Any freeholder feeling aggrieved at the location of any portion of said boundary line may, within twenty days from the filing of said boundary with the county clerk, appeal to the board of directors, who shall, after due notice to the complainant, hold a session at some convenient place in the county in which the disputed boundary is located. At this session they shall hear all the evidence upon which such appeal is founded, as well as the evidence in favor of the location already made, and render such decision as they may find best subserves the ends of justice; and if any change be made in said boundary as a result of the hearing, such change shall be forthwith reported to the county clerk of the county in which such change is made.
