76 THE TRAP FORMATION OF 



the principal points, where the sand-stone protrusions are entitled to the 

 rank of hills, and where they are more elongated individually, and more 

 clustered together ; for instance, Dhamiim, and Maltoun, Gherpdra, and 

 Sdtgerh, — Sapyle, Hdtgerh, — Grdspur and Shilsa. — The eastern edge of 

 the sketch, as stated in the commencement of this notice, is where the thin 

 covering of the lower lias lies on the upper portion of the new red rock 

 series, viz. clays, marls and calcareo arenaceous sand-stones, tender and 

 often variegated, and it is desirable to note in particular that such is the 

 case. At the descent to Tendukaira, or at the S. E. corner of the trap, 

 it is a sand-stone rock ; but the connection of this rock, with the subjacent 

 matter along the south boundary, is concealed by the basaltic alluvium of 

 the Nermadd interposing. The western limits join the trap of Malwa, and 

 therefore it need only be added, that I bring the sand-stone as far west as 

 Narsinhgerh. Along the north side probably there is sand-stone the whole 

 length, it certainly does reach up to Maltoun, and forms the bounding 

 rock thence to Hirapur ; and iron ore occurs at many points in that line 

 similar to what it is at that particular spot. 



To conclude: — The rock about Sehore and Bhopal is, upon good au- 

 thority, considered as similar to that of Sdgar ; although there was infor- 

 mation given, that rock salt was there produced, and of course the mind 

 conceives Gypsum, &c. as equally existing, or in a word, that the superior 

 portion of the red marl formation was to be found west of the somewhat 

 diagonal line pointed out ; but the accuracy of this last report is at pre- 

 sent to be doubted, more particularly, as Gypsum is only known in the Sd- 

 gar bazar as a production of Rdjputdna, and the salt chiefly used is that 

 of the Samhher lake, annually brought along these latitudes, and sold by 

 the Binjaris as far east as Serguja. However be this fact, it is, with 

 the exception now noticed, that I wish to offer the sand-stone of the dis- 

 tricts described, from a general personal acquaintance with the whole, as 



remarkable
