Finally, I take the opportunity of recording my thanks to all who took part in the investigation of the explosion, including officials of the National Coal Board, the Nottingham Area and local Branches of the National Union of Mineworkers and members of the staff of the Inspectorate, also to staff of the Safety in Mines Research Establishment for examining and testing impounded safety lamps and electrical equipment.

I would also like to record my appreciation for the excellent and ready way in which the plans have been prepared by Mr. L. H. Watson, Area Chief Surveyor, and his staff.

I have the honour to be, My Lord,

Your Lordship's obedient Servant,

A. Winstanley.
