The water comes to within 10 feet of the surface, and 500 gallons per 
ihour have been pumped from the well. 1 
The well at the skating park obtains water in a gravel bed at a depth 
<jof 130 to 136 feet. The record is as follows : 2 
Feet. 
0-30 sand. 
30 thin bine clay. 
30-118 black clay marl. 
118-130 sand. 
130-136 gravel. 
The Matawan horizon furnishes the water for these wells. Those in 
Woodbury at from 130 to 163 feet are from the basal Matawan beds, and 
those at 80 and 113 feet are from the higher Matawan horizon. The 
well 2 miles south of Woodbury at 120 feet is probably also in this 
higher Matawan horizon. The well a mile north of Woodbury prob- 
ably reaches the basal Matawan beds, for they rise quite rapidly to the 
north. 
Woodstown, Salem County. — A well was bored at this place in Decem- 
ber, 1891. The site is on low ground near the creek, where the surface 
is about 30 feet above tide level and near the outcropping Middle Marl 
bed. The record of the boring is as follows: 
Feet. 
0-4 meadow earth. 
4-16 gravel and limestone. 
16-56 greensand marl, with shells near bottom. 
56-126 gray coarse sand, no water. 
126-186 quicksand, with flakes of mica. 
186-246 black sand marl. 
246-276 black muddy quicksand. 
276-296 blue clay, hard and tough. 
296-340 white sand, with lignite, water bearing, underlain by white 
clay and red clay in succession. 
The limestone at 16 feet belongs to the Middle Marl bed. The coarse, 
gray sands and quicksands are identified as the Redbank sand bed, 
though of increased thickness. The micaceous quicksand corresponds 
to the clay, which occurs over the lower marl bed at many localities. 
The black sand marl, 60 feet thick, also appears to be abnormally thick 
if it be the Lower Marl bed, but it is probable that the lower part of 
this black sand marl and the black muddy quicksand represent the 
Matawan clay marls which underlie the marl bed. The white sand cor- 
responds to the Laminated sand. At the bottom the red clay is recog- 
nized as the top of the Raritan series. 3 
In the first well at this place no water was found in the sand bed 
from 61 to 131 feet, but subsequent borings have developed a large sup- 
ply from that depth. The wells are six in number and 6 inches in
