Journ. Board of Agriculture, xi. 472 (1904), that the 
Burgh owns 100 acres of catchment area, I am informed, 
is incorrect. 
The Central District of the County of Linlithgow are con- 
structing on the Riccarton Burn, two miles south of 
Linlithgow, the Bescraigs reservoir, with a gathering ground 
of 560 acres. The Corporation own none of the land, 
which consists of 160 acres of arable, 100 acres of pasture, 
occasionally ploughed, 250 acres of permanent pasture, and 
50 acres of plantations. There is a farm-steading, but a 
drain has been constructed to take the sewage past the 
reservoir. In the opinion of the engineers, “it would be

this area were afforested, in view of the fact that so large 
a portion is arable land.” It ranges in elevation from 500

heather moor, at 950 to 1753 feet altitude on the north

reservoir, west of Garvald, with a catchment area of 1070 
acres, at 700 to 1306 feet elevation; and from the Thorter 
reservoir, south-east of Garvald, with a catchment area of 
900 acres, between 810 and 1400 feet elevation. The 
gathering grounds, which are on the northern edge of the 
Lammermuir Hills, consist of hill pasture, without any 
population, there being only one shepherd’s hut, which 
is on the Donolly area. A small piece of cultivated 
ground near one of the reservoirs does not drain into it. 
No special precautions, except filtration of the water, have 
been considered necessary by the Town Council, who own
