70 THE CONNECTICUT AGRICULTURAL 



large number of analyses would be necessary to decide whether 

 this difference is more than an accidental one. Canada ashes 

 apparently have rather less potash and phosphoric acid than 

 clean burned birch, hickory and oak, and less than the average of 

 ashes from house fires as found by Dr. Storer. 



A cord of hickory wood, as we are informed by wood dealers 

 in this city, weighs from 3400 to 4300 lbs. and on the average 

 about 3500 lbs. A cord of oak wood weighs from 2300 to 2400 

 lbs. The weight of birch and chestnut wood per cord could not 

 be ascertained. 



From these figiares and the analyses, the amounts of potash and 

 phosphoric acid recoverable in the ashes of a coi'd of oak and of 

 hickory are f ovind to be as follows : 



Oak. Hickory. 



Potash, 2.3 4.3 lbs. 



Phosphoric acid, - — -5 1-3
