Detailed information regarding sources and amounts of revenues, 

 bonds issued and outstanding, total mileage of roads, mileage sur-

ALABAMA. 



Alabama has a land area of 51,279 square miles, a total road mile- 

 age of 55,446, and a population, according to the 1910 Census, of 

 2,138,093. The State has a population of 41.7 per square mile of 

 area and 38.56 per mile of road, with 1.08 miles of road per square 

 mile of area. Of the population in 1910, 82.7 per cent, or 1,767,662, 

 was rural, thus indicating a rural population of 31.9 per mile of road. 



In 1911 the legislature enacted a law creating a State highway 

 department, which is composed of a State highway commission and 

 a State highway engineer. The State highway commission consists 

 of a professor of civil engineering from the Alabama Polytechnic 

 Institute, the State geologist, and three other members appointed 

 by the governor. 



The State highway engineer is elected by the State highway com- 

 mission and holds office subject to the pleasure of the commission. 

 The State highway engineer, with the consent and advice of the 

 State highway commission, may employ such assistant engineers
