again assorted and classified according to their condition and appear- 
ance. These studies were made for the purpose of correlating the 
condition of the freshly picked with that of the cured fruits. During 
storage the atmospheric conditions in the curing room were main- 
tained as nearly as possible at 70° F. and at 90 per cent relative 
humidity.

and equipment apparatus were moved out of the shelter temporarily in order to take the photograph

RECORDING THE DATA. 
The data obtained from the study of the fruits picked from each 
tree at each picking were recorded in special field-note forms, as shown 
in Table IV. In addition to these data, other notes concerning the 
individual-tree behavior were made from time to time. As soon as 
possible after each picking the individual-tree data were transferred 
to forms providing for a maximum of twelve pickings, or monthly 
pickings for one year, as shown in Table V. When the complete 
record for an entire year had been obtained, the data showing the 
total production for the year, together with accompanying observa- 
tions, were transferred to a form providing for the bringing together 
of the data on the individual trees for a period of several years, as 
shown in Table VIII. Photographs of interesting trees, fruits, 
flowers, and foliage were frequently taken, in order to fix definitely 
in the records important phases of tree behavior and fruit charac- 
teristics.
