Later in the same year (1903) the sections were examined by 

 Mr. Walker, who sent me details Avhich agreed with my own 

 observations. In response to my request that he would search the 

 greensand for fossils, he wrote : 



' We [himself and his son] broke up a good many of the blocks [on the tip- 

 heap] and also a lot of the section, but it was so damp that the fossils were 



softer than the matrix and they fell in pieces I could not see our bed 



[the limestone] pass into the greensand : I think it occurs underneath it ; at 

 the far end of the pit our bed is seen, but the fossils are very badly pre- 

 served : we got a few out, but the space between was covered by the fluid 

 clay which had run down. The fossil conglomerate -bed seems to thicken 

 towards the end of the working.' 



On my next visit, in the summer of 1904, I found that some 

 novel and highly interesting features had been revealed, as shown 

 in the middle part of fig. 4. This figure is a combination of the 

 three drawings made in my note-book in 1903, 1904, & 1906, 

 and gives a somewhat shortened section across the pit from north- 

 west to south-east.
