The comparatively small quantity of rubber exported 

 up to the present has gone principally to Rotterdam or

 at the regular rubber auctions, and there are indications 

 that such shipments may increase in the future. Prices 

 in Java are governed by London and Liverpool quota- 

 tions, local sales allowing a deduction equivalent to the 

 value of freight, insurance and commissions.
