NotE:—Taking an outcrop of the junction beds of Lincolnshire 
Limestone and Upper Estuarine Series 2} miles N.W. of this Boring, it 
gives the dip of strata as 74 feet per mile in a S.E. direction. The 
thickness and character of the beds are about normal; and the yield of 
wateris excellent, being probably influenced beneficially by the Auticlinal 
Fold a little distance to the S.E. The Boring was made by Mr. Noble 
of Thurlby.
