mind that this water horizon may have been carelessly passed in boring, 
an occurrence, I may repeat, which is by no means rare. 
The unsuccessful attempts to obtain water at Bayside and at Bridge- 
ton add confirmatory evidence that no waters may be expected in the 
higher horizons in the western part of the county. To the eastward 
the prospect is more encouraging, for the Yineland, Millville, Port 
Korris, Bivalve, West Creek, and Straight Creek wells all obtain good 
supplies of excellent water at depths from about 80 to 200 feet. The 
horizons of these waters are not definitely known, but they appear in 
the mam to be those in the Chesapeake beds which occur at intervals of 
from 334 to 700 feet at Atlantic City. Some of the relations of these 
[ beds are shown in section 4, PI. III.

PHILADELPHIA REGION. 
The eastern portion of this city is underlain by Coastal Plain forma- 
tions, consisting of the lower beds of the Raritan-Potomac deposits. 
These beds are water bearers and have been tapped by a number of 
wells in the city. Besides these wells quite a number of others have 
been sunk in the crystalline rocks which rise from beneath the Earitan 
Potomac beds in the center of the city and to the westward. Mr. 
Thomas B. Harper, of Jenkintown, has bored many of these wells, and 
he has given some data regarding their depth and yield.
