SPORT AND SCIENCE ON THE 
hua-ch’éng, 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’éng are similar in formation to 
those north-west.
