280 COMPOUND COPSES UNDER CONVERSION. 



First Case. 



Let us suppose that it is desired to convert into high forest a 

 wood of small extent, consisting of a simple Working Circle of com- 

 pound copse, and divided into 30 coupes of equal extent stocked 

 respectively with crops from one to thirty years old. Let us also 

 suppose that this wood offers all the resources necessary to enable 

 conversion operations to be started forthwith. 



An examination of the standing stock has shovsrn (i) that the six 

 coupes cropped with underwood from 25 to 30 years old contain a 

 very numerous reserve, which forms a leaf-canopy equal to that of a 

 Close Primary Felling, the underwood being in consequence thin, 

 sickly and sparse, (ii) that the stock in the latter coupes contains 

 fewer standards, but consists of a flourishing underwood, in which 

 the more valuable species are well represented, and (iii) that the 

 exploitability of the forest under a seed-grown crop would require a 

 Rotation of 150 years. 



This Rotation being divided into 5 Periods of 30 years each, 

 we will suppose that the General Working Scheme has been drawn 

 up thus : — 



First Block Coupes aged from 30 to 25 years. 



Second Block do. do. 18 to 13 „ 



Third „ do. do. 12 to 7 „ 



Fourth „ do. do. 6 to 1 



Fifth „ do. do. 24 to 19 '^, 



The Special Scheme of Exploitations for each Period would 

 then be broadly thus ; — 



First Block Regeneration Fellings. 



Second Block Thinnings or Preparatory Cuttings. 



Third, Fourth and Fifth \ Compound Coppice Fellings, over 



l one-thirtieth of the aggregate area 

 Blocks united J every year. 



Second Period. 



First Block Cleanings and First Thinninorg 



Second Block Regeneration Felliugs. 



Third Block ,... Thinnings Preparatory to Conversion.
