Letter from Admiral of the Fleet 1st Lord Fisher [Chairman, Royal Commission on Oil Fuel] to WSC [First Lord of the Admiralty] on the Commission, particularly meeting with Dr George Beilby on the possibility of producing oil from coal. Fisher asks WSC to keep the letter "deadly secret and never mention it", stating that it was not a dream, nor the "outpouring of a diseased imagination".
