Mr. Justice Day
delivered the opinion of the court.
A bill was filed in the. United States District Court for the Western Division of the Western District of Missouri by a shareholder in the Kansas City Title & Trust Company to enjoin the Company, its officers, agents and employees from investing the funds of the Company in farm loan bonds issued by Federal Land Banks or Joint Stock Land Banks under authority of the Federal Farm Loan Act of July 17, 1916, c. 245, 39 Stat. 360, as amended January 18,1918, c. 9, 40 Stat. 431.
The relief was sought on the ground that these acts were beyond the constitutional power of Congress. The bill avers that the Board of Directors of the Company are [196]*196about to invest its funds in the bonds to the amount of $ 10,000 in each of the classes described, and will do so unless enj oined by the court in this action. The bill avers the formation of twelve Federal Land Banks, and twenty-one Joint Stock Land Banks under the provisions of the act.
As to the Federal Land Banks, it is averred that each of them has loaned upon farm lands large amounts secured by mortgage, and, after depositing the same with the Farm Loan Registrar, has executed and issued collateral trust obligations called Farm Loan Ronds, secured by the depositing of an equivalent amount of farm mortgages and notes; and that each of said Federal Land Banks has sold, and is continuing to offer for sale, large amounts of said Farm Loan Bonds. The bill also avers that various persons in different parts of the United States have organized twenty-one Joint. Stock Land Banks, the capital stock of which is subscribed for and owned by private persons; that the Joint Stock Land Banks have deposited notes and mortgages with the Farm Loan Registrar, and issued an equivalent amount of collateral trust obligations called Farm Loan Bonds, which have been sold and will be continued to be offered for sale to investors in large amounts in the markets of the country. A statement is given of the amount of deposits by the Secretary of the Treasury with the Federal Land Banks, for which the banks have issued their certificates of indebtedness bearing interest at 2%.' per annum. It is averred that on September 30, 1919, Federal Land Banks owned United States bonds of the par value of $4,230,805; and the Joint Stock Land Banks owned like bonds of the par value of $3,287,503 on August 31, 1919; that pursuant to the provisions of the act the Secretary of the Treasury has invested $8,892,130 of the public funds in the capital stock of the Federal Land Banks, and that on July 1, 1919, the Secretary of the Treasury on behalf of the United States held $8,265,809 of the capital stock of the Federal Land Banks; [197]*197that pursuant to the provisions of § 32 of the act, as amended, the Secretary of- the Treasury has purchased Farm Loan Bonds issued by the Federal Land Banks of the par value of $149,775,000; that up to September 30, 1919, bonds have been issued under the act by the Federal Land Banks to the amount of $285,600,000, of which about $Í35,000,000 are held in the Treasury of the United States, purchased under the authority of the amendment of January' 18, 1918; that up to September 30, 1919, twenty-seven Joint Stock Land Banks have been incorporated under the act, having an aggregate capital of $8,000,000, all of which has been subscribed and $7,450,000 paid in; that bonds have been issued by Joint Stock Land Banks to the amount of $41,000,000, which are now in the hands, of the public;'that the Secretary of the Treasury up to the time of the filing of the bill has not designated any of the Federal -Land Banks nor the Joint Stock Land Banks as depositaries of. public money,, nor, except as stated later in the. bill., has he employed them or any of them as financial agents of the Government, nor have they or any of them performed any duties as depositaries of public money, nor have they or any of them accepted any deposits or engaged in any banking business. The bill avers that during the summer of 1918 the Federal Land Banks at Wichita; St. Paul and Spokane were designated as financial agents of the Government for making seed grain loans to farmers in drought-stricken sections, the President having at the request of the Secretary of Agriculture set aside $5,000,000 for that purpose out' of the $100,000,000 war funds. The three banks mentioned made upwards of 15,000 loans of-that character, aggregating a sum upwards of $4,500,000, and are now engaged in collecting these loans, all of which are secured by crop liens; that these banks act in that capacity without compensation, receiving only the actual expenses incurred.
