The commission may make, alter, amend and repeal rules and regulations for the protection, regulation and control of such parks, and the roads, driveways, sidewalks, paths, lakes, pools, fountains, trees, flowers, shrubs, statuary, buildings and other things contained therein, and may prescribe penalties for the violation thereof. Any such penalty shall not be more than one hundred dollars ($100.00) or less than two dollars ($2.00) but it need not be for a specific amount; and the commission may provide that the penalty shall be in such amount, not less than one given sum nor greater than another given sum, as may be fixed by the court in its discretion. The commission may sue for and collect the penalty so fixed in a civil action in any court of competent jurisdiction. All fines and penalties recovered shall be used by the commission for the same purposes and in the same manner as its other funds. Such rules and regulations shall not take effect until ten days after their adoption by the commission and after their publication once a week for two weeks in at least five newspapers circulating in the county.
