Disorder. 



It would be difficult to give within any reasonable space an adequate 

 idea of the disorder in which these groups occur; 

 the saline series seems to form the core of the ridge, 

 and this is capped by the post-tertiary conglomerates. Its eastern side 

 shows the salt beds and other parts of the saline group, or else tertiary 

 sandstones and clays of a purplish and gray colour, but on the opposite 

 side a long vertical rib of the nummulitic limestone is conspicuous near 

 the base of the hill, and a great mass of the post-tertiary conglomerates 

 seems to have slipped down from its place. The main mass of the latter
