CURTIS, J.
— In this proceeding instituted in 1936 the plaintiff sought a judgment to compel the city of Lakeport and designated officials thereof — namely, the treasurer, tax collector, auditor and assessor — to perform the duties enjoined upon them by law in connection with the enforcement of street assessment liens, and in particular to force a tax sale of certain described real property. By the same action the plaintiff also sought to quiet title against certain individuals claiming the lands involved as the result of purchase at foreclosure sale, and to have it declared that these defendants hold such property subject to the street assessment liens which became delinquent subsequent to the filing of the foreclosure proceedings, and that such liens were not extinguished by the decree of foreclosure. Following the court’s sustaining of the demurrer of the defendant city and its treasurer to the first amended complaint and the plaintiff’s failure to amend its pleading as to them within the time required by law after having received written notice of the court’s ruling, a judgment of dismissal was entered as to these defendants. Accordingly, the action was tried only as against the remaining city officials above mentioned and the individual claimants of the real property. The facts were undisputed. Findings and judgment were entered in favor of the defendants against whom the plaintiff elected to proceed to trial, that the plaintiff take nothing by its action. This appeal is based upon the judgment roll alone, it being the appellant’s contention that the findings justify the relief sought by it. Preliminarily it should be said that the propriety of the trial court’s dismissal of the city of Lakeport and its treasurer from this action is not challenged by either the appellant or the respondents herein, and consequently these originally named defendants are not before this court upon this appeal.
The facts necessary to a determination of the legal ques[256]*256tians presented by this proceeding may be summarized from the findings as follows: In 1925 the city of Lakeport commenced proceedings under the Improvement Act of 1911 (Stats. 1911, p. 730; Deering’s Gen. Laws, 1931, Act 8199) to improve Main Street in said city. To cover the cost of this work it issued bonds under the provisions of the Improvement Bond Act of 1915 (Stats. 1915, p. 1441; Deering’s Gen. Laws, 1931, Act 8209). The plaintiff is the owner of seven of these bonds of the par value of $1,000 each, which bonds matured on the 2nd day of July, 1936. The bonds were duly presented for payment at maturity and thereafter payment to the extent of thirty-eight per cent of the principal and all coupon interest to the date of maturity was made thereon, in pursuance of the terms of a court order as will hereinafter appear.
Assessments levied under the Improvement Bond Act of 1915 upon the property here involved became delinquent for the years 1927 to 1931, inclusive. On May 14, 1931, the city of Lakeport, a municipal corporation, commenced an action to foreclose the liens of these installments, and a decree of foreclosure was made and entered on April 26, 1932, directing the sale of this real property. The sale was held and the defendants Silvers, Godfrey, Morey and Martin each purchased a group of lots, paying the sum of $1.00 for each group and acquiring such property subject to all unpaid installments, interest and penalties under the same proceedings. A certificate of sale and deed were duly issued covering the realty here involved. Assessments levied by the city upon this, property and payable subsequent to the year 1931 have not been paid and are now delinquent. Thereafter and for the period' from 1932 to 1937, inclusive, the city council of the city of Lakeport duly adopted and passed annual resolutions ordering that all assessments remaining due and unpaid on this real property as of the various respective years be collected by foreclosure proceedings, and that the tax collector be credited upon the assessment roll with the amount charged against him on account of such assessments ordered to suit and be relieved of further duties in that regard. No such suits were instituted until subsequent to the filing of the present proceeding and on January 20, 1937, when the city commenced an action to secure judgment for the total [257]*257amount of the principal and interest installments due and delinquent not theretofore ordered to suit by foreclosure. This action is still pending and undetermined.
