Fig. 3.—Diagram showing the average annual totalcrop of Lisbon lemonsand the production by the three 
commercial grades from the individual trees in the investigational performance-record plat during the 
4-year period from July, 1913, to June, 1917, inclusive. The data for 14 trees, as noted in Table I, cover 
only the 3-year period from July, 1914, to June, 1917, inclusive. 
Table II shows the relative positions of the individual trees in the 
Lisbon investigational plat. The strain to which each tree belongs 
is indicated and its rank by production as listed in Table I. This 
illustrates the distribution in the plat of the trees of the different 
ranks and strains.
