THE LIMESTONE SPRINGS OF ST. JOHN'S, BERKELEY,

 Fresh Water in Cooper River.

 Mr. Jokn Mazyck's. At the foot of a bill, a deep excavation is seen, into which 

 the Spring issues ; the water is quite clear and the movement of the sand where 

 the stream escax^es can be distinctly seen, the depth at this spot beuig over thii'ty 

 feet. This excavation is the commencement of a large Creek, supphed entnely 

 by this Spring and a second one, about 200 yards south of it. The second spring 

 IS much the larger, it is near forty feet deep, and the ripple of the water is seen 

 disLinctly at the surface. From the quantity of water plants, although the 

 water is quite clear, the bottom cannot be seen. This large Creek empties im-

 portion of the Canal between "Coal Hill Lock" and Cooper River in a navi-
