 age a prominent member of the Geological Society of London, 

 spent a few days at this place, and published a most interesting 

 and graphic account of its topography and geology, in Silliman's

 Transactions of the Literary and Historical Society of Quebec,

 of Canada appeared in the Report of the Survey for that year. 

 Learning from these previous observers, that the locality is of 

 much geological interest, I determined in visiting it for a few 

 days in the past summer, to pick up such gleanings as my prede-
