According to Mr. Williams, It coKt more to lay the usphalt or brick for a given dentil than It does for the samo depth of concrete. Thcrcfoic, brick and asphalt have no chance of being eoinnetftors for service on n motor truck highway, oh the concentrated loads placed upon the wheels when the heaviest truck ate considered run as high oh from four to eight tons under a single wheel. The crushing bearing value of the concrete at 3(100 pound per square Inch Is nble to carry the load, but the bearing value for many subsoils Is not. Mr'. Williams said that many rem edies have been offered for correcting road failure. One of them Is that on clay or alluvial -soli subbascs thers should be placed a cushion three or four Inches thick of porous material, such as land or cinders, that will permit the suDuase 10 iirain mil nud remain in a more unlfnim condition under varvlng I weather conditions.

The enormous appropriations for highway work already made by states and mtiuiclpnlltrA, appropriation tlmt total more than ouo billion dollars ac cording to the most reliable reports covering bond issues and direct levies for road bul'dlng and road maintenance, presage, It is believed, an unprecedented volume of road-building for 1021.

In addition, funds obtained from direct levies nud other sources of state rcc nuc and countv Issues nre estimated to amount to $21)0,200.000.

Motorists had grown weary of adjust ment wrangles and they were looking for a tire that would perform as perfectly on the car as it does in the advertising. And this could only come from the dis covery of a process that involved none of thd risks of mold-pressure curing. Such a process was discovered and perfected. National Speedway Tires are built on a col lapsible core which is taken out before the casing goes into the mold. Then a newly devised inner tube is inserted into the tire and the mold closed. No external pressure is exerted on the mold; it closes of its own weight. Next, by a most ingenious means, the spe cial inner tube is rilled with water until it attains a pressure of 200 lbs. to the square inch. This internal pressure is maintained until the tire is thoroughly cured. During the entire process not an ounce of external pressure is applied. Hence distortion is impossible. The tire comes out a perfect, flawless, solid-molded unit, ready to deliver the limit of uninter rupted mileage. Pinching," bruising, bead displacement rim cutting these things simply can't happen under internal hydraulic expansion NATIONAL SPEEDWAY TIRES have found the aukk route to customers' good will Local Distributors f WKDNE8UAT, UHVMlWriOSl" ""a"tTir!!I?TTTrT!?,,,H,"B"""-'' ii L M amrrumt: mi mmm .. -2f!J I r FWF iwljiitiHiiHHiHiiiMiiiiiiiliiiiiiiiiiiiiiiiiHiiiinimH iiiimi mmmnnw 111111111 in. ppf p,, , Illlllllllllllll(l , 23C 3 Local Distributors mil iiiiiiiiiiiiiliiiiiiiiiiiiiiiiiiiiiiiiiiiiiisiiiiiiiiiiijiHiiiii 1 m 1 s A i-J.UK( M,
