 Government is making great efforts to encourage the 

 establishment of Hevea plantations. 



Wright gives the following estimate of the world's 

 planted acreage in 1912:

 Acreage under Rubber in different countries. 



Country Acres 



Malaya 420,000 



Ceylon 238,000 

 Dutch East Indies, Borneo and Pacific Islands 240,000 



South India and Burma 42,000 



German Colonies 45,000 



Mexico, Brazil, Africa and W. Indies 100,000 



This estimate is probably rather under than over the 

 mark. An estimate by Van den Kerckhove gives 220,000 

 for Mexico, 80,000 for Brazil, and 100,000 for Africa. 

 His total for the world is 1,131,000 acres in 1912. 



Production from Estates. 



A large proportion of the acreage described above 

 has been planted since 1906, and it will be readily 

 understood that the production of plantation rubber is 

 rapidly increasing, and is likely to increase at a still 

 more rapid rate in the immediate future. Indeed, at 

 the present time the increase is in geometrical pro- 

 gression, and for some years past the output of rubber
