To the south-east of Bagh rises a hill composed of three small 

 transverse ridges connected together, which 

 Hill south-east of g\ ve || the appearance of three separate sum- 

 mits. A section through the hill is given be- 

 hind the main section in horizontal section No. 1. From it we see 

 that the base of the hill is an outlier of Trias limestone above the 

 slates, whilst the upper parts of the mountain are composed of grey 

 and Nummulitic limestone. Between the two lies the Jura-Creta- 

 ceous band, which has evidently acted as a line of weakness, above 

 and below which, the corrugations of the strata are not harmonious. 

 The reversed fold-fault inserted on the map and indicated in the 

 section near the middle of the hill is peculiar, because it follows the 

 axis of an isoclinal arch in the Grey limestone and the trough of a 

 synclinal in the Trias* below. 



The whole of the southern part of the Bagh hill is a simple outlier 

 of Triassic and Supra-Triassic rocks, complicated by the corrugations 

 and faulting to which I have referred ; but to the north, in the direction 

 of Maira and Bandee, the Nummulitic limestone alone is visible, 

 plunging down to a very low level and continuing as a narrow faulted 

 strip into the bed of the Dore river and across it to Tirati. Its appear- 

 ance near Tirati is given in horizontal section No. 2 (PI. 4), where its 

 extraordinary position, wedged in between masses of slate and Trias 

 limestone at so low a level, is difficult to understand. 



The geology of the south-eastern portion of the Bagh-Maira hill 

 was worked out by Mr. Edwards and Sub-Assistant Hira Lai. The 

 stream separating it from the Bara Gali spur is cut out along the slates,
