Muzzooleea, may be seen a bed of chloritic schist. Dipping conform- 

 ably with the gneiss it oscillates on one side towards talcose schist, on 

 the other towards chloritic gneiss. The latter change is seen where 

 it comes into contrast with the gneiss. This intermediate rock, as 

 it may be called, is much intersected by veins of scaly chlorite in which 

 quartz is also interspersed. The veins are very tortuous, and the quartz 

 always follows the course of the chlorite. In the ascent to the 

 Kutedorna Pass, just below the village of Darna, gneiss was observed, 

 but of limited extent, and no other rock was visible. 



109. Between this Pass and Putenoo I find no notice of the rock, 

 owing I suppose to thick debris below Putenoo. In the route leading 

 down that glen, one of the feeders of the Nowgree (to Roon on the 

 latter river) chloritic and talcose schists are the only rocks observed, 

 these rocks frequently contain quartz. The dip is generally north. 

 The contact of the gneiss with the new rocks could not be discovered. 

 In the bed of the Nowgree occurs an anomalous variety of talcose 

 schist, or perhaps rather quartz rock. It is a mixture of silvery talc 

 and quartz, but is not schistose, having more the amorphous aspect 

 of granite. It contains, disseminated in grains, a mineral with the lustre 

 of quartz, semi-transparent, varying in colour from a bluish white to an 

 indigo blue. It does not appear to have any cleavage. The quantity 

 was too small to determine the specific gravity. It is infusible per se. 

 With soda it forms a clear glass. This rock has been meet within 

 very distant localities, and will be often referred to. At this place it is 

 intersected by patches or veins of chlorite. 



110. In the ascent from the Nowgree, fragments of a subschistose 

 rock, of a greenish colour, may be seen, containing probably hornblende, 

 besides chlorite ; still higher on the pass above Birsoot, straight laminar 

 chlorite schist prevails. In descending to the stream below Ketoo, the 

 same rock continues, but having a fibrous structure; it contains nodules of 

 quartz, and the chlorite is always observed to be bent round them. The 

 dip was found here to be S. E. In the bed of the stream blocks of gneiss 

 are seen, but no occurrence of it in situ. Chlorite schist continues to the 

 foot of the ascent leading to the village of Koolior, when it is exchanged 

 for a grey fibrous argillaceous schist, irregularly cleavable with a scaly 

 granular fracture. The dip here was also found to be S. E. Probably 

 this latter is in reality but a variety of chloritic schist. As long how-
