It will be seen that the gain in value shown for 
the Singapore traders average's about one half million 
dollars per year on the two products, or about 22 
per cent, on the value of the business handled. 
Unfortunately, the different kinds of damar do not 
appear separately in the customs returns, so it is 
not possible to tell the proportions of the different 
kinds of damars handled. 
The different damars receive a great deal of 
attention at Singapore and are very carefully sorted. 
A large number of grades are recognized. Pieces 
which are dull or contain impurities are scraped and 
the impurities picked out. The grading is usually 
done by Chinese women. _ It seems probable that 
there is a certain amount of mixing of low grade 
with high grade material to increase its bulk.
