Feet. 
66-75 blue clay. 
75-172 coarso white sand with iron water. 
172-180 white clay. 
180-201 coarse white sand lying on white clay. 
The well yields 70 gallons per minute of very satisfactory water. 
Dr. Henry Leffnian has kindly sent the information that it contains 
three parts per million of iron, a small amount of carbonate of lime, 
and very little chlorides. 
According to Mr. Woolman 1 there are three wells at the Peddie Insti- 
tute. One of these has a depth of 76 feet, the others which were bored 
in 1894 have a depth of 428 and 500 feet, respectively. The deeper 
boring reached crystalline rocks at a depth of about 482 feet, and the 
428-foot well found a water supply in coarse gravels and sands in the 
basal beds of the Earitan formation. It is stated that some coarse 
sand and gravel were found at a depth of about 200 feet — near the 
base of the Matawan formation — and between the depth of 240 and 255 
feet, and still coarser gravel and sand from 385 to 435 feet. Lignite is 
reported at 175 feet. The crystalline rock yielded much white quartz, 
some mica, and a few small garnets. Four additional 6-inch wells have 
recently been sunk to depths averaging 200 feet. 
Holmdel, Monmouth County. — The well on the Gidean & Daly stock 
farm is 601 feet £eep, and obtains about 12 gallons a minute from a 
horizon low in the Raritan formation, probably the same as the Key- 
port and Atlantic Highlands wells. 
Jamesburg, Middlesex County. — At the State Reform School a well 
has been bored to a depth of 481 feet. For the first 285 feet the diam- 
eter was 8 inches, the remainder 6 inches. The record is as follows :
