NOMENCLATURE OF DIVISIONS OF AREA IN WORK- 

 ING PLANS. 



By Barrington Moors. 



There has been Httle time for the consideration of working 

 plans in America. Not only educating men for the profession, 

 so new in this country, and bringing the public to an apprecia- 

 tion of the aims of the profession, but also the gathering of 

 fundamental data on which to build the practice of the profes- 

 sion have absorbed the efforts of fortesters. Progress has, how- 

 ever, been astonishingly rapid, and we are now in a position to 

 begin to apply this education and accumulated data to the man- 

 agement of our forests. 



An article dealing very generally with working plans was con- 

 tributed by the author to the last number of the Proceedings of 

 the Society of American Foresters (Vol. VI, No. 2). Much 

 space was spent discussing the necessity of dividing the area 

 into working circles and of making separate working plans for 

 separate forests and parts of forests ; it was therefore impos- 

 sible, in necessarily narrowed limits, to give as much space as 

 desired to a clear cut definition of the basis of each division of 

 the area required in working plans. 



The first point to settle is the scientific designation of the 

 divisions to be made ; the second and most important, to deter- 

 mine the fundamental principles on which the divisions shall be 

 based. 



In the following definitions the term "working circle" will be 

 used to designate any area from which it is possible to obtain a 

 sustained yield. Although there has been some discussion as 

 to the advisability of the term, it has been commonly accepted 

 and is generally used by the English, the only people speaking 

 our language and practising forestry ; for it conveys the proper 

 meaning clearly and concisely, the word "working" implying a 

 utilization and development of the forest, and the word "circle" 

 conveying the idea that the working is done according to a "ro- 

 tation" or "cycle of years" which will bring you back to the same 

 starting point and thereby insure an indefinite use of the forest
