Whether one should he optimistic over the future of the automobile in- Austry In America is simply answered when one has the facts at hand. Last vear. the peak vear in production, there were $9.000,000,000 on deposit in savings banks, over $4.500,000,000 in building and loan associations and $70.000,000,000 of life insurance in force. The wholesale value of motor vehicles produced was $2,920,000,000. Adding dealers’ profits, war excise taxes and freight and delivery charge: the public spent approximately $4.100,- 000,000 in buying 1925 automobiles. Despite the constant increase in the value of cars sold, the public con tinues to carry a larger bank balance, more life insurance and more bufld- fng and loan. And this does not take into consideration the vast amount of money infested in real estate and c ation: IKOl The demonstrated quality of Oldsmobile extends to the smallest hidden part.

America i§ not as yet hocking its shirt to buy its car. If figures mean anything, it is the automobile {tself that is making for its great financial independence. 'Tis Folly to Be Wise. Knowledge {8 not always an asset in safe driving. There seem to he some things a driver is hetter off not knowing. of train times. One can walk into trouple by being too well posted. Knowing train schedules suggests paying no atten- tion to the tracks at other times. The driver may be the victim of his own wisdom. His watch may he wrong or the train may be ahead of schedule, or late. __There is really little point in know- ing speed laws. Common sense is the better rule. Wise drivers are get- | ting away from copsidering speed regulations and, A!f“e from “fine milla," “speed traps” and graft, most cases are heing settled on a basis of the recklessness involved, if any. For Sake of Safety. Straddle at least one of the spokes of the steering wheel with the fingers when driving fast. front tire will have less chance of tak ing the steering wheel out of your hand. Try to keep as many of the windows down as possible when motoring in the closed car. Opened windows are the best kind of safety glass. Keep the horn motor clean so that the: merest touch of the button will bring a response. In an emergency there is no time to te lost in horning. A lean mixture is more economical, but always more dangerous, than a rich one. Fall Makes Mileage Fall. Gas mileage is on the decrease at this season of the vear and should not show any signs of improvement until Winter comes. It is a difficult season for the engine, particularly so because owners do not appreciate it. Many a car that stands in a heated garage on Winter nights has to stand for temperatures of 40 degrees or low- er during the Fall. The owner expects a quick start in the morning, forgets to enrich the mixture to suit the new conditlons and chokes excessively to make the engine perform the way he thinks it should, Many engines during Fall are run- ning too cool all of the time. Thers are just enough hot days to make radiator coverings impracticable, but in the meantime low gas mileage be- comes the rule through excessive cool- ing. Did You Know That— Only one-third of the petroleum pro- duced in America is used to make gasoline to run automobiles?

Cause of Wheel Wobble. Worn or loosely adjusted parts are not always to blame for front wheel wobble. Loose front spring clips, ex- cessively large tires, tires of unequal | weight, sagging rear springs, worn shackles or broken leaves may be the cause of the trouble. Three Traffic Tricks.
