From summaries which appear in the Sixteenth Statistical Report of the Interstate Commerce Commission, prepared by its statistician as the complete report for the year ending June 30, 1903, this information is obtained:

Mileage And Capitalization Of Roads

The total single-track railway mileage in the United States on June 30, 1903, was 207,977.22 miles, having increased 5,505.37 miles in the year ending on that date. This increase exceeds that of any previous year since 1890. The nineteen states and territories for which an increase in mileage exceeding 100 miles is shown are Arkansas, California, Georgia, Illinois, Louisiana, Michigan, Minnesota, Mississippi, Missouri, North Carolina, North Dakota, Pennsylvania, Texas, Washington, West Virginia, Wisconsin, Indian Territory, New Mexico, and Oklahoma. Most of the railway mileage of the country, excepting that of street lines, is covered by reports rendered to the Commission by the carriers.

For the year under consideration the operated mileage concerning which substantially complete returns were made was 205,313.54miles, including 5,902.87 miles of line on which trackage privileges were exercised. The aggregate length of railway mileage, including tracks of all kinds, was 283,821.52 miles, being classified as follows: Single track, 205,313.54 miles; second track, 14,681.03 miles; third track, 1.303.53 miles; fourth track, 963,36 miles; and yard track and sidings, 61,560.06 miles. Thus it appears that there was an increase of 9.626.16 miles in the aggregate length of all tracks, of which 3,339.13 miles, or 34.69 per cent, were due to the extension of yard track and sidings.

The number of railway corporations included in the report was 2,078. Of this number 1,036 maintained operating accounts, 805 being classed as independent operating roads and 231 as subsidiary roads. Of roads operated under lease or some other form of contract, 316 received a fixed money rental, 150 a contingent money rental, and 275 were operated under conditions not readily classified. In the course of the year railway companies owning 11.074.19 miles of line were reorganized, merged, consolidated, etc. For the year 1902 the corresponding item was 7,385.99 miles.

The length of mileage operated by receivers on June 30, 1903, was 1,-185.45 miles, showing a decrease of 289.87 miles as compared with the previous year. The number of roads in the hands of receivers was the same as at the close of the previous year, 9