On July 20, 1935, the city of Lakeport brought an action against the present plaintiff and others to obtain a declaration of its rights and duties in respect to the improvement bonds owned by the defendants named therein. By the judgment, long since final, rendered in that case the city was ordered to prorate among the holders of matured bonds the moneys available in the bond redemption fund and to pay thirty-eight per cent of the face value of the improvement bonds and all interest thereon to the date of maturity. This judgment further provided that “Plaintiff, Town of Lake-port, make all necessary assessments and levy all necessary taxes as provided in said Act, and that said assessment and levy of taxes continue and the Plaintiff Town was thereby directed to levy and collect the same until such time as all mature and unpaid Main Street Improvement Bonds of the said Plaintiff Town, and all interest thereon as provided by law, have been fully paid, satisfied and discharged, or until funds are available for such purpose.” A similar order was made in a judgment entered in an action commenced on September 5, 1936, against the city of Lakeport by the present plaintiff seeking to have the city commanded to 11 comply with all the provisions of the Improvement Bond Act of 1915 (Statutes 1915, page 1441), and as the same have been amended prior to the issuance of the aforesaid bonds. ’ ’ This last-mentioned judgment has also long since become final. At the time of the trial of the instant action there was a balance of $4,987.50 in the Delinquent Street Assessment Fund and a balance of $2,418.48 in the Main Street Improvement Bond Fund of the city of Lakeport.
The pertinent portions of the Improvement Bond Act of 1915 relative to the available methods of enforcement of the obligation of the bonds in case of delinquencies are the following :
Section 12 in its material aspects, after specifying when the unpaid assessments that secure the payment of bonds shall be payable, reads: “Upon default in payment, the lands securing such installments and assessments shall be sold in the same manner in which real property in such city is sold, for [258]*258the nonpayment of general municipal taxes, and be subject to redemption within one year from date of sale in the same manner as such real property is redeemed from such delinquent sale, and upon failure of such redemption shall in like manner pass to the purchaser.
“The city may be the purchaser at any delinquent sale in like manner in which it becomes or may become the purchaser of property sold for nonpayment of the general municipal property tax, and in the event of its so becoming the purchaser shall pay and transfer into said redemption fund the amount of the delinquent assessment and of the delinquent interest thereon upon which said sale is made. In cases where the municipal property tax is collected by county or city and county officials and sales for nonpayment of such taxes are made to the state, the state shall be the purchaser at any such sale hereunder, but shall hold the title acquired at such sale upon behalf of the city and shall account to the city for any moneys received upon redemption or from the sale of such property, the city for the purposes of this act being deemed the real purchaser. In other eases where under the law the city is not always the purchaser at sales for delinquent municipal taxes, the city shall become such purchaser at any delinquent sale hereunder where there is no other purchaser. In the event of there being no available funds in the treasury with which to make such payment, the tax collector shall delay the entry of the certificate of sale until such funds are available, making demand in the meantime upon the city council that a suitable amount be included in the next tax levy for the purpose of providing funds with which to make such payment; provided, however, that the period of redemption from such tax sale shall not be extended thereby nor the rights or privileges of the property owner be thereby in anywise affected. In the event of such purchase being made by the city and of any. succeeding installment of such assessment or of such interest not being paid in any future year, the property shall not be sold unless there has previously been a redemption from such sale or unless under the law it is then being sold for delinquent taxes. The city shall nevertheless, unless a resale has been made by it, from time to time when due pay and transfer into said redemption fund the amount of any such future delinquent [259]*259assessment and interest pending redemption and no redemption shall be made until any such subsequent payments, with interest and penalties, shall also be paid. ’ ’
Section 11, subdivision (c), provides in part: “In the event of nonpayment of any assessment or reassessment or installment thereof, or of any interest thereon, together with any penalties and other charges accruing under the taxation ordinance of the city and not later than four years after the due date of the last installment of principal, as a cumulative remedy, the same when due and delinquent may by order of the council be collected by suit brought in the superior court to foreclose the lien thereof. . . . The foreclosure suit shall be governed and regulated by the provisions hereof, and also where not in conflict herewith by the codes of this state. . . . Upon the ordering of any such foreclosure suits the tax collector shall be credited upon the assessment-roll then in his hands with the amount charged against him on account of such assessments or reassessments ordered to suit and be relieved of further duty in regard thereto. ’ ’
