THE FRESH- WATER LOCHS OF SCOTLAND. 245 



of 416 and 419 feet, separated by an interval of three-quarters of a 

 mile (in which the greatest depth is 375 feet) from the larger, which 

 is less than a mile in length and encloses the maximum depth of the 

 loch (420 feet), recorded near the north-eastern end of this larger basin, 

 and over 4 miles from the head of the loch. The line of soundings, 

 which includes the deepest one, is shown on cross-section G-H on map 

 (Plate LIIL).

From the foregoing description, it will be noticed that in Loch Shiel 

 the deeper water occurs towards the head of the loch. Proceeding from 

 Acharacle, at the foot of the loch, one must row 2 miles up before 

 encountering a depth of 50 feet ; a further 1 J miles before meeting with 

 a depth of 100 feet, and this merely a small patch, a further 1J miles 

 having to be traversed before reaching the main 100-feet basin, or a 

 total distance of 5 miles from the foot of the loch. The main 200-feet 

 basin is distant about 9 miles, the lower 300-feet basin nearly 10 miles, 

 and the principal 400-feet basin over 12 miles, from the foot of the 

 loch.
