Some indication of the relative effect of the two kinds of 
manures may be gained from knowing the relation by weight 
of roots and tops. In 1900 and 1901 carefully selected beets 
from all the plats were weighed before and after trimming. 
The results of these weighings are given in Table XX. 
It does not appear from the above data that stable manure 
induced an excessive growth of leaves as compared with com- 
mercial manures. 
It is fair to inquire if, in the nature of things, there are 
good reasons for expecting results different from those detailed 
here. Why should plant food derived from stable manure cause 
growth unlike that sustained by chemical manures? While we 
cannot enter into all the secrets of the life of the plant, sucha
