This is the fourth and final volume of the translation of Father Waclaw Kruszka's history of the Poles in the United States. Concentrating on the Polish settlements in the central states - Wisconsin, Minnesota, North and South Dakota, Nebraska, Iowa, Missouri and Kansas - and the far western states, Kruszka continues his study of the largest Slavic group of the turn-of-the-century immigration. The volume includes an extensive index of all volumes in the series.
