Glendun. The clouds, which earlier in the morning loomed so 

 heavily, now gave us the benefit of their contents in heavy rain, 

 which continued for the greater part of the forenoon, This was 

 rather unfortunate, as it was intended to spend part of the day 

 along the steep sides of Glendun. The load of moisture, however, 

 on the foliage forbade this, and, after a short stop on Glendun 

 viaduct to enable the party to collect specimens of the mountain 

 fern ( Lastrea oreopteris), the road was again taken to Cushendun, 

 before reaching which the rain had cleared off, and an enjoyable 

 evening was spent examining the caves for which the place is noted. 

 These caves are huge excavations cut by the sea into a cliff of red 

 conglomerate. Unlike that at Redbay, the pebbles here are much 

 larger, ranging from the size of a paving-stone to more than a foot 

 in diameter. They appear to be all dense quartzite, and must 

 have undergone a vast amount of attrition previous to their depos- 

 ition. The paste which unites them is of a reddish-brown colour, 

 and appears just sufficient to combine all into a solid mass. 

 Asplenium marinum and other rock-loving plants were observed 

 here in the crevices of the conglomerates. A few of the party pro- 

 ceeded to visit some archaeological remains on the slopes of the 

 hill north of the village. The first, which may be termed a Cashel, 

 is perhaps one of the most perfect of its class in the North of 

 Ireland. It is a circular erection, with an internal diameter of 

 between fifty and sixty feet, and is strongly and regularly built of 

 large stones, no mortar having been used in its construction. The 

 walls are about nine feet thick, by the same in height. There is 

 an entrance to this circle by the eastern side, and there are also 

 the remains of what appear to have been rude steps from the 

 interior of the circle to the top of the wall. At the northern side 

 of the circle and within the enclosure is an opening, about two feet 

 square, which admits to a chamber built within the thickness of the 

 wall. An examination of this shows that it is closed by fallen 

 stones in one direction, but it appears open for some distance in
