(2) At the first regular meeting of the district school board in each school district after the expiration of 60 days from July 1 in each year, the board shall make an order that all such warrants which have not been so presented for payment, describing them, shall be canceled. The board shall cancel all such warrants which were called for payment more than seven years prior to July 1 of that year.
