The Lanadron Estates and the Singapore and Johore Rubber Co. 
have also been supplied with a No. 3 size of chamber which has 
recently got to work, and is proving an acquisition for the drying 
of gambier. 
Chambers of large size No. 9 are at work in the Cameroon, 
drying cocoa beans with first rate results as to colour, flavour and 
economy of drying. They are also in use for tea in Assam. 
I have troubled you with a long letter, but as the drying of the 
rubber, gambier and other materials must necessarily be rather 
an important matter with a humid climate such as I understand 
you have in the Malay States, I hope the matter may be of 
interest. 
Under separate cover I am sending you printed matter shewing 
some of the various trades and materials for which vacuum drying 
is replacing the drying rooms hot air stoves, etc. 
If there should be any information you would like I will be glad 
to send it to you. 
Mr. Passburg has an experimental station in Berlin where he is 
continually making drying experiments on materials from all parts 
of the world. 
Yours truly, 
JAMES LIVINGSTON,
