Sec. 11.] DETAILED DESCRIPTIONS. 1 {>3 



About Wajpoor the traps have no distinct dip. Dykes abound, 

 several of them running east-20° — 30°- north as usual. At Wajpoor a large 

 dyke runs along the river for about half a mile in a direction of east-30°- 

 north. It consists of subcrystalline basalt, very heavy, and containing 

 small white grains, either of quartz or agate. 



For a long distance below Wajpoor traps abound in the rivei", but 

 their dip is indistinct. About Pargut the hills appear to be formed of 

 nearly horizontal beds. 



From Pargut to Mandvee little of interest is seen in the Taptee. 

 Much trap occurs, but with no distinct dip. There is not much of the 

 calcareous conglomerate, though a considerable quantity is seen just 

 above Mandvee. 



In this conglomerate Melania tubercitlata, MiilL, Bidimtcs pullus, 

 Gray, and a small species of Corhicula are met with. 



From Mandvee westwards, towards Ooska, porphyritic trap occurs, 

 apparently wdth a slight westwardly dip. Dykes are numerous. Just 

 below Ooska a bed of ash is seen resting on porphyritic basalt and 

 dipping about 3° to the west. Upon it comes amygdaloid. 



About Kumlapoor there is a large quantity of rock seen in 

 the river, chiefly beds of amygdaloid, the separate lava flows being 

 apparently very thin. All dip distinctly to the west at a considerable 

 angle, 13". Some of the amygdaloids are slightly porphyritic. The 

 steady strong western dip continues to below Bhodan, where the num- 

 mulitics appear. 



The pebbles in the bed of the Taptee, even at Mandvee and below, 



are not all of trap ; a few occur of metamorphic

rocks and quartzite. These must come irom near 



Baitool. This shews how certainly the presence of the diflierent rocks, 



provided they are of considerable hardness, contained in any river valley, 



may be ascertained by examining the pebbles in the bed of the stream
