Samples 1, 2, 3, 4, 5, 6 represent the average quality of 

 Canada wood ashes sold in our section of the Connecticut 

 valley, at from 33 to 35 cents per bushel. Sample 7 was 

 of an exceptional light color, and contained a larger per 

 cent, of lime, yet compared well otherwise in composition 

 with the others. The increasing importation of Canada 

 ashes into various parts of the States renders it advisable to 

 insist hereafter upon guaranteed analyses as the basis of 

 commercial transactions. 



The universal high opinion of wood ashes as a fertilizer 

 does not depend merely upon a fair percentage of potash, 

 but also on the presence of more or less of all the various 

 mineral elements essential to the growth of plants.
