Pavonia, Camden County. — At the shops of the Pennsylvania Bail- 
road Company there are three wells which have yielded a supply of 
water for years. The wells are 67, 60, and 82 feet deep. They are a 
short distance from the wells of the Stockton Water Company, but on 
somewhat higher ground. Several years ago an attempt was made to 
obtain water from a greater depth and the record of this deeper well is 
as follows : 
Feet. 
0-6 gravel. 
6-16 white clay. 
16-35 sand. 
35-58 gravel, water-bearing. 
58-80 line sand. 
80-85 red clay. 
85-95 fine sand. 
95-115 yellow clay. 
115-126 yellow sand. 
126-132 coarse sand. 
132-164 gravel. 
161-174 large pebbles. 
A large amount of water was found, but the higher horizon appears 
to have been preferred. The supply is 275 gallons per minute. The 
water is very pure. It is thought that the water from the 67 to 82-foot 
wells represents the 64 to 78 foot horizon which supplies one of the 
Stockton wells. The abandoned well had probably reached the 121-foot 
horizon of the Stockton wells, and is probably the same as is drawn 
from by the wells in the southern part of Philadelphia and by a well 
at the Cooper Hospital at Camden at a depth of 129 feet. 1 
Perth Amboy, Middlesex County. — A well bored for the Easton and 
Amboy Railroad was sunk through Cretaceous clays to a depth of 130 
feet, but no water was obtained. Water was found in abundance at a 
depth of about 24 feet. 
A 12-inch boring was made at this place which found no Avater. The 
following record is given: 2 
Feet. 
0-55 black clay. 
55-61 red and white clay, a little kaolin, and 1 inch of white sand. 
61-70 red shale and sandstone. 
70-85 soft granite or gneissic rock. 
85-470 hard granite or gneissic rock. 
Pitman Grove, Gloucester County. — There are at this place eight wells, 
ranging from 60 to 80 feet in depth, all above the marl, and each one 
yielding from 1,000 to 2,000 gallons per hour. 
The marl was found at 96 feet and was prospected to a depth of 130 
feet to conglomerate, when the work was stopped and the water was
