"The fifteene kingdomes of the land of Negros knowen to us, are all situate upon the river of Niger, and upon other rivers which fall thereinto. And all the land of Negros standeth betweene two vast deserts, for on the one side lieth the maine desert betweene Numidia and it, which extendeth it selfe unto this very land: and the south side thereof adjoineth upon another desert, which stretcheth from thence to the maine Ocean: in which desert are infinite nations unknowen to us, both by reason of the huge distance of place, and also in regarde of the diversitie of languages and religions. They have no traffique at all with our people, but we have heard oftentimes of their traffique with the inhabitants of the Ocean sea shore."
