Descripción:

« the civilizations of Africa are the civilizations of the Hamites, its history is the record of
these peoples and of their interaction with the two other African stocks, the Negro and the
Bushmen […] The incoming Hamites were pastoral 'Europeans' - arriving wave after wave - better armed as well as quicker witted than the dark agricultural Negroes »
