1 The large number of culls occurring in 1913 were caused by the severe freeze oi that season. 
The seasonal variation in production within a strain is illustrated 
in Tables X, XI, and XII. Table X shows the period performance 
record for five seasons of the tree of the Productive Washington strain 
which is listed in rank 3 in Tables IV arid V. This record shows a 
regular increase in production from year to year, a condition which 
is most desirable from the standpoint of profitable orange growing. 
Table XI shows the period performance record for five seasons of the 
tree of the Productive Washington strain which is listed in rank 262 
in Tables IV and V. This record is comparable with that in Table X 7 
but shows a gradual decrease in production, a condition which is 
undesirable. Table XII shows the period performance record of 
the tree of the Productive Washington strain which is listed in 
rank 50 in Table II and in rank 87 in Table IV. This record 
illustrates the alternate-bearing habit of many of the trees under 
observation. A heavy crop is followed by a lighter one the next sea- 
son, but the production gradually increases during a period of several
