Review of the Crude Rubber Market 462 



THE ALL-CEYLON EXHIBITION AT COLOMBO. 



It is expected that rubber will be represented on a very com- 

 plete and unusually large scale at the "All-Ceylon Exhibition" to 

 be held at Colombo from July 1 to July 6 next. No less than 17 

 classes will be devoted to rubber, and to the machinery, tools, etc., 

 connected with that industry. The exhibition will as far as pos- 

 sible be divided into districts, and a number of valuable prizes 

 will be offered.

INCREASED RUBBER IMPORTS. 



As illustrating the e.xpansion of the American rubber in- 

 dustry, it is of interest to note that the official statistics for the 

 nine months ending March 31 last, of United States imports of 

 india-rubber, show a quantity of 80,730,111 pounds as com- 

 pared with 54,029,940 pounds for the corresponding period a 

 year earlier. These figures are for india-rubber alone, apart from 

 balata, guayule, gutta jelutong and gutta percha. The statement 

 in a daily journal that the imports of crude rubber for the ten 

 months ending .April 30, 1912, were 425,000,000 pounds, as com- 

 pared with 303,000,000 pounds in 1911, is an obvious mistake.
