THE FRESH-WATER LOCHS OF SCOTLAND. 391 



Centrally, in the length of the loch, but nearer the south shore, is a 

 small area a quarter of a mile long, over 200 feet deep, with the 

 maximum sounding of 213 feet. The mean depth is 78 feet. The 

 contours show that the slope of the bottom is nowhere very steep, but 

 is steepest at the south side at the deepest part of the loch. There is 

 but little extent of flat bottom at depths of over 150 feet, but where 

 the depth is less than that, especially towards the west end, there is 

 a well-marked flat with steeper sides. 



The temperature at the surface was 42-4 Fahr., and at 170 feet 

 41-8, a difference of only 0-6. 



Loch a' Bhainne (see Plate XCVL). A very little loch, high up on 

 the hill to the north of Loch Garry, about 2 miles north of the east end 

 of that loch. It is roughly triangular, with the apex to the south. The 

 hills rise steeply from the loch to the west and north. It is fed by 

 streams coming from Mam a' Chroisg, and the Allt a' Bhainne flows 

 south-eastward 3 miles into the river Garry. The bottom is irregular, 

 the greater part covered by less than 10 feet of water, but there are 

 two holes of over 20 feet, the larger with the maximum of 28 feet 

 close to the east shore, the other with a depth of 27 feet to the south; 

 a sounding of 13 feet between the two. 



It is one-third of a mile long, a quarter of a mile in greatest breadth, 

 and one-seventh of a mile in mean breadth. The mean depth is 10 feet. 

 The superficial area is about 32 acres, and the volume 14 millions of 

 cubic feet. The drainage area is nearly 2 square miles. The height 

 above sea-level was estimated at 1060 feet. The temperature at the 

 surface and at 20 feet was 45-0 Fahr. on May 5, 1903. 



Loch Lundie (by Garry) (see Plate XCVI.). A small loch in Glen 

 Garry, on a tributary of the river Garry, about 1J miles north-west of 

 Invergarry, on Loch Oich. It is of irregular form, its outline broken 

 by various arms and promontories. A point on the west side, with an 

 island off the east shore (Eilean na Faoileige), cause a narrowing and 

 separate two expansions. From the northern expansion several narrow 

 arms run north-eastward. Loch Lundie is three-quarters of a mile long, 

 by fully one-third of a mile in maximum breadth, with a mean breadth 

 of one-fifth of a mile. The surface has an area of about 109 acres, and 

 the volume of water is 78 millions of cubic feet. The drainage area is 

 about 3 1 square miles. The Allt Lundie comes in on the west, and the 

 Aldernaig burn, soon joined by the Allt a' Bhainne from Loch a' 

 Bhainne, flows south into the river Garry. The height above sea-level, 

 measured by the Ordnance Survey on August 18, 1869, was 445-4 feet. 



The contour of the bottom is very uneven. The 20-feet contour 

 enters both expansions, keeping closer to the west shore. In both of 

 the expansions there is a depth of 30 feet close to the west side. The
