always tempted to sit down and look for fossils among these Vindhyan 

 shales: the conditions of their deposition seem to have been such 

 as are generally supposed to be most favorable to the abundance of 

 living things; shallow and quiet water, very gradual deposition and 

 a sufficient variety of the muddy element to satisfy a wide rano-e of taste. 

 Yet often as I yielded to the temptation I always got up disappointed. 

 Again at Nursingurh — " on north side of river are seen great spreads 



of limestone of various texture, some clear and

siliceous, others earthy, both alternating with cal- 

 careous shales ; along side are vertical banks of these crumbling shales, 

 blue and red, sandy, very thinly bedded; these, with a yellow variety, are 

 covered by a strong bed of earthy limestone, over which on top come 

 more red and grey shales ; all these have a slight inclination southwards." 

 The continuation downwards of this section may be found at va- 

 rious points, till we come to the coarse sandstone of the Rewah ridge. 



The most northerly locality I know of is on the 



river Tons, " about 600 yards above the falls ; on 

 the right bank, there is a rising ground undercut by the river, on the left 

 bank and in the bed of river the coarse sandstone of the falls shows well, 

 but immediately at the water line on the right bank about 15 feet of thin 

 shales overlie the sandstone ; the perfect horizontally of the bedding is 

 remarkable and the thinnest layers are continuous all through for 300 

 yards ; the lower eight feet are alternating gray, greenish and yellow, 

 sandy shales, wrinkled and minutely laminated, all slightly micaceous ; 

 some show ripple-marks, and in some the irregular cross markings of clay 

 might be taken for vegetable impressions and casts ; in the upper seven 

 feet there are partings of flagstones." For some miles up river occasional 

 sections of same rocks are met with. Actual junctions of the shales and the 

 sandstone are rare, this is the only one I saw ; as one might expect, the 

 rock excavation has here been greatest and the diluvial clay is thick all 

 along on this side of the valley.
