Wright and Muff — Pre-glacial Raised Beach. 291 



In the bay, three-quarters of a mile east of the Coastguard 

 Station, the pre-glacial cliff recedes from the modern cliff, and 

 consequently the platform scarcely rises above high- water mark of 

 spring-tides. Just west of the small stream which enters the bay, 

 40 feet of head overlies 2 to 3 feet of sand and coarse gravel. 

 The head contains loamy streaks and irregular bands of blown sand. 



A few yards the other side of the stream, the following section 



was obtained : —

Cemented sand and gravel, . . . . 1-2 



Platform 6 feet above high- water mark of ordinary spring-tides. 



The eastern side of the bay runs almost at right angles to the 

 strike of the rocks, and the pre-glacial shore is cut up by several 

 gullies eroded along the softer beds. Sand and gravel, or sand 

 with layers of pebbles from 2 to 6 feet thick, fills up the gullies, 

 and is overlain by 20 to 30 feet of head. 



After rounding the headland, and for about half a mile to the 

 east, the head in many places has been cleared off, and the pre- 

 glacial cliff exposed. It slopes steeply towards the shore ; and at its 

 foot, there is generally some trace of the water- worn rock-platform. 



East of the large stream in Ballylanders townland, 20 feet 

 of red sandstone head, with some yellowish loam at its base, rests 

 on the platform. 



About fifty yards round the next point, the section seen in the 



cliffs is as under : —
