forest. For this purpose, the coppice ^Yith standard system 

 is continued for a time, but as little as possible overwood cut, 

 and as many poles as possible are left standing, until the area 

 is fully stocked with overwood. The poles thus left should, 

 if possible, be seedling trees and not stool shoots. Another 

 method is, to grow the high forest direct out of the underwood, 

 provided the latter contains a sufficient number of seedling 

 trees, and has not suffered by too much cover overhead. In 

 either case, a good deal of planting may be necessary-. 



To prevent a great unevenness of returns during the first 

 rotation, the conversion will be effected only gradually, as 

 indicated under a. 



Example. — If the future rotation of the high forest be 120 

 years, the work would be distributed as follows : — 



Duriiui Period I., of, say, 40 years. — Convert one-third of 

 the area, cut very sparingly in the second part of the area. 

 Cut as usual in the third part. 



Diiriiiy Period II., of -iO years. — Convert the second part, 

 cut sparingly in the third part. Thinnings will be commenced 

 in the first part. 



During Period III., of 40 years. — Convert the third part. 

 Thinnings in the first part will be in full swing. Thinnings 

 will be commenced in the second part. 



r. Conversion of a Forest of Broad-Jenrcd Sperios into a Forest of 

 Conifers. 



An irregularly stocked forest of broad-leaved species, partly 

 coppice and partly coppice with standards, shall be converted 

 into a coniferous forest, a conversion which is indicated liy 

 the special conditions of the locality. 



The first and most important step is, to divide the forest into 

 a suitable number of compartments, by laying out a system 

 of roads and rides suitable to the locality. These compart- 

 ments are then grouped into a suitable number of cutting 

 series, without taking into consideration the present conditions 

 of the several woods, but merely future requirements.
