Mr. Justice Day

delivered the opinion of the court.

The appellees in these four cases are corporations organized under state laws and engaged in the carriage of passengers and freight by water upon the Great Lakes. They filed bills in the United States Circuit Court for the Northern District of Illinois to enjoin the enforcement of certain orders of the Interstate Commerce Commission. The cases were afterwards transferred to the United States Commerce Court.

The orders of the Commission complained of comprise: First, an order prescribing the method of accounts and bookkeeping ás to the operating expenses of the carriers and a similar order as to bookkeeping concerning the operating revenues of the carriers; and, second, an order requiring a report of the carriers respecting their corporate organization, financial condition, etc.

The Government of the United States intervened and filed an answer in each case, but the cases were practically heard on demurrer, as the record discloses, and therefore the allegations of the bills well pleaded must be deemed to be true. The bills, contain many conclusions, and argumentative deductions as to the effect of the orders upon the carriers, which, under the rules of pleading, are not considered as admitted. United States v. Ames, 99 U. S. 35, 45.

The pertinent averments necessary to a decision of the cases, as we view them, show that the carriers are corporations organized under the laws of certain States of the Union; that they carry passengers, and freight upon the Great Lakes between ports in different States, which they designate as their port-to-port interstate business; that they carry passengers and freight wholly within a State, which they designate as their port-to-port intrastate business; and that they also carry passengers and property in interstate commerce under joint tariffs in connection with certain railroad carriers of the United States with whom they have agreed upon joint through rates., which they designate as their joint rail and water business. As to the Goodrich Transit Company, it is averred that eighty per cent of its .gross revenue is derived from its port-to-port interstate and intrastate business, and less than twenty per cent of its gross earnings is derived from its joint rail and water business. A like averment is made with respect to the White Star Line, except that it is said that in its business the revenue drived from joint .rail and water traffic, as .aforesaid, is less than one per cent of its entire revenue.

It is averred that the bookkeeping and accounting methods required by the orders of the Commission differ from those prescribed and now kept by the companies; that the orders of- the Commission make no difference between the intrastate port-to-port business and the interstate port-to-port business and the joint rail and water business; and that the orders entered by the Commission prohibit the companies from keeping-any accounts, records or memoranda other than those prescribed by the Commission in such orders.

In the White Star Line cases the bills contain an additional averment that that company operates two amusement parks, one at Tashmoo and one at Sugar Island, both in the State of Michigan, and in connection therewith owns, operates and derives revenue from lunch stands, merry-go-rounds, bowling alleys, bath houses, etc., and collects admission fees from people entering the parks. It complains that its business concerning said parks is included within the accounting methods prescribed by the Commission.

As to the report called for by the order of the Commission, it is averred that such report was not required, because of any complaint filed against the corporations for the violation of the Act to Regulate Commerce; that there is no statute requiring the report to be kept secret, and, if it is made public, the affairs of the companies will be thrown open to inspection to their injury; that a large number of the inquiries contained in the order of the Commission relate to details of the companies’ business solely intrastate, or that which is from port to port; and that the report is not limited to the joint rail and water business of complainants.

There are also averments that the orders were unconstitutional, because the Commission, in undertaking to put in force such requirements, exceeded its authority in so far as the power was asserted to examine into the af fairs of the companies not relating to their joint rail and water business, and having reference, as it was alleged, to their domestic business or interstate business not within the terms of the act.

The Commerce Court enjoined the execution of the orders (190 Fed. Rep. 943), declaring that (p. 966):

“It [the Commission] acted within its authority when it made an order calling for reports of all business done by the petitioners under through bills of lading where the transportation was partly by railroad from one State to another, or from one place in the United States to Canada, an adjacent foreign country; and it was within its power when it prescribed the system of accounts and the uniform method of keeping accounts for such interstate business, and so .far as the orders call for information confined to such traffic, or directly related thereto, and so far as the orders prescribe uniform systems of bookkeeping and accounting for such traffic and such as is directly related thereto, they must be sustained. But, in so far as the reports called for and the accounting rules prescribed extend beyond such interstate business of the carriers, or include matters of intrastate traffic accounts and affairs and concerns exclusively, they become invasions of the rights of the carriers, and to the extent of such invasions are unlawful.”

The court held that the orders concerning the report .and auditing would be lawful respecting the interstate business done by the carriers in connection with railroads, as provided by the act, but, in requiring a report concerning the other business of the companies and prescribing bookkeeping methods therefor, the Commission exceeded its authority, and the court granted the prayers of the petitioners for the orders of injunction, ordered a recast of the form of report in conformity with its opinion and remanded the cases to the Commission for that purpose.

