of increased traffic and heavier rolling stock. Prices, as outlined above, 

 have also steadily risen. 



For a long time all standard gauge railroad ties were 8 ft. in length. 

 In recent years many railroads have increased this to 8^ ft. and some 

 even to 9 ft. Formerly a thickness of 6 in. was prescribed for both sawed 

 or hewed ties, but now many of the railroads require a thickness of 6| to 

 7 in. Pole ties, that is, those faced, either by hewing or sawing on two 

 parallel sides, are now usually required to measure 7 to 8 in. on the 

 face. Squared ties, or those hewed or sawed on all four sides, are now 

 customarily 7 by 9 in. in cross-section, although some railroads still hold 

 to the dimensions of 6 by 8 in., which were commonly in use a few years 

 ago.

 by some of both the larger and smaller railway systems in the country,
