Section 399. Children discharged from state institutions

The
  commissioner  of  social  services  shall  co-operate  with  the   state
  institutions   for   delinquent,   mentally   disabled   and  physically
  handicapped children to ascertain the conditions of  the  home  and  the
  character and habits of the parents of a child before his discharge from
  a  state institution, and make recommendations as to the advisability of
  returning said child to his home.  In case the  commissioner  of  social
  services  shall  deem  it  unwise to have any such child returned to his
  former home, such  state  institution  may,  with  the  consent  of  the
  commissioner,  place  such  child  into the care of said commissioner of
  social services.
