BUD VARIATION IN" THE MARSH GRAPEFRUIT. 
11 
ance-record work the fruits are first assorted into the usual com- 
mercial sizes, viz, 112 and smaller, 96, 80, 64, 48, 32, and 24 and 
larger, indicating the number of fruits per packed box. This work 
is done by the aid of rings, so that the assortment will be uniform 
for all trees. In commercial practice the sizing is largely done with- 
out the use of rings. After the fruits have been assorted according 
to size, each lot is assorted according to grade. 
RECORDING. 
The fruits of each grade of each size are counted and weighed, and 
the results entered on the performance-record blank, as shown in 
Table I, embodying the data from a productive tree of the Marsh 
strain of Marsh grapefruit in investigational plat A of the Dixon 
•grove (planted in 1898), grown by L. V. W. Brown at Highgrove, 
Cal. At the time of entering the record one fruit of each grade of 
three sizes, viz, large, medium, and small, is laid aside for examina- 
tion as to the number and characteristics of the seeds. Any variable 
or other unusual fruits are also taken out at this time for further 
detailed study and classification. The detailed performance record 
of each tree is copied from the field form on an annual form similar 
to that shown in the upper part of Tables I and II, and the summary 
record from the annual form is in turn entered on a period form, as 
shown in the lower part of Tables I and II. 
Table I. — Performance record of Marsh grapefruit tree No. 1-14-30, Productive Marsh 
strain. 1 showing the weight and number of fruits of each size and grade, seeds counted, 
and sports noted in detail for the season of 1912 and summarized for the 6-year period, 
1910 to 1915, inclusive. 
[The summarized 6-year record illustrates the method of assembling the data of successive seasons for 
careful comparison and study. In practice, the variable fruits produced by the tree each season are 
listed on the back of the form. The weights are given in pounds and ounces, except that the 6-year 
totals and the averages are expressed decimally in pounds. This tree is listed in rank 1 of Table III.]
