SPORT AND SCIENCE ON THE 



hua-ch'eng, where we hunted wild sheep, I find 

 the following notes in my diary : — 



" These mountains are entirely plutonic, vol- 

 canic, and metamorphic. The low foothills, which 

 run in a series of low parallel ridges, are com- 

 posed of lava (porphyry). Next (working west- 

 ward) comes some white and greenish stone, 

 which I take to be a metamorphosed felspar. 

 Beyond this and rising to a great height, with deep 

 cut ravines and valleys, come gneissic and schistose 

 rock, with intrusions of granite. Working still 

 west an extensive outcrop of white marble is 

 crossed. Beyond this again the rock seems to be 

 granitic, gneissic and schistose. The schists, I 

 believe, are chloritic, while the granites certainly 

 have a large proportion of felspar. A certain 

 amount of iron-stone, but no coal, was noticed." 



Probably the mountains north and north-east 

 of K'uei-hua-ch'eng are similar in formation to 

 those north-west.

From K'uei-hua-ch'eng to Pi-ch'ien-ch'i we tra- 

 versed low-lying country at the foot of moun- 

 tains and hills of the usual archaic formations. 



North-west of Pi-ch'ien-ch'i, where we entered 

 the mountains, we encountered extensive beds of
