When the car is stationary (and the engine running) always endeavour to run it as quietly as possible. It is sometimes annoying to people to have the noise of an automobile outside their door and no good can accrue by allowing the engine to run on unchecked. Underneath the steering-wheel, on the steering-column you will notice the throttle-lever, mentioned in the preceding chapter. Its function is to regulate the mixture in the carburetter. When you wish the engine to run very quietly and slowly, you move this little lever from right to left. When starting to drive again do not omit releasing the throttle, otherwise the engine may stop owing to insufficiency of gas. Your next move is to take off the side brake. You will find this lever on the right-hand side of the car. Now you are absolutely ready to start. Always remember that a car should receive careful treatment, so therefore do not attempt to move anything by jerking it roughly--take everything very quietly. You will notice two pedals on the left and right respectively of the steering-column, on the floor. The left-hand pedal acts as a throttle (shutting off gas) in exactly the same manner as the hand-throttle explained above, that is, when it is pressed down half-way--and the throttling process acts according to the amount of pressure put upon the pedal. [Illustration: _Photo. H. W. Nicholls_ RELEASE THE FOOT FROM THE RIGHT PEDAL AND THROTTLE SLIGHTLY WITH THE LEFT FOOT ON THE LEFT PEDAL] If it is pressed down still further it acts as a brake. This foot-throttle and foot-brake are more frequently used than the hand-throttle and hand-brake.
