BUD VARIATION IN THE EUREKA LEMON.

again assorted and classified according to their condition and appear- 

 ance. These studies were made for the ])urpose 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 

 used for this illustration. 



RECORDING THE DATA. 



The data obtained from the study of the fruits jDicked 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 showmg the 

 total production for the year, together with accompanying observa- 

 tions, were transferred to a form providing for the brmging 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.
