204 U.S. 364

27 S.Ct. 367

51 L.Ed. 523


No. 431.

Argued December 5 and 6, 1906.

Decided February 25, 1907.

This is a proceeding in the nature of a criminal information in the district court of the United States for the western district of Pennsylvania against the Union Bridge Company, a corporation of Pennsylvania, owning and controlling a bridge across the Allegheny river near where it joins the Monongahela river to form the Ohio river,—the Allegheny river being a navigable waterway of the United States, having its source in New York and being navigable in both New York and Pennsylvania.

Stating the matter generally, the Secretary of War found the bridge to be an unreasonable obstruction to the free navigation of the Allegheny river, and required the Bridge Company to make certain changes or alterations in order that navigation be rendered reasonably free, easy, and unobstructed. These alterations, it was charged, the company wilfully failed and refused to make. Hence the present information against it. There was a verdict of guilty, followed by a motion in arrest of judgment, which motion being overruled, the company was sentenced to pay a fine of $5,000. To review that order this writ of error is prosecuted.

The information was based on § 18 of the river and harbor act of March 3d, 1899, which provides: 'That whenever the Secretary of War shall have good reason to believe that any railroad or other bridge now constructed, or which may hereafter be constructed, over any of the navigable water ways of the United States, is an unreasonable obstruction to the free navigation of such waters on account of insufficient height, width of span, or otherwise, or where there is difficulty in passing the draw opening or the draw span of such bridge by rafts, steamboats, or other water craft, it shall be the duty of the said Secretary, first giving the parties reasonable opportunity to be heard, to give notice to the persons or corporations owning or controlling such bridge, so to alter the same as to render navigation through or under it reasonably free, easy, and unobstructed; and in giving such notice he shall specify the changes, recommended by Chief of Engineers, that are required to be made, and shall prescribe in each case a reasonable time in which to make them. If, at the end of such time, the alteration has not been made, the Secretary of War shall forthwith notify the United States district attorney for the district in which such bridge is situated, to the end that the criminal proceedings hereinafter mentioned may be taken. If the persons, corporation, or association owning or controlling any railroad or other bridge shall, after receiving notice to that effect, as hereinbefore required, from the Secretary of War, and within the time prescribed by him, wilfully fail or refuse to remove the same or to comply with the lawful order of the Secretary of War in the premises, such persons, corporation, or association shall be deemed guilty of a misdemeanor, and, on conviction thereof, shall be punished by a fine not exceeding five thousand dollars; and every month such persons, corporation, or association shall remain in default in respect to the removal or alteration of such bridge shall be deemed a new offense, and subject the persons, corporation, or association so offending to the penalties above prescribed: Provided, That in any case arising under the provisions of this section an appeal or writ of error may be taken from the district courts or from the existing circuit courts direct to the Supreme Court, either by the United States or by the defendants.' 30 Stat. at L. 1121, 1153, chap. 425, U. S. Comp. Stat. 1901, p. 3545.

Legislation similar in its general character can be found in river and harbor acts passed at previous sessions of Congress. Act of 1884 (23 Stat. at L. 133, 148, chap. 229, U. S. Comp. Stat. 1901, p. 3532); act of April 11th, 1888 (25 Stat. at L. 400, 424, 425, chap. 860, §§ 9, 10); and act of September 19th, 1890 (26 Stat. at L. 426, 453, chap. 907, §§ 4, 5). Finally, we have the act of March 23d, 1906 (34 Stat. at L. 84, chap. 1130, §§ 4, 5), which covers the same ground as the act of 1899 under which the present information was filed.

It appears that the Bridge Company was incorporated by an act of the Pennsylvania legislature, approved March 13th, 1873, with authority to construct a bridge over the Allegheny river, in the city of Allegheny. That act contains this proviso: 'That the erection of said bridge shall not obstruct the navigation of said river, so as to endanger the passage of rafts, steamboats, or other water crafts; and the piers shall not be so placed as to interfere with towboats proceeding out with their tows made up, and shall be constructed in such manner as to meet the requisitions of the law in regard to the obstructions of navigation.'

The bridge was constructed in 1874 and 1875, and has been in use since 1875.

In 1902 a petition was sent to the Secretary of War by persons, corporations, and companies in and about Pittsburg, which contained, among other things, these statements: 'There can be no doubt whatever that this bridge is an unreasonable obstruction to the free navigation of the Ohio, Monongahela, and Allegheny rivers on account of insufficient height and the filling in of the river or rivers over which it passes in order to provide approaches for it. We respectfully request that you will investigate this matter, having full confidence that, after making such investigation, you will find it to be your duty to take action against its owners, the Union Bridge Company, under the provisions of § 18 of the river and harbor act, approved March 3, A. D. 1899. . . . It was built of such a low height above the water as to cause the almost complete obstruction of all the packet and tow-boat trade passing from the Allegheny river into the Ohio and Monongahela rivers, and from these rivers into the Allegheny. In building it the width of the river was very materially narrowed, as already stated, by the fills made for the approaches. The river commerce of Pittsburg, as you are aware, is of very great magnitude and importance, and is rapidly increasing in volume. For the last calendar year it amounted to 10,916,489 tons, being about equal to that of the harbor of New York. The extension of the manufacturing industries of Pittsburg up the Allegheny river is making it of much greater importance than heretofore that the navigation to and from that river should not be obstructed. The present time is peculiarly appropriate for action by you. The Union bridge is an old, wooden structure, and will soon need—in fact, it already needs—extensive repairs to make it safe for public use. Therefore, as the bridge in question deprives the community of a reasonable use of the Allegheny river in connection with the river business of this great harbor, we appeal to you to exercise the powers committed to you to abate, or to at least mitigate, this great public nuisance, as you shall find yourself justified by the law and the facts of the case.'

The matter was referred by the Secretary of War to the proper officers of the Engineer Corps of the Army for examination and report. Such examination was had upon notice to the Bridge Company, and, under date of December 8th, 1902, Capt. Sibert, cap tain of engineers, who conducted the examination, reported and recommended to the Chief of Engineers that the company be given notice to make certain alterations in its bridge.

