LOWER TRANSITION ROCKS. I39 



however, such is not the case. The injected veins are not branches 

 of the granitoid mass, but veins of pegmatite which permeate both the 

 granite gneiss and the Dharwar trappoid. An injected mass of the 

 pegmatite of appreciable size lies several yards within the trappoid mass 

 in one place. The trappoid here also shows no trace of alteration in 

 contact with the old granitoid floor, and I am quite at a loss to under- 

 stand Newbold's comparison of this contact corner with MacCulloch's 

 classical section of the granite intrusions at Cape Wrath.

3 miles north-north-east of Metra, which forms a link between the 

 Copper mountain synclinal and the Kampli patch of Dharwars, which 

 is really a westward extension of the Penner-Haggari band.

of which shows a delicate green stain. The 



stone somewhat resembles a green avanturine and would make a pretty 



material for inlaid stone-work of the Agra type, or for mosaic work. 



The whole eastern side of the Daroji extension of the synclinal is 



immensely obscured by cotton soil, and the boundary itself absolutely 



hidden everywhere, but is doubtless a faulted one, the Dharwars 



being thrown down against the granitoid.

 Bellary ghat. points of interest occur along the half finished 



ghat road leading to Bellary. The ghat runs east to west mainly along 



the south side of the axis of the range, which rises several hundred feet 



above the watershed. To the south of the watershed the range is much 



lower ; the schists and trappoids which there compose it have been 



denuded to a much greater extent than the haematites to the north. 



This schisto-trappoid tract is, except along the course of a few streams 



which have cut themselves shallow ravines, briskly undulating, almost
