“ The wall-knot is so made with the lays of a rope that it cannot slip, and serves for sheets, tacks, and stoppers. Knots are generally used to act as a button, in preventing the end of a rope from slipping through the hole of a dead-eye, or through the turns of a laniard, by which they are sometimes made fast to other ropes.—Knot also implies a division on the log line, bearing a similar proportion to a mile, which half a minute does to an hour ”
