America's Greatest Problem: The Negro by Robert Shufeldt

A new edition of the 1917 classic which predicted that if America’s racial problems were not solved by physical geographical separation of the races, the US would dissolve into a cauldron of racial conflict which would be detrimental to blacks and whites alike.

Written in a strident style typical of the time—but frowned upon nowadays—this book was a second, updated, and expanded version of its first iteration, which appeared under the title The Negro: A Menace to American Civilization, in 1907.
