Those persons who shall be qualified to vote for senators and representatives within the several towns of this commonwealth, shall, at a meeting to be called for that purpose, on the [first Monday of April annually], give in their votes for a governor, to the selectmen, who shall preside at such meetings; and the town clerk, in the presence and with the assistance of the selectmen, shall, in open town meeting, sort and count the votes, and form a list of the persons voted for, with the number of votes for each person against his name; and shall make a fair record of the same in the town books, and a public declaration thereof in the said meeting; and shall, in the presence of the inhabitants, seal up copies of the said list, attested by him and the selectmen, and transmit the same to the sheriff of the county thirty days at least before the [last Wednesday in May]; and the sheriff shall transmit the same to the secretary's office, seventeen days at least before the said [last Wednesday in May]; or the selectmen may cause returns of the same to be made to the office of the secretary of the commonwealth, seventeen days at least before the said day; and the secretary shall lay the same before the senate and the house of representatives, on the [last Wednesday in May], to be by them examined: and in case of an election by a [majority] of all the votes returned, the choice shall be by them declared and published. But if no person shall have a [majority] of votes, the house of representatives shall, by ballot, elect two out of four persons who had the highest number of votes, if so many shall have been voted for, but, if otherwise, out of the number voted for; and make return to the senate of the two persons so elected; on which the senate shall proceed, by ballot, to elect one, who shall be declared governor.
