WATER RESOURCES. 415

Assays of waters from this county are given in Table 1, pp. 496, 497,
assays Nos. 96,97. These are discussed on page 488.

Artesian Prospects—The thinness and disconnected character of the
Coastal Plain sediments over much of the county render them unim-
portant as sources of artesian supplies. Along the southern border of
the county, however, where the Patuxent formation is thickest its beds
may be expected to furnish fair supplies at depths not much exceeding

100 feet, and it is barely possible that at low levels close to the streams
flows may be obtained.

although a few of the driven wells reach 60 feet. The water comes
from the lower sandy portions of the Pleistocene formations or in the
deeper wells from the upper sandy beds of the Miocene. Along the
scarps where the lower sandy beds of the Pleistocene formations rest
- upon the more compact Miocene beds, as at Winton, numerous small
springs occur. These are, however, but little used.

At Winton two deep wells have been drilled, one of which, situated
on low land near the Chowan River, has a flow of about 1 gallon per
minute from a depth of 135 feet. In this well a small overflow was
also obtained at about 100 feet. The other well, drilled to a depth of
165 feet in the main part of the town on the Chowan terrace, encoun-
tered the same water-bearing strata. Not obtaining a flow, the well
was not used for a considerable length of time, and when attempts
were made to pump it, the pipe was found to be full of sand.

The only other drilled well in the county is at Tunis, the situation
of this well being similar to that of the flowing well at Winton. A
flow was struck at 165 feet, but the casing was driven only 130 feet.
The well flowed about four months, the flow gradually decreasing until,
on account of a cave-in between the end of the casing and the water-
bearing stratum, the flow ceased. In the fall of 1906 the well was
cleaned out and now has a flow of about 34 gallon per minute.
