It is of interest to note that the amount of moisture in proportion to the 
dry weight of the Elberta fruit buds is greater than that of the Greensboro 
buds in almost every case. There are, however, a few exceptions. On 
November 8, the Greensboro values were greater for two of the trees on 
high ground and for one tree on low ground. The Greensboro values are 
also greater on December 6 and again on March 7 for this same tree growing 
on low ground. There are three cases in which the values of the Greensboro 
equal those of the Elberta: one on November 8 for a tree on low ground, one 
on December 6 for a tree on high ground, and one on January 7 for the 
same tree on high ground. There is no uniformity in the differences be- 
tween trees receiving fertilizer treatments. Some differences are seen, but 
these are probably due to individual variations. No great differences are 
apparent between the ratio values of buds taken from trees growing on 
high ground and from those growing on low ground. 
Conclusions 
Attention is called to two points in these observations. First, there is a 
marked seasonal increase in the water content of fruit buds of the Elberta 
and Greensboro peach whether determinations from individual trees or from 
averages are considered. Second, as the season advances the difference
