THE  PORTABLE  LABORATORY  6$
mdd  interest  and  some  jocular  remarks.  After  that,  nothln
 g  more  is  said.
When  a  man  is  to  be  examined,  he  is  simply  informed
that  it  is  his  turn,  his  work  ticket  is  stamped  to  show  at
w hat  time  he  stops  work—all  subjects  are  paid  out  of  a
special  cost  account  for  the  time  occupied  by  psychological
laminations,  and  special  care  is  taken  to  make  this  pay
generous—and  he  is  then  conducted  into  the  laboratory,
^ere  he  is  properly  seated  and  the  necessary  tests  are
§ 1Ve n  to  him.  In  all  cases,  tests  to  men  are  given  by  a
male  examiner,  and  as  far  as  possible,  all  tests  given  to
w ornen  are  given  by  a  woman  examiner.  Since  this  work
has  become  established,  this  is  done  without  exception.
Ahere  women  or  girls  are  given  tests  by  a  male  examiner,
some  woman  in  the  shop,  well  known  to  all  the  girls,  is
chosen  to  accompany  each  subject.  The  door  of  the  laboratory ­
  is  left  part  way  open,  and  this  woman  sits  just
°utside  where  she  can  observe  the  process  of  the  examinati°n.
  This  precaution,  while  not  absolutely  essential,
tlev ertheless  serves  to  forestall  any  possible  embarrassment ­
  on  the  part  of  the  girl  being  examined,  and  consequently ­
  contributes  to  the  reliability  of  the  results  of  the
tests.  When  the  examination  is  conducted  by  a  woman,
™ s  precaution  is  naturally  unnecessary.
The  use  of  this  laboratory  has,  on  the  whole,  been  quite
satisfactory.  It  serves  the  purposes  for  which  it  is  intended ­
  admirably.  It  is  convenient;  it  can  be  set  up  or
taken  down  very  quickly—in  three  minutes  to  be  exact;
m  fits  well  into  any  available  space  in  the  shop;  it  is  intensive; ­
  it  saves  an  enormous  amount  of  time  which
'''Quid  otherwise  be  consumed  by  having  the  necessary
subjects  come  some  distance  to  a  more  remote  stationary
Moratory  for  examination.
