 MANY RACING MARKS
 FELL DURING 1911.
 The gasoline fan finds some interest ing material in a review of the six teen years of ups and downs of auto
 mobile road races, with honorS start | ing with the Panherd, and now rest ing with the National. Back in 1895 the Chicago Times -Herald'' race was win by Duryea, distance seventy miles, with an average of 7-5 miles per hour. This was considered great at the time,
 held that same year, the Paris Bor- deaux-Paris event, 1192 kilometers, won by a Panhard with an average of 14.9.
 From there on there was a general per hour up to 1901. During this time there were ten races, six of which were won by the Panhard. A Morse Car forged to the front, however, in meters in 1901 with an average of 5S.3
 miles per hour.
 There was relapse in speed from this high mark then through five diff ferent races down to the Gordon Ben nett race in 1902, of 6092 kilometers,
 won by a Napier with an average of 34.3 miles per hour. The next race. the same year Panhard "came back and won the Circuit des Ardennes, 512 kilometers, with an average of 54.3 miles per hour. This record he'd for one year. In the same race next year the Panhard showed this average up to 6fty-seven.
 The big jump came in 1904 when a Fiat made an average of 72.0 miles an hour in the F1orio Cup race of 373 kilometers. This mark remained se- cure until 1908. During. these four years there were some radical shift ings up and down. In 1906 the av- fN 4lee an hour. In 1907 the Fiat was able again to shove the average up to 70.6. And this held until the Fiat again made the record with an average of 74.15 in 1908. And this record remained secure until Harvey Herrick in a Ma tionaI lowered it at Santa Monica this year with an average of 74.63. Be- tween these two big high marks there were twenty other races, all of which failed to lower this mark. In 1909 at Roverhead, L. L, Chevrolet in a Buick reached seventy miles an hour, and Benz reached 70.55 in the Grand Prize in 1910. That same year a Lo- zier reached 71.S0 at Santa Monica
 The two most remarkable perform ances in the history of racing can be credited to 1911. One the mile made by, Burman at sDaytona last April in 25 40, the fastest ever travelled by man, will no doubt stand for some time. hour, which is crowdins on the much coveted three miles g. minute.
 The performance of Ray Harroun at Indianapolis last Decoration Day the greatest test of man. machine and regular stock tires the. world has ever known.s He travelled 500 miles at an average speed of nearly seventy-ave miles per hour on a brick oval track with three of his tires untouched This is considered a worlds record for both tires and car. In addition to the above, all straight-away records from oE ka al G. tained speed ranging from eighty-nve to seventy-flve miles an hour, nearly all on American cars
 COMMON SENSE
 IN USE OF TIRES.
 To enable automobile owners to ob- tain best results, the following as the nine most important ways in reducing tire expense are suggested:
 First-Always use large sized tires. Buying small ones is poor economy. A small tire can't do the work of a large one. Never overload tire. It's bound to give way and cost you more in the end.
 second-Always keep the tires we'll inflated. One of the first requirements of a pneumatic tire is air-cheapest made to do it's work upon air and a given amount. This gives you speed, lighter draught, fewer punctures and blowouts etc. A tire should always be inflated until it stands up perfect ly round at the point of contact with the ground when the car is loaded. This generally takes about ten times the cross section of the tire. For in stance, four-inch tire would require pounds pressure.
 Third-Repair cuts and holes in tires "A stitch in time saves nine" is so than brooches. If you don't have them. promptly repaired, the dampness and dirt win get in and soon rot the fabric, and then comes blowout of course.
 Fourth-Keep your tires away from oil. oil soon softens the rubber can't help it-and the tire can't pos escaping from your car in a garage run and stand about the tires. Nor let. your car stand in oil pudd,es on the street. A little more care of the ends or in the use of heavier grade of oil will save tire money.
 Fffth-See that your wheels are run ming true. Wheels that run "sq-g-d' ment, soon ruin the tires There is a pulling on the sides of the tire-wallS, and something has got to give way. Keep the steering rod prop erIy adjusted.
 sixth-Keep heat. away from the tires as much as possible. Even the hot sun is very hard on tires. In garages keep the sun out as much as possible use heavy window shades. On leav- ing or stopping your car on the street. leave 1t in the shade wherever pos sible.
 Seventh-Bring your car to a slow and easy stop. When you throw your brake on hard and suddenly, even go- ing at a moderate speed, you throw a very heavy strain on the tire, and must injure it more or less. There is plenty of time to stop, and no necessity of tearing your car to pie ces merely to show how quick you can stop 1t. speed is most disastrous on tires
 Ninth-Keep out of the car tracks l The steel rails are constantly being worn and frayed by the car wheels, and slivers and sharp edges are left on the rails. These soon cut the sides out of any tire. WALL STREET TODAY
