In a few minutes we touched bottom, or rather, by something like instinct, the machine stopped just as we reached the base of the shaft, and allowed us to glide off gently on the firm earth. We are now at the first stage of our journey, having descended something over two hundred feet. The ramifications of the various tunnels are so intricate and extensive that they may be said to resemble more the streets of a large city than a series of excavations made in the bowels of the earth. These subterranean passages are named after various kings and emperors, and diverge in every direction, opening at intervals into spacious caverns and apartments, and undermining the country for a distance of several miles. Some of them pass entirely under the town of Wieliczka. In general they are supported by massive beams of wood, and where the overhanging masses of salt require a still stronger support they are sustained by immense columns of the original stratum. In former times almost all the passages were upheld by pillars of salt, but wherever it has been practicable these have been removed and beams of timber substituted. The first stratum consists of an amalgam of salt and dark-colored clay. Deeper down come alternate strata of marl, pebbles, sand, and blocks of crystal salt. The inferior or green salt is nearest to the surface; the crystal, called schilika, lies in the deeper parts.
From the subordinate officer sent by the Inspector-General to accompany us I learned many interesting particulars in reference to the manner of procuring the salt. He also told some amusing legends of the prominent places, and furnished me with some statistics, which, if true, are certainly wonderful. For instance, to traverse the various passages and chambers embraced within the four distinct stories of which the mines consist, and see every object of interest, would require three weeks. The aggregate length of the whole is four hundred English miles; the greatest depth yet reached is two thousand three hundred feet. The number of workmen employed in the various operations underground, exclusive of those above, is upward of a thousand. The amount of salt annually dug out is two hundred millions of pounds, which, at the average market value, would be worth ten millions of gulden. Immense as this yield is, it is inconsiderable, taking into view the unlimited capacity of the mines. With proper machinery and a judicious investment of labor the quantity of salt that might be excavated is almost beyond conjecture.
It is natural to suppose that the air in these vast subterranean passages must be impure, and consequently deleterious to health. Such, however, does not appear to be the case. It is both dry and pure, and, so far as I could judge by breathing it, not in the least oppressive. The miners are said to be remarkable for longevity. Several of them, according to the guide, have worked in the mines for forty years, and have never been sick a day. The equability of the temperature is probably conducive to health. Only a few degrees of variation are shown by the thermometer between summer and winter. It is true that in some of the deepest recesses, which are not sufficiently ventilated, hydrogen gas occasionally collects. In one instance it caught fire, and cost the loss of many lives, but precautions have since been taken to prevent similar accidents.
I was greatly impressed by the profound silence of these vast caverns. When we stood still the utter absence of sound was appalling. The falling of a pin would have been a relief. Not even the faintest vibration in the air was perceptible. No desert could be more silent, no solitude more awful. I stood apart from the guides and lamp-bearers in a separate vault, at the distance of a few hundred feet, in order that I might fully appreciate this profound inertion, and it really seemed as if the world were no more.
From some of these tunnels we emerged into open caverns, where a few workmen were employed at their dreary labors. I was surprised that there were not more to be seen, but was informed that they are scattered in small parties through miles of earth, so that the number is not apparent to the casual visitor. As we approached the places where they are at work the dull clicking of the picks and hammers produced a singular effect through the vast solitudes, as if the gnomes, supposed to inhabit gloomy pits, were busily engaged at their diabolical arts.
We came suddenly upon one group of workmen, under a shelving ledge, who were occupied in detaching masses of crystallized salt from a cleft in which they worked. They were naked to the middle, having nothing on but coarse trousers and boots, and wrought with their crowbars and picks by the light of a few grease-lamps held by grimy little boys, with shaggy heads,—members, no doubt, of the same subterranean family.
Some of the men were lying on their backs, punching away with tremendous toil at the ragged masses of salt overhead, their heads, faces, and bodies glittering with the showers of salt grit that fell upon them, while others stood up to their armpits in dark holes delving into the lower crevices. Seeing our lights, they stopped to gaze at us. Was it possible they were human beings, these bearded, shaggy, grimy-looking monsters? Surely, if so, they well represented the infernal character of the place. Never upon earth (the surface of it I mean) had I seen such a monstrous group,—shocks of hair all powdered with salt, glaring eyeballs overhung by white lashes flashing in the fitful blaze of lamps, brawny forms glittering with crystal powder, and marked by dark currents of sweat. No wonder I stared at them with something akin to distrust. They might be monsters in reality, and take a sudden notion to hurl me into one of their infernal pits by way of pastime, in which case the only consolation would be, that where there was such an abundance of salt there would be no difficulty about the preservation of my remains.
After all, there was something sad in the condition of these poor wretches, shut out from the glorious light of day, immured in deep dark pits, hundreds of feet underground, rooting, as it were, for life in the bowels of the earth. Surely the salt with which other men flavor their food is gathered with infinite toil, and mingled with bitter sweat!
