level; it is found most advanced on the Kymore ledge, there is an exten- 

 sive spread of it to the east and north of Buxwaho; it reaches well up 

 into the wide valleys of the Rewah ridge, stretches uninterruptedly across 

 to the ridge of the outer scarp near Herdeepoor and continues along it to 

 the south-west by Jerra and Amkwao ; however, inside this line as at 

 Soonwaho, the sandstone weathers out again in the valley ; to trace its 

 outline closely would require a map on a large scale. On the rid^e of 

 the Rewah sandstone, I did not find trap east of the gorge of the Beos. 

 On the Rewah table-land it comes in at Puturia ; it is not here at the 

 general level but forms the upper part of a hill of which the lower third 

 is formed of the shales and limestones of the Bundair group — all being 

 quite horizontal.* 



The northern limit of the trap is more interesting ; at Tingunnah and 



Neuakher it is seen, immediately under the scarp

of the Kymores, resting on Semri rocks, where 



they are nearly on a level with the granitic plain: at Mudunpoor 



it is got at about the same level in a valley of the Kymore sandstone ; 



these are the only two places in which I found this trap below the outer 



scarp. From the sandstone table-land it has been much denuded north 



of Maltown, but outliers are found much more north ; Mr. Everest 



notices it at Esa<mrh, N. W. of Chandairee. I do not know on what 



authority Mr. Greenough takes it nearly up to Agra. 



Of the trap rock itself there appear to be here two prominent varieties, 



differing perhaps more in texture than in aggregate

composition: one is apparently a true basalt, a 

 dark green, compact rock, weathering angularly and not prone to decom- 

 position ; the other has more the aspect of a modern lava ; it is a 



* There must have been a strange restoration in the stratification since Mr, Everest's 

 visit ; he remarks on the same place, " at Puturia, the trap first comes in but for thirty or 

 forty miles to East the strata of sandstone had become broken and disturbed, dipping in 

 various directions."— Jl. As. £oc. Bengal Vol. v, p. 478.
