The clerk of the circuit court shall, within ten days after the adjournment of each term of court, record the indictments returned into court in a well-bound book to be kept for that purpose which shall be styled “Secret Record of Indictments,” and which shall be properly indexed and kept secret. If the office of the clerk be furnished with an iron safe or vault, the book shall be kept therein when not in actual use. If an indictment be lost or destroyed, the accused may be tried on a certified copy of the indictment made from the said record-book.
