JOO GEOLOGICAL FEATURES OF SINGAPORE. 
Here are the first indications of (what I suppose to be) the 
secondary strata. The rock is a hard slate considerably fractured. 
This rock dips to the southward at an angle of about 25° 
The strata were a quartzose bluish grey compact slate, bare¬ 
ly yielding to the knife; a darker coloured sort and harder; a 
grey quartzose and still harder slate, blue; a compact schist not 
"yielding to the knife; a very hard lighter coloured and more mas¬ 
sive schist, and lastly a dark blue compact stratum, quartzose and 
ferruginous, fracturing cubically.
