the nature of the stone is likewise very variable from the finest grain of 

 very great hardness, to a coarse grain so loosely held together by the 

 felspar as to appear rotten and to be quite friable. 



7th. The greenstone and syenite are of great variety. 



I annex a translation from Jacquemont's travels, regarding the geolo- 

 gical features of this part of the country, as shewn in the hill of K&linjar. 

 I give it as the work is rare and not translated. Extract from Jacque- 

 mont's travels, Volume 1, Page 427. 



Between Nyagawn where M. Jacquemont entered the district and 

 Kalinjar — 



"There is nothing to note but some hillocks of hornblende rocks. 

 The slaty structure is entirely unknown, — all are granitic ; the suppres- 

 sion of quartz turns it into greenstone which decomposes into concen- 

 tric balls ; its predominance on the other hand gives a straight laminary 

 structure to the rock probably due to the felspar, which is intimately 

 mixed with the quartz, when the latter is very abundant. It is the 

 same as at Adjighar. 



" At length we pass the river Baugi formed by the junction of several 

 streams from the high land, and we enter the great village situated 

 between its right bank and the foot of the hill of Kalinjar. 



" Geological description of the hill of Kalinjar. 



M Up to the foot of the escarpement the mountain is formed of syenite 

 rocks which in their varieties and bearing, resemble the appearances (of 

 those) at Adjighar. The syenite, consisting of rose-coloured felspar, 

 whitish quartz, and black hornblende (in the form of large crystals), is 

 found principally in large unconnected blocks on every stage of the 

 hill ; also varieties of the same rock with smaller crystals ; others where 

 their flakes (laminae) of mica are intermixed with the hornblende, with- 

 out entirely suppressing it. Rocks of felspar and of actinolite or of 

 felspar and of diallage, doubtful with reference to the nature of their 

 component parts here as well as at Adjighar, and lastly those greenstones 

 which become decomposed into concentric balls; these are the principal 

 kinds. It is equally difficult to say which predominates over the other 

 ■ — which forms the mass of the mountain intersected by the veins of 

 others ; but all the passages of one species, or even from one simple 

 variety to another, are cut off; in the extent of the same mass, one
