About an eighth of a mile south of the Cemetery Shell-heap, 

 a thin deposit was discovered under the turf at the roadside. 

 It covered an area of only fifteen or sixteen square feet, and 

 yielded few specimens of interest. From it were taken frag- 

 ments of pottery and the remains of the following species of 

 animals : 



Phoca vitulina (Harbor Seal). Ostrea virginiana (Oyster). 



Acipenser sturio (Sturgeon). Venus mercenaria (Quahog). 



Terrapene Carolina (Box Tor- Mya arenaria (Long Clam), 



toise). Mytilus edulis (Mussel). 



A second small deposit, similar to that last described, was 

 found at the side of the lane immediately south of the ceme- 

 tery. It contained fragments of pottery and the remains of 

 four species of animals, viz : 



Lamnapunctata(MackerelShark) Pecten irradians (Scallop). 

 Mya arenaria (Long Clam). Helix alternata (Land-snail). 



The west bluff of the Island between Grace's Point and the 

 Gut is covered for the most part with sand dunes, some of 

 them grassed over, others unprotected and probably still being 

 drifted by the gales which sweep the Island. Those which are 

 protected by grass may possibly have retained their form and 

 position on the bluff for many years. This much at least is 

 certain : in many places under their surface, at depths varying 

 from a few inches to a foot and a half, small deposits of shells 

 and bones were found. With these animal remains were frag- 

 ments of pottery and a few stone scrapers or knives as well as 

 many refuse flakes of quartz and quartzite. From this locality 

 the following species were obtained :