Section 27 of the act provides- that Farm Loan Bonds [198]*198issued under the provisions of the act by Federal Land Banks or Joint Stock Land Banks shall be a lawful investment for all fiduciary and trust funds, and may be accepted as security for all public deposits. The bill avers that' the defendant Trust Company is authorized to buy, invest in and sell government, state and municipal and other bonds, but it cannot buy, invest in or sell any such bonds, papers, ..stocks or securities which are not authorized to be issued by a valid law or which are not investment securities, but that nevertheless it is about to invest in Farm Loan Bonds; that the Trust Company has been induced to direct its officers to make the investment by reason of its reliance upon the provisions of the Farm Loan Acts, especially §§21, 26 and 27, by which the Farm Loan Bonds are declared to be instrumentalities of the Government of the United States, and as such with the income derived there,from, are declared to be exempt from federal, state, municipal and local taxation, and are further declared to be lawful investments for ail fiduciary and trust funds. The bill further avers that the acts by which it is attempted to authorize the bonds are wholly illegal, void and unconstitutional and of no effect because unauthorized' by the Constitution of the United States.
The bill pra^s that the acts of Congress authorizing the creation of the banks, especially §§ 21, 26 and 27 thereof, shall be adjudged and decreed to be unconstitutional, void and of no effect, and that the issuance of the Farm Loan B<pnds, and the taxation exemption feature thereof, shall be adjudged and decreed to be invalid;
The First Joint Stock Land Bank-of Chicago and the Federal Land Bank of Wichita,.. Kansas, were allowed to intervene and became parties defendant to the. suit. The Kansas City Title & Trust Company filed a motion to dismiss in the nature of a general demurrer, and upon hearing the District Court entered a decree dismissing the bill. From this decree appeal was taken to this court.
[199]*199No objection is made to the federal jurisdiction, either original or appellate, by the parties to this suit, but that question will be first examined. The Company is authorized to invest its funds in legal securities only. The attack upon the proposed investment in the bonds described is because of the alleged unconstitutionality of the acts of Congress undertaking to organize the banks and authorize the issue of the bonds. No other reaspn is set forth in the bill as a ground of objection to the proposed investment by the Board of Directors acting in the Company’s behalf. As diversity of citizenship is. lacking, the jurisdiction of the District Court depends upon whether the cause of action set forth arises under the Constitution or laws of the United States. Judicial Code, § 24.
The general rule is that where/it appears from the-bill or statement of the plaintiff that the right to relief depends upon the construction or application of the Constitution or laws of the United States, and that such federal claim is not merely colorable, and rests upon a reasonable foundation, the District Court has jurisdiction under this provision.
At an early date, considering the grant of constitutional power to confer jurisdiction upon the federal courts, Chief Justice Marshall said: “A case in law or equity consists of the right of the one party, as well as of the other, and may truly be said to arise under the Constitution or a law of the United States, whenever its correct decision depends on the construction of either, ” Cohens v. Virginia, 6 Wheat. 264, 379; and again, when “the title or right set up by the party may be defeated by one construction of the Constitution or law of the United States, and sustained by the opposite construction. ” Osborn v. Bank of the United States, 9 Wheat. 738, 822. These definitions were quoted and approved in Patton v. Brady, 184 U. S. 608, 611, citing Gold-Washing Co. v. Keyes, 96 U. S. 199, 201; Tennessee v. Davis, 100 U. S. 257; White v. Greenhow, 114 U. S. 307; Railroad Company v. Mississippi, 102 U. S. 135, 139.
[200]*200This characterization of a suit arising under the Constitution or laws of the United States has -been followed in many decisions of this and other federal courts. See Macon Grocery Co. v. Atlantic Coast Line R. R. Co., 215 U. S. 501 506, 507; Shulthis v. McDougal, 225 U. S. 561, 569, paragraph 3. The principle was applied in Brushaber v. Union Pacific R. R. Co., 240 U. S. 4, in which a shareholder filed a bill to enjoin the defendant corporation from complying with the income tax provisions of the Tariff Act of October 3, 1913. In that case while there was diversity of citizenship, a direct appeal to. this court was sustained because of the constitutional questions raised in the bill, which had been dismissed by the court below. The repugnancy of the statute to the Constitution of the United States, as well as grounds of equitable jurisdiction, were set forth in the bill, and the right to come here on direct appeal was sustained because of the averments based upon constitutional objections to the act.' Reference was made to Pollock v. Farmers’ Loan & Trust Co., 157 U. S. 429, where a similar shareholder’s right to sue was maintained, and a direct appeal to this court from a decree of the Circuit Court was held to bé authorized.
