is perfectly flat, while that of the others is rather undulating and 

 irregular. The latter too are composed almost wholly of angular 

 local debris, covered with a thick deposit of peat, while these, as already- 

 described, consist entirely of rounded fragments which project often 

 at the surface. 



129. From Sinowlee the road ascends one of the ramifications of the 

 Chag Sheel ridge. At the commencement of the ascent, micaceous schist 

 is found of a dark blue colour, and splitting into very thin straight laminae. 

 It is much stained with oxyde of iron. Gneiss succeeds to this rock, 

 but in small quantity, and is again exchanged for a micaceous schist, 

 with something of a talcose aspect, and of a lead blue color. This 

 rock continues assuming more of the talcose character, and it is I think 

 certainly a mixture of prismatic and rhombohedral talc mica with 

 quartz. The laminae become undulated, and it abounds in garnets. 

 A vein is observed parallel to the layers, the centre of which was 

 either granular quartz or a mixture of quartz and felspar, the sides 

 were marked by prisms of hornblende thickly and confusedly dissemi- 

 nated. Many veins of glassy quartz, both white and yellow, were 

 observed, but so fragile that no good specimen could be detached. 



130. The rock continues to the village of Chupar, containing fre- 

 quently veins, if they be so called, of gneiss. The veins never ramify, 

 and they are always parallel to the laminae of the containing rock; 

 below Chupar gneiss is again found in mass, and beyond it again talco- 

 micaceous schist, enclosing a vein similar to that described Art. 129, 

 consisting of granular quartz or a mixture of quartz and felspar, with 

 crystals of hornblende disseminated. This vein has a porphyritic 

 structure, is a most singular rock, and affords by the definite nature of 

 its character, a clue to the connections of widely distant masses. It 

 will be seen hereafter of what common occurrence it is within this 

 tract, and yet it is a rock I have never seen except in these mountains. 

 The dip is pretty uniformly in this neighbourhood, N. or E. of N. 

 wherever it appears uncomformable, it is but for a short distance. 



131. Beyond the talco-micaceous schist, one with straight laminae, 

 containing garnets and oxydulous iron is met with. In descending from 

 Bulor into a lateral glen, the glandular type of gneiss before noticed 

 as occurring below Broang (Art. 80), and at other places, is met with, 

 and in the bed of the stream is seen a talco-micaceous rock with
