I. In 1875 the defendant city passed an ordinance establishing a grade on First avenue. In 1877 or 1878 plaintiff'owned one twenty foot front lot on. said avenue, and his father was owner of the adjoining twenty-foot front, upon which they erected a three-story brick block, for commercial purposes, known as the “Preston Block.” The ordinance establishing the grade was passed prior to the erection of said block, and the building was erected in accordance with. said *73grade. In. 1887 plaintiff acquired title to the twenty feet formerly owned by his father. September 3,1886, defendant city passed an ordinance changing the grade of the street in front of plaintiff’s premises; and in August, 1887, defendant permanently improved said street, by grading, guttering, and paving the same, and lowered the surface of the street to conform to the grade last established. The last grade was about a foot lower than the grade established prior to the time ■said block was erected. Plaintiff’s damages by reason of said change in grade have not been assessed or paid. Plaintiff claims that by reason of the change in the grade his property has been damaged in the sum of over three thousand dollars. The defendant city denies •each and every allegation of plaintiff, except that it is a municipal corporation. Claims that plaintiff is estopped from claiming damages because, as it alleges, he petitioned the city to make the improvements for which he claims damages, and that said improvements were made at his request; that he has waived his right to damages. The plaintiff, in a reply, denies all of the .allegations of the answer relating to his having signed a petition for improvements. The cause was tried to a jury, and a verdict returned for plaintiff for one thousand three hundred dollars, upon which a judgment was entered.
1 *742 *73II. At the commencement of the trial, and upon its own motion, the court limited the number of witnesses touching the value of the property to seven upon each side. It is contended that this was error. The right of a trial court to limit the number of witnesses who may be called to testify to a given point has been too often recognized by this court to be an open question. It was said in Kesee v. Railroad Co., 30 Iowa, 80: “A nisi prim court must be permitted to exercise a discretion as to the number of witnesses', the order and manner of their examination, etc., in the case *74before them, else examinations and trials might be indefinitely prolonged. In the absence of manifest abuse of such discretion, an appellate court ought not to interfere.” In Bays v. Herring, 51 Iowa, 291, 1 N. W. Rep. 558, we said, “The trial court must, of necessity, have power, in the exercise of a legal discretion, to control the number of witnesses that should be. examined to establish any fact.” Everett v. Railroad Co., 59 Iowa, 244, 13 N. W. Rep. 109, Bays v. Hunt, 60 Iowa, 254, 14 N. W. Rep. 785. In Minthon v. Lewis, 78 Iowa, 622, 43 N. W. Rep. 465, we held that the court might limit the number of witnesses on any point in the case. See, also, McConnell v. City of Osage, 80 Iowa, 293, 45 N. W. Rep. 550. Counsel for appellant called seven witnesses to testify to the value-of the plaintiff’s real estate before and after the change of grade in 1886. It appeared upon the examination of two of them that they had no such knowledgeóf the value of the property as qualified them to testify relating thereto. Whereupon, he proposed to call other witnesses to the same point, and the court refused to hear them. It is claimed that the order limited the number of witnesses “to give testimony on the damages and value to seven on a side,” and, as only five of the seven he had called did give such evidence, he was entitled, under the form of the order, to call two' more. The order limited the number of witnesses upon the question of value of the property to seven on each side. Defendant was not prejudiced by the order. It knew before the case began that it was only entitled to call-seven witnesses upon the question of value® of the real estate. If two of its witnesses showed a lack of knowledge of values of the realty, and hence were not competent to' testify thereto, that was no reason for setting-aside or ignoring the order. It was defendant’s business to know before it called its- witnesses that they possessed the requisite knowledge to testify touching *75that matter. It is urged that while this rule is proper, as applied to collateral issues, it should not be held applicable to the main issue in a case. We discover no-reason for limiting the application of the rule to a particular class of cases, or to certain issues. The power thus given trial courts, when discreetly exercised, is alike applicable in all cases, and to all issues. The only question is, did the court, in this case, abuse its discretion? We see no reason for so holding. The preponderance of the evidence is not necessarily determined' by the number of witnesses on each side who’ testify touching the same facts. In our judgment, the court' very properly exercised its discretion, and there was no error in refusing to hear additional witnesses offered by the defendant as to the value of the real estate.
