 varies from 8 to 15 cents per thousand feet. 



TOTAL COST OF LOGGING AT ONE OPERATION. 



The following deals with the cost of logging at a rather large 

 operation in the Pacific Northwest during 1910, 1911, 1912, and 1913. 

 Unless otherwise noted the discussion following the tables applies to 

 1912. It is impossible to discuss all the costs given. For the most 

 part, the classifications are those of the operator. 



CHARACTER OF COUNTRY. 



Part of the area logged during 1912 is shown in figure 20. The 

 country is mountainous, rough, and badly broken. The slopes in 

 general are steep. No rock outcrops or cliffs were encountered. 

 The streams are not of drivable size, but are so located as to make 

 it unnecessary to pump water for long distances. 



SOIL. 



The soil is sandy loam with a clay subsoil. It drains poorly, 

 making it necessary to gravel-ballast all spur railroads used for a 

 year, also those used during the wet season. Practically all the bal- 

 last was hauled 3 miles. 



OUTPUT. 



The output for 1912 was as follows :
