GEOLOGICAL FEATURES OF SINGAPORE. 
PULO PANJANG. 
There is on this island a hard, grey, and very quartzose stratifi¬ 
ed rock. The quartz white and lamellar, general colour, bluish, 
white, contains specs of black mica. 
BATU BERLAYAR. 
This sandstone rock stands conspicuously off a point of Singa¬ 
pore island which flanks the inner harbour or passage. 
The strata of this point are highly inclined, and in some in¬ 
stances almost vertical. They are all waved. The direction of 
their vertical line appeared to be NW. and SE.
