Notes on Above. 
Owing to changes of supervision the conditions were not strictly 
adhered to, and therefore the results of the experiment are rather 
misleading. Special attention is now being given to them. 
RUBBER SEEDS. 
Six hundred thousand rubber seeds were sent to Trinidad. Two 
hundred thousand rubber seeds were sent to Mr B. O Stoney 
Labuan Requests were receieved from Trinidad and Java 
1,000,000 and 100,000 rubber seeds, respectively; 482,000 and 91.000 
have been forwarded. The order .will be completed early in 1911.

Notes on Above. 
Although plot No. 2 has not done well, the results tend to show 
that the higher the elevation the slower the growth of the tree. 
The trees at an elevation of 2,400 feet look as healthy as those 
at 300 feet.
