114 ARTESIAN WELLS ON THE ATLANTIC COAST. [bull. 138. 
GLOUCESTER COUNTY. 
The many wells sunk along the line of the West Jersey Railroad 
have thrown much light on the distribution of underground waters 
in this county, and they produce a large supply of fine water. The 
relations of all these wells and their water horizons are shown on the 
western end of section 4, PI. Ill, so that there is no need for an 
extended discussion of them. The Mullica Hill well, which is some dis- 
tance off the line of the section, has been projected on to it. This well 
clearly draws its water supply from the Redbank horizon. The failure 
to obtain water from the Redbank horizon in the well at Glassboro 
probably indicates that the water does not extend that far to the east- 
ward, but it is possible that the water was passed. The basal Mata- 
wan water has been found in every well which has been sunk to the 
requisite depth to reach the beds, and no doubt they would have been 
found at Glassboro in the next 150 feet. The water in beds about 60 
feet above the base of the Matawan formation made a good showing at 
Sewell at 380 feet, and in some of the shallower Woodbury wells. It 
was not reported at Wenonah. The basal Raritan and mid-Raritan 
water horizons have not been explored east of Gloucester, but there is 
every reason to believe that they may yield water to at least as far east 
as Sewell, possibly much farther. The Pitman Grove, Clayton, and 
shallower Glassboro wells appear to obtain their waters from the base 
of the sux)erficial capping of post-Chesapeake formations. The water 
horizons found in the wells along the main line of the West Jersey 
Railroad undoubtedly extend to the west and southwest in Glouces- 
ter County, with practically the same relations as shown on section 4, 
PI. Ill, and on the map, PI. II. 
SALEM COUNTY. 
The waters above described in Gloucester County appear to underlie 
Salem County with about the same relations. They have not been 
extensively explored, but the wells at Woodstown and Quinton give 
much confirmatory evidence. The Redbank horizon has proved to be 
very satisfactory at Quinton, where it was found at a depth of 170 feet, 
and at Woodstown it yields an enormous supply at a depth of 140 
feet. A well at Woodstown also found water in the basal beds of the 
Matawan formation at a depth of 340 feet, and in beds low down in the 
Raritan formation at a depth of 77(3 feet. 
WESTERN CUMBERLAND COUNTY. 
There are less reliable data for this locality than for any other in the 
region, and no predictions can be offered with any degree of confidence 
until further well boring has been done. The failure of the deep well 
to 090 feet at Green wich to obtain water would appear to indicate that 
the Redbank horizon, which yields so much water to the west and north, 
does not extend so far as we might expect, but it should be borne in
