delivered the opinion of the court.
This case comes from fcbe Circuit Court for tbe Northern District of Illinois. It was heard there and decided on demurrer to the bill of complaint. The substance of the bill is this: That by various - acts of her legislature, commencing with one passed in February, 1867, the State of Illinois adopted measures for improving the navigation of Illinois Fiver, including the construction of a lock and dam at ITenry, and at Copperas Creek on the river. She created a board of cahal .commissioners, and invested it with authority to superintend the construction of the locks and dams-, to control and manage them after their construction, and to prescribe reasonable rates of toll for the passage of vessels through the locks. By a clause in one of the acts it was provided that all tolls received for the use of the locks, not necessary to keep the same in repair, and to pay the expenses of their collection, should be “ paid quarterly into the State treasury as' part of the general revenue of the State.” Laws of Illinois of 1872, 213, 214.
The works were constructed at an expense of several hundred thousand dollars, which was principally borne by the State. It is represented that a small portion was contributed ' by 'the United States. Those at Henry were completed in 1872; those at Copperas Creek in 1877; and the commissioners prescribed rates of toll- for the passage of vessels -through the locks, the rates being fixed per ton, according to the tonnage measurement of the vessels and the amount of freight carried.
The complainants, citizens of Illinois, composing the firm of Huse, Loomis & Co., are engaged, and have been, since their organization in 1864, in cutting ice at Peru and at other points on the Illinois River, and in transporting it on that river, and thence by the Mississippi and other navigable streams to St.Louis, Memphis, and other Southern markets; and in connection therewith are carrying on a general transportation business, using constantly from three to' six steamboats, and from thirty to sixty barges, varying from 125 to 1000 tons, all *545 licensed and registered under tbe act of Congress. They allege in the bill, that prior to the construction of the dam across the Illinois Biver at Henry, they were able to navigate the river Avithout interruption, except, such as Avas incident to its ordinary use in its natural state; that the dams at that place and at Copperas Creek are impediments to the free na.vir gation of the river; that while an additional depth of Avater is created above them, no practical advantage ensues to the complainants, for they encounter below the dams the same stage of Avater they Avould have Avithout them ; that the dams are so constructed as to wholly impede, except at extreme high Avater, the navigation .of the riArer by' steamboats and other vessels which were previously accustomed to navigate it, unless they pass through the locks; that from the construction of the lock and dam at Henry in 1872 to the spring of 1878, they have paid as duties or charges upon the tonnage measurement of their steamboats and other A^essels about three thousand dollars, and for tolls imposed upon the cargoes of ice transported by them about five thousand dollars; that upon subsequent shipments similar charges have been exacted, as also for the passage of their boats and barges through the lock at Copperas Creek. And they allege that they are advised and believe that the imposition of the tolls and tonnage duties mentioned is in violation: first, of the provision of article four of the ordinance for the government of the territory of the United States northwest of the Ohio Bfver, passed July 18, 1787, which provides, that “the navigable waters, . leading into the Mississippi and St. LaAvrence, and the carrying places between the same, shall be common highways, and forever free, as Avell to the inhabitants of the said territory as to the citizens of the Nnited States, and those of any other-States that may be admitted into the confederacy, Avithout' any tax, ihipost, or duty therefor; ” and, second, of thenar tide of the Constitution of the United States Avhich prohibits the imposing of a tonnage duty by any State without the consent, of Congress. Art. 1, § 10. They, therefore, pray that the-defeildants, who are canal commissioners, and all persons-, acting under them, may be restrained'from exacting any ton *546 nage duties or other charges for the. passage of their steam- , boats or barges, and other vessels used by them in navigating the Illinois Elver, or from interfering in any manner with the free and uninterrupted navigation of the river by them in the usual course of their business.
The questions thus urged upon the consideration of the court below are pressed here; but they are1 neither new nor difficult of solution: The opinion of that court presents in a clear and satisfactory manner the full answer to them, and nothing can be added to the force of its reasoning. In affirming its conclusions, we can do little more than repeat its argument. Hu se v. Glover, 11 Bissell; 550.
