NOTES ON DAMAR TAPPING PENAK. 
(BALANOCARPUS MAXIMUS.) 
The “ damar ” of commerce, known to the trade as Damar Mata 
Kuching, is obtained principally from the Penak tree, and is col- 
lected by cutting through the bark down to the cambium. The damar 
begins to exude in about two days and is ready for collection in 
from seven to fifteen days; some varieties of Penak give quicker and 
better returns than others. The collector chips off the damar, which 
has enuded, with his parang into a receptacle made from the (< Palas” 
leaf, and then reopens the cuts, by cutting off a thin layer of bark. 
Trees can be tapped without detriment once a fortnight, but 
more frequent tapping is apt to cause premature decay of the tree, 
especially if the cuts penetrate the heartwood rendering the tree 
liable to attacks of fungus: also the tree should not be “ringed” 
completely. 
The damar exudes more freely in the dry weather. 
After collection the damar is picked over by women, and gener- 
ally placed on the market in two qualities. 
The trade is at present in the hands of a few Chinese, who keep 
prices down ; but there is little doubt but that a very much better 
price could be obtained by direct shipment to Europe. 
A few of the more venturesome climb the trees to collect the 
damar, from the branches, where it sometimes collects in large Jumps 
having exuded naturally due to some injury to the tree; but this is 
a work of great danger and several fatalities have occurred. 
As much as twenty-five catties can be obtained at one tapping; 
from three hundred cuts, 6 " apart, if the tree is climbed, and damar 
collected from the branches ; but the average yield of a tree is about 
one catty per month. A good collector can get a.s much as five 
catties a day, which he can dispose of to the Chinese dealers, at 
prices varying from four to eight cents a catty according to quality.
