In the meadows east of Mullica Hill about half a mile, excel- 

 lent marl is dug from a level many feet higher than the bed of the 

 stream. As far as the general aspect of the surface enables us to 

 judge, the position of this bed is lower than the green stratum in 

 Mullica Hill ; but whether they are different horizontal beds, or 

 one and the same stratum connected by a slight dip to the east, 

 are points demanding additional research to settle. 



The width of the visible marl tract in the neighbourhood of 

 Mullica Hill, is about three miles. 



The several beds seen at Mullica Hill are discernible in the 

 same relative positions in various places more to the southwest. 

 At Colston's, four and a half miles off, the marl is very good. 



The analyses which follow will exhibit the character of the
