MORCOT. 



At Morcot, in Rutland, two quarries are now being worked : 

 tbese are at different elevations upon tbe escarpment (facing 

 north-west) of the small river Chater. It is probable that the 

 lower beds of the upper quarry are identical with the upper beds 

 of the lower quarry. It will be necessary, therefore, in order to 

 understand the whole section, to combine the two ; and this view 

 is confirmed by the fact that, while beds having blue cores are 

 absent in the upper quarry, such beds occur towards the bottom of 

 the section in the lower one. 



The total thickness of the beds at the higher level is about 18 

 feet, and that of the beds at the lower level about 17 feet : but 

 these figures do not indicate the whole thickness of the Lincolnshire 

 Limestone at Morcot ; for the presence of beds of the same forma- 

 tion is to be detected still higher on the escarpment than the 

 summit of the higher quarry, and below the lowest beds of the 

 lower quarry occur slate beds (not now exposed) from which 

 characteristic fossils have been obtained : so that it is probable that 

 the Lincolnshire Limestone at this place has a thickness of quite 

 60 feet. 



The Morcot sections display the local variability of the Lincoln- 

 shire Limestone ; for, while at "Wakerley, only two miles distant, 

 the beds from top to bottom are essentially oolitic, at Morcot, the 

 sections are marked by the almost entire absence of the oolitic 

 character, there being only one bed, of a foot in thickness, which is 

 oolitic at all, notwithstanding that the numerous beds differ greatly 

 in other respects, consisting of harder and softer bands of marly 

 limestone in various alternations.
