Why Spend $2-$1 Wi] Tests made last September at Cleveland, O., with five 2-ton White Trucks carrying full load, showed that on an earth road in fair condition, gasoline consumption was twice that on a concrete road. The diagrams to the left and right illustrate the relative quan tities of gasoline and its cost, used by one truck in making a Ioo mile run under the same condition of load over the two roads ig pictured above. Think what 5,ooo,ooo motor vehicles would save in gasoline alone if they always traveled on concrete. S Since one gallon of gasoline will carry you twice as Far on a concrete road as it will on an earth road, why waste the other gallon? You pay the price of good roads whether you get them or not, and if you pay for concrete roads they pay you back. Let's Stop This Waste! Illinois, Pennsylvania and Michigan have voted big, road bond issues to do away with the mud tax. Many other states and counties are going to do the same thing. When You Think of Roads-Think of Concrete; When You Ride-Ride on Concrete Write our nearest District Office for free copy of "Concrete Pavements Pay for Themselves" and "Facts About Concrete Roads."
