Ina general way the salt - mines ofWieliczka may be said to be near-ly two miles square; but the endsof some of the passages are morethan two miles from the entranceof the nearest shaft. The entiretown of Wieliczka lies above themines which give occupation to itsinhabitants. There is probably more tim-ber beneath the surface at Wie-liczka than above it, as the roofsof the numerous passages are sup-ported by heavy beams; and the same is the case with the smaller the larger halls such support would be insufficient, and immense col-umns of salt are left in position.
