afforest these areas, which are largely composed of peat, 
giving off at certain seasons water dark in colour and con- 
taining matter in suspension. Mr. W. A. P. Tait gave in 
Proc. Inst. Civil Engineers, vol. 159, pp. 329-341, Plate 11, 
fig. 1 (1903), an account of the Mid-Lanark water supply, 
with map showing its distribution and all the reservoirs in 
Lanarkshire. 
Hamilton obtains its water supply from two catchment 
areas: (1) Kype reservoir area, 2140 acres of moorland 
at 936 to 1556 feet above sea-level, the latter elevation 
being that of Goodbush Hill, north of Muirkirk. The area 
is rough grazing for sheep, and some peat, without any arable 
land or farm-steadings. Forty-four acres are owned by the 
Corporation. The annual rainfall averages 47°28 inches. 
The water is passed through sand filters. (2) Wellbrae 
and Cadzow area, 1480 acres of arable land and pasture, 
at 601 to 766 feet altitude. On Cadzow there are 
3 farm -steadings, and on Wellbrae 5 farm-steadings 
and 4 habitations, but all sewage is intercepted by fire- 
clay pipes and run past the reservoir. Fifty-six acres are 
owned by the Town Council. There are 20 acres of Scots 
pine plantation, and the annual rainfall averages 34°66 
inches. The water is passed through mechanical filters. 
The Bathgate District Committee of the Linlithgowshire 
County Council obtain their water supply from the Forrest- 
burn reservoir, south of Forrestfield Station, with a gathering 
ground in Lanarkshire of 1540 acres at 750 to 1000 feet 
altitude. This area consists of 1300 acres of hill pasture, 
200 acres of moorland, 20 acres of arable land, and 20 acres 
of tree plantations. It is not owned by the County Council, 
who have only the water rights; and as it is free from farm- 
steadings and habitations, no special measures are taken to 
prevent contamination of the water. 
Motherwell obtains its water supply from three catch- 
ment areas, as follows: 
1. Culter reservoir, 254 miles S.E. of Motherwell, has a
