after the demands of the U.S.S.R. and the Empire rubber, have been met, is coming to this country, but if appreciable quantities of synthetic rubber are shipped to the U.K. in the last months of the year some adjustment may have to be made in the Ceylon allocation for the fourth quarter. Inevitably difficulties will be encountered by our industry and that of the United States in the change-over from the use of natural rubber to that of synthetic. Even when synthetic comes forward in bulk it will be desirable to have a sufficient proportion of our supplies in the form of natural rubber for use in making particular articles or for mixture with synthetic.
