When  the  profit-making  aspect  of  the  business  is  examined,  it  will  be  found
that  the  interstate  element  is  still  further  magnified.  The  vast  investment  of
capital  which  has  been  made  in  it  is  required,  among  other  things,  in  order  to
provide  a  place  at  which  the  teams  in  the  league  may  play  their  contests.  Each
club  has  a  ball  park,  with  stands  erected  upon  them,  sometimes,  as  in  the  case
of  a  major  league  club,  costing  several  millions  of  dollars.  Every  club  in  the
league  earns  its  profit  not  only  by  the  drawing  capacity  of  its  team  at  home,
but  also  by  that  of  the  teams  of  the  clubs  which  its  team  visits  in  the  various
cities  in  the  league.  The  gate  receipts  in  all  of  the  cities  in  which  the  clubs  are
located  are  divided  according  to  a  definite  proportion,  fixed  by  agreement
between  the  club  of  the  city  in  which  the  game  is  played  and  the  club
employing  the  visiting  team.
In  no  other  business  that  can  now  be  recalled  is  there  such  a  close  interrela-
tionship and  interdependence  between  persons  in  one  State  and  persons  in
another.  The  personality,  so  to  speak,  of  each  club  in  a  league  is  actually  pro-
jected over  state  lines  and  becomes  mingled  with  that  of  the  clubs  in  all  the
other  States.  The  continuous  interstate  activity  of  each  is  essential  to  all  the
others.  The  clubs  of  each  league  constitute  a  business  unit  embracing  territori-
ally a  number  of  different  States.  While  each  club  has,  of  course,  a  local  legal
habitat,  yet  from  a  practical  business  standpoint  is  is  primarily  an  ambulatory
organization.
