200 FORESTS, WOODS, AND TREES 
anticipated, as both Ogden and Mixenden reservoirs, though 
situated at nearly 1000 feet elevation, lie in well-sheltered 
valleys. I have not been able to obtain any report on 
these plantations, as, for some reason or another, little 
interest has been taken in afforestation by the Halifax 
Corporation. No forester is employed. See Trans. Roy. 
Scot. Arbor. Soc. xvii. pp. 86-92 (1904), for reports on 
the afforestation of the Halifax areas. 
Todmorden obtains its water supply from Gorpley Clough 
reservoir, with a gathering ground on Inchfield Moor of 
690 acres, between 845 and 1500 feet elevation. The 
whole area, of which about 600 acres are owned by the 
Corporation, is hill pasture and moor, without any planta- 
tions or arable land, and free from farmsteads or habitations, 
except the waterman’s house. The water is filtered, and no 
other precautions are considered necessary. See TZvrans. 
Liverpool Engineering Soc. xxix. (1908). 
Morley obtains its water supply in part from Withens 
reservoir in Cragg Vale, Mytholmroyd, with a gathering 
ground of 1200 acres, between 900 and 1000 feet elevation, 
all hill pasture and moorland; and no part of it is owned 
by the Corporation. The area is without habitations or 
farmsteads, except a gamekeeper’s lodge, uninhabited at 
present. The water is filtered, and no other precautions 
are considered necessary. 
Wakefield obtains its water supply from a gathering 
ground of 2737 acres, between 1000 and 1530 feet 
elevation, with two reservoirs, Green Withers at Rishworth, 
and Ringstone at Barkisland. The Ardsley reservoir, also 
used for storage, is not on the catchment area. The 
Corporation have power to utilise a further area of 600 
acres, all moorland and lying between 900 and 1200 feet, 
and to construct thereon three additional (Oxyegrains, 
Upper and Lower Booth Dean) reservoirs. The gathering 
ground of 2737 acres to the existing works, is all moorland, 
with the exception of about 250 acres of rough grass; and 
most of it is covered with peat varying in depth from one
