lower Manchhar beds. The place is to the east of a ridge called Hup- 

 kani. The beds dip east at a low angle, and pale buff limestone, full of 

 minute organisms, of open texture and somewhat arenaceous, thinly- 

 bedded and flaggy, is seen resting upon a paler bed rather more arenace- 

 ous, but otherwise similar ; then, after a break, comes in descending order 

 another similar band, 2 feet thick, closer and harder than the others, 

 and below this again impure sandstones, occasionally pebbly, with minute 

 Foraminifera and fragments of Ostrea, Anomia, Balamis, &c. All the 

 above beds are marine, but beneath them are soft, thick-bedded, grey, 

 buff and dun-coloured sandstones. Of these, 60 feet were exposed in one 

 section, 100 in another. With the sandstones an argillaceous nodular 

 conglomerate is sometimes associated, and both sandstone and conglo- 

 merate are characteristically Manchhar. 



At Lehra, 4 miles south- west-by- south from Murad Khan's " band," 



a small fault, striking west-north-west, crosses the 



boundary between the Gaj and Nari groups. Other 



parallel faults occur to the south-west, but some of them are too small to 



be shown in the accompanying map. 



The hot-springs at Mugger Peer (Magar Pir, or, more correctly, Man- 

 Hot-springs at Mugger gah Pir) rise in the Gaj beds just above the base. 

 Peer - The spring near the bungalow, inside the garden, 



has a temperature of 118°, but that to the westward, outside the garden, 

 is no less than 127° Fahr., and is probably the hottest spring in Sind. 

 The boundary between the Gaj and Nari beds curves greatly near 

 Gaj beds near Mugger Mugger Peer, owing to a small anticlinal, followed 

 Peer - to the westward by a synclinal roll of the beds. 



After a deep S-shaped curve, the base of the Gaj beds runs south-west to 

 Tape Monze. The coral bed can be traced at the base of the Gaj rocks 

 for some distance round the curve south-west of Mugger Peer, but then 

 dies out, and is not met with again to the south-west. Before dying out it 

 forms a low semi-circular ridge, not shown on the inch map, being doubt- 

 less too small to be marked. In the much higher semi-circular ridge, 

 which is represented on the map, and which is composed of rocks some
