Mutual encroachments and interpenetrations have probably been continuous, and indeed are still going on. Yet so marked is the difference between the two groups, and such is the tenacity with which each clings to its proper domain, that, despite any very distinct geographical frontiers, the ethnological parting line may still be detected. Obliterated at one or two points, and at others set back always in favour of the higher division, it may be followed from the Atlantic coast along the course of the Senegal river east by north to the great bend of the Niger at Timbuktu; then east by south to Lake Chad, beyond which it runs nearly due east to Khartum, at the confluence of the White and Blue Niles. From this point the now isolated Negro groups (Base and Barea), on the northern slope of the Abyssinian plateau, show that the original boundary was at first continued still east to the Red Sea at or about Massowa. But for many ages the line appears to have been deflected from Khartum along the White Nile south to the Sobat confluence, then continuously south-eastwards round by the Sobat Valley to the Albert Nyanza, up the Somerset Nile to the Victoria Nyanza, and thence with a considerable southern bend round Masailand eastwards to the Indian Ocean at the equator.
