the sea, there is a mass of rock that looks like a greenstone dyke. 

 Puffin's Island is chiefly composed of purple slates, wliich are well 

 exhibited in the cliffs all round it." 



(p. 33.) — ** The surface of the country round Sneem is stated to 

 have been once a smooth turf bog. Subsequently to the deposition of 

 the drift and accumulation of the bogs, two actions, one of elevation, 

 and the other of depression, seem to have occurred in parts of the 

 district, if not over the -whole of it. Owing to the latter action, the 

 sea at Reenagappal, in Valencia Harbour, flows at every tide over 

 part of the bog which so extensively covers the mainland. This 

 could not have been formed in the situation it now occupies beneath 

 the sand at low-water mark, but must have grown above high- water 

 mark, thereby showing a depression of at least 25 feet to have taken 

 place. A portion of the boggy flat at the north-west corner of the 

 map, as has been already stated, is laid under water by the higher 

 tides." 



Memoir Geological Survey of Ireland (Sheets 197 and 198 and 

 south-east part of 191). The district described is the termination of 

 the promontory between Bantry and Kenmare Bays, from Kilmakiloge 

 Harbour, and the eastern part of Bear Island to Dursey Head. 



The mountainous ridge that separates Bantry Bay from Kenmare 

 Bay (or river, as it is often called), has its loftiest eminences to the 

 east of this district ; its crest, however, still retains an altitude 

 of over 1900 feet, south of Kilmakiloge Harbour, forming a rather 

 flat -topped ridge, from which proceed broken lateral spurs and deep 

 valleys, with sides that show many cliffs and precipices of bare rock. 

 About one and a half miles north of Castletown Bearhaven the crest 

 of the ridge sinks rather suddenly down to a level of 300 feet above 

 the sea, forming an open pass between the hills already spoken of and 

 the Mirkish and Knockoura Mountains, which rise to 1272 feet and 

 1610 feet respectively. The ridge is then continued to the west, 

 gradually sinking down to Dursey Sound, which is another pass (the 

 floor of which is now below the level of the sea), between the main- 

 land and Dursey Island, the summit of which is 825 feet above the 

 sea. 



(p. 6.) — "It would be difficult to describe and almost impossible 

 to exaggerate the picturesque beauty of mxxch of this high rocky 

 ground, commanding views over Bantry Bay, on the south, and the 

 still more lovely, Kenmare Eiver, to the north, backed by the Kerry
