LOGGING 
SLED ROADS 
Yarding Sled Roads. — Roads for yarding sleds are laid out by 
the camp foreman. Several main roads diverge from the skid- 
ways generally going up the slopes and, from these, branch 
roads are built directly to the logs. 
Main roads are built 5 or 6 feet wide, stumps are cut level with 
the grade and all brush, fallen timber and boulders cleared away. 
The road is roughly graded, holes and depressions are filled with 
brush or dirt, streams are spanned with crib bridges, swamps are

corduroyed and, if necessary, cross-skids are placed across the 
road at intervals of from 10 to 20 feet to prevent the runners from 
cutting up the road. Side-skids also may be placed along the 
lower side of the road to prevent the sleds from leaving it. On 
side slopes, the outer edge of the road may be built up by laying 
skids parallel to the road and then placing short skids, 2 or 3 
feet apart across them. This crowds the sled towards the bank. 
Main yarding roads are built by a special road crew. The 
secondary roads are laid out and constructed by the swampers 
while preparing the logs for skidding. Easy grades are de- 
sirable both for main and secondary roads, but are not essential
