Fig. 5.— Diagram showing the percentage of variable frrits of the Lisbon lemon occurring on the trees of 

 the different strains in the investigational performance-record plat during the 4-year period from July, 

 1913, to June, 1917, inclusive. The data for the trees of the Bull strain and three other trees, as indicated 

 in Table I, cover only three years. The proportions are based on the number of fruits produced. 



Table VII. — Production of fruit of the three different grades and of variable fruits picked 

 from the lemon trees of the several strains of the Lisbon variety in the investigational per- 

 formance-record plat during the 4-year period from July, 1913, to June, 1917, inclusive. 



[The strains are ranked according to their proportion (by weight) of fruit of the Green grade.]
