and the sea yearly causes great destruction of the 

 rock. This cliff, which is about 100 feet high, is 

 undercut at the base. At Bensheefrontee, the point 

 a little N.W. of Doocaher, the " block beach " sets 

 in and extends to the S.E. point of the island, having 

 only five small breaks in it ; three at the cooses or 

 small bays in the vicinity of Doocaher, one at the 

 coose called Doughatna, and one about 40 yards wide 

 at the Glassen rock in all of which places the base 

 of the cliff is undercut, while that part which is sur- 

 mounted by the " block beach " is stepped. However, 

 although it is undercut and forms a cave at Doughatna, 

 yet below the cave there are six very low steps. The 

 highest part of the cliff on which this beach occurs 

 is in the vicinity of Doocaher, and about 100 feet 

 above the sea level ; while the lowest part, a quarter 

 of a mile west of the Glassen rock, is about 35 feet. 

 The S.E. point of the island, where the beach ends, 

 may be 100 feet high. 



These steps at the base of the cliffs are usually from 

 four to seven in number, seemingly having been cut, 

 one by low water of spring tides, another by low 

 water of neap tides, another by high water of neap 

 tides, another by high water of spring tides, with one 

 or two intermediate steps when the limestones are 

 thin bedded, and the systems of joints do not extend 

 through more than one or two beds. However, in 

 places they are modified by master joints, along which
