BORNEO

interrupted range extends at a tolerably uniform dis¬ 
tance of 80 or 90 miles from the coast, bending 
sharply at right angles towards its termination at Cape 
Datu, and forming the natural inland delimitation of the 
Sarawak and Brunei territories. In the greater part of 
its extent it is unknown, but Mounts Malu and Marud at 
the head of the Brunei river are estimated at 8000 feet, 
and Mount Baling at over 7000. Between the Batang 
Lupar and the Seriang Lake the range appears to be dis¬ 
continuous, as it also is towards the western boundary of 
Sarawak, where the hills—for the elevation becomes 
much diminished—have frequently the character of 
abrupt isolated blocks. The highest elevation in this 
part is Mount Pu, in the neighbourhood of Tanjong 
Datu, which is believed to be about 6000 feet in height. 
Still farther west, in the Menteradu (Montrado) district, 
Mounts Bawang, Pandau, and others form a separate 
group of insignificant height. 
Prom near the middle of the chain just considered, 
three principal ranges are believed to originate, and not 
far from the centre of the nucleus thus formed lies 
Mount Tebang, which is as yet unvisited by Europeans. 
Native accounts on the whole concur in describing this 
mountain as of great height, and giving origin to the four 
great rivers of Borneo, and it is further stated to have 
its summit white. It is, nevertheless, improbable that 
a snow mountain should exist without having been 
viewed by some of the many travellers who have ex¬ 
plored the rivers, and it may be concluded that the story 
in this respect is without foundation. The three main 
ranges have a general direction of E., S.S.E., and S.S.W., 
and mark out the basins of the Kay an, Mahakkam 
(Koti), Barito, and Kapuas. They are composed, for 
much of their extent, of isolated hills or mountains, so
