223. On the Telkhunnee Pass, a brown schist is found, and thence 

 descending to the village of Bissona, various modifications of the same 

 passing occasionally into argillaceous quartz rock. Near the village, a 

 granular rock is seen composed of quartz and indurated clay, having 

 much the aspect of a greywacke. Here a mass of reddish limestone 

 is found imbedded in the slate, in extent about 50 yards by 10, and 

 capable of furnishing a very beautiful marble. Schistose rocks continue 

 to Kirsal, where traces of limestone occur in local conglomerates, in 

 tufaceous masses, and even as an ingredient in the more compound 

 schists. The prevailing type approached to that of stone slate, being of a 

 composition almost impalpable, moderately hard, and of colours vary- 

 ing from greenish grey through yellowish grey, to reddish and purpleish 

 grey. These specimens are seldom of a perfect slaty structure, the cross 

 fracture is easily obtained, and it is often conchoidal. Below Kirsal, 

 these schists assume more of a chloritic or talcose character, and be- 

 come more decidedly compound at the foot of the descent. Argil- 

 laceous schist is established of a very regular type, though it is found 

 intermixed with the green schists also, which are of a chloritic character. 



224. There is another route tending from the Boomot suspension 

 bridge to this point in which the rocks have been examined, and it 

 will be more in place to record the particulars here. This route 

 ascends by the village of Acend, in which the talcose schist observed 

 in the vicinity of the bridge is exchanged for quartz rock, containing, it 

 would appear, nests of indurated talc. At the village, a decided chloritic 

 schist is found. The dip in all the schistose rocks is conformable, but 

 in the quartzose or granular types, the strata are obscure. Between 

 Acend and Jak the same rocks continue with an occasional appearance 

 of brown tender micaceous schist. From Jak to Bendoolee, the transi- 

 tion into the latter is more frequently observable, and it also assumes an 

 argillaceous character. The granitic rock which I have for distinction 

 sake termed greenstone also occurs, forming as usual a transition into 

 the green schist. 



225. From the village, the route descends to the bed of the Ben- 

 doolee Nullah, the rock being still chloritic schist, verging on argillace- 

 ous, and enclosing huge masses of quartz rock, the relations of which to 

 the schist appear very interesting, and deserving of further develope- 

 ment. From what I could observe, it struck me, that these masses were
