1. Even though a demurrer may have been erroneously overruled, if “ subsequently during the trial the petition was amended so as to cover the defect at which the demurrer pointed, such erroneous ruling .was thereby rendered harmless.” Harris v. Lumpkin, 136 Ga. 47 (2) (70 S. E. 869); Pacific Selling Co. v. Albright-Prior Co., 3 Ga. App. 143 (2) (59 S. E. 468). Assuming but not holding that the defendant, under the writing- sued upon, was. a guarantor rather than surety, and not subject to suit jointly with the principal (Holmes v. Schwab, 141 Ga. 44 (3), 80 S. E. 313; Sims v. Clark, 91 Ga. 302, 18 S. E. 158; Smith v. Adair, 27 Ga. App. 717 (3), 110 S. E. 317; Musgrove v. Luther Pub. Co., 5 Ga. App. 279, 63 S. E. 52), and that the petition was demurrable upon this ground, the amended suit was maintainable upon that theory. If the contract was one of suretyship, the suit likewise was maintainable against the surety alone without joining the alleged principal. Stanfield v. McCommon, 25 Ga. App. 226 (1 a), 228 (102 S. E. 908); Johnson v. Ga. Fertilizer Co., 21 Ga. App. 530 (2, 3) (94 S. E. 850); McMillan v. Heard Natl. Bk., 19 Ga. App. 148 (2), 151 (91 S. E. 235); Small Co. v. Claxton, 1 Ga. App. 83 (57 S. E. 977). Since, therefore, It is immaterial, under the facts of this ease, whether the defendant he treated as a guarantor or-as a surety (Stanfield v. McCommon, supra), it is unnecessary so to determine.
2. The writing in question expresses an absolute, present, and unconditional guaranty, certain as to amount, and general' as to persons except as it is limited to a particular class, to wit, the plaintiff' or *808any other such dealer in bananas as the addressee could induce to form a shipping connection with and extend credit to the principal on the faith of the defendant’s promise to pay. 12 Ruling Case Law, 1061 (§ 10). The instrument, when construed alone or in connection with the circumstances surrounding its execution, does not purport to authorize and limit its authority to a single shipment of bananas aggregating five thousand dollars in amount, but on its face was intended to enable the principal “ to form a connection for buying bananas in carloads,” and necessarily contemplated a course of dealing such as to make it a continuing guaranty. “ Where an absolute promise is made to become responsible for a certain amount, with no limitation as to time, and there is nothing in the circumstances surrounding the execution of the contract to evince a contrary intention, it will be presumed that the promise was to continue until revoked, and the promisor will be held liable to the extent of his guaranty, notwithstanding the principal may have, during the existence of the contract, contracted debts to an amount equal to or greater than the sum named in the guaranty, and paid the same.” Manry v. Waxelbaum, 108 Ga. 14, 21 (33 S. E. 701); 12 R. C. L. 1061 (§ 11). In the instant case the debts which had been previously contracted and paid did not equal b.ut amounted to less than one-half of the amount guaranteed.
Decided July 24, 1922.*8083. Since in such a suit the solvency or insolvency of the principal debtor was immaterial, it was unnecessary for the petition to allege that he was insolvent or unable to pay the account. Penn Tobacco Co. v. Leman, 109 Ga. 428 (2) (34 S. E. 679); 12 R. C. L. 1091. Nor, for the reason stated in the first paragraph above, was it neeessaiw to show that the principal resided outside of the State, beyond the jurisdiction of the court.
4. The evidence authorized the verdict.
