85 A 18 d 8 Manufactured Goods. The German Statistical Department publishes annually particulars relating to the rubber tyre industry only.

Two other countries—France and Italy—manufacture rubber goods to a value comparable with those manufactured in the United Kingdom, Canada or Germany and Belgian production is comparable with that of Australia and Japan, But these countries do not publish any details of production. As far as we have been able to ascertain, no details of production are published in the other producing countries. In the table given above, the output of the United Kingdom includes not only the production of the rubber industry proper, but also the value of rubber-proofed garments made in the clothing industry and of games and toys made in the sports and toy trades. The production of the United States and Canada excludes these items. No further information regarding the output of Australia and Japan is available. STATISTICS OF IMPORT AND EXPORT TRADE. The returns of imports provide little comparable data. The countries which import rubber manufactures are much more numerous than those that export them, and the imports of particular classes of rubber manu- factures are, in many cases, so insignificant that they are not given separate headings in the import returns. As the chief exporting countries are few, the export returns of these countries furnish the data for a statistical survey of the international trade in rubber manufactured goods. Even in the export returns of these few countries, there are so many significant differences of classification that a complete comparison of the trade of the various countries is not possible. Although there are differences in classification between the export returns of the United Kingdom, Canada, the United States and Germany, it is possible to make, in many instances, reliable comparisons. The classification of rubber manufactured goods adopted by France and Italy render impossible any detailed comparisons between their trade and that of the other principal exporting countries.