On December 16th, 1902, the Chief of Engineers transmitted that report to the Secretary of War, saying: 'As required by the law and the instructions of the War Department, a public hearing has been held, after due advertisement, and all interested parties have been afforded an opportunity to present their views. Attention is respectfully invited to the accompanying report on the subject, dated the 8th instant, by Captain Sibert, and to its accompanying papers. In this report Captain Sibert fully discusses all phases of the question, and shows that, without reference to the use of the Allegheny river for through navigation, the bridge in question is an unreasonable obstruction, and practically a bar to the use of that portion of Pittsburg harbor situated on the river. He states that none of the boats engaged in interstate commerce from Pittsburg, south and west, can reach, at low water, a single manufacuring plant or wharf in the cities of Pittsburg and Allegheny on the Allegheny river. He submits a photograph to show that the portion of Pittsburg harbor in the Monongahela river is crowded with shipping, while that portion in the Allegheny has none, all due to the existence of the Union bridge. It is also shown by the evidence that the lower portion of the Allegheny river would be of great importance as a harbor of refuge when ice is running out of the Monongahela river, if it were not obstructed by the Union bridge. He reaches the conclusion, based on the facts developed at the hearing, that, in order to give the shipping at Pittsburg increased harbor room, and to enable it to connect with wharves and manufacturing plants in that part of the harbor located on the Allegheny river the Union bridge should be so raised as to provide a channel-span with a clear height of 70 feet, the same as exists under the bridge known as the 'Point bridge' on the Monongahela river, and the same that will exist under the Wabash Railroad bridge just being built, immediately above the Point bridge. It appears that this bridge was built in 1873, 1874 by the Union Bridge Company, incorporated under authority of an act of the Pennsylvania legislature of March 13, 1873, and that it has been the subject of complaint on the part of the navigation interests practically ever since its completion. Numerous investigations have been made by different engineer officers, who have held public hearings on the bubject, and who have concurred in expressing the opinion that the bridge was an unreasonable obstruction to navigation, and that it should be raised so as to give a headroom equal, at least, to that of the aforesaid Point bridge at the mouth of the Monongahela river. The Union bridge is situated at the mouth of the Allegheny river, and there seems to be no room for doubt that the alteration of the bridge is essential to the reasonable use for navigation and commercial purposes of that portion of the river forming a part of Pittsburg harbor. Captain Sibert recommends that the bridge in question be so altered as to give two navigable spans extending riverwards from the left abutment, of not less than 394 feet clear width each; the second span from the Pittsburg shore to give a clear headroom over the Davis Island pool of not less than 70 feet; and the first span from the same shore to give a headroom of not less than 70 feet at the pier and 62 feet at the abutment; also that the piers of the altered structure shall have no riprapping or other pier protection above an elevation of 10 feet below the surface of Davis Island pool, and that all parts of the old structure not comprised in the new construction, and in conformity with the above requirements, shall be wholly removed. The period of eighteen months is considered by him ample time within which to make these alterations. I concur in his views and recommend that notice be served on the Bridge Company, requiring the alterations to be made and completed as specified by him.'

Under date of 20th of January, 1903, Mr. Root, then Secretary of War, issued a formal notice to the Bridge Company, stating that he had good reason to believe that its bridge was an unreasonable obstruction to free navigation. The notice informed the company of the alterations of its bridge recommended by the Chief of Engineers as necessary, and concluded: 'And whereas, eighteen months from the date of service of this notice is a reasonable time in which to alter the said bridge as described above; Now, therefore, in obedience to, and by virtue of, § 18 of an act of the Congress of the United States entitled 'An Act Making Appropriations for the Construction, Repair, and Preservation of Certain Public Works on Rivers and Harbors, and for Other Purposes,' approved March 3, 1899, I, Elihu Root, Secretary of War, do hereby notify the said Union Bridge Company to alter the said bridge as described above, and prescribe that said alterations shall be made and completed on or before the expiration of eighteen months from the date of service hereof.'

At the request of the Bridge Company, the time fixed by Secretary Root for altering, changing, and elevating the bridge was extended by his successor, Secretary Taft, to December 1st, 1904. By order of the latter officer the time was extended to January 1st, 1905.

Subsequently, a rehearing was asked for by the Bridge Company, but the rehearing was refused and Secretary Taft made the following order: 'The Union bridge is an unreasonable obstruction to commerce of the Allegheny river. If the bridge were not there, the winter refuge which the stretch of the Allegheny river up to the next bridge would offer for the fleet of boats which usually are moored in the Monongahela would be a very great advantage for navigation and commerce on the Ohio river and its tributaries. The two rivers, the Allegheny and the Monongahela, because they rise in different sections of the country, have their ice breaks at different times in the early spring. The mouth of the one offers very desirable refuge to the vessels that are exposed to danger from the breaking up of ice in the headwaters of the other. The Union bridge, at the mouth of the Allegheny, was erected at a time when the Secretary of War was not given specific control over navigable streams, and was not authorized to inhibit the construction of bridges which were likely to obstruct navigation; but it appears that an army engineer, Colonel Merrill, in charge of the district, publicly announced that this bridge was an obstruction to navigation when it was erected. It was erected, therefore, in the face of the information given by the best authority that could be consulted in that matter in the government. These are the facts that I find independently of any previous adjudication; but, added to this is the finding of my predecessor, Mr. Root, to exactly the same effect, upon which he based an order that the bridge, as an obstruction to navigation, be abated. This matter is now before me on a petition for rehearing of Mr. Root's order. As an original question I should have ruled as Mr. Root ruled, and a fortiori because the orders of this Department are not to be lightly set aside, and are to be treated as a decree in equity would be, and be set aside only upon a showing of a palpable error or mistake. The petition for rehearing is denied, and the order suspending the operation of Mr. Root's order is now revoked. The order will be put in full force and executed by the proper officers, and the Union Bridge will be notified accordingly.'

In the opinion of the district court, delivered on a motion in arrest of judgment, it was said: 'The obstruction here involved consists of a bridge over the Allegheny river just above its junction with the Monongahela at Pittsburgh. The Allegheny river rises in Pennsylvania, flows north into New York state, and thence back into Pennsylvania. The latter state, by act of March 21, 1798 (3 Smith's Laws, p. 320), enacted the Allegheny, from the New York state line to its mouth, a navigable stream, and the state of New York, by act of March 31, 1807, did likewise in its counties of Genesee and Allegheny. The Allegheny is the principal branch of the Ohio, its volume being six times greater than that of the Monongahela. It is included in the general plan for the improvement by the national government of local interstate waterways and the harbor of Pittsburg. The government has built, or has now in process of construction, a system of locks and dams on the Allegheny which will slackwater the stream for 27 miles from its mouth. The Davis Island dam, situate 5 miles below Pittsburg, on the Ohio river, raises the water in the Allegheny and Monongahela at their junction 6 feet above their normal depths, and backs its water to the first dams of the Allegheny and Monongahela slackwater systems respectively. These waters form the harhor of Pittsburg, the importance of which harbor will be appreciated from the fact that the tonnage in water transportation passing from it the past year exceeded that of the Suez canal for the same period. From its size, interstate relation, and its being a part of this really great harbor, it will be seen that the Allegheny answers the requirement of a navigable stream (The Montello [United States v. The Montello], 11 Wall. 411, 20 L. ed. 191), and is also one over which the national government has assumed jurisdiction. The Union bridge is a pier-supported, wooden structure; it crosses from Pittsburg to Allegheny City; and is the first bridge on the Allegheny.' [143 Fed. 378.]

Assistant to the Attorney General Purdy for defendant in error.

Mr. Justice Harlan delivered the opinion of the court:


The first principal question raised by the defendant is whether the 18th section of the river and harbor act of March 3d, 1899, is in violation of the Constitution of the United States as delegating legislative and judicial powers to the head of an executive department of the government. This question, the government contends, has been determined in its favor by the principles heretofore announced by this court, and need not be discussed as if now presented for the first time. In its judicial as well as legal aspects the question is of such importance as to justify a full reference to prior decisions.


