In some of the figures above, including those for France, Italy, 
Canada and Japan small quantities of Gutta-Percha, Balata, etc., 
are included. These are probably between 2,000 and 3,000 tons. 
Some 96 per cent. of the crude rubber produced is absorbed by the 
industries of 10 countries. Tt is with the industries in these 10 
countries— with the exception of Russia for which no recent in- 
formation has been obtained—that we shall deal in this survey. 
The predominant position of the United States which alone absorbs 
about 60 per cent. of the production of crude rubber stands out 
clearly.

VI—USE OF RUBBER IN DIFFERENT BRANCHES 
OF THE INDUSTRY. 
19. Crude rubber is absorbed in the various branches of the 
industry in very different proportions in different countries. 
Figures based on manufacturers’ returns are available only for the 
United States. It is estimated that about 75 per cent. of the raw 
rubber absorbed in the United Kingdom industry is used in the 
manufacture of tyres. The remainder is about equally divided 
between mechanicals (belting, hose, packing, etec.); waterproof 
garments and rubber footwear; sports, surgical and hard rubber 
goods; and the requirements of other industries such as the insula- 
fion of wires and cables in the electrical industry, and elastic for 
she textile industry. 
20. The following table, published by the Rubber Association 
of America shows how the rubber used in the United States is 
distributed. The figures represent over 90 per cent. of the rubber 
indugtry of the United States.
