Not illustrated. 1910 edition. Excerpt: ...early ignition accelerates the speed by giving a more powerful explosion. So in going uphill, as the force of gravity slows the revolutions of the motor per minute, the spark lever should be set back gradually notch by notch, so as not to explode the mixture before due compression in each cylinder has been obtained. On topping the grade on to a level stretch or slight decline as the engine begins to pick up again the spark must be advanced to meet the moment of proper compression. It shows an utter lack of brains to run with the spark lever always at a fixed point, since with a slow running engine the mixture is exploded before being properly compressed, and when the revolutions per minute are near their maximum, the firing is too late. In both cases the cylinders become overheated and a strain is put upon the crank shaft, while power is distinctly lost. Never retard the ignition in order to slow the engine and check the speed of the car. You will burn away the seating of your valves, overheat your exhaust pipe, and perhaps blow out the asbestos washers near the cylinder wall. The throttle or the switching off of the ignition altogether are the only legitimate means of cutting down your engine's speed. These are but a few of the basic operations in motor driving and indicate how the automobilist can study things out for himself, if he has the laudable ambition to drive with brains. The subject opens up a wide field of study and thought for the careful driver, and no driver can afford not to be careful if he desires long life for his car and himself. Once the motorist has assumed the brainy attitude in his driving he may be safely r trusted to acquire for himself a wealth of knowledge which will make him indeed an expert, capable of more
