merely a " casual," as some suspect. Anthriscus vulgaris was 

 found near Greenore plentifully, and Geranium pyrcznaicum at the 

 same place. The horned poppy (Glaucium luteum) also occurs 

 on the sandy shores. The low ground of Greenore point is 

 formed in part of a raised beach, indicated on the Survey map as 

 a locality for worked flints, and in which many layers are formed 

 entirely of the Carlingford oyster, which has still survived to be a 

 feature in Irish gastronomy. The surface of the limestone in the 

 quarry near Greenore bears marks of ice action, the grooves and 

 striations of which bear ample testimony to the enormous mass of 

 ice which must at one time have helped to plough out the rock 

 basin which now forms the Newry valley and Carlingford Lough. 

 Testimony is also borne to the same facts by the soundings shewn 

 on the charts, the rocks which nearly close the entrance opposite 

 Greenore, with the depth of water (seven fathoms) within, indicating 

 that Carlingford Lough is one of the true rock basins which, ac- 

 cording to the theories of Professor Forbes and Mr. Geikie, are 

 to be found opposite most of our glacier valleys. 



During the ascent of Carlingford mountain fifteen species of 

 ferns were found, amongst which was an abundance of the beech 

 fern ( Polypodium phegopteris). Of the parsley fern ( Cryptogramme 

 crispa), two specimens were seen, on nearly inaccessible cliffs, but 

 were not gathered, in conformity with the wise rules laid down by 

 the Club, whose motto " protection, not extinction " might be 

 more often kept in mind by collectors. 



Near the summit were found the Cow berry ( Vaccinium vitis- 

 idcea), Rose root (Sedum rhodiola), and the mountain meadow 

 rue (Thalidrum montaftum), the two latter being additions to the 

 flora of district 5 of the Cybele Hibernica. 



This closed the work of a most interesting and successful ex- 

 cursion.
