The hill and frontier tribes of Assam include the Nagas, Singphos, Daphlas, Miris, Khamtis, Mishmis, Abors, &c., nearly all of whom, excepting the Nagas, are found near the frontiers of Lakhimpur district.
The principal of these, in point of numbers, are the Nagas, who inhabit the hills and forests along the eastern and south-eastern frontier of Assam.
The different tribes of Nagas are independent of and unconnected with one another, and are often at war with each other.
This inner line has been laid down in Darrang towards the Bhutias, Akas and Daphlas; in Lakhimper towards the Daphlas, Miris, Abors, Mishmis, Khamtis, Singphos and Nagas; and in Sibsagar towards the Nagas.
Hence also the universal reverence paid to serpents (raga) since those early days; though whether it simply arose from the superstitious dread inspired by the insidious reptile so fatal to man in India, or whether the verbal coincidence with the name of the once-powerful nonAryan tribe of Nagas had something to do with it must remain doubtful.
