The ballots used in all elections provided for in this Charter shall be without party marks or designations. The whole number of ballots to be printed for any election for any office shall be divided by the number of candidates for such office, and the quotient so obtained shall be the number of ballots in each series to be printed. The names of the candidates shall be arranged in alphabetical order and the first series of ballots printed. The first name shall then be placed last and the next series of ballots printed, and this process shall be repeated until each name shall have been first an equal number of times. These ballots shall then be combined into tablets with no two of the same order of names together. One space shall be left below the printed names of the candidates for each office to be voted for, wherein the voter may write the name of any person for whom they may wish to vote.
