manus Bay on the north and Eoaring-water Bay on the south, 

 terminating in Mizen Head, the glacial striae are very generally 

 to be observed, their usual direction being W.N.W. and E.S.E. 

 Some of the finest examples of glacial furrowing and polishing in the 

 whole South of Ireland appear on the east shoulder of Mount Ga- 

 briel, at an elevation of close on lOUO feet above the sea in the gap 

 where the road to Skull from Bantry passes ; the groovings, which 

 are some of them more than 18 inches in depth, mark the preci- 

 pitous face of the hill with polished, architectural-looking flutings 

 and mouldings. It is very probable that glacial scratches occur on 

 the very summit of the mountain, which is 1339 feet above the sea. 



Bosses of rock, beautifully rounded and polished by glacial action 

 are exposed over all the district around Ballydehob and Skull ; and 

 at the mouths of the rocky glens there the remains of the moraines 

 are distinctly to be seen. 



On the northern flank of the Coraeragh mountains, in the county 

 Waterford, and to the E. of the village of Ballymacarbury, there

is a narrow rocky glen facing to the which is the most 



clear example of the bed of an ancient glacier that I know of in 

 tlie South of Ireland. The mouth of this glen is blocked up by a 

 series of the most perfect moraines, now cut through by the small 

 stream issuing from the gorge.
