FIKST Booiv OF FORESTRY 



Where the wood i.s still in the ordinary irregular mixture 

 of old and young trees the larger trees on the western 

 half of each parcel would grow old and produce too little 

 wood before the time for cutting, and it is better to take 

 out the oldest timber all over the parcel from time to time 

 whenever convenient, independently of the regular cut- 

 ting on the strips. If it is desirable to cut a])out the same 

 amount of thnber ever}' year, as. for instance, where a pul]) 

 mill or sawmill is dependent on such regular supply, it is 

 necessary with this, as with all methods, that the yearly cut 

 should not be greater than the yearly growth. In woods 

 where too much timber is young sapling stuff the cut must 

 at first be kept proportionately below the normal amount. 

 Just what this cut should be can only be found by making 

 such a survey as was indicated in the previous chapter. 



What this growth should be can be learned from the 

 following table :
