 and, size produced, summarized for a period of five seasons, 1911 to 1915, inclusive. 



[This table shows a steady increase in production. The weights are given in pounds and ounces, except 

 that the 5-year totals and the averages are expressed decimally in pounds. This tree is listed in rank 3 in

i 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 and 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, 

 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
