viii PREFACE 



There is a strong probability in favour of the view that 

 when plantation rubber can be profitably sold at less 

 than two shillings a pound, the plantation industry will be 

 able to compete successfully Avith all kinds of forest rubber 

 and will have little to fear from the competition of the 

 synthetic material.
