George T. Flom, A History of Norwegian Immigration to the United States
“ In conversation with and in numerous letters from pioneers and their descendants, especially in Iowa and Wisconsin, I have found that the hope of larger returns for one’s labor is everywhere given as the main motive, sometimes as the only one. Whether it be the pioneers of La Salle County, Illinois, in the thirties, those of Rock or Dane counties, Wisconsin, in the forties, or the Norwegian settlers of Clayton and Winneshiek counties, Iowa, in the late forties and the fifties; the causes are everywhere principally economic. ”
