Tbe exception raises tbe question whether tbe instrument purporting to be a contract between tbe county of Johnston and tbe State Highway Commission was ultra vires', or entered into without authority of law; and the answer to this question involves the alleged legal right of the county to make the proposed loan and of the commission to obligate itself to the repayment thereof as the contract provides.

The act creating the existing highway commission and making provision for a State system of dependable roads went into effect on 3 March, 1921, authorizing the continuance of the former commission, however, until the commission thereby created should be formally organized. Public Laws 1921, ch. 2; Public Laws 1919, eh. 189. Soon thereafter the provisions of section 14 were sustained on appeal from a judgment rendered in the Superior Court of Harnett County. In that case it was alleged that on 20 May, 1921, the board of commissioners had entered into a contract with the State Highway Commission, in accordance with section 14, for the advancement of funds to construct a part of the highway system through the county. This Court, upholding the contract, said in substance that a county primarily is required to construct and! maintain its roads and bridges, and that as the board of commissioners was specially authorized by section 14 to contract with the highway commission in reference to the construction of the road, it was the duty of the board, so far as it was legally empowered, to provide the funds necessary for such purpose. R. R. v. McArtan, 185 N. C., 201.

In Lassiter v. Comrs., 188 N. C., 379, the act of 1921, ch. 2, was presented in another phase. There it appeared that as between two routes proposed for a part of the State highway system extending from Raleigh to Wendell, the State Highway Commission had adopted the Milburnie, or upper road, on condition that the board of commissioners of Wake County should contribute the sum"of $41,500 as a proper liability and as a proportion of the cost of construction and repair to be borne by the county. It was objected that without a vote of the people the commissioners had no legal right to make the contribution, but the Court held otherwise, Chief Justice Hoke saying: “So all- . pervading and insistent is the power of county commissioners on the question of public roads that, although special legislation may disclose a purpose to supervise and control the matter of roads by other boards, as the township system, unless clearly forbidden by such legislation, the county commissioners could lend proper aid to this effort by appropriating general county moneys for the purpose. Bunch v. Comrs., 159 N. C., p. 335. And it has also been uniformly held that in the exercise of these powers the construction and repair of the public roads *55are a necessary expense not requiring tbe approval o£ a popular vote. Woodall v. Highway Commission, 176 N. C., 377; Davis v. Lenoir, 178 N. C., 668; Hargrave v. Comrs., 168 N. C., 626; Murphy v. Webb, 156 N. C., 402. It is urged against tbe exercise of such power in tbe present instance tbat wben tbe Milburnie Road is taken over by tbe bigbway commission, sucb commission is given full control, and it is tben no longer a county road; but, as shown in tbe evidence, tbis was a public road, a part of tbe county system, and for tbe repair and upkeep of wbicb tbe county was liable. Unless and until it is taken over by tbe State commission it constitutes a county charge. And we see no reáson why, in tbe exercise of their power concerning it, tbe county commissioners may not provide by contract a way for tbe continued and reliable upkeep by tbe State commission, and thus relieve tbe county of tbe incidental burdens. True, we would be slow to bold that county commissioners could make an arrangement with some nonofficial board by wbicb they would undertake to absolve themselves from their governmental duties in tbe matter, but tbis present arrangement is with a governmental body also under tbe control of tbe State and wbicb, by tbe acts of its creation, is given full power to take over roads and stipulate for tbe terms in wbicb they will do it.”

In these cases it is held in purport and effect, if not in express words, tbat where there is no legislation providing otherwise, tbe boards of county commissioners are charged with responsibility for tbe construction and maintenance of tbe public roads in their respective counties; tbat tbe cost of sucb construction and upkeep is a necessary expense; tbat these governmental agencies, tbe boards of county commissioners and tbe State Highway Commission, are vested with power to enter into contracts and agreements for tbe construction of roads forming a part of tbe State bigbway system, and tbat tbe purpose of tbe act of 1921, cb. 2, is to encourage cooperation between tbe bigbway commission and tbe county authorities. In tbe first of these cases (R. R. v. McArtan) tbe board of commissioners, after making a contract with tbe commission, found it necessary to borrow $100,000, and to tbis end issued county securities and levied a tax to provide for their payment,- and tbe court not only approved tbe contract, but declined to restrain tbe collection of tbe tax; and in tbe second (Lassiter v. Comrs.), tbe amount appropriated for building tbe road on tbe accepted route was treated as a, proper liability of tbe county. If tbe contracts set out in these cases were enforceable, we see no sufficient or satisfactory reason why Johnston County, pursuing tbe same policy and relying on tbe same principle, could not enter into a valid contract with tbe bigbway commission for making tbe proposed loan.

