Keeping Down Cost

"Measure Out" Electricity FLPECTRICITY is measured in "watts" in exactly the same way that. water is measured in gallons. Just as it takes eight pints to make one gallon, so one thousand watts make a kilowatt. A kilowatt used for an hour is a unit. A 40-watt lamp consumes 40 watts of electricity in an hour, and this divided into’ 1000. shows.the number of hours it',will burn on a.unit. Here it is 25 hours. A 500-watt iron consumes half a unit an hour and will burn two hours on one unit. A Tradiator marked one thousand watts uses one unit per hour, but heatng, of course, is charged at a much reduced rate. : It will be seen that by judiciously selecting suitable lamps one can materially improve the lighting of the home without making for extravagance, It is foolish economy to restrict the num-~ ber of switches or the number of points, as electricity is anything but expensive,
