THE CEYLON RUBBER EXHIBITION- 



List of Prizes and How to win Them. 

 (Reprinted from the "Ceylon Observer" June 19.) 



We published last week a series of special 

 article on the Prize List of the Ceylon Rubber 

 Exhibition, giving explanations and comments 

 on the various subjects for which prizes are 

 offered. These will no doubt prove useful to 

 planters. Most planters in Ceylon, the Straits 

 and India have now obtained a copy of our second 

 edition of Mr Herbert Wright's "Hevea hrasilien- 

 sis." In order to help exhibitors at the forth- 

 coming exhibition we have drawn up a list 

 of most of the prizes and the reference pages 

 where information of value of the subject is 

 given in the edition just published. Those 

 planters who have not obtained copies should 

 do so at once and read up the portions indi- 

 cated opposite the classes in which they wish 

 to enter exhibits.