In the Brushaber Case the Chief Justice, speaking for the court, said:
“The right-to prevent the. corporation from returning- and. paying the tax was based upon many averments as to the repugnancy ofi-the statute to the Constitution of the United States, of the peculiar relation of the corporation to the.stockholders and their particular interests resulting from many of the administrative provisions of the assailed act, of the confusibn, wrong-and multiplicity of suits and the absence of all means of redress which would result if the corporation paid the tax and complied with the act in other respects without -protest, as it was alleged it was its intention to do. To put out of the way a question of jurisdiction we'at once say that in view of these averments and [201]*201the ruling in Pollock v. Farmers’ Loan & Trust Co., 157 U. S. 429, sustaining the right of a stockholder to sue to restrain a corporation under proper averments from voluntarily paying á tax charged to be unconstitutional on the ground that to permit such a suit did not violate the prohibitions of § 3224, Rev. Stat., against enjoining the enforcement of taxes, we are of opinion that the contention here made that there was no jurisdiction of the cause since to entertain it would violate the provisions of the Revised Statutes referred to is without merit. ...
“Aside from averments as to citizenship and residence, recitals as to the provisions of the statute and statements as to the business of the corporation contained in the first ten paragraphs of the bill.advanced to sustain jurisdiction, the bill alleged twenty-one constitutional objections specified in that number of paragraphs or subdivisions. As all the grounds assert a violation of the Constitution, it follows that in a wide sense they all charge a repugnancy of the statute to the Sixteenth. Amendment under the more immediate sanction of which the statute was adopted. ”
The jurisdiction of this court is to be determined upon the principles laid down in the cases referred to. In the instant case the averments of the bill show that the directors were proceeding to make the investments in view of the act authorizing the bonds about to be purchased, maintaining that the act authorizing them was constitutional and the bonds valid and desirable investments. The objecting shareholder avers in the bill that the securities were issued under an unconstitutional law, and hence of no validity.- It is, therefore, apparent that the controversy. concerns the constitutional validity of an act of Congress which is directly drawn in question. The decision depends upon the determination of this issue.
The general allegations as to the interest of the shareholder, and his right to have an injunction to prevent the purchase of the alleged unconstitutional securities by mis[202]*202application of the funds of the corporation, give jurisdiction under the principles settled in Pollock v. Farmers’ Loan & Trust Co., and Brushaber v. Union Pacific R. R. Co., supra. We are, therefore, of the opinion, that the District Court had jurisdiction under the averments of the bill, and that a direct appeal to this court upon. constitutional grounds is authorized.
We come to examine the questions presented by the attack upon the constitutionality of the legislation in question. The Federal Farm Loan Act is too lengthy to set out in full. It is entitled: “An Act To provide capital for agricultural development, to create standard forms of investment based upon farm mortgage, to equalize, rates of interest upon farm loans, to furnish a market for United States bonds, to'create Government depositaries.and financial agents for the United States, and for other purposes. ”
The administration of the act ia placed under the direction and control of a Federal.. Farm Lpan Bureau established at. the seat of Government in the Treasury Department, under the general supervision of the Federal Farm Loan Board, consisting of the Secretary of the Treasuiy and four members appointed by the President by and with the advice and consent of the Senate. .- The United States is divided into twelve districts for the purpose of establishing.Federal Land Banks. Each of the banks must have á subscribed capital of not less than $750,000, divided into shares of $5.00 each, which may bé subscribed for by any individual, firm or corporation, or by the government of any State, or of the United States. No'dividends shall be paid on the stock owned by the United States, but all other stock shall share in dividend distributions without preference. " The Federal Farm Loan Board is to designate five directors who sha.ll temporarily, manage the affairs of each Federal Land Bank,-and who shall prepare an organization . certificate which, , when approved by the Federar Farm Loan Board and filed with the Farm Loan Commissioner, [203]*203shall operate to create the bank a body corporate. The ♦Federal Farm Loan Board is required to open books of-subscription for the capital stock of each Federal Land Bank, and, if within thirty days thereafter any part of the minimum capitalization of $750,000 of any such bank shall remain unsubscribed, it is made the duty of the Secretary of the Treasury to subscribe the balance on behalf of the United States.
