28 Forest Management 



PARAGRAPH XXV. 



PINCHOT METHOD. 



The published working plans for which Mr. Gifford Pinchot is re- 

 sponsible as author or as forester of the U. S. Forest Service, are, 

 notably, the following: 



The Adirondack spruce, published by the Critic Co., New York; 



A Forest Working Plan for Township 40, Bulletin 30; Bureau of 

 Forestry; 



A Working Plan for , Arkansas, 'Bulletin 32; Bureau of 



Forestry; 



A Working Plan for , South Carolina. Bulletin 56; Bu- 

 reau of Forestry; 



A Working Plan for , Alabama, Bulletin 68; Forest 



Service. 



These publications fail to be working plans in the proper sense of 

 the word. This failure 'might be due to the educational character of 

 the publications. Whilst they define the term "working plan" as 

 "simply a scheme of management for a forest tract," the reader looks 

 in vain for an actual "scheme of management." Forest utilization, 

 which commands the lion's share of forestal activity, is not considered 

 by the scheme of forestal management. 



The Pinchot method is classed as an increment method because it 

 lays all stress on yield forecasts. Future yields are forecasted on the 

 basis of a first cut, reaching down to a stated diameter limit, for periods 

 covering from ten to fifty years. 



Continuity of action is not advised in any case. Forestry as an in- 

 vestment is considered in bulletin No. 32 and No. 68. Table No. 15 in 

 bulletin No. 32, however, showing the interest on the assets left by 

 lumbering in virgin woods and depending as to their size on the sever- 

 ity of such lumbering, is incorrect. 



After the Bureau, a working plan should contain: 



1. A statement of facts. 



2. A statement of yield capacity. 



3. A statement of market and transport conditions. 



4. A systematic plan for lumbering. 



Only one-half page of bulletin No. 32, comprising 48 pages, is de- 

 voted to point 3, and only two pages to point 4. 



The chief rules of management are in all working plans: 



1. A fixed stump diameter limit. 



2. A fixed height permissible for stumps. 



3. Recommendations to prevent fire. 



4. Recommendations to prevent damage to young growth. 



Bulletin No. 68, published in 1905, excels in clear financial consider- 

 ations of the merits of a second growth, judged according to diameter 

 limits observed in cutting.
