It is the watch- dog of the battery and tells the ob- servant motorist nearly everything that is taking place.

The fuel system provides the gas line, vaporizes it, mixes it with air in proper explosive proportions and delivers the mixture to the engine. The ignition system sets fire to the compressed gas in the cylinders at ,the proper time. It-has been the study of experts for many years to get a hot spark at the proper time lin each cylinder, and although the |3atem is very nearly perfect it still requires constant care to keep it at all times at its best. The oiling system supplies a fiim of oil between all the bearing sui faces of the engine, and so reduces friction and loss of power and, of course, prevents the parts from heat- ing amd “seizing.” 3 The cooling system prevents the cylinders from becoming so hot that they will burn up the oil and damage the moving parts. The starting and lighting system is a recent development which is now considered a necessity. It enables us to crank -the engine by pressing on a.pedal instead of spinning the start- ing handle by hand. This pedal closes rl switch so that the current from the battery passes into an electric motor, called” the “starter,” which cranks the engine. As the starter and the ignition system use a great deal of current, this must be replaced as fast as used, and therefore a generator / is provided. Ags the battery has am- ; ple capacity, it also provides current for the lights and the horn. Transmission. -(2) The transmission is the set of parts which takes the power from the | power plant and delivers it to the rear iWheels. It consists of the clutch, { which is merely a convenlent means |of connecting and disconnecting the engine and °the transmission: the change speed gear set, which gives us the different. forward speeds and lhel reverse; the universal joint (one or two); the drive shaft: the differen- tial, which drives the rear wheels at different speeds going around corners and at the same speed going straight, and the live axles, which deliver the power to the wheels. _ We stand back of every sale with our unquali- fied guarantee to serve you right.

The Steering Mechanis; wearing more than it should, see if the front' wheels are out of align- ment. Running against the curb or other obstacles will bend the steer- ing knuckle arm and throw the wheels too far in toward each other. They should toe in slightly. If not properly set the tires will wear rap- idly. Never use a cloth to wipe dust off the fine finish of the car. This dust is a fine grit, and the cloth grinds it into the surface so that it soon be- comes dull. Use a fine ‘hair duster if you are in a hurry, but the best way to remove dust is to flow water over it. The first flow softens the dust and mud, and the second flow removes . Then a_solution of a high-grade linseed oil soap is used to finish the cleaning, the whole sur- face being thoroughly rinsed before drying with a chamois cloth. Try the fan occasionally to see if the belt is tight enough. 1f the blades can be spun around the belt is loose and the engine wil overheat. If it is so tight that the blades can hardly be moved there is danger of snapping off the blades when the engine starts. If the belt is tight enough o tha the fan will slip with a slight effort it is about right. By all means cayry a small fire ex- tinguisher on you car, and keep it in some place where it is easily ac cessible. Besides lowaring the n- surance rate it gives you a feeling of confidence. In case a fire starts around the carbureter begin at the bottom and work up. If there is burn- ing gasoline on the ground under the car put that out first, otherwise it will set fire to the gasoline above as fast as you extinguish it. 8 Some drivers do not realize the ne- cessity for+ keeping the spark well advanced at all times. The rule is to advance the spark as far as it will stand without knocking. This uses the full length of the power stroke and so requires less gasoline. Try this experiment: While running at a fair speed on a level road, retard the spark. The car will slow down. Now open the throttle enough to get back .

To increase the mileage of a tire! it should be inflated to a greater pres- sure, This is invariably the rule, as the average motorist does not carry enough air in his tires. Increasing air pressure, of course, decreases the cushioning ef- fect of the tires, so to maintain proper air pressure and enjoy cushioning so necessary to comfortable riding, change to oversized tires. The oversized. tire need not be inflated to as great a pres- sure as the tire considered as standard for the car, as the former is built to carry a greater load than the latter at the same number of pounds pressure. ‘Thus with less inflation you obtain more cushioning from the tire, with no dan- ger of shortening its life by under in- standard size tire.
