party was taken, by arrangement, to Glen Oglehead Crossing, 

 which was formerly the station for Killin. Walkinsj 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. 



LocHWiNNOCH, 24th April, 1897. — On the afternoon of this 

 date a small party visited Calder Glen, Lochw^nnoch. Among 

 the plants noted were Chrysos2)leniumaUernifoliic7n, Linn., Luzula 

 pilosa, Willd., and Gystopteris fragilis, Bernh. At one place the 

 stones in the running water were densely covered with the wiry 

 olive-green filaments of an alga, Lemanea Jluviatilis, Ag., one of 

 the most highly organised of its class. Some of the filaments 

 were nine or ten inches long. 



Dalmuir, 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., Fhegopteris Dryopteris^ Linn. ; and the following mosses, 

 Andrece,a petrophila, Ehrh., Leucohryum glaucuTii, Schp., Blindia 

 acuta, B. <fe S., Encalypta vulgaris. Had., Bryum alpinum, Linn., 

 PolytricJium alpinum, Linn. 



Ross Hall, Crookston, 11th May, 1897. — A few members 

 visited the gardens and conservatories at Ross Hall on the evening 

 of this date.
