Members of the jury of view must take the following oath before assuming their duties: “I do solemnly swear that I am not directly interested in the construction of the proposed ditch, either as the owner or otherwise, or in adjacent land lying within one mile of the proposed ditch, and that I am not related to any person who is so interested. I further swear that I have no bias or prejudice toward any person directly interested in the ditch, and that I will assess the amount of expense due on and by all adjacent lands lying within one mile of the ditch, according to law, without fear, favor, hatred, or hope of reward, to the best of my knowledge and ability. So help me God.”
