Matawan, Monmouth County. — A boring at this place passed through 
about 100 feet of bluish clay with marl grains, and then into line sand 
with an abundance of water. Unfortunately, this water carried too 
much fine sand in suspension and was not available. The boring was 
continued in the sand to 204 feet without finding gravel or sand 
coarse enough to keep the lower end of the pipe clean, and the work 
was suspended. 1 
The water at 100 feet is in the mid-Matawan horizon, which is satis- 
factory in wells at Redbank, Monmouth Park, Monmouth Beach, Sea- 
bright, etc. With proper treatment, this well could no doubt have been 
made a success at 100 feet, or it could have been deepened to the mid- 
Raritan or basal Raritan horizons with good prospects for finding other 
water-bearing beds. 
Mays Landing, Atlantic County. — Two wells here furnished a moderate 
supply of water through a 2J-inch tube. They are at an elevation of 
about 8 feet above high water. The record was as follows: 
Feet. 
0-20 coarse gravel. 
20-60 quicksand. 
60-90 beach sand, with clay layers, perhaps 1 foot thick. 
90-96 fine black or blue tough clay underlain by some water. 
96-136 glass sand and no clay. 
136-150 Sand, with no increase in water. 
The supply from the first well was 12 gallons per minute at first, but 
it finally decreased to 7 gallons. The second well was sunk to 130 feet, 
and yields 3 to 4 gallons per minute. The temperature of the water is 
57°. The solid matter in the water at 110° was 7.60 grains. It con- 
tains only a trace of iron and is slightly alkaline. 2 
A 6-inch well was sunk in 1891 to a depth of 176 feet which yielded 
25 gallons per minute. The temperature of the water was 56°. 
The section, according to Mr. Woolman, is as follows: 
Feet. 
0-22 gray sand, granular. 
22-51 gray sand, finer. 
54-72 bluish-gray, clayey sand, considerable wood. 
72-98 bluish clay, diatomaceous. 
98-112 clayey sand, diatomaceous. 
112-116 sand, bluish when wet. 
116-125 alternations of sand and diatomaceous clay. 
125-132 sand, water. 
132-142 sandy clay, diatomaceous. 
142-149 bluish clay, diatomaceous. 
149-151 sand, water. 
151-165 alternations of sand and diatomaceous clay. 
165-172 bine clay, richly diatomaceous. 
172-176 sand, water bearing. 
The clays below 100 feet contain Miocene diatoms. The water hori- 
zon of the 130-foot and 176-foot wells at this place is identical with that
