for rubber cultivation as places already planted ; new roads and 
branch railways will greatly assist in the opening up these new 
districts. 
While large areas have been planted in rubber, still larger 
areas, amounting at the end of 1906 to some 200,000 acres, have 
been applied for and granted for this cultivation. The State of 
Perak has gone ahead more rapidly than Selangor in rubber 
planting, and in Lower Perak an entirely new rubber district, in 
which rubber is growing with quite as good results as in the 
more popular rubber-growing districts; has been opened and 
planted. This district, S’tiawan, is at present very inaccessible 
but a connecting road has been begun. 
The fact that the Ivlang district, where rubber was first 
planted, has now been all taken up for rubber and no more remains 
unalienated, has forced would-be rubber planters to go further 
afield, with the result that in Selangor, Perak and Negri Sembilan 
fine clearings have been made in new districts. 
Protective Forest Belts. 
The value of protective forest belts was explained in the last 
report and these necessary guards against plant diseases are still 
occupying my attention, and Government will be asked to 
continue the policy and reserve more of these belts to cut off 
various planting districts from each other. Dr. Treub, of Java, 
who is the greatest living authority on tropical agriculture, is 
much interested in these protective jungle belts, which, he 
considers, a sound and wise provision which unfortunately in Java 
and other agricultural countries it is now too late today out as too 
much land has already passed away front the control of the 
State. 
Camphor. 
Experiments have been made with the propagation of 
camphor by means of cuttings. The first trial of some thousands 
of these was not successful owing to lack of supervision, but 
more have been struck and itds hoped to be able to produce a 
stock of young plants. 
As the camphor plant does not fruit until it is some 30 or 40 
years old it is important to learn how it can be propagated by 
cuttings. More seed will be obtained from Japan where the only 
seed trees are known, and plants from these seeds when estab- 
lished w ill be available for planters who wish to give this plant 
a trial. 
While not recommending that the cultivation of camphor 
should be taken up over large areas it must be remembered that 
the price of camphor is exceedingly high and the prospects of high
