BULLETIN 624, U. S. DEPARTMENT OF AGRICULTURE. 
than in 1913. The 1915 records of many of the trees show this same 
tendency in a lesser degree, indicated by a relative decrease in pro- 
duction of fruits of the very smallest sizes, even where, as was the 
case with the tree listed in rank 3, the total crop for that year was 
larger than during the previous year. 
Table II shows the percentage of fruit of the first or Orchard grade 
produced by each tree and the proportion of variable fruits recorded 
from each during the 4-year period. These percentages are calcu- 
lated from the records of actual yields shown in Table I, and they are 
an aid in interpreting those data and in judging the relative commer- 
cial value of the individual trees both from the standpoint of crop 
production and as sources of desirable bud wood.

Table III shows in its first section (sec. A) the performance record 
of an orange tree of the Valencia strain for the season of 1915, as 
entered on the annual record form, and also the 4-year period 
performance record of the same tree. The detailed annual record 
is copied from the field notebook and shows the data therein 
recorded for each individual tree. The summary of this annual 
record is copied on the period form, as shown by the second
