O'Reilly — On the Waste of the Goad of Ireland, iifc. 131 



(p. 202.) — " Some of the big waves or ' rollers ' that visit the 

 coast, on rare occasions are due to earthquakes." 



(p. 203.) — " At the Kish Bank, off Dublin Bay, an attempt was 

 made to erect a light-house on screw piles ; but it was given up, as 

 the flanges of the piles were broken by large blocks in the accumula- 

 tion of sand." 



(p. 207.) — "On no coast are groynes so necessary as that now 

 under consideration, especially in parts of Wexford and Dublin where 

 valuable land is yearly disappearing ; yet they have been erected 

 only in isolated spots." 



In the Memoir of the Geological Survey of Ireland, accompanying 

 sheets Nos. 158 and 159, including the district around Enniscorthy, 

 County Wexford, by G. H. Kinahan, m.k.i.a. (1882) the following 

 observations occur : — 



(p. 32.) — " Some of the newest accumulations are the estuarine 

 mudlmids of the north intake intheWexford lagoon. These mudlands are 

 described in the published memoir to accompany sheets 169, 170, &c. 

 To the north-east of this intake, at Curracloe and Ballinesker, both 

 inside and outside the .^olian Drift, which is the northern end of the 

 Raven Spit, is deep peat. That outside is cut when the tide is out, 

 and carried up above high-water mark, to be dried and made into 

 turf. Outside the marginal JEolian Drift hills in the Ram Channel, 

 peat has been dredged at the 4 fathom line."

 of the Black water there is the following section : —

At this place the denudation is excessive, the cliff being altogether 

 changed since Mr. Wyley made a sketch of it about thirty years ago 

 (1850-52); while since 1840 a strip of land about 175 feet wide has 

 disappeared or at a rate of over 4*25 feet per annum. 



From here south-west to Ballinesker (1-75 mile) the drift is
