WORKING PLANS 215 



order that there may be no danger of windfall, each series 

 should be separated from the next by a -broad ride, as the 

 ride-side trees then become storm-firm and are not so easily 

 blown down when the wood lying to the windward is cut. 

 If the woods happen to be in several isolated blocks, each 

 may form a separate series, or two or more small blocks may 

 be included in one series. 



After deciding upon the working circles and felling series 

 the compiler lays down the felling prescriptions, which will 

 follow the sylvicultural method of treatment adopted. There 

 may also be special prescriptions not directly following the 

 lines of a well-known method of treatment, and such would 

 be given in full detail. In locating the annual felling 

 areas the compiler takes into consideration the direction in 

 which the felling should proceed. This is usually from the 

 north-east or east of each block towards the south-west or 

 west, as this is in the opposite direction to the prevailing 

 winds. By proceeding thus, danger from windfall is reduced 

 and young plantations are formed behind the shelter of 

 standing woods. Directly following the felling prescriptions 

 come the instructions for sowing and planting. The yield 

 will be estimated from such data as are available, and into 

 this matter will come questions of possibility by area, possibility 

 by volume, possibility by number of stems, and so on, which 

 are connected with the method of treatment adopted. With- 

 out going into this subject it will be sufficient to say that the 

 compiler of the plan must arrange that the yield is so checked 

 that excessive felling is impossible, while insufficient cutting is 

 avoided, for this too would be an error. 



The supplementary provisions are instructions concerning 

 roads, buildings, staff, or any such matter. Finally, it is 

 desirable to form an estimate of the future revenue and 

 expenditure.
