The district occupied by these kaims was tolerably flat, and about 
2J miles wide (in an east and west direction) across the general 
course of the Eiver Spean. 
There were several lines of kaims all approximately parallel, 
and presenting a slight curvature; — the inner curves facing the 
north, or down the valley of the Spean. 
At one place there was an interruption in the continuous line 
of the northernmost bank, as if it had been broken through by 
some agent from the north; and I took a rough sketch of it on 
the spot, being fig. 1 on Plate XIII. 
At A, the kaim BC ceases for about twenty yards; and between 
this “ break,” and the other bank DE, there is a heap of 
boulders. 
The highest and thiekest of the two banks is BAG, and on it 
the greatest number of boulders are accumulated. 
On the low ground to the north of these kaims there are many grey 
granite boulders of various sizes scattered about, mostly angular. 
There two knobs about twelve or eighteen feet high attracted 
my attention, in consequence of there being boulders on their tops. 
One of the knobs was of detritus; the other of rock^ sloping down 
steeply on all sides, except the east. 
In each case the diameter of the flat surface at the top was 
about six or seven yards, and there were five or six boulders on 
each; — most of the boulders were on the sides facing the X. and 
X.W. 
In several places^ and especially at the north base of the most 
northern kaim, BAG, there were boulders piled over one another. 
On studying these, I became impressed with the belief that the 
uppermost boulder, being the last which came^ should show the 
quarter from which it must have come, to get into its position. 
Diagrams on Plate XII. represent these cases, showing that the 
boulders had come from some northerly point.* 
There was one place where rocks in situ of grey granite were 
found smoothed ; the smoothed face being towards the north, 
and a boulder lying on that side. The farther progress of the 
boulder to the south had been apparently obstructed by the 
smoothed rocks. This case is shown by fig. 1, Plate XII. 
* Explanations of the Plates are appended to this notice.
