A term for stiff-bristled brushes that apply scumble (see Glossary the term was also a self-assigned name of a group of Bucks County, Pennsylvania artists who, from 1900 to 1920, regularly spent their summers together in Edison, near Doylestown in Bucks County. The area was noted for picturesque scenery and distinguished by a seven-arched stone bridge, dating from 1821, which crossed the Neshaminy River. Artist members who have been identified as "Scumblers" include Winfield Bardsley, Clive Clevenger, Louis Dougherty, William Hofstetter, Ellis Oliver, Charles Grafly, and John Ramsey Conner. Many of these visitors were lodged at Turk's Head Tavern in Edison, but the place where they socialized and did indoor painting was called "The Shack", a structure on property near Neshaminy Creek.
