text: So far, archaeology has been unable to assist substantially in rounding out the picture of Africa's past. At the present time archaeological evidence is not only sporadic, but for many sections of the continent almost completely lacking. Even where, as in northern, eastern, and southern Africa, comparatively large numbers of archaeological sites have been investigated, the correlation of their cultures has only begun, and many of the theories which have been established are still ill-founded.  
  Little can be said about the early cultures of the continent which manifest themselves here as elsewhere in different types of stone artifacts. There is still a great deal of uncertainty concerning the  
  human races which might be associated with these prehistoric cultures, but there exists the probability that the later phases of Africa's Stone Ages may be connected with such races as the so-called Boskop and Strandloopers, which may be regarded as the progenitors of the small-statured Bushmen of present-day South Africa.
