154 ARTESIAN WELLS ON THE ATLANTIC COAST. [bull.138. 
CAROLINE COUNTY. 
The Denton well to 359 feet and the Federalsburg well to 234 feet 
indicate two Chesapeake horizons in this county. The first is in basal 
Chesapeake beds, in which waters probably underlie the entire county 
at depths of from 350 to 450 feet, for they are tapped at Cambridge to 
the southwest at 370 feet. The impure water of the deeper Federals- 
burg well is in a higher horizon, which was not reported at Denton, 
but may extend across to the 100-foot wells at Easton. The Magothy 
horizon lies about 400 feet below the basal Chesapeake water, and no 
doubt underlies Caroline County. As to the deeper horizon nothing 
can now be predicted for the southern counties of the Eastern Shore. 
DORCHESTER COUNTY. 
The basal Chesapeake waters which are so satisfactory at Cambridge 
and LeCompt's store probably underlie all of this county at depths 
which increase to 500 feet in the southern section. As the horizon is 
not a water bearer at Crisfield, it may end in southern Dorchester 
County, so that we can not be confident of its continuation far south of 
Cambridge. A well sunk to the Magothy beds in any portion of the 
county will probably find the same water as at Crisfield. The higher 
Chesapeake horizons can not be predicted widely in the county, as they 
were not reported at Cambridge or Crisfield, but they probably extend 
at least a few miles from Federalsburg, and they may be found to be 
widespread. 
WICOMICO COUNTY. 
The unsatisfactory water at 101 feet at Salisbury is not a fair test of 
the resources of this county for underground waters. It would appear, 
however, from the experiences of the Crisfield well, that only the deeper 
horizons continue into the county, and my only prediction would be 
for the Crisfield water at depths near 1,000 feet. Possibly the basal 
Chesapeake waters, or even higher Chesapeake waters, may extend 
into the county, but this can only be suggested as a possibility. It is, 
I believe, worth testing. 
SOMERSET COUNTY. 
The Crisfield wells prove the existence of large supplies of water, but 
so far they have been too saline for general usefulness. These waters 
probably underlie the entire county at depths near 1,000 feet, for the 
county lies along the strike of the water-bearing beds. Still deeper, 
in the Potomac formation, there may possibly be waters at intervals 
down to the crystalline rocks, or the bed rock, which I should expect 
to find at about 1,500 feet. 
WORCESTER COUNTY. 
The Ocean City well obtains water from upper Chesapeake beds, in 
which there may be water under all of the county, or at least its eastern
