95 U.S. 644 (____)
NEW ORLEANS
v.
CLARK.
Supreme Court of United States.

*650 Submitted on printed arguments for the Jefferson City Gas-light Company by Mr. Thomas J. Semmes and Mr. Robert Mott; for Clark, by Mr. Samuel Shellabarger and Mr. Jeremiah M. Wilson; and for the city of New Orleans, by Mr. Philip Phillips.
MR. JUSTICE FIELD delivered the opinion of the court.
This was an action upon several coupons for interest annexed to bonds issued by the late city of Carrollton, in Louisiana, to the Jefferson City Gas-light Company, a corporation created under the laws of that State, for laying gas-pipes through certain streets of the city, and introducing gas for the use of its citizens. The bonds were indorsed by the president of the company, with its guaranty, for the payment of their principal and interest. His authority to make this guaranty, so far as it relates to the interest, was denied by the company; but the Circuit Court held that the admissions and evidence in the case showed a prima facie case of liability.
The bonds were issued pursuant to an ordinance of the city, which provided for the payment of the interest thereon, but made no provision for the payment of the principal; and for this omission, and because they were issued in aid of a private corporation, their validity was questioned by the city of New Orleans, upon which the liabilities of Carrollton were cast upon its annexation to that city; and as it was contended in answer to this position that the legislature had subsequently, *651 in the act of annexation, legalized the issue, the power of the legislature to do this was denied, but the Circuit Court held that the legislature possessed the power; and the city of New Orleans was adjudged bound to pay the bonds.
The record shows that the bonds were issued after the work had been done for which the contract was made and the gas had been introduced into the city, and that they were transferred to the plaintiff for a valuable consideration.
Two questions are presented for our determination: 
1st, Whether the Jefferson City Gas-light Company is liable on the guaranty made by its president for the interest on the bonds; and,
2d, Whether it was competent for the legislature of Louisiana to legalize the issue of the bonds, if for any cause they were originally invalid, or, more properly, to compel their payment by the city of New Orleans.
1. The ordinance which authorized the contract with the company, and the issue of the bonds of the city, in terms provided that the company should "guarantee the said bonds and assume the payment of the principal thereof at maturity." Their delivery to the company was made dependent upon this condition; but as the provision mentioned that the company was to assume payment of the principal, after specifying that it was to guarantee the bonds, it is argued that the guaranty of the principal only was intended. This is not, however, a just inference from the language. The guaranty of the bonds embraced both the principal and the interest. The payment of bonds, without other designation, always implies a payment of the principal sum and its incident; and a guaranty in similar terms covers both. The ordinance contemplated two undertakings by the company,  one to the bondholder, and one to the city. The guaranty was to be for the security of the bondholder; it was to be an undertaking to answer for the city's liability, and to be collateral to it. The other undertaking was to be for the security of the city, by placing the company under obligation to provide for the payment of the principal of the bonds at their maturity, an obligation which otherwise would not have existed.
The contract embraced the stipulations contained in the ordinance, *652 and the indorsement of the guaranty of the company by its president on the bonds was a substantial compliance with both. The language used, guaranteeing "the payment of the principal and interest," only declared in terms what would have been implied from a simple guaranty of the bonds. It is not denied that the president was the proper officer to execute whatever guaranty was authorized.
2. The invalidity of the bonds was asserted, as already stated, on two grounds: first, that they were issued in aid of a private corporation; and, second, that the city of Carrollton, in issuing them, created a debt, without providing in the same ordinance the means of paying its principal. The first of these grounds is not one which affects the validity of the bonds. A private corporation, as well as individuals, may be employed by a city in the construction of works needed for the health, comfort, and convenience of its citizens; and, though such works may be used by the corporation for its own gain, yet, as they advance the public good, the corporation may be properly aided in their construction by the city; and for that purpose its obligations may be issued, unless some constitutional or legislative provision stands in the way. The bonds here were not given to the company as a gratuity, but for a valuable consideration; and if the company failed to pay them at maturity, and their payment was made by the city, the gas-works were to become the property of the city.
The second of these grounds is not without force. An act of the legislature of Louisiana, passed in March, 1855, had declared that the constituted authorities of incorporated towns and cities in the State should not thereafter "have power to contract any debt or pecuniary liability, without fully providing in the ordinance creating the debt the means of paying the principal and interest of the debt or contract." This enactment imposed a restriction upon the creation of liabilities by municipal bodies, which could not be disregarded. It was intended to keep their expenditures within their means; and its efficacy in that respect would be entirely dissipated, if debts contracted in violation of it were held legally binding upon the municipalities.
