54 BOTANICAL EXCURSIONS MADE BY 
The summits of most of the mountains here are very rocky 
and stony, and walking on them is very painful and fatiguing, 
especially on a hot and sultry day. After visiting the Springs 
of the Dee we proceeded to the rocks near Loch Evnach, which 
we examined superficially, and deem worthy of careful examina- 
tion. Luzula arcuata, Aira alpina vivipara, and many alpine 
plants were seen on them. Leaving these rocks we bent our 
steps towards Cairn Toul, and on the ascent we gathered a 
Carex supposed to be Carex leporina, associated with C. curta 
var. alpicola. After a very fatiguing walk we reached the 
summit of Cairn Toul, picking Lusula arcuata on the way. We 
then descended by a rocky ravine towards the Dee. The 
descent was difficult and tedious. Some of the party were 
nearly knocked up by it. In a corrie of Cairn Toul I found 
Veronica alpina, Poa alpina, Phleum alpinum, and several other 
alpine plants. The hill deserves to be examined more 
thoroughly, and it is easy to reach it by taking a car from 
Braemar to the bridge on the Glen Tilt road, and then striking 
off to Glen Dee on the right hand. This is also a way of 
reaching one side of Ben na Mac Dhu, and it leads directly to 
the pass which conducts to the Spey. After reaching the Dee 
we proceeded by Glen Dee along the banks of the river. After 
walking a few miles we reached a sort of horse-track which 
conducted us to the Glen Tilt road, and ultimately to the Linn 
of Dee, where we arrived about 7 in the evening after a most 
laborious journey. A vehicle was here in waiting for us, and 
after partaking of a draught of porter and some biscuits, our 
only meal since 5 a.m., we reached Braemar in safety. 
Monday, 16th August 1847. 
The party walked by Invercauld to Lochnagar, picking on the 
way— Vaccinium Vitis-Id@a, Betula nana,and Parnassia palustris. 
We first made for the cliffs on the north-eastern side and 
examined them carefully. These cliffs surround a little loch, and 
some of them are very lofty and precipitous. Of late great falls 
of rocks have taken place. Various species of Aizeracium, 
especially H. alpinum, H. villosum?, H. Halleri, were seen in 
profusion, Ad/osorus crispus in a fine state, Veronica alpina. On