Whether this order of the Commerce Court was correct or not primarily depends upon the construction of the Interstate Commerce Act and the extent to which, in the respect involved in these cases, the carriers herein interested are within the terms of the law. The terms of the act of Congress, as amended June 29, 1906, 34 Stat. 584, c. 3591, and in force at the time when these orders were made, are plain and simple, and, we think, not difficult to comprehend. They are: “The provisions of this act [to regulate commerce] shall apply to . . . any .common carrier or carriers engaged in the transportation of passengers or property wholly by railroad (or partly by railroad and partly by water when both are used under a common control, management, or arrangement for a continuous carriage or shipment), from one State or Territory of the United States, or the District of Columbia, to any other State or Territory of the United States, etc.” The proviso, at the end of the section, that its terms shall not apply to the transportation of passengers or property wholly within one State was inserted for the purpose of showing the congressional purpose not to undertake to regulate a commerce wholly domestic. The first section makes the act apply alike to common carriers engaged in the transportation of passengers or property wholly by railroad or partly by railroad and partly by water under an arrangement for a continuous carriage or shipment. It is conceded that the carriers filing the bills in these cases were common carriers engaged in the transportation of passengers and property partly by railroad and partly by water under a joint arrangement for a continuous carriage or shipment. Such common carriers are declared to be subject to the provisions of the act in precisely the same terms as those which comprehend the other companies named in the act. Carriers partly by railroad and partly by water under a common arrangement for a continuous carriage or shipment are as specifically within the terms of the act as any other carrier named therein. It may be that certain provisions of the act are in their nature applicable to some carriers and not to others; but we are only concerned to inquire in this case whether the carriers thus broadly brought within the terms of the act by § 1 thereof are subject to the provisions of the statute by the authority of which, the Commission undertook to require the system of accounting and the report as to the organization and business of the corporations, and whether, if within the terms of the act, the orders are constitutionally made.

Certain it is that, when engaged in carrying on traffic under joint rates with railroads, filed with the Commission, the carriers are bound to deal upon like terms with all shippers who seek to avail themselves of such joint rates, and are subject to the general requirements of the act preventing and punishing the giving of rebates, the making of unjust discriminations, the showing of favoritism and other practices' denounced in the various sections of the act. They are undoubtedly subject to the provisions taf § 12 of the act, which permits the Commission to inquire into the management of the business of all common carriers subject to the act and to keep itself informed as to the manner and method in which the same is conducted, with the right to obtain from such common carriers the full and complete information necessary to enable the Commission to carry out the objects for which it was created. The joint rates established are subject to revision by the Commission under § 15 of the act. We must remember, also, in this connection, that under § 21 of the act the Commission is required to make a report each year to the Congress containing such information and. data as may be considered of value in the determination of questions connected with the regulation of commerce, together with such recommendations as to additional legislation as the Commission may see fit to make.

As to annual reports, the power conferred in § 20 of the act extends to all common carriers subject to the provisions of the act. The Commission is vested with authority to prescribe the manner in which such reports shall be made and to require specific answers-to all questions as to which the Commission may need information. The report required in these cases was declared to be needed to enable the Commission to procure full information of the scope and character of the business of carriers by water within the jurisdiction of the Commission and of the extent of their operations, such as would enable the Commission to determine the form for annual report which would best give the information required by the Commission, and at the same time conform as nearly as may be to the accounting systems of carriers by water.

The form of report adopted by the Commission requires a showing as to the corporate organization of each carrier by water subject to the act, the companies owned by it and the parties or companies controlling it; as to the financial condition of 'the carrier, the cost of its real property and equipment, its capital stock and other stock and securities owned by it, together with all special funds and current assets and liabilities, as well as its funded indebtedness, with collateral security covering same; and as to finances with respect to the operations of the carrier for the current year, giving the revenue of the company and its source, whether from transportation, and what kind, or from outside operations, and all expenses, detailed, with a statement as to the net income’or deficit from the various sources, and the report contains a profit and loss account and a general balance sheets The report further requires certain statistical information, as follows: The routes of the carrier and their mileage; a general description of the equipment owned, leased or chartered by the carrier; the amount of traffic, both passenger and freight, and mileage and revenue statistics, together with a separation of freight into the quantity of the various products transported, showing also whether originating on the carrier’s line or received.from a connecting line; and a general description of any separate business carried on by the carrier. But such report is no broader than the annual report of such carriers, as prescribed by the act, for § 20 provides that:

“Such annual reports shall show in detail the amount of capital stock issued, the amounts paid therefor, and the manner of payment for the same; the dividends paid, the surplus fund, if any, and the number of stockholders; the funded and floating debts and the interest paid thereon; the cost and value of the carrier’s property, franchises, and equipments; the number of employés and the salaries paid each class; the accidents to passengers, employés, and other persons, and the causes thereof; the amounts expended for improvements each year, how expended, and the character of such improvements; the earnings and receipts from each branch of business and from all sources; the operating and other expenses; the balances of profit and loss; and a complete exhibit of the financial operations of the carrier each year, including an annual balance sheet. Such reports shall also contain such information in relation to rates or regulations concerning fares or freights, or agreements, arrangements, or contracts affecting the same as the Commission may require.”

