i Decrease in surfaced mileage reported does not mean retrogression, but is accounted for by higher 
standard requirements and greater accuracy of reports in 1914 as compared with previous reports. 
The relation of total mileage and surfaced mileage to area and rural population in 
Central, Pacific, and Mountain States, for the years 1904, 1909, and 1914, is presented 
in Table 5.
