ABORWrNAL TRIBES: DIVISIONS OF RACE. 
33 
Mon, Evidently there were colonists sent to Pahang in 
early days by some highly civiHsed people; the old 
mining shafts prove it. The Jakun aboriginal tribes 
who inhabit the country where the old mines were 
situated seem to have picked up from the colonists the 
numerals that they used, just as their fellow- tribes in the 
north and west are now learning the Malay names for 
all nnnierals over "three" The Jakun numerals, like 
the relics of the ancient kingdom of Ligor, iudicate that 
it was the western and not the eastern branch of the 
great Mon-Khmer culture that influenced the Peninsula. 
This fact is to be regretted from the standpoint of 
historical research since it is the other branch — the 
Khmer or Cambodian branch — which is the more likely 
to attract investigators,

We have seen that the boundary-line between the 
Sakai divisions is sometimes very easy to draw. In 
such casHS, as at Snngei Raya and Tanjong Malini, the 
observer passes abruptly from one language and culture 
to another; but more often, perhaps, he finds that the 
clianofe is effected throucfh a whole series of mixed 
tribes. The Semang Paya fade gradually into the Sakai 
Jeram through the Semang Bukit; the Sakai Jeram 
chanofe slowly into the Sakai Jt'her through the Orang 
Kenchior of the Upper Perak River. In these instances' 
the change is mainly linguistic ; for all these tribes differ 
very little indeed in race and culture. But when we 
come to Western Pahang we find a long series of 
communities that are quite indeterminate ; they borrow 
their words, characteristics and customs sometimes 
from Central Sakai, sometimes from Northern Sakai,
