BUD VARIATION IN THE WASHINGTON NAVEL ORANGE.

to the packing house, except such samples as may be needed for 
further study. In view of the fact that during the performance- 
record work each orange must be handled several times, the greatest 
possible care is used in picking and handling in order to avoid as far 
as possible all mechanical injuries. 
Methods for securing commercial individual-tree performance 
records as a part of the regular fruit-picking operation are described 
and illustrated in United States Department of Agriculture Farmers' 
Bulletin No. 794, entitled "Citrus- Fruit Improvement: How to Secure 
and Use Tree-Performance Records."

DESCRIPTIVE NOTES. 
In addition to the performance-record notes, detailed descriptions 
are made of representative trees and fruits of the different strains 
and variations in the orchard. Specially prepared forms are used 
in securing these data, so that all the records obtained will be com- 
parable and arranged in the same sequence for the purpose of intelli- 
gent study. These systematic notes are particularly valuable in 
interpreting the behavior of the individual trees and in obtaining 
information concerning the correlations of production and the 
physical characteristics of the individual trees and fruits.