The earliest case is that of The Aurora v. United States, 7 Cranch, 382, 3 L. ed. 378, which involved the question whether Congress could make the revival of a law (which had ceased to be in force) depend upon the existence of certain facts, to be ascertained by the President and set forth in a proclamation by him. The court said: 'We can see no sufficient reason why the legislature should not exercise its discretion in reviving the act of March 1st, 1809 [2 Stat. at L. 528, chap. 24], either expressly or conditionally, as their judgment should direct. The 19th section of that act, declaring that it should continue in force to a certain time, and no longer, could not restrict their power of extending its operation without limitation upon the occurrence of any subsequent combination of events.' Referring to this language, we said in the subsequent case of Marshall Field & Co. v. Clark, 143 U. S. 649, 683, 36 L. ed. 294, 307, 12 Sup. Ct. Rep. 495, 501: 'This certainly is a decision that it was competent for Congress to make the revival of an act depend upon the proclamation of the President, showing the ascertainment by him of the fact that the edicts of certain nations had been so revoked or modimodified that they did not violate the neutral commerce of the United States. The same principle would apply in the case of the suspension of an act upon a contingency to be ascertained by the President and made known by his proclamation.'


In Wayman v. Southard, 10 Wheat. 1, 43, 45, 46, 6 L. ed. 253, 262, 263, Chief Justice Marshall, delivering the unanimous judgment of the court, said that although Congress could not delegate to the courts or to any other tribunals powers strictly and exclusively legislative, and although the line had not been exactly drawn that separates the important subjects which must be entirely regulated by the legislature itself from those of less interest 'in which a general provision may be made, and powers given to those who are to act under such general provisions to fill up the details,' yet 'Congress may certainly delegate to others powers which the legislature may rightly exercise itself,' and 'the maker of the law may commit something to the discretion of the other departments.'


In Marshall Field & Co. v. Clark, just cited, 143 U. S. 649, 680, 683, 691, 692, 36 L. ed. 294, 306, 307, 309, 310, 12 Sup. Ct. Rep. 495, 500, 501, 504, 505, the question arose as to the constitutionality of that section of the McKinley tariff act of 1890 [26 Stat. at L. 612, chap. 1244, § 3] which provided for the imposition, in a named contingency (to be determined by the President and manifested by his proclamation), of duties upon sugar, molasses, and other specified articles, which the act had placed in the free list. By that section it was declared that 'with a view to secure reciprocal trade with countries producing the following articles and for this purpose, on and after the first day of January, eighteen hundred and ninety-two, whenever, and so often as the President shall be satisfied that the government of any country producing and exporting sugars, molasses, coffee, tea, and hides, raw and uncured, or any of such articles, imposes duties or other exactions upon the agricultural or other products of the United States, which, in view of the free introduction of such sugar, molasses, coffee, tea, and hides into the United States, he may deem to be reciprocally unequal and unreasonable, he shall have the power, and it shall be his duty, to suspend, by proclamation to that effect, the provisions of this act relating to the free introduction of such sugar, molasses, coffee, tea, and hides, the production of such country, for such time as he shall deem just, and in such case and during such suspension duties shall be levied, collected, and paid upon sugar, molasses, coffee, tea, and hides, the product of or exported from such designated country, as follows, namely.' Here follows in the act provisions indicating the particular duties to be collected, after the President's proclamation upon sugars, molasses, coffee, tea, hides, etc. It was contended in the Field Case that the above section, so far as it authorized the President to suspend by proclamation the provisions of the act relating to the free introduction of sugar, molasses, coffee, etc., was unconstitutional, as delegating to him both legislative and treaty-making powers. In its consideration of this question the court, after referring to the case of The Aurora, above cited, examined the numerous precedents in legislation showing to what extent the suspension of certain provisions and the going into operation of other provisions of an act of Congress had been made to depend entirely upon the finding or ascertainment by the President of certain facts, to be made known by his Proclamation. The acts of Congress which underwent examination by the court are noted in the margin. The result of that examination of legislative precedents was thus stated: 'The authority given to the President by the act of June 4, 1794 [1 Stat. at L. 372, chap. 41], to lay an embargo on all ships and vessels in the ports of the United States, 'whenever, in his opinion, the public safety shall so require,' and under regulations, to be continued or revoked, 'whenever he shall think proper;' by the act of February 9, 1799, to remit and discontinue, for the time being, the restraints and prohibitions which Congress had prescribed with respect to commercial intercourse with the French Republic, 'if he shall deem it expedient and consistent with the interest of the United States,' and 'to revoke such order whenever, in his opinion, the interest of the United States shall require;' by the act of December 19, 1806, to suspend, for a named time, the operation of the nonimportation act of the same year, 'if, in his judgment, the public interest should require it;' by the act of May 1, 1810 [2 Stat. at L. 606, chap. 39, § 4], to revive a former act, as to Great Britain or France, if either country had not, by a named day, so revoked or modified its edicts as not 'to violate the neutral commerce of the United States;' by the acts of March 3, 1815, and May 31, 1830, to declare the repeal, as to any foreign nation, of the several acts imposing duties on the tonnage of ships and vessels, and on goods, wares, and merchandise imported into the United States, when he should be 'satisfied' that the discriminating duties of such foreign nations, 'so far as they operate to the disadvantage of the United States,' had been abolished; by the act of March 6, 1866, to declare the provisions of the act forbidding the importation into this country of neat cattle and the hides of neat cattle, to be inoperative, 'whenever, in his judgment,' their importation 'may be made without danger of the introduction of spread of contagious or infectious disease among the cattle of the United States,'—must be regarded as unwarranted by the Constitution, if the contention of the appellants in respect to the 3d section of the act of October 1, 1890, be sustained.'


