in the same direction and at the same angle. The chert of this band 

 is white, and the limestone contains some obscure black fossil fragments, 

 and granular knots or nodules. In the stream bank below the pathway 

 as though overlying, at a little distance, the cherty limestone, are varie- 

 gated purple, bright-red, green, gray, rusty, sandy and clay layers (14 in 

 the section), and just beyond these variegated beds in the more open 

 ground are hillocks of red and greenish clay with masses of contorted 

 gypsum. Close to the southward of this some gray clays weathering 

 greenish contain calcareous, lumpy, fossiliferous layers with Cones, Oysters, 

 &c. Associated with these are red and gypseous clays with layers of 

 deep liver-coloured sandstone, undulating over the ground with knolls of 

 gypsum appearing from beneath the red beds, being overlaid by num- 

 mulitic limestone forming small hills, in the sides of which red debris 

 is intermixed with the limestone detritus. The plain here between the 

 pass and the Jatta hills is flat, but in the deeply cut river and stream 

 valleys the soft, gray, greenish, and bright-purple beds of the tertiary 

 sandstone series re-appear, with one very bright-red zone of clay, 150 

 feet thick. They strike east and west, and are either vertical or at 

 high angles, generally dipping to the north, but show some greatly com- 

 pressed synclinal curves.
