as pulpwood or tence posts or fuel wood, and the rapidly 

 growing, higher-earning timber may be reserved until it 

 approaches financial maturity — that point at which, under 

 existing market conditions, it will afford the best returns 

 to the owner. 



Southern Forest Experiment Station research in the 

 shortleaf-lobloUy pine type has demonstrated that under 

 selective cutting, in which only the more mature and the 

 defective trees are removed, higher grades of lumber and 

 considerably higher prices per M board feet cut are obtained 

 than when clear cutting is practiced. Lower logging and 

 milling costs per M board feet usually result. Selective 

 cutting in this type aims at better forestry but also at 



increased profits. Although definitive studies have not 

 been made in the hardwoods, it is believed that the selec- 

 tive system of cutting is also applicable to these forests. 

 In longleaf pine alone this system of tree selection does not 

 usually reproduce a longleaf pine forest. This species re- 

 quires full light and open stand conditions for successful 

 reproduction. Therefore, one or another of these systems 

 must be used: (1) clear cutting and planting, (2) clear cut- 

 ting with groups of seed trees, or (3) a group-selection sys- 

 tem in which small scattered areas are clear cut. The 

 successful use of any ol these systems depends upon the 

 protection of the reproduction from hogs.

 products in earners, wages, and value added by 

 manufacture is of considerable significance.