Touching the general question the court said: 'That Congress cannot delegate legislative power to the President is a principle universally recognized as vital to the integrity and maintenance of the system of government ordained by the Constitution. The act of October 1, 1890, in the particular under consideration, is not inconsistent with that principle. It does not, in any real sense, invest the President with the power of legislation. For the purpose of securing reciprocal trade with countries producing and exporting sugar, molasses, coffee, tea, and hides, Congress itself determined that the provisions of the act of October 1, 1890, permitting the free introduction of such articles, should be suspended as to any country producing and exporting them that imposed exactions and duties on the agricultural and other products of the United States, which the President deemed, that is, which he found to be, reciprocally unequal and unreasonable. Congress itself prescribed, in advance, the duties to be levied, collected, and paid, on sugar, molasses, coffee, tea, or hides, produced by or exported from such designated country, while the suspension lasted. Nothing involving the expediency or the just operation of such legislation was left to the determination of the President. The words, 'he may deem,' in the 3d section, of course, implied that the President would examine the commercial regulations of other countries producing and exporting sugar, molasses, coffee, tea, and hides, and form a judgment as to whether they were reciprocally equal and reasonable, or the contrary, in their effect upon American products. But when he ascertained the fact that duties and exactions, reciprocally unequal and unreasonable, were imposed upon the agricultural or other products of the United States by a country producing and exporting sugar, molasses, coffee, tea, or hides, it became his duty to issue a proclamation declaring the suspension, as to that country, which Congress had determined should occur. He had no discretion in the premises except in respect to the duration of the suspension so ordered. But that related only to the enforcement of the policy established by Congress. As the suspension was absolutely required when the President ascertained the existence of a particular fact, it cannot be said that, it ascertaining that fact, and in issuing his proclamation, in obedience to the legislative will, he exercised the function of making laws. Legislative power was exercised when Congress declared that the suspension should take effect upon a named contingency. What the President was required to do was simply in execution of the act of Congress. It was not the making of law. He was the mere agent of the lawmaking department to ascertain and declare the event upon which its expressed will was to take effect. It was a part of the law itself as it left the hands of Congress that the provisions, full and complete in themselves, permitting the free introduction of sugars, molasses, coffee, tea, and hides, from particular countries, should be suspended, in a given contingency, and that, in case of such suspensions, certain duties should be imposed.' Again: "The true distinction,' as Judge Ranney, speaking for the supreme court of Ohio, has well said, 'is between the delegation of power to make the law, which necessarily involves a discretion as to what it shall be, and conferring authority or discretion as to its execution, to be exercised under and in pursuance of the law. The first cannot be done; to the latter no valid objection can be made.' Cincinnati, W. & Z. R. Co. v. Clinton County, 1 Ohio St. 88. In Moers v. Reading, 21 Pa. 188, 202, the language of the court was: 'Half the statutes on our books are in the alternative, depending on the discretion of some person or persons to whom is confided the duty of determining whether the proper occasion exists for executing them. But it cannot be said that the exercise of such discretion is the making of the law.' So, in Locke's Appeal, 72 Pa. 491, 498, 13 Am. Rep. 716, 721: 'To assert that a law is less than a law because it is made to depend on a furture event or act is to rob the legislature of the power to act wisely for the public welfare whenever a law is passed relating to a state of affairs not yet developed, or to things future and impossible to fully know.' The proper distinction, the court said, was this: 'The legislature cannot delegate its power to make a law; but it can make a law to delegate a power to determine some fact or state of things upon which the law makes, or intends to make, its own action depend. To deny this would be to stop the wheels of government. There are many things upon which wise and useful legislation must depend which cannot be known to the lawmaking power, and must, therefore, be a subject of inquiry and determination outside of the halls of legislation.' What has been said is equally applicable to the objection that the 3d section of the act invests the President with treatymaking power. The court is of the opinion that the 3d section of the act of October 1, 1890, is not liable to the objection that it transfers legislative and treaty-making power to the President.'


The latest case bearing on the general question is Buttfield v. Stranahan, 192 U. S. 470, 496, 48 L. ed. 525, 535, 24 Sup. Ct. Rep. 349, 355. That case involved the constitutionality of the act of Congress of March 2d, 1897 (29 Stat. at L. 604, chap. 358, U. S. Comp. Stat. 1901, p. 3194), relating to the 'importation of impure and unwholesome tea.' The act provided for the appointment by the Secretary of the Treasury of a board of seven tea experts, who should prepare and submit to him standard samples of that article. One section of the act provided: 'That the Secretary of the Treasury, upon the recommendation of the said board, shall fix and establish uniform standards of purity, quality, and fitness for consumption of all kinds of teas imported into the United States, and shall procure and deposit in the custom houses of the ports of New York, Chicago, San Francisco, and such other ports as he may determine, duplicate samples of such standards; that said Secretary shall procure a sufficient number of other duplicate samples of such standards to supply the importers and dealers in tea at all ports desiring the same at cost. All teas, or merchandise described as tea, of inferior purity, quality, and fitness for consumption to such standards shall be deemed within the prohibition of the 1st section hereof.' [§ 3.] In that case it was contended that the act was unconstitutional, as making the right to import tea depend upon the arbitrary action of the Secretary of the Treasury and a board appointed by him; as excluding from import wholesome, genuine and unadulterated tea; and, as discriminating unequally in the admission of the different kinds of teas for import, as well as in the right to sell and purchase that article. The act conferred, it was objected, upon the Secretary and the board, the uncontrolled power of fixing standards of purity, quality, and fitness for consumption, and thus to prescribe arbitrarily what teas may be imported and dealt in. The question of constitutional law so raised was thus disposed of by the court: 'The claim that the statute commits to the arbitrary discretion of the Secretary of the Treasury the determination of what teas may be imported, and therefore in effect vests that official with legislative power, is without merit. We are of opinion that the statute, when properly construed, as said by the circuit court of appeals, but express the purpose to exclude the lowest grades of tea, whether demonstrably of inferior purity, or unfit for consumption, or presumably so because of their inferior quality. This, in effect, was the fixing of a primary standard, and devolved upon the Secretary of the Treasury the mere executive duty to effectuate the legislative policy declared in the statute. The case is within the principle of Marshall Field & Co. v. Clark, 143 U. S. 649, 36 L. ed. 294, 12 Sup. Ct. Rep. 495, where it was decided that the 3d section of the tariff act of October 1, 1890, was not repugnant to the Constitution as conferring legislative and treaty-making power on the President, because it authorized him to suspend the provisions of the act relating to the free introduction of sugar, molasses, coffee, tea, and hides. We may say of the legislation in this case, as was said of the legislation considered in Marshall Field & Co. v. Clark, that it does not, in any real sense, invest administrative officials with the power of legislation. Congress legislated on the subject as far as was reasonably practicable, and, from the necessities of the case, was compelled to leave to executive officials the duty of bringing about the result pointed out by the statute. To deny the power of Congress to delegate such a duty would, in effect, amount but to declaring that the plenary power vested in Congress to regulate foreign commerce could not be efficaciously exerted.'