The amendment of January 18, 1918, authorizes the -Secretary of the Treasury to purchase bonds issued by Federal Land Banks, and provides that the temporary organization of any such bank shall be continued so long as any Farm Loan Bonds shall be held by the Treasury, and until the subscription to stock in such bank by National Farm Loan Associations shall equal, the amount of the stock held by the United States Government. When . these conditions are complied with a permanent organization is to take over the management of the bank consisting of á Board of Directors composed of nine members, three of whom shall be known as district directors and shall be appointed by the Farm Loan Board, who shall represent the public interest, six of whom to be known as local directors, shall be chosen by, and be representative of National Farm Loan Associations.
Federal Land Banks are empowered to invest their funds in the purchase of qualified first mortgages on. farm lands situated within the Federal Land Bank District within which they are organized or acting. Loans on farm mortgages are to be made to cooperative borrowers through the organization of corporations known as National Farm Loan Associations, by persons desiring to borrow money on farm mortgage security under the terms of the a ct. Ten or more natural persons who are the owners of or aré about to become the owners of farm land qualified as security for mortgage loans, and who desire to borrow money on farm mortgage security, may unite to form a National Farm [204]*204Loan Association.' The manner of forming these associa-tions, and the qualifications for membership, are set out in the act.
A loan desired by each such person must be for not more than $10,000 nor less than $100, and the aggregate of the desired loans not less than. $20,000. The application for loan must be accompanied by subscriptions to stock of a Federal Land Bank equal to 5% of the aggregate sum desired on the mortgage loan. Provision is made for appraisal of the land, and report to the Federal Farm Loan Board.. No persons but borrowers on farm loan mortgages shall be members or shareholders of National Farm Loan Associations.
Shareholders in Farm Loan Associations are made individually responsible for the debts of the Association to the extent of the amount of the stock owned by them respectively, in addition to the amount paid in and represented by their shares.
When any National Farm Loan Association shall desire to secure for any member a loan on first mortgage from the Federal Land Bank in its district, it must subscribe to the capital stock of the Federal Land Bank4o an amount of 5% of such loan, which capital stock shall be held by the Federal Land Bank as collateral security for the payment of the loan, the Association shall be paid any dividends accruing and payable on the capital stock while it is outstanding. Such stock may, in the discretion of the directors and with the approval of the Federal Farm Loan Board, be paid off at par and retired, and shall be so retired upon the full payment of the mortgage loan. In such event, the National Farm Loan Association must pay off at par and retire the corresponding shares of its stock which- were issued when the Land Bank stock so retired was issued; but it is further provided that the capital stock of the Land Bank shall not be reduced to less than 5% of the principal of the outstanding Farm [205]*205Loan Bonds issued by it. The shares in National Farm Loan Associations shall be of the par value of $5.00 each.
At least 25% of that part of the capital of any Federal Land Bank for which stock is outstanding in, the name of National Farm Loan Associations must be held in quick assets. Not less than 5% of such capital must be invested in United States Government Bonds.
The loans which Federal Land Banks may make upon first mortgages oh farm lands-are provided for in § 12 of the act. By § 13 these banks are empowered, subject to the provisions of the act, to issue and sell Farm Loan Bonds of the kind described in the act, and to invest funds, in their possession in qualified first mortgages on farm lands, to receive and to deposit in trust with the Farm Loan Registrar, to be held by him as collateral security for Farm Loan Bonds, first mortgages upon farm lands, and, with the approval of the Farm Loan Board, to issue and to sell their bonds secured by the deposit of first mortgages on qualified farm lands as collateral, im conformity with the provisions of §. 18 of the act. By. the amendment of January .18, 1918, the Secretary of the Treasury was empowered during the years 1918 and 1919, to purchase Farm Lqan Bonds issued by Federal Land Banks to an amount not exceeding $100,000,000 each year, and any Federal Land Bank was authorized at anytime to repurchase at par and accrued interest, for the purpose of. redemption or resale, any of the bonds so purchased from, it and held in the United States Treasury.
