48 THE TRAP FORMATION OF 



and Garalcota, on the right hand, and Shahpur, one march on the left, 

 or westward ; and then, if a line be drawn between these places as res- 

 pectively mentioned, leaving the nameless rivulet as it occurs between 

 ShaJipur and Pattariya, in the lias, and also continue this line south- 

 ward to the red sand-stone hill, which overhangs Tendukuira, in the 

 vale of the Deori, there will be a tolerably correct eastern boundary 

 given to the trap formation of Sugar. 



The vale of the Deori is of an older formation, than either the lias 

 of the Hattah district, or the sand-stone subjacent to the trap of Sugar. 



That red rock, which has been alluded to as skirting the Deori, 

 near Tendukaira, has its accompanying trap hills, and these, in their 

 general direction, bend their course to Hasanahad; indeed at Sh moiv, ov 

 soon after passing south of that place, the road from Sagar to Hasanabad, 

 descends this trap range, and afterwards continues at their feet, on 

 the south side, the whole distance to Hasanahad. Let it be added to 

 this, that the road for fifteen miles south of Hasanabad, or as far as 

 JPetraotah, is on the alluvial matter of the Nermada, a deep black basal- 

 tic mould, and that at Petraotah, a hilly country again occurs, consist- 

 ing of primary rocks, contingent on the granite of Shahpur, Nhnpdm, 

 and Bitul, and then there is a definite bounding line on the south. 



,i ' If the cantonment of Bhopalpur, on the right bank of the river 

 ■Newas, be taken as a point, and a line be drawn from that point to the 

 Nermada, so as to pass between Siiltanpur and Deivas, such line will 

 cut through the eastern part of the trap formation, described by Captain 

 Dangerfield, as that officer marks both those places in his sketch; in- 

 deed, that which is under description by me, is a mere continuation to 

 the eastward of the newest floetz trap formation, named by that officer, as 



occurring
