Back of this suit stands a valid and legal contract, upon which it is based. Mayor &c. of Washington v. Faver, 155 Ga. 680 (117 S. E. 653); Faver v. Mayor &c. of Washington, 159 Ga. 568 (126 S. E. 464). The allegations of the petition as amended show a cause of action which is not barred by the statute of limitations, and the court did not err in overruling the general and special demurrers to the petition. Judgment affirmed.