It-is also provided that the bonds of any Federal Land Bank so purchased and held in the Treasury one year after the.termination of the pending war shall, upon’thirty days’, notice from the Secretary of the Treasury, be redeemed and repurchased by such bank at par and accrued interest. By § 15 it is provided that whenever, after the act shall have been in effect for one year, it shall appear to the Federal Farm Loan Board that National Farm Loan [206]*206Associations have not been formed and are not likely to be formed, in any locality, because of peculiar local conditions, the Board may in its discretion authorize Federal Land Banks to make loans on farm lands through agents approved by the. Board, on the terms and conditions and subject to the restrictions prescribed in that section.
' The act also authorizes the incorporation of Joint Stock Land Banks, with capital provided by private^ subscription. They are organized by not less than ten natural persons, and are subject to the requirements of the profusions of § 4 of the act so far as applicable.' The board of direc-. tors shall consist of not less than five members. Each shareholder shall have the same voting privileges as the holders of shares in National Banking Associations, and shall be held individually responsible, equally and ratably, and mot one for another, for all contracts, debts, and engagements of such bank to the extent of the amount of stock owned by them at the par value thereof, in addition to the amount paid in and represented by their shares. The' Joint Stock Land Bank is authorized to do business when capital stock to the amount of $250,000 has been sub-‘ scribed, and one-half paid in cash, the balance remaining subject to call by the board of directors, the charter to be issued by the Federal Farm Loan Board. No bonds shall be issued until the capital stock is entirely paid up. Except as otherwise provided, Joint Stock Land Banks shall have the powers of and be subject to all the restrictions and conditions imposed on Federal Land Banks by the act, so far as such conditions or restrictions are applicable.
Federal Land Banks may issue Farm Loan Bonds up to twenty times their capital and surplus. Joint Stock Land Banks are limited to the issue of Farm Loan Bonds not in excess of fifteen times the. amount of their capital .and surplus. Joint Stock Land Banks can only loan on first mortgages upon land in the State where located, or in a State [207]*207contiguous thereto. No loan on mortgage may be made by any bank at a rate exceeding 6% per annum exclusive of amortization payments. Joint Stock Land Banks shall in no case charge a rate of interest on farm loans which shall exceed by more than 1% the rate established by the last series of Farm Loan Bonds issued by them, which rate shall not exceed‘5% per annum.
Provisions for the issue of Farm Loan Bonds secured by first mortgages on farm lands or United States bonds, as collateral, are made for Federal Land Banks and Joint Stock Land Banks; in each case the issue is made subject to the approval of the Federal Farm Loan Board. The farm loan mortgages, or United States bonds, which constitute the collateral security for the bonds, must be deposited with the Farm Loan Registrar.
Section 26 of the act provides as follows: “That every Federal land bank and every national farm loan association, including the capital and reserve or surplus therein and the income derived therefrom, shall be exempt from Federal, State, municipal, and local taxation, except taxes upon real estate held, purchased,, or taken by said bank or association under the provisions of section eleven and section thirteen of this Act. First mortgages executed to Federal land banks, or to joint stock land banks, and farm loan bonds issued under, the provisions of this Act, shall be deemed and held to be instrumentalities of the Government of the United States, and as such they and the income derived therefrom shall be exempt from Federal, State, municipal, and local taxation.
“Nothing herein shall prevent the shares in any joint stock land bank from being included in the valuation of the personal property of the owner or holder of such shares, in assessing taxes imposed by authority of the State within which the bank is located;.but such assessment and taxation shall be in manner and subject to the conditions and limitations contained in section fifty-two [208]*208hundred and nineteen of the Revised Statutes with reference to the shares of national banking associations.
“Nothing herein shall be construed to exempt the real property of Federal and joint stock land banks and national farm loan associations from either State, county, or municipal taxes, to . the same extent, according to its value, as other real property is taxed.”
