These pages are not intended as a study of the culti- 

 vation of Hevea in the Straits Settlements in general, 

 but only as a manual for the planter. Long series of 

 statistics, observations at length on problems such as 

 green manuring and catch crops are avoided ; for the 

 latter the special literature on the subjects should be 

 consulted; for the former, the Handbook of HERBERT 

 WRIGHT. 



In view of the rapid pace at which Hevea planting is 

 proceeding in the tropics, it is to be expected that impro- 

 vements will continually be effected in its cultivation, 

 cropping and preparation. I hope therefore that planters 

 who may discover new methods will communicate with 

 me from time to time, so that I may avail myself of 

 useful hints in the writing of a second edition of this 

 work. I shall always be happy to enter into personal 

 correspondence with planters.
