CORRYS WITH OR WITHOUT LAKE-BASINS. 129 



corrys, while all are being similarly formed, although 

 many are very diminutive. This coast is dissimilar to 

 the rest of that of the County Galway, as the cliffs 

 range from 100 to 400 feet high, while it is not open 

 to the full force of the Atlantic Ocean, having nearly a 

 northern aspect, and being subject to a cross current 

 due to the tides meeting the stream flowing into and 

 out of the landlocked bays known by the general 

 name of Ballynakill Harbour ; and, as before pointed 

 out, the sea acts more vigorously in confined places 

 than on the open seaboard. 



In about half-a-mile of this coast there are seven 

 cooses now being excavated or scooped out; these 

 were carefully examined, and the details noted. 



In Goose No. 1 there are four breaks in the strata 

 that have facilitated its excavation a main-break, 

 that seems to be also a fault (a, fig. 9, PL I.), along 

 which the sea at first worked ; it afterwards came 

 to the cross breaks (, , and Q, when it began to 

 widen out the interior of the coose. 



Coose No. 2. The sea worked in along two breaks 

 until it came to two cross breaks, between which the 

 rock is being excavated. 



Coose No. 3. Here there are two breaks (a and , 

 fig. 10, PL I.) diverging from the coast- line along 

 which the sea could work, and subsequently exca- 

 vate out the intervening rock. The work has now
