§ 144. Suspension of free passage through Saint Marys Falls Canal; tolls
With a view of securing reciprocal advantages for the citizens, ports, and vessels of the United States, whenever and so often as the President shall be satisfied that the passage through any canal or lock connected with the navigation of the Saint Lawrence River, the Great Lakes, or the water ways connecting the same, of any vessels of the United States, or of cargoes or passengers in transit to any port of the United States, is prohibited or is made difficult or burdensome by the imposition of tolls or otherwise which, in view of the free passage through the Saint Marys Falls Canal, permitted to vessels of all nations, he shall deem to be reciprocally unjust and unreasonable, he shall have the power, and it shall be his duty, to suspend by proclamation to that effect, for such time and to such extent (including absolute prohibition) as he shall deem just, the right of free passage through the Saint Marys Falls Canal, so far as it relates to vessels owned by the subjects of the Government so discriminating against the citizens, ports, or vessels of the United States, or to any cargoes, portions of cargoes, or passengers in transit to the ports of the Government making such discrimination, whether carried in vessels of the United States or of other nations.
In such case and during such suspension tolls shall be levied, collected, and paid as follows, to wit: Upon freight of whatever kind or description, not to exceed $2 per ton; upon passengers, not to exceed $5 each, as shall be from time to time determined by the President: Provided, That no tolls shall be charged or collected upon freight or passengers carried to and landed at Ogdensburg, or any port west of Ogdensburg, and south of a line drawn from the northern boundary of the State of New York through the Saint Lawrence River, the Great Lakes, and their connecting channels to the northern boundary of the State of Minnesota.
