GEOLOGICAL t’EATtRES OF SINGAPORE, 97 
the vicinity of the Town and along the road to New Harbour, inclu¬ 
ding the Government hill, than in any other locality on the Island, 
while the ochry earths and clays predominate in the interior. The 
white or porcelain clays arc found [and l believe of good qua¬ 
lity for the arts} in beds, in various spots and sometimes close to 
the iron clays. 
There is a sort of soap stone looking substance, streaked red, 
white, and greenish, which is found in thin layers or massive amongst 
the clays. It is rather greasy to the touch, and has occasionally 
a fibrous texture. 
Being desirous of comparing the strata already described with 
those of several small islands lying off Singapore, I got into a 
sampan on the 1st Oct. 1841, and rowed round several of them, 
not, however, without having been pretty well drenched with salt 
water, for these boats ship water when the sea is scarcely ruffled. 
I had, however, to repeat my visits, one day being insufficient for 
my purpose. 
PULO TIMMUKCL. 
This little island is entirely composed of sandstone and clay. If 
is about GO yards in diameter and is surrounded by coral beds, and 
it is about 50 feet high. 
There are five distinct strata visible, (fig. 3.) inclined at an angle 
of about 30° to 40°, and the dip is to the SE. 
No. 1. Whitish and reddish. 
„ 2. red, 2 feet. 
,, 3. yellow, 2 feet. 
„ 4. „ 8 feet, 
„ 5. red, 3 feet.. 
„ 6. Light red and brown soil. 
A vein was here noticed of hematitic ironstone, and a very large 
block of ferruginous conglomerate lies unconnected at the base of the 
natural section of the Island. Is is intersected by veins of quartz. 
PULO CHIKUKOII. 
The sandstone strata here dip as at Pulo Timmukiil but they 
have been elevated to an angle of about 55°
