A fair supply of ferruginous water was obtained at 338-356 feet, 
which rose to within 45 feet of the surface. The well was deepened to 
715 feet without finding a further supply, and was then abandoned. 
In another well a slightly ferruginous water was obtained at 156 feet 
in the basal Matawan beds, which flows about 10 gallons a minute. 1 
The deep well was unfortunately abandoned in beds not far above the 
base of the Earitan formation, so that it did not determine whether 
the basal beds of this formation are water bearing in this region. 
Delair. — The well at this place has a depth of 78 feet and draws an 
excellent water supply from a gravel bed in the Earitan formation.

quarter of a mile north of the village, entered a layer of coarse white 
gravel at a depth of 131 feet, from which a good volume of water rose 
to within 50 feet of the surface. Under the gravel a bed of marl with 
fine quicksand was driven through down to 192 feet, and then 8 feet 
of gravel, to 200 feet. The boring was continued to a depth of 260
