Black Point in Seaconnet river and at the “ Paradise ” ridges. 
The recess between Easton’s Point and Sachuest Point was thus 
formed ; that between the Cliffs and Easton’s Point, and also the 
hollow occupied by Easton’s Pond, Brenton’s Cove, and the de¬ 
pression between the chloritic slates and the flinty slates on the 
Neck, the passage between Conanicut and Fort Adams and the 
harbor, Mackerel cove in Conanicut, and the passages on either 
side of Dutch Island, all are due to the same causes. 
A few things remain to be noticed. As the ice sheet thawed it 
deposited its load of clay, sand and boulders, all over our region, but 
very unequally. In this vicinity the morainal matter is not very 
thick, but near Providence it forms considerable hills and plateaus. 
But we received our share of the boulders as every builder, far¬ 
mer, gardener or pedestrian knows. Much of this morainal mat¬ 
ter was deposited in the sea, and this, together with what has since 
been carried thither by streams or formed by the wear and tear of 
the waves, the sea has, in part at least, thrown back upon the 
shore in the form of sand bars and beaches. Then the wind com¬ 
ing to the aid of the waves piled up the sand in drifts back of the 
beaches, damming up the outlets to small streams and forming 
ponds which are gradually transformed into marshes. In this 
way the recesses in the coast are filled out and the shore is be¬ 
coming more rounded in outline. 
As we study a map of our bay with the knowledge of these 
geological facts, its features begin to brighten with a' significance, 
which will materially enhance our enjoyment of the picturesque 
scenery which surrounds us.
