William Archer, the English author and journalist expresses a European point of view in _Through Afro-America_ (1910).
Carl Kelsey's _The Negro Farmer_ (1903) is a careful study of agricultural conditions in eastern Virginia.

A collection of valuable though unequal papers is contained in the _Annals of the American Academy of Political and Social Science under The Negro's Progress in Fifty Years_, No.
