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.

 fruits of Orchard grade and of variable fruits borne by each tree, 1912 to 19 15, inclusive.

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
