BURR-PUMP, or BILDOX-PUMP, differs from the common pump, in having a staff 6, 7, or 8 feet long, with a bar of wood, whereto the leather is nailed, and this serves instead of a box. So two men, standing over the pump, thrust down this staff, to the middle whereof is fastened a rope, for 6, 8, or 10 to hale by, thus pulling it up and down.
