lines, as insulated wire, hard rubber, mechanical rubber goods, rubber 
boots and shoes, druggists’ and surgical goods, comprise industries in¬ 
dividual in themselves, having their own compounds, processes and 
machinery. An expert in insulated wire may know nothing about rubber 
footwear for example, and a man may know all about hard rubber products 
and know nothing about soft rubber. Further than this, two factories 
working under the same processes, with the same compounds and machinery 
and with equally skilled labour, are often unable to turn out the same 
product. This is because the business is full of secrets. It follows there¬ 
fore that when the manufacturing expert or rubber chemist is called upon 
to read a paper at such a Congress as this, there is much that he is in 
honour bound to suppress; all the manufacturers and chemists know it and 
appreciate it. It would be so with rubber planting if it could be done in 
factories under lock and key. The value of such a Congress as this lies 
chiefly in the meeting of the plantation chemist and the rubber works 
chemists, and the personal exchange of views. During this Exhibition, 
scores of such meetings have occurred, and the resultant good, to both 
manufacturer and planter, will be incalculable. That such meetings have 
been possible we must thank the very excellent management of the 
Exhibition, of which we all do well to feel proud.” 
These are only two out of many hundred expressions of opinion 
regarding the 1908 Exhibition. The 1911 Exhibition will be under the 
same management, and Exhibitors may rely upon every effort being 
made to ensure their comfort and that of the visitors to the Exhibition, 
so that trade may be promoted and the knowledge of the great Rubber 
industry extended. 
At the close of the last, it was proposed to hold the Second 
Exhibition in September of 1910, but objection was raised not only to 
the month but the year, and June of 1911 was selected, and seems to 
meet with general approval, as most of the visitors and exhibitors from 
long-distance countries prefer to be in England during May and June. 
On this occasion, the Exhibition will extend over a period of fifteen days 
against twelve in 1908. 
The management are again making arrangements for the holding 
of conferences and the delivery of lectures and addresses on “ Rubber: 
its Uses, &c.,” and other cognate subjects. It is hoped that producers, 
as well as the trade generally, from all parts of the world, will attend 
such lectures, and, by taking part in the discussions, contribute to the 
general knowledge of the various matters dealt with, and these 
discussions will be published after the close of the Exhibition. 
EXHIBITS.— A classification list of exhibits will be found in 
this booklet, and while not being a fully detailed list, the headings 
cover everything connected with Rubber, and materials or articles 
necessary to procure, preserve or assist in the production of the 
manufactured article. 
A display of the kind suggested is quite certain to embrace an 
extraordinary variety of specialities. The evolution of the almost 
numberless articles, wholly or in part made of Rubber, from the raw 
material, will constitute a source of interest not hitherto enjoyed by 
the public. Rubber producers in various quarters of the globe are 
taking a keen interest in the Exhibition, and have intimated their
