gneiss take another turn with the glen. At about 150 feet above 
the sea, the marks point N. 70° E., and aim at the shoulder of 
Wyvis, which bars the way. On this hill side are piles of drift. 
“ If Strath Bran held a glacier which flowed N. and E. 
towards Ben Wyvis, stones left by it ought to be blocks of 
white and grey quartz and gneiss, fragments of rocks in Strath 
Bran and near it. But there is no such collection of native drift 
here.” 
Page 153. — “ At 1000 feet up the side of Wyvis, the rock is laid 
bare in a small burn. It is a soft slate, dipping 10° south.” 
“ There are blocks of granite on the hill, and a moraine in the 
glen. But the granite is foreign. 
“At 1650 feet is a conical hill Clock Mor , — a lump of hard coarse 
conglomerate. The sides are scored, the steepest end is down stream 
towards the west. In the supposed “ ice ” are large blocks of mica 
schist, bits of grey quartz rock, and a big boulder of gneiss. 
“ At 3000 feet, the ground on a shoulder of Wyvis is smooth 
and flat, the rock shows in the edge of a deep corrie. It is a coarse 
gritty sandstone, which splits into thin flags. On this high shoulder 
are blocks of gneiss.”

lie) upon slate.”] 
In company with Mr. MacLean, factor for Ardross, Dr. Suther- 
land, Invergordon, and Mr. Joass, Dingwall, I visited Carn-Cuinneag 
(2744 feet) in Ardross. The hill has two peaks, from each of which 
enormous shoots of granite blocks have fallen, many of which weigh 
about 400 tons. In Stratli Ruasdale we saw on roadside a block of 
granite 22x 21x12 feet. Major axis JST. W. and S.E., and weighing 
about 462 tons. We observed to the W. on the sky-line on the 
ridge forming west flank of Glac-an-t-Seilieh, at 1600 feet above 
sea, a huge cubical block. E urther to the W. on the sky-line, on ridge 
close by north end of Loch Glass, is to be seen an immense erratic 
block, cubical, said to be the largest in Ross-shire. Carn-Bhren to 
17. E. of Cuinneag, reported to be granite. These two hills of 
granite are probably part of the same belt, which to S.W. crops 
up at Strathvaich. The country to S.E. of this belt is full of 
boulders, chiefly granite. Many hills on their N.W. faces denuded 
and sown over with blocks.