As to the accounts, the statute permits the Commission, in its discretion, for the purpose of enabling it the better to carry out the purposes of the act, to prescribe a period of time within which such common carriers shall have a uniform system of accounts and the manner in which such accounts shall be kept. The Commission may, the statute further provides, in its discretion, prescribe the forms of all accounts, records and memoranda to be kept by the common carriers, to which accounts the Commission shall have access. And the act makes it unlawful for the carriers to keep any accounts, records or memoranda other than those prescribed by the Commission.

We think this section contains ample authority for the Commission to require a system of accounting as provided in its orders and a report in the form shown to have been required by the order of the Commission. It is true that the accounts required to be kept are general in their nature and embrace business other than such as is necessary to the discharge of the duties required in carrying passengers and freight in interstate commerce by joint arrangement between the railroad and the water carrier, but the Commission is charged under the law with the supervision of such rates as to their reasonableness and with the general duty of making reports to Congress which might require a knowledge of the business of the carrier beyond that which is strictly of the character mentioned. If the Commission is to successfully perform its duties in respect to reasonable rates, undue discriminations and favoritism, it must be informed as to the business of the carriers by a system of accounting which will not permit the possible concealment of forbidden practices in accounts which it is not permitted to see and concerning which it can require no information. It is a mistake to suppose that the requiring of information concerning the business methods of such corporations, as shown in their accounts, is a regulation of business not within the jurisdiction of the Commission, as seems to be argued for the complainants. The object of requiring such accounts to be kept in a uniform way and to be open to the inspection of the Commission is not to enable it to regulate the affairs of the corporations not within its jurisdiction, but to be informed concerning the business methods of the corporations subject to the act that it may properly regulate such matters as are really within its jurisdiction. Further, the requiring of information concerning a business is not regulation of that business. The necessity of keeping such accounts has been developed in the reports of the Commission and has been the subject of great consideration. It caused the employ ment of those skilled in such matters, and has resulted in the adoption of a general form of accounting which will enable the Commission to examine into the affairs of the corporations, with a view to discharging its duties of regulation concerning them.

There is nothing in the case of Harriman v. Interstate Commerce Commission, 211 U. S. 407, contrary to the conclusion herein announced. That case dealt with the authority of the Commission to compel the attendance and testimony of witnesses in cases where complaints had not been made. The extent to which the Commission might require systems of accounting and reports of corporations subject to the act was expressly left open in the opinion of the court. 211 U. S. pp. 421, 422.

The necessity of such accounts is emphasized under the English practice, and accounts and reports are required in great detail under the laws of that country.

In the report of the committee appointed by the Board of Trade under the Railway Regulation Acts to make inquiries with respect to the form and scope of the accounts and statistical returns rendered by railway companies the omission of the former law to make provision for any prescribed and uniform system of accounts is pointed out, and it is said:

“It is obviously of the first importance, from the point of view of comparison between the different railway companies, that there should be uniformity of practice among all the companies with regard to the keeping of accounts and statistics; that is to say, that every heading, both in the accounts and in the statistics, should bear precisely the same meaning in the case of all railways— should, in effect, be standardized.”

The Railway Companies (Accounts and Returns) Act, December 16, 1911, 1 and 2 Geo. 5, c. 34, — to amend the laws with respect to accounts and returns of railway companies — contains requirements as to finan cial accounts and statistical returns which call for a uniform system of accounting, showing the organization and workings of the companies in great detail, together with statistical returns as to their business, subdivided so as to include all the operations of the companies as carriers and in all other enterprises in which they may engage.

The learned Commerce Court was of the opinion that the Commission might require accounts and reports, so far as the business of the water carriers with reference to joint rates by rail and water under a common arrangement was concerned, and remanded the cases to the Commission for revision of their orders upon that basis. But it is argued for the Commission, and it seems to us with great force, that it would be impracticable to make such separation in any system of accounting. It is a matter of general knowledge, of which we may take judicial notice, that traffic of all kinds is conducted upon the same ship and passage. A boat may leave a lake port carrying passengers and freight destined for ports within the State and for ports beyond the State, and as a part of the freight for carriage embrace some carried under the terms of joint arrangements made with connecting railroad carriers. How would it be practicable to separate the items of expense entailed in the carriage of these various classes? It is done upon one boat, with one set of officers and crew, and must, in the nature of things, be under one general bill of expense — at least it would seem impracticable to separate it into its items so as to show the expense of that which it is contended is alone within the terms of the act, as construed by the carriers.

