romantic little gorge and glen down which the mountain streams 

 have cut their way to the shore, and the coast itself is full of 

 interest to the geologist, from the number of basaltic and other 

 volcanic dykes, some of which are in their turn cut across by 

 other dykes of a later date. The most noticeable feature from 

 the road, however, is the thick beds of moraine matter, full 

 chiefly of granite fragments from the hills immediately above. 

 As the party nears Kilkeel the rain gets lighter, and by the time 

 a few minutes have been devoted to some light refreshment in 

 the Royal Hotel the clouds have broken, the sun has burst out, 

 and we are revelling in a glorious July afternoon. Kilkeel 

 presents an aspect of bustle, for it is market day. We proceed 

 along the road to Rostrevor, past several old earthen forts, one 

 called the tl Mass Forth," reminding us of the nearly forgotten 

 days of the Catholic proscription. Near by is the present large 

 and handsome Catholic Church, and just beyond the corner of 

 the grave-yard are the remains of a very fine "giant's grave" 

 or kistvaen, about forty feet long. The covering stones of the 

 chamber, have, however, disappeared. On returning to the 

 hotel a substantial tea is done justice to, and the char-d-banc

 along the sandy spit on which the great castle stands, the Lon- 

 don and North-Western Railway Company's ferry steamer is 

 passed lying with steam up at the little pier ; but we have no 

 time for a trip to Greenore or Carlingford, so passing the coast- 

 guard station we climb the green artificial mound that ter- 

 minates the point. This is " Knock Tinnel," doubtless a great 

 burial mound of some forgotten chieftain ; but, as its name 

 purports, better known by tradition as the " Knock Tinoil," or 

 the hill of the assembly, from the summit of which edicts were 

 promulgated, and on which the chief stood or sat when his 

 followers swore allegiance to him. In a field close by stand 

 the west gable and belfry of Greencastle Church. The door 

 was at the northern side, and there is no trace of a chancel. It 

 is the usual old Irish type of a single oblong nave without 

 aisles. It groups picturesquely with the great castle behind
