The passenger trains and the freight trains are set in motion by the same ultimate economic fact. Our exports are all bulky and require more tonnage than our imports. On the westward trip, consequently, bunks are erected and men are brought in space where cotton, wheat, etc., were taken out. The tariff, by so much as it lessens the import of goods, leaves room which the ship owners are eager to fill with immigrants. To do this they lower the rates. Hence the tariff is a premium on immigration. The protectionists have claimed that the tariff does favor immigration. But nine-tenths of the immigrants are laborers, domestic servants, and farmers.^[1] Probably more than one-third of the total number, including women, find their way to the land.
