each  box  and  how  he  wishes  it  strapped  and
packed,  in  accordance  with  the  transportation
which  he  will  have  available  at  the  time  the
goods  arrive.  Obviously  a  llama  or  burro
cannot  carry  as  heavy  a  load  as  a  mule,  and  the

cases  may  be  carried  suspended  from  poles  between ­
  two  mules.
Follow  these  shipping  instructions  to  the

road  that  must  be  traveled.  Do  not  let  the  superior ­
  judgment  of  your  shipping  clerk  alter
