BATHYMETRICAL SURVEY OF 
THE RESERVOIES OF THE FORTH BASIN, 
The principal lochs draining into the Forth were sounded by Sir John 
Murray and the late Mr. Fred. P. Pullar, and formed the subject of the 
first two papers published in the Geographical Journal in April, 1900, and 
March, 1901. The Lake Survey stafi' subsequently sounded most of the 
reservoirs and small lochs around the Firth of Forth, to the number of 
twenty, of which ten are situated to the south, and ten to the north of the 
firth (see Index Map, Fig. 26). 
The basins are, for the most part, small and shallow ; only four exceed 
a mile in length, and only four exceed 50 feet in depth, while, with one 
exception, the superficial area is in each case much less than half a square 
mile. The officials of the various waterworks facilitated the work by 
providing boats, maps, etc., for the use of the staff, and in this connection 
we desire to thank Mr. W. A. Tait, c.e.. Engineer of the Edinburgh and 
District Water Trust, for many facilities in connection with the Edinburgh
