land, 50 acres of moor, and 550 acres of plantations, with 
two small houses upon it. The water is filtered, but “as 
the gathering ground is not under cultivation, no measures 
are necessary beyond constant supervision.” 
Stratton and Bude Urban District Council obtain their 
water supply from the Tamar Lake, supplied by overflow 
from the river Tamar and two small streams. The water 
is filtered, I have not been able to obtain any information 
about the gathering ground. 
South Molton obtains its water supply from a gathering 
ground of 400 acres, at about 800 feet elevation, on North 
Molton Common, Exmoor. There are no dwelling-houses, 
farmsteads, or plantations upon the area, of which only three 
acres are owned by the Council. Cattle and sheep are kept 
from the springs and rivulets by fences. The water is not 
filtered. 
Exmouth obtains its water supply from two gathering 
grounds, Squabmoor, 351 acres, and Bicton Common, 290 
acres, making a total of 641 acres, situated between 264 
and 550 feet elevation, and consisting of 75 acres of planta- 
tions, 74 acres of pasture and arable land, and 492 acres 
of common land. These areas were acquired in 1902 by 
the Council, who “are of opinion that no future steps 
are necessary to maintain the high state of purity of the 
water supply.” The water, which is stored in Squabmoor 
reservoir, is filtered, and is reported by the analyst to be 
satisfactory ; it acts on lead, but lead pipes are not allowed. 
Two small additional areas of 41 and 35 acres make now 
the total extent of the gathering ground 717 acres. An 
interesting account of the geological structure and rainfall 
is given by Mr. S. Hutton, in Proc. Inst. Municipal and 
County Engineers, vol. 36, p. 132 (1910). 
Plymouth obtains its water supply from the river Meavy 
watershed on Dartmoor, 5360 acres in extent, between 750
