— The proceedings upon which this action is based were commenced before the board of supervisors of San Diego county for the purpose of creating a private road. By a writ of review these proceedings were brought before the superior court and there held to be valid. This appeal is taken from such adjudication.

1. It appears, both by the petition and the order of the board of supervisors laying out the road, that the proceedings were inaugurated for the benefit of one *533 J. F. Wilson, in order that he might secure a way of access to his farm. Wilson is not one of the signers to the petition for the road, and it is insisted that, under section 2692 of the Political Code, one party at least who is directly benefited by the laying out of the road must sign the petition. Such a course certainly would be the better practice, and it is somewhat anomalous that Wilson, the party directly interested, did not indicate his assent to the proceedings by attaching his name to the petition; but we think the proceeding is void for other reasons, and therefore do not find it necessary to give a construction to section 2692 of the Political Code in this regard.

2. As is said in Hill v. Board of Supervisors, 95 Cal. 242 , the mode prescribed by the statute for the laying out of roads is to some extent the measure of the power of the board of supervisors. The board cannot take a step until a petition is filed, which petition in form must be in substantial compliance with the requirements of the statute. But even when the petition is filed some thing more must be done before the board can act. A bond must be filed. Section 2683 of the Political Code declares that a bond must accompany the petition, and it is only when the petition and bond are presented to the board of supervisors that power is vested in it to take affirmative action. A bond in substantial compliance with the statute is as necessary to vest the board with jurisdiction to act as is a petition in substantial compliance with the statute. At the time the petition was presented a bond in the amount of fifty dollars accompanied it, which recited: “The condition of this obligation is such that, whereas James F. Wilson and others have petitioned the board of supervisors of San Diego county, state of California, for a private highway, the probable cost of viewing, laying out,” etc. By its face the bond appears to be given upon a petition for a private road by James F. Wilson and others, and in no way refers to the petition upon which the proceedings in this case were inaugurated. Wilson is not a signer *534 to the petition here involved, and such reference being the only mark of identification found in the bond, we must assume that the bond was intended.to accompany some other petition. We think it wholly void as a bond to support the petition in this case, and in no degree assisted the board of supervisors in securing jurisdiction of the proceeding.

3. Again, as a bond supporting any petition for a private road it was fatally defective. There was no condition in the bond as provided in section 2692 of the Political Code, viz: “ The bondsmen will pay to the person over whose land said road is sought to be opened his necessary costs and disbursements in contesting the opening of such road, in case the petition be not granted and the road finally not opened.” The foregoing is a necessary and essential condition of every bond accompanying a petition for the laying out of a private road. At a very late stage in the progress of the proceedings the defect in the bond in this regard was attempted to be cured by filing an amended bond. We think nothing was gained by such a course. If a valid bond was necessary to give the board jurisdiction to act at all, we do not see how an amended bond could validate previous acts of the board done without jurisdiction. We do not see how a fatally defective bond could be cured by an amendment at this stage of the proceedings any more than a fatally defective petition could be cured at that time.

For the foregoing reasons we think the proceedings of the board in laying out this road were had without jurisdiction, and therefore void.

The judgment is reversed and the cause remanded.
