Manchester; about 6400 acres are owned by the Man-

 Waterworks Joint Committee obtain their supply from three 

 catchment areas :

Total . . 4730 



The storage reservoirs with their elevations above sea- 

 level are : Brushes, 649 feet; Lower Swineshaw, 871 feet; 

 Higher Swineshaw, 957 feet; Yeoman Hey, 768 feet; and 

 Greenfield, 892 feet. There are also two compensation 

 reservoirs — Walker Wood, 588 feet, and Chew, 1600 feet. 



The Joint Committee have purchased and own 2500 

 acres, namely, 1310 acres in Greenfield area, 70 acres in 

 Swineshaw area, and 1120 acres in Chew area. There is 

 one holding on Greenfield area, one holding on Swineshaw 

 area, and two holdings on that part of Chew area which 

 is not used for domestic supply ; but there are restrictions 

 as to manures, and animals kept on the farms, besides close 

 inspection. The water is filtered. There are the remains 

 of what were formerly plantations, but which now consist 

 of a few straggling trees only. This appears to be due to 

 atmospheric change, as there is evidence that in days gone 

 by trees were very prevalent and flourishing on the 

 gathering ground. The engineer, Mr. G. R. Raddin, 

 B.E., says it is more satisfactory to have ownership 

 control of the area, as there is less trespassing, better 

 regulation of indiscriminate rambling, with restrictions as 

 to manuring land and grazing of cattle, and with poM^er to 

 clear land of farms. 



Stockport obtains its water supply from two catchment 

 areas — Lyme Park area, 1400 acres, between 650 feet and
