area has a maximum of 123 feet. The mean depth is 50 feet. In the 

 narrows the depth at the western end is 10 feet, and at the eastern end 

 only 6 feet, while half-way between is a hole of 23 feet. The small 

 basin to the east of the narrows is on the whole shallow. Almost in 

 the centre is a shoal where the depth is only 2 feet, and close to this, 

 on the north, is a sounding of 30 feet. The greatest depth in this basin, 

 53 feet, is between the shoal and the narrows. 



Consideration of the contours and the nearly flat bottom shows that 

 there is the U-shaped section associated with glacier-hollowed lochs, 

 though, on account of the moderate depth, it is less clearly denned than 

 in many other large lakes. 



A series of temperatures taken in the deep part of the loch showed 

 a uniform reading of 51'8 Fahr. at all depths from 10 feet to 75 feet. 

 The bottom at 100 feet was a little cooler (51-2), and the surface a 

 little warmer (52-0), the total range being thus 0-8. 



Loch Lundie (by Clunie) (see Plate XCIX.). A small triangular 

 loch lying immediately to the north of Loch Clunie, about equally 

 distant from either end. The long axis runs nearly east and west, and 

 the greatest breadth is towards the west end. The outline is very 

 irregular, and there are several small islands near the shore. 



The height above sea-level on September 30, 1903, was found to be 

 681-5 feet, some 76 feet above Loch Clunie; the Ordnance Survey 

 officers on August 2, 1869, found it to be 681-9 feet. The length is 

 little under half a mile, and the greatest breadth one-fifth of a mile. 

 The superficial area is about 27 acres, the drainage area nearly 1 square 

 mile, and the contents amount to 9 millions of cubic feet. It receives 

 only some small burns, and is drained by a burn issuing from the south- 

 west corner flowing south a quarter of a mile into Loch Clunie. 



Loch Lundie is of no great depth, three-fourths of the superficial 

 area being covered by less than 10 feet of water. The area more than 

 10 feet in depth is narrow, and passes obliquely across the loch. The 

 greatest depth of 25 feet occurs at the extreme east end of this area, 

 and near shore, in a narrow part of the loch. 



The temperature on September 30, 1903, was the same at the surface 

 and at 20 feet, viz. 54-0 Fahr. 



Loch Loyne (see Plate C.). The two lochs under this name consist 

 of a chain of little basins or expansions of the river Loyne, connected 

 by narrow channels. The valley of the Loyne lies half-way between 

 Glen Clunie and Glen Garry, which are 2 or 3 miles distant. On the 

 north the lochs are separated from Loch Clunie by Beinn Loinne, 2500 

 feet in height. The hills on the south, though wild and bleak, are not 

 so high. The main road from Tomdoun to Clunie Inns crosses between 

 the two lochs. The valley to the west of the road has an east-and-west
