red granite boulder, weighing about 150 tons, called the 
11 G-eadh,” or “ Goose,” 24 x 18 x 6 feet. Longer axis, S.E. 
(See Plate, Sketch No. IX.) 
About J mile farther north, on east shore, another large 
red granite boulder, about 12 feet square. East end rests on 
clay-slate rocks of island. West end rests on a smaller granite 
boulder. Eocks below boulder decayed out, so that possible 
to creep under boulder. Groove on bottom of boulder running 
N.E. as if pushed over rocks from that direction. This 
boulder very rounded at angles, apparently from friction. 
Boulder of red granite on side of highest hill in island, 
called “ Dun Ii.” Cubical in shape, and very angular, 
22x16 x16 feet. Boulder lies against steep slope of hill 
facing N.N.W., at height of 230 feet above sea. 
Convener found red granite boulders of smaller sizfe, at 
height of about 400 feet, the highest point of island. 
Mr Allan McDonald, schoolmaster, says that these granite 
boulders seem to be of same variety as that in Boss of Mull ; 
but he thinks granite does not occur there so high as 300 feet. 
Boss of Mull bears from this spot S.S.E. The “Dun Ii ” hill 
lies between Boss of Mull and this boulder. 
When asked by Convener if any red granite in Islands of Tiree 
or Ulva, to north of Iona? Mr M‘Donahl said there was none. 
Bocks on Iona more smoothed at the highest levels than at 
lower levels. 
Smooth faces of rocks front N. by E. The rough faces all 
front south. 
At south end of Iona a number of granite boulders (mostly 
red, but a few of grey variety) lying on the high ground, from 
200 to 250 feet above sea. One of these standing up on 
end, leaning against a rock on S.W. side of boulder, show- 
ing that boulder came from N.E., and was obstructed by rock in 
its farther progress to S.W. (See Plate, Sketch No. XI.) 
Most of boulders in south end of Iona lie with longer axis, 
N.E. and E.N.E. 
Some of the boulders in this district in such positions, that 
they could not have come into them, except by floating ice, 
brought from northward, and by eddying currents.
