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



141. Chloritic schist is seen again at Kandara in the Greenduala glen, 

 which furnishes a middling sized stream to the Kalee ; beyond the chlo- 

 ritic schist-gneiss is again found near the village of Baroo, Amorphous 

 patches of earthy granite may be observed, so soft and crumbling as to 

 yield easily to the spade. On the summit of the Pass a talco-chloritic 

 schist obtains, and continues to the mines at Pokree, fragments, however, 

 of hornblende schist being scattered about in some numbers ; beyond 

 this point no gneiss was observed in proceeding south; we may therefore 

 return to Mumdal below the Toaugnath Pass, where the account of this 

 formation left off. (Art. 103.) 



142. This village is situated in the high bed of the Dulalee river, 

 which has its rise in the schist of the Toongnath mountains, and 

 joins the Dhoalee just below Gopisur. The route leads down the 

 glen to turn into the valley of the Dhoalee ; very little rock in situ 

 was observed, indeed only one patch, which was of too little extent to 

 say precisely whether it was granite or gneiss, the toughness being such 

 as to set at defiance the hammer, and consequently prevent its effecting 

 a fracture of the rock, so as to judge of its mineralogical composition. 

 It was a roundish amorphous mass with a few irregular seams project- 

 ing but little above the surrounding surface, and thus, from its want of 

 sharp corners, increasing the difficulty, occasioned by its toughness, of 

 detaching a specimen. Fragments of hornblende rock, of quartz rock, and 

 of gneiss, are abundantly scattered over all this tract. One block, pro- 

 bably part of a vein, was observed, consisting almost entirely of that 

 variety of hornblende called actynolite ; part of the containing rock still 

 adhered, being a fine granular mixture of felspar, quartz, and mica, 

 the first ingredient in greatest quantity. The actynolite has rather 

 a confused structure ; apparently large concretions formed of radiating 

 bundles of prisms. The specimens obtained were not remarkable for 

 beauty. 



143. A more remarkable phenomenon was the occurrence of a huge 

 mass, composed apparently of very similar ingredients to the secondary 

 sandstones. It was a solitary rock which stood in the bed of the 

 Dulolee, the top being covered with grass and shrubs; strictly it 

 might be called a conglomerate, containing many large boulders or 

 rounded stones. The base was rather fine grained, consisting almost 

 entirely of quartz sand, and apparently held together by the slightest
