The trustees shall choose
  from among their own number a chairman  and  vice-chairman.  They  shall
  from  time to time select such officers and employees, including a chief
  executive officer and such engineering, marketing and legal officers and
  employees, as they may require for the performance of their  duties  and
  shall  prescribe  the  duties  and  compensation  of  each  officer  and

  expenses, it shall incur no obligations  for  salary,  office  or  other
  expenses  prior  to  the  making  of appropriations adequate to meet the
  same.
