A RETIRED DIRECTOR.
"The workmen and their families assemble in their holiday dress, and when the music begins the whole party indulges in the Polish national dance. It is a strange spectacle, this scene of revelry five hundred feet below the surface of the earth, and probably among the sights that do not come often before the Imperial eyes. These spectacles must be arranged to order, and for weeks before an Imperial or Royal visit a great many hands are engaged in making the necessary preparations. From all I heard of these festivals, I would willingly travel many hundred miles to see one of them.
"By means of the illuminating materials that we brought with us, we were able to get an approximate idea of the character of one of these gala spectacles. After our last Bengal-light had been burned, we continued our journey, descending to the third story by many devious ways, and finally halting in a chamber whose roof was not less than a hundred feet above us.
"'Do you know where you are?' said our guide.
"Of course we answered that we did not.
"'Well,' said he, 'you are directly beneath the lake which we sailed over in a boat a little while ago. If it should break through we should all be drowned, dead.'
"We shuddered to think what might be our fate if the lake should spring a leak. It did break out at one time and flooded many of the galleries, and for a long while work in all the lower part of the mine was suspended. There have been several fires, some of them causing the loss of many lives; but, on the whole, considering the long time the mine has been opened and the extent of the works, the accidents have been few.
"The deepest excavation in the mine is nearly seven hundred feet below the level of the sea. We did not go there, in fact we did not go below the third story, as we had seen quite enough for our purposes, and besides we had only a limited time to stay in the mine. As we came up again to daylight, hoisted in the same sort of chairs as those by which we descended, we made a final inspection of the salt which comes from the mine.
"'There are three kinds of salt,' said the guide. 'One that is called green salt contains five or six per cent. of clay, and has no transparency; it is cut into blocks and sent to Russia exactly as it comes from the mine. The second quality is called spiza, and is crystalline and mixed with sand; and the third is in large masses, perfectly transparent, having no earthy matter mingled with it. The salt is found in compact tertiary clays that contain a good many fossils; the finest salt is at the lowest levels, and the poorest at the higher ones.'
