matter, when these individual leak ages come to be multiplied by B. 00,000, the total number of car own CTS in the country, the condition as- ; lmes quite a different aspect. If every motorist in the country wastes half a pint of gasoline a day, the to- tai leakage is 312,000 gallons each 24 hours, which is unquestiOnably a seri- ous situation. Therefore it behoves every one of us to eliminate all waste.
 Watch Carburetor
 The first point of attack in the campaign to cut down fuel consump- ton is the carbureter. It has been said that the average car owner runs his engine on a fuel mixture nearly twice as rich in gasoline as it needs to be, in fact the engine will give its best work on q mixture as lean as possible. Practically all modern car buretors have q wide range of ad- justment, so that all the lair needed may be gotten by adjusting the in strument itself. It is a very simple matter to set the carbureter for more and more air until the mixture is too thin for proper operation and then turn back until the engine is running smoothly again with maximum ar intake. This question of fuel mixture is a very important one, since Ii American motorists habitually ran on a mixture that was twice as rich as need be, the consumption of gasoline would be just twice as great as the actual needs. In the interests of pa triotism, then, let every car owner make sure that he is using a mixture just as lean as is consistent with proper operation Moreover, the en- zine may actually run better on the Ieaner mixture, to say nothing or the reduction of carbon deposits that vii | ensue.
 investigate
 Having adjusted the carbureter tC 1 supply the proper fuel mixture, th' entire fuel system ought to be gon' over. Dirt in the pipe, rust in tn strainers or foreign matter in thu gasoline tank, help to cut down tn | efficiency of the whole engine. Leak in the system should be careful. hunted down and eliminated. Thi means not only actual leaks bu power leaks for wasted power mean additional consumption of fuel t make good the deficiency.
 In this category will be found muffler clogged with soot, resulting in back pressure, which cuts dow the efficiency of the engine. Carbol deposits in the cylinders cause vast of power and excessive consumpuol of fuel. It will be noted that thl | problem of fuel waste is cumulativ in effect. If the fuel mixture is 10 rich. it not only wastes fuel directly but produces carbon deposits in tn | cylinders and soot in the muftlel which causes further useless dlsslpa tion of the fuel energy. In conec | ton with carbon deposits, it migh be desirable to install one of the va 1 poring devices, which inject wste vapor into the combustion chamber | While these vaporizers do not remov carbon deposits that have alread formed. they do tend to prevent flu ! ture formations. | Improperly seating valves are an other source of power losses. The should be accurately ground m, a intervals or whenever any doubt ] felt as to their condition.
 Heat Necessary
 With the present day grades or tue if is important that all possible hea shall be used in the process Of car | huretion. Various methods of carry ing the heat of the exhaust to tn inlet manifold to insure the thoroug yaporization of the heavy gasolln that we get today. The motorist wn is using an engine without equipmer for utilizing the heated air for tn process of carburetion, should have device of this sort installed.
