105-107 green " marl."

114 seam of gray "marl " with small shells. 
120 black deposit.

The capacity of the well in November, 1889, with a hand pump, was 
found to be equivalent to a supply of 25 gallons per minute, or 30,000 
gallons per day. The water rose to within 26 feet of the surface, when 
the pumping was discontinued. An analysis of the water made by 
Prof. F. A. Wilber showed that it contained 8. GOT grains of total solids 
per gallon, comprising:

The water is clear, tasteless, without odor, and neutral with reagents. 
The present water supply of the village is from wells about 1 J miles 
north of the court-house, at a point 100 feet above sea level and 78 feet 
below the conrt-house steps. The first well was bored to 210 feet, into 
what is generally known as the second stratum of water-bearing sand, 
but no good supply of water was obtained. The second well was bored 
to 50 feet. The marl extended from the surface to 40 feet, and was 
underlain by from 8 to 10 feet of coarse sand containing much water. 
Eight more wells were bored to this horizon, and their total yield is 
about 250 gallons per minute. 1 
The upper waters found in these wells are in the horizon at the base 
of the Lower Marl bed, and the "second stratum" is in the Matawan 
horizon, whicli yields water at Seabright, Monmouth Beach, Monmouth 
Park, Matawan, the deeper Red Bank well, and others.
