The sands and clays below would then be of Potomac age. It is greatly 
to be regretted that the evidence is not more definite in regard to the 
formations in this well. 1 
A chemical analysis of the water from a depth of 957 feet, by H. J. 
Patterson, is as follows :

Salisbury, Wicomico County. — The water supply for this place is 
derived from a gang of 15 driven 6-inch wells to depths of from 18 to 75 
feet. They yield in all about 200 gallons a minute. 
A deeper boring was made to 101 feet for lower waters, but the result 
was not satisfactory, because the water was strongly impregnated with 
mineral matters. The following analyses are given of the water from 
this well and of the water from the shallower wells which afford the 
present supply. The analyses were made at the Maryland Agricul- 
tural College :

1 Mr. L. Woolman has recently published some additional data regarding the dia- 
toms and other organic remains from the Crisfield wells in New Jersey report for 1894, 
pp. 181-189, PI. VII. He states that from 930 to 933 feet there is a glauconitic bed 
containing a Nodosaria identical with the form occurring in strata immediately over 
the Middle Marl (Middle Cretaceous or Severn) of New Jersey.
