GABAD AND BaITOOL RoAD ON THE EAST TO THE ChOTA TaWA RiVER. 



The north-eastern portion of this tracts from Hoshungabad to 



Alluvial plain from Hurda, consists of a gently undulating plain of

About Hurda rock begins to appear more generally in the streams,

rocks to the north are largely exposed. This is especially the case in 



the neighbom-hood of the Nerbudda, which runs through a rocky bed 



between low hills of Bijawurs and gneiss. 



To the south is the western extension of the Puchmurry and other 



hills, much diminished in height ; and gradually

 which is proved by pebbles brought down by the stream, but which was 

 not reached. («) It is far within the hills, and is evidently of small extent.

trap is seen in the river, then, from beneath the trap, coarse conglomerates 

 crop out, dipping at about 10° to west-20°-north. These conglomerates 

 contain pebbles of various kinds, some of metamorphic rocks, amongst 

 which quartzite predominates, others of the peculiar purphsh quartzite- 

 sandstone of the Vindhyans ; a few are of red jasper, and mixed with the 

 mass are blocks, frequently 2 or 3 feet across, of soft felspathic sandstone, 

 evidently derived from the Damudas which are in place close by.

 country and could not spare the 3 or 4 days it might have required to hunt it out and survey it.
