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.