3 . III. Plaintiff testified that he was acquainted' with the fair market value of the property before and' after the change in the grade. Hie was asked what its-fair market value was for the purpose for which it (the-building) was erected. Another witness testified as to-the market value of the property for commercial purposes. It is said that the above is not the proper measure of damages; that the measure of damages was the-difference in value just before and after the change in the grade. We do not think that there was error in' admitting this evidence. Now, upon what is this difference in value based? Manifestly, in part, upon the use the property is intended for, and how the value of the property is aff ected, if at all, in view of the purposes for which it is adapted or used. In other words,. in- determining the market value, or difference in value, we take into consideration the uses and' purposes for which the building was erected. The evidence tended to show that the building was used for stores and offices. Such, then, was the use, whether it be called “commercial” or “trade,” or by some other *76.name. In either case it is its market value. The questions did no more than to' call for the market value before and after the change in the grade, considering the use and purposes to which the buildings were adapted. Stewart v. City of Council Bluffs, 84 Iowa, 61, 50 N. W. Rep. 219, We discover no error in the ruling.
4 5 IV. Error is assigned upon the ruling of the court .in admitting the ordinance in evidence, passed in 1875, establishing a grade on First avenue in defendant city. It is said that the ayes and nays were not called and recorded on the passage of the -ordinance, and hence it was not legally passed. Code, •section 493, requires that “on the passage or adoption -of every ordinance, * * * the yeas and nays shall be called and recorded.” The defendant city is acting under a special charter, and was never incorporated under the general incorporation laws, of which said section 493 of the Code of 1873 is a part. Nor does the law make said section applicable to cities acting under special charter: Code, section 551; Acts Twenty-first General Assembly, chapter 93, section 2; Acts Twenty-second General Assembly, chapter 14, section 2; Acts Sixteenth General Assembly, chapter 116, section 21. It does not appear, nor is it claimed, that the charter of defendant city requires that upon the passage of an ordinance the yeas and nays shall be called and recorded. Rule 18 adopted by said city, and which was offered in evidence by it, provides that “all votes taken on the adoption of ordinances shall be taken by yeas and nays, each member upon his name being called, unless for special reasons he be excused by the council, shall declare openly and without debate, his assent or dissent to the question.” The record before us shows all of the aldermen voted for the adoption of this ordinance. Inasmuch as there was no statute or rule requiring that the yeas and nays be recorded, *77we do not think that the ordinance can be successfully assailéd because no record was made of the vote. It is-true the record does not show that the yeas and nays were called, but it does show that all of the aldermen.. voted for the ordinance. Under such circumstances, we may well presume that the ordinance was adopted', or passed in the manner required by the rule. Brewster v. City of Davenport, 51 Iowa, 428, 1 N. W. Rep. 737. All of the cases cited by appellant arose in municipalities organized and acting under the general incorporation law, and therefore are not applicable in this case..
6 7 V. Objection is made to the ruling of the court, admitting the certificate of the recorder of the defendant city showing, the publication of the ordinance. Section 24 of defendant’s charter provided that ordinances shall be recorded in a book kept for that purpose, and: shall be signed by the mayor and attested by the recorder. It also provides that the “recorder- ■ shall also certify in said record book to the publication or posting of ordinances recorded therein when the same shall have been published and posted.” It also provides that before ordinances take effect they shall be “published in a newspaper printed in the city,, at least ten days, or posted in two public places in each ward, for the same length of time.” The certificate of' the recorder was to' the effect that the foregoing ordinance has been published, as provided by law, in the Daily Republican, — a newspaper published in said, city. The certificate does not show the dates of publication. It appears that the ordinance was passed on February 19,1875. It also appears that the owners of property on First avenue acted upon it in 1877 and im 1878, when they erected their buildings. It appears also that plaintiff acquired his knowledge of the fact of the passage of the ordinance-of 1875 establishing a grade on First avenue from having read it in the newspapers. It appears also that. *78-when the building was erected upon plaintiff’s lot the city engineer made a survey showing the grade as made by the ordinance of 1875. From these and other facts, it is fair to presume that the publication certified' to .was made soon after the passage of the ordinance. The ordinance introduced in this case is the original ordinance as it appears in the records of defendant city, with the recorder’s certificate attached) thereto. The charter of defendant required the recorder to certify in -said record book to the publication. This he did. True .it is that it would have been proper to' have set forth in the certificate the several dates of publication, but, :in view of the charter provision, we are not authorized to- say that the certificate, as it appears, is not a certificate “to the publication” of the ordinance. The only matter of doubt is as to whether this publication was in • fact made. We have set out facts from which we think the court was justified in holding that the ordinance was published shortly after its passage, and prior to the time plaintiff erected his building.
