"Sea Wing," was fishing with S. H. Davis, of Detroit, when they saw on the lake what they thought was a ship, about 13 m long, with a canopy. A man, about 25 years old, wearing a hunting jacket and a cap, was fishing from the deck of the object. Near him were a woman and a 10-year old child. When the "Sea Wing" came close to the craft, a large, colored bal- loon rose from the object, which flew up with it to an altitude of about 150 m and circled "like a hawk" before flying away.
