Still, all things considered, I know no better or more economical method of heating the rooms and providing hot water in a household of any size than the coke furnace. This I should not say were gas and electricity cheaper, because, of course, a water heater which is set going by turning a tap or switch is obviously more labour-saving than a furnace. In almost all households gas or electric heaters are practical, because if used carefully they are not too expensive, and in small houses or flats where the mistress is her own maid, or depends upon help from a visiting worker, I should certainly recommend the abolition of either coke or coal from the labour-saving point of view alone. [Illustration: _PLATE XXXVI_ AN ELECTRIC COOKER SUITABLE FOR ORDINARY USE Oven, grill and toaster plate, warmer and hot plate. (Messrs. Crompton & Co.)] Some Figures. I find that in the two years we have used the furnace we have consumed 120 sacks of coke, but part of it was mixed with the coal burned in the drawing-room. I must also admit that during part of this time the fuel was carelessly used. In addition to the coke burned in the furnace, coal was needed for lighting it. We used nine tons of coal in two years, for the drawing-room fire (a large old-fashioned, extravagant grate) and for the furnace. These were partly war years, and coal cost on an average 35s. a ton, and the coke 1s. 2d. a sack; roughly £11 10s. for furnace and drawing-room fire per year. In addition, the gas bills for two years have been, for cooker and five fires (one of the latter lighted in dining-room for about three hours a day, another burned a good deal in Christmas holidays, fire in servants' hall used in the afternoon in cold weather, and two bedroom fires only for an hour or two in the evening when _very_ cold, except during a three-weeks' illness, and one or two days when people had colds), about £40. Gas is at the war price (in London) 3s. per 1,000 feet, and (for "war reasons") inferior in quality to what it was before the war, and the figure includes meter and stove rent (two stoves, kitchen, and servants' hall). When considering these sums it must be remembered that this is a small London house, and that the furnace in the kitchen heats that and keeps the smoking-room above from ever being very cold. The large radiator in the hall, heated from the furnace, makes an enormous difference to the warmth of the house; also the drawing-room fire was not lighted in the morning except in really cold weather. To the coal, coke, and gas bills must be added 14s. worth of wood during the two years. Old boxes were chopped up, so that if all the wood had been bought it might have amounted to 18s. or £1, say £32 10 0 for a year's fuel. Had we used a coal range and coal fires and had no radiator, I calculate that the cost of coal would amount to at least £35, and that we should have used more wood, and certainly we could not have run the house without more help.
