The old opinion that the tree is of very slow 
growth is evidently erroneous, although trees which 
have insufficient light, because of shade from larger 
trees, probably do grow very slowly. It is probable 
that carefully regulated conditions in the forest or 
in a plantation may secure a rate of growth even 
more rapid than that indicated. 
3. Natural Regeneration. 
In places there is very good natural regenera- 
tion, but seedlings are often choked out or very much 
retarded in growth by other trees and brush. Fruit 
is borne very abundantly some years, but little of 
it survives. A tree of medium size may bear from 
5,000 to 10,000 seeds. It is ' said that, in many 
cases, the flowers do not reach maturity because 
they are attacked by insects or because weather 
conditions are unfavourable. A heavy rain at the 
time that the flowers are open may do so much 
damage that no fruit will be set. There seem to 
be a number of chances which may prevent the 
development of fruit. In spite of unfavourable 
conditions, it is doubtful if there is any year when 
there is no seed, although the time for the crop is 
not certain. Ripe fruit have been collected in the 
months of January, February, March, May, June, 
October, and November, and fully opened flowers in 
the months of March, June, July, August, September, 
October, and November. It is doubtful if it can 
be fairly said that there is a definite and regular 
periodicity of flowering and fruiting seasons. This 
condition is not uncommon among our forest trees 
and probably indicates that the occurrence of 
flowering and fruiting times is closely tied up with 
the distribution of the rainfall. This is further
