Lubrication. If you want to keep a new motor like new, or an old motor from getting older, givo it new oil. Tho best of oil geta dirty when left long m a motor, and replacing it with fresh will be moat welcome to tho motor. At the bottom of the crank case you will turn a plug which,may be unscrewed, allOTino- tho oil to drain off. Replace the plug and pour a.pint or more of kerosene in foiling system. Then, leaving the ignition turned off, run the motor ove? a few times with the starter or tho crank, bo that all the passages of the oiling eystem may he thoroughly cleansed. Then allow the dirty kerosene to run off, replace the plug nnd refill tho oiler with clean, fresh oil. If this process is repeated every two thousand miles-or oftener-much motor trouble will ho avoided. Goal Cas. "Coal cas has come to stay," says one of the leading English motor journsils, in its comment on the increasing use'of gas as a substitute for petrol, which is now almost unobtainable m England by private motorists. One ot the advantages rf using coal gas is tne great ease with which an engine can bo started on its as compared , with tne indifferently volatile fuels.available today. Tho explanation is a very simple one. The new fuel is already in the true gaseous form, and the mechanical admixture of the gas molecules with the air is obtained perfectly and without any extraneous aid, such as a. jet or choke tube. No liquid fuel-and present-day petrol least of any—pan on expected to form a perfect mixture. At beat the intermixed fuel particleg must be of appreciable size, a condition Which tends towards forming what might he termed a mixture, whereas with coal gas a "fine mixture must necessarily result; Furthermore, such a mixturo can bo maintained at an even density, which fact must tend to economy. In winter time the advantage of ooal gas is even more marked, though it should be pointed out that abnormally cold wpather may -possibly adversely affect the starting, a point which requires testing by practical experience. This fact opens up tho interesting possibility of the application of coal gas solely as a starting medium as an auxiliary to liquid fuel. There is no reason why a comparatively email gas container made of aluminium or-alloy should not be carried on all cars, even when equipped with an fileotric etarter, as the fact should not be overlooked that it is the quality, of the mixturo which is tho determining element in caso of start'ng.

An Excellent Lubricant. There soems to he a general belief among motor-car owners (says an American export) that graphite has its application only, as a lubricant for cents, joints, etc.; and not at all for the motor. This idea is absolutely erroneous; graphite is an excellent lubricant for use in. the motor, when the flake form, the proper one, is used in conjunction with the regular lubricant There are certain forms of lubricant which employ graphite in various combinations with oils, and these often are excellent for the motor, the graphite tending to fill minute depressions m tho metal. Here nnd There. It is impossible to keep the hands clean when making repairs on tho machine. A simple and economic way in which to cleanse them is .is follows: Mix a small quantity of sawdust and lubricating oil together and nib thoroughly into tho pores of the skin. _ J he oil should then be removed by wiping the hands with a cloth which has been saturated with a little petrol or■kerosene. This should be followed by the ordinary wash with soap and water. It is poor'practice to attempt to remove he dirt from ,the hands by bathing them in petrol, as this will cause somo of the. matter to become deeply imbedded in the skin. A soft or flat tyro on a front wheel alwavs makes itself, noticeable toi the driver, because it becomes difficult to hold the car in a straight course. If vou nro on a level road' and the car shows a marked tendency to turn to the' right, you will probably find that the right front tyre is soft. The pounding and bumping of a flat tyie will attract the driver's attention to a flat tvre on a rear wheel. TV not neglect to groa.se wheel hearings occasionally. They should no be nc'lefited because they are out ot qicht " The front wheels must be removal for this If « P™« «!ffl " provided for each rear wheel it wil be on the axle ho,,sin? next to the whee. If not, the wheel must bo removed. Neglected hearings mean loss of power and unnecessary expense. Wherever there w. metal rubbing neainct metal wear is bound to take place, and must of this c«n ■ be lessened bv ft illdicious use of the 01n Manv of the irritating S qi.e£ will automatically disappear and nding will bo much easier and smoother r the small parts are-given proper attention at stated intervals. Here is n novel, method «f repamne a bent headlight rim. if it is of nickel: ar^SefUth.]rfni and Hd.t tans force the; rim to assume tho shape, of the babbitt. The careful driver" never operates the enr with bis foot on the clutch pedal. There may ho only the slightest pressure' exertecl. but even .this may. be enough to deast the. clutch to slip just a little, which is too much.
