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



very large veins, their breadth being inconsiderable compared with 

 their length, and their course oblique to the direction as well as to the 

 planes of the strata; nothing like the marks of stratification can be 

 seen in them, but they are traversed by seams in every direction, very 

 similar in this respect to the smaller and less equivocal examples of 

 quartz veins. One of these masses is observed to descend the moun- 

 tain side into the bed of the stream and ascend the opposite side, 

 always keeping the same direction, limited in breadth, and easily trace- 

 able by the eye for many miles. 



226. In ascending the bed of the stream which descends from 

 the villages of Ketee and Mulsee, and here joins the Bendoolee 

 river, the chloritic schist is gradually exchanged for more decided 

 argillaceous types. These are sometimes straight laminar, easily split- 

 ting into slates, sometimes sublaminar and schistose, in which case the 

 cross fracture is easily obtainable. The former are more frequently of 

 an iron black, the latter of a purplish, reddish, or greenish hue. The 

 two routes here coincide ; below Ketee a green schist occurs, remark- 

 able for having two sets of divisions distinctly marked, forming 

 an angle of 45° with each other, the one being parallel to the schistose 

 structure ; above Ketee again, quartz rock of a bright Orkney yellow oc- 

 curs, fissured and seamed in all directions, so that a specimen of any 

 size cannot be obtained. The slates too in great part when tried under 

 the blowpipe, fuse into a slag obedient to the magnet. These indica- 

 tions point to an iron mine which is in the neighbourhood, but which I 

 had not an opportunity of examining. The dip in this glen is always 

 N. E., but the strata are nearly vertical, being frequently observed 

 from 70° to 80°. 



227. On the summit of the Pass Dewaluc Khali, quartz rock occurs, 

 and descending thence to Murara, it is found to contain talc ; fragments 

 are observed here, which are a mixture of compact felspar and quartz, 

 but the rock has not been observed in situ. Below Murara, micaceous 

 schist is established, the dip being S. 35° W., and inclination 24°. 

 It is full of small garnets ; traces of felspar may be found in it, and I 

 am not without an opinion, that gneiss is to be observed on the summit 

 of the ridge just passed, although in the immediate route quartz rock 

 alone may be visible. The micaceous schist continues to appear along 

 the bed of the Iiamgunga. Near Agura, a mass or bed of limestone,
