MAINE. 
By Lucius D. Barrows, Collaborator. 
Maine has a land area of 29,895 square miles, a total road mileage 
of 23,536.91, and a population, according to the 1910 census, of 
742,371. The State, therefore, has a population of 24.83 per square 
mile of area and 31.53 per mile of road, with 0.79 mile of road per 
square mile of area. Of the total population in 1910, 48.6 per cent, or 
360,928, was rural, an average of 15.33 per mile of road. 
The northeastern part of Maine, especially the eastern part of 
Aroostook County, is devoted almost entirely to farming. The 
western part of Aroostook County and the northern parts of Penob- 
scot, Piscataquis, Somerset, Franklin, and Oxford Counties are 
largely wild lands. In these sections lumbering is the principal 
industry, and there are very few roads. A great many summer 
resorts are located along the Atlantic coast line from Kittery to East- 
port, while many summer camps, sporting camps, and summer hotels 
are found along the rivers and on the inland lakes. Many people now 
come to Maine in the summer by automobile. This summer tourist 
travel and the great increase in the number of automobiles owned in 
the State, together with the need for good roads on the part of the 
farming districts, have given a great impetus to road building in 
Maine. 
The State has many rivers and streams, and the construction and 
maintenance of bridges is no small problem. From an investigation 
made in 1907, it was learned that there are more than 6,800 bridges 
in the State. Many of the larger bridges have been constructed 
under special legislative appropriations. 
State and State-aid highways and the maintenance of the same 
are under the direction of the State highway commission, consisting
