                                      VARIOUS DIRECT METHODS FOR TYING TURK'S-HEADS

                                             1361.  There  are  a  number  of  direct  ways  by  which  TURK's-



                                      HEADS  that  do  not  lend  themselves  readily to  one  of the  "enlarge-




                                      ment"  methods that have  been given, may be tied.




                                            The  projection  of a  TURK'S-HEAD  on  a  plane  has  certain  advantages.



                                     It is easy to plan, easy to form, and the whole knot is  visible  at all  times.                                                                                                                                                                                                                                                                                                               10



                                     But it is  not so  easy to work as  a TURK'S-HEAD  that has been tied around




                                      a cylinder,  as  the  knot is  distorted by having one rim much larger  than



                                     the other. This is not always important and there are certain complicated



                                      knots  that can  hardly be  projected by another method.  (See  jIj? 1394  and




                                      ~ 39S.)  For regular knots, a large disk may be used with radiating lines

                                      and  equispaced  circles  about  the  center  and  with  pins  at  all  crossings,



                                      around which different-sized TURK'S-HEADS  may be tied.

                                             1362.  Take  a  twenty-fIve-cent  piece,  place  it  in  the  center  of  a



                                     sheet of paper, and pencil a  line around it. Divide the circumference




                                      with a  pair of dividers into a  number of parts equal to the intended




                                      number of bights.



                                            Make  a  series  of regular  triangles  around  the  outside  of  the  circum-




                                      ference  just  made,  using  the  ends  of each  arc  to  limit  one  side  of  each



                                      triangle.  From  each  apex  of  these  triangles,  draw  two  divergent  legs,



                                      each foot of which  meets the foot of its  neighbor. This completes a  di-

                                      continue  to  add  other  legs  in  the  same  manner.  When  certain  that  the



                                      diagram consists of only one line  (the number of bights and leads have no



                                      common  divisor),  you  are  ready  to  tie  the  knot.  But  if  the  diagram  rs



                                      found  to consist of more  than  one line,  add  another tier of legs.

                                      is  to use the system of notation that has  been described in  Chapter