It would seem too clear to admit of serious doubt that the statute under which the Secretary of War proceeded is in entire harmony with the principles announced in former cases. In no substantial, just sense does it confer upon that officer, as the head of an executive department, powers strictly legislative or judicial in their nature, or which must be exclusively exercised by Congress or by the courts. it has long been the policy of the government to remove such unreasonable obstructions to the free navigation of the water ways of the United States as were caused by bridges maintained over them. That such an object was of common interest and within the competency of Congress, under its power to regulate commerce, everyone must admit: for commerce comprehends navigation, and therefore to free navigation from unreasonable obstructions is a legitimate exertion of that power. Gibbons v. Odgen, 9 Wheat. 1, 189, 190, 6 L. ed. 23, 68, 69. As appropriate to the object to be accomplished, as a means to an end within the power of the national government, Congress, in execution of a declared policy, committed to the Secretary of War the duty of ascertaining all the facts essential in any inquiry whether particular bridges, over the water ways of the United States, were unreasonable obstructions to free navigation. Beyond question, if it had so elected, Congress, in some effective mode and without previous investigation through executive officers, could have determined for itself, primarily, the fact whether the bridge here in question was an unreasonable obstruction to navigation, and, if it was found to be of that character could, by direct legislation, have required the defendant to make such alterations of its bridge as were requisite for the protection of navigation and commerce over the water way in question. But investigations by Congress as to each particular bridge alleged to constitute an unreasonable obstruction to free navigation, and direct legislation covering each case, separately, would be impracticable, in view of the vast and varied interests which require national legislation from time to time. By the statute in question Congress declared in effect that navigation should be freed from unreasonable obstructions arising from bridges of insufficient height, width of span, or other defects. It stopped, however, with this declaration of a general rule, and imposed upon the Secretary of War the duty of ascertaining what particular cases came within the rule prescribed by Congress, as well as the duty of enforcing the rule in such cases. In performing that duty the Secretary of War will only execute the clearly-expressed will of Congress, and will not, in any true sense, exert legislative or judicial power. He could not be said to exercise strictly legislative or judicial power any more, for instance, than it could be said that executive officers exercise such power when, upon investigation, they ascertain whether a particular applicant for a pension belongs to a class of persons who, under the general rules prescribed by Congress, are entitled to pensions. If the principle for which the defendant contends received our approval the conclusion could not be avoided that executive officers, in all the departments, in carrying out the will of Congress, as expressed in statutes enacted by it, have, from the foundation of the national government, exercised, and are now exercising, powers as to mere details, that are strictly legislative or judicial in their nature. This will be apparent upon an examination of the various statutes that confer aothority upon executive departments in respect of the enforcement of the laws of the United States. Indeed, it is not too much to say that a denial to Congress of the right, under the Constitution, to delegate the power to determine some fact or the state of things upon which the enforcement of its enactment depends, would be 'to stop the wheels of government' and bring about confusion, if not paralysis, in the conduct of the public business.


To this may be added the consideration that Congress, by the act of 1899, did not invest the Secretary of War with any power in these matters that could reasonably be characterized as arbitrary. He cannot act in reference to any bridge alleged to be an unreasonable obstruction to free navigation without first giving the parties an opportunity to be heard. He cannot require any bridge of that character to be altered, even for the purpose of rendering navigation through or under it reasonably free, easy, and unobstructed, without giving previous notice to the persons or corporations owning or controlling the bridge, specifying the changes recommended by the Chief of Engineers, and allowing a reasonable time in which to make them. If, at the end of such time, the required alterations have not been made, then the Secretary is required to bring the matter to the attention of the United States district attorney in order that criminal proceedings may be instituted to enforce the act of Congress. In the present case all the provisions of the statute were complied with. The parties concerned were duly notified and were fully heard. Nor is there any reason to say that the Secretary of War was not entirely justified, if not compelled, by the evidence, in finding that the bridge in question was an unreasonable obstruction to commerce and navigation as now conducted.


We are of opinion that the act in question is not unconstitutional as conferring upon the Secretary of War powers of such nature that they could not be delegated to him by Congress.


The next principal contention of the Bridge Company is that the act of 1899 is unconstitutional, in that it makes no provision, and the United States has not offered, to compensate if for the sum that will necessarily be expended in order to make the alterations or changes required by the order of the Secretary of War. In other words, the defendant insists that what the United States requires to be done in respect of defendant's bridge a taking of private property for public use, which the government is fordidden by the Constitution to do without making just compensation to, or without making provision to justly compensate, the owner. Stating the question in another way, the contention is, in effect, that even if the United States did not expressly assent to the construction of this bridge as it is, and even if the bridge has become an unreasonable obstruction to the free navigation of the water way in question, the exertion of the power of the United States to regulate commerce among the states is subject to fundamental condition that it cannot require the defendant, whose bridge was lawfully constructed, to make any alterations, however necessary to secure free navigation, without paying or securing to it compensation for the reasonable cost of such alterations.


The propositions are combated by the government, which contends that the alterations or changes required to secure navigation against an unreasonable obstruction is not a taking of private property for public use within the meaning of the Constitution, and that the cost of such alterations or changes is to be deemed incidental only to the exercise of an undoubted function of the United States, when exerting, through Congress, its power to regulate commerce among the states, and therefore navigation upon the water ways on and over which such commerce is conducted.


It would seem clear that this issue has likewise been determined by the principles announced in the previous cases of this court. Let us see whether such be the fact.


A leading case upon this subject is Gibson v. United States, 166 U. S. 269, 271, 41 L. ed. 996, 998, 17 Sup. Ct. Rep. 578, 579, et seq. Congress, by the river and harbor acts of 1884 and 1886 (23 Stat. at L. 133, 147, chap. 229, U. S. Comp. Stat. 1901, p. 3524, 24 Stat. at L. 316, 327, chap. 929), authorized and directed the improvement of the Ohio river, and made appropriations to effect that object. Under the authority of the Secretary of War, and the Engineer Corps of the Army, a dike was constructed in that river for the purpose of concentrating the water-flow in the main channel of the river, near Neville island. The dike began at a certain point on the island. Its construction substantially destroyed the landing on and in front of a farm, owned by Mrs. Gibson, on that island, preventing, during most of the year, free egress and ingress from and to such farm to the main or navigable channel of the river. At the time of the construction of the dike that farm was in high state of cultivation, well improved, with a dwelling house, barn, and outbuildings. It had a frontage of a thousand feet on the main navigable channel, and the owner had a landing there which was used in the shipping of products from and supplies to her farm, and was the only one from which such products and supplies could be shipped. Before the construction of the dike the farm, by reason of the use to which it was put, was worth $600 per acre. The obstruction caused by the dike reduced its value to $150 or $200 per acre, resulting in damages to the owner in excess of $3,000. Suit was brought against the United States in the court of claims to recover such damages. That court found, as a conclusion of law, that the owner was not entitled to recover.


The Chief Justice of this court, delivering its unanimous judgment, said: 'All navigable waters are under the control of the United States for the purpose of regulating and improving navigation, and although the title to the shore and submerged soil is in the various states and individual owners under them, it is always subject to the servitude in respect of navigation created in favor of the Federal government by the Constitution. South Carolina v. Georgia, 93 U. S. 4, 23 L. ed. 782; Shively v. Bowlby, 152 U. S. 1, 38 L. ed. 331, 14 Sup. Ct. Rep. 548; Eldridge v. Trezevant, 160 U. S. 452, 40 L. ed. 490, 16 Sup. Ct. Rep. 345.' After referring to several adjudged cases the court proceeded: 'The 5th Amendment to the Constitution of the United States provides that private property shall not 'be taken for public use without just compensation.' Here, however, the damage of which Mrs. Gibson complained was not the result of the taking of any part of her property, whether upland or submerged, or a direct invasion thereof, but the incidental consequence of the lawful and proper exercise of a governmental power. The applicable principle is expounded in Northern Transp. Co. v. Chicago, 99 U. S. 635, 25 L. ed. 336. In that case, plaintiff, being an owner of land situated at the intersection of La Salle street in Chicago, with the Chicago river, upon which it had valuable dock and warehouse accommodations, with a numerous line of steamers accustomed to land at that dock, was interrupted in his use thereof by the building of a tunnel under the Chicago river by authority of the state legislature, in accomplishing which work it was necessary to tear up La Salle street, which precluded plaintiff from access to his property for a considerable time; also to build a coffer dam in the Chicago river, which excluded his vessels from access to his docks; and such an injury was held to be damnum absque injuria. The court said, again speaking through Mr. Justice Strong: 'But acts done in the proper exercise of governmental powers, and not directly encroaching upon private property, though their consequences may impair its use, are universally held not to be a taking within the meaning of the constitutional provision. They do not entitle the owner of such property to compensation from the state or its agents, or give him any right of action. This is supported by an immense weight of authority.' . . . Moreover, riparian ownership is subject to the obligation to suffer the consequences of the improvement of navigation in the exercise of the dominant right of the government in that regard. The legislative authority for these works consisted simply in an appropriation for their construction, but this was an assertion of a right belonging to the government, to which riparian property was subject, and not of a right to appropriate private property, not burdened with such servitude, to public purposes. In short, the damage resulting from the prosecution of this improvement of a navigable highway for the public good was not the result of a taking of appellant's property, and was merely incidental to the exercise of a servitude to which her property had always been subject.'


