BUD VARIATION IN THE EUREKA LEMON. 
29 
the complete records of all of the trees in this bulletin; hence, it has 
been necessary to select a number of trees for this purpose. Tables 
VIII and X give the detailed performance records of 24 representa- 
tive lemon trees of the 117 in the investigational plat of the Eureka 
variety. This list includes examples of all the strains found in the 
plat and was made by arbitrarily selecting every eighth tree of the 
Eureka strain as listed in Table VI, every fifth tree of the Shade-Tree 
strain, every fourth tree of the Small-Open and Dense-Unproductive 
strains, and both trees of the Dense-Productive and Pear-Shape 
strains. In each case the highest and lowest ranking trees of each 
strain are included. This basis was adopted in order to remove all 
chance of any personal bias in the selection of the trees and is thought 
to include more representative trees than the basis employed for this 
purpose in earlier bulletins of this series. Tables VIII and X are 
thus made to include 10 trees of the Eureka strain, 4 of the Shade-Tree 
strain, 3 each of the Small-Open and Dense-Unproductive strains, 
and 2 each of the Dense-Productive and Pear-Shape strains. 
Table VII.—: Distribution of lemon trees of the Eureka variety in the investigational per- 
formance-record plat, showing also the strain and the rank in crop production of each 
individual tree for the 6-year period from July, 1911, to June, 1917, inclusive, 
[The positions of the trees in ranks 67, 69, 90, 96, 97, 101, 106, 107, 109, 115, 116, and 117 are not here indicated. 
As shown by their location numbers in Table VI, they were situated at varying distances outside the 
main body of the plat, and it was thought inadvisable to include them in this table. This orchard is 
planted on the contour and on that account the trees in rows across it do not bear the same number, 
counting from the southern end, which is taken as the head of the row. The trees in rows 74 and 75 are 
numbered one in advance of the nearest one in row 73, and those in rows 76 and 77 are two in advance of 
those in row 73, as indicated. Explanation of symbols: 0= Eureka strain, A= Shade-Tree strain, 0= 
Dense-Productive strain, □= Dense -Unproductive strain, ®= Pear-Shape strain, ^= Small-Open 
strain, x = not included in the record.]
