and that between the vicinity of Quebec city and the United 

 States boundary line as the Notre Dame Hills. The district 

 lying within the I^otre Dame hills is commonly designated as 

 the " Eastern Townships," the geological structure of which 

 has furnished the theme of much well-known discussion 

 during the past forty years. This has been chiefly connected 

 with the question of the Quebec Group. "^
