occur on the Scottish shores would have been traceable 

 along the rocky coasts of Wales and Ireland. As a matter 

 of fact, the lowest or 25-feet beach descends to lower and 

 lower levels along the east coast of Ireland, and coincides 

 with the present level of the sea in the neighbourhood of 

 Dublin. 



We may therefore conclude that though the buried 

 forests of Scotland grew, like those of England, during a 

 period of subsidence, either this subsidence did not last 

 so long in the former country as it did in England, but 

 was succeeded by a reverse movement while the south of 

 England was still sinking, or else that after the subsidence 

 had affected both countries to the same extent, an upheaval 

 took place in Scotland while the greater part of England 

 and Ireland remained in a stationary condition. It is only 

 on one of these two suppositions that the phenomena of 

 raised beaches and buried forests in England, Scotland, 

 and Ireland can be satisfactorily accounted for.
