Considering the increased prices and demands during these last 
ew years, which would naturally produce a larger supply if it was to 
be had, we may take it that this falling off in jungle rubber is due to 
the extermination of rubber plants in all these, and indeed several 
other countries. Statistics like these ought to be enough to calm the 
minds of those who are scared by the idea of over-production. 
Another article in the same Number gives an account of the con- 
sumption of rubber in America. This has increased in 1904 to 
27,623 tons as against 24,760 in 1903. In fact, it is clear Uat the 
demand is increasing all over the world, and it is important in the 
interests of all, from planter to consumer, that the cultivation should 
spread as far as it can.