The Gibson Case was referred to with approval in Scranton v. Wheeler, 179 U. S. 141, 153, 162, 45 L. ed. 126, 133, 137, 21 Sup. Ct. Rep. 48, 53, 57. The latter case involved the question whether the owner of land on the St. Mary's river, in Michigan, was entitled, under the Constitution of the United States, to be compensated for the injury or damage done him, as a riparian owner, by certain work done in that river under the authority of the United States. The controlling question was whether the prohibition in the Constitution of the United States of the taking of private property for public use without just compensation has any application to the case of an owner of land bordering on a public navigable river whose access from his land to navigability is permanently lost by reason of the construction of a pier resting on submerged lands in front of his upland, and which pier was erected by the United States for the purpose only of improving the navigation of such river. After observing that when that which is done amounts, within the meaning of the Constitution, to a taking of private property for public use, and that Congress may not, in the exercise of its power to regulate commerce, override the provision for just compensation when private property is so taken, the court entered upon a review of some of the adjudged cases. Among other things it said: 'All the cases concur in holding that the power of Congress to regulate commerce, and therefore navigation, is paramount, and is unrestricted except by the limitations upon its authority by the Constitution. Of course, every part of the Constitution is as binding upon Congress as upon the people. The guaranties prescribed by it for the security of private property must be respected by all. But whether navigation upon waters over which Congress may exert its authority requires improvement at all, or improvement in a particular way, are matters wholly within its discretion; and the judiciary is without power to control or defeat the will of Congress, so long as that branch of the government does not transcend the limits established by the supreme law of the land. Is the broad power with which Congress is invested burdened with the condition that a riparian owner whose land borders upon a navigable water of the United States shall be compensated for his right of access to navigability whenever such right ceases to be of value solely in consequence of the improvement of navigation by means of piers resting upon submerged lands away from the shore line? We think not.' 'The primary use,' the court said, 'of the waters and the lands under them is for purposes of navigation, and the erection of piers in them to improve navigation for the public is entirely consistent with such use, and infringes no right of the riparian owner. Whatever the nature of the interest of a riparian owner in the submerged lands in front of his upland bordering on a public navigable water, his title is not as full and complete as his title to fast land which has no direct connection with the navigation of such water. It is a qualified title, a bare technical title, not at his absolute disposal, as is his upland, but to be held at all times subordinate to such use of the submerged lands and of the waters flowing over them as may be consistent with or demanded by the public right of navigation. In Lorman v. Benson, 8 Mich. 18, 22, 77 Am. Dec. 435, the supreme court of Michigan, speaking by Justice Campbell, declared the right of navigation to be one to which all others were subservient. . . . But the contention is that compensation must be made for the loss of the plaintiff's access from his upland to navigability incidentally resulting from the occupancy of the submerged lands, even if the construction and maintenance of a pier resting upon them be necessary or valuable in the proper improvement of navigation. We cannot assent to this view. If the riparian owner cannot enjoy access to navigability because of the improvement of navigation by the construction away from the shore line of works in a public navigable river or water, and if such right of access ceases alone for that reason to be of value, there is not, within the meaning of the Constitution, a taking of private property for public use, but only a consequential injury to a right which must be enjoyed, as was said in Yates v. Milwaukee, 10 Wall. 497, 504, 505, 19 L. ed. 984, 986, 987, 'in due subjection to the rights of the public,'—an injury resulting incidentally from the exercise of a governmental power for the benefit of the general public, and from which no duty arises to make or secure compensation to the riparian owner. The riparian owner acquired the right of access to navigability subject to the contingency that such right might become valueless in consequence of the erection under competent authority of structures on the submerged lands in front of his property for the purpose of improving navigation. When erecting the pier in question, the government had no object in view except, in the interest of the public, to improve navigation. It was not designed arbitrarily or capriciously to destroy rights belonging to any riparian owner. What was done was manifestly necessary to meet the demands of international and interstate commerce.' The court further said: 'In our opinion, it was not intended that the paramount authority of Congress to improve the navigation of the public navigable waters of the United States should be crippled by compelling the government to make compensation for the injury to a riparian owner's right of access to navigability that might incidentally result from an improvement ordered by Congress. The subject with which Congress dealt was navigation. That which was sought to be accomplished was simply to improve navigation on the waters in question so as to meet the wants of the vast commerce passing and to pass over them. Consequently the agents designated to perform the work ordered or authorized by Congress had the right to proceed in all proper ways without taking into account the injury that might possibly or indirectly result from such work to the right of access by riparian owners to navigability. . . . . We are of opinion that the court below correctly held that the plaintiff had no such right of property in the submerged lands on which the pier in question rests as entitles him, under the Constitution, to be compensated for any loss of access from his upland to navigability resulting from the erection and maintenance of such pier by the United States in order to improve, and which manifestly did improve, the navigation of a public navigable water.'


