 Rusty rims are responsible for lot of damage. They corrode tubes, making tire changing difficult and the tire to freeze" on, Moisture is bound to work in any type of rim. But it's effects can be nu1hfed by care ful periodical inspection of your rims. They should be cleaned up at least once every six months and treated with graphite. Ordinary paint will not suffice, as the heat generated by the tire will melt the paint and the to use graphite.
 Tighten up the bolts on the wedges that hold the rim to the wheel. at least monthly. Any car owner who takes the time to inspect his rims periodically and keep them in good condition will certainly save himself both trouble and money"
 The third big automobile race of the present season, at the Chicago speedway, June P, resulted in a nota- ble victory for the veteran driver, Louis Chevrolet. Fully thirty-fiv thousand people, the largest crowd ever assembled at the Chicago track. watched the flying Frenchman. speed way champion of 1917, whizz around the two-mile course in his maroon Frontenac, 100 miles in 55 minutes, 29 seconds, an average of 109 miles an hour.
 Chevrolet's victory was possible be- cause of his freedom from tire and me chanical trouble. He assumed the lead early in the race and was never headed off, although closely pressed throughout by Ralph Mulford and Ira Vail
 At the start Ralph De Palma, Dario Resta and Louis Chevrolet ruled as favorites, but mechanical trouble forced De Palma and Resta to the pits, allowing Chevrolet to pile up lead which could not be overcome. His vic tory was also a notable one for the straight side or mo hook" type of cord tire, for his trusty Frontenac was equipped with tires of this type. That racing drivers are discarding the old theory that none but a clincher tire would stay on the rim at racing speeds, is indicated in the use of the straight side type by four of the noted drivers, Chevrolet De Palma, Resta and Vail, at Chicago.
 In starting the race the handicap system was used. De Palma was placed on scratch and handicaps vary ing from fifteen to ninety seconds ex- | tended to the other drivers, based on the speed Of their cars. This method | has been found the most satisfactory | in providing an equality of oppor- tunity to all the competing drivers, 1 and will be followed in all of the big racing events of the season. The drivers finished in the following order: Chevrolet, Mulford, Vail Hick-
  De Palma and Mcbride.
 It addition to the big event a i three heat ten-mile race was run Resta took the first heat and Chevrolet the second. The three fastest cars in these two heats qualified for the third heat, which was captured by Resta in a spectacular finish, at 109 miles an hour.
 A new track record was established by Ralph De Palma in a special ex- hibition lap, hls time for the two miles, being one minute, two and two- fifths seconds, an average of 116 miles an hour, three miles better than Resta's former record. This was not 1 the fastest time of the day, however, for in the big 100 mile race De Palma reeled off several intermediate laps at the rate of 120 miles an hour. The terrific pace set in the after noon's events is indicated in the con-
 dition of the track after its close. In places it had the appearance of having
 been sprlnkled with kindling wood,
 torn from the track by the flying cars.
 At times a swirl of splinters would
 follow in the suction of the cars as
 they stormed by the grandstand. At
 the finish of the race the radiators of
 several cars were almost covered with wood SDlinterS that had been SIlcked
 from the air by the fans.
