supply was obtained. The stratum is a line white saud in whieh there 
are embedded logs of wood. Three pipes were sunk at intervals of 
300 or 400 feet, and the water rose in each to within 10 feet of the 
surface. The water is pure and delicious. The well is thought to 
prove the existence of water-bearing layers in the Matawan marls. 1 
The horizon is about 100 feet above the base of the formation, and is 
the same that yields water in the Monmouth Beach, Monmouth Park, 
deeper Seabright, and several other wells. 
Richwood, Gloucester County. — This well is G5 feet deep, and was sunk 
for the public school. The water is in red gravel, and the well furnished 
2,500 gallons per hour. According to Mr. Woolman the Miocene (Ches- 
apeake) marl was found at 78 feet in a test boring at this place. 2 
Riverside, Burlington County. — The water company at this place has 
8 wells, from 40 to 45 feet deep, which yield about 40 gallons each a 
minute. The materials penetrated were sands, containing a bed of clay 
extending from 10 to 23 feet. In a test boring made to a depth of 90 
feet the bed rock was found at 50 feet. The following analysis of the 
water has been furnished:

At the Philadelphia Watch Case Company's works a well was sunk 
to a depth of 200 feet, of which 80 feet were into the "mica rock." A 
flow of water, amounting to 50 gallons a minute, was found at 40 feet, 
but it contained considerable line sand in suspension. Only 18 to 20 
gallons of water per minute were found in the mica rock. The follow- 
ing analysis of the water from this well was kindly furnished by the 
superintendent of the works :
