LOGGING IN THE DOUGLAS FIR REGION", 95 



two and one-half hours for the starts and stops to straighten the 

 logs out in the roads ; two and one-half hours hauling the main line 

 in and out. Average ground conditions were assumed. 



It is obvious that estimates made in this way are artificial and of 

 questionable value. Yarding records can be found which indicate 

 that the above estimates are in error. In fact, the man who made 

 this estimate has since exceeded it in small timber. 



Without doubt, experience of the right character is the best basis 

 for estimating the yarding output with specific conditions. One can 

 acquire a satisfactory basis for estimating yarding output through 

 observation, including a careful examination of the different factors 

 of each chance, together with an analysis of output records. In the 

 following discussion of the labor cost, a body of such records is given, 

 with the factors in the case stated as fully and accurately as possible. 



Labor cost. — As a rule it is the labor cost only that is given under 

 the heading " Yarding cost " in the logging cost statements of opera- 

 tors, for the labor constitutes the bulk of the yarding cost, though 

 by no means all of it. Cost is largely determined by output, but 

 the size of the crew and the wages paid also count. 



Statements giving the average labor cost per thousand feet, be- 

 cause they vary so much and because it is so difficult to relate average 

 costs to practical assumptions, are of little value. The following 

 statements may afford some clew to this cost, but should not be taken 

 too seriously:

Average logs : 



2.000 feet per log $0. 44

The number of men in a yarding <5rew is more or less fixed, but if 

 can not be said that there is a standard crew. Foremen have differ- 

 ent ideas of the proper size of a crew, and the members of the amount 

 of work they should do. In addition, the size of the crew varies to
