Carnallit leads in the total quantity mined, followed closely by 

 kainit and hartsalz. The relative quantity of carnallit, however, 

 is decreasing, while that of kainit and sylvinit is increasing. 



These salts were either sold directly from the mines for agricul- 

 tural purposes, or manufactured into more concentrated potash 

 products for use in agriculture, or in the arts and other manu- 

 factures. The greater part of the crude salts manufactured into 

 concentrated products was converted into muriate of potash.
