§ 40. Sir J. D. REES
asked the Chancellor of the Exchequer whether, in view of the expenditure of coal in the Government offices, experiments have been or are being made with coal-savers, such as seldonite or other compositions claiming to retard the combustion of fuel, in view of the need for the conservation of the supply of coal in war time?
§ Mr. McKENNA
I understand that for several months experiments with seldonite and other preparations of rock salt, etc., have been conducted by the fuel experts of the staff of His Majesty's Office of Works. Experience has shown that the most effective method of reducing the consumption of coal in Government offices is to reduce the area of the fire grate, or, in the case of central heating, to lower the usual temperature. These measures are being taken generally throughout the Civil Service, and already considerable economy has been effected by their adoption.
