THE FRESH- WATER LOCHS OF SCOTLAND.

of the survey it rose some six inches above the surface of the water. 
The main basin is contained in the north-western portion of the loch, 
where the bottom falls in two places below the 100-feet level, separated 
by a slight shoaling of the water over a short interval. The larger of 
these two 100-feet areas near the centre of the loch is three-quarters of 
a mile in length, and the smaller, half a mile in length, approaches 
within less than half a mile from the north-west end, running com- 
paratively close to the south-eastern shore. It is curious to note that 
the maximum depth observed in each of these two areas is identical (122 
feet), though the two soundings are separated by an interval of about 
a mile ; the deepest water on the rise between the two areas is 83 feet. 
The slope along the north-eastern shore towards the north-west end of 
the loch is very steep; in one place a sounding of 91 feet was taken 
about 20 feet from the shore, and the cliff above was almost vertical and 
50 feet in height. The areas between the consecutive contour-lines, and 
the percentages to the total area of the loch, are as follows: —

Cam Loch was surveyed on August 27 and 28, 1902. The elevation 
of the lake-surface above the sea could not be determined, but when 
levelled by the Ordnance Survey officers on October 7, 1871, it was 
found to be 404-8 feet above sea-level. Judging from the level of the 
other lochs in the district at the end of August, 1902, its level was 
probably about a foot lower than that quoted, and the boatman stated 
that he had never seen the water more than two or three inches lower ; 
the highest drift-mark seen was 3-7 feet above the surface of the water 
on August 27, 1902. The temperature of the surface water was 56°*2. 
Loch Veyatie (see Plate XXXVIII,).— Loch Veyatie lies about half 
a mile to the west of the village of Elphin. It receives the water from 
the Cam Loch at its south-eastern end, where also the Amhainn a’ 
Chnocain enters the loch ; the water is discharged at the north-western 
end of the loch by the Uidh Fhearna into the Fionn Loch. The ground 
around the loch is low, except where Cul Mor rises to a height of over 
2700 feet to the south-west, and Suilven (already referred to) to 
the north-west. The loch is over 4 miles in length, with a maximum 
breadth of nearly half a mile, the mean breadth being nearly a quarter 
of a mile (or about 400 yards). Its waters cover an area of about 593 
acres (or nearly one square mile), and it drains directly an area of over
