14 GUNONG TAHAN AND GUNONG RIAM. 
Tanun was made.in a dug-out with a crew of Malays recruited in 
the neighbourhood of Kuala Tanun. This crew was the worst I 
have ever had. We arrived at our destination without serious 
iishap, however, and I landed at the little-known Kampong 
Cherual, not far from the Kelantan border. It consisted at that 
time, as far as I could discover, of only one house, therefore it was 
an easy matter to find the oldest inhabitant. He was an old, but 
still active Malay named Yusuf bin Sleiman, who had, he said, 
lived there for over twenty-five years. It was clear then that he 
was just the sort of man I wanted to tell me the names of the 
mountains and the course of the rivers in the neighbourhood, so I 
persuaded him to show me a way up the north end of the Cherual 
limestone hills to a spot where we had a magnificent view of the 
Tahan Range, and where I obtained the hill-sketch shown in Plate 1. 
The names shown in this hill-sketch were all written down at 
the time of making the sketch at the dictation of Yusuf bin Sleiman, 
and | was careful to get him to look along the compass sights in 
order to avoid mistakes. The s\nonyms were given me by him 
also, but it is interesting to note that although the name Gunong 
Tahan was recognized, he and the other inhabitants called the 
mountain Gunong Rotan. They also knew it as Gunong Ulu Tanun 
on account of the 8. Tanun, so I was informed, rising on its flanks. 
This raises an interesting question about the Kelantan-Pahang 
boundary, which is determined by the watershed of the Kelantan 
and Pahang Rivers. The exact boundary will not be fixed until 
the country is surveyed in detail and it will probably be difficult to 
define on the west side of the Tahan Range, since the country 
between the Tanun and the Kelantan drainage is almost flat. The 
watershed runs about east and west, however, and is said by the 
Cherual Malays to follow on up to the summit of Gunong Ulu 
Kamua. On the west side of the range the drainage south of Gu- 
nong Ulu Kamua goes, they say, into the Tanun on the north and 
the Kechau on the south. The course of the Tanun near Cherual 
certainly supports this statement, and also the statement that it 
rises on Gunong Tahan. On the east, however, there is reason to 
suppose that the Kelantan-Pahang boundary runs southward along 
the Tahan Range as far as Gunong Tahan, and then turns east- 
ward as the watershed of that great tributary of the Pahang River, 
the S. Tembeliug. 
The country between the Cherual limestone hills and the 
Tahan Range is gently undulating, and it appeared to me that a 
great mistake has been made in attacking the mountain from the 
Tembeling side. Waterstradt is the only traveller I know of, who 
has tried the ascent from the west, if I understand his account of 
his: journey correctly. By this route one could be at the foot of 
the range: in four days easily from Lipis, whereas the journey from 
Lipis to Kuala Teku takes at least six days. Moreover the Tanun 
has few rapids, whereas the Tahan is barely navigable for the 
smallest boats.
