time during the year were the trees under observation without 

 both flower and fruit. On the other hand, there are times when 

 growth is more rapid, more flowers are developed and the ter- 

 minal nodes elongate much more rapidly. The exact time of these 

 periods has not yet been determined definitely, but data are being 

 collected. 



" The habit of the plant is being closely studied to determine 

 the characteristics of each change and at what point in this growth 

 the tips must be removed to produce the changes under discus- 

 sion. It is possible that the power to produce pistillate flowers 

 is inherent in the plant, being dormant unless some shock is given 

 to destroy the equilibrium of the growth forces. This inherent 

 quality is indicated by the fact that in some countries the plants 

 are sometimes found naturally monoecious."