Assuming, then, that the bonds were invalid for the omission *653 stated, they still represented an equitable claim against the city. They were issued for work done in its interest, of a nature which the city required for the convenience of its citizens, and which its charter authorized. It was, therefore, competent for the legislature to interfere and impose the payment of the claim upon the city. The books are full of cases where claims, just in themselves, but which, from some irregularity or omission in the proceedings by which they were created, could not be enforced in the courts of law, have been thus recognized and their payment secured. The power of the legislature to require the payment of a claim for which an equivalent has been received, and from the payment of which the city can only escape on technical grounds, would seem to be clear. Instances will readily occur to every one, where great wrong and injustice would be done if provision could not be made for claims of this character. For example, services of the highest importance and benefit to a city may be rendered in defending it, perhaps, against illegal and extortionate demands; or moneys may be advanced in unexpected emergencies to meet, possibly, the interest on its securities when its means have been suddenly cut off, without the previous legislative or municipal sanction required to give the parties rendering the services or advancing the moneys a legal claim against the city. There would be a great defect in the power of the legislature if it could not in such cases require payment for the services, or a reimbursement of the moneys, and the raising of the necessary means by taxation for that purpose. A very different question would be presented, if the attempt were made to apply the means raised to the payment of claims for which no consideration had been received by the city.
The act of 1874, which annexed Carrollton to New Orleans, provided that all property, rights, and interests of every kind of the former city should be vested in the latter, and that the debts and liabilities of Carrollton, "including the funding and improvement bonds, and the bonds issued to the Jefferson City Gas-light Company, and known as gas bonds," should be assumed and paid by the city of New Orleans; and that city was in terms declared liable therefor. Independently of this legislation, the liabilities of Carrollton would have devolved *654 with its property upon New Orleans on the annexation to that city, so far, at least, that they could be enforced against the inhabitants and property brought by the annexation within its jurisdiction. Broughton v. Pensacola, 93 U.S. 266. Equitable claims which had existed against the dissolved city would continue as before, and be equally subject to legislative recognition and enforcement, or their payment might be required, as in this case, by the act of annexation. The power of taxation which the legislature of a State possesses may be exercised to any extent upon property within its jurisdiction, except as specially restrained by its own or the Federal Constitution; and its power of appropriation of the moneys raised is equally unlimited. It may appropriate them for any purpose which it may regard as calculated to promote the public good. Of the expediency of the taxation or the wisdom of the appropriation it is the sole judge. The power which it may thus exercise over the revenues of the State it may exercise over the revenues of a city, for any purpose connected with its present or past condition, except as such revenues may, by the law creating them, be devoted to special uses; and, in imposing a tax, it may prescribe the municipal purpose to which the moneys raised shall be applied. A city is only a political subdivision of the State, made for the convenient administration of the government. It is an instrumentality, with powers more or less enlarged, according to the requirements of the public, and which may be increased or repealed at the will of the legislature. In directing, therefore, a particular tax by such corporation, and the appropriation of the proceeds to some special municipal purpose, the legislature only exercises a power through its subordinate agent which it could exercise directly; and it does this only in another way when it directs such corporation to assume and pay a particular claim not legally binding for want of some formality in its creation, but for which the corporation has received an equivalent. The People ex rel. Blanding v. Burr, 13 Cal. 343; Town of Guilford v. Supervisors of Chenango County, 18 Barb. (N.Y.) 615; s.c. 13 N.Y. 143.
The Constitution of Louisiana of 1868, which provides that no retroactive law shall be passed, does not forbid such legislation. A law requiring a municipal corporation to pay a demand *655 which is without legal obligation, but which is equitable and just in itself, being founded upon a valuable consideration received by the corporation, is not a retroactive law,  no more so than an appropriation act providing for the payment of a pre-existing claim. The constitutional inhibition does not apply to legislation recognizing or affirming the binding obligation of the State, or of any of its subordinate agencies, with respect to past transactions. It is designed to prevent retrospective legislation injuriously affecting individuals, and thus protect vested rights from invasion.
Judgment affirmed.
