_6 POTASH IN THE GREENSANDS OF NEW _ER_EY.
Southeast of the area mapped as Vincentown three additional
borings throw light on the thickness and character of the overburden
in that district.
A well drilled for Dr. Hilt-reel at Sandy Ridge farm (locality 9),
about 1 mile N. 42 ° W. of the Quinton railroad station, shows,
according to C. C. HolIaday, driller, 36 feet of overburden and 23
feet of "light-colored marl." This marl may be Vincentown, but it
lies witidn the area mapped by the State Geological Survey asKirkwood
and may represent a marly phass of that formation, which
farther southeast is known as the Shiloh marl member of the Kirkwood
formation, and was formerly dug as a fertilizer. 6
A well near Hagerville gives the following record:

It is supposed that the upper bed of marl in this well may represent
the Shiloh marl member and the lower bed the lime sand
or ¥ineentown. Upon this assumption the Hornerstown marl at
locality 10 will lle 110 feet or more beneath the surface.
The well of Jerry Powell, on the west bank of Hope Creek near its
mouth (Locality 11), "a stone's throw from the Delaware," is said
by C. C. Holladay, driller, to be 264 feet deep. The greensand is 40
feet thick and 200 feet below the surface. Water is obtained from
a yellow sand beneath the marl. The marl is very compact.
Two wells about 2_ miles east of Alloway on the road to Daretown
show the increase in depth of the marl beds in the direction of the dip.
One well is on the farm of l_arvin Lloyd and the other on the farm
owned by Samuel C. Reeve and occupied by Henry Hilo. Both wells
are at an elevation of about 40 feet. Woolman _presents the following
combined record:
