The river Mississippi shall, however, according to the treaty of peace, be entirely open to both parties; and it is further agreed, that all the ports and places on its eastern side, to whichsoever of the parties belonging, may freely be resorted to and used by both parties, in as ample a manner as any of the Atlantic ports or places of the United States, or any of the ports or places of His Majesty in Great Britain All goods and merchandize whose importation into His Majesty's said territories in America shall not be entirely prohibited, may freely, for the purposes of commerce, be carried into the same in the manner aforesaid, by the citizens of the United States, and such goods and merchandize shall be subject to no higher or other duties than would be payable by His Majesty's subjects on the importation of the same from Europe into the said territories.
And in like manner all goods and merchandize whose importation into the United States shall not be wholly prohibited, may freely, for the purposes of commerce, be carried into the same, in the manner aforesaid, by His Majesty's subjects, and such goods and merchandize shall be subject to no higher or other duties than would be payable by the citizens of the United States on the importation of the same in American vessels into the Atlantic ports of the said States.
And all goods not prohibited to be exported from the said territories respectively, may in like manner be carried out of the same by the two parties respectively, paying duty as aforesaid. No duty of entry shall ever be levied by either party on peltries brought by land or inland navigation into the said territories respectively, nor shall the Indians passing or repassing with their own proper goods and effects of whatever nature, pay for the same any impost or duty whatever.
