132 THE MANAGEMENT OF WOODLANDS. 



Classes in the various working-circles, and to prepare a sketch 

 Felling-plan according to area (see pp. 129, 135), then to fix 

 the extent and allocate the position of the Annual Falls, and 

 finally, to elaborate the Working-plan and prepare the Explan- 

 atory Note and the Stock Map which should accompany it. 



To find the distribution of the different age-classes the crops 

 in each working-circle are registered according to age in 20-year 

 periods, when it can easily be seen how far each age-class varies 

 from the normal proportionate area it should have ; and it will 

 be found useful to prepare at this same time a Stock Map 

 showing the woodland area, its division into compartments, 

 and the different kinds of crops and their respective periodic 

 age-classes in each working - circle, giving to the youngest 

 period (under 20 years) a light wash of any chosen colour, to 

 the 21- to 40-year-old class a darker wash of the same colour, 

 and so on for the older periodic age-classes. And if there are 

 different working-circles (e.g., for broad-leaved trees and for 

 Conifers), different colours must be used for each working-circle. 

 Woods under natural regeneration (e.g., Beech, Silver Fir, Scots 

 Pine) can be indicated by being given the palest wash and then 

 having lines of darkest wash drawn across the ground colouring, 

 thus indicating a combination of the youngest and the oldest 

 age-classes until the mature seed-bearing trees are removed. 



The Felling-plan according to area is first of all roughly 

 sketched by allotting areas to the various periods according to 

 their age, as shown in the register, so as to see how a convenient 

 felling-series can be made, and also, with the assistance of the 

 Stock Map, to note where severances may require to be made 

 now, if necessary at all, in order to protect woods that may 

 have to be exposed to winds later on. An important matter 

 is to try and arrange the felling-series (of which there may be 

 one or more, according to circumstances) in the direction likely 

 to afford the greatest protection from wind ; and it is also 

 desirable to make intermittent felling-series in place of any
