The composition of both samples corresponded well with 

 their represented percentage of potassium oxide. 



Their main constituents were chloride of potassium from 

 83 to 84 per cent. ; and chloride of sodium or common salt 

 from 10 to 12 per cent. 



The ton of 2,000 pounds, sold in small lots at 60 dollars 

 currency, which amounts to 5.8 cents per pound of potassium 

 oxide. 



This high grade muriate of potash is one of the cheapest 

 potash sources we have at present at our disposal. 



Artificial Kainit. 



The analytical results of sample No. I. confirm the amount 

 of potassium oxide represented, whilst in sample No. II. 

 there is a deficiency of from one to two per cent, of that 

 substance. 



The difference between the actual amount noticed and the 

 one represented, is, however, so small, that variations in 

 moisture mav account for the result. 



Dealers in fertilizers ought to state the guaranteed composi- 

 tion with refere7ice to the particular percentage of moisture to 

 which the statement applies. 



Farmers do well to insist on specifications of this kind ; for 

 it is the only safe way to secure a mutually satisfactory 

 understanding in case of complaints. 



A careful consideration of the various constituents of the 

 above compounds and their mutual chemical relations to each 

 other leaves no doubt about the fact that the potassium is here 

 present in two different forms ; namely, as potassium sulphate 

 and as potassium chloride.
