authority; and all who deal with a public agent must at their peril 'inquire into his real power to bind his principal.”
In a Georgia case, where officers had caused lands to be sold for the State, the court held that this did not estop the State from afterwards asserting that the lands were not subject to taxation and claiming -them. The court said: “Nothing done by the comptroller general or the sheriff, or the tax officers of the county, or the treasurer of the State, in reference to the fund which went into the State treasury, derived from the sale of the land, or that derived from the taxes collected from year to. year, would have the effect of estopping the State, no one- of its public officers having acted within the scope of his authority when he dealt with the property or the fund.”
The same rule should apply to any governmental agency in the exercise of purely public functions. Herman on Estoppel, §1222; St. Louis v. Gorman, 29 Mo. 593. There is no reason why the unauthorized acts of a levee district should estop it from asserting its rights than that the State should not be es-topped by the unauthorized acts of its officers or agents. The ‘officers of the levee district who assessed and collected the taxes in the name of the district had no authority under the law to sell the lands of the district, and to hold that their unauthorized acts estop the district is to empower them to do indirectly that which they cannot directly do.
We do not intend to hold that the levee district cannot under any circumstances be estopped by unauthorized acts of its officers, for, when things are done by an unauthorized method which are within the power of the corporation to do, the unauthorized acts may be ratified by the corporation acting through those of its officers who have authority to do so. But the ratification, to be effective as an estoppel, must be made by the officers or agents authorized to do those things, as one who was unauthorized to perform the original act would be without authority to ratify the same act done by another. Texarkana v. Friedell, 82 Ark. 531.
The case of Book v. Polk, 81 Ark. 244, which is relied on by counsel for appellees, does not reach to-the point involved here, and is without controlling force. There the court held that where the president of the levee district, who is authorized by statute to sell and convey lands for cash, conveyed land to a purchaser for part cash and part on credit, the conveyance was valid and
