Mr. Justice BALDWIN delivered the opinion of the Court:

At the January term of this Court, 1832, the plaintiff filed a bill in equity, presenting a case arising under the various charters from the crown of England to the Plymouth Company, in 1621; to Massachusetts in 1629; to Rhode Island in 1663; the new charter to Massachusetts in 1691; together with sundry intermediate proceedings of the council of Plymouth: the result of which was to vest in the colony of Massachusetts and the king, all the rights of propriety and government previously granted to that company as a political corporation. The bill also set out the repeal of the original charter of Massachusetts on a scire facias in the court of chancery in England, the grant by the crown and acceptance by the colony of a new charter, subsequent to the charter to Rhode Island.

Rhode Island v. Massachusetts (37 U.S. 657)/Opinion of the Court

All these acts are specially and at large set out in the bill, but need not in this stage of the cause be referred to by the Court in detail. They present the claim of the plaintiff to the territory in controversy between the two states, in virtue of these charters, according to the boundaries therein described.

Rhode Island v. Massachusetts (37 U.S. 657)/Opinion of the Court

Independently of the claim under the charter of 1663, the plaintiff asserts a previous right in virtue of grants from the Indians, and settlements made under a title thus acquired; and also asserts, that under both titles, the inhabitants of Rhode Island made settlements on the lands immediately south of the boundary between the two colonies as now asserted; which settlements were so made and continued from the time of the purchase from the Indians, before, under the charter, and afterwards, though the line was not defined and disputed.

Rhode Island v. Massachusetts (37 U.S. 657)/Opinion of the Court

The bill then proceeds to state the existence of controversies between the two colonies, at a very early period; to settle which commissioners were appointed by each colony in 1709, and at various other periods down to 1809; and sets forth the proceedings of the commissioners of the colonies before the revolution, and the states afterwards, down to 1818.

For the present purposes of this case, it is necessary to refer only to one subject matter of these proceedings during this whole period, which is presented in the bill in the same aspect throughout; that subject is the agreement of 1709, and 1718; and the acts done pursuant thereto, which are recited at large in the bill. It then states the agreement of the commissioners of the two colonies, that a line should be run and marked as their boundary, which was done; a survey made and returned, together with all the proceedings to the legislatures of the respective colonies, accepted by Massachusetts, but as the bill avers, not accepted and ratified by Rhode Island. This is the line now claimed by Massachusetts; and whether the charter line or that, is the true line of right and boundary between the two states, is the only point in controversy in this case.

The bill avers that this line was agreed on in consequence of a representation by the Massachusetts' commissioners to those of Rhode Island, that in 1642, Woodword and Saffrey has ascertained the point three miles south of Charles river; which, by the charters of both colonies, was to form their common boundary by line to run east and west therefrom. That Woodword and Saffrey had set up a stake at that point on Wrentham Plains, as the true southern boundary of Massachusetts. That the Rhode Island commissioners, confiding in such representation, believing that such point had been truly ascertained, and that such stake was no more than three miles from Charles river, south; entered into and made the agreement of 1710-11, which was executed by the commissioners on both sides.

In the agreement is this clause: That the, stake set up by Woodword and Saffrey, approved artists, in 1642, and since that often renewed, in lat. 41°55' N., being three English miles south of Charles river, in its southernmost part, agreeably to the letters patent to Massachusetts, be accounted and allowed as the commencement of the line between the colonies, and continued between them as decyphered in the plan of Woodword and Saffrey, on record in the Massachusetts government.
