As no beds whatever are seen north of Sursho hill, it is impossible to

^^y* and it is quite uncertain whether the nummulitics 



lap round the base of the hill and occur in the plain to the north, or 

 whether they are faulted against the trap of the hiU; all that can be 

 seen is, that the tertiary beds which to the south have a low westwardly 

 dip, suddenly turn up and dip to the north-west at an angle of 60° to 

 80°, and immediately disappear beneath the alluvium. 



If the boundary be a fault at Sursho hill, and in favour of this view 



is the fact of the nummulitics being turned on end just south of the 



hill, the fault soon dies out to the southward j for close to the village of 



„ . ^ Maldipoor, the bed seen next to the trap (the ab-

which forms the base of the tertiary series for some distance to the 

 south, viz., a coarse conglomerate of trap pebbles. This is seen resting 

 upon the trap, wherever sections are exposed, as far south as the village 

 of Amuljhur, The bed is almost entirely composed of large rounded 

 masses of trap, some of them nearly a foot in diameter. The rock so 

 exactly resembles a trap flow disintegrating into concretionary masses 

 that only close examination can detect the difierence.

1. Very coarse conglomerate of trap pebbles and deep red clay. 



2. Ferruginous mottled clay, approaching soft laterite in appearance. 



3. Fine sand witb a band of small trap pebbles. 



4. Conglomerate of trap and agate pebbles ; the matrix of trappean detritus. 



5. Coarse sandstone, nodular and concretionary, with argillaceous layers, and one 



thin band containing trap pebbles. 



6. Sandstone, ^ Both abounding in casts of Gasteropoda ; no other Mollusca occur, 



7. Limestone, 3 nor any Nummulites : of the limestone about 4 or 5 feet are seen. 



8. Slightly ferruginous sandstone, soft and coarse, with runs of kunkur intersecting 



it vertically. 



9. Coarse conglomerate of trappean pebbles. This rests upon the trap.
