III. CHAPPAQIJIDICK ISLAND. 



i. General Description. 



Chappaquidick Island, so-called, forms the eastern ex- 

 tremity of Martha's Vineyard, with which it is occasionally 

 connected, but from which it is usually separated, according 

 to the condition of the narrow isthmus-like beach which forms 

 the barrier between Katama Bay and the Atlantic Ocean. 

 During a larger part of the time there is an opening some- 

 where in this beach, but its position constantly shifts and at 

 times it becomes closed and remains so for brief periods, or 

 at others two openings may occur contemporaneously. At 

 the date of my visit, last September, there was a single open- 

 ing, close to Wasque Point, as shown in Fig. i on next page. 



In N. S. Shaler's " Report on the Geology of Martha's 

 Vineyard"* may be found a discussion of this phenomenon 

 and also a report by Henry C. Whitney, with a map, de- 

 scribing the recession of the beach and the changes in posi- 

 tion of the opening, based upon surveys made in connection
