The effect of research and invention in increasing the manufacture of rubber goods, other than tyres and. tubes, receives attention.in a recent issue of "The Index." The wider use of rubber for machine and engine mountings. is now extended to the erection of locks on canal projects, in sealing sewer pipes and in lining metal chutes handling rock. Rubber conveyer belts are considered to save costs in industrial operations. New rubber paints have been developed, improved rubber hosing has been found useful in the mining industry, rubber thread is being applied to the manufacture of clothing and it is estimated that 37 per cen' of the rubber industry's entire output, in 1935, could be classified as "rubber goods other than tyres, inner tubes and. boots and shoes" and amounted to U.S.$249 million. The conclusion reached by the American journal is that the limit of new uses has riot been reached:
No such definite limits exist, however, to the potentialities opening up' through the new. uses of rubber. Equipment of tractors with the newly developed tyres suitable for farm machinery, and rubber for automobile upholstery constitute two fields of expansion which may prove as important as the original automobile tyre business itself. The widening application of mechanical goods to so many phases of manufacture and the countless miscellaneous uses of rubber in building, home equipment, and clothing may prove to have almost equal possibilities. With research and product improvement continuing, the opportunity ies of manufacturers of rubber products appear distinctly encouraging This is obviously encouraging to the supporter of the industry, but the wise man will proceed cautiously and rather count the gains achieved than be inclined to stretch his imagination overmuch in calculating the possibilities of the future,
