Introduction. 



At the meeting of the Academy on October 19, 1896, I gave 

 an account of the geology of Block Island, prepared from in- 

 vestigations personally made during the summer of that year, 

 together with all references to the subject on the part of others 

 which I had been able to gather.^ To this account I would 

 respectfully refer, in order to avoid reiteration, for information 

 regarding the general geologic conditions which prevail and the 

 opinions which have been expressed in relation to them, La^i 

 summer I again visited the island, for the special purpose c:
