This is believed to be one of the only surviving intact bell mops. These unique objects hung in the boiler rooms of steamboats for workers to wipe grease off their hands. Bell mops were used until so filthy with coal dust and oils, they were thrown into the river, never to be seen again. This mop survived thanks to beloved river historian Ruth Ferris, who made a habit of preserving river history by collecting memorabilia like this. A tradition developed on the Mississippi River for engineers and their assistants to craft decorative macramé hangers for their bell mops. Crews competed between boats to create the most elaborate pieces. This example, which is on display in the Pott Curator's office, hung in the boiler room of the steamer Golden Eagle. ca. 1940. Made of cord, knotted, plaited, and painted.
