Show t Public Highways Highways' I Tho good tood roads movement is seeing fJ i a big revival now that business Is f becoming normal The most Important Important tant program that has hns recently come cometo cometo cometo to our attention Is that of at the slate of Michigan which has just Jast voted In la lafavor favor of a n program that when carried out will place Michigan on the map big so far as ns goo good roads are concerned writes BIrkett L. L Wil wn- Williams liams truck sales manager for a larger largo large r motorcar corporation Everywhere else you yon see also more Interest In good roads rands than In any period In our history It Is true to say sayi l i that the war and Its needs taught us t the e value of oC good roads Perhaps It v did Perhaps It brought home to those dull ears cars of higher ups the Importance of an nn Intelligent system of navigable highways But more and more It comes home to the tho man who studies the situation that back of the r good roads movement must be the tho or- or 4 man the average man who pays tuxes taxes and votes and thinks as he N votes The farmer or rural ruml dweller Iri lri certain tain sections for a long time stood tI 1 In Inthe Inthe inthe the way way way-he he wanted the roads but he didn't want to pay for them He did not realize that In the long run ron good roads pay for themselves out of savings savings sav sav- ings made to the community In Ia haulage haulage haul haul- sav-I sav age of ot people and merchandise But I me we farmer larmer is reckoning In units of time Yes he realizes the Value of min mIn mIn- ates throughout tha the season season and and he Is just as keen In conserving time as the city-bred city man who operates a big factory factory factory fac fac- tory If anything he hc Is a bit keener for seasons do not not wait walt and crops must be sowed and cultivated reaped and marketed at the right time He has convinced himself that time Is money And he knows that good roads save time and that they save time largely because they make It possible to get satisfactory services from motorcars and And he is not one bit blind to the fact that operating cost costIs Is largely Influenced by road conditions condi condi- that Lions that good roads make gasoline more elastic rubber and steel more durable and bring markets nearer and that good roads increase property valnes values values val val- ues nes out of all proportion to the cost r Good Roads Are N Necessary to Efficient Operation of Automobiles of good roads to any anyone one individual Therefore the farmer Is now back of pf 1 road improvement Does the city man feel any interest In good roads Ask your our neighbor If he doesn't own an automobile he be expects expects ex ex- peets to own one and he be knows all about where the good roads are and what they mean But when his Influence influence influence ence counts big the greatest impetus has naturally sprung from the numerous numerous numerous numer numer- ous army of motorcar owners to whom motorcar ownership has made the territory territory territory ter ter- ter- ter for miles mUes around his neighbor neIghbor- hood Counties and states where good roads have bave become a steady part of a progressive program of ot legislation have seen values shoot up In the most surprising surprising sur sur- fashion and this again has bas brought home bome the fact that good roads pay vay for themselves Thus It Is natural natu natu- natural ral that the years 1919 and 1920 1020 will wUl see the most stupendous good roads programs programs programs pro pro- grams Inaugurated in America that the world has ever

fair consideration will be assured In 1 legislative charges against traffic since an accurate measure of impact damage will be pos pos- sible The experiments will cover a wide range taking Into account four tour factors fac fac- those tors-those tors those of speed height of fall type of tire used and the weight of the tho transportation unit Under the last heading It will be necessary for tor the bureau to consider distribution of weight above and under under under un un- I der springs and on back and front axles a quantity which Is decidedly variable on different makes of at motor and horse drawn vehicles The bureau has called upon the national automo automobile automobile bile bUe chamber of commerce to assist In the collection of ot this data much of which has not been generally tabulated tabulated tabulated tabu tabu- and a questionnaire has been sent to all motor truck track manufacturers of America on this subject Immediate Immediate Immedi Immedi- ate attention to this

deformation of one half by one half Inch copper cylinders cylinders' placed under a steel plunger subjected to the impact of traffic A varying height of ot fall is arrived at by different take takeoffs for Cor the machine First experiments indicated a wide range In the force of impact as between units with solid soUd I tires and pneumatics Working from these first steps the bureau officials plan to perfect a machine machine machine ma ma- chine which will take Into account the factors mentioned and which will enable enable enable en en- able them to provide a constant successIon
