is temporarily removed when the sled is turned around in the 

 woods. The upper bunk has grooves cut on the ends or on the 

 sides, and these grooves fit around the starts, which are mortised 

 in the lower bunk and fastened to the runners. 



Several logs with the forward ends supported on the bunk and 

 the rear ends dragging on the ground can be loaded on a yarding 

 sled.

 Fig. 35. — Methods of fastening Logs to the Bunk of a Yarding Sled. 



The equipment consists of two f-inch chains 18 or 20 feet long 

 which are used to fasten the logs to the bunk of the sled. Each 

 chain has a grab hook on one end and a bunk hook on the other. 

 The use of chains in binding logs is shown in Fig. 35. A third 

 chain is sometimes used to bind the rear end of the load. 



Two horses are used for hauling yarding sleds, except on 

 long hauls or unfavorable grades, when four may be employed. 



An average load is five large logs, or seven or eight small ones, 

 the total averaging from 700 to 1000 feet, log scale. Five thou- 

 sand feet is an average day's work for a team and sled on a haul 

 of ^-mile. The cost per thousand feet for teaming expense 

 under such conditions averages from 75 to 90 cents. 



In the Lake States and in the Adirondacks where yarding 

 sleds are not used, a "bob" performs similar work. It consists 

 of the front runners of a "two-sled," equipped with chains for
