pass through the meshes of the muslin in the Macadam strainer 

 but in the latter all substances of higher specific gravity than 

 caoutchouc or water are eliminated. For the removal of scraps of 

 bark Mr. BAMBER'S machine is not so suitable as the weight of 

 these particles is not sufficient relative to the caoutchouc and water 

 to throw them out. The fact that in the London market a slight 

 grittiness to the feel in rubber showing the presence of minute 

 grains of sand is considered to lower its value points to the gain of 

 using a machine that will eliminate these small particles which may 

 pass" through the sieve. 



The classes for coagulating methods both mechanical and 

 chemical produced very few entries. 



The class for machines for rolling and washing, with rollers 

 prepared either for crepe or sheet, did not contain any novelties 

 chiefly because no rubber machinery manufacturers from Europe or 

 America sent exhibits. 



The Michie-Golledge machine awarded the gold medal, is a 

 revolving drum within which centrifugal and centipetal forces are 

 exerted to quickly induce coagulation was seen daily working in 

 the show yard and performed its functions very efficiently and 

 expeditiously. 



Latex poured into this machine was in less than five minutes 

 coagulated and removed in large masses ready for treatment in the 

 washers and rollers. 



A prize was awarded to Mr. W. J. BlRD, Duckwari Estate, for 

 a method of inducing coagulation by means of Cream of Tartar 

 (Tartaric acid). The results from the use of this reagent are 

 excellent and it seems to be more efficient than the acetic acid 

 which is generally used. 



A screw press for preparing block rubber had been put up by 

 Messrs. Brown Davidson & Co. and crepe rubber was treated in 

 this with very successful results. The block was pronounced by the 

 rubber judges to be of the highest quality. This press was the 

 only blocking machine shown and received a medal. 



The attendance at the Show and the interest taken both in the 

 Exhibitions and in the lectures and discussions which took place 

 almost every day, was excellent in regard to as Ceylon residents 

 but the number of planters and others attending from other rubber
