 the healing process is going on. the exposed

 paint. This should be repeated as often as 

 necessary, until the wood his entirely healed. 

 When this is properly done, healed wounds are 

 difficult to detect.

decay as readily as do those caused by cutting 



off limbs in the wrong way. All loose or torn 



bark should be removed from such wounds, and 



the exposed wood given as smooth a surface as 



pos'-.ible; also, the sound bark surrounding 



the exposed wood should be cut so that it has 



a continuous smooth edge. The outline of the

bottom of the wound. Cutting the bark in this ^_ 



way allows the sap to flow freely around the 

 wound and thus easily nourish the new bark 

 that is forming. 



Water must not be permitted to gather in 

 the wound, under any circumstances, as it al- 

 ways hastens the decay of the remaining wood. 

 A small groove cut into the lower end of the 

 wound will allow the water to trickle away as 

 rapidly as it collects. To protect the exposed 

 surface better, it should be given a good coat of 

 white lead or other available paint. One coat 

 will not last all the years it takes for such a 

 wound to heal; the wound should be given a 

 new coat of paint whenever the previous one 

 is worn out. 



Properly treated, bark wounds will not ser- 

 iously endanger the life of a tree. Repairing 

 damages after the wood has had a chance to 

 decay deeply is a very different matter. The 

 same principle of removing all injured or de- 

 cayed wood and bark, and preparing the surface 

 to exclude water and to permit rapid growth 

 of new bark, applies to the advanced condition. 

 The photographs show bark wounds in various 

 stages of healing, also stubs of limbs which 

 were not cut off properly. 



The Laurentide Company is more than a 

 manufacturing concern. From the last copy of 

 Le Digesteur it is seen that they are encourag-

 of fresh air to houses by printing descriptive pic-

 housewives. More than forty are enrolled. 



A SETTLER'S EXPERIENCE. 



New Books on Forestry. 



A settler named Olson and two others of the 

 Haileybury, Ont.. district, had a trying experi- 

 ence. They sent their women folk out when 

 the fire drew near. The Olson home was first 

 surrounded by the fire and the other two went 

 to help protect it. Olson got on the roof and 

 pulled up pails of water which the two below 

 carried to him. The nearer the fire got the 

 hotter it became. Finally the house was com- 

 pletely surrounded and the dense smoke made 

 it impossible for the trio to escape. It then 

 became a battle for their lives, and those de- 

 pended on their keeping the house from burn- 

 ing. It soon became so hot that the skin on 

 Olson's face as he sat on the roof begaji to 

 peel. He maintained his position by dumping 

 every second pail of water over his body. They
