The train drew out of the great Van Buren Street depot at 4. 30 of a dark day in late October. A tall young man, with a timid look in his eyes, was almost the last one to get on, and his pale face wore a worried look as he dropped into an empty seat and peered out at the squalid buildings reeling past in the mist. The buildings grew smaller, and vacant lots appeared stretching away in flat spaces, broken here and there by ridges of ugly squat little tenement blocks. Over this landscape vast banners of smoke streamed, magnified by the misty rain which was driven in from the lake.
