ley* noted the occurrence of oolite in the Mitchell limestone in many 

 places ; it has therefore been thought safe to consider this oolite, in the 

 area studied, of Mitchell age. especially as the stratigraphic relations seem 

 to confirm this view. 



At 1', the Mitchell oolite is at the level of the track and is overlain 

 b.v 8.5 feet of sandstone. West of this the Mitchell limestone forms the 



surface rock so that siukhoiies are a conspicuous feature, but sandstone 

 fragments are found. The relations of the strata at 2 have been greatly 

 disturbed by the solution of the underlying Mitchell limestone so that a 

 sjrnclinal fold has been developed. Section I was taken at this point in 

 the eastern part of the cut. The lower limestone, No. 2 of the section, has 

 been dissolved to such an extent that only isolated blocks remain in the
