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 th.- 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
