Mass migration under sail

the long version

"Dr. Cohn provides an in-depth and comprehensive analysis of the economic history of European immigration to the antebellum United States, using and evaluating the available data as well as presenting new data. This analysis centers on immigration from the three most important source countries - Ireland, Germany, and Great Britain - and examines the volume of immigration, how many individuals came from each country during the antebellum period, and why those numbers increased."--Jacket.
