Fault at Stamford j and Eastward. 



Crossing the Wetland, from the old Lincolnshire town of Stamford 

 to the Northamptonshire parish of St. Martin, the important fault laid 

 down in Mr. Judd's map and its consequences are encountered. Of 

 the precise line taken by this fault, I was unaware until I saw that 

 map, although well acquainted with its peculiar and anomalous re- 

 sults ; which extend some miles to the east, and some of which were 



* From a band, with plants and wood, similar to that overlying Slate-bed at 

 Collyweston.

 at the conclusion of this Paper.
