and south-east direction, while the southern half trends almost directly 

 north and south. 



There are two depressions in which the depth exceeds 100 feet, with 

 an isolated sounding of 106 feet between them. The larger depression 

 is contained in the southern half of the loch, and is over half a mile 

 in length, with a maximum width of about one-sixth of a mile ; the 

 greatest depth in this depression is 118 feet. The smaller but deeper 

 depression is situated at the base of the northern half of the loch, 

 occupying a central position, and is over a quarter of a mile in length, 

 with a maximum width of about one-sixth of a mile. The deepest 

 sounding in the loch (146 feet) is centrally placed in this depression,

lying north-westward of the point where the Ardchullarie burn enters 

 the loch. The area of over 100 feet in depth is estimated at about 55 

 acres, or 9 per cent, of the entire area of the loch 



There are three depressions in which the depth exceeds 50 feet. 

 The largest is contained in the southern half of the loch, and is over 

 1J miles in length, with a maximum width of over a quarter of a mile. 

 The second in point of size is centrally placed, and is over half a mile 

 in length, with a maximum width of over a quarter of a mile. The 

 third and smallest (and also the shallowest, the deepest sounding in it 

 being 62 feet) is situated near the northern end of the loch, and is little 

 more than a quarter of a mile in length and about one-eighth of a mile
