THE FRESH- WATER LOCHS OF SCOTLAND. 373 
from an area of over a square mile, by small burns only, and flows out 
by the Water of Kiachnish into Loch Linnhe. 
At the date when surveyed (May 9, 1903) the height above sea-level 
was 510'1 feet, exactly one foot lower than the elevation determined 
by the Ordnance Survey officers in May 1867. 
The basin of Lochan Lunn da-Bhra is broken by islands, about a 
quarter of a mile from each end and nearly in the middle of the loch. 
The island towards the upper end is on a bar, the greatest depth to the 
north-west and south-east of it being respectively 9 and 8 feet. This 
bar cuts off a separate small basin, with a maximum depth of 21 feet. 
The greatest depth of the loch, 25 feet, was found not far to the north- 
east of this island. North-east from the lower island it is everywhere 
shallow, nowhere exceeding 7 feet. 
The shores of Lochan Limn da-Bhra are composed chiefly of gravel 
with boulders, which form many heather-covered mounds. Bock is 
exposed in many small spots. The stream flows out through a flattish 
tract, covered with moraine mounds, about half a mile long, and rock 
was seen in the channel at a distance of about 100 feet from the 
loch. The promontory below Lundavra farm has been laid down by 
the stream. 
We were told by the local inhabitants that the loch will sometimes 
freeze all over in a single night, and that small dark trout are abundant 
in it. There are also some pink-coloured trout, and others silvery like 
salmon. 
The temperature was 48°*0 Fahr. throughout. 
Loch nan Gahhar (see Plate XC.). — Loch nan Gabhar (or Gour) is 
a little weedy hollow lying close to the sea-shore, and very little above 
sea-level, on the west side of Loch Linnhe, nearly opposite Ballachulish. 
It runs nearly east and west, and occupies the southern portion of a 
large oval alluvial flat, in the midst of which rises an abrupt boss of 
rock, the Torr an Duin, apparently some 70 or 80 feet in height. This 
alluvial flat is surrounded by steep rocky hills, which form the southern 
shore of the loch. 
The loch is of very irregular form, and interrupted by narrows, 
bays, and promontories. It is fully half a mile long, one-sixth of a mile 
in greatest breadth, and one-eighth of a mile in mean breadth. The 
maximum depth is 5 feet, and the mean depth 2J feet. The area of the 
water surface is only about 45 acres, and it receives the drainage of 
13 square miles of country. The height above sea-level, on the date 
when the survey was made (May 12, 1903), was 7’35 feet, as compared 
with 7-5 feet observed by the officers of the Ordnance Survey on 
July 19, 1867. 
Loch nan Gabhar receives by the river Gour the drainage of a 
considerable mountainous stretch of country, bordering Glen Gour,
