FOREST COMMISSIONERS REPORT. 79 



between the bases of the branches in the whorl. Later in the 

 season the leaves on the tip become brown, and the leader dies. 

 When the weevil appears in the stand the top of the tree should 

 be cut off and burned, to prevent its spreading to others. A 

 side branch will then grow around and take the place of the 

 leader. Frequent inspection and prompt action will sometimes 

 save several years in the growth of the stand, while it may be 

 that no trouble of this sort will be experienced at all. 



Logging: — Ground free of slush, dense, weedy growth, and 

 dead or decaying trees will give little opportunity for insects and 

 fungi to breed. Consequently it is not advisable to plant too 

 soon after logging. Little fear may be had of the subsequent 

 health of the young trees when they are put in a clean piece of 

 ground. 



Thhiu'nig: — Unless the trees crowd badly no thinning should 

 be made until the stand is from 20-30 years of age. At this 

 time the poorer trees, those that have become overtopped, and 

 enough of the others to leave good air space around each of the 

 crowns of the trees left, should be removed. This material 

 should be of boxboard size, and bring a fair price. The remain- 

 ing stand should thenceforth accelerate in growth, particularly 

 in diameter, the stand as a whole, in final cut and thinnings, 

 having yielded a maximum cut per acre.
