REPORTS ON EXCURSIONS. 123 
party was taken, by arrangement, to Glen Oglehead Crossing, 
which was formerly the station for Killin. Walking a short 
_ distance northwards, the limestone and hornblende schist are 
seen dipping to the south-east—that is, in a direction opposite 
to that on the other side of Glen Dochart—which shows that the 
valley occupied by this glen and Loch Tay has been hollowed 
out of an anticlinal arch. The company thereafter retraced their 
steps down Glen Ogle. After tea at the hotel, the train was taken 
at Lochearnhead Station. 

Locuwinnocu, 24th April, 1897.—On the afternoon of this 
date a small party visited Calder Glen, Lochwinnoch. Among 
the plants noted were Chrysospleniwm alternifolium, Linn., Luzula 
pilosa, Willd., and Cystopteris fragilis, Bernh. At one place the 
stones in the running water were densely covered with the wiry 
olive-green filaments of an alga, Lemanea fluviatilis, Ag., one of 
the most highly organised of its class. Some of the filaments 
were nine or ten inches long. 






















Datmurr, 8th May, 1897.—Few turned out to the excursion 
arranged for the afternoon of this date to Loch Humphrey Burn 
and Loch and the Kilpatrick Hills. The small party proceeded 
‘by Duntocher to the Loch Humphrey Burn, and kept by the 
rocks on its side most of the way. The rocks having a western 
exposure are the best here for the botanist. At Greenside there 
is a sharp turn: in the burn, and the rocks face to the north, the 
_ *slacks” rising to 1,100 feet. Loch Humphrey was visited, and 
the return journey was made by the Hill Road (from which 
_ magnificent views were obtained) to the Station at Kilpatrick. 
_ Among the plants noticed were the ferns, Cystopteris fragilis, 
Bernh., Phegopteris Dryopteris, Linn. ; and the following mosses, 
Andreea petrophila, Ehrh., Lewcobrywm glaucum, Schp., Blindia 
— acuta, B. &8., Encalypta vulgaris, Hed., Brywm alpinum, Linn., 
 Polytrichum alpinum, Linn.
