92 ARTESIAN WELLS ON THE ATLANTIC COAST. [bull. 138. 
depth of 280 feet. It is located on a bank facing Barnegat Bay, at 
about 10 feet above tide level. The record was as follows: 
Feet, 
0-10 gravel and Band. 
10-30 brownish clay. 
30-70 blue clay. 
70-280 alternations of black mud and black sand, changing near the 
bottom to gravel and white sand. 
At 70 feet there was a small flow of water which rose 6 or 8 feet 
above the surface, and at 137 feet there was another small flow which 
rose but 2 feet above the surface. An examination of the sands by 
Mr. Woolman revealed the presence of diatoms of the great diatom 
clay bed, and this bed is thought by Mr. Woolman 1 to comprise the 
strata from 10 or certainly from 30 feet to 255 feet in this well, a 
thickness of over 200 feet. The lower 25 feet are thought to represent 
the water-bearing stratum found below the great diatom bed at 700 feet 
at Atlantic City. 
Wenonah, Gloucester County. — A well at the hotel at this place obtains 
a supply of 40 gallons a minute from between 320 and 341 feet. The 
following section is given : 
Feet, 
0-32 loam. 
32-52 gravel. 
52-245 black clay, with Exogyra costata at 115 feet. 
245-280 gravel in streaks. 
280-318 lighter-colored clay. 
318-341 coarse sand and gravel with water. 
The horizon is thought to be the same as the one at Sewell at 305 to 
420 feet, or at the base of the Matawan formation. The dip indicated 
is 38 feet per mile. 2 
Two wells were bored in 1894 to supply the waterworks at Wenonah. 3 
They are located about one-half mile northwest of the hotel well and 
on ground elevated only about 10 feet above tide level. Their depth is 
196 feet and they obtain water from a bluish-gray coarse sand which 
is thought to be the equivalent of the gravel in streaks reported at 
from 245 to 280 feet in the hotel well. 
West Creek, Cape May County. — A well for Kirby & Smith is situated 
on the marsh within 300 feet of the bay shore. The following record 
is given : 
Feet. 
0-18 salt mud. 
18-21 blue clay. 
21-24 yellow clay. 
24-27 pink clay. 
27-72 quicksand.
