Three Berta Dialects in Western Ethiopia

During my travels in Western Ethiopia in 1928 I collected some linguistic and ethnographical information on the peoples locally known (in Sudan Arabic) collected some linguisticas Beni Shangul. They now inhabit the region south of the Blue Nile and east of the former Sudan province of Dar Fung. Their eastern limit in Ethiopian territory is usually indicated as the River Dabus (or Yabus); but some scattered groups of Negro tribes, probably akin to the Beni Shangul, live east of the Dabus as far as the confluence of the River Didessa with the Blue Nile.
