Every ordinance shall, upon its taking effect as herein provided, be recorded in a book kept for that purpose by the clerk. Such records shall include the signature of the president, attestation of the clerk and the mayor's written approval, or in case of his disapproval a memorandum of its passage over his veto; or in case the ordinance took effect because he failed to approve or disapprove and return within ten days, then a memorandum to that effect. Such record or a certified copy thereof, shall be presumptive evidence of the passage of the ordinance and of the facts certified. The original engrossed ordinances for each year shall be bound together and kept in the custody of the clerk.
