At the time of said meeting, the board of directors shall hear any objections made by any interested person, and, if satisfied that any injustice has been done in the classification of the tracts of land, it shall correct the same in accordance with what is right, but, if not so satisfied, it shall leave the classification as first made and enter an order to that effect. Any person appearing and urging objections who is not satisfied with the decision of the board of directors may appeal its decision to the district court having original jurisdiction in the formation of said district within ten days after the decision of the board of directors was rendered by filing with the clerk of said court a statement in writing of his objections to the assessment made against him together with a bond with security conditioned to pay such taxes as may be finally levied upon the land in question and the costs occasioned by the appeal if the board of directors is sustained by said court.L. 23: p. 503, § 13.
