HOLLAND'S RUBBER COMMERCE, 1917-1919 



A comparison of the values of imports of rubber and gutta 



percha and rubber manufactures into the Netherlands for the 



past three years is given in the following table: 



Articles 1917 1918 191!/ 



Rubber and gutta perclia $7,200 $3,600 $6,181,600 



Rubber manufactures _'5.60O 7,600 5,675,200 



Exports of rubber and gutta percha in those three years totalled 

 $56,800 in 1917, $50,400 in 1918, and $3,961,600 in 1919. The 

 great volume of trade in 1919 represented trade conditions in 

 the country itself and conditions in territories which had to draw 

 upon it for supplies during the year. A large proportion of the 

 imports into the Netherlands are goods that pass into the interior 

 of Europe and a large share of its exports are goods manufac- 

 tured in central Europe and sent abroad by way of the Nether- 

 lands. While previous to the war the greater part of this transit 

 trade went through the country without breaking bulk, the greater 

 portion of this trade now represents goods bought by Dutch 

 importers and exporters and is fairly and directly trade of the 

 country. What was once meie transit trade became actual Dutch 

 trade in 1919. Exports of rubber from the Netherlands to the 

 United States in 1919 were valued at $3,135,949. Declared ex- 

 ports from Rotterdam included 3,015,938 pounds of crude rub- 

 ber, valued $2,622,860. 



Rubber and gutta percha manufactures to the value of 

 $218,860 were imported into the port of Dairen, Manchuria, during 

 1919, to be forwarded by rail to the interior. Similar imports in 

 1918 were valued at $67,255.
