DRY MATTER AND MINERAL CONSTITUENTS.

mercial value of a large number of varieties. The analyses presented 

 in Table VI include the determination of nitrogen, phosphoric acid, 

 potash, and lime. 



The standard list of varieties examined for these constituents was 

 selected with a view to continuing the chemical examination of fruit 

 from these same trees for a series of years, thus establishing the 

 normal content of these important elements. Such determinations, 

 together with the crop statistics from the same trees, will give in time 

 most valuable data for the guidance of cultural practice. There is at 

 present little to be gained by deductions which could be made from 

 the work of this one season.
