This case involves the question whether the two checks or orders upon which the tax was imposed are exempt from state taxation under Rev. Stat. § 3701, U. S. Comp. Stat. 1901, p. 2480, declaring that 'all stocks, bonds, Treasury notes, and other obligations of the United States, shall be exempt from taxation by or under state or municipal or local authority.' The basis of this exemption is the fact that a tax upon the obligations of the United States is virtually a tax upon the credit of the government, and upon its power to raise money for the purpose of carrying on its civil and military operations. The efficiency of the government service cannot be impaired by a taxation of the agencies which it employs for such service, and, as one of the most valuable and best known of these agencise is the borrowing of money, a tax which diminishes in the slightest degree the value of the obligations issued by the government for that purpose impairs pro tanto their market value.

The inability of the states to tax the official agencies of the Federal government, whether in the form of banks chartered under its authority, or of obligations issued by it as a means of providing a revenue, or for the payment of its debts, was applied in M'Culloch v. Maryland, 4 Wheat. 316, 4 L. ed. 579, to a stamp tax upon notes of the United States bank; in Weston v. Charleston, 2 Pet. 449, 7 L. ed. 481, and in New York ex rel. Bank of Commerce v. Tax Comrs. 2 Black, 620, 17 L. ed. 451, to stock issued for loans made to the government of the United States; and in the Bank Tax Case (New York ex rel. Bank of Commonwealth v. Tax & A. Comrs.) 2 Wall. 200, 17 L. ed. 793, to a tax laid on banks on a valuation equal to the amount of their capital stock, when their property consisted of stocks of the Federal government; in The Banks v. New York (New York ex rel. Bank of N. Y. Nat. Bkg. Asso. v. Connelly) 7 Wall. 16, 19 L. ed. 57, to certificates of indebtedness of the United States, issued to the creditors of the government for supplies furnished in carrying on the Civil War; in Bank of New York v. New York County (New York ex rel. Bank of New York v. New York County) 7 Wall. 26, 19 L. ed. 60, to notes of the United States intended to circulate as money; and in Van Brocklin v. Tennessee (Van Brocklin v. Anderson) 117 U. S. 151, 29 L. ed. 845, 6 Sup. Ct. Rep. 670, to land purchased by the United States, for the amount of a direct tax laid thereon.

The principle, however, upon which this exemption is claimed, does not apply to obligations such as checks and warrants, intended for immediate use, and designed merely to stand in the place of money until presented at the Treasury, and the money actually drawn thereon. In such case the tax is virtually a tax upon the money which may be drawn immediately upon presentation of the checks. As was said by Mr. Justice Miller in First Nat. Bank v. Kentucky, 9 Wall. 353, 362, 19 L. ed. 701, 703: 'That limitation [upon the power to tax] is, that the agencies of the Federal government are only exempted from state legislation, so far as that legislation may interfere with, or impair, their efficiency in performing the functions by which they are designed to serve that government.'

In Union P. R. Co. v. Peniston, 18 Wall. 5, 21 L. ed. 787, it was insisted by the plaintiff in error that the property of the Union Pacific Railroad Company was exempt from state taxation by virtue of the incorporation of the company by the United States, as a means for the performance of certain public duties of the government, enjoined and authorized by the Constitution. It was said, however, by Mr. Justice Strong, in delivering the opinion of the court, that no constitutional implications prohibited a state tax upon the property of an agent of the government merely because it is the property of such agent, but 'that the agencies of the Federal government are uncontrollable by state legislation, so far as it may interfere with, or impair, their efficiency in performing the functions by which they are designed to serve that government. It is, therefore, manifest that exemption of Federal agencies from state taxation is dependent, not upon the nature of the agents, or upon the mode of their constitution, or upon the fact that they are agents, but upon the effect of the tax; that is, upon the question whether the tax does, in truth, deprive them of power to serve the government as they were intended to serve it, or does hinder the efficient exercise of their power. A tax upon their property has no such necessary effect. It leaves them free to discharge the duties they have undertaken to perform. A tax upon their operations is a direct obstruction to the exercise of Federal powers.'

Had the government, in the absence of money for the immediate payment of interest upon its bonds, issued new obligations for the payment of this interest at a future day, it might well be claimed that these were not taxable, as the taxation of such notes would, to the extent of the tax, impair their value and negotiability in the hands of the holder. This was practically the case in The Banks v. New York (New York ex rel. Bank of N. Y. Nat. Bkg. Asso. v. Connelly) 7 Wall. 16, 19 L. ed. 57, where certificates were issued at a time when the government had no money to pay its obligations, and made use of its credit to obtain further time. But where checks are issued payable immediately, they merely stand in the place of coin, which may be immediately drawn thereon. As observed by the court below, the checks were, for all practical purposes, the money itself. People v. Stockton & V. R. Co. 45 Cal. 306, 313; Metropolitan Nat. Bank v. Sirret, 97 N. Y. 320, 325; Re Staten Island Rapid Transit R. Co. 38 Hun, 382, 101 N. Y. 636. A check may be given in evidence under the money counts. Wells v. Brigham, 6 Cush. 6, 52 Am. Dec. 750; Cruger v. Armstrong, 3 Johns. Cas. 5, 2 Am. Dec. 126.

While Congress has not amended Rev. Stat. § 3701, U. S. Comp. Stat. 1901, p. 2480, upon which plaintiff relies in this case, it did, by act approved August 13, 1894 (28 Stat. at L. 278, chap. 281, U. S. Comp. Stat. 1901, p. 2398), declare 'that circulating notes of national banking associations and United States legal tender notes, and other notes and certificates of the United States, payable on demand, and circulating, or intended to circulate, as currency, . . . shall be subject to [state] taxation as money on hand or on deposit.'

Although the checks in question were not intended to circulate as money, and therefore do not fall within the letter of the statute, the reasons that apply to that class of obligations we think apply with equal force to checks intended for immdiate payment, though not intended to circulate as money. While the checks are obligations of the United States, and within the letter of § 3701, they are not within its spirit, and are proper subjects of taxation.

Had the plaintiff drawn the money immediately upon these checks, it would have become at once a part of the general property of the bank; and the fact that the money had been derived from the United States, and paid to the bank as interest on its obligations, would not have prevented its becoming part of the general property of the bank, and subject to state taxation.
