SEVEN WEEKS' RUN.]

Stock Nash Cars Perform Well.

OVER 50,000 MILES.

Konbahn, Wisconsin (Specfii})--- Using the wide open spaces of the western United States as a complete proving ground, Nash englnicera | have just completed a spectacular, seven-weeks' open run which took six new cars of the Nash 1931 aeries, picked at random from the. loading docks, over a total of 50,581 miles of the hardest driving avail- able in the country. The cars came back to the headquarters with every performance detail checked -and double checked and with every ordeal which may be given them by the roughest motorist- success: fully completed.

Piloted by members of the engineering departments of the Kenosha, Racine and Milwaukee, Nash plants and accompanied by abservers from the factory service department, the Senman Body Corporation, and the factory sales department, they made the run to Denver, Colorado via the Lincoln Highway and, Vic tory trail with a unit average of 46 miles an hour.

Six days were spent in the Denver territory in mountain driv- ing and in altitudo calibrations, with the cara negotiating such grades as North Cheyenne Canyon road.

The caravan then dropped down

to Colorado Springs and headed through mountains, sand and mud to Salt Lake, crossing the desert to Reno and continuing to San Francisco after exhaustive trials to prove cooling efficiency. At Fresno, two of the cars set new climbing records by sailing over the top of Toll House hill, which is Beven and one-half miles hard pulling, in high gear.

After these hill checks. the caravan took the road to El Contro- in the Imperial Valley and attacked the old ocean bed which lies 100 and 150 feet below sen level, in temperatures ranging up to the average summer heat in the middle- west, before making a five-day run back to headquarters via El Paso, Dallas, Little Rock, Cafro, and the fast pavements of linola. Speed trials exceeding 80 miles an hour, and also long hours of sustained, high speeds were accomplished by all of the curs.
