§ 68. Treasurer and deputy treasurer. The treasurer may appoint, to
hold office during his pleasure, a deputy and such other subordinates as
may be prescribed by the board of estimate and apportionment. In case of
the absence or disability of the treasurer, or of a vacancy in the
office, the deputy shall discharge the duties of the office until the
treasurer returns, his disability ceases or the vacancy is filled. The
treasurer and deputy treasurer, before entering upon the discharge of
the duties of their respective offices, shall each execute and file with
the city clerk, an official undertaking in such penal sum as may be
prescribed by the common council. Such undertaking, when approved as
provided by law, shall have the same force and effect, and shall be
filed and recorded in the office of the county clerk of the county in
which the city is located in the same manner as is required in the case
of an undertaking of a town collector.
