The approval by the court of minutes entered in vacation or in term time, and adoption of the orders and decrees made by the clerk, may be evidenced by an order of the court approving such orders and decrees, excepting such as may be specified as not approved. It shall not be necessary to enter on the minutes of the court, in term time, any of said orders or decrees made in vacation or in term time, but the same, as entered in vacation or in term time, shall, by the approval of the court, become the acts of the court.
