THE DA COSTA PATENT "RAPID" 



SPECIFY 



RUBBER LATEX COAGULATOR 



FOR THE PERFECT COAGULATION OF ALL KINDS OF LATICES 

 BY A SYSTEM OF SMOKING. 



Rubber is now being exported from the Far East, etc., the Latex of which has 

 been completely coagulated by the DA COSTA PATENT "RAPID" SMOKING SYSTEM 

 and prepared by BRIDGE'S IMPROVED AND PATENTED MACHINERY. This is known 

 as the "DA COSTA" SMOKED RUBBER, and is commanding the highest market 

 prices as far as Plantation Rubber is concerned. It must be clearly understood 

 that, by this system, raw manufactured Acetic Acid is not used in any shape or 

 form but, on the other hand, Smoke is injected by Steam directly into the Latex 

 with the result that every molecule is thoroughly coagulated and made antiseptic. 

 The Secret of the Preparation of Rubber lies in the proper coagulation of the 

 Latex. The best Rubber in the World is undoubtedly "Para" (Brazilian Wild 

 Rubber), that is, Hevea brasiliensis from the Amazons. Why? BECAUSE IT IS 

 SMOKED DURING THE PROCESS OF COAGULATION.
