To anyone looking forward a little, one of the most interesting 

 exhibits in the show was the vulcanised and coloured rubber 

 exhibited by Mr. M. K. Bamber, Government Chemist in Ceylon. 

 Mr. Bamber acts, not on the coagulated and macerated rubber, but 

 directly on the latex with the necessary re-agents, and then 

 coagulates, giving a perfect intermixture. 



The coagulated rubber can then be worked up into whatever 

 is required in the ordinary way, and finally heated, when it 

 vulcanizes. One of the most promising of his exhibits was the 

 mixture of fibre and rubber. The fibre, cleaned, is soaked in 

 sulphurized rubber milk, coagulated and then dried, and finally 

 subjected to hydraulic pressure and vulcanized the result being 

 blocks suitable for pavement, etc. By this method rubber can also 

 be turned out of any colour desired, and the colour will not wash or 

 crack off— a great advantage for children's toys. One of the most 

 noteworthy features of the Exhibition was a series of daily lectures 

 on the various parts of the rubber industry— cultivation, tapping, 

 shipment to London, vulcanization, catch crops, pests, etc., etc., 

 and these lectures, with the reports of the judges, description of 

 the machinery, and other things, are now being put together into a 

 book which will form a standard treatise,* to be in the hands of 

 everyone interested in rubber.
