Section 235. Officers, expenses and assistance

The commission shall elect
  annually, a chairman from its own members. It shall have the  power  and
  authority  to  employ  experts,  clerks, and a secretary, and to pay for
  their services and such other expenses as may be necessary  and  proper,
  not exceeding, in all, the annual appropriation that may be made by said
  city  or  village  for said commission. The body creating the commission
  shall by ordinance or resolution provide what compensation if any,  each
  of   such   commissioners   shall  receive  for  his  services  as  such
  commissioner.  Each city and incorporated village is  hereby  authorized
  and  empowered  to  make  such  appropriation as it may see fit for such
  expenses and compensation, such  appropriations  to  be  made  by  those
  officers  or  bodies  in  such  city  or  village  having  charge of the
  appropriation of the public funds.