The fourth section of the ordinance for the government of the northwestern territory 'was the subject of consideration in
Escanaba Co.
v. Chicago,
*547
We also held, in that case, that, independently of these considerations, the terms of the ordinance were not violated because the navigable streams were subject to such crossings as the public necessities and convenience might require. The . rivers did not change their character as common highways, if the crossings were allowed under reasonable conditions, and so as not unnecessarily to obstruct them. The erection of bridges with dams, and the establishment of ferries for the transit of persons and property, are consistent with the free navigation of the rivers; and in suppoi t of this doctrine we referred to the case of
Palmer
v.
Cuyahoga
County,
Since the decision in the Escanaba case, we have had our attention repeatedly called to the terms of this clause in the ordinance of 1787. A similar clause as to their navigable rivers is found in the acts providing for the admission of California, Wisconsin, and Louisiana. The clause in the act providing for the admission of California was considered in
Cardwell
v.
American Bridge Company,
The exaction of tolls for passage through the locks is as compensation for the use of artificial facilities constructed, not as an impost upon the navigation of the stream. The provision of the clause that the navigable streams should be highways without any tax, impost, or duty, has .reference to their navigation in their natural state. It did not contemplate that such navigation might not be improved by artificial means, by the removal of obstructions, or by the making of dams for deepening the waters, or by turning into the rivers waters from. other streams to increase their depth. For outlays caused by such works the State may exact reasonable tolls. They are like charges for the use of wharves and docks constructed to facilitate the landing of persons and. freight, and the taking them on board, or for the repair of vessels.
The State is interested in the domestic as well as in the inter-state and foreign commerce conducted on the Illinois Biver, and to increase its facilities, and thus augment its growth, it has full power. It is only when, in the judgment of Congress, its action is deem'ed to encroach upon the navigation of the river as a means of inter-state and foreign commerce, that that body may interfere and control or supersede it. If, in the opinion of the State, greater benefit would- result to her commerce by thé improvements made, than by leaving the river in its natural state — and on that point the State must necessarily’determine for itself — it may authorize them, although increased inconvenience and expense may
*549
thereby result to the business of individuals. The private inconvenience must yield to the public good. The opening of a new highway, or the improvement of an old one, the building of a railroad, and many other works, in which the public is interested, may materially diminish business in certain quar-' ters and increase it in others; yet, for' the loss resulting, the sufferers have no legal ground of complaint. How the highways of a State, whether on land or by water, shall be best improved for the public good is a matter for State determination, subject always to the right of Congress to interpose in the cases mentioned.
Spooner
v.
McGonnell,
By . the terms tax, impost, and duty, mentioned in the ordinance, is meant a charge for the use of the government, not compensation for improvements. The fact that if any surplus remains from the tolls, over what is used to keep the locks in repair, and for their collection, it is to be paid into the State ‘treasury as a part of the revenue of the 'State, does not change the character of the toll-or impost. In prescribing the rates it would be impossible to state in advance what the tolls would amount to in the aggregate. That- would depend upon the extent'of business done, that is, the number, of vessels and amount of freight which may pass through the locks. Some disposition of the surplus is necessaiy until its use shall be required, and it may as . well be placed in the State treasury, and probably better, than anywhere else.
Nor is there anything in the objection that the rates of toll are prescribed by the commissioners according to the tonnage of the vessels, and the amount of freight carried by them through the locks. This is simply a mode of fixing the rate according to the size of the vessel and the amount of property it carries, and in no sense is a duty of tonnage within the prohibition of the Constitution. A duty of tonnage within the meaning of the Constitution is a charge upon a vessel, according to its tonnage, as' an instrument of commerce, for. enter-, ing or leaving a port, or navigating the public waters of the *550 country; and the prohibition was designed to prevent the, States from imposing hindrances of this kind to commerce carried on by vessels.

It is unnecessary to pursue the subject further. We do not see any objections that would justify a disturbance of the ' decree below, which is accordingly
Affirmed.
