morainic accumulations, consisting of sand and gravel with 

 contents similar to those found near the Shooting Lodge. 



The stratified deposits in the upper part of the valley were 

 accumulated in a lake, which overflowed at a level of about 950 feet 

 into Glenaan by way of a channel between Crocknacreeva (1092 

 feet) and Aghan (1197 feet). 



Below the junction of Clyttaghan Burn there is a continuation of 

 the gravelly deposits, which are again confined to the lower slopes. 

 These extend down to the 50-foot contour below the viaduct, where 

 they are replaced by another series which forms a dissected terrace 

 at about 25 feet above sea-level, and is described on the maps of 

 the Geological Survey as ' Raised Beach.' There is an extremely 

 good section in this deposit immediately above the bridge over the 

 river at Cushendun. A bend of the Glendun River is at present 

 cutting into the terrace. The section is 30 feet high, and the 

 base of the deposits passes below the level of the stream, which 

 at this point is tidal. The gravels are strongly current-bedded, 

 and contain layers of red laminated clay. The pebbles include 

 quartzite, sandstone (Old Red), schist, flint, purple porphyrite, 

 vein-quartz, also a granite with pink porphyrinic felspars, which 

 occurs in situ at the elbow of the road a mile north-west of 

 Cushendun. 



At the base of the gravels, at about high-water level, is a bed 

 of silt containing fragments of wood and some roots, probably 

 of a species of willow, the position of which suggests that they 

 are in their place of growth; also hazel-nuts, a vertebra (probably 

 of Sus scrqf'a), and some marine shells, including Gar Mum edule 

 and Littorina littorea. The silt appears to rest upon the 

 boulder-clay ; but this part of the section, being below tide-level, 

 is difficult of access. 



The portion of Glen dun which lies above the Shooting Lodge is 

 of particular interest, as it contains evidence of glaciation by local 

 ice which (with that at Newtown Crommelin shortly to be 

 described) is the only indication that I have found in this part 

 of Antrim. About 2 miles above the Shooting Lodge, at a height 

 of 950 feet, a small, but distinct, terminal moraine crosses the 

 stream with its convex face down stream, consisting entirely of 

 basalt-boulders and basaltic detritus. It is evidently the product 

 of a glacier emanating from a snowfield in the great basin which 

 lies between Bush Head and Pollan Bridge, in the triangle between 

 Trostan (1817 feet), Slievenanee (1782 feet), and Eagle Hill. 



The long spur which runs from Gruig Top towards Cushendun 

 is covered by great numbers of enormous boulders of the local 

 schist. 



Glenaan. — Glenaan shows no sign of the local glaciation, the 

 Scottish drift being plentiful up to 1200 feet O.D. Above this 

 level the country is deeply covered with peat, and all else is 

 obscured. 



An examination of the drift from about 700 feet upwards reveals
