the region south of Rancoeas Creek, east of the line of the Burlington 
and Camden turnpike. Its relations, dip, etc., are shown in the west- 
ern end of section 2, PI. III. 
In the Maple Shade well at 64-97 feet, in the Fellowship well at 131 
feet, in the Marlton well at 200 feet, and in the Hartford well at 161- 
167 feet was found the water of the horizon in the lower half of the 
Matawan beds, but it does not appear to have been utilized. It was 
not reported in the other wells which were bored into the basal Mata- 
wan or the Raritan beds. The water in the base of the Lower Marl 
bed was found in the wells at Medford at 183 feet, at the well 1J miles 
south of Marlton at 155 feet, and probably at the well 4 or 5 miles 
southeast of Marlton at 316 feet. As the supply is large I am confi- 
dent that the horizon extends far to the eastward of the Lower Marl 
outcrop, as shown on the map, PI. II, and in section 2, PI. III. 
The extent of the Redbank water horizon in the county is not yet 
fully determined, and it may be found to be widespread. The wells in 
the Medford region at depths of 70-150 feet found in it a supply of 
200 gallons per minute, and a large supply was found in the wells at 
Marlton at a depth of S6 feet, at the well If miles northeast of Medford 
at 125 feet, at 70 feet in the well 2 miles east of Marlton, and others. 
These are the only wells that I have heard of which touch the horizon, 
and I shall await with great interest to hear that wells have been sunk 
to the southeast and east where the water horizon may be expected to 
extend, at least under the area shown on the map, PI. II, and with the 
relations shown in section 2, PI. III. The general occurrence of this 
water in wells in the counties to the southwest gives much encourage- 
ment that it may be expected to extend at least some distance to the 
northeast. 
WESTERN CAMDEN COUNTY. 
Only the lower water horizons have been tested in this region so far 
as I know, and they have proved entirely satisfactory in all cases. The 
waters at the base of the lower marl bed and the Redbank horizons 
have Qot been reached, but there is every reason for believing that 
they extend across the county, as shown in map, PI. II, and in section 
3, PI. III. 
The basal Raritan waters are at depths from 62 to 129 feet in wells 
in Camden, the depth increasing quite rapidly to the east, to 174 feet at 
Pavonia and 270 feet at Gloucester. A higher Raritan horizon has been 
found to be very satisfactory at a depth of 149-162 feet at Gloucester, 
at 67-82 feet at Pavonia, and at 196 feet at Collingwood. The Glouces- 
ter wells at 65-102 feet obtain a large supply of water in the basal 
Matawan beds, according to Mr. Woolman, and this same horizon is 
tapped at 130 feet at Mount Ephraim, and also, probably, at 80 feet, 
three-fourths of a mile from Mount Ephraim. The relations of these 
waters and their extent are indicated on the map, PI. I, and in section 
3, PI. III.
