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 affect 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.
