cut into during the readjustment of curves when the present 

 beach was built. The land behind the shore is overlaid by a thin 

 sheet of till. It slopes gently bayward, and the inner margin of 

 the lagoon gradually merges into the mainland. Both on the 

 east and west there is a low cliff above the beach having a height 

 of about 2 feet. The cliff and beach that must have existed 

 behind the lagoon have long since disappeared. The gravel bars 

 on the sides rise about 3 feet above water level. That on the 

 east is a little larger, and consists of coarser material than the 

 one on the west. Almost all the gravel composing the bars is 

 derived from the adjacent bed-rock — a nodular shaly limestone 

 of Trenton age. 



5. Pleasant Poi?it spit. — This is the largest and the most inter- 

 esting of all the forelands on the bay. The general form of the 

 foreland is shown by the accompanying plan. The material of 

 which it is built is almost wholly gravel. The eastern side con- 

 sists of very coarse shingle containing numerous flat plates of all 

 sizes up to three or four pounds in weight. Thevvest arm, on the 

 other hand, consists chiefly of smaller rounded pebbles, rarely 

 over an inch in diameter, and there is also a certain amount of 

 fine gravel and sand. 



To the west of the foreland there is a shore cliff about 20 feet 

 in height, of which at least the upper 5 feet are glacial till. The 

 base of the cliff is shaly limestone, and the width of the normal 

 beach is between 6 and 10 feet. It is strewn with coarse cobbles, 

 there being very little fine material such as is found on the arm 

 of the spit a few yards away. The old cliff runs behind the spit ; 

 twice it changes its direction, recording significant changes in the 

 growth of the spit. Its height at the base of the eastern arm is 

 only about 5 feet. It continues as a low bluff for some distance 

 to the southeast. The drift varies in thickness, but near the spit 

 its thickness is about 2 feet. 



The original foreland so far as it can be traced, lay a little 

 farther to the west than the present one, and was very similar in 

 shape and size to that near Prinyer Cove. At the present time 

 there are seven distinct beaches. Counting east from the inner 

 triangular lagoon, the first three of the beach mounds or ridges each
