ARTESIAN WELLS ON THE ATLANTIC COAST. 
[BULL. 138. 
absence of water in the Monmouth Park deep well probably indicates 
that no water exists in basal Raritan beds in that immediate region. 
The rate of dip of the basal beds is difficult to establish definitely 
over a wide area, because the wells which reach them are mainly along 
the strike of the formation and near its western margin. In the sec- 
tions on PL III all available data on the subject are presented, and in 
the discussion of prospects in the various counties, on pages 108-115, 
some estimates are made for depths to the beds in the various regions. 
Beds in the Raritan formation (higher than basal beds). — The Raritan 
formation is, as before explained, somewhat heterogeneous in composi- 
tion, and no general subdivision of its components has been made. 
Alternating strata of fine sands and clays predominate, and some beds 
contain deposits of coarse sands and gravel which are water bearing. 
Whether these beds are widespread and at the same horizon or hori- 
zons is not known, but it is probable that they are not. Some wells 
in the middle and upper Raritan beds have yielded waters and others 
have not been successful. My judgment would be that the occur- 
rence of individual water-bearing beds is irregular and restricted, but 
throughout the area there is a fair chance for finding water at one 
depth or another in the Raritan formation. As the thickness of the 
formation is not great, the safest plan will always be to prepare to sink 
to the basal beds, but if water is found above, further sinking may not 
be necessary. The following wells appear to obtain water from middle 
and upper Raritan beds:
