tory extinction. The above two are typically schistose-made 

 orthogneisses. (3) The third is a whitish, thin schistose rock of 

 parallel-planed structure with spots of garnet. Microscopic exami- 

 nation sho\vs it to be composed of orthoclase and plagioclase, 

 quartz and a little green biotite, besides zircon and garnet, show- 

 ing, except in the case of the zircon, highly cataclastie structure. 

 The common garnet is crushed being traversed by parallel cracks 

 and filled with chlorite. It is a leucocrate dyke now made 

 schistose together with intruded granite. It is a granulite in its 

 present form. The whole complex strikes N. 20' E, wâth pseudo- 

 cleavage plane dipping Avestw^ards. Therefore it underlies the 

 Metamorphic Mesozoic (Algonkian?) schists of Kiin-san^\ If the 

 strike direction were prolonged, the complex would extend to the 

 forested headland of Pißn-san, already referred to "l The general 

 physiognomy is that of an abraded hill of 10 — 20 m now greatly 

 dissected and filled with a gravel terrace as at the eumnai of Ham- 

 ybl ''^. The abraded hill extends to Kang-gifông and even farther 

 nortlnvards. Sometimes the crest of the steeply inclining rock 

 runs like a sand dune with great regularity on the soutli of the 

 town last-named. 



Having crossed a stream ''\ we saw toward the north an 

 isolated, rather high granitic hill, jutting out from an eastern 

 mountain Avitli the east- west trend, and commanding the whole 

 view. Ou the flattened top is an old castle, and at its south 

 foot is the cinnnai of Ik-scm^\ the site of one of the ancient 

 capitals of the kingdom of Pälh-clnßl '^^ or " One hundred Families." 



Our road then led across a plain and fmall}^ over a hill of 

 granite (PI. XXVII. /f/. 1) to the provincial capital, Cliißn-jiju.
