two areas, which “are kept clean. During heavy rains no 
water is allowed to get into Ballysallagh reservoir.” 
Newcastle (Co. Down) obtains its water supply from a 
gathering ground of 500 acres, between 800 and 2515 
feet elevation, in Ballaghbeg, embracing the upper 14 mile 
of the Glen River, and all mountain grazing, without habi- 
tations or plantations. The water, coming off a granite 
formation, is very pure, and is piped from the intake at the 
800 feet contour line to the service closed reservoir in 
Donard demesne. The water supply and gathering ground 
belong to Lady Mabel M. Annesley. 
Portadown and Banbridge Joint Waterworks Board obtain 
their supply from a gathering ground of 943 acres, be- 
tween 900 and 2300 feet elevation, in the townlands of 
Fofannyreagh, Fofannybane, Moyad, and Cock Mountain 
Common in the Mourne Mountains. The headwaters of the 
Shimna River are collected off this area by a dam thrown 
across the river at Deer’s Meadow in Fofannyreagh, forming 
a storage reservoir, with a capacity of 75,000,000 gallons. 
The Board own the entire area, which is all mountain 
grazing, without habitations or plantations. One of the 
streams supplying the reservoir is diverted past it in time 
of floods, being slightly peaty. The water is not filtered. 
The lower part of the gathering ground might possibly be 
afforested; but it is composed, according to Mr. R. H. 
Dorman, M.Inst.C.E., of steep and barren slopes of very 
little value even for sheep grazing. The average annual 
rainfall is estimated at 70 inches. See Proc. Assoc. Muni- 
cipal and County Engineers, vol. xxxii. pp. 133-143 
(1907). 
Warrenpoint: supply from gathering ground of 2694 
acres in the townlands of Mourne Mountains West, Rostrevor 
Mountains, Killowen Mountains, and Kilfeaghan Upper,
