WHAT IT COSTS TO CLEAN UP A FOREST 



The folloiving interesting statements regarding the results of experiments in piling and 

 burning the debris of logging operations on the Laurentide Company's limits, tvas presented at 

 the Montreal Forestry Convention by Robert W . Lyons, B.Sc.F. 



The following was carried out while making 

 experimental cuttings in a balsam-spruce type, 

 balsam forming 64 per cent of the stand. This 

 area was cut over for white pme some years 

 ago. Strips from one chain wide to three 

 chains wide and fifty chains long were cut 

 clean, and all logs were taken down to three 

 inches top diameter. The slash on each alter- 

 nate cut strip was burned. 



Therefore, as a safe and economical method 

 to dispose of slash, piling and burning as log- 

 ging progresses, was employed as a practical 

 remedy. The object was to burn the brush 

 prior to the removal of logs. The plan followed 

 promised to be feasible. It is, in brief, work- 

 ing two cutting crews together with two ad- 

 ditional men for burning the brush. These men 

 take the branches as they are cut and place them 

 on the fire. These fires were usually placed to 

 save reproduction and in a place suitable to the 



felling. The cutting crews were instructed to 

 bunch the tops close to the fires, a 20-foot radius 

 being the limit. If the branches should be wet, 

 or after a fall of snow, the fire was usually 

 started before the work commenced for the day. 

 It took from three to five minutes to make, and 

 two minutes more elapsed before branches 

 could be thrown upon it steadily. However, if 

 the branches were dry, the custom was to pile 

 the debris into round compact piles, all the large 

 ends lying in one direction, set fire to it and 

 then continue piling on the slash. This re- 

 lieved the men from facing a hot fire while the 

 branches close to it were being piled. These 

 piles could be started by the smallest blaze, 

 and in a country of white birch, the time spent 

 in making fires was practically eliminated. 

 Therefore, thirty to forty minutes were saved 

 daily. It might be noted, also, that in piling the
