ROAD MILEAGE. 



The total mileage of public roads at the close of the year 1914 

 amounted to 17,995, of which 2,830.47 miles, or 15.73 percent, were 

 surfaced. Of the surfaced roads 829.16 miles were plain macadam, 

 42.80 bituminous macadam, 362.77 shell, 1,163 sand-clay, 256.24 

 brick, 42.5 gravel, 12 concrete, and 122 other materials, principally 

 sand-asphalt. The State has 3,686 miles of graded and drained 

 earth roads. 



In mileage of surfaced roads, Marion County stands first, with 200 

 miles, or 22.22 per cent; Gadsden County second, with 185 miles, or 

 46,25 per cent; Palm Beach County third, with 160 miles, or 44.44 

 per cent; Orange County fourth, with 157 miles, or 48.3 per cent; Lake 

 Coimty fifth, with 150 miles, or 46.15 per cent; and Duval County 

 sixth, with 144 miles, or 56.47 per cent. Six other counties have more 

 than 100 miles surfaced and 10 counties report none. 



In 1909 the surfaced roads amounted to 1,752 miles, or 9.97 percent, 

 of the total, thus showing that during the 5-year period 1,078 miles 

 were surfaced. 



The mileage statistics for the various counties are shown in Table 40. 



GEORGIA.! 



By S. W. McCallie, State Geologist. 



Georgia has a land area of 58,725 square miles, a total road mileage 

 of 80,669, and a population, according to the 1910 census, of 2,609,121. 

 The State therefore has a population of 44.42 per square mile of 

 area and 32.34 per mile of road, with 1.37 miles of road per square 

 mile of area. Of the population in 1910, 79.4 per cent, or 2,070,471, 

 was rural, thus indicating a rural population of 25.66 per mile of 

 road. 



The surface configurations of Georgia vary from a low, level, almost 

 featureless plain only a few feet above sea level to high rugged 

 mountains attaining an altitude of more than 4,000 feet. The State 

 is naturally divided into five physiographic divisions : The Coastal 

 Plain, the Piedmont Plateau, the Appalachian Mountains, the Appa- 

 lachian Valley and the Cumberland Plateau. 



The board of county commissioners, in counties where such boards 

 have been created, or the commissioners of roads and revenues, or 

 the ordinary of each county, has jurisdiction over the roads therein. 

 These officials, in many cases, appoint tliree district road commis- 

 sioners for each road district in the county and the district road 

 commissioners appoint one or more road overseers for their respec- 



1 The information contained in the tables [see Appendix] concerning the public roads of Georgia was 

 collected by the State geological survey, in cooperation with the United States Office of Public Roads 

 and Rural Engineering, largely by correspondence, but in some instances personal visits were necessary. 

 The work was begun about the 1st of March, 1915, and completed in December, 1915.
