It was falling dusk and the long emigrant train was clattering, close-packed with its load of somewhat frowsy humanity, through the last of the pine forest which rolls westward north of the Great Lakes toward the wide, bare levels of Manitoba, when Alison Leigh stood on the platform of a lurching car.
