Geological Survey as marking the base of the Middle Lias. 

 The party proceeded to the ironstone mines, where sections 

 were seen showing the junction with the clay and ironstone. 

 In most pits the ironstone is covered with sand from which 

 numerous erratics have been found.* 



After a lengthy tour through the ironstone mines, the })arty 

 proceeded to the Scunthorpe Brick and Tile Works, where a 

 fine example of tufa was seen. It is locally called the ' Sunken 

 Church ' or ' Stone Curtain,' to which are attached the cus- 

 tomary legends ; the tufa is a fine example of a calcareous 

 deposit, and the channel through which the water flowed is still 

 well seen. After a lecturette on this interesting formation, by 

 Mr. Henry Preston, F.G.S., the party proceeded to the lime 

 works, wherxe a new section was examined. The section here 

 seen was thought to represent the Basement beds of the Lower 

 Oolites. Fine examples of typical Lias, etc., fossils were secured.
