The increasing importation of Canada ashes into various parts of 

 the state, 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 on a fair percentage of potash, but also on the pres- 

 ence of more or less of all the various mineral elements essential to 

 the (jroioth of plants. 



Wood ashes, like barnyard manure, on account of their compound 

 character, meet to some extent at least, not only known, but un- 

 known deficiencies in valuable soil constituents. The thorough 

 mixture of their various constituents has no doubt a beneficial infiu- 

 euce on their action.

 The ash of the tobacco plant, like that of other industrial crops, 

 usually varies less in regard to absolute quantity, than to the relative 

 proportion of its essential elementary constituents. Potash is 

 known to vary as high as fifty per cent, in consequence of modes of 

 cultivation and variety of soil, independent of the variety of plant.
