between the Nummulitics and the Infra-Trias (see also horizontal 

 section No. 2). That this fault is of considerable importance and one 

 of the largest yet brought under our notice is evident from the way 

 the Nummulitics come in contact with some of the lowest beds of the 

 Infra-Trias. Nevertheless, along the same line of strike in theSirban 

 sections this fault was non-existent. It was replaced by an ordinary 

 fold of the rocks, with a regular ascending series up to the Num- 

 mulitics in the valley going north-east to Shakur Bandee, — see sketch 

 section, p. 112. If we now wind our way along the foot of the hill- 

 spurs from Nuwanshuhr to Dhnmtour, we shall find for a very con- 

 siderable way that we cross nothing but the outcropping edges of the 

 Nummulitic formation. In themselves, these beds of nodular limestone^ 

 shale, and marl, often crowded with foraminifera and shells, are some- 

 what confusing. It is difficult to correctly estimate whether the 

 section is a uniformly descending one in the direction of Dhum- 

 tour, as the general lie of the rocks would indicate, or whether there 

 are one or more folds with inversions to reckon with. The section (hori- 

 zontal section No. 2) of this part represents the results of several 

 traverses in and out of the deep straight little gorges near Nuwan- 

 shuhr and across the stony slopes and hollows north-west of Gulee. 

 It will be gathered from that section that at the little pass near 

 Gulee, where the present road to Tandidni goes, there is a conspi- 

 cuous change in the general appearance of the section, but it is not 

 certain that this implies any great structural change. Between that 

 point and the fault separating the Nummulitics from the Infra-Trias 

 sub-zone near Mundroch, there are two bands of ochre or chrome 

 coloured limestone containing belemnites in the same state of pre- 

 servation as are those of the typical Cretaceous band. At the little 

 pass itself there is another band indicated in the section, but cut off by 

 a fault from the surface. It outcrops, however, a little further on in 

 the direction of Tandiini near Kuthwal. The two former bands are 

 too small to be coloured on the map. From the general nature of the 

 section in the surrounding Nummulitic rocks, as well as from the non- 

 appearance of Spiti shales associated with the Cretaceous, it seems
