§ Sir J. WARDLAW-MILNEasked the Under-Secretary of State for Air to what extent the Air Ministry have adopted the policy of installing Diesel oil engines in place of coal-fired boilers; and whether the Government will reconsider this policy in view of the desirability of extending the market for British coal instead of increasing the country's dependence upon imported oil?
§ Sir P. SASSOONThere has been no displacement of coal-fired boilers by Diesel oil-engines in so far as concerns the Air Ministry. The second part of the question does not therefore arise.
