108 FORESTRY IN GREAT BRITAIN AND IRELAND.

 drawing the graph is obtained by calculating also the values for 

 intermediate half per cents. 



16. Establishment of a Forest Fund. 



The Sub-Committee estimated that a sum of £3,425,000 will be 

 required to meet the expenses of the first 10 years. This amount 

 should be paid into a Forestry Fund, upon which the Forest 

 Authority would draw according to requirements, subject to 

 Parliamentary control. As this estimate was based upon pre-war 

 prices, the above-mentioned sum will not suffice to carry out the 

 proposed scheme ; it will have to be contracted unless additional 

 credits are sanctioned. 



The cost of the whole scheme was estimated to amount to 

 £15,000,000 at pre-war prices, spread over 40 years, when the 

 Department would become self-supporting. That sum is equal 

 to about one-fifth of the extra cost of the timber required during 

 the war. 



17. The Forest Authority. 



At first sight it might be considered that Agriculture and 

 Forestry should be administered by the same authority, as they 

 are on an ordinary estate. In such cases, a certain part of the 

 area is kept under wood, with the primary object of providing the 

 necessary amount of forest produce for the estate, any surplus 

 being disposed of. Such a combination has the further advantage 

 that, as already indicated, the same labourers can be employed 

 throughout the year, from spring to autumn on field work and 

 during the winter on forest work. At the same time there are 

 great differences between the two methods of soil utilization, 

 which have been explained in the early part of this book. The 

 chief difference lies in the fact that, while in agriculture, the crops 

 mature within 1 or 2 years, in forestry sowing and harvesting are 

 separated by a long series of years, which may amount to 100 

 years and more. Hence, the forester must elaborate plans for 

 the management of the woods for long periods of time. In the 

 case of a large scheme, hke that here under consideration, many 

 practical difficulties present themselves. If there were one 

 agricultural department in the United Kingdom, it might have