Since the decision of .the great cases of McCulloch v. Maryland, 4 Wheat. 316, and Osborn v. Bank, 9 Wheat. 738, it is no longer an open question that Congress may establish banks for national purposes, only a small part of the capital of which is held by the Government, and a majority of the ownership in which is represented, by shares of capital stock privately owned and held; the principal business of such banks being private banking conducted with the usual methods of such business. While the express power to create a bank or incorporate one is not found in the Constitution, the court, speaking by Chief Justice^ Marshall, in McCulloch v. Maryland, found, authority so to' do in the broad general-powers conferred by the Constitution upon the Congress to.levy and collect taxes, to borrow money, to regulate commerce, to pay the public debts, to declare and conduct war, to. raise and support armies, and to provide and maintain a navy, etc. Congress it was held had/ authority to use such means as were deemed appropriate to exercise the great powers of the Government by virtue of Article I, § 8, cl. 18, „of the Constitution granting to Congress the right to make all laws necessary and proper to make the grant effectual. In First National Bank v. Union Trust Co., 244 U. S. 416, 419, the Chief Justice, speaking for the court; after reviewing McCulloch v. Maryland, and OsbctM v. Bank, and considering the power given to Congress to pass laws to make the specific powers granted effectual, said:.
“In terms it was pointed out that this broad authority [209]*209was not stereotyped as of any particular time but endured, thus furnishing a perpetual and living sanction to the legislative authority within the limits of a just discretion enabling it to take into consideration the changing wants and demands of society and to adopt provisions appropriate to meet every situation which it was deemed required to be provided for.”
That the formation of the bank was required in the judgment of the Congress for the fiscal operations of the Government, was a principal consideration upon which Chief Justice Marshall rested the authority to create the bank; and for that purpose being an appropriate ■measure in the judgment of the Congress, it was held not to be within the authority of the court to question the conclusion reached by the legislative branch of the Government.
Upon the authority of McCulloch v. Maryland, and Osborn v. Bank, the national banking system was established, and upon them this court has rested the- constitutionality of the legislation establishing such banks. Farmers’ & Mechanics’ National Bank v. Dearing, 91 U. S. 29, 33, 34.
Congress has seen fit in § 6 of the act to make both classes of banks, when designated for that purpose by the Secretary of the Treasury, depositaries of public money, except receipts from customs, under regulations to be prescribed by the Secretary of the Treasury, and has authorized their employment as -financial agents of the Government, and the banks are required- to perform such reasonable duties, as depositaries of public moneys and financial agents' as may be required of them. The Secretary of the Treasury' shall require of the Federal Land Banks and the Joint Stock Land Banks, thus designated, satisfactory security, by the deposit of United States bonds or otherwise, for the safe-keeping and prompt payment of the public money deposited with them, and [210]*210for the faithful performance of their duties as the finan-? cial agents of the Government.
Section'6. also provides that no government funds deposited under the provisions of the section shall be invested in mortgage loans ór Farm Loan Bonds.
It is said that the power to designate these banks as such depositaries has not been exercised by the Government, and that the Federal Land Banks have acted as federal agents only in the case of loans of money for seed purposes made in the summer of 1918, to which we have already referred. But the existence of the power under the Constitution is not determined by the extent of the exercise of the authority conferred under it. Congress declared it necessary to create these fiscal agencies, and to make them authorized depositaries of public money. Its power to do so is no longer open to question.
But, it is urged, the attempt to create these federal agencies, and to make these banks fiscal agents and public depositaries of the Government, is but a pretext. But nothing is better settled by the decisions of this court than that, when Congress acts within the limits of its constitutional authority, it is'not the province of the judicial branch of the Government to question its motives. Veazie Bank v. Fenno, 8 Wall. 533, 541; McCray v. United States, 195 U. S. 27; Flint v. Stone Tracy Co., 220 U. S. 107, 147, 153, 156, and cases cited.