*56But against the alleged right of the county to advance the money it is urged on behalf of the plaintiff that the agreement for “fair reimbursement” cannot be enforced against the highway commission, because the county is to be paid by the allocation of money to be raised by the sale of bonds hereafter to be authorized, or by the appropriation of other road construction funds. Accepting as the definition of a contract an agreement enforceable at law made between two or more persons by which rights are acquired by one or more to acts or forbearance on the part of the other or others, we are confronted with the direct question whether the terms of the obligation assumed by the highway commission to reimburse the county are such as will avoid the contract.

As we understand, no point is made as to the right to contract that a debt may be paid out of a particular fund. Evans v. Freeman, 142 N. C., 61; Typewriter Co. v. Hardware Co., 143 N. C., 97; Basnight v. Jobbing Co., 148 N. C., 350, 357. The objection stressed is the uncertainty of the fund, or the commission’s agreement to create an indebtedness in excess of the funds appropriated to its use. It is contended by the defendants that the force of this objection may depend upon the scope and efficacy of the contract interpreted in the light of the principle which underlies and the purpose which pervades the act by which the highway commission was created; that the act, notwithstanding its diverse subdivisions, is to be regarded as a unified whole; that its chief purpose was to enable the commission as an agency of the State to construct, take control of, and maintain approximately 5,500 miles of dependable highways and thereby to establish a system for the entire State, work on the various links to be of such character as would lead to hard-surfaced construction as rapidly as money, labor, and material should permit; and that it was thought that the work would cover an indefinite period and that the funds necessary for the accomplishment of the ultimate object would be raised from time to time as the work progressed. To the achievement of this end, it is contended, the act contemplates cooperation, unity of purpose, and, as far as practicable, unity of action between the highway commission and the various counties of the State. Public Laws 1921, ch. 2, secs. 2, 3, 10(b), 10 (i), 14. Upon this theory the defendants assert that the legislative intent to carry on the work until the highways outlined in the act of 1921 are completed indicates a purpose to provide the necessary funds, from year to year, by issuing bonds and in other ways; that the agreement on the part of the highway commission to pay back the money advanced by the county should be construed in the light of this general legislative policy; and that the principle usually applicable to a promise to make payment out of funds not presently available is not controlling in the present instance.

*57We need not now determine whether this position is fundamentally sound, for without regard to it the contract, in our opinion,* may be sustained. The allocation of funds to be derived from the sale of bonds hereafter to be issued is not the only means provided for satisfaction of the loan. By the terms of the contract, “other road construction funds” may be applied in liquidation. In the answer of the board of commissioners it is said that continuing funds now authorized by legislative provision will entitle Johnston County to an annual road construction fund of about $60,000, which may lawfully be applied in repayment of the money advanced. An allegation substantially to this effect appears in the affidavit made by the chairman of the highway commission. If from this fund thére be deducted an amount sufficient to pay the interest on the authorized bonds and to provide a sinking fund for their retirement in addition to the cost of maintenance, the remainder, it is admitted, may be applied on the loan. The sum annually provided in this way is limited, but -it may be thus applied, in the words of the contract, “to the extent that it may be sufficient therefor.” This in itself is such valuable consideration as will support the contract: a promise by the county to advance the money and a promise by the highway commission to make payment out of funds presently available “to the extent of their sufficiency” for such purpose. No question is made as to the adequacy of the consideration, for the law does not require that the consideration and the thing to be done shall be in "exact proportion as to values. “So long as it is something of real value in the eye of the law, whether or not the consideration is adequate to the promise, is generally immaterial in the absence of fraud. The slightest consideration is sufficient to support the most dnerous obligation; the inadequacy, as has been well said, is for the parties to consider at the time of making the agreement, and not for the court when it is sought to be enforced.” 13 C. J., 365; Exum v. Lynch, 188 N. C., 392, 396.

With knowledge not only of its primary responsibility for the construction and upkeep of its public roads, but of the liability of each party to the proposed contract, the board of commissioners of Johnston County, for the purpose of building a part of the highway system, has. agreed to advance to the highway commission a fixed sum which is to be repaid by the commission out of designated funds, a part of which is now available; and upon the facts appearing in the record we find no objection that prevents the parties from making and receiving the loan in accordance with their agreement.

The judgment declaring the contract void and continuing the restraining order to the final hearing is, therefore,

Reversed.