8 *819 *78YI. The main contention in the case arises on the •defense of estoppel or waiver pleaded by the defendant. The evidence tended very strongly to show that about April 1, 1887, and after the adoption of the last ordinance fixing a grade different from that of the ordinance of 1875, the plaintiff and other -property owners upon First avenue signed the following petition: “We, the undersigned resident owners -of property abutting First avenue between Fourth street and the Oedar river, respectfully petition that .your honorable body, proceeding under section 466 of the Code of Iowa, and Ordinance 166 of the City of Cedar Rapids, do order to be laid on said First avenue, between said limits, to-wit, between Fourth street and the Cedar river, cedar block pavement, guttering and curbing.’? "Pie- court instructed the jury that the petition .did “not amount to either a waiver of damages, if any, nor does *79it operate as an estoppel, an.d the same will not he considered by you.” An instruction embodying the opposite views was asked and refused. In support of his contention, counsel for the city relies upon the following cases: Pratt v. Railway Co., 72 Iowa, 249, 33 N. W. Rep. 666; Cook v. Railroad Co., 40 Iowa, 451; Merchants’ Union Barb-Wire Co. v. Chicago, R. I. & P. Ry. Co., 79 Iowa, 616, 44 N. W. Rep. 900; Justice v. Lancaster, 20 Mo. App. 559; Cross v. City of Kansas, 1 S. W. Rep. 749, 90 Mo. 13; City of Burlington v. Gilbert, 31 Iowa, 357; Vaile v. City of Independence, 22 S. W. Rep. (Mo. Sup.) 695; Hembling v. City of Big Rapids, 50 N. W. Rep. (Mich.) 741; Collins v. City of Grand Rapids, 54 N. W. Rep. (Mich.) 889; Andrus v. Board, 6 South. Rep. (La.) 603; Dupre v. Board, 8 So. Rep. (La.) 593, and other cases. In Pratt’s Case, 72 Iowa, 247, 83 N. W. Rep. 666, the action was to recover damages caused by the construction of a railroad along the street upon which plaintiff’s property abutted. One defense was that the road was constructed with the consent, of plaintiff. It was held that such consent was a waiver of the right to recover damages. Cook’s Case, 40 Iowa, 451, and Merchants’ Union Barb-Wire Co.’s Case, 79 Iowa, 616, 44 N. W. Rep. 900, are in principle, like Pratt’s Case. In City of Burlington v. Gilbert, .the defendant, in his petition, expressly asked for, the change of grade, and, in express terms, waived all damages. The cases of Cross v. City of Kansas and Vaile v. City of Independence are, in principle, like Gilbert’s Case. In Hembling v. City of Big Rapids, it appears that plaintiff petitioned for. the. ■establishment of a grade, and the grading of the street., It -was held, he could not recover damages caused by. stopping the flow of water resulting from the work. In Collins v. City of Grand Rapids, the plaintiff, beipg,. 'familiar-with the grade established, petitioned. the. pity; j council to grade the street abutting his lot. He sued *80the city for damages because the improvement prevented access to his lot, and the case was held to be within the ruling in Hembling’s Case. The case in 20 Mo. App. was where one signed a petition requesting the construction of a bridge, knowing that, in order to reach the bridge, certain approaches would have to be erected which would raise the surface of the street in front of his premises. He was held estopped. The cases in 6 and 8 Southern Reporter are where tax-payers were held estopped from setting up the invalidity of a tax when they petitioned for the passage of ordinances levying the tax, and actively supported and voted for the ordinances, when submitted to a vote of the taxpayers. Several of the cases above referred to are so different in facts that they cannot be considered as authority for the holding contended for by the defendant in this action. On the one hand, it is contended that, in determining as to whether plaintiff is estopped, we are to look only to the petition, and what was asked’ therein, while, on the other hand, it is claimed that in signing the petition plaintiff must be held to have acted in view of the then established grade, and that, having invoked the action of the council, he must be presumed to have acted in the light of the circumstances as they then existed. The ordinance referred to in the petition was a general ordinance of the defendant city, authorizing it, by resolution, to order streets to be paved and otherwise improved. Under it, such resolution is required to be published for ten days in a newspaper in said city, and an opportunity is afforded thereafter to all persons to appear and file written objections. So objections may be made after the work is completed, and certain notice given of the amount which it is estimated that each lot owner should pay. Provision is also made for a levy of a