That Congress has seen fit, in making these banks fiscal agencies and depositaries of public moneys, to grant to them banking powers of a limited character, in'nowise detracts from the authority of Congress to use them for the governmental purposes named, if it sees fit to do so. A bank may be organized with or without the authority to issue currency. It may be authorized to receive deposits in only a limited way. Speaking generally, a bank is a moneyed institution to facilitate the borrowing, lending and caring for money. But whether [211]*211technically banks, or not, these organizations may serve the governmental purposes declared by Congress in their creation. Furthermore, these institutions are organized to serve as a market for United States bonds. Not. less than 5% of the capital of the Federal Land Banks, for which stock is outstanding to Farm Loan Associations, is required to be invested in-United States bonds. Both kinds of banks are empowered to buy and sell United States bonds.
In First National Bank v. Union Trust Co., supra, this court sustained the power of Congress to enable a national bank to transact business, which, by itself considered, might be beyond the power of Congress to authorize. In that case it was held to be within the authority of Congress to permit national banks to exercise, by permission of the-Federal Reserve Board, when not in contravention of local law, the office of trustee, executor, administrator or registrar of stocks or bonds.
We, therefore, Conclude that the creation of these banks, and the grant of authority to. them to act for the Government as depositaries of public moneys and purchasers of Government bonds, brings them within the creative power of Congress although they may be intended, in connection with other privileges and duties, to facilitate the making of loans upon farm security at low rates of interest. This does not destroy the validity of these enactments any more than the general banking powers destroyed the authority of Congress to create the United States Bank, or the authority given to national banks to carry on additional activities, destroyed the authority of Congress to create those institutions.'
In the brief filed upon reargument counsel, for the appellant seem to admit the power of Congress to appropriate money for the direct purposes named, and in that brief they say: “Tax exemption is the real issue sought to be settled here;” " Deciding, as we do, that these institu[212]*212tions have been created by Congress within the exercise of its legitimate authority, we think the power to make the securities here involved tax exempt necessarily follows. This principle was settled in McCulloch v. Maryland, and Osborn v. Bank, supra.
That the Federal Government can, if it sees fit to do so, exempt such securities from taxation, seems obvious upon the clearest principles. But, it is sáid to be an invasion of state authority to extend the "tax exemption so as to restrain the power of the State. Of a similar contention made in McCulloch v. Maryland, Chief Justice Marshall uttered his often quoted statement: “That the power to taxrinvolves the power to destroy; that the power to destroy may defeat and render useless the power to create; that there is . a plain repugnance in conferring on-one government a power to control the constitutional measures of another, which other, with respect to those very measures, is declared to be supreme over that which exerts the control, aré propositions not to be denied.” 4 Wheat. 431.
The same principle has been recognized in the National Bank Cases declaring the''power of the States to tax the property and franchises of national 'banks only to the extent authorized by the laws of Congress. Owensboro National Bank v. Owensboro, 173 U. S. 664, involved the validity of a franchise tax in Kentucky on national banks. In that case this court declared (pp. 668, 669) that the States were wholly without power to levy any tax directly or indirectly upon national banks, their property, assets or franchises, except so far as the permissive legislation of Congress -allowed such taxation; and the court declared that the right granted tó tax the real estate of such banks, and the shares in the names of the shareholders, constituted the extent of the permission given by Congress, and any tax beyond these was declared to be void. <. .
[213]*213In Farmers & Mechanics Savings Bank v. Minnesota, 232 U. S. 516, this court held that a State may not tax bonds issued by the municipality of a territory; that to tax such bonds as property in the hands bf the holder is, in the last analysis* aD imposition upon the right of a municipality to issue them.
The exercise of such taxing power by the States might be so used as to hamper and destroy the exercise of authority . conferred by Congress, -and this justifies the ¿exemption.. If the States can tax these bonds they may destroy the means provided fon obtaining the necessary funds for the future operation of the banks. With the wisdom and policy of this legislation we have nothing to do. Ours is only the function of ascertaining whether Congress in the creation of the banks, and in exempting these, securities Jrom taxation, federal and state, has acted within the limits of its constitutional authority. For the reasons stated, we think the contention of the Government, and of the appellees, that these banks are constitutionally organized and. the securities here involved legally exempted from taxation, must, be sustained.
It follows that the decréa bf the District Court is
Affirmed.
Mr. Justice Brandéis tobk no part in the consideration or decision of this case.
