Ihis return clearly shews that morning are better than evening 
tappings, that trees can be tapped twice within the period of a year 
but the interval of rest should not be less than five months, that 
the dormant months December, January and February yield a 
smaller percentage of caoutchouc, and that the best season for 
tapping is from April to November. Turning to methods of tap- 
ping we have not found any advantage in respect of yield by the 
spiral over the herring-bone and considering the small advantage 
of the double over the single incisions we think the single cut with 
small trees would best economise the bark. 
Wound Recovery. 
In the case of a tree which had never been tapped, or in which an 
interval of several years had elapsed between the different tappings, 
the yield of rubber would, we have reason to believe, be the maxi- 
mum in whatever month or season the tree was tapped but sub- 
sequent tappings would be modified by the interval of rest and by the 
physiological phase of the tree at the time of tapping.
