THE KAY A NS- OF THE NORTH-WEST OF BORNEO. 14} 
about sixty miles, the river’s course is north-east, bounding 
the semicircular ranore of hills from which the Bintulu, Tatau, 
and all the rivers between the Rajang and the Baram have 
their sources. From Balaga the Rajang traverses the coun¬ 
try eastward, and the Kay an s, by following its course, arrive 
at the great central mountain of Tibana, and thence by a 
journey of five or six days on land reach the. rivers Tidan, 
Coti and Banjar, according to choice. The Bu«;is people of 
the Coti, also take the same route on their trading excursions 
to the Kayans of the north-west. On this coast the Baram is 
the next river of importance inhabited by the Kay&ns, more 
so however from the amountand value of its produce, than for its 
navigable qualities, the bar at its mouth having only about 
ten feet in depth at high water. Of the other rivers, Bintulu, 
Tatau, Balinian and Muka, the former, in latitude 30° 13” 
30’ north, and longitude 113° 3” 15’ east is the deepest, having 
at high water from twelve to fourteen feet in depth on the bar. 
Of the wild animals inhabiting this part of the highlands of 
Borneo, the rhinoceros is the largest, and is found about the 
upper parts of the Rajang, where also the largest species of 
orang utan is said to exist. In many parts of the hilly coun¬ 
try the leopard and bear, of a small description, abound and 
the wild hog and deer are plentiful in all parts. The goat 
also is found in a wild state. In the Kay4n language there is 
no name for the lion, elephant, horse, cow, and many other 
well-known animals, but there is a proper name for the Tiger, 
which animal the Kay 4ns describe as being of a large size, 
and which they persist in saying does exist in several districts 
of the interior. In the interior of Rajang the two species 
of monkey which produce the Bdtu Nakit or Bezoar stone 
abound. One is a large black monkey, with a long tail, called 
nakit. The other is large and red but has no tail, and is call¬ 
ed basi. The bezoars are found in the stomachs of these two 
kinds, but not in all of them, as sometimes from ten to twen¬ 
ty are killed without obtaining it. The bezoar, if not quickly 
extracted after the animal is killed, is said to be of inferior 
size and quality. 
The configuration of the country does not vary more than 
do its human inhabitants. Besides the mongrel Malays of 
the coast, there are eleven other tribes located between them 
and the Kayans, namely the Kanawit, Bakatan, Lugat, Tan- 
yorig, Tatau, Balinian, Punan, Sakapan, Kajaman, Bintulu 
and Tilian—the majority of whom are tributary to the Kdyan. 
The six first mentioned are all more or less tatooed, both male 
and female, and certainly have all sprung from the one called
