     In Prince Edward Island, as in other parts of 
     
     North America, the rocks which form the basis of 
     
     the country are covered with a deposit of sand clay 
     
     and fragments of stone, indicating the action, at some 
     
     former period, of powerful currents ofwater,and pro~ T 
     
     bably of other agents. In the neighbourhood of‘ 
     
     Charlottetown, this deposit consists of red coloured 
     
     sand and clay, derived from the abrasion of the sub- 
     
     jacent rocks, intermixed with fragments of red sand 
     
     stone usually small. Westward of Charlottetown, 
     
     it contains in some places great numbers of rounded 
     
     and water-worn masses ofthis stone, and wherever 
     
     I had an opportunity ofexamining it, also a few frag- 
     
     ments of coarse grey sand stone, differing from any 
     
    
   
   
    
     which appeared in place. 
     
    
   
   
    
     Scattered over the surtace at long intervals, a few 
     
     ofthese erratic blocks,-tho’ rare, appear to be rather 
     
     uniformly dispersed, and some of them are oflarge 
     
     dimensions. Their small number in the vicinity of 
     
     Charlottetown, is rather remarkable, as l have been 
     
     informed that they are very numerous in the north- 
     
     ern parts of the Island, and on the opposite shore 
     
     ofNova Scotia they are extremely abundant. As 
     
     these blocks belong to formations much more ancient 
     
     than those found in P. E. Island, and not occurring 
     
     in places within great distance ot it, they afford a 
     
     striking indication of the power and extent ofthe last 
     
     great revolution to which the earth has been sub— 
     
    
   
   
    
     jected. 
     
    
   
   
    
       
     
    
   
   
    
     THIS closes the Geological “ Notes” of1842, and we will now 
     
     proceed with that part of Dr. Gesner’s report that relates to