tax and its collection, and it is also provided that “no such improvement as herein provided for shall be ordered or *81directed unless a majority of the resident owners of the property subject to levy and assessment for such improvement petitions the] city council therefor, or unless three-fourths of all the members of the city council shall, by vote, assent to the making of the same.” This record shows that the council granted the prayer of the petitioners, and adopted a resolution or order for the paving of said First avenue. In this order is- the following: “The surface of said paving and curbing shall be laid so as to conform to the established grade * * * as established by Ordinance 257 passed on the third day of September, A. D. 1886, and known as the Davis grade.” The improvement, as actually made, was in accordance with the grade established in 1886. Now, at the time plaintiff petitioned for the paving, guttering, and curbing of the avenue in front of his premises, the ordinance of 1886, establishing the grade, was in force; and by its express terms it repealed the ordinance which was passed in 1875 establishing a grade past the same premises. No question is made as to the adoption and publication of this ordinance of 1886. He knew that if his petition was granted the improvements must be made in accordance with some established grade. Knowing that the grade of 1875 had been superseded by that of 1886, on what grade did he expect the improvementsi to' be made? It is insisted that as the petition did not mention any particular grade, and as the ordinance therein referred to did not fix a grade, all that plaintiff asked was that the improvements be made; that the city was not induced to make the improvements upon the grade of 1886 by the petition of plaintiff; that the petition did not warrant the city in-assuming that the improvements therein asked for should be made on the grade of 1886. We cannot accede to this view. ■ As we have said, plaintiff petitioned to have these improvements made. He knew *82that they would and must be made in accordance with some established grade; and we think, in view of the fact that in law he was presumed to know that the ordinance of 1886, which repealed that of 1875, was in force, and •fixed the grade he now complains of, that his petition must be interpreted and construed in the light of such facts. Plaintiff’s situation is not different from what it would have been, had he petitioned in fact that the improvements be made in accordance with the grade established in 18l86. That was the legal effect of what he asked. He had no right, under the circumstances, to think that these improvements would be made in 'conformity to the grade of 1875, which had been set aside years before. It seems to us, to say that he merely petitioned; that he is not bound, because he, in fact, did not ask that the improvements be made at any particular grade, — is to say that he did a meaningless thing, because he must have known that such work as he asked to be performed must be done on some established grade. In this view, the city was induced to act, — to do the work; and we think it had a clear right to act in the belief that the petitioners wanted the street improved on the grade which then existed. Although the city had passed the ordinance in 1886 establishing a grade, it had as yet made no attempt to conform the surface of the street to that grade, and until it did so no' property owner could complain. Now, on the faith of the.petition of plaintiff and other property owners, the city improved the street in conformity to the 1886 grade. Inasmuch as that was a change from the grade established in 1875, property owners affected by the change could recover damages from the city, if they could show that they had sustained any, by reason of such change of grade, and the physical change made in accordance therewith. We think the petition was an invitation — a request — to the city council’to make the improvements in accordance with the then existing and *83legally established grade. Having acted in strict conformity to plaintiffs request he ought not now to be heard to complain that his property has been damaged by the act of the city, — an act done at his instance. We have treated this question upon the theory that plaintiff in fact signed the petition. There is some conflict in the evidence touching this question. The court below instructed the jury that plaintiff, in signing the petition, if he did sign it, would not be estopped to claim damages, and that they should pay no attention to the petition. This, we hold, was error.
VIL Other errors are assigned. We have examined all of the questions thus presented, and discover no reversible error, except as above pointed out.— Reