Feet. 
0-360 no sample. 
360-400 sandy clay. 
400-450 clay, containing Textularia and other foraminifera.

612-650 greensand.

If the boring of this well was properly managed and no waters were 
passed by oversight, it probably demonstrates the absence of the Red 
bank and Lower Marl water horizons in western Cumberland County. 
Harrisonville, Gloucester County. — This well is a small boring on the 
farm of Mr. Joseph Cheeseman, a mile east of the village, at an eleva- 
tion of 120 feet. Mr. Woolman gives the following record: 
Feet. 
0-18 superficial gravel, with streaks of yellow clay at bottom. 
18-55 bluish clay. 
55-80 "bluish green, muddy, marly clay." 
80-90? white quartzose sand, with greensand grains. 
90-118 alternations of lime sand and lime rock, composed largely of 
bryozoans and foraminifera. 
118-122 quartzose sand, with water. 
The beds from 37 to 80 feet are regarded as Chesapeake. The water- 
bearing sand is in the middle of the Eancocas formation, between the 
lime sands and the Middle Marl bed. 2 
Harrisia, 3 Burlington County. — A well was sunk at this place in 1866 
to a depth of 306 feet, with a bore of 6 inches. Gravel and blue and 
gray clay were passed through to 180 feet, where mud, sand, and what 
appeared to be decayed wood were encountered. Farther down a gravel 
bed was penetrated and water flowed to a level 8 feet above the surface. 
The well was unfortunately deepened to 375 feet, where, without increase 
in volume, the water became strongly ferruginous and the well was 
abandoned. 
The record of this well is as follows : 
Feet. 
0-77 surface sand. 
77-85 sand. 
85-98 blue mud. 
98-108 clay, with pyrite. 
108-124 marly mud.
