description -
"The sacredness and dignity of salt!  This mineral is like unto the four elements - earth, air, fire and water.  So universal, so necessary to life, it is the fifth element."  Jean de Marcounille, Paris, 1584
 
The story of a basic American industry.  Salt was once placed above the price of rubies. Wars have been fought over it. Everybody uses salt; everybody depends on it ways beyond numbering to enhance health and daily living.
