In choosing ])otwcon loinoii trees which wore uhke in all oilier re- 

 pects, that one would be considered the most desiraljlc which pro- 

 duced the largest quantity of fruit of the Green grade during May, June, 

 July, and August. The summer heat causes a considerably increased 

 consumption of lemons, resulting normally in a higher price being paid 

 for them, especially in the late summer when the supply is greatly re- 

 duced. Hence it will be understood that, other things being equal,

Fig. 13.— Percentages of the total yields of fruits of the Green and the Tree-Ripe grades, by weight, pro- 

 duced each month by the trees of the various strains of Eureka lemons in the investigational performance- 

 record plat during the 3-year period from July, 1914, to June, 1917, inclusive. The data here presented 

 are the same as those presented in figure 12, being here rearranged to show more clearly the variations 

 between the diHerent strains each month. The strains are listed from left to right in the same order as in 

 figure 12. Arrangement of strains: /, Ten highest producing trees; g, 76 trees of the Eureka strain; 

 S, 2 trees of the Dense-Productive strain; J^, 117 trees, entire plat; 5, 10 trees of the Small-Open strain; 

 e, 2 trees of the Pear-Shape strain; 7, 17 trees of the Shade-Tree strain; S, ,10 trees of the Dense- 

 Unproductive strain; fl, 10 lowest producing trees. 



the most valuable variety or strain for the grower wnll be that one 

 which produces the larger proportion of its fruit in the late spring and 

 summer. Such fruit can be shipped immediately after it has been 

 cured, and under normal conditions it will bring satisfactory prices. 

 Fruit of the Green grade is normally picked only when it has reached 

 a certain diameter. In practice this size sometimes varies at differ- 

 ent seasons or on account of changed market requirements, and in
