§ 123. Secretary of the board; commissioner of supplies. The board of
contract and supply shall appoint a secretary to hold office during its
pleasure, whose duty it shall be to keep a full journal of all the
proceedings of the board and to perform such additional duties as may be
required by the board, or by law or ordinance of the common council.
Where any work or repairs needed to be done, or materials or supplies to
be furnished for any office, court, board or department shall not exceed
two hundred and fifty dollars in cost, the board of contract and supply
may by general or special rule authorize the commissioner of public
works, or the commissioner of public safety, or the secretary of the
board, or any of them, to give written orders therefor and purchase the
same. No materials or supplies shall be purchased for, or delivered by
or upon the order of the commissioner to any officer, board, court, body
or department of the city, except upon the requisition in writing from
the officer, board, body or head of the department for which the same
are required. The commissioner shall require a receipt in writing from
each officer, board, body or head of the department for all supplies
delivered to him or it by the commissioner or on his order, and he shall
approve, in writing, all claims for any such materials or supplies
purchased by him, before the same shall be presented to the comptroller
for audit.
