From hear the <if)zai8ho teiu])le, the green Hichists heeoine more fissile, 

 and intercalated with a hla.ck niica-scliisl^ (mai-ked ^I.) '!''• tlie waii- 

 ward, in Hie \'iciiiity of tlie disfrict-lxjundar}^ of Uignshi-Sliirakawa 

 and Kikiita, the green scliists gradually disappear and give place to a 

 black, crystalline hornblende schist, which occu{)ies the baf>al portion 

 of the series. The thick complex of schists which we liave liitlierto 

 traced from Kadono to Ishizumi is \evy persistent and monot<Hious 

 in character thronijhont. 



Havino- briefly considered the lithological succession of the volu- 

 minous, schistose hornblende rocks, of which the whole gorges and the 

 solitary ascents of the Gozaisho road are composed, I shall add a, 

 few words on their nature. These rocks strike north and south 

 dipping eastwards with verv high angles, and being usually on end, 

 or vertical. Such being the case, it is iiulte impossible to form a deti- 

 nite idea as to the sequence (jf sujierposition within short distances ; 

 but viewing the wliole series at large, I cannot help thinking that 

 those lying eastwards must be stratigra[)hically younger than the 

 schists on the west. 



The rocks at the west end of the Gozaisho Narrows, consequently 

 the lowest of the present series, l)ear, as I have already had occasion 

 to note, the unmistakable physiognomy of a genuine cryst'dline schist. 

 They are laminated, perfectly fissile, evenly planed; in siiort, they present 

 none of the signs that would show them to have been formed from 

 some antecedent rock or rocks through metasomatic and paramorphic 

 changes so profound, tliat their original ch;u*acteristics would have 

 been effaced beyond rec(3gniti(3n. Ihit the liiglier we ascend tow^ai-ds 

 the horizon, tlie rocks become less fissile in siructm-e, appear more 

 compact and clastic, and eventually pass into a green slate, made up
