Mass. Const. pt. 2, ch. I, § II, art. II

The senate shall be the first branch of the legislature; and the senators shall be chosen in the following manner, viz. there shall be a meeting on the [first Monday in April], [annually], forever, of the inhabitants of each town in the several counties of this commonwealth; to be called by the selectmen, and warned in due course of law, at least seven days before the [first Monday in April], for the purpose of electing persons to be senators and councillors; [and at such meetings every male inhabitant of twenty-one years of age and upwards, having a freehold estate within the commonwealth, of the annual income of three pounds, or any estate of the value of sixty pounds, shall have a right to give in his vote for the senators for the district of which he is an inhabitant.] And to remove all doubts concerning the meaning of the word "inhabitant" in this constitution, every person shall be considered as an inhabitant, for the purpose of electing and being elected into any office, or place within this state, in that town, district or plantation where he dwelleth, or hath his home.

The selectmen of the several towns shall preside at such meetings impartially; and shall receive the votes of all the inhabitants of such towns present and qualified to vote for senators, and shall sort and count them in open town meeting, and in presence of the town clerk, who shall make a fair record, in presence of the selectmen, and in open town meeting, of the name of every person voted for, and of the number of votes against his name: and a fair copy of this record shall be attested by the selectmen and the town clerk, and shall be sealed up, directed to the secretary of the commonwealth for the time being, with a superscription, expressing the purport of the contents thereof, and delivered by the town clerk of such towns, to the sheriff of the county in which such town lies, thirty days at least before [the last Wednesday in May] [annually]; or it shall be delivered into the secretary's office seventeen days at least before the said [last Wednesday in May]: and the sheriff of each county shall deliver all such certificates by him received, into the secretary's office, seventeen days before the said [last Wednesday in May].

And the inhabitants of plantations unincorporated, qualified as this constitution provides, who are or shall be empowered and required to assess taxes upon themselves toward the support of government, shall have the same privilege of voting for councillors and senators in the plantations where they reside, as town inhabitants have in their respective towns; [and the plantation meetings for that purpose shall be held annually on the same first Monday in April], at such place in the plantations respectively, as the assessors thereof shall direct; which assessors shall have like authority for notifying the electors, collecting and returning the votes, as the selectmen and town clerks have in their several towns, by this constitution. And all other persons living in places unincorporated (qualified as aforesaid) who shall be assessed to the support of government by the assessors of an adjacent town, shall have the privilege of giving in their votes for councillors and senators in the town where they shall be assessed, and be notified of the place of meeting by the selectmen of the town where they shall be assessed, for that purpose accordingly.
