{Western Islands^ vol. i. p. 515). Inch Kenneth is about 10 miles 
K.E. from Iona {Second Report^ p. 155). 
5. Staffa was visited by Convener. He found on it, at his first visit, 
several small boulders of red granite. There are no rocks of granite' 
on the island. It consists entirely of blue trap {Second Report, p. 1 57). 
In a small hay on east side of island, the Convener (on his 
second visit) found several small boulders of red granite, gneiss, 
quartzite, and limestone, none of which occur in Staffa as rochs. 
About 20 yards from this bay. Convener found an old sea-beach 
36 feet above high water mark, from the gradual breaking up of 
which the foregoing boulders are probably derived. 
Quotation given from Dr Macculloch to show how perplexed he 
was to account for the occurrence on Staffa of “ transported stones,” 
which, he assumes, must have been carried by natural agency from 
some of the neighbouring islands {Fifth Report, p. 11). 
6. Tiree. — (1) Haynish Hill, in S.W., end of island, reaches to 600 
feet above sea. It consists of gneiss, in some parts passing 
into granite. 
The hill on its west side coincides with sea-cliffs, and has on it 
a number of rocky knolls. Almost every knoll has on its K.W. side 
{i.e., facing the Atlantic) boulders more or less rounded. The 
following are particulars of some : — 
Boulder 11x8x5 feet resting on side of knoll facing W.N.W. 
Boulder 9x4x5 feet resting on side of knoll facing W. by K. at 
height of 360 feet above sea, which is a quarter of a mile distant, 
with access from the sea between S. and K.K.W. points. This 
boulder is a coarse granite, — the knoll is gneiss. 
Boulder 8x7x5 feet resting on side of knoll facing K.W. by N. 
at height of 365 feet above sea. Sea half a mile distant, and 
access from it open at any point between S.W. and due north. 
Two clusters of large boulders met with, the uppermost on the 
cluster so posed as to show it must have come from westward. The 
sea is within half a mile to westward. 
On this Haynish Hill boulders more numerous on sides or 
slopes facing W. and N.W. than on any other. On slopes facing 
E. and S.E. there are also boulders, but fewer in number. 
(2) Passing due north, along Big Cornish Road, Convener found 
on east side of road several rocky knolls, tops of which are from 80 to
