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
