About Economizing Gas

A gentleman who has investigated the subject makea the following statement concerning gas and hnw to economizo in using it : " 11' a flamo consumes cight feet per hour, giving the light of sixteen candles, and this be redueed to six feet (threcfourths), then instead of the light ing equal to twelvo candles, the theoretical proportion, it will bo equal to cight candles, caushig a loss of thirty-six per cent. Ko on until lastly, if the flamo bo redueed to one and one-fourüi feet per hour, a gmall blue flaine will bo seen, giving no avilable light. If you have four two and one-half feet jeta in your room, making a light. equal to ten candles, throw the four into one, making a tenfoot burner, and you will got a light equal to twenty-cight candles. Mr. Williams Richards, an English writer on this subject, furnishes the following ing table Hlustrating the true proportion between the amount of light produced and the amount of gas burned iu an ordinary fish tail burner - and the table is indorsed by the engineers in the New York gas houses : Burner consuming 1 1-2 fcet gives light of one candle. Burner consumiug 2 1-4 ieet gives light of 2 2-3 candles. Burner consuming '■' 1 2 feet gives light of G 1-2 candles. Burner consuming t 1-2 feet gives light of 10 candles. Burner consuming ö feet gives light of 12 1-2 candles. Burner consumiug 7 feet gives light of 18 candios. Mr. Richards saya theaters lighted by 200 small jets, consuming 250 feet per hour, and giving the light of 200 candles, can bo lightod as well with eleven seven-foot burners, which would use only seventy-sevon feet of gas per hour - a sa ving of 172 feet. If you want a small light, havo a big burner and turn it down, for gas coming through a largo orifico gives more light than when forced thiough a small one. Light is also diminished py using globos, especially if ■of ground or painted glass, the latter destroying CO per cent. of the light."
