Theflame from the burning alcohol willheat the generator in about a minute. When the generator ishot, the needle valve 5 is opened slightly, by turning the lever6, and the gasoline vapor under high pressure blows into thetube 7. As the gasoline vapor is blown into the tube 7, air isdrawn in through the opening 8, as indicated by the generator is practically a large Bunsen tube from whichthe mixture of gasoline vapor and air is conducted to the burnersby a connecting pipe. Gas machines operated on this principle are made to accom-modate a definite number of lamps. After the lamps are lighted,the amount of gas is regulated to suit the number in use. If atany time it is desired to reduce the number of lamps in opera-.

As an illustration, suppose that a plant of ten lamps had beenburning and that it was desired to reduce the number to six;four of the lamps are extinguished by turning the levers C, whichcontrol the gas-cocks. The generator which had been supplyingsufficient gas for ten fights wifi continue to produce the sameamount until the lever 6 is turned to reduce the supply of gasofineto the required amount for six lamps. This is done by graduallyclosing the valve 5 until the lamps again burn brightly. In small plants the least number of lamps that will worksatisfactorily at one time is three. Automatic regulators are made for plants of consider-able size but do not satisfac-to
