Sect. 1. All Indians and descendants of Indians in this State are hereby placed on the same legal footing as the other inhabitants of the Commonwealth, excepting those who are supported, or have been, in whole or in part, by the State, and excepting also, those residing on the Indian plantations of the Chappequiddick, Christiantown, Gay Head, Marshpee, Herring Pond, Fall River, and Dudley tribes, or those whose homes are thereon and are only temporarily absent. Sect. 2. Any Indian or person of color, belonging to either of the tribes before mentioned, and residing within the limits of any town or city of this Commonwealth, to whom the right of citizenship is not extended by the first section of this act but who wishes to exercise that privilege, may certify the same in writing to the clerk of the town or city where he resides, who shall make record of the same: and upon paying a poll tax, he shall become, to all intents and purposes, a citizen of the State, and shall not, thenceforward, return to the legal condition of an Indian. And settlement shall be required, by those who become citizens, under the provisions of this act, in the same manner they are acquired by other persons, under the General Statutes of the Commonwealth. Sect. 3. It shall be the duty of the governor, by and with the advice and consent of the council, to appoint an able, discreet, and suitable person, to be Indian commissioner, who shall hold his office for the term of three years, unless sooner removed by the governor and council. And the governor and council shall fill all vacancies which shall happen in said office, by death, resignation, expiration of said term, or otherwise. It shall be the duty of said commissioner to exercise a careful supervision over the affairs of all the Indians of the Commonwealth, not endowed by the provisions of this act, with the rights of citizenship, and to aid them, by advice, counsel, and whatever other suitable means may be within his control, to promote their welfare, to improve their general condition, and to qualify themselves, judiciously, and with safety to themselves and others, to be placed, at as early a time as may be, on the same legal footing as the other inhabitants of the Commonwealth. He shall exercise all the powers, perform all the duties, and be subject to all the restrictions, responsibilities and liabilities, which now by law appertain to the treasurer of Marshpee, and to the guardians of other tribes except so far as they may be charged or varied by the provisions of this act; and he shall give bonds, to the satisfaction of the governor and council, for the faithful performance of such trust.
