The locality to which I would draw attention this evening is the 

 extreme north-west corner of the county of Lincoln — the dis- 

 trict, in short, as the rough map (fig. 1) will show, bounded by 

 three rivers, the well-known Humber and Trent and, eastwards, 

 the little Ancholme — this last a strange name to modern ears, but 

 one which has been honoured by the mention of that old English 

 classic, Isaac Walton. It is a corner of the land unknown to fame ; 

 but we are now becoming celebrated commercially by the recent 

 discovery of a most extensive and valuable deposit of iron-ore,

respecting which I shall have something to say by and by. But, 

 besides this commercial importance thrust upon us, the district has 

 a special value in the eyes of the geologist as being a middle link in 

 the chain of the Jurassic strata, between their development in the 

 south and their somewhat dissimilar appearance on the Yorkshire 

 coast. The labours of Mr. Judd and Mr. Sharpe, in the southern 

 portion of the county, have brought into clear light the commence- 

 ment of this variation. But the state of things in this northern 

 corner has not as yet been brought before your notice.
