graph Hill and Sagamore Head inthe Nantasket area. He 
has also called attention to the fact that, so long ago as the 
Revolutionary War, a fort was built on the top of Telegraph 
Hill, and a well was dug inside the fort of which the commander, 
Gen. Benjamin Lincoln, wrote as follows“: „There is a large fort 
on the E. Hill, in which there is a well sunk 90 feet, which 
commonly contains 80 odd feet of water. In digging the well, 
the workmen found many shells, smooth stones and different 
stratas of sand and clay similar to those on the beach adjoining 
to the hill. These shells and appearances were discovered 
from near the top of the ground to the bottom of the well." 
Of more than thirty species of shells collected by different 
observers from the till of the Boston Basin, Mr. Upham has, 
in a hasty examination, found but three — Venus mercenaria 
(the round clam or quahaug), Cyclocardia borealis, and Cliona 
sulphurea (a boring sponge)—in the section at the north end of 
Telegraph Hill; and traces of the round clam, which is by far 
the most abundant species in all the sections, in Sagamore 
Head. More recently, by careful searching, with the assistance 
of Mr. Н. D. Card, I have found the shells in the eastern 
searps of Point Allerton Great Hill, and Strawberry Hill; and 
have extended the list of fossils known to occur in the till of the 
Nantasket Peninsula to eleven species, as follows :—
