(p. 48.) — " The Saltee Islands. — These islands lie to the south of 

 the mainland, and are connected with it by a bar or ridge that is 

 partially submerged and partially tidal, the latter portion being^ 

 called St. Patrick's Bridge. On the east of St. Patrick's Bridge are 

 some large blocks, the residue of the drift that has been cut away by 

 the sea, the largest being called ' St. Patrick's boat,' from a legend 

 connected with it. It is a remarkably large erratic." 



(p. 50.) — "The bar of ^olian Drift that separates the Lady's 

 Island lagoon from the open sea is, in places, swept over during 

 storms and high tides. Outside the bar, during storms, the sea tears 

 up large pieces of sandy, clay peat, similar to that at the bottom of 

 the lake. On the east coast, between Crossfintan Point and Carna 

 House, there is a low ridge of ^olian Drift, while north of Carna 

 House is a submarine peat extending below low-water mark."

(p. 22.) — '■'■Raised Sea-Coast. — All along the coast of the counties 

 of Wicklow and Wexford, the evidences of a recent rise in the 

 sea bed and adjoining coast are remarkably clear. These consist in 

 the occurrence of terraces and flats formed of silt, sand, and shelly 

 gravel, rising a few feet above the high- water line, and bounded inland 

 by cliffs or abrupt banks (according to the nature of the material and 

 form of the ground), which originally constituted the sea margin at 

 the time when the terraces and flats were submerged. The actual 

 extent of rise of the coast and sea-bed is uncertain ; but the old sea- 

 bed generally lies from six to twelve feet above the highest tides, 

 The level is often increased by hillocks or dunes of blown sand which 

 have been thrown up by the winds, as is the case in Brittas Bay, 

 Arklow Bay, and other protected inlets. In the district contained in 

 Sheet 139, examples of the raised coast are to be observed in the 

 bays lying between the headlands, and in a direction from north to 

 south they occur — 



"(1) In Brittas Bay, between the Castle Eock of Ballynacarrig 



(Sheet 130) and Mizen Head. 

 " (2) Between Mizen Head and the coast cliffs of Kilbride.
