"As the trap-door closed above us, I confess to a rather uncanny feeling. Below us gleamed the lights in the hands of the lamp-bearers, but above there was a darkness that seemed as though it might be felt, or sliced off with a knife. Nobody spoke, and the attention of all seemed to be directed to hanging on to the rope. Of course the uppermost question in everybody's mind was, 'What if the rope should break?' It doesn't take long to answer it; the individuals hanging in that cluster below the gloomy trap-door would be of very little consequence in a terrestrial way after the snapping of the rope. [Illustration: DESCENDING THE SHAFT.] "We compared notes afterwards, and found that our sensations were pretty much alike. The general feeling was one of uncertainty, and each one asked himself several times whether he was asleep or awake. Fred said a part of the journey was like a nightmare, and the Doctor said he had the same idea, especially after the noise of the machinery was lost in the distance and everything was in utter silence. For the first few moments we could hear the whirring of the wheel and the jar of the machinery; but very soon these sounds disappeared, and we glided gently downward, without the least sensation of being in motion. It seemed to me not that we were descending, but that the walls of the shaft were rising around us, while our position was stationary. "Contrary to expectation, we found the air quite agreeable. The official who accompanied us said it was peculiarly conducive to health; and many of the employés of the mines had been at work there forty or fifty years, and had never lost a day from illness. We had supposed it would be damp and cold, but, on the contrary, found it dry and of an agreeable temperature, which remains nearly the same all through the year. No doubt the salt has much to do with this healthy condition. Occasionally hydrogen gas collects in some of the shafts which are not properly ventilated, and there have been explosions of fire-damp which destroyed a good many lives. These accidents were the result of carelessness either of the miners or their superintendents, and since their occurrence a more rigid system of inspection has been established. [Illustration: LAMP-BEARERS.] "We stopped at the bottom of the shaft, which is about three hundred feet deep; there we were released from our fastenings and allowed to use our feet again. Then we were guided through a perfect labyrinth of passages, up and down ladders, along narrow paths, into halls spacious enough for the reception of an emperor, and again into little nooks where men were occupied in excavating the salt. For several hours we wandered there, losing all knowledge of the points of compass, and if we had been left to ourselves our chances of emerging again into daylight would have been utterly hopeless.
