clip;  the  fourth  a  bicycle  bell,  etc.  The  task  of  the  subject ­
  is  to  take  the  object  in  each  compartment  and  assemble ­
  it.  Twenty  minutes  were  given  for  this  test  and
Ae  results  recorded  according  to  the  scale  of  values  worked
°ut  by  Professor  Stenquist.  The  object  of  this  test  was
to  discover  mechanical  ability.
This  experiment  was  conducted  in  two  sections.  In
the  first  section  all  but  the  last  of  the  tests  named  were
given  to  thirty-one  men  engaged  in  action  assembling.
the  second  section  of  the  experiment  all  the  tests  were
g ly en  to  fifty-one  finishing  assemblers  and  twenty-six
action  assemblers.  During  the  course  of  the  first  part  of
the  experiment,  all  the  assemblers  were  on  a  day-work
father  than  a  piece-work  basis,  and  for  this  reason  it  was
lrtl possible  to  obtain  an  objective  rating  of  the  men  based
°u  their  actual  production.  Therefore,  in  lieu  of  somening
  better,  each  foreman  was  asked  to  rank  the  men.
t  was  carefully  explained  to  him  that  his  ranking  should
^  based  upon  his  opinion  as  to  the  possible  production  of
men  if  they  were  allowed  to  work  on  a  piece-work
a sis.  The  fact  that  during  a  previous  drive  on  production
jfi°st  of  these  men  had  been  on  piece-work  made  it  possible
r  the  foreman  to  make  such  a  ranking  on  something  more
.  an  merely  hypothetical  grounds.  The  foremen’s  ranklr
 fgs  were  then  mathematically  compared  with  the  ranking
°  tbe  men  in  the  various  tests,  with  the  following  results:
