Long Branch by the storms, for "both contain the same forms. The 
575-foot water horizon is thought to be the same as the one at Seven 
Islands at 510-535 feet and at Atlantic City at 700-720 feet. The 
water at 425 feet is apparently the 525-foot Atlantic City horizon, but 
it is in somewhat coarser sand. The beds at 410 feet are richly diato- 
maceous and contain Coscinodiscus excavatus, a form which occurs at 
Atlantic City at a depth of 500-525 feet, just above the water horizon. 1 
Berkeley Arms, Ocean County. — The wells are on the beach opposite 
the mouth of the Toms Eiver. The water was found at 475 feet. It 
rises to the surface, but does not flow, and is said to have yielded 60 
gallons per minute. 2 
The water horizon is far down in the Chesapeake formation, as will 
be seen in section 5, PI. Ill, and may be the same as the water horizon 
at 950 feet in the Atlantic City well, and at 335 feet at Winslow, as 
suggested by Woolman. 3

The water is pure and wholesome. It is remarkable for the quantity 
of carbonate of soda which it contains. 
Bordentown, Burlington County. — The well at the Aquatic Club

ply of somewhat ferruginous water from a depth of 119 feet. The 
following record was kindly furnished by Mr. Wiese, of Bordentown :
