falling in a magnificent cascade into Loch Veyatie. The ground in the 
immediate vicinity of the loch is low, but to the east lies Cnoc na Sroine, 
and to the north-east Cnoc na Leathaid Bhuidhe, while to the west- 
north-west Suilven, and to the north Canisp, form remarkably fine 
objects, which catch the eye from every part of the loch. The length of 
the loch is 2 1 miles, the maximum breadth over three-quarters of a 
mile, and the mean breadth over one-third of a mile. Its waters cover 
an area of about 647 acres, or over one square mile, and it drains 
directly an area of over 16 square miles, but since it receives the 
outflow from Lochs Borralan and Urigill its total drainage area is about

33J square miles. Over 200 soundings were taken, the maximum 
depth observed being 122 feet. The volume of water is estimated at 
1,062,543,000 cubic feet, and the mean depth at nearly 38 feet. The 
south-eastern portion of the loch is shallow, very few soundings ex- 
ceeding 20 feet being recorded, the maximum observed being 40 feet a 
short distance to the east of Eilean na Gaoithe. Most of the islands are 
found in this part of the loch, Eilean na Gartaig being the largest, while 
Eilean na Gaoithe is remarkable for the long spit of sand and shingle 
which stretches from its northern point for a distance of nearly 100 
yards ; this spit is submerged when the water is high, but at the time
