ground, the gypsum, as usual, being apparently 



thin at its northern exposures and more largely developed towards the 



southern side of the ellipsoid. Proceeding still to the southward over this 



undulating gypseous and sandstone series the red clays are again met 



with at the foot of a long east and west escarpment rising above all 



the neighbouring hills, formed mainly of the hard

of the interior of the range, the gypsum being here much more developed 



and deeply cut through, sometimes leaving natural bridges over the 



mountain stream close to the path. Gray clays are also here associated 



with it, but though the stratification is in places plainly seen the general 



relations are obscure, and the ground is much covered with gypseous 



debris.
