60 ARTESIAN WELLS ON THE ATLANTIC COAST. [bull. 138. 
feet and through a bed of " kaolin" which was troublesome in pumping 
and at last closed the pipes. The marl bed passed through at 20 feet 
below the surface is the Lower Marl. 1 
The water at 131 feet is from a mid-Matawan horizon, and the gravel 
at 200 feet is probably near the base of the Matawan formation. 
FifielWs, Great Egg Harbor Bay. — This well is on Ladd's Hummocks 
in Great Egg Harbor Bay, opposite Longport. It was bored in 1891 to 
a depth of 397 feet and then abandoned. The following record is 
given : 
Feet. 
0-40 beach sand. 
40-50 mud, with some shells. 
50-58 coarse gravel . 
58-60 white clay. 
60-66 coarse gravel and sand. 
66-70 dark clay. 
70-84 coarse gravel. 
84 water. 
84-160 gray sand. 
160-164 gray sand, with wood. 
164-275 gray sand. 
275-294 greenish clay. 
294-346 coarse sand and fine gravel. 
346-397 greenish blue clay ; solid. 
From 294 feet down, the beds are considered Chesapeake, of which 
the lower 25 to 50 feet are probably part of the great diatomaceous clay 
bed. The mud at the depth of 40 feet and the 4 feet of dark clay at 
66 to 70 feet were also noted at Atlantic City. The coarse water-bearing 
gravels from 70 to 84 feet are almost certainly the equivalent of the 
diatomaceous clay and water-bearing gravel found in the Absecon 
wells. 2 
The coarse sand and fine gravel at 294-346 feet appears to represent 
the 328-foot water horizons at Atlantic City and Ocean City, but it was 
not reported to contain water in the Fifield well. 
Freehold, Monmouth County.— Two wells were bored in Freehold in 
1889 for the village water supply. The borings were not studied sat- 
isfactorily. The first stratum of water-bearing sand was struck at 
135 feet. At 172 feet a black clay was found, which was penetrated 
to 208 feet, but whether it extended to a greater depth is not stated. 
At 255 feet white sand with fragments of wood was found, and the 
boring was continued to a depth of 322 feet. The water rose to within 
62 feet of the surface. The following record is given : 
Feet. 
40 green sand marl. 
58 black "marl" or clay, with sand. 
96-102 light-gray clay.
