(p. 208.) — " Fenit Island. — Towards the north point of Fenit are 

 several sunken rocks, and also one above water called the Rose. This 

 island at low water is contiguous to the mainland ; but in all former 

 charts and maps is placed at a great distance from the shore. 



'■'■ Ballyheigli Bay and Strand. — The land towards the bottom of 

 this bay is very flat, soft, and boggy, and hath no other defence but 

 the above-mentioned sandbanks from the fury of the ocean, which 

 almost every winter breaks through them in many places ; and, 

 therefore, a considerable tract of this part of the country will in a few 

 years (from 1756) be probably overflown. The neighbouring inhabi- 

 tants show rocks visible in this bay only at low water, which they 

 say are the remains of an island that was formerly the burial-place 

 of the family of Cantillon, who were the ancient proprietors of 

 Bally heigh. 



" It is easy to see that if the land were depressed some 2400 feet, 

 the sea would then surround the mountain tops, transforming them in 

 time into islands like the Skelligs, and that if, as the ground arose from 

 the sea, the elevating action occasionally ceased, or went on very 

 slowly, the mountain clifis and steeper declivities would be formed 

 by an action precisely similar to that which is acting on the present 

 coast." 



(p. 18.) — "Purple grits and slates, with a general strike of about 

 east 25° (?) are seen on the mountain slopes on both sides of the road, 

 from Cahersiveen to Coomnahincha and Coonanna Harbour ; and the 

 continuation of the ridge from this to Doulus Head exposes along the 

 line of sea- cliffs to the north and round Doulus Head to Laght Point, 

 a series of remarkable contortions in reddish purple girths, amongst 

 which are some slate beds. Some of these contortions are seen in the 

 annexed sketch of Doulus Head from the west. A north and south 

 fissure crosses the headland where the figures 10 to 70 are engraved 

 upon the map between the points marked 355 and 921. At the south 

 end of this, and running inward along it, is the Doulus Lane. Due 

 west of Glanlean (iu Valencia Island) is the hill called Geokaun, 

 rising to the height of 888 feet above the sea, and presenting to the 

 north-west the bold sea-cliffs of Fogher, which are some of the 

 finest of the kind in the whole district, being nearly 700 feet in 

 height." 



(p. 22). — "In the cliff to the south of Dromgoui', which is the 

 highest sea-cliff in this district, being 867 feet above the level of the
