§ 23. Annual reports of departments. The several heads of departments
shall present to the mayor annually, on or before the first Monday of
December, a report of their proceedings during the preceding year. The
mayor shall transmit the same to the common council with any
recommendation he may think proper to make, but nothing in this section
contained shall be construed to relieve such heads of departments from
furnishing such other information as may be required by the mayor at any
time.
