MET attention has been py in the Kew Bulletin to more 
than one direction in which it may be hoped to enlarge our 
Mi ue of india-rubber, and correspondents of ihis establishment, 
at home and abroad, have suggested improved methods of tapping 
the trees and coagulating the milk, so as to produce the best 
qualities of commercial rubber.

of the interior in the parishes of Sireen and St. Elizabeth. 
It is closely allied to the Demerara rubber plant already men- 
tioned, but the caoutchouc, judging by the results of experiments 
made by the India-rubber and Gutta-percha Company of Silver- 
town, appears to lend itself more readily to the requirement of
