believed it to be close to the other side of the block. There it remained stationary; but there seemed to be other points of light which moved about in a strange way, and near it. Now I stood by the block watching. When my feet became very cold, I stamped them; but there I stood fascinated, for what I saw was truly surprising. A large coal of fire appeared on the other side of the block; then it suddenly vanished and was succeeded by another coal. This disappeared, and another took its place, each one seeming to come nearer and nearer to me. Again and again did these coals appear. They reached the centre of the block; they approached my side of it. At last one was so near to me that I thought it was about to break through, but it vanished. Then there came a few quick thuds and the end of a piece of iron protruded from the block. This was withdrawn, and through the aperture there came a voice which said: “Mr. Cuthbert, are you in there?” It was the voice of Agnes!
