AN UNEXPLORED CORNER OF PAHANG, 5 
is chiefly labour and sorrow, at least as far as coolies are con- 
cerned. Sungei Chok is not possible fora boat, but a day’s 
jungle tramp (say about 20 miles) towards its Ulu, brings one 
to another limestone pile, of much greater dimensions. Its name 
is Gua Senoorat, it is from 1,500 to 2,000 feet bigh, and has a 
cave at its base capable of holding a couple of thousand people. 
Doubtless in the fulness of time, when Kuala Lipis be- 
comes the seat of Government and Europeans become more 
plentiful in the Ulu, these huge natural monuments will be 
more closely examined, but it will always be a source of 
satisfaction to feel that I was the first European to gaze 
upon them. What millions of years must have elapsed and what 
mighty changes must. geologically speaking have occurred, 
since those huge beds were laid down in the ocean, and 
then slowly eroded and dissolved by the carbonic acid of 
the fresh water, after the ocean retreated, leaving only 
these isolated pinnacles to speak of what was once a con- 
tinuous bed of limestone. The decomposition of this Jime- 
stone doubtless has much to say for the better quality of the 
land on the Seran, of which I made mention earlier. 
Leaving Kuala Chok, two hours poling brings one to 
_Jeram Rimau, and though it is possible to drag an empty 
boat through it asI did, still future travellers would be well 
advised to make a camp, and leave their boat below it, and do - 
any further travelling towards the Ulu on foot, for a short dis- 
tance above the Jeram the river divides again into two streams 
which are both very shallow. 
The right hand branch is still Sungei Besi, and the left 
hand one Sungei Wur, the waters of which I find almost 
join the head waters of the Telom, heading from opposite siJles 
of the same spur. One day’s tramp up either of these streams, 
brings one to the base of the main dividing range, on the other 
side of which is Kelantan. 
After having my boat dragged through, and my baggage 
carried round the Jeram, 1 found it impossible to take the boat 
farther, and so made a camp at the junction of the two streams. 
On the left bank of Jeram Rimau is a mountain fully 
1,000 feet high, which the natives call Bukit Guroh, and to
