Following are the notes on a few of the stubs burned : 



Yellow birch stub. 15 feet high. 30 inches d. b. h. 



Plenty dry punk at base. Bark covered with worm-eaten fungi. 



Dec. 10, p. m. Lighted in punk wood near ground. 



Dec. II, a. m. Whole inside had burned out and two-thirds of shell had 



fallen over into the snow and was still smoking. 

 Hard maple stub. 40 feet high. 17 inches d. b. h. 



Bark intact except for woodpecker holes. Covered with fungi. 



Dec. II, a. m. Lighted in woodpecker hole. 



Dec. 12, p. m. No signs of fire left. Cleaned off bark for a three-foot strip 



and lighted at the lower end. Two hours later had burned over all the 



cleared area and was still smoking. 

 Dec. 29, p. m. Had burned to the ground. 

 Hard maple tree. 17 inches d. b. h. 

 Hollow, open at butt. 

 Dec. II, p. m. Lighted dry, but snow covered punk inside. Was smoking 



slightly twenty minutes later. 

 Dec. 13, a. m. Had burned only dry punk or one-third area of cavity. 



Beech stub. 20 feet high. 14 inches d. b. h. 



Bark loose and two-thirds shelled off. Sap wood decayed but still firm. 



Center hollow. Several knot holes rotted through to center. 

 Dec. 13, p. m. Lighted in one of lower knot holes. An hour later whole 



inside of stub was a solid blaze coming out of the upper knot holes. 

 Dec. 29. Had burned to the ground. 



Hard maple stub. 25 feet high. 12 inches d. b. h. 



Bark tight except at top. Several short seams and limb scars open into 



hollow center. 

 Dec. 13, p. m. Put extra dose of gas into limb scar 4 feet above ground. 



An hour later whole inside of stub was burning. 

 Dec. 29, p. m. Had burned to ground. 



While there are many stubs which cannot even be lighted, and others 

 which will only partly burn, the method may be worth while in con- 

 junction with other methods. 



Industrial Usi; of Wood Fuel 



When the wood-fuel campaign was first inaugurated, it was expected 

 that the greatest increase in the use of wood would be practically re- 

 stricted to the country, namely, the farms and small villages where 

 wood could be conveniently hauled. Owing, however, to the acute 

 shortage of coal, necessity forced a number of industries and factories 

 to turn to wood for fuel which would not otherwise have considered it 

 on account of the greater expense and less convenience of handling.
