were completely angular, as if forming part of a crag or 

 scarp. 



(2) There was a general tendency among the blocks to shew a 



foliation-strike in one direction, namely along the crest 

 of the spur. 



(3) At a few places the ordinary schistose rocks in situ around 



had become more metamorphosed, and in addition con- 

 tained veins of gneissose-granite 3 — 4 inches across. 



(4) Although the obviously river-rounded pebbles or boulders 



before mentioned were scattered all over the hill-spur, 

 and even over a considerable portion of the neighbour- 

 ing spurs to the south-east, yet the large broken crags of 

 the granite were only found along one definite line, 

 namely, the crest of the ridge running north-north-east. 

 After a short thickness of somewhat arenaceous schists, with a thin 

 bed 2 — 3 feet thick of limestone or dolomite, we notice an increas- 

 ing metamorphism in the schists, until at a point on the banks of 

 the river due south of Mohrut village there is another occurrence of 

 gneissose-granite, under the same conditions as before. Low cliffs 

 on both sides of the river give an exposure as shewn, fig 44. It is 

 undoubtedly a vein intruded among the schists ; although owing to

 the section is somewhat hidden. We found beneath the fallen 

 blocks 3 or 4 distinct veins of the granite, varying from a few inches
