They also hold the office of village priest, which is there known as Bhumia, and in some tracts are scarcely distinguished from the Baigas.

Again, in Sambalpur the Bhuiyas are known as Bhumia Kol, and are commonly regarded as a branch of the Kol tribe.

Thus it would seem that two separate settlements of the Kolarian races may have occurred; the earlier one would be represented by the Bhars, Bhuiyas, Baigas and kindred tribes who have entirely lost their own languages and identity, and have names given to them by the Hindus; and a later one of the Kols or Mundas and their related tribes, whose languages and tribal religion and organisation, though in a decaying state, can be fully recognised and recorded.

And the Dravidian immigration would be subsequent to both of them.

To judge from the cases in which the fissure or subdivision of single tribes into two or more distinct ones can still be observed, it seems quite a plausible hypothesis that the original immigrants may have consisted only of a single tribe on each occasion, and that the formation of new ones may have occurred after settlement.
