Professor R. B. Anderson, in his book on the early Norwegian immigration[40] puts religious persecution as the primary cause of emigration from Norway. I cannot possibly believe that even in the immigration of the first half of the nineteenth century religious persecution was, except in a few cases, the primary or even a very important cause in the Scandinavian countries. 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. But letters written by pioneers and by those about to emigrate testify amply to the fact that it was the hard times that was the chief cause. And the same applies almost as generally to the Swedes; among the Danes the economic factor has not operated so extensively, though here, also, it was the preponderating cause. [40] _First Chapter, etc._ A Norwegian journal, _Billed-Magazin_, published in Chicago in 1869-70 and edited by Professor Svein Nilsen, offers much that throws light on this question. It contains brief accounts of the early Norwegian immigration and the earliest settlements, a regular column of news from the Scandinavian countries, interviews with pioneers, etc. In one interview, Ole Nattestad, who sailed in 1837 from Vægli, Numedal, and became the founder of the fourth Norwegian settlement in America, that of Jefferson Prairie in Rock County, Wisconsin, and the neighboring Boone County in Illinois, describes his experience as a farmer in Numedal and how the difficulty of making any headway finally drove him to emigrate to America.[41] The statement of another pioneer I quote in its entirety.[42] It is that of John Nelson Luraas, who came from Tin in Telemarken, to Muskego, Wisconsin, in 1839, and in 1843 moved to Dane County, Wisconsin. He says:
