In Angola the Portuguese distinguish between the _Pretos_, that is, the "civilised," and the _Negros_, or unreclaimed natives. Yet both terms mean the same thing, as also does _Ba-Fiot_[274], "Black People," which is applied in an arbitrary way both to the Eshi-Kongos and their near relations, the _Kabindas_ of the Portuguese enclave north of the Lower Congo. These Kabindas, so named from the seaport of that name on the Loango coast, are an extremely intelligent, energetic, and enterprising people, daring seafarers, and active traders. But they complain of the keen rivalry of another dark people, the _Judeos Pretos_, or "Black Jews," who call themselves _Ma-Vambu_, and whose hooked nose combined with other peculiarities has earned for them their Portuguese name. The Kabindas say that these "Semitic Negroes" were specially created for the punishment of other unscrupulous dealers by their ruinous competition in trade. A great part of the vast region within the bend of the Congo is occupied by the _Ba-Luba_ people, whose numerous branches--_Ba-Sange_ and _Ba-Songe_ about the sources of the Sankuru, _Ba-Shilange_ (_Tushilange_) about the Lulua-Kassai confluence, and many others--extend all the way from the Kwango basin to Manyemaland. Most of these are Bantus of the average type, fairly intelligent, industrious and specially noted for their skill in iron and copper work. Iron ores are widely diffused and the copper comes from the famous mines of the Katanga district, of which King Mzidi and his Wa-Nyamwezi followers were dispossessed by the Congo Free State in 1892[275].
