counties that reported no surfaced roads. 
In 1909 Tennessee reported 5,353.5 miles, or 11.66 per cent of sur-

formation showing the total mileage and mileage of surfaced roads by

Texas has a land area of 262,398 square miles, a total road mile- 
age of 128,960 and a population, according to the 1910 census, of 
3,896,542. The State has a population of 14.8 per square mile of 
area and 30.21 per mile of road, with 0.49 mile of road per square 
mile of area. Of the population in 1910, 75.9 per cent, or 2,958,438,

road. 
1 The collection of road statistics was begun early in 1915 by Dr. William B. Phillips, collaborator for 
this Office, and director of the bureau of economic geology and technology of the University of Texas. 
Subsequently, however, Dr. Phillips resigned his position at the university to take up work in another 
State. Mr. J. A. Udden, of the university, was then appointed collaborator, and the work was continued 
by him. A cooperative arrangement was also made whereby the assistance of Prof. R. L. Morrison, of 
the Agricultural and Mechanical College of Texas, was secured. In addition, extensive correspondence 
was conducted directly with various county officials, commercial organizations, and good-roads associa- 
tions. Valuable assistance was rendered by Mr. D. E. Colp, secretary of the Texas Good Roads Association.
