between the nearly horizontal beds of the scarp, and the same beds tilting down under the 
plains. Before these beds disappear the dip flattens very much, or oven slightly turns up 
to the north, while near the axis of the flexure it is nearly vertical. I did not here detect 
any characteristic Jabalpur rock, but unless faulting interferes with the sequence they 
ought to be represented. The fine Dnndiwara sandstone, so much prized on the Great 
Indian Peninsula Railway, comes from the top beds of these inclined strata. Structurally 
this section corresponds with that of Zumani, only the flexure is more marked. It is 
important to remark that in both cases the sandstones reach well to the front of the run 
of the nearest metamorphic rock. The strike of the latter into the anticlinal axis rather 
suggests that they acted as a fulcrum upon which the overlying strata were bent and broken. 
No special disturbance was noticed in the trap on the Moran. In passing to the wost- 
The western inkers. south-west on the strike of the little rib of metamorphic lime¬ 
stone south of Lokartalai, at about a mile distance, there is a 
low ridge. A clear section of it is seen in the stream, showing it to be formed of trap, 
with a central band of gray and reddish clay, all having a dip of 60° to south-south-east! 
In the next stream there is a still better section of this continuous little ridge, just under 
Salei village. The clay band here is calcareous, and is locally full of JPht/sa Primepii, 
the common fossil of the iutertrappean formation. The dip is the same as before. The 
ridge passes just to south of the village, and immediately north of it there is a strong 
outcrop of hard conglomeritic sandstone, about 30 yards wide, the dip being 60° to 70° 
to south-south-east. The trap occurs again immediately north of it. Tiiis rib lasts for about 
a mile, the iutertrappean hand being traceable much further. In the Ganjal at Uskali, 
and exactly on the same strike, there is a stronger outcrop of the same sandstone. It has 
been extensively quarried in the little hill east of the village. The dip here is 45° to south 
south-east, and in front of it the trap is well seen, although the beds are massive, to have 
the same dip, gradually lowering to 5° at half a mile up stream. The iutertrappean band 
is absent in this section. Immediately below the sandstone there is a small obscure section 
of trap. Two miles further, on the same exact strike, at Kupasi and Jinwani, the rib of sand¬ 
stone appears again, still at 60° to south-south-east, and just under it at Kup&si there is a 
small crop of metamorphic limestone. This is the last appearance of the sandstone, at 
eleven miles from Lokartalai. The structural feature, however, is well marked for a much 
greater distance, and exactly on the same strike: south of Padarmati there is an outcrop 
of intertrappeans still at 50° to south-south-east; in the streams at Kathmakliera and 
binganpur, and better still in the Machak above Magardha, the zone of high dip in 
the trap is well seen. Beyond this it seems to die out, being scarcely noticeable in the 
Siani below Makrai. Magardha is twenty-five miles from Lokartalai. 
The feature just described is a very remarkable one. The sandstone of these inliers 
Interpretation of tl.em. woul(l seem to be,on g to the Bagra rocks; it is quite like the rock 
found near the metamorphics all along the boundary. It is tho 
structural feature that exhibits such a change. Even this might have been anticipated in 
kind : the steady south-westerly dip of the sandstones on tho Moran indicates a depression 
of the formations in that direction; but it was not there detected that the trap participated 
in that disturbance. This fact comes out very forcibly from these western sections; and 
they give one, too, an idea of tho magnitude of the event. For a thickness of quite 1,000 
feet the trap affects the same steep dip as the sandstones, which must, one would think, 
carry the latter to at least that depth in the ground to the south. This, of course, would 
put the chance of coal indefinitely out of reach in this immediate region; the horizontal 
extent of the feature being quite in proportion to the vertical magnitude. The geological 
reading of it is very puzzling, especially when it has to he taken from such scattered 
observations as can be made during a single march across the ground, I can only state
