1920. Callag Ay; .—Glacial Deposits of Watervilh. 85 



The Cummerai^h River after passing tlirough the lake 

 has cut its way to the sea through the lowest part of the 

 moraine and is now clown to bed-rov-rk. From the lake to 

 the sea, a distance of about 600 yards, it is locally named 

 the Waterville River and is joined just before its debouch- 

 ment b}^ the Finnyglass River. It now runs in a well- 

 defined channel, controlled in places by artificial banks. 

 On the south side a long spit of sand and shingle runs out 

 into the bay with the ruins of the high glacial cliff at the 

 back of it. 



The delta of the old river before the building of the 

 bridges is indicated on the map. The ruined piers of the 

 most ancient of the bridges still remain in situ. Before 

 the building of this bridge all crossings were by the ford. 

 In 1826 the present bridge was built. The old road over 

 the original bridge passed through the grounds of Water- 

 ville House and continued quite one hundred yards seaward 

 of the present " Main Street " of Waterville, joining the 

 present road nearer Spunkane. 



This " Main Street is 28 feet above H. W. S. T., 

 just in front of the Bay View Hotel. The road from the 

 village to the golf links along the shore is about two feet 

 from the edge of the cliffs. It is only a matter of a year 

 or two before it will disappear and a new road be necessary, 

 so fast does the moraine wear away. 



The houses at Poolearagh, now at the edge of the beach, 

 were, in the lifetime of one of the present inhabitants, so far 

 from the sea that hurley and football were played in the 

 seaward fields. 



From the shore in front of the Bay View Hotel the 

 moraine rises in hummocky knolls and ridges to about 

 80 feet and then descends in a gentle slope to the lake. 

 The deposition of this moraine created Lough Currane, 

 which before the Great Ice Age was an inlet of the sea. 

 The channel which connected this inlet with Ballinskelligs 

 Bay did not coincide with the present outlet of the lake 

 but lay further north, as is apparent from a consideration 

 of the exposures of rock on the foreshore and elsewhere. 

 If the drifts were now removed the sea would enter the 

 basin of the lake along a line crossing the Main vStreet at
