The question involved: Did Watauga County contract a debt of $25,000 within the meaning of Article V, section 4, of the Constitution of the State of North Carolina during the fiscal year ending 30 June, 1939? We think so, under the facts and circumstances of this case.

An interpretation of certain sections of law will decide the issue involved. One question is from the N. C. Constitution, Art. Y, sec. 4, as, amended. This section, in part, is as follows: “And counties and municipalities shall not contract debts during any fiscal year, to an amount exceeding two-thirds of the amount by which the outstanding indebtedness of the particular county or municipality shall have been reduced during the next preceding fiscal year, unless the subject be submitted to a vote of the people of the particular county or municipality.”'

N. C. Code, 1935 (Michie), sec. 5683, provides: “Loans by State Board from State Literary Fund. The State Board of Education under such rules and regulations as it may deem advisable, not inconsistent with the provisions of this article, may make loans from the State Literary Fund to the county hoard of education of any county for the building and improving of public schoolhouses or dormitories for rural high schools and teacherages and buildings for county farm-life schools in such county; but no warrant for the expenditure of money for such purposes shall be issued by the auditor except upon the order of the-State Superintendent of Public Instruction, with the approval of the State Board of Education.”

*93 Section 5684 provides: “Terms of Loans. Loans made under tbe provisions of this article shall be payable in ten installments, shall bear interest at four per centum, payable annually, and shall be evidenced by the note of the county hoard of education, executed by the chairman and secretary thereof, and deposited with the State Treasurer. The first installment of such loan, together with the interest on the whole amount then due, shall be paid by the county board of education on the 10th day of February, after the 10th day of August subsequent to the making of such loan and the remaining installments, together with the interest, shall be paid, one each year, on the 10th day of February of each subsequent year till all shall have been paid.”

Section 2492 (20) provides: “Obligations of units must be certified, by Commission. No bonds or notes or other obligations of any unit hereafter issued shall be valid unless on the face or reverse thereof there be a certificate signed by the secretary of the Commission or an assistant designated by him either (a) that the issuance of the same has been approved, under the provisions of the Local Government Act, or (b) that the bond or note is not required by law to be approved by the Commission. Such certificate shall be conclusive evidence that the requirements of this act as to approval by the Commission, advertisement and sale have been observed, and shall also be conclusive evidence that the requirements of sections 2492 (21) and 2492 (22) have been complied with.”

If the debt was contracted during the fiscal year ending 30 June, 1939, the loan would come under Art. V, sec. 4, of the N. C. Constitution, supra, and would be a valid contract. The contention of defendant relates to detail which was not a condition precedent to be effective during the fiscal year.

In Belk’s Department Store v. Ins. Co., 208 N. C., 267 (270), speaking to the subject as to what constitutes a contract, it is said: “In Overall Co. v. Holmes, 186 N. C., 428 (431-2), a contract, citing numerous authorities, is defined as follows: ‘A contract is “an agreement, upon sufficient consideration, to do or not to do a particular thing.” 2 Blackstone Com., p. 442. There is no contract unless the parties assent to the same thing in the same sense. A contract is the agreement of two minds —the coming together of two minds on a thing done or to be done. “A contract, express or implied, executed or executory, results from the concurrence of minds of two or more persons, and its legal consequences are not dependent upon the impressions or understandings of one alone of the parties to it. It is not what either thinks, but what both agree.” ’ Jernigan v. Ins. Co., 202 N. C., 677 (679).”

In Shubert Theatrical Co. v. Rath, 271 Fed., 827 (834), we find: “Authorization to communicate acceptance by mail is implied . . . *94 where the post is used to make the offer and says nothing as to how the answer is to be sent.”

In Rucker v. Sanders, 182 N. C., 607 (608), we find: “The offer to sell . . . was made by mail, which carried with it an implied invitation, nothing else appearing, to accept or reject the offer in like manner, that is by mail.” Patrick v. Bowman, 149 U. S., 411; 6 R. C. L., 611; Farmers' Produce Co. v. McAlester Storage Co., 48 Okl., 488; Shaw v. Ingram-Day Lumber Co., 152 Ky., 329.

In Durant v. Powell, 215 N. C., 628 (633), it is said: “ ‘An offer may invite an acceptance to be made by merely an aifirmative answer, or by performing or refraining from performing a specified act, or may contain a choice of terms from which the offeree is given the power to make a selection in his acceptance.’ Restatement of Law-Contracts, Amer. Law Inst., Vol. 1, sec. 29.”

In Rucker v. Sanders, supra, at p. 609, it is said: “And if the contract be binding as to one of the parties, it is binding as to both. The defendant’s offer was accepted absolutely, without condition, and this resulted in an executory contract, with mutuality of obligation and remedy. Howell v. Pate, 181 N. C., 117, and cases there cited.”

In Sides v. Tidwell, 216 N. C., 480 (483), is the following: “In the making of a contract it is essential that the parties assent to the same thing in the same sense, and their minds must meet as to all the terms,” citing many authorities.

In N. C. Code, sec. 2492 (20), supra, it will be noted that this section makes no mention of the time element such as is contemplated by Article Y, section 4, as amended, of the Constitution. The intention of the Legislature seems to be clearly set out in the last sentence of said section, in that the secretary of the Local Government Commission certify by signature, to the effect that such bonds or notes were in proper order. His approval of the bond issue was made before the bonds were ever executed. This certificate by signature was clearly not meant to be a part of the contract itself, and therefore would not be required to be signed during the fiscal year as set out by the Constitution. It is not denied that approval of the secretary of Local Government Commission is made a necessity, but the statute does not say this approval is to be made within the fiscal year as required by the Constitution, Art. Y, sec. 4. That statute law requiring certain things to be done is made a part of the contract is true, but in some cases we still find that the above section does not set down the requirement that the approval of the secretary of the Local Government Commission is a condition precedent to the contracting of the debt as set out in the Constitution. We think the contract was made during the fiscal year beginning 1 July, 1938, and ending 30 June, 1939. There was no condition precedent that the *95 approval of tbe secretary of tbe Local Government [Commission] sbonld be made during tbe fiscal year above set forth. Tbe loan was approved by tbe defendant, State Board of Education, on 21 June, 1939, during tbe fiscal year in wbicb tbe money could be borrowed under tbe Constitution, Art. V, sec. 4. Tbe detail complained of could be completed after 30 June, 1939, but tbe contract was executed, and a binding one, when received by defendant on 30 June, 1939.

Tbe department of tbe Attorney-General is watchful and efficient and was correct in seeing that tbe State loaned no money on an invalid obligation.

We think tbe judgment of tbe court below should be

Affirmed.
