(150 M per " 40 " or greater), slash will be so dense that considerable piling will be necessary before skidding can be done, and under these circumstances it would be much cheaper to burn at the time of cutting than to wait until spring. Figures from further operations also show that 25 cents is a fair average cost for burning of slash at time of logging, to say nothing of the increased benefit to skidding and to the operation as a whole.
In summarizing conditions generally, the policy has been adopted to enforce winter burning, or very early spring burning wherever winter burning would entail unreasonable expense.
Below are general instructions for disposing of various kinds of slash under different conditions:
CEDAR, AND TO A CERTAIN EXTENT, TAMARACK
Isolated or very small tracts.
Pile and burn in winter or early spring, a strip at least 150 feet wide along roads or any dangerous points. Pile and burn any slash that falls from the cedar swamp on to high land.
Where there is much small cedar or other timber remaining, pile slash well in at least a 150-foot strip around slashing, and burn strip in early spring.
Upland Cedar and Hardwoods.
On good agricultural soil with very little or no valuable timber remaining, fire line as in No. II, or let burn hard with general fire, but in early spring only.
Summer cutting of Cedar.
When it can safely be done, pile and burn a fire line along roads, rights-of-way, and settlements as cutting proceeds. Otherwise, slash to be disposed of as per Nos. I, II and III when dry season is over.
SPRUCE AND BALSAM
Where spruce alone is cut and the stand is mixed with pine or hard-woods, burn the slash as logging proceeds.
Where 40 to 50 per cent of the number of trees remain standing, fire-line a strip at least 150 feet wide around entire slashing by burning slash in winter or early spring. If clean cut, pile slash in windrows and burn in early spring.
Any Spruce or Balsam.
Where most of spruce or balsam is cut out, but where there is considerable timber remaining that may be valuable in the future, pile slash in windrows as logging proceeds and burn in early spring.
