the Carriston area. The Coul gathering ground is mainly 
pasture, but has four farmhouses, with five farm-steadings 
and byres, a keeper’s house, and a mill upon it. The 
Carriston area is largely arable land, with some plantations 
upon it, which are now being cut down. It has a consider- 
able population, with 21 houses of various kinds, 2 shops, 
a sawmill, and 10 farmsteads, byres, etc. Some of the 
farm-steadings and byres are fitted with sewage tanks and 
pumps. The water is filtered.
