CROSSTIES PURCHASED AND TREATED IN 1915. 



ern pine furnished the greater part of these, although Douglas fir and 

 cedar were reported in large quantities. 



The number of ties purchased by the electric railways and light, 

 heat, and power companies amounted to 8.87 per cent of the total, a 

 decrease of 281,000 ties in comparison with the number purchased 

 by these companies in 1911. The greater part of those reported were 

 white oak, cedar, and chestnut. Southern pine and reel-oak ties were 

 purchased in nearly the same quantities, while fewer birch ties than 

 any other were separately reported.

Table 3 shows the number of crossties reported purchased by the 

 steam railroads, representing 78.46 per cent of the total mileage of 

 the country, classified by regions which are the same as those used 

 by the Interstate Commerce Commission. 



The eastern region comprises that portion of the United States 

 bounded on the west by the northern and western shores of Lake 

 Michigan to Chicago, thence by a line to Peoria, thence to East St. 

 Louis, and down the Mississippi River to the mouth of the Ohio 

 River. It is bounded on the south by the Ohio River from its 

 mouth to Parkersburg, W. Va. ; thence down the Potomac River to 

 its mouth. , This region is second in size of the three regions and has 

 a total of 64,491 miles of railroad. The actual mileage of the report- 

 ing railroads is 43,018 miles, or 66 per cent of the total mileage of the 

 region. 



The southern region is that portion of the United States bounded 

 on the north by the eastern region and on the west by the Mississippi 

 River. It is the smallest of the three regions and has a total of
