This tapping commenced on September 16th and was carried 

 on until September 29th, each tree having been tapped eleven 

 times, and I would observe that 7 or 8 more tappings might have 

 been made without removing an extravagant amount of bark. I 

 conclude from the result obtained that, only one side of each inci- 

 sion need be tapped, and that the lower side is preferable. As will 

 be seen, the result of tapping the lower cuts is better than the 

 upper ones, and nearly as good as tapping both, while the addi- 

 tional work is equal to tapping another tree, as much more careful 

 work is necessary with the upper cuts to prevent the latex from 

 overflowing and splashing outside the channel. 



From these trees I do not suppose that any more, or very little, 

 rubber was obtained by three sets of tappings than would have 

 been obtained from one set, as will be seen from the following 

 result obtained from another tree which is 14 years old and has a 

 o-irth of 5' oj" at 3 feet from the ground. This was tapped in the 



usual way — a centre channel 4

Dry Rubber 325 



About 2 lbs. of dry rubber in 8 tappings and the latex running 

 freely and increasing daily when the tappings had to be aban- 

 doned as more time could not be spared. It will be noted, and 

 I am of opinion that, the latt^x exudes better when the trees are 

 tapped daily than at intervals, but a few clays should elapse after 

 first opening an incision before daily tappings commence.
