In a third well, sunk in 1895, a good supply of fresh water is obtained 
in beds from 580 to 655 feet, a horizon which was not fully tested by the 
deep well. Details of beds penetrated are given by Mr. Woolman in 
New Jersey report for 1895. ! 
Winslow, Camden County. — A well bored many years ago for water 
for the gas works had the following record: 2 
Feet.

15-30 blue and black clay. 
30-125 glass sand, described as quicksand. 
125-160 Miocene clay, described as hard black clay.

This water has much excess of carbonic acid, which keeps in solution 
the alkaline earths as bicarbonates. The well was bored to obtain a 
supply of water which would not corrode a steam boiler, and the result 
was entirely satisfactory. 
In 1881 two more wells were bored at this i>lace, one at the hotel, 
to a depth of 145 feet, and the other for Mr. George Cochran, to a 
depth of about 130 feet. The following record is given : 
Feet. 
0-2 surface soil. 
2-12 fine clay. 
12-30 fine sand. 
30-38 yellow clay. 
38-45 sand. 
45-125 sand, with water. 
125-135 black clay, Miocene (Chesapeake). 
135-138 blue sand, Miocene. 
138-141 blue clay, Miocene. 
141-145 red gravel, Miocene.
