land and pasture, and 75 acres of wood and moorland, 110 
acres in all. 
On the catchment area of the Auchendores and Leper- 
stone reservoirs, which are contiguous, there are several 
farm-steadings, the drainage of which is diverted past the 
reservoirs by a pipe drain. There are arable fields adjoining 
the reservoirs; but the possible contamination from these

have no control as to how the land is to be used. 
The District Committee of the First or Upper District of 
the County Council of Renfrew obtain their water supply
