property may be taken by the state, he must be given notice of the proceedings which may terminate in the taking, and be given an opportunity to be heard. It means further that the notice shall be a real and reasonable one, and the hearing, such as is ordinarily, or at least reasonably, given in similar cases (Beck v. Ransome-Crummey Co., 42 Cal.App. 74 [184 P. 431]). Particularly applicable here is the statement found in People v. Broad,'216 Cal. 1 [12 P.2d 941], where this court said . . the essential validity of the law was to be tested not by what has been done under it, but what may by its authority be done; and where a statute makes no provision for hearing or notice, either actual or constructive, such defect is not supplied by the voluntary adoption by public officers of rules covering the situation.” In Roller v. Holly, 176 U.S. 398, 409 [20 S.Ct. 410, 44 L.Ed. 520], it-was said “That a man is entitled to some notice before he can be deprived of his liberty or property, is an axiom of the law to which no citation of authority would give additional weight; but upon the question of the length of such notice there is a singular dearth of judicial decision. It is manifest that the requirement of notice would be of no value whatever, unless such notice were reasonable and adequate for the purpose (Davidson v. New Orleans, 96 U.S. 97 [24 L.Ed. 616] ; Hagar v. Reclamation District, 111 U.S. 701-712 [4 S.Ct. 663, 28 L.Ed. 569]).” In that case, it was held (413) that “Without undertaking to determine what is a reasonable notice to nonresidents, we are of opinion, under the circumstances of this ease, and considering the distance between the place of service and the place of return, that five days was not. a reasonable notice, or due process of law. ...” The Roller case was followed in Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306, 314 [70 S.Ct. 652, 94 L.Ed. 865], where it was said “An elementary and fundamental requirement of due process in any proceeding which is to be accorded finality is notice reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections, Milliken v. Meyer, 311 U.S. 457 [61 S.Ct. 339, 85 L.Ed. 278, 132 A.L.R. 1357] ; Grannis v. Ordean, 234 U.S. 385 [34 S.Ct. 779, 58 L.Ed. 1363] ; Priest v. Las Vegas, 232 U.S. 604 [34 S.Ct. 443, 58 L.Ed. 751] ; Roller v. Holly, 176 U.S. 398 [20 S.Ct. 410, 44 L.Ed. 520], The notice must be of such nature as reasonably to convey the required information, Grannis v. Ordean, supra, and it must afford a
