    "Two Rope" Square Knot
      Seldom. if e .... er, has the peculiar
    construction of the Square Knot (or
    Reef Knot) been properly analyzed.
    This knot can be formed solely b.,.· the
    union of two bights, nothing more.
    That's right - you usc: a bight.
      Take the exact center of the long
    rope, and form the center into a
    downward bight (fig.  1. )
      Take one end of the short (ten
    inch) rope and insert it through the            fig.  1
    bight from front to back, and right to
    left. Then, carry it across in front of
    the neck and narrow portion of the
    bight (fig. 2.)
      Thrust that same end through the   ="''''' .... '~ ........
    hight, this time from front to back,                '\
    bringing it out the left side of the
    hight, as you view it (fig. 3.)
      Get the short rope "middled" and
    pull the ends of both ropes. The
    result is instantaneous and obvious              fjg.2
    (fig. 4).  You have a Square Knot
    formed by two bights.
       Note that the ropes hold strongly
     in that position. Nothing could be
     stronger at the middle of a rope. If
                                    .4>'
     they cause trouble, it's always when   " ... "" ... ~--
     an end is too dose.
       You will observe, too, that the
     bights can be loosened by simply
     pushing them toward each other. The
     operation of this knot, so simplified,
     is of value in the study of the more            fig.  3
     complicated knots that will now be
     discussed.
