RUBBER IN JAVA. 
The Consular Report for 1909 gives the following : “The Rubber 
production of Java is still inconsiderable, and will remain so for some 
years to come. A great deal of clearing and planting of new ground 
has been done during the past 12 months and the demand for land 
suitable for rubber cultivation has been very strong. Numerous 
estates which have not proved successful under coffee have been dis- 
posed of and in cases where rubber had been planted for a year or 
two the prices paid were very high. No figures are so far procurable 
showing the acreage under rubber in Netherlands Indies, but an 
attempt has been made to ascertain the amount of capital sunk in 
rubber estates in Java, Sumatra and Dutch Borneo at the end of 1909, 
with the following result : — 
British 
Dutch 
Franco-Belgian 
German 
£2,500,000 
1,500,000 
145,000 
18,500 
Total £4,163.500 
These figures are, however, merely approximate.

“1 had always supposed that the one danger which .would 
probably attend rubber growing in Fiji would be the breaking of 
these somewhat brittle trees by hurricane winds. I am glad- therefore 
to. report that our young rubber trees suffered very little .on the