Section 16, subdivision (a), provides: “The city council may, and in the event of demand by the tax collector therefor as provided in section twelve hereof must, at the time of fixing the annual tax rate and levying the taxes to be collected for general municipal purposes, levy a special tax upon the taxable property in the city for the purpose of paying for the lands purchased or to be purchased at such tax sales, but not to exceed for each local improvement ten cents on each one hundred dollars of assessable property. ’ ’
It is the position of the respondents herein that when assessments upon property securing the bonds are in default, the city, under the above-quoted provisions of the bond act, has two independent courses which it may, at its option, pursue. One is the sale by the tax collector in the same manner as other property of a municipality is sold for delinquent taxes, and the other is an action in foreclosure. They insist that since the city of Lakeport has elected to avail itself of the latter remedy and has commenced appropriate foreclosure proceedings (§ 11 [e]), it cannot be compelled to adopt the other alternative and hold a tax sale of the delinquent properties (§12). But this construction of the statutory language does not take into account the scope of liability that [260]*260the act under consideration imposes on the municipality and the coordinating provisions thereof prescribing the municipality’s duties respecting the bonds upon the occurrence of delinquencies. The act must be considered and applied in all of its parts, and each section must be reconciled with the others and be made effective if possible, Consistent with the views expressed in two previous decisions of this court wherein the relationship of the sections here involved was discussed, American Co. v. City of Lakeport, 220 Cal. 548 [32 P.2d 622], and Hammond v. City of Burbank, 6 Cal.2d 646 [59 P.2d 495], the mere fact that the city of Lakeport has evinced an intention to proceed with foreclosure proceedings does not preclude the granting of relief to the appellant bondholder under the present circumstances.
By the provisions of section 12 of this act, when a tax sale is had and the city becomes the purchaser of the property, it becomes its duty to pay the amount of the delinquent assessment into a bond redemption fund. Such funds are thereupon used to redeem the bonds. If there are no funds available to the city to make such payment, it is the mandatory duty of the city to levy a ten-cent tax as stipulated in section sixteen, subdivision (a), of this act. After announcing these principles in American Co. v. City of Lakeport, supra, a case concerning this same bond issue, this court, significantly commented upon the effect of the foreclosure provision, at page 562:
“We come now to the final problem, that of interpretation of sections 11, 12 and 16 of the statute, and the relation each bears to the others. It is first contended by respondents that there is no mandatory duty to levy taxes under sections 12 and 16, since the city may, at its election, proceed to foreclose under section 11(c). The answer to this is found in the statute itself, which expressly declares the provision for foreclosure to be a cumulative remedy. It is different in character and procedure, and is slower, more expensive and less efficient than the tax sale. While it majr perhaps be resorted to either before or after a tax sale, the commencement of foreclosure proceedings cannot, under the act, be deemed an excuse for nonperformance of any duty under sections 12 and 16, to levy taxes to pay for property purchased. Under section 12 the city, through the agency of [261]*261the state, becomes the real purchaser of the property at the sale. It thereupon becomes the duty of the city, as such purchaser, to pay the amount of the assessment into the redemption fund; and if it has no funds with which to do so, then the taxing provisions are applicable.” (Italics added.)
In the later case of Hammond v. City of Burbank, supra, a mandamus proceeding to compel the levy of a tax to pay the purchase price of property sold for delinquent assessments, the correlation of these particular sections was again considered in connection with the municipality’s argument that “the remedy of foreclosure is an alternative remedy (although section 11 expressly states the remedy is cumulative) and that once resorted to the foreclosure proceedings supersede proceedings had under sections 12 and 16(a).” The opinion discloses at page 659 that in reference to certain of the delinquent properties the city had instituted foreclosure proceedings under section 11 of the 1915 Bond Act, that only fifty per cent of the actions so commenced proceeded to final judgment, that solely as a test proposition but one sale was ever held under these judgments, and that it was “practically conceded that the holding of foreclosure sales would be an idle gesture, inasmuch as the cost thereof would be prohibitive, and because it was extremely unlikely that purchasers could be found.” After noting that “the foreclosure proceedings did not stop the tax sales under section 12 — they were held just the same,” the court continued at page 660: 1 ‘ The remedy of foreclosure, in our opinion, is not an alternative but a cumulative remedy, and is a remedy given to aid the city, not the bondholders. Any other interpretation of the foreclosure provisions would permit the city by purported foreclosure actions to totally escape the mandatory duties imposed upon it under section 16(a), even where, as here, it is known by all concerned that such foreclosure actions will not result in an actual sale of the property.” (Italics added.)
