BUD VARIATION IN THE EUREKA LEMON. 
69 
Table XIII. — Average yields and percentages of total yield of fruit of the Green and 
Tree-Ripe grades picked each month from the lemon trees of the various strains of the 
Eureka variety in the investigational performance-record plat during the 3-year period 
from July, 1914, to June,. 1917, inclusive. 
[The strains are listed in the order of their total-production rank for six years, as shown in Table X.]

1 The season percentage is calculated on the production for the four months, May to August, inclusive . 
In Table XIII and in figures 12, 13, and 14 are shown some of the 
recorded differences in season of production of fruits of the Green and 
Tree-Ripe grades by the Eureka lemon trees of the various strains. 
On account of the interruption to regular picking which resulted from 
the freeze in January, 1913, only the three years from July, 1914,
