bathroom to refresh him, instead of a wooden hut, hastily built 
and full of leaks. The Superintendents’ bungalows on most estates 
give the impression that the rubber industry is in a parlous state, 
instead of one of the most, if not the most, profitable industry 
in tropical agriculture. 
The lines, as a general rule, are relatively* more comfortable 
than the Superintendents’ houses. Most of them are raised some 
5 or 6 feet from the ground, and as the space underneath is used 
by the coolies for their cooking operations the whole of the rooms 
are constantly fumigated or insects driven away. 
An interesting and instructive article on coolie sanitation and 
the methods to be adopted in various coolie diseases to which is 
appended plans for lines has been prepared by Dr. Gerrard for 
the “Agricultural Bulletin.” It will be useful to plantersin Malaya 
as a handbook to the medical treatment of estate coolies.

Yield of Dry Rubber Per Tree. 
The average amount of dry rubber extracted per tree, calcu- 
lated by the figures in the tables gives 1 lb. 12 oz. per tree. Many 
of the trees in the Federated Malay States are 10 years old, and 
some over 20 give a good deal’more than 2 lbs. a tree, but even 
taking this into consideration this average is a high one, and if it 
is maintained means a very large margin of profit over expenses 
of production. 
Federated Malay States Rubber Progress. 
At the end of 1905 there were in the Federated Malay States 
alone about 40,000 acres planted with rubber. At the close of 
1906 more than 85,000 acres. Between 6,000,000 and 7,000,000 
trees at the beginning of last year, and on the 1st January this 
year over 10,000,000. The output of dry rubber was about 130 
tons in 1905 and in 1906 385 tons, three times as much. The 
reason, that while the acreage has more than doubled the number
