Salt-mines Salt, how Obtained. 153 





32. The salt-mines in the northern 

 part of Austria are about 1,000 feet in 

 depth and two miles in length. They con- 

 tain many great rooms, galleries, and pas- 

 sages, all cut out by the miners. There are 

 valuable salt-mines also in Russia, Eng- 

 land, Germany, Italy, and Spain.

 mines, but also from the water of the 

 ocean, salt springs and wells, which you
