The Nordics are... rulers, organizers, and aristocrats... The Alpine race is always and everywhere a race of peasants... The Alpine is the perfect slave, the ideal serf... the unstable temperament and the lack of coordination and reasoning power so often found among the Irish... our army sample of immigrants from Russia is at least one half Jewish... Our figures, then, would rather tend to disprove the popular belief that the Jew is intelligent...
We must face a possibility of racial admixture here that is infinitely worse than that faced by any European country today, for we are incorporating the negro into our racial stock ... The decline of American intelligence will be more rapid than the decline of the intelligence of European national groups, owing to the presence here of the negro.
