When any claim of any person against a county is disallowed, in whole or in part, by the board of county commissioners, such person may appeal from the decision of such board to the district court for the same county by causing a written notice of such appeal to be served on the clerk of such board within thirty days after the making of such decision and executing a bond to such county, with sufficient security, to be approved by the clerk of said board, conditioned for the faithful prosecution of such appeal and the payment of all costs that are adjudged against the appellant.
