86 ARTESIAN WELLS ON THE ATLANTIC COAST. [bull. 138. 
There are considerable carbonates, some sulphates, and but very little chlorides, 
associated with lime, magnesia, soda, and potash, combined, as indicated by the anal- 
ysis, in the form of lime carbonate, magnesia carbonate, soda sulphate, soda carbon- 
ate, potash sulphate, soda chloride (slight). There were also some iron oxide, a little 
siliceous and aluminous matter, and a trace of ammonia. The water was somewhat 
alkaline. Scale matter is mostly lime and magnesia carbonate, with some iron oxide 
and silica and a little aluminous matter, which exists largely as clay in suspension 
in the water. 
Riverton, Burlington County. — I have no further data for this well 
than are given in the table, page 46. 
Rumson Necli, 1 Monmouth County. — The well bored in 1890 on Rum- 
son Neck is near the corner of the Ridge road and Bellevue avenue. 
The beds penetrated are as follows : 
Feet. 
0-31 top earth. 
31-86 marl. 
86-92 shells and sand. 
92-95 hard stratum. 
95-100 gray sand. 
100-150 marl or clay. 
150-190 sand. 
190-210 clay, with thin sand seams. 
Beds from 31 to 95 feet are glauconitic. 
The water is from a sand bed in the Matawan series, probably the 
same horizon as in the deeper Seabright and Redbank wells. The 
pumping capacity of the well is 60 gallons a minute. 
Sayreville, Middlesex County. — At Sayre & Fisher's brickyards two 
wells, 2J inches in diameter and 80 feet deep, furnish an abundant supply 
of water. They are in clay to near the bottom, where sand and gravel 
were found. The water is soft and does not corrode steam boilers. It 
is slightly ferruginous. 2 The water horizon is iu basal beds of the 
Raritan formation. 
A deep boring has also been made at this locality to a depth of 976 
feet, in which the gneiss was entered at 70 feet. No water was found 
in this well except at 300 to 350 feet, where about 7 gallons a minute 
was obtained. 
Seabright, Monmouth County. — Nine wells are reported, of which 6 
are down 125 feet, and yield on pumping 35 gallons each per minute, 
the water rising 10 or 12 inches above the surface. All are 3 inches in 
diameter except one, which is 6 inches, but yields no more water than 
the others. Three others have been sunk to 258 feet, and stopped in 
fine white sand which yields fresh water of good quality. From each 
of these three wells there is a flow of about 40 gallons per minute at 
5J feet above the surface. It is thought that this yield could be
