The Irish Naturalist, September, 



Bay View Hotel. The lake is in places nearly loo feet 

 deep, so that its bottom is well below sea-level. 



It is clear that when first formed behind the barrier of 

 moraine and before the Waterville River had time to cut 

 its channel, which is half a mile long, down to the present 

 level, the lake surface must have stood considerably higher 

 than it does to-day. From just beyond Beenbane one 

 can see the well-defined shores formed at this period of the 

 lake's history. It was then much more extensive and the 

 upper waters were near the level of the holly wood above 

 Glen Moor school. 



The Cummeragh River rising in a chain of beautiful lakes, 

 cuts through another moraine near Cahersavane and 

 Dromkeare Bridges, before entering Lough Currane. 



Lough Dreenaun is the fast-filling-up renniant of a large 

 shallow lake lying in a hollow caused by the ice which has 

 left a small terminal moraine at Baslikan. The effluent 

 from the lake has cut through the moraine where the 

 bridge crosses the river. Fine sections are to be seen from 

 the banks below the bridge. . There are two distinct layers 

 of Boulder-clay as on the shore, separated by a line of washed 

 stones. Most of the former bed of the lake is peat -covered 

 and cultivated. 



The sea beaches near Waterville are strewn with boulders 

 of all sizes, cuboidal, angular and striated, derived from the 

 glacial drift. They have not travelled far, and there are 

 no really foreign stones amongst them, a detailed search 

 revealed nothing that might not be derived from the local 

 Old Red Sandstone series. 



Through the courtesy of Mr. Hughes, Superintendent 

 of the Commercial Cable Company, I obtained the details 

 of the boring of a well at a spot marked " Windmill " in 

 the C.C. Co. grounds, which is about 85 feet above sea 

 level ; this shows the depth of the moraine at that spot to 

 be 56 feet from the present land surface — see section ; 

 sections of the core are still lying around the well ; the rock 

 is all Glengariff grit. In one section I found traces of 

 a copper vein. The following is the journal of this bore : —
