Considering the increased prices and demands during these last 

 few years, which would naturally produce a larger supply if it was to 

 be bad, 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 1 903. In fact, it is clear that 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. 



RUBBER EXPERIMENTS IN THE BOTANIC 

 GARDENS, SINGAPORE. 



We give in this number the continuation of the experiments on 

 Para rubber trees in the Botanic Gardens, carried out last year and 

 part of this one. This series of returns and calculations constitutes 

 the result of Experiment V. The next Number of the Bulletin will 

 contain the results of Experiment VI, the last of this series, and will
