Natural History. 61 



Recently, at one of the meetings of the Lincolnshire 

 Naturalists' Union at Sleaford, I had an opportunity of 

 examining this district, and, in a pit called " Greylees," a few 

 miles east of the Ancaster Gap, I made the following note : 

 " in this pit the rubble at the top of the Oolite is much broken 

 up and contorted, dipping in every direction, and curved and 

 folded in an extraordinary manner, and on the south side of it 

 the underlying rocks show signs of folding. This may be 

 connected with the uplift in the Gap through the Oolite cliff 

 at Ancaster, which lies a few miles off to the west, where the 

 Witham once flowed ; and the disturbance of the rubble may 

 be due to the same cause." 



The present straight course of the Witham into Brayford, 

 as it approaches Lincoln, is due to modern requirements. 

 Formerly it branched off westward into Boultham parish, 

 where it was joined by the Till, coming from the opposite 

 "longitudinal" valley, half a mile, or more, west of the present 

 High Bridge at Lincoln, before passing through the Gap.

IT is frequently made a ground of complaint against

 the elucidation of their county fauna and flora. Now, 

 however true that may be of Lincolnshire as a whole, still 

 there are certain districts of the county the flora of which has 

 been diligently worked, and against these districts the reproach 

 cannot fairly be brought. In Louth, for instance, for many 

 years past there have been at least a few zealous adherents of
