  thereof, as  he  deems  necessary.  He  may  require  the  head  of  any
  administrative  unit  or  authorized  agency, or any officer or employee
  thereof, to  furnish  data  and  information  and  to  answer  inquiries
  pertinent  to  such review or investigation. Members of the committee of
  the board of supervisors designated or created to review  the  tentative
  budget  shall be entitled to investigate and make inquiry concerning the
  estimate of any administrative unit or the request for an  appropriation
  of  any  authorized agency. Such members shall be entitled to attend all

  estimates of the various administrative units and the  requests  for  an
  appropriation  of  the  several  authorized agencies, the budget officer
  shall prepare a tentative budget, accompanied by a budget message  where
  required  pursuant to section three hundred seventy-four. He shall cause
  to be printed or otherwise reproduced such  number  of  copies  of  such
  tentative  budget  and  such  budget  message,  if  any, as the board of
  supervisors shall direct. The tentative budget and the  budget  message,
  if  any,  together with the copies thereof, shall be filed by the budget
  officer with the clerk of the board of supervisors not  later  than  the
  fifteenth day of November.
