The outcrops round the glen are nearly horizontal^ the beds dipping 

 gently away from the excavation to the east and west ; but at the head 

 of the glen they dip at 20° and 35° to the north. Just beneath the 

 nummulitic limestone talus on the road from Karuli to the Sardi salt 

 mines^ a mass of variegated, hsematitic, earthy laterite, projects. From 

 this rock, it is supposed, the native artificers procure the material 

 which they cut into letter-weights, &e., for sale. In several parts of 

 the Sardi glen there are deposits of calcareous tufa. 



On the hilly part of the plateau above the northern end of the 



ravine, there are some peculiarly veined concre- 

 Varlegated striped beds. . 



tionary beds high up in the nummulitic limestone. 



They are of a reddish grey tint, the structure being marked by irregu- 

 larly concentric rings and thin bands of purple and yellow colour ; their 

 thickness is at most 20 feet. From these are taken those parts in 

 which the lines are most strongly developed, for knife handles, weights, 

 and such ornamental uses. The exposed parts of the beds are much 

 jointed, but, if large blocks could be obtained, they would doubtless 

 work up into a pretty marble. It is _said that the church at Shahpur 

 is flagged with stone obtained from this place, and the remains of old 

 quarries are visible.'^ 



Close to the locality at which these beds occur, there are some rem- 

 nants of the tertiary sandstones, and one consi-

derable outlier forming hilly ground; here the 



lower beds contain a number of reptilian remains and some fossil wood. 

 Bones are numerous, and parts of the heads of crocodiles have been 

 found; but none of the fossils discovered were in very perfect preserva- 

 tion. Due north of this outlier, the underlying limestone rolls up and

 by Mr. Marshall, late of the Salt Department, Sardi.
