gives the impression of being of an even composition, 
but which is not very coherent or elastic. When 
mixed only with getah dujan, which is itself a good 
kind of getah, a good product is sometimes obtained 
which is fairly coherent, but which by its brittleness 
shows that it is mixed with dujan.” 
The largest quantity of gutta received is said to 
be hangkang ( Palaquium leiocarpum Burck) which 
is exported to the amount of several thousands of 
tons per year from Borneo. It has a smell similar 
to that of Jelutong. “ Among the gutta perchas 
hangkang occupies about the same place as Jelutong 
among the rubbers ; its market value is higher, 
because hangkang does not contain an excessive 
amount of water like the jelutong which is offered 
for sale.” 
Jelutong seems also to be very largely used. 
As will be seen from the table above, the 
quantity of gutta percha exported from Singapore 
is almost 80 per cent, greater than the amount 
imported and there is a certain decrease in the 
amount of gutta inferior during its stay in Singa- 
pore. The unit value of the gutta is decreased and 
the unit value of the gutta inferior is slightly 
increased by the treatment given to it in Singapore, 
but the nett result to the trade in Singapore amounts 
to a profit of more than $2,000,000 per year. 
Practically the only unadulterated gutta percha 
known to be exported from Singapore is the leaf 
gutta from the different factories and the tapped 
gutta supplied by the Forest Department of the 
Federated Malay States.
