(3) Instructions to voters. There shall be no indication on the ballot of a definite number of candidates to be voted for. The instructions to voters shall read as follows:
INSTRUCTIONS
Mark Your Choices with NUMBERS Only.
(Do NOT use X Marks.)
Put the number 1 in the square opposite the name of your first choice.
Put the number 2 opposite your second choice, the number 3 opposite your third choice, and so on. You may mark as many choices as you please.
Do not put the same number opposite more than one name.
To vote for a person whose name is not printed on this ballot, write his name on a blank line under the names of the candidates and put a number in the square opposite to show which choice you wish to give him.
If you tear or deface or wrongly mark this ballot, draw lines across its face to prevent its being used, return it and obtain another.
