Eastward of Joorun. 



To the eastward of Joorun the hills are somewhat broken, forming 

 a double chain converging to the east, the south- 

 ern ridge being the most lofty. Some of the 

 rocks at the base of the northern side of the chain along the margin 

 of the Runn so much resemble the upper Jurassic rocks that they have 

 been coloured as such upon the map. 



The following section from the hills northwards will show the 

 structure of this part of the country : —