Recognizing the above-quoted language from the Lakeport opinion as decisive of the proposition under consideration, the court in the Hammond case succinctly concluded its discussion of the point at page 661: “It may be that when foreclosure proceedings are instituted and proceed not only to final judgment, but also to sale, then the city may be re[262]*262lieved of liability (Federal Construction Co. v. Wold, 30 Cal.App. 360 [158 P. 340]), a point we expressly refrain from deciding, but the foreclosure provisions were never intended, in our opinion, to constitute a/n alternative method of procedure so that the city by the mere commencement thereof, or by proceeding to judgment therein, should be entirely relieved of its mandatory obligation to make the ten-cent levy under section 16(a).” (Italics added.) Accordingly, a proportionate part of the special ten-cent tax levy ordered by the peremptory writ of mandate issued in the Hammond case was to provide funds to pay the purchase price of property on which the delinquent assessments were ordered foreclosed before any sale under the tax procedure was made.
The fact that in both the Lakeport and Hammond eases the precise question presented for consideration concerned the mandatory obligation of the municipality to pay for delinquent properties after purchase at a tax sale does not mitigate the force and applicability of the principles of statutory construction therein announced in connection with the present factual situation, involving the city’s attempt to escape its responsibility to so purchase under the prescribed tax procedure by the act of its council ordering foreclosure of the delinquent assessment liens. In the Lakeport case at page 553 appears a succinct and accurate statement of the purpose of the adoption of this bond act: “The Improvement Bond Act of 1915 provides for a more marketable type of security, bonds issued serially in even denominations, secured by assessments payable at the same time and in the same manner as general taxes.” Accordingly, section 12 provides that when there are no available funds in the city treasury with which to pay for property purchased at the delinquent tax sale, the tax collector shall make demand upon the city council that a “suitable amount” be included in the next tax levy to provide funds with which to make such payment. Section 16, subdivision (a), states that the city council may, and in the event of demand by the tax collector as provided in section 12 must, levy a “special tax” for the purpose of paying for lands “purchased or to be purchased” at such tax sales, but “not to exceed for each local improvement ten cents on each one hundred dollars of assessable property.” While it is clear that the Legislature by these sections [263]*263has not levied a tax, it has thereby fixed the liability of the city to pay for property purchased and has required the city to levy and collect taxes in an amount suitable for this purpose. Thus, to the extent of making this limited annual tax levy so long as its obligation is shown to exist the municipality becomes the guarantor of the improvement bonds as and when they become delinquent, the method of enforcement employed by the statute being in effect an advancement of funds, which the city may normally be expected to recover upon resale of the lands secured at the delinquent tax sales. (Kerr Glass Mfg. Corp. v. San Buenaventura, 7 Cal.2d 701 [62 P.2d 583] ; Hammond v. City of Burbank, supra; American Co. v. Lakeport, supra.)
Commensurate with the declared object of this legislation, the remedy of foreclosure with which the Bond Act of 1915 invests the city is by express terms in section 11, subdivision (e), made a cumulative and not an alternate remedy that is to be employed, not solely for the benefit of the city, but as an aid and assistance to the city in discharging its duty to the bondholders, to the end that the assessments may be collected and the bonds paid in the manner prescribed. Any money that the city receives. as the result of the foreclosure actions, over and above authorized costs, is not city money but belongs to the bondholders, and the city is trustee for them as to such money. In contrast to the municipality’s responsibility under the tax proceedings as outlined in sections 12 and 16(a), the foreclosure provision contains no stipulation for the levy of a special tax and no specific requirement that the city become the purchaser, if there is no other, at the execution sale after the judgment of foreclosure. This marked distinction as incorporated in the bond act signifies the Legislature’s intention to establish as the source of primary protection for the bondholders’ investment the tax sale procedure specified in sections 12 and 16(a), and to furnish to the city by the “cumulative remedy” of foreclosure provided in section 11(c) the means of perfecting its title to property purchased at a defective tax sale. That such a provision for the use of the city constitutes an essential feature of the statutory scheme cannot be doubted in view of the act’s provision for the city’s resale of the delinquent property purchased at tax sale in order to re[264]*264coup its expenditures in connection therewith. Moreover, the expense and delay accompanying foreclosure proceedings and sale thereunder, in contrast to the expediency and simplicity of tax sale procedure, do not recommend the municipality’s employment of the former course as a means of meeting its obligation to the bondholders and fortify the conclusion that these methods of enforcement were not intended by the Legislature to be alternative, but that foreclosure was provided as an aid to the city, to be used principally to perfect its tax title, if faulty.
