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 1^ mile 

 of the Glen Eiver, 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 

 Eofannyreagh, Fofannybane, Moyad, and Cock Mountain 

 Common in the Mourne Mountains. The headwaters of the 

 Shimna Eiver are collected off this area by a dam thrown 

 across the river at Deer's Meadow in Eofannyreagh, 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

 The lower part of the gathering ground might possibly be 

 afforested ; but it is composed, according to Mr. E. 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-
