236 FORESTS, WOODS, AND TREES 
west of the village of Pen y Cae, with a gathering ground 
of 1565 acres. I have not been able to obtain any 
particulars of this area, which appears to be all moorland 
and hill pasture. The water is filtered. 
Oswestry obtains its water supply from Penygwely 
reservoir, 54 miles distant and near Llansilin in Denbigh- 
shire, with a gathering ground of 455 acres, at 1100 to 
1467 feet elevation, consisting mainly of hill pasture and 
sheep-run without any habitations. The Town Council in 
1904 purchased the farm of 250 acres on which the 
impounding reservoir is situated and which comprises the 
greater part of the watershed. It includes 30 acres of 
arable land; but there is little or no danger of contamina- 
tion. The water is not filtered, but is of good quality. 
There are no trees on the area; but in the adjoining water- 
shed to the north there are large plantations ranging in 
elevation from 1000 to 1380 feet and from 1400 to 
1470 feet. The annual rainfall at the reservoir averages 
40 inches. The Borough Surveyor, Mr. G. W. Lacey, is of 
opinion that in general the control of the catchment area 
should be in the hands of the Water Authority, 
Hawarden and District Waterworks Company obtain their 
supply from four storage reservoirs at Cilcain, with a 
gathering ground on the Garth Stream, Moel Famma, of 
1400 acres, between 750 and 1640 feet elevation. The 
area, which is entirely hill pasture and moor, is not owned 
by the Company. The water is filtered; and no special 
precautions against contamination are considered necessary. 
Towyn Urban District Council obtains its water supply 
from (1) Rhydyronen Brook, with a gathering ground of 
215 acres, comprising 179 acres of hill pasture, 30 acres 
of arable land, and 6 acres of plantations; and (2) Bwlchgwyn, 
springs and gathering ground of 57 acres, comprising 
47 acres of hill pasture and 10 acres of arable land. In 
Journ. Board of Agriculture, xi. 471 (1904), 217 acres are 
said to be owned by the Council.
