T)U NOYER— Olf THE SOUTH OE lEELAND.

The extreme measurement of the moraines would be about half a 

 mile from east to west, with a widfch in their central part of about a 

 quarter of a mile. In many places the rocks in this glen are beauti- 

 fully polished, rounded, furrowed, and striated. 



To the spectator standing on the mountain-side to the S.E. of this 

 glen, and looking down on it, the view is most striking, and the 

 imagination need not be very vivid to complete the picture by the ad- 

 dition of the glacier with the snow-covered mountains beyond. 



Over the wide mountainous promontory formed by the Bay of 

 Kenmare on the north, and Bantry Bay on the south, all the rock 

 surfaces where freshly exposed from beneath either bog or Drift, are 

 more more or less rounded and striated ; in some glens these striae 

 are observed at the height of 1100 feet above the sea, the direction 

 varying from N. and S. to N. W. and S.E., and sometimes from N.N.E. 

 to S.S.W. 



The mountains to the north and west of Dunmanway in the county 

 Cork afford some very striking evidences of glacial action. Most of 

 the rock surfaces being observed to be polished and scratched in the 

 direction of N.N.W. and S.S.E., the striae being thin at the former 

 and blunt to the latter point of the compass. The highest elevation 

 at which I have observed these glacial marks in this district is 975 

 feet, and the lowest 200 feet above the sea, thus proving that during 

 the whole period required to elevate the ground 775 feet, or the 

 difference between 975 and 200 feet, the conditions of the sea and 

 climate were permanent and favourable to the formation and drifting 

 of ice masses. 



Over the summit of Coolsnaghtig Hill, which is| close to Dunman- 

 way and 975 feet above the sea, and at its eastern end, called Mount 

 Gunnery, 757 feet high, the glacial striae are remarkably well de- 

 veloped, and many perched boulders are scattered over both moun- 

 tains ; one large block, called " Maragh," is close to the very summit 

 of the latter hill. All the blunt edges of the sandstone rocks over 

 both these mountains when presented to the JST.N.W. are rounded 

 and striated, the vertical faces of the beds being marked with hori- 

 zontal striae. Over the whole of the Dunmanway district there are 

 very many perched boulders, and some of them of enormous size ; one, 

 called "White Horse E-ock," is close to the village, and there are seve- 

 ral others near to it. The largest erratic block occurs at the distance 

 of three miles to the westward of Dunmanway, in a hollow on the west- 

 ern flank of the mountains over Ship Lough ; it is called " Ship Eock "
