cxii Report of the Mineralogical Survey [No. 126*. 



Goamuttee valley. This rock dips S. 33° E., at an angle of 38°. Here 

 also may be seen a brown amorphous rock, of a very anomalous character, 

 the true relations of which further enquiry is wanting to develope. A little 

 further, micaceous schist, covered with an aluminous efflorescence, dips 

 S. S. E. This latter rock continues to the foot of the ascent, occasional- 

 ly taking in a little felspar. In the ascent to the Pass above Bhynsoo- 

 lee, gneiss is again found in strata nearly vertical, containing beds of 

 hornblende schist, and having here again come upon the tract connected 

 with the series of granite beds, we shall once more leave off, and pursue 

 two other short lines of route, which yet remain to be described pre- 

 viously to entering on those details. 



245. The first of these leads from the bridge over the Kalee at 

 Joolghat to Lohooghat, the cantonment of the 2d Nusseree Battalion 

 of Ghoorkhas. At the bridge, strata of a very pure limestone occupy 

 the bed of the river, and form unexceptionable natural piers for this 

 structure. The dip was N. E. In ascending, detached masses of com- 

 pact limestone and conglomerate, (enclosing pieces of quartz rock and 

 clay slate,) are seen ; a good deal of stalagmitic and stalactitic incrustati- 

 ons are noticed, shewing that masses of limestone are doubtless pre- 

 valent, though from the nature of the surface not always visible. At 

 Booralee, or a few miles before coming to that village, a purple argillace- 

 ous schist makes its appearance ; some of the types are granular, and 

 might be called a greywacke schist. It also passes into a compact slate 

 of a light yellow or greenish colour, very similar to hone slate ; as such 

 it has been used, and found to answer. These rocks occupy the road 

 as far as Petorahgurh, and the dip is generally N. or a little W. 



246. At Petorahgurh, patches of limestone are found in it of a 

 pure type and blue colour. This rock, as has been often observed in 

 limestones, has a sublaminar structure, weathering so as to have often 

 the appearance, in detached pieces, of a series of layers or thick leaves 

 joined together. It sometimes divides into thin slabs, which are, however, 

 very unlike the slates of an argillaceous character, as they admit of a 

 cross fracture with great facility, which is as usual conchoidal, and 

 not hackly like that of the latter rock. The schist here is very variable 

 in aspect, yet never loses its argillaceous character. At the cantonment, 

 it is quite soft, and might pass for a yellowish clay were it not disposed 

 in slates, which however will not bear handling, as they fall to pieces
