THE SAGAR DISTRICT. 49 



occurring in the upper plains of Malwa, or to speak still more correctly 

 as to direction, it is a shoot up north-eastward from it. 



With regard to the northern line of demarcation, I cannot be so sa- 

 tisfactory and clear. If a line be drawn from Bhopalpur to Seronj, it 

 will pass through the formation, under review, but as to how far this form- 

 ation extends north of such a line, I have no precise information. The 

 Maltoim pass is of sand-stone, and I believe this rock ends some- 

 where between the crest of the pass and the village of Naret, not far 

 removed from its northern foot. The granite is at Tiri. An iron ore 

 is worked to a considerable extent at a spot intermediate between 

 Dhamuni and Marowra; Dhamum has the trap and sand-stone; and 

 the trap ceases five miles and a half south of Hirapiir, whilst the bare 

 sand-stone, freed from any overlying mass, continues until it may be 

 seen resting on matter incident to the primary rocks, at Hirapur, and 

 where, too, it ceases entirely. Nearly in this direction will be the 

 northern limit of the trap formation, as laid down in the accompanying 

 sketch, but much confidence is not to be placed in it ; the boundaries, 

 however, to the east, west, and south, may be offered as sufficiently 

 accurate. 



It is eighty-four miles from JBhopalpur to Bhilsa, and seventy-two 

 from Shilsa to Sdgar, and twenty more bring us to Shahpur ; and this 

 line, though not a straight line, is sufficient to give a general idea of 

 longitudinal extent. Hirapur, in the northern quarter, cannot be less 

 than seventy miles distant from the southern boundary, given to the 

 sketch ; and the whole of this extensive area is occupied by the newest 

 flcetz trap formation of Werner, subjacent to which is the new red 

 sand-stone, shooting up frequently from below through the overlying 

 rock.
