and branches of which have for the most part been removed 

 by denuding agencies, running water, and ice, just as if Etna 

 were to be cut down into a group of hills two or three thousand 

 feet high. Looking from this commanding summit over the 

 other hilltops, we are perhaps better able to realise the action 

 of these denuding agents than when standing at the foot. 



Generally speaking, the glacial phenomena of the Mournes 

 are not very prominent. There are several small lakes, whose 

 bottoms may have been partly ground out by the ice and partly 

 dammed up with boulder clay. There are some enormous banks 

 of this latter material to be seen. There are some splendid 

 perched boulders left by the retreating ice, of which the Clough- 

 more stone at Rostrevor is the most famous, but on Slieve 

 Bingian is a much larger one. There are also the remains of 

 several moraines, left as the ice slowly retreated into the heart 

 of the mountains and the end of the great ice age had arrived. 

 One of these, the finest, crossed the Kilkeel Valley about its 

 middle. There is another very noticeable one across the upper 

 part of the Newcastle River, about a mile or less above Lady 

 Annesley's. But we must hasten down. The descent was 

 made by Blackstairs, where the dykes of basalt that traverse 

 both the granite and silurian rocks are well exposed. During 

 the excursion many rare plants were seen, but as the Club is 

 anxious to preserve their existence, the particular localities can- 

 not be mentioned. Of flowering plants there were noted Pingui- 

 cula lusitanica^ Saxifraga stellaris^ Lathrcea squamaria^ Neottia 

 nidus-avis^ Pyrola minor; of ferns twenty-two species, and of 

 mosses no.

DREDGING EXCURSION. 



Several members, deeply interested in the investigation 

 of marine life, have from time to time during the winter 

 sessions favoured the club with attractive notices of dredging 

 expeditions, and the exhibition of specimens obtained on
