Americas Greatest Problem: the Negro by R.W. Shufeldt. Chapter 11 part 2.

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.
