GENERAL FEATUEES OF THE REGION 



Location 



The Penobscot Bay region in Maine is situated on the coast 

 about midway between the eastern and western boundaries 

 of the state. Strictly speaking, the term, ''Penobscot Bay", 

 should be used only for that portion of the region lying at 

 the mouth of the Penobscot River, In general, however, the 

 name is applied to all the territory between the island of 

 Mount Desert on the east and Rockland on the west. This 

 area lies between meridians G8° 25' and 60° 2' west longitude 

 and parallels 44° and 44° 20' north latitude. It contains 

 approximately 650 square miles, about half of which is water. 

 Of the land, about one-quarter belongs to the mainland and 

 the remainder to islands. The latter are very numerous and 

 vary in size from the smallest ledges to some which contain 

 as many as twenty-five square miles. (See- map.) 



It is with the eastern part of this region alone that we shall 

 be concerned. This embraces the townships of Brooklin, on 

 the mainland, and Deer Isle, Stonington, Swans Island, and
