GRAY, C.

Appeal from judgment on judgment-roll with out a bill of exceptions.

The plaintiffs furnished material in the construction of a building, and, three hundred and fifty dollars and fifteen cents of the contract price thereof remaining unpaid, they brought this action on the contractor’s bond given in pursuance of section 1203 of the Code of Civil Procedure, and obtained judgment for that sum. Appellants are the sureties on said bond.

1. The obligation sued on was not a mere offer of guaranty, *668 depending for its binding force upon a notice of acceptance, but it was a contractor’s bond conforming in all essential respects to the provisions of said section 1203 of the Code of Civil Procedure. It is immaterial whether the liability of appellants was that of sureties or guarantors; suit could be maintained, against them immediately on default of the principal and without demand or notice. Said section provides: “Said bond shall by its terms be made to inure to the benefit of any and all persons who perform labor for or furnish materials to the contractor, or any person acting for him or by his authority; and any such person shall have an action to recover on said bond against the principal or sureties, or either of them, for the value of such labor or materials or both.” No notice is required by this statute. Nor, in the absence of a contract to that effect, is a notice ever required to fix the liability of either a surety or guarantor. (Treweek v. Howard, 105 Cal. 441; Coburn v. Brooks, 78 Cal. 443; Civ. Code, sec. 2807.)

2. Said section 1203 is not unconstitutional. It does not contravene the provisions of section 24, article IV, of the constitution, requiring that every act shall embrace but one subject, which subject shall be expressed in its title. The title to the section is “an act to add a new section to the Code of Civil Procedure of the state of California, to be numbered section 1203, relating to liens of mechanics and others.” The new section is the last of a chapter in the code relating to mechanics’ liens, and in terms it refers to mechanics’ liens and provides a security for claims in addition to such liens. Under the liberal construction of the said provision of the constitution heretofore adopted the title of the act in question must be held to be sufficient. (Ex parte Liddell, 93 Cal. 638; People v. Superior Court, 100 Cal. 120; Hellman v. Shoulters, 114 Cal. 150; San Francisco etc. R. R. Co. v. State Board, 60 Cal. 30.)

Neither is said section 1203 of the Code of Civil Procedure in conflict with any of those provisions of the constitution directed against class legislation and special laws. This section, which was added to the code in 1893, and the previous section of said code bearing the same number and similar in its provisions, which was enacted in 1885 and repealed in 1887, have been under consideration by this court several times and. *669 their constitutionality has not been questioned until now, so far as we are advised. (Mangrum v. Truesdale, 128 Cal. 145; Kiessig v. Allspaugh, 91 Cal. 236; 99 Cal. 453.) No case is cited in which this section or any similar provision has been held unconstitutional. And we think its validity may be upheld on the same reasoning that upholds other sections of the mechanics’ lien law. A similar statute has been held constitutional and free from the objection that it was class legislation by the supreme court of Tennessee. (Cole Mfg. Co. v. Falls, 90 Tenn. 466.)

3. The requirement of section 1057 of the Code of Civil Procedure, that the sureties shall justify by affidavit accompanying the bond is intended solely for the protection of obligees; and it does not lie in the mouth of the sureties to object to the sufficiency of the bond because of their failure to comply with this provision of the law. (People v. Shirley, 18 Cal. 121; Moffat v. Greenwalt, 90 Cal. 368.)

4. The amended complaint is sufficient as against the demurrer interposed to it. It was not necessary to set out in detail the contract between the owner and the contractor. It was sufficient in that connection to set out facts showing, as the amended complaint does, that plaintiff had, pursuant to his contract, furnished materials that were used in the building in pursuance of the contract with the owner. From the fact that the materials were furnished to be used and were used by the contractor in the construction of the house it will be presumed that they were so furnished and used in pursuance of the contract with the owner. Against a general demurrer the allegations of the complaint on this point are certainly sufficient, and there is no special demurrer for uncertainty in this respect.

5. Section 1203 of the Code of Civil Procedure provides that anyone furnishing material may have an action for the value thereof, and the point is made that the value is not alleged in the complaint nor found by the court. The contract price of the materials is alleged and found, and there is no demurrer for uncertainty in the complaint as to value. The complaint and findings must therefore be held sufficient in this respect also. (Bringham v. Knox, 127 Cal. 40.)

The judgment should be affirmed.

*670 Smith, C., and Haynes, C., concurred.

For the reasons given in the foregoing opinion the judgment is affirmed..
