Visited Glas Maol and had a splendid view of all around as 
the day cleared up. Saw the Lomonds in Fife, Pentlands, and 
Edinburgh? Ochils, Ben Lawers, Ben Nevis, all the Braemar 
hills. _ Descended from Glas Maol, joined the road about 
three miles from the Spital of Glenshee, and joined the car at 
the bridge about 6 p.m. and returned to Castleton. 
Tuesday, 15th August 1854. 
The morning being fine we breakfasted at 6 a.m. and started 
at 7 by conveyance to the Linn of Dee, accompanied by 
Mr. Rathay and Mr. Esson (in all 15). Mr. Barclay had a horse 
and guide to meet him at the Linn of Dee and take him to 
Loch Etchachan. We walked by Glen Lui after seeing the 
Linn of Dee andthe Mar Forest. We gathered Avadzs petrea 
in stony places in the bed of the Linn. 
- Remarked particularly in all the old firs deprived of their bark 
the spiral arrangement of the wood. The trees were dead. Got 
a curious knot from one of the trees for the Museum. Walk 
up Glen Derry to Loch Etchachan and then to the top of 
Ben na Mac Dhu, which we reached between 1 and 2 
‘way gathered Luzula arcuata and some other rare plants 
n or about the summit among the plants seen were :—
