a second elevation as a 25ft, beach would indicate. The elevation 

 apparently took place very gradually until it reached 40ft. 



The continuation of the Roman Wall to, or below, low water mark 

 at Bowness ; the fact, that when the land stood at a lower level of 25 ft., 

 a considerable portion of Burgh Marsh would be under water, (and if this 

 had been the state of things when the Wall was constructed, instead of 

 crossing the marsh in a straight line between Burgh and Drumburgh, it 

 would have been carried further south, or have ended off at Drumburgh 

 altogether); the positions of the Roman camps at Maryport and Moresby ; 

 and other sources of information, afford grounds for arriving at the 

 conclusion that the elevation took place sometime prior to the Roman 

 occupation of this country. 



In conclusion, it was stated, that the latest movement on this coast, 

 however, was probably one of depression. The existence at St. Bees, of 

 the remains of an old forest lying between high and low water mark 

 would seem to point to a submergence of a more recent date than the 

 elevation of the raised beach. Whether this submergence, if a 

 submergence actually occurred, was also of pre-Roman age, there is not, 

 at present, sufficient evidence to show.
