Excepting the years 1901, when the difference of seeds between 

 the two Seasons was the least recorded, and 1904, when there was 

 a moderate crop both in the Spring and Autumn, this analysis tends 

 to prove that, while there are two seasons when flowers and fruits 

 may occur in some years within the period of a year, there is never 

 more than one heavy crop, and that the Autumn is the more uniform 

 crop of the two, as the Spring has only exceeded the Autumn crop 

 twice in ten years; and further that the Autumn fruit periodicity 

 represents the true normal condition of the tree. There is, how- 

 ever, much variation as mentioned of the years 1901 and 1904 to a 

 return of almost nil for the Spring crop of 1905, while the Autumn 

 crop of the same year was the largest recorded. This abnormal 

 variation is undoubtedly due to climatic conditions, as is shown by 

 the comparison of an excessively wet or very dry year. It is very 

 seldom that in the old trees of the Botanic Gardens any are seen to 

 be completely defoliated and how often the reproductive functions 

 of the tree are excited into activity can be judged by the return of 

 the seeds procured at different periods {see page 441). It will be 

 noticed that a month without any seed crop is rare but as might be
