ARTICLE IV
All grants of land heretofore made by either party, within the limits of the territory which by this treaty falls within the dominions of the other party, shall be held valid, ratified, and confirmed to the persons in possession under such grants, to the same extent as if such territory had by this treaty fallen within the dominions of the party by whom such grants were made; and all equitable possessory claims, arising from a possession and improvement of any lot or parcel of land by the person actually in possession, or by those under whom such person claims, for more than six years before the date of this treaty, shall, in like manner, be deemed valid, and be confirmed and quieted by a release to the persons entitled thereto, of the title to such lot or parcel of land, so described as best to include the improvements made thereon; and in all other respects the two contracting parties agree to deal upon the most liberal principles of equity with the settlers actually dwelling upon the territory falling to them, respectively, which has heretofore been in dispute between them.
