PROFESSOR JOHN HUTTON BALFOUR. 419 
Mr. Kennedy and Mr. W. Dixon went to Killiecrankie and 
Pitlochry by train and returned in the evening. 
Friday, 9th August 1867. 
This day the party divided into two. Mr. Fraser and Mr. 
Edmond again visited the great corrie of Ben Alder along with 
Donald Kennedy ; they rowed in a boat to the shooting-lodge 
and met Mr. Clark, who accompanied them during the day, and 
then walked seven or eight miles by the west side of Loch Alder 
to the corrie. They gathered in the loch Littorella lacustris, 
Subularia aquatica, [soétes lacustris (very fine). In the corrie 
they collected abundance of Polypodium flexile, Cryptogramme 
crispa, Carex pulla, as wellas Polypodium alpestre, Veronica alpina, 
and returned about 8.30 p.m. The remainder of the party, now 
numbering eight, proceeded at 7 a.m. by a drag, calling at Cat 
Lodge on the way and meeting Mr. and Mrs. Armitstead, passed 
the inn at Loch Laggan, and went about 34 miles along the side 
of the loch. They then proceeded under the guidance of Donald 
Fraser, keeper to Captain Edwards, to Corryarder, a high hill, 
probably 3600 feet, the summit being distant about seven or eight 
miles by the road taken by the party. The party went by the side 
of the Spean to the foot. of the steep cliffs covered with snow. 
Patches were several hundred feet in length, one of these patches 
arched so as to form a vaulted passage about two hundred or 
more feet long. The height of the arch was about seven feet 
throughout, and the snow very hard. Under the arch the 
party took shelter from a severe shower. The rocks are in 
great part inaccessible on account of their steepness: they were 
promising, but they did not seem to be so productive as was 
expected. 
The party went along the foot of the cliffs to the large gap 
called “the window of Corryarder,” and intended to visit other 
corries on the opposite side, but too much time was occupied on 
the first cliffs, and a severe shower of hail and rain arrested 
their progress, To examine the rest of the mountain fully 
would require several rsh It is an excursion worthy of 
attention. ‘