To sustain their position that there is no legal duty upon the city of Lakeport to sell the delinquent property at tax sale, the respondents rely upon the following provision of section 11, subdivision (3): “Upon the ordering of any such foreclosure suits the tax collector shall be credited upon the assessment-roll then in his hands with the amount charged against him on account of such assessments or reassessments ordered to suit and be relieved of further duty in regard thereto.” But this language to the effect that when foreclosure proceedings are so ordered, the tax collector shall be credited with the amounts charged against him on account of the specified assessments, is not reasonably susceptible of the interpretation that it was thereby intended that the assessment liens would be extinguished regardless of the amount realized upon the foreclosure sale. The objection to the construction advanced by the respondents is that it gives too much effect to this single sentence of section 11(c) and not enough to sections 12 and 16(a), specifying the rights of the bondholders to have the city perform its mandatory duties under the tax sale procedure fundamental to the satisfactory operation of the act in the ease of delinquencies in the payment of assessments. Bather it must be assumed that the Legislature intended by the language under consideration that the moneys received from the foreclosure sales after the reduction of authorized costs should equal the charges before the tax collector would be entitled to remove the outstanding assessments from the records. This construction coincides with the observation in the Hammond case that “when foreclosure proceedings are instituted and proceed not only to final judgment, but also to sale, then the city may be relieved of liability.” (Italics added.)
[265]*265The respondents also urge that if following the order of foreclosure of the assessment liens, the tax collector is “relieved of further duty in regard thereto,” he is not only under no legal duty, but he has no power or authority to make demand upon the city for a tax levy to provide funds for the payment of delinquent properties purchased at tax sales. This quoted language simply indicates that the tax collector has no duty in the matter insofar as the foreclosure proceedings are concerned, but it does not render inapplicable the provisions of sections 12 and 16(a) nor negative this official’s authority and obligation to act thereunder when the circumstances demand such proceedings for the protection of the bondholders. (Hammond v. City of Burbank, supra.) The municipality’s proper responsibility under this bond act was recognized in Union Safe Deposit Bank v. City of Clovis, 23 Cal.App.2d 358 [73 P.2d 242], a decision in mandate, where it was said at page 362 in reference to section 16, subdivision (a) : “Further it has been held that failure of the tax collector to make demand on the city council to levy the tax is no defense to the proceeding. The law places such duty on the tax collector and the city cannot hide behind the failure of a city officer to perform a duty imposed upon him by law. The law regards as done that which it especially requires to be done by the tax collector in making the demands.” Upon a like basis the act of the city of Lakeport in ordering foreclosure would not permit it to escape its responsibility as defined by the bond act. Manifestly, where, as here, it is improbable that much will be realized from the foreclosure actions, the transfer of funds provisions in section 12 and the special tax provisions of section 16, subdivision (a), in connection with the tax sale proceedings are essential to the legislative scheme outlined in this bond act for the ultimate retirement of the improvement bonds, and it is reasonable to assume that the Legislature, in anticipation of just such situation as the present one, designedly used the mandatory language of these last two mentioned sections as definitive of the municipality’s duties in relation to the bondholders’ investment and characterized the foreclosure proceeding as a “cumulative” rather than an alternative remedy.
In this connection the respondents finally argue that if the city cannot escape the imposed liability involved in the tax procedure, by ordering foreclosure suits, the bond act is unconstitutional as violative of the provisions of section 18 [266]*266of article XI of the state Constitution, prohibiting the incurring of any indebtedness or liability exceeding in any year the income and revenue provided for such year without the' assent of two-thirds of the qualified electors. A complete and conclusive answer to this contention appears in the Lake-port ease, where this point was strenuously urged and thoroughly considered at pages 559-560, and the court, after a full discussion and analysis of the cases upon which the respondents here place special reliance, held that the obligation of the municipality to pay as the purchase price of property sold to it at tax sale the amount due on delinquent bonds secured thereby, is imposed by law and therefore it is not a liability within the constitutional limitation.
