more rapid. Between St. Helen's and Greenore Point, the waste has 

 been 1 foot per annum. Between Greenore and Bally geary pier, 

 •25 foot, and between tbe pier and Rosetown about -50 foot. The 

 denudation here being greatest in the townland of Hill of the Sea, 

 •75 foot, 



(p. 17.) — " The new pier of Ballygeary exemplifies how easily, by 

 a well regulated system of groynes, the denudation of this coast 

 could be arrested. The pier was commenced in the spring of 1873, 

 and in 1875 a large accumulation of sand had collected along the 

 coast to the south-east, but especially in the vicinity of the pier 

 where now (1878) sand-dunes are forming. This accumulation forms 

 a foreshore that is gradually stopping the denudation of the clifi. 

 The cliff to the westward of the pier also now suffers less from 

 denudation. 



"From Rosslare coast-guard station (Rosehill) to Ballinesker 

 (Wexford ^i-), are the banks (Eosslare and the E,aven) that enclose 

 the lagoon of Wexford Harbour. They are composed of ^olian Drift, 

 and have been considerably altered, especially Rosslare since 1840. 

 Opposite White House, at the land or south end of Hosslare, the 

 coast line has moved westward or inland over 100 feet (3 feet per 

 annum). Opposite Eosslare House, about 75 feet (2 feet per annum), 

 and a mile and a quarter farther north, where the denudation is 

 greatest, about 203 feet or 5-74 per annum. From this point north- 

 wards, the denudation decreases to the Bull's Perch, where it is 

 50 feet (1-45 per annum), but to the north thereof it again rapidly 

 increases, being at 170 yards north of that point, 150 feet (about 

 4 feet per annum), the banks in places being breached, and the sea 

 passing through it during gales from the south-east. Further north 

 the bank originally had a very irregular outline, but now it has been 

 considerably added to inside, while outside in places it has been cut 

 away. The length of the bank has also increased northward. 

 When it was examined in 1876, the Dogger Bank, off the mouth of 

 "Wexford Harbour, was of considerable size, and in part an island. 

 This, however, has quite changed in the last two years, the island 

 having disappeared, and consequently the form of the northern portion 

 of the Eosslare has also changed." 



(p. 18.) — "The changes in the forms of the Eosslare and Eaven 

 Banks are in a great measure due to the intaking of the north and 

 south midlands in Wexford Harbour, as now the outflow of the 

 water is much less than formerly ; consequently the ' Flow tide ' 

 wave current from the south changed the form of the Dogger Bank
