The Belemnitella mucronata is characteristic of the Lower Marl bed 
and the Terebratula harlani in the Middle Marl bed. The dip indi- 
cated by the Lower Marl bed in this well is 36.6 feet per mile from Mid- 
dletown, and by the Middle Marl bed 37 feet from Big or Crawfords 
Hill. 1 
Other wells have been sunk which add to the supply. The water is 
from the basal beds of the Lower Marl, the same as at Asbury Park 
(at 383 feet), Spring Lake, and many other wells, as shown on the right- 
hand end of sections 1 and 5, PI. III. 
In 1894 a well was bored at Ocean City to a depth of 1,134 feet. 
A heavy bed of coarse white gravel and sand was found at 1,083 to 
1,130 feet, which yields a large water supply. The horizon is low in 
the Matawan formation, as in the deep wells at Asbury Park. A record 
from to 553 feet is given by Mr. Woolman in New Jersey report for 
1895. 2
