of Edinburgh, Session 1872-73. 
The Rev. Mr M‘Ewen, of Edderton, suggested the hills at 
or near Rogart, due N. or N. by E. from this spot about 10 or 
12 miles, as the rocks there of grey granite. 
These boulders not favourable to glacier theory. Their 
elevated positions, and the absence of any hills to the west or 
north nearer than 5 or 6 miles, are circumstances which render 
that theory almost impossible. 
Rosskeen. — Ardross. Numerous large boulders, their longer axis 
nearly E. and W. 
No. 1. March stone between Newmore and Ardross, about 
50 feet in girth, and 8 feet above ground. 
No. 2. At Achnacloich, at road-side, granite boulder 40 feet 
in girth. 
No. 3. About half a mile above Ardross Castle, by way-side 
in a dyke, about 100 feet in girth, and 9 feet above ground. 
No. 4. In a field opposite No. 1, of similar shape and size. 
District between Tain and Tarbet Ness . — Shows on surface neither 
boulders, nor gravel, nor sand, but traces of mud, and occa- 
sionally of boulder clay, visible. At Fort-George, boulder 
clay reported 100 feet deep and more. Mr Stables, of Cawdor 
Castle, bored into it for water to that depth, and did not get 
through it. 
If land was submerged 2000 feet, district about Fort-George, 
Moray Firth, Dingwall, Cromarty, &c., would be deeper than 
adjoining districts, and would be filled with muddy sediment, 
whilst shallower districts would be covered with gravelly and 
sandy sediment. The valley now occupied by Loch Ness and 
Caledonian Canal then a strait or kyle, through which tidal 
currents would pass ; and if icebergs and drift ice came from 
westward, boulders and debris would be deposited on what are 
now the low lands of Moray, Banff, Elgin, and Ross, with the 
intervening Firths. 
At Tarbet Ness, Balnabruach boulder visited, in company 
with Rev. George Campbell ; a coarse reddish granite 33 
feet in girth, and about 7 feet high. Longer axis E. and W. 
This boulder and another, not quite so large, near it, at sea 
level. Supposed to have come from “ Carn na Cunneig” hill, 
which visible from boulder, bearing W.N.W. about 30 miles, 
vol. vnr.
