The difference in nioisture in the above analyses explains 

 somewhat the difference in potash. 



Wood Ashes. (Two samples.) 



[Sent on from South Deerfield Farmers' Club.] 



Pounds per Hundred 



Moisture at lOO'' C, 

 Phosphoric acid, 

 Calcium oxide, . 

 Magnesium oxide. 

 Potassium oxide, 

 Insoluble matter. 



The first article is evidently a partly leached wood ash. 

 The two samples differ mainly in regard to their relative amount 

 of potash. This difference expressed in money value amounts 

 to from 26 to 27 cents per hundred weight of ashes, allowing 

 5.5 cents per pound of potassium oxide in case of wood ash.