We think the act should be given a practical construction, and one which will enable the Commission to perform the duties required of it by Congress, and, conceding for this purpose that the regulating power of the Commission is limited so far as rates are concerned to joint rates of the character named in § 1, it is still essential that to enable the Commission to perform its required duties, even with respect to such rates, and to make reports to Congress of'the business of carriers subject to the terms of the act, it should be informed as to the matters contained in the report. Congress, in § 20, has authorized the Commission to inquire as to the business which the the carrier dees and to require the keeping of uniform accounts, in order that the Commission may know just how the business is carried on, with a view to regulating that which, is confessedly within its power.

It is contended that this construction of the statute enables the Commission not only to regulate the interstate business, but as well the wholly intrastate business of the complaining corporations, and is, therefore, beyond the power of Congress. Such cases are cited and relied upon by complainants as the Employers’ Liability Cases, 207 U. S. 463, and Illinois Central R. R. Co. v. McKendree, 203 U. S. 514. In those cases acts of Congress and orders of executive departments were held void because they undertook to regulate matters wholly intrastate, as distinguished from those matters of an interstate character and within the legislative power of Congress. And what we have already said as to the character of these orders is enough to indicate that in our opinion they are not regulations of intrastate commerce.

Furthermore, it is said that such construction of § 20 makes it an unlawful delegation of legislative power to the Commission. We cannot agree to this contention. The Congress may not delegate its purely legislative power to a commission, but, haying laid down the general rules of action under which a commission shall proceed, it may require of that commission the application of suqh rules to particular situations and the investigation of facts, with a view to making orders in. a particular matter within the rules laid down by the Congress. This rule has been frequently stated and illustrated in recent cases in this court, and needs no amplification here. Buttfield v. Stranahan, 192 U. S. 470; Union Bridge Co. v. United States, 204 U. S. 384; United States v. Grimaud, 220 U. S. 506.

In § 20 Congress has authorized the Commission to require annual reports. The act itself prescribes in detail what those reports shall contain. The Commission is permitted, in its discretion, to require a uniform system of accounting, and to prohibit other methods of accounting than those which the Commission may prescribe. In other words, Congress has laid down general rules for the guidance of the Commission, leaving to it merely the carrying out of details in the exercise of the.power so conferred. This, we think, is not a delegation of legislative authority.

And it is argued that Congress has no visitorial power over state corporations. We need not reassert - the ample power which the Constitution has been construed to confer upon Congress in the regulation of interstate commerce, declared in the many cases in this court, from Gibbons v. Ogden, 9 Wheaton, 1, to its most recent deliverances. In Hale v. Henkel, 201 U. S. 43, 75, while general visitorial power over state corporations was not asserted to be within the power of Congress, it was nevertheless declared as. to interstate commerce that the General Government had, in the vindication of its own laws, the same power it would possess if the corporation had been created by act of Congress.

As to one of the corporations it is said that its business includes not only the carriage of passengers and freight, but that it owns and operates in connection therewith certain, amusement parks. The report in controversy, as to business other than commerce, requires a general description of such outside operations, and also a statement of the income from and the expenses of the same. As we have said, if the Commission is to be informed of the business of the corporation, so far as its bookkeeping and reports are concerned, it must have full knowledge and full disclosures thereof, in order that it may ascertain whether forbidden practices and discriminations are concealed, even unintentionally, in certain accounts and whether charges of expense are made against one part of a business which ought to be made against another.

Bookkeeping, it is said, is not interstate commerce. True, it is not. But bookkeeping may and ought to show how a business which, in part at least, is interstate commerce, is carried on, in order that the Commission, charged with the duty of making reasonable rates and prohibiting unfair and unreasonable ones, may know the nature and extent of the business of the corporation, the cost of its interstate transactions and otherwise to inform itself so as to enable.it to properly regulate the matters which are within its authority.

We think the uniform system of accounting prescribed and the report called for are such as it is within the power of the Commission to require under § 20 of the act. Nor do the requirements exceed the constitutional authority of Congress to pass such a law. It therefore follows that the Commerce Court erred in granting the injunctions and in remanding the cases to the Commission with instructions to recast its orders.

Judgments reversed.

Dissenting, Mr. Justice Lurton and Mr. Justice Lamar.