In New Orleans Gaslight Co. v. Drainage Commission, 197 U. S. 453, 461, 462, 49 L. ed. 831, 835, 25 Sup. Ct. Rep. 471, 473, 474, it appeared that, under contract with the city of New Orleans, and at its own expense, the gaslight company had lawfully laid its pipes at certain places in the public ways and streets of that city. Subsequently, the drainage commission of New Orleans adopted a plan for the drainage of the city, which made it necessary to change the location in some places of the mains and pipes theretofore laid by the gaslight company. That company contended that to require such changes was a taking of its property for public use, for which it was entitled, under the Constitution, to compensation. That view was rejected by this court. We said: 'The gas company did not acquire any specific location in the streets; it was content with the general right to use them, and when it located its pipes it was at the risk that they might be, at some future time, disturbed, when the state might require, for a necessary public use, that changes in location be made. . . . The need of occupation of the soil beneath the streets in cities is constantly increasing, for the supply of water and light and the construction of systems of sewerage and drainage, and every reason of public policy requires that grants of rights in such subsurface shall be held subject to such reasonable regulation as the public health and safety may require. There is nothing in the grant to the gas company, even if it could legally be done, undertaking to limit the right of the state to establish a system of drainage in the streets. We think whatever right the gas company acquired was subject, in so far as the location of its pipes was concerned, to such future regulations as might be required in the interest of the public health and welfare. These views are amply sustained by the authorities. National Waterworks Co. v. Kansas City, 28 Fed. 921, in which the opinion was delivered by Mr. Justice Brewer, then circuit judge; Columbus Gaslight & Coke Co. v. Columbus, 50 Ohio St. 65, 19 L.R.A. 510, 40 Am. St. Rep. 648, 33 N. E. 292; Jamaica Pond Aqueduct Corp. v. Brookline, 121 Mass. 5; Re Deering, 93 N. Y. 361; Chicago, B. & Q. R. Co. v. Chicago, 166 U. S. 226, 254, 41 L. ed. 979, 990, 17 Sup. Ct. Rep. 581. In the latter case it was held that uncompensated obedience to a regulation enacted for the public safety under the police power of the state was not taking property without due compensation. In our view, that is all there is to this case. The gas company, by its grant from the city, acquired no exclusive right to the location of its pipes in the streets, as chosen by it, under a general grant of authority to use the streets. The city made no contract that the gas company should not be disturbed in the location chosen. In the exercise of the police power of the state, for a purpose highly necessary in the promotion of the public health, it has become necessary to change the location of the pipes of the gas company so as to accommodate them to the new public work. In complying with this requirement at its own expense none of the property of the gas company has been taken, and the injury sustained is damnum absque injuria.'


In Chicago, B. & Q. R. Co. v. Illinois, 200 U. S. 561, 582, 593-595, 50 L. ed. 596, 605, 609, 610, 26 Sup. Ct. Rep. 341, 345, 350, 351, the above cases were cited with approval, and the principles announced in them were applied against a railway company owning a bridge that had been lawfully constructed by it over a non-navigable creek running through certain swamp or slough lands which the drainage commissioners were required by statute to drain in order to make them tillable and fit for cultivation. The commissioners, in executing the work of draining, found it necessary that the creek over which the railway bridge was constructed should be deepened and enlarged, and a greater opening made under the bridge for the passage of the increased amount of water caused by the deepening and enlarging of the bed of the creek. The railway company was required, at its own cost, to construct such a bridge over the creek as would meet the necessities of the situation as it was or would be under the drainage plan of the commissioners. The company refused to obey the order. The contention of the railway company was that, as the bridge was lawfully constructed under its general corporate powers, and as the depth and width of the channel under it was sufficient, at the time, to carry off the water of the creek as it then and subsequently flowed, the foundation of the bridge could not be removed and its use of the bridge disturbed, unless compensation be first made or secured to the company in such amount as would be sufficient to meet the expense of removing the timbers and stones from the creek and of constructing a new bridge of such length and with such opening under it as the plan of the commissioners would make necessary. The company insisted that to require it to meet these expenses out of its own funds would be, within the meaning of the Constitution, a taking of its property for public use without compensation, and, therefore, without due process of law. The court, after a review of authorities, said: 'The constitutional requirement of due process of law, which embraces compensation for private property taken for public use, applies in every case of the exertion of governmental power. If, in the execution of any power, no matter what it is, the government, Federal or state, finds it necessary to take private property for public use, it must obey the constitutional injunction to make or secure just compensation to the owner. Cherokee Nation v. Southern Kansas R. Co. 135 U. S. 641, 659, 34 L. ed. 295, 303, 10 Sup. Ct. Rep. 965; Sweet v. Rechel, 159 U. S. 380, 399, 402, 40 L. ed. 188, 196, 197, 16 Sup. Ct. Rep. 43; Monongahela Nav. Co. v. United States, 148 U. S. 312, 336, 37 L. ed. 463, 471, 13 Sup. Ct. Rep. 622; United States v. Lynah, 188 U. S. 445, 47 L. ed. 539, 23 Sup. Ct. Rep. 349. If the means employed have no real substantial relation to public objects which government may legally accomplish,—if they are arbitrary and unreasonable, beyond the necessities of the case,—the judiciary will disregard mere forms, and interfere for the protection of rights injuriously affected by such illegal action. The authority of the courts to interfere in such cases is beyond all doubt. Minnesota v. Barber, 136 U. S. 313, 320, 34 L. ed. 455, 458, 3 Inters. Com. Rep. 185, 10 Sup. Ct. Rep. 862, Upon the general subject there is no real conflict among the adjudged cases. Whatever conflict there is arises upon the question whether there has been or will be, in the particular case, within the true meaning of the Constitution, a 'taking' of private property for public use. If the injury complained of is only incidental to the legitimate exercise of governmental powers for the public good, then there is no taking of property for the public use, and a right to compensation, on account of such injury, does not attach under the Constitution. Such is the present case.' The opinion concluded: 'Without further discussion we hold it to be the duty of the railway company, at its own expense, to remove from the creek the present bridge, culvert, timbers, and stones placed there by it, and also (unless it abandons or surrenders its right to cross the creek at or in the vicinity of the present crossing) to erect, at its own expense, and maintain, a new bridge for crossing that will conform to the regulations established by the drainage commissioners, under the authority of the state; and such a requirement, if enforced, will not amount to a taking of private property for public use within the meaning of the Constitution, nor to a denial of the equal protection of the laws.'


The latest adjudication by this court was in West Chicage Street R. Co. V. Chicago, 201 U. S. 506, 524, 50 L. ed. 845, 852, 26 Sup. Ct. Rep. 518, 523. In that case the principal question related to the duty of a street railroad company, which had lawfully constructed a tunnel under the Chicago river, to obey an ordinance of the city, requiring the company, at its own cost and expense, to lower its tunnel, so as to provide for a certain depth under it, which had been ascertained by competent Federal and local authority to be necessary for the increased demands of navigation. This court held, upon the adjudged cases, that the rights of the company, as the owner of the fee of the land on either side of the river or in its bed, were subject to the paramount right of navigation over the waters of the river. It said: 'If, then, the right of the railroad company to have and maintain a tunnel under the Chicago river is subject to the paramount public right of navigation; if its right to maintain a tunnel in the river is a qualified one, because subject to the specific condition in the act of 1874 that no tunnel should interrupt navigation; if the present tunnel is an obstruction to navigation, as, upon this record, we must take it to be; and if the city, as representing the state and public, may rightfully insist that such obstruction shall not longer remain in the way of free navigation,—it necessarily follows that the railway company is under a duty to comply with the demand made upon it to remove, at its own expense, the obstruction which itself has created and maintains. If the obstruction cannot be removed except by lowering the tunnel to the required depth and (if a tunnel is to be maintained) providing one that will not interrupt navigation, then the cost attendant upon such work must be met by the company. The city asks nothing more than that the railroad company shall do what is necessary to free navigation from an obstruction for which it is responsible, and (if it intends not to abandon its right to maintain a tunnel at or near Van Buren street) that it shall itself provide a new tunnel with the necessary depth of water above it.' Again: 'In the case before us the public demands nothing to be done by the railroad company except to remove the obstruction which itself placed and maintains in the river under the condition that navigation should not at any time be thereby interrupted. The removal of such obstruction is all that is needed to protect navigation. So that whatever cost attends the removal of the obstruction must be borne by the railroad company. The condition under which the company placed its tunnel in the river being met by the company, the public has no furthere demands upon it. This cannot be deemed a taking of private property for public use, or a denial of the equal protection of laws within the meaning of the Constitution, but is only the result of the lawful exercise of a governmental power for the common good. This appears from the authorities cited in Chicago, B. & Q. R. Co. v. Illinois, supra, just decided. The state court has well said that to maintain the navigable character of the stream in a lawful way is not, within the meaning of the law, the taking of private property or any property right of the owner of the soil under the river, such ownership being subject to the right of free and unobstructed navigation. People ex rel. Chicago v. West Chicago Street R. Co. 203 Ill. 551, 557, 68 N. E. 78. What the city asks, and all that it asks, is that the railroad company be required, in the exercise of its rights and in the use of its property, to respect the public needs as declared by competent authority, upon reasonable grounds, to exist. This is not an arbitrary or unreasonable demand. It does not, in any legal sense, take or appropriate the company's property for the public benefit, but only insists that the company shall not use its property so as to interrupt navigation.'


