Egg Harbor River, near Mays Lauding, and believes it to be the same 
as that at the Absecon wells. Other outcrops are at Long Branch and 
Bridgeton. Its dip was found to be 6 feet per mile. From a careful 
study of the diatoms and the relations of the beds Mr. Woolman con- 
siders the clay and gravels at 58 to 63 feet and 72 to 75 feet in the 
Atlantic City wells to belong to this series. They were also found in 
the well at Fifields at 84 feet, and in other wells along the southern 
shore of New Jersey. 
Asbury Park, Monmouth County. — The first well is situated on the 
land of Mr. Uriah White, 3,276 feet northeast from the Ocean Grove 
well. The materials penetrated were the same in this well as in that 
at Ocean Grove. The layer of shells containing Terebratula harlani, 
which is near the top of the Middle Marl bed, was found at 270 feet, 
and continued 7 feet. It has a considerable body of greensand below 
it. At 365 feet there were sands containing fragments of Belemnitella 
mucronatdj Exogyra costata, Gryphcea convexa, and Ostrea falcata of the 
Lower Marl bed or Navesink formation. The water is in sands at the 
base of this formation at a depth of 383 feet. The capacity of the well 
proved to be about 95,000 gallons a day. 
Another well was bored in 1884 to a depth of 448 feet, to a sand bed 
at the top of the Matawan formation, which yields about 20 gallons a 
minute. 1 
In the past few years several deeper wells have been sunk to obtain 
increased water supplies and discovered very important water-bearing 
beds. Three borings attained depths of 1,045, 1,130, and 1,350 feet 
respectively. The deepest of these was damaged by an accident and 
abandoned, but the other two yield nearly 1,500,000 gallons of water 
per day by the air-lift process. The water contains considerable iron, 
but aeration and filtration render it satisfactory for use. 
Mr. Woolman 2 has recently given a detailed account of the forma- 
tions penetrated by these deep borings, which throws much interesting 
light on the geology. Below the Lower Marl at 380 feet are alternating 
clays and sands mainly of light color. Gray sand with water was 
reported at 380 to 430 feet, several water-bearing sands from 500 to 
630 feet, glaueonitic clays 630 to 954 feet, water-bearing fine sands 
954 to 1,000 feet, and coarse gray sands with the main water supply at 
1,083 to 1,135 feet. Below 1,135 feet were dark clays and sandy clays 
in whicli no water was obtained. Molluscan remains reported at 1,195 
feet included an Exogyra, which would indicate Matawan beds. If the 
depth is correct, this would indicate an unlooked-for expansion of the 
Matawan formation to a thickness of at least 800 feet — 400 to 1,200 feet 
in the boring — and it is the opinion of Mr. Woolman that it extends to 
the bottom of the deepest boring.
