it has a faintly yellow colour, has a value of $50 
to $60 per pikul, and makes up 48 per cent, of the 
total: amber , which has a slightly darker tint, 
apparently due to being a little older, has a value 
of $35 to $45 per pikul and makes up about 15 per 
cent, of the total. The residue is made up of 
“ dust.” This makes up approximately 14 per cent, 
of the total and has a value of only $6 to $10 per 
pikul: So far as has been discovered the dust is 
chemically of the same quality as the larger pieces, 
but it is harder to get it free from impurities, such 
as fragments of bark, insect remains, etc. The 
dust is classified as coarse or fine, according to the 
size of the particles. Considerable improvements 
have been made in the cleaning of the damar by the 
use of washing devices, careful hand sorting, etc. 
Experiments made by the Agricultural Chemist 
F.M.S. & S.S. have shown that there is no appreci- 
able difference chemically between the grade known 
as “ pale ” and that called “ amber,” nor for the 
matter of that between the “ pale ” and the dust. 
The darker grades do, however, produce slightly 
darker coloured solutions. The analyses referred to 
have given the following results: — 
Samples pale to amber in colour. 
Melting point 90° to 92 °C. 
Ash 0.015 to 0.33%. 
Acid value 38.9 to 45.4. 
Solubility. 
Alcohol — partially soluble, opalescent solution. 
Ether- 
Petroleum ether — partially soluble, slight opale- 
scent solution. 
Turpentine — soluble, clear solution.
