two areas, totalling 2630 acres, is owned by the Board.

 in June 1918 by the Engineer to the Board. 



Darwen obtains its water supply from a gathering 

 ground of 660 acres of moorland and hill pasture on 

 Darwen Moors. The water is filtered. No particulars 

 were obtainable from the Town Clerk. The Journal of 

 Board of Agriculture, xi. 469 (1904), states that Darwen 

 owns 500 acres of gathering ground, between 700 and 

 1300 feet, nearly all hill pasture, with 12 acres of wood- 

 land.

Wigan obtains its water supply in part from two upland 

 surfaces — 2200 acres at Wrightington, between 218 and 

 400 feet elevation, and 500 acres at Billinge, between 316 

 and 428 feet elevation. Tlie gathering grounds, which 

 appear to be entirely agricultural land, are not owned by 

 the Corporation. " The farmsteads, etc., are drained and 

 the tanks emptied when required, the contents being carted 

 away and spread over suitable ground to prevent pollution." 

 The whole of these two areas appears to be suitable for 

 afiforestation, and, in any case, ought to be under the 

 complete control of the Corporation. 



Warrington obtains its domestic supply entirely from 

 wells, but it obtains water for trade purposes from a 

 gathering ground of 1360 acres, between 140 and 250 feet

 Corporation do not own any part of this area, over which 

 they have merely the right to collect the water.
