BURR-PUMP, or BILGE-Pump, differs from the common pump, in having a staff, six, seven, or eight 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 six, eight, or ten to hale by, thus pulling it up and down.
