        Output of the older French plants for the manufacture of synthetic petrol is to be augmented by several new establishments, the annual output of which is apparently to range 30,000-100,000 tons of petrol.  Apart from importation of petrol, the importation of crude petroleum for refining and for the hydrogenation of residues will continue to be normal practice, the synthetic manufacture is to be developed to meet emergencies.  The national resources of coal and lignite do not permit such development as in Germany, where the present production of nearly 1,000,000 tons of synthetic petrol per yr. is to be quintupled within the next 3 yr.
