Point, Long Island, and the Elizabeth Islands. The strata 

 are not contorted as they are in the southern or older branch ; 

 water-assorted material preponderates over glacial till and 

 bowlders are relatively not abundant. 



At the time of my visit there was no exposure of any basal 

 clays in the moraine or any indications of any which might 

 be considered as older than those which were evidently 

 deposited as morainal or modified drift material and I failed 

 to find a vestige of any rock or a trace of any fossil which 

 could be even provisionally referred to the Cretaceous forma- 

 tion, although the face and talus slopes of the bluffs in the 

 vicinity of the lighthouse were carefully searched for several 

 miles in either direction. 



I was led to hope that this locality, if any, would give 

 some evidences or indications of the former existence of 

 Cretaceous strata in the vicinity for the reason that Upham 

 mentions (/. c, p. 560) having found lignite and "clay 

 bowlders," which latter he describes as " changed to a brown 

 color for a depth of half an inch from the outside, due to 

 oxidation of the iron," — a description which quite accurately 

 fits the material in which Cretaceous molluscs and plant re- 

 mains occur so abundantly in connection with the moraine on 

 Long Island, Block Island, Martha's Vineyard and else- 

 where. Further than this, in the same article, he also notes 

 the discovery of "an Anomia similar to A. tcllinoides Mor- 

 ton, of the Cretaceous in New Jersey, Alabama and Missis- 

 sippi." 



The above memoranda were of course exceedingly meager 

 and unsatisfactory evidence of the presence of Cretaceous 

 material, and my failure either to verify my interpretation of 

 the facts or to add any new ones was perhaps to be expected. 

 We may say, therefore, so far as the evidence now in our pos- 

 session is concerned, that no satisfactory identification of Cre- 

 taceous material has yet been made from any locality east of 

 Buzzard's Bay or Martha's Vineyard, for such identification is 

 also lacking in regard to any specimens reported from the 

 island of Nantucket.
