SEC. 5.] LODAEE AND JOORUN RANGE. 14S 



One of these gray shale beds among the ferruginous and sandstone 

 rocks on the west side of the road from Doodaee to Davesur was found 

 after several hours'" search to contain a few specimens of Pecopteris and 

 Taxodites in a very fragmentary state. 



The appearance of the rocks in this little pass is striking, though 



the broken scarps of the ground are but 50 feet 

 Colouring of the rocks. . , . , i i ■ i 



or so in height, the bright colours of the beds 



varying from pink white and yellow to orange and deep red, and pre- 

 senting numerous kinds of deposition and stratification, many of the 

 sandstones having a peculiar rugged, spongy, or warty aspect common 

 in the upper beds.* This locality is full of springs of brackish water 

 caused doubtless by the retentive character of the shales, and probably 

 contributing to the formation of the wet jheel or marshy place north of 

 Dhamurka on the edge of the Runn. 



Near the southern entrance to this pass quantities of white earthy 

 North and South of decomposed rock lie about some wells. Rocks quite 

 "^^' as white occur in the upper group of the jurassics, 



but these may possibly indicate the occurrence of a few of the sub- 

 nummulitie beds beneath the surface debris. Not far from the north 

 end of the pass beside the road to Joorun and on the margin of the 

 Runn, a very small exposure of light yellowish muddy rock contains 

 numbers of casts of small gastropods, the shells in general being entirely 

 removed ; the rock may dip at a high angle to the northward and most 

 probably belongs to the tertiary group. 



Westward of this in the low strip of ground between the base of 

 the hills and the Rainn, very similar hard yellow mudstone, apparently 

 horizontal, was observed in one or two spots. 



* This structure is ofteu observed iu the Mahadeva rocks of Central ludia.
