72-78 white sand. 
78-83 large coarse gravel. 
83-85 white sand, with water, which rises to within 1| inches of the 
surface. 
85-89 gravel and sand. 
89-90 white clay. 
90-98 large gravel, with water, which rises to within 34 feet of the 
surface. 
98-104 gravel, clay, and sand. 
104-112 soft rock. 
112 hard rock, in which boring was discontinued. 
Cape May City, Cape May Comity. — There were seven 8-inch wells 
bored here to depths varying from 87 to 92 feet. They tap a stratum of 
fine, fresh water, and yield about 75 gallons per minute. Driven wells 
to from 25 to 30 feet yield from 7 to 10 gallons per minute. 1 
Cape May Point, Cape May County. — A well at this locality found a 
fair supply of water at 320 to 360 feet, in sands containing thin beds of 
clay and broken shells. The boring was deepened in 1890, and Mr. 
Woolman found diatom remains in materials from 45G feet in this 
well. 2 
Another well sunk to 224 feet obtained salt water. 
Cinnaminson, Burlington County. — A 6-inch well bored by A. 0. Wood 
a quarter of a mile east of the post-office passed through the following 
strata: 3 
Feet. 
0-6 earth. 
6-7 shells. 
7-27 yellow sand. 
27-30 line white gravel. 
30-32 ...... yellow clay. 
32-42 whitish sand. 
42-46 coarse white gravel. 
The well yields 400 to 500 gallons per minute, and the water has a 
temperature of 52°. 
The water appears to be from the basal Matawan horizon. 
Clayton, Gloucester County. — Three 2-inch and three 3-inch wells have 
been bored at this place. They all found water in a coarse gravel at 
80 to 105 feet from the surface, of which the elevation is about 140 feet. 
The water rises to within 21 feet of the surface, and each well has 
yielded 150 gallons per minute without being lowered. The water is 
thought to be in superficial sands and gravels, probably not far from 
Miocene (Chesapeake) clays. 4 A series of four wells for the water com- 
pany, reported by Mr. Woolman in 1895, 5 range in depth from 80 to 93 
feet. Miocene blue clay is reported at 105 feet.
