We have been in a good many strange localities, and have witnessed many impressive scenes both on and under the earth's surface, but we confess that none has ever been comparable to this one. All is dark excepting where our candles cast a faint glimmer about our immediate neighbourhood, and far below we now hear the voices, as well as the rattling of the convicts' chains, more continuously and distinctly, and see numerous lights dancing about fitfully in small clusters. Those are the candles of the convicts who are cutting rock-salt in gangs on the floor of the cave.[75] Continuing our descent down another flight, or rather series of flights, of stairs, we at length arrive at that floor which is about 200 feet from the surface, and there we find ourselves surrounded by homicides, burglars, and the very dregs of the criminal ranks of Roumania. There is no guard with us; and, indeed, of what use would even a small escort be against about two hundred and fifty desperate ruffians armed with pickaxes if they thought fit to unite in an assault upon our little party? They have no such intention, however, and the feeling of the visitor is rather one of pain and sorrow to see so many able-bodied fellows manacled than of fear in their presence.[76] The mode in which they get the salt is by cutting an oblong figure in the floor, deepening this until it resembles a mound, and then cutting the block thus formed transversely into smaller ones and breaking the salt out in lumps. Their work, which is little if at all impeded by their light chains, is performed with pickaxes; and, as already stated, they raise in this manner from 700 to 1,400 kilos (14 to 28 cwt.) per day, which is conveyed to the surface through a special shaft.
