Maryland has a land area of 9,941 square miles, a total road mileage 

 of 16,458, and a population, according to the 1910 census, of 1,295,346. 

 The State, therefore, has a population of 130.3 per square mile of 

 area and 78.7 per mile of road, with 1.65 miles of road per square 

 mile of area. Of the population in 1910, 49.2 per cent, or 637,154, 

 was rural, thus indicating a rural population of 38.71 per mile of 

 road. 



By an act of the legislature of 1908, as amended, the State roads 

 commission was created and consists of the governor, ex officio, and 

 five members appointed by the governor. The chairman is desig- 

 nated by, the governor. The commission elects a secretary and 

 employs a chief engineer, assistant engineers, and other necessary 

 help. The commission must select, construct, improve, and main- 

 tain a general system of State roads in and through all of the counties 

 of the State. It is authorized, in carrying out its duties, to take over, 

 by purchase or condemnation, turnpikes forming a section of a main 

 road to be improved by it. The construction and improvement of 

 all State roads or parts thereof are required to be done under the 

 supervision and subject to the approval of the commission, and in 

 accordance with plans and specifications prepared by the chief 

 engineer and approved by the commission. Where the cost of any 

 work on a State road will exceed $500, it shall be let under contract 

 by the commission. 



The commission is authorized to contract with the board of com- 

 missioners of any county to grade, maintain, and repair, and to more 

 fully construct, the State roads within the borders of such county. 

 The commission is authorized to estabhsh stone-crushing plants, 

 located at such points as to secure most economical water or other 

 transportation, and to work State convicts in operating the same. 

 The use of State convicts in road and bridge construction and main- 

 tenance work is also authorized. The commission is empowered to 

 make such regulations and orders as it may deem necessary for the 

 preservation of State roads and to regulate the use of same by traction 

 engines and such other vehicles or conveyances as produce more than 

 ordinary wear thereon. 



The State road system, which includes State roads paid for entirely 

 by the State, State-aid roads paid for by the State and counties 

 jointly, and turnpikes purchased by the State, comprises 1,178.22
