Bulletins. 
During my stay in Penang, I investigated the cause of the nutmeg disease which 
was so destructive in i860 and which was said to have re-appeared. I found it to be 
due to a small Scolytid beetle, and an account of the disease and others incident to 
the nutmeg and clove trees was published as a bulletin. Two more bulletins dealing 
with the cultivation of spices and with Ramie, Para rubber and diseases of coffee, 
together with an article by Mr. Curtis on the cultivation of pot plants were prepared, 
and are in the hands of the printers.

Camphor. 
During my stay in Selangor, 1 visited the camphor woods of Rawang, and 
obtained specimens of timber, leaves, etc. in order to experiment with them with a 
view of extracting the camphor, which commands an exceedingly high price. The 
material I brought being insufficient, the Resident sent down a beam of the 
wood on which experiments are still being made at the Laboratory of the Govern- 
ment Analyst. The. camphor oil, Borneo!, is easily extracted by distillation, but the 
solid camphor resists, at present, any methods of extraction.
