between it and the gypsum. The opposite side of the glen exposes red 

 and gray disturbed tertiary sandstone and clay beds, or the unconform- 

 able surface deposits sloping to the south. 



Among these tertiary sandstones, &c, are beds having much more 

 the aspect of the lower than the upper part of the series seen to the 

 west. They are all disturbed, dipping northwards at 40°, 15° and 20°, 

 and sometimes show synclinal curvature pushed over to the south. In- 

 tercalated in a purple portion of these beds, shaly below and with 

 sandstones above it, is a thin, yellow, marly nummulitic layer, the asso- 

 ciation of the rocks much resembling the thin limestone bands of the 

 Subathu rocks along the northern side of the Pot war country. At 

 another spot a little to the eastward similar thin bands of limestone 

 were again noticed in these purple and red tertiary rocks. One side

The limestone in both cases appeared- to be truly intercalated in the 

 purple and red tertiary sandstones, but it could not be ascertained whe- 

 ther both were parts of the same band slightly displaced by slippage, 

 or whether the eastern, which lies a little to the northward of the other, 

 was a different and somewhat thicker layer. Neither exceeds 2 or 3 feet.

 marly limestone such as that abovementioned, was seen in an inverted
