a very little being produced then. Thence there was a tolerably 
steady increase. On the 13th a hundred trees were tapped with 
two incisions in the morning and afternoon, giving 17 oz. alto- 
gether. The sudden increase from the 13th onwards was undoubt- 
edly due to the rainfall which commenced & that time. It will be 
noticed that 40 trees with five incisions each give as much latex 
as 20 with ten incisions and loo with two, which shows that each 
cut gives approximate! v the same amount, and the return depends 
more on the amount of incisions than on the size of the tree. 
It was noticed that a tree which at one time produced but little 
rubber, after being cut 10 days in succession, suddenly became 
very productive. It is probable that some trees which may contain 
a very fair amount of latex, require a larger period of “calling 
than others. 
Another curious phenomenon was that after the hot and dry 
season when the rains commenced the old wounds which had long 
ceased to flow, suddenly after a violent shower, broke out again 
and produced long tears of rubber.
