46 THE DENUDANTS, OB CARVERS OF 



The north part of the north-west coast of Inish- 

 more, as before mentioned, is a perpendicular cliff 

 which either rises sheer up from the sea level, or has 

 at its base a< few steps. 



The vertical .cliff seems to be caused, in a great 

 measure, by vertical master joints, some of which cut 

 through all the visible beds, while others only reach 

 the shale beds, that are found in these limestones at 

 the base of some of the inland terraces or steps, and 

 also as subordinate beds in the limestones that form 

 the south-west sea-cliffs. In the former case the 

 cliffs are perpendicular down to the sea, while in 

 the latter there are steps or sea-terraces at the 

 base. 



Beginning at the N.W. to examine these cliffs, 

 the observer will find that immediately E. of 

 Mweeleenareeava there are master joints ranging N. 

 70 W., which extend down to the shale beds which 

 inland lie under terrace No. 5 ; and as the shales at 

 this place meet the sea at about half neap tide, there 

 is a perpendicular cliff above this level, while below 

 it there are steps. 



From this for nearly a mile towards the S.E., 

 the master joints bear E. and W., or a few points on 

 either side of that line, and as they extend below 

 low water level of neap tides the cliffs are perpen- 

 dicular. S.E. of Polladoo there are four sets of 

 steps at the base of the cliff, and the note made on
