Roald Amundsen, the famed Norwegian polar explorer who had discovered the South Pole in 1911, addresses a large audience in Duluth about the on-going battle of World War I and appeals to the people of the United States, especially American labor, to "stand behind the President to the last ditch, and to work with 100 per cent efficiency to the end of the war." After remarking that "Norwegians in this country will be pleased to know after the war that they, too, have had a share in the liberation of mankind," Amundsen would continue on a speaking tour of Minnesota and later leave for Norway to prepare for a North Pole expedition.
