Quill
or QUILLE, in ornithology, the larger and stronger feathers of the wing. They are of three kinds : primaries, secondaries, and tertiaries. In music, a small piece of quill attached to a piece of wood, by means of which certain stringed instruments, as the virginal, were played. In seal engraving, the hollow mandrel of the lathe or engine used by the seal engraver. In weaving , a small spindle, pirn, or rod upon which thread is wound to supply the shuttle with the woof, we weft, or filling, as it variously called, and which crosses the warp, or chain.
