233      Employee  while  laying  a  switch  in  a  mine  sus-
319  tained  an  injury  to  his  back.    The  arbitrator  awarded


190    SEC.  8— (d)  "AVERAGE  AMOUNT  EARNED"

$14.00  a  week  for  nine  weeks.  On  review  the  Com-
mission allowed  $7.20  a  week  for  407  weeks,  or  sixty
per  cent  of  the  difference  in  his  earning  capacity,
he  having  two  children.  Employee  testified  that  he
could  earn  $18.00  after  the  injury.  Before  the  in-
jury he  made  $26.53.  The  Commission  fixed  present
earning  capacity  at  $14.25,  $12.42  less  than  he  was
able  to  earn  before  the  accident.  Held,  although  the
amount  actually  earned  since  the  injury  is  not  con-
clusive in  determining  the  reduction  of  earning  ca-
pacity, yet  where  it  is  the  only  competent  evidence
in  the  record  tending  to  show  the  extent  of  the  re-
duction in  earning  capacity,  it  is  error  on  the  part
of  the  Commission  to  ignore  it.  Old  Ben  Coal  Co.  v.

233  Where  the  temporary  partial  incapacity  for  work
for  which  an  award  is  made  arises  out  of  the  same
injury  which  caused  the  permanent  partial  loss  of
the  use  of  an  arm,  the  award  for  the  temporary  par-
tial incapacity  must  be  set  aside.  Slago  Coal  Co.
v.  Industrial  Commission,  293  111.  271,  272;  127  N.

"Average  amount  earned,  etc."

233  The  measure  of  the  compensation  under  this  par-
agraph is  fixed  at  one  half  the  difference  between
the  average  amount  earned  before  the  accident  and
the  amount  which  the  employee  is  earning  or  is
able  to  earn  in  some  suitable  employment  after  the
accident.  Voiqht  v.  Industrial  Commission,  297  111.