Do the principles announced in the above cases require us to hold, in the present case, that the making of the alterations of its bridge specified in the order of the Secretary of War will be a taking of the property of the Bridge Company for public use? We think not. Unless there be a taking, within the meaning of the Constitution, no obligation arises upon the United States to make compensation for the cost to be incurred in making such alterations. The damage that will accrue to the Bridge Company, as the result of compliance with the Secretary's order, must, in such case, be deemed incidental to the exercise by the government of its power to regulate commerce among the states, which includes, as we have seen, the power to secure free navigation upon the water ways of the United States against unreasonable obstructions. There are no circumstances connected with the original construction of the bridge, or with its maintenance since, which so tie the hands of the government that it cannot exert its full power to protect the freedom of navigation against obstructions. Although the bridge, when erected under the authority of a Pennsylvania charter, may have been a lawful structure, and although it may not have been an unreasonable obstruction to commerce and navigation as then carried on, it must be taken, under the cases cited, and upon principle, not only that the company, when exerting the power conferred upon it by the state, did so with knowledge of the paramount authority of Congress to regulate commerce among the states, but that it erected the bridge subject to the possibility that Congress might, at some future time, when the public interest demanded, exert its power by appropriate legislation to protect navigation against unreasonable obstructions. Even if the bridge, in its original form, was an unreasonable obstruction to navigation, the mere failure of the United States, at the time, to intervene by its officers or by legislation and prevent its erection, could not create an obligation on the part of the government to make compensation to the company if, at a subsequent time, and for public reasons, Congress should forbid the maintenance of bridges that had become unreasonable obstructions to navigation. It is for Congress to determine when it will exert its power to regulate interstate commerce. Its mere silence or inaction when individuals or corporations, under the authority of a state, place unreasonable obstructions in the water ways of the United States, cannot have the effect to cast upon the government an obligation not to exert its constitutional power to regulate interstate commerce except subject to the condition that compensation be made or secured to the individuals or corporation who may be incidentally affected by the exercise of such power. The principle for which the Bridge Company contends would seriously impair the exercise of the beneficent power of the government to secure the free and unobstructed navigation of the water ways of the United States. We cannot give our assent to that principle. In conformity with the adjudged cases, and in order that the constitutional power of Congress may have full operation, we must adjudge that Congress has power to protect navigation on all water ways of the United States against unreasonable obstructions, even those created under the sanction of a state, and that an order to so alter a bridge over a water way of the United States that it will cease to be an unreasonable obstruction to navigation will not amount to a taking of private property for public use for which compensation need be made.


Independent of the grounds upon which we thus place our decision, it is appropriate to observe that the conclusion reached finds support in the charter of the Bridge Company and in the law of Pennsylvania, as declared by its highest court. The charter of the company, as we have seen, expressly warned the company that its bridge must not obstruct navigation,—that is, in legal effect, navigation as it then was, or might be, at any subsequent time. In Dugan v. Bridge Co. 27 Pa. 303, 309, 311, 67 Am. Dec. 464, we have the case of a bridge company on which was conferred the franchise to erect and maintain a toll-bridge across Monongahela river, coupled, however, with the condition that such bridge should not be erected 'in such manner as to injure, stop, or interrupt the navigation of such river by boats, rafts, or other vessels.' The supreme court of Pennsylvania interpreted these words as meaning that 'the bridge was to be so built as not to injure, stop, or interrupt the navigation, either then or now, whether in its infancy or full growth.' The same general question arose in Chicago, B. & Q. R. Co. v. Illinois, 200 U. S. 589, 50 L. ed. 607, 26 Sup. Ct. Rep. 348. This court held that the adjudged cases 'negative the suggestion of the railway company that the adequacy of its bridge and the opening under it for passing the water of the creek at the time the bridge was constructed determine its obligations to the public at all subsequent periods. In Cooke v. Boston & L. R. Corp. 133 Mass. 185, 188, it appeared that a railroad company had statutory authority to cross a certain highway with its road. The statute provided that if the railroad crossed any highway it should be so constructed as not to impede or obstruct the safe and convenient use of the highway. And one of the contentions of the company was that the statute limited its duty and obligation to provide for the wants of travelers at the time it exercised the privilege granted to it. The court said: 'The legislature intended to provide against any obstruction of the safe and convenient use of the highway for all time; and if, by the increase of population in the neighborhood, or by an increasing use of the highway, the crossing, which, at the outset, was adequate, is no longer so, it is the duty of the railroad corporation to make such alteration as will meet the present needs of the public who have occasion to use the highway.' In Lake Erie & W. R. Co. v. Cluggish, 143 Ind. 347, 42 N. E. 743, the court said (quoting from Lake Erie & W. R. Co. v. Smith, 61 Fed. 885): 'The duty of a railroad to restore a stream or highway way which is crossed by the line of its road is a continuing duty; and if, by the increase of population or other causes, the crossing becomes inadequate to meet the new and altered conditions of the country, it is the duty of the railroad to make such alterations as will meet the present needs of the public.' So, in Indiana ex rel. Muncie v. Lake Erie & W. R. Co. 83 Fed. 284, 287, which was the case of an overhead crossing lawfully constructed on one of the streets of a city, the court said: 'If, by the growth of population or otherwise, the crossing has become inadequate to meet the present needs of the public, it is the duty of the railroad company to remedy the defect by restoring the crossing so that it will not unnecessarily impair the usefulness of the highway." Some stress was laid in argument upon the fact that compliance with the order of the Secretary of War will compel the Bridge Company to make a very large expenditure in money. But that consideration cannot affect the decision of the questions of constitutional law involved. It is one to be addressed to the legislative branch of the government. It is for Congress to determine whether, under the circumstances of a particular case, justice requires that compensation be made to a person or corporation incidentally suffering from the exercise by the national government of its constitutional powers.


These are all the matters which require notice at our hands; and, perceiving no error of law on the record, the judgment must be affirmed.


It is so ordered.
