AFFORESTATION OF WATERWORKS CATCHMENT AREAS. 231 



the successful working of forests frooa a financial point of view 

 can be greatly assisted. Saw-mills and wood-working machinery, 

 driven directly by water-power or by electric motors, may 

 contribute to the profitable utilisation of trees in several ways, 

 and particularly by reducing timber to marketable sizes, and by 

 providing mechanical power to produce various kinds of wooden 

 implements and articles of commerce, also by providing power for 

 making wood-pulp. With regard to the question of cost, the 

 actual average expenditure incurred by the Corporation during 

 the last five years has been .£261 per annum. This year, includ- 

 ing the extended plantinsj operations already arranged for, the 

 expenditure will be higher. After observing the results of recent 

 operations around Lake Vyrnwy, and examining the details of 

 expenditure, I feel satisfied that for the class of lands to which I 

 particularly refer, afibrestation on the catchment areas of water- 

 works can be carried out not only with great advantage to the 

 country, but also with profit to the owners of the works.
