gates, and other purposes. A nursery, two acres in extent, 
has recently been established. A scheme for planting 
146 acres on the grounds of the new reservoir has been 
sanctioned by the Waterworks Committee of the Corporation, 
and about 5 acres have been planted up to date. It was 
stated in the Mreeman’s Journal, 1st August 1913, that “an 
afforestation application had been made to the Development 
Commissioners for funds for the afforestation of the water 
catchment area at Roundwood”; but I can obtain no 
confirmation of this. An account of the Roundwood Water- 
works, with map of the catchment area, by J. G. O’Sullivan, 
appeared in Trans. Inst. C.E., Ireland, xxxiv. pp. 94-120 
(1908). 
Rathmines and Rathgar Urban District Council have a 
gathering ground of 7000 acres in the Dublin Mountains, 
in the Glennasmol Valley, comprising the headwaters of 
the river Dodder and its tributaries, the Slade and Cot 
Brooks, and situated in Allagour, Ballymorefinn, Glassa- 
vullaun, Castlekelly, Cunard, Glassamucky, and Piperstown 
townlands, extending from about 600 feet up to 2472 feet, 
the summit of Kippure Mountain. The gathering ground 
is made up of two distinct areas: an upper area of 4000 
acres, practically all moorland, covered with peat and large 
boulders, the supply from which is used only for compensa- 
tion water to millowners along the river Dodder. On this 
area there are three farm-steadings, with one dwelling-house 
and a shooting-lodge. The lower area, 3000 acres in 
extent, consists of bare mountain slopes free from peat and 
only suitable for grazing, but has 65 farm-steadings, with a 
dwelling-house attached to each, upon it. It is off the 
latter area that clear water is collected into the upper 
reservoir (at 578 feet elevation) for drinking purposes. 
The lower or millowners’ compensation reservoir has a top- 
water level of 495 feet elevation. The service reservoir at 
Ballyboden with filter beds is at an elevation of 327 feet.
