This saline belongs to the products of the " German 

 Potash Industry" at Strassfurt. It contains from 15 to 

 16 per cent, of sulphate of potassa, besides sulphate of lime 

 (gypsum), sulphate of magnesia, and chloride of sodium 

 (common salt), etc. A careful trial of the article upon hill 

 pastures, as a top-dressing, in connection with fine ground 

 bones, deserves attention. It sold at $14 per ton of 2,000 

 pounds, on board of cars in Boston. 



Sold at 22 cents per bushel. 

 The material is a fair sample of its kind.
