QuillQuill, a term applied (1) to the hollow cylinder at the base of the shaft of a feather: and (2) to any of the larger wing feathers. Those of the goose, turkey, and swan were formerly the only material of writing-pens in the West, though the manufacture of quill pens has lost its importance since the introduction of steel pens. Pens made from crow quills are still used for drawing, and the name is given to a fine stool pen.
