after stating the case: The answer to the question raised by the demurrer of the individual defendants depends upon whether the bond signed by them is one of strict suretyship, specially limited to the State Highway Commission, and therefore nonassignable, or whether it is a general guaranty of payment, assignable with the transfer of the deposit it was given to secure.
We concur in the view taken by the trial court, that the bond in question partakes of the nature of a general guaranty of payment, and is assignable with the debt it.was given to secure. 2 R. C. L., 593-601; Trust Co. v. Construction Co., 191 N. C., p. 667. For present purposes, it is sufficient to say that a guaranty of payment is an absolute or unconditional promise to pay some particular debt, if not paid by the principal debtor at maturity (Jones v. Ashford, 79 N. C., 173), and it is generally held that such a guaranty is assignable and enforceable by the same persons who are entitled to enforce the principal obligation, which it is given to secure. 28 C. J., 950; 5 C. J., 948; Sykes v. Everett, 167 N. C., p. 608; Bank v. Libbey, 101 Wis., 193; Ellsworth v. Harmon, 101 Ill., 274; Claflin v. Ostrom, 54 N. Y., 581; Stillman v. Northrup, 109 N. Y., 475; Everson v. Gere, 122 N. Y., 290; Lane v. Duchac, 73 Wis., 655; Kimball Co. v. Mellon, 80 Wis., 143.
Speaking of the distinction between a guaranty of payment and a guaranty of collection in Cowan v. Roberts, 134 N. C., 415, Walker, J., delivering the opinion of the Court, said: “A guaranty is a promise to answer for the payment of some debt, or the performance of some duty, in case of the failure of another person who is himself in the first instance liable to such payment or performance. Carpenter v. Wall, 20 N. C., 279. There is a well-defined distinction between a guaranty of payment and a guaranty for the collection of a debt, the former being an absolute promise to pay the debt at maturity, if not paid by the principal debtor, when the guarantee may bring an action at once against the guarantor, and the latter being a promise to pay the debt upon condition that the guarantee diligently prosecuted the principal debtor for the recovery of the debt, without success. Jones v. Ashford, 79 N. C., 172; Jenkins v. Wilkinson, 107 N. C., 707; 22 Am. St., 911.”
It would seem that the conversion of the First National Bank of Snow Hill into the Bank of Greene, viewing the allegations of the complaint in this respect as true, did not destroy or affect the guaranty of the individual defendants so far as their liability had become fixed at the time when the First National Bank of Snow Hill gave up its charter *527under the national law and assumed the status of a State hank under the State law. City Nat. Bank of Poughkeepsie v. Phelps, 86 N. Y., 484; First Soc. M. E. Church v. Brownell, 5 Hun., 464.
It will be observed that in the latter part of the “condition” of the bond, as above set out, the parties themselves undertake to place an interpretation upon its meaning, “it being the purpose and intent of the undersigned, by these presents, to bind ourselves, and each of them jointly and severally to the payment of any funds now on deposit, or that may hereafter be put on deposit in the First National Bank of Snow Hill, North Carolina, by the North Carolina Highway Commission,” which would seem to import without doubt a general guaranty of payment, and it is the general rule of construction that where, from the language employed in a contract, a question of doubtful meaning arises, and it appears that the parties themselves have interpreted their contract, practically or otherwise, the courts will ordinarily follow such interpretation, for it is to be presumed that the parties to a contract know best what was meant by its terms, and are least liable to be mistaken as to its purpose and intent. Wearn v. R. R., 191 N. C., p. 580; Lewis v. Nunn, 180 N. C., 164; Guy v. Bullard, 178 N. C., 228; Plumbing Co. v. Hall, 136 N. C., 530; 2 Williston on Contracts, sec. 623; 13 C. J., 546; 6 R. C. L., 852.
The liability of the individual defendants., we apprehend, is not affected by the fact that the bond in suit was not signed by the principal, though this question was not debated on the argument, nor is it discussed in the briefs. Clark v. Bank of Hennessey, 14 Okla., 572; 2 Ann. Cas., 219, and note. See, also, Notes: 22 Ann. Cas., 1014; Ann. Cas. 1917 C, 1073.
We forego any further discussion of the case, as it is here on demurrer, and the defendants have not yet answered. They may plead, for aught we know, that the bond in suit was intended to be personal to the State Highway Commission, and ask for a reformation in its terms. Stillman v. Northrup, 109 N. Y., 473. Furthermore, when the language of an instrument is ambiguous and does not furnish conclusive evidence of its meaning, the courts are permitted to look at all the circumstances of the ease and arrive at the intention of the parties from these sources of information. Evansville Nat. Bank v. Kaufmann, 93 N. Y., 273. But when a case is presented on demurrer, we are required by the statute, C. S., 535, to construe the complaint liberally, “with a view to substantial justice between the parties,” and in enforcing this provision we have adopted the rule “that if in any portion of it .or to any extent it presents facts sufficient to constitute a cause of action, or if facts sufficient for that purpose can be fairly gathered from it, the pleading will stand, however inartificially it may have been drawn or however uncertain, *528defective and redundant may be its statements, for, contrary to tbe common-law rule, every reasonable intendment and presumption must be made in favor of the pleader.” Dixon v. Green, 178 N. C., p. 209. See, also, Lee v. Thornton, 171 N. C., 209; Renn v. R. R, 170 N. C., 128; Brewer v. Wynne, 154 N. C., 467; Blackmore v. Winders, 144 N. C., 212.
It follows, therefore, from what is said above, tbat tbe demurrer interposed by tbe appealing defendants was properly overruled. Mudge v. Varner, 146 N. C., 147; Voorhees v. Porter, 134 N. C., 591; Jenkins v. Wilkinson, 107 N. C., 707.
