n. A pipe or tube through which missiles are blown by the breath. Those used by certain Indians of South America are of wood, from 7 to 10 feet long, with a bore not larger than the little finger; through them are blown poisoned arrows made of split cane or other light material, from a foot to 15 inches in length, and wound at the butt with some fibrous material so as to fit the bore of the blow-gun. A similar blow-gun is in use among the Dyaks of Borneo. Also called blow-tube, and blowpipe.
