Massachusetts Constitution Pt. 2, Ch. I, § 3, Art. 2

ART. II. [And in order to provide for a representation of the citizens of this commonwealth, founded upon the principle of equality, every corporate town containing one hundred and fifty ratable polls, may elect one representative: every corporate town, containing three hundred and seventy-five ratable polls may elect two representatives: every corporate town containing six hundred ratable polls, may elect three representatives: and proceeding in that manner, making two hundred and twenty-five ratable polls, the mean increasing number for every additional representative.

Provided nevertheless, that each town now incorporated, not having one hundred and fifty ratable polls, may elect one representative: but no place shall hereafter be incorporated with the privilege of electing a representative, unless there are within the same one hundred and fifty ratable polls.]

And the house of representatives shall have power from time to time to impose fines upon such towns as shall neglect to choose and return members to the same, agreeably to this constitution.
