Under normal conditions it would be supposed that the yield of 

 latex would be nearly uniform, but that is to suppose that each tree 

 is in the same physiological phase at the time of tapping, which 

 seldom occurs, and explains the variation of groups of trees already 

 shewn. That it is so with solitary trees, Table IV furnishes a proof. 

 It will be noticed that the seasons of tapping were Jan - Feb ; Sep - 

 Oct; and Nov - Dec. The season of rest and complete defoliation 

 occurred in March - April and would not alfect the seasons of 

 tapping. If the results of three tappings are reduced to 25 tappings 

 each period, the record would then read :— 



1st tapping 

 2nd „ 

 3rd 



which is fairly uniform.
