Show Could Macadamize Miles of Highway at Small Expense The macadam paving of Second avenue ave-nue batweao Canyon road aad V irginia treat ia Bait lake City, ooat tha mtinieipaHtjr 66 eeaU a yard. This .-out iacludea the rolling of ike roadbed and tbe application ot tka material in a workmanlike manner, tha roadway )aiing tkc inspection of tha public worka department of the city. A macadam roadway sixteen feet in width, cob vexed ao that all water would drain to tka edge, leaving the roadway paabla regardless of tka heavy rain of spring, and the disintegrating effects of melting anow, could be constructed, at that proportion, for Mlul.33 par mile. With a bond iaaae of 1.000,000, such aa ia proposed by good -roads enthusiasts enthusi-asts for this oounty, tka eounty could secure an aggregate of 163.8 miles of suck road, provided the roada were built to speeificatioa and full return given the eounty for every dollar expended. ex-pended. This estimate is based on the theory that tha natural skala that is found in abundance in all tka canyons and hill .wies nt the county was used. Tkere are many miles of roadway that could he constructed where it would be un necessary to haul this shale more than one mile to tha point it would be used. If the macadam were of the ebarae ter used on Second avenue, an ideal driveway could be constructed at moderate mod-erate cost. To make snch a road a success, however, it would be necessary to roll tka natural roadway propern apply the coarse base and roll it thoroughly, thor-oughly, aad then apply tha surface material of medium shale or coarse screenings and roll that thoroughly. These various steps must be followed or all tha labor is lost, as the material, unless bound together by heavy rolling, would disintegrate quickly la eanyoo drives, rock crushers could be established close to the roadways, road-ways, tkus reducing tke haulage cost of materials to a minimum. A liberal estimate for coat of macadam mac-adam roada, with one mile aa a maximum maxi-mum haul for material, is 75 cents a yard. At that rata a permanent ri could be built for $7040 tha mila. nt' kill asd down, following the natural grades now in use. This estimate would permit the reduction of the steeper grades to such a degree that labor ot teams would not be needlessly ax-ponded. ax-ponded. One of the beauties of a natural country road in a slightly hilly country coun-try is its rise and fall aad its broad and beautiful sweepe and eurvee. In tke construction of country drives it would be desirable to leave these gentle gen-tle grades aad long, beautiful curves that add so much to the beauty of the drives. By following the original Haas of these roads as they now exist, tke beauty of tka drives would be en nanrsd a thousandfold more than it' tkay were reduced to straight lines aad all curves eliminated. Teamsters of experience say tkat team kauling on dead level roads tire earlier aad show tha strain quicker tkao the same teams tkat poll their loada over slightly rolling roads, which alternate tha upgrades with descents. The horses must get up la tka collar oa tha uphill pulls, but ars given a chance to relax on tha downhill palls. They must hold back on tka dowa-gradee, dowa-gradee, and this gives their shoulders a rest from tke collars, wklek cool aad maks it easier for tka next uphill pull. Boise countv.
