Duluth, Minn., Feb. 26. -- The mysterious biplane which circled over Superior, Wis., elevators holding grain to be shipped to England, France and Russia for nearly an hour and a half today, and then disappeared inthe direction of the United States Steel plant, west of Duluth, was being sought tonight by Superior and Duluth people.
Half a dozen employes of the Great Northern railway working in the shops near Allouez, described the aeroplane at length.
Several nights ago people in this city claimed to have seen moving lights in the sky and heard the explosions of a motor. There is no aeroplane known to be owned or operated in this district or on this side of the Canadian line.
One theory here is that these flights may be the operations of some amateur aviator who is trying out his machine, but who he is or where he is from, is not known here. But that an aeroplane flew over St. Louis Bay early today has been vouched for by many people.
