REPORTS ON EXCURSIONS. 253 



sixteen, six of whom were members of both societies. In the glen 

 the left bank of the Calder was followed to a point a little below 

 the waterfall. The return was made by the road to Lochwinnoch, 

 and some of the party afterwards visited the shores of Castle- 

 Semple Loch. 



Owing to the backwardness of the season, Flowering-plants were 

 not conspicuous ; but as the glen is a rich one for Mosses, the 

 botanist members of the party found plenty of material for the 

 study of bryology. Most time was spent in an examination of 

 the moss covered banks and rocks along the edge of the old mill- 

 lade in the lower part of the glen, as, owing to the cloudy sky, 

 the more densely-wooded portions further up the glen were 

 enveloped in semi-darkness. 



With regard to ornithology, Mr. Ross reported that 34 species 

 of Birds were noted, inclusive of those seen on Castle-Semple 

 Locli. No summer visitors were among the species observed. 

 The Fieldfare was seen near the head of the glen ; about 

 the marshy ground at the side of the loch many Meadow Pipits 

 were in song ; while in the water were the Mallard, Teal, Widgeon, 

 Pochard, and Tufted Duck. A small flock of Golden Plovers 

 were seen to fly over the loch, uttering their call. 



Reports on the Mosses and Hepatics of the glen were submitted 

 by Mr. Lee, and on the Microfungi by Mr. Boyd. 



Arran, 20th April 1908.— Mr. J. W. Reoch, conductor.— This 

 excursion was arranged jointly with the Geological Society of 

 Glasgow, and attended by a party of nineteen. From Brodick 

 Pier the direction taken was eastward along the Corriegills Shore 

 to Clauchland Point, thence up the ridge of the Clauchland Tlills 

 via Dun Fionn and Dun Dubh, and thence back to Brodick by 

 road. 



The old sea-beach is a marked feature on this part of the coast, 

 as it also is around nearly the whole circumference of the island. 

 Here it forms a broad platform backed by cliffs inland. The 

 pools on the foreshore teem with life, and the botany of the 

 marshy platform and the cliffs behind is rich. 



The sedimentary rocks exposed along the shore are alternating 

 sandstones and conglomerates of Lower Triassic age, with a 

 general southerly dip, and they afford throughout the entire route
