[180] States, in Charleston harbor and on Beaufort River, various forts and fortifications, and sites for the erection of forts, on the following conditions, viz.:
That, if the United States shall not, within three years from the passing of this act, and notification thereof by the Governor of this State to the Executive of the United States, repair the fortifications now existing thereon or build such other forts or fortifications as may be deemed most expedient by the Executive of the United States on the same, and keep a garrison or garrisons therein; in such case this grant or cession shall be void and of no effect.1It will hardly be contended that the conditions of this grant were fulfilled, and, if it be answered that the state did not demand the restoration of the forts or sites, the answer certainly fails after 1860, when the controversy arose, and the unfounded assertion was made that those forts and sites had been purchased with the money, and were therefore the property, of the United States. The terms of the cession sufficiently manifest that they were free—will offerings of such forts and sites as belonged to the state; public functionaries were bound to know that, by the United States law of March 20, 1794, it was provided “that no purchase shall be made where such are the property of a State.”2 The stipulations made by Virginia, in ceding the ground for Fortress Monroe and the Rip Raps, on March 1, 1821, are as follows:

Be it enacted by the General Assembly, That it shall be lawful and proper for the Governor of this Commonwealth, by conveyance or deeds in writing under his hand and the seal of the State, to transfer, assign, and make over unto the said United States the right of property and title, as well as all the jurisdiction which this Commonwealth possesses over the lands and shoal at Old Point Comfort and the Rip Raps: . . . 2. And be it further enacted, That, should the said United States at any time abandon the said lands and shoal, or appropriate them to any other purposes than those indicated in the preamble to this act, that then, and in that case, the same shall revert to and revest in this Commonwealth.3By accepting such grants, under such conditions, the government of the United States assented to their propriety, and the principle that holds
