Results of four years' testing of automobiles, their air resistance and coefficient of friction between tires and road surfaces, made upon highways in vicinity of Iowa Engineering and Experiment Station; forces opposing vehicular progress are increased 50 per cent by light gravel road surfaces and total 700 lb. per ton in deep mud; discussion of Iowa State College -- Bul. no. 88, by T. R. Agg, of which see original article under Automobiles -- Operation Costs.
