THE TRAP FORMATION OF 



angle, formed by the junction of the rivers, is occupied by it ; but, after 

 having gained the west bank of the Bheis, it is soon lost, The road 

 now continues on the trap, the hills for six miles being solely of sand- 

 ;stone ; more west than this it is merely a trap plain on which oc- 

 curs Kamkera, twelve miles from Bhilsa. Beyond Kamkera, the route 

 being now to the northward of west, the plain still continues for five 

 miles, and then you ascend and cross a range of globular trap hills, dis- 

 tant from Barsia ten miles, with nothing remarkable in the interval. 

 Barsia is on a large mound of amygdaloidal iron clay, sterile and bare 

 in some parts, apparently highly productive in others ; in the immediate 

 vicinity of the town it is gravelly and red in aspect. Four miles in ad- 

 vance, or at Rdnagerhi, this clay again presents itself, rises even to the 

 jank of an ore, and is as such worked, and the produce sold sufficient for 

 the purposes of the bazar of Barsia. Immediately around Danaora 

 the sand-stone hills shoot up. Kalukera, sixteen miles from Barsia, 

 is on the trap ; the Sumera, a small stream, winds about the village, wash- 

 ing out its way through large blocks of wacken and basalt. The fort is 

 built of egg-shaped masses of the latter, truncated at one end, which end 

 is set outwards, something like the flint with chalk to be seen in some of 

 the ancient houses of Hampshire, such as Chawton-house and Farleigh 

 Wallop, though the stones here used are four times as large as a com- 

 mon flint. Between Kalukera and Narsinhgerh (a march of fourteen 

 miles) you pass the Parwa and Pdrbaii, only worthy of notice as shew- 

 ing in their beds the trap and basalt covered with a whitish coating, and 

 cracked in to various prismatic shapes. The sand-stone range at Narsinh- 

 gerh runs directly N. and S. beyond the reach of sight. The village is 

 situated in the deepest part of a circular hollow formed by the partial 

 winding of the hills, and the trap has there found its way, though a base- 

 ment of sand-stone completely occupies the narrow throat or entrance 

 over which the road leads into the hollow. The trap is composed of balls
