§ Mr. Purbrickasked the Minister of Supply what is the approximate amount of rubber used annually for the production of golf and tennis balls; and, if these were returned after being used, to what extent could their rubber contents be re utilised without any material loss of rubber?
§ Sir A. DuncanThe tonnage of rubber normally used in the manufacture of golf and tennis balls is not large, but in the present emergency even small amounts are important. Old tennis balls can only be used as scrap. The original rubber core of golf balls is being used again inside a new gutta percha cover, but supplies of gutta percha may not suffice to permit the continuance of this practice.