Adverting, to the present factual situation, it is apparent that measured by the results of the earlier foreclosure sales, the pending and undetermined foreclosure suit above mentioned insures the bondholders little or nothing in return on their investment. In fact, the city of Lakeport’s dilatory course of action in initiating and prosecuting the foreclosure proceedings undertaken in January, 1937, demonstrates its conviction that no appreciable sums will bé realized in the event foreclosure sales are held. Consistent with the view that the order of foreclosure suits by the city council does not operate to absolve the municipality of liability under the mandatory, provisions of sections 12 and 16(a) of this bond act is the adjudication of the rights and duties of the parties concerned in the two above-mentioned declaratory actions of 1935 and 1936, that is, the city of Lakeport and the present plaintiff. By the final judgment rendered in each case the city of Lakeport was ordered to levy assessments and taxes and collect the same until all matured Main Street Improvement Bonds and interest were paid, or until funds were available for such purpose. Pursuant to the terms of these respective decrees, the city through levy of the special ten-cent tax as specified in section 16, subdivision (a), has raised the sum of $4,987.50, which now stands in the Delinquent Street Assessment Fund. As settled in the Lakeport and Hammond eases, the purpose of accumulation of this latter amount is to feed the Bond Redemption Fund, and although it is to be applied ultimately to payment of the principal and interest on the improvement bonds, such transfer can only occur as the result of the city’s purchase of the delinquent properties at tax sales. Accordingly, under the above analysis of the [267]*267relevant sections of this bond act, this proceeding was properly instituted by the appellant herein to compel the holding of tax sales and to secure for itself as bondholder the full protection of its investment as contemplated by the statute. In the event the city of Lakeport does become the purchaser at the delinquent tax sale, it becomes the duty of the city to transfer the $4,987.50 at present in the Delinquent Street' Assessment Fund to the Bond Fund, wherein $2,418.48 is now held in trust for the bondholders, and thus provide $7,405.98 for redemption of the outstanding bonds. Any additional sums required by the city for payment of the purchase price of these properties will have to be raised by the continuing annual ten-cent levy upon the assessable property as specified under the terms of section 16, subdivision (a). (Hammond v. City of Burbank, supra; American Co. v. Lakeport, supra.)
The only remaining point to be considered on this appeal relates to the title acquired by the purchasers at the foreclosure sale in 1932. Decisive of this question is the following provision of section 12 of the bond act under discussion: “The purchaser, whether at tax collector’s sale or at resale by the city in the event of the city having become the purchaser, or at foreclosure sale by order of the court, shall take the property subject to all unpaid installments, interest and penalties under the same proceedings and to all public improvement assessments which may have priority thereover.” Thus, by the express terms of the statute itself the assessment liens are not extinguished by foreclosure actions, but the effect of such proceedings is to substitute a new owner, and the purchaser, after foreclosure, must pay all- delinquent assessments thereon in order to obtain clear title to the property; otherwise, the bondholders would have no protection whatsoever in respect to their investment: "While the trial court found that the individual defendants purchased the lots at the foreclosure sale in question “subject to all unpaid installments, interest and penalties under the same proceedings,” it declined to pass judgment on the point. In view of these precise findings on this matter, the trial court should have made an appropriate conclusion of law to the effect that the defendant purchasers at the foreclosure sale took title, to the property subject to the assessment liens which were unpaid at the time the foreclosure action went to judgment, and all assessments which became due subsequently.
It follows from the foregoing discussion that the plaintiff [268]*268[appellant herein] is entitled to the relief here sought. Accordingly, the judgment in favor of the defendants is reversed, with directions to the trial court to enter judgment that the individual defendants now hold the real property involved in this proceeding and described in the first amended complaint, subject to the delinquent street assessment liens as hereinabove indicated. It is further ordered that by its judgment the trial court direct the following defendant officials of the city of Lakeport — namely, the tax collector, auditor and assessor — to perform the duties enjoined upon them by law in connection with the enforcement of said street assessment liens, and in particular command the tax collector to hold a tax sale of the real property herein declared subject to these street assessment liens.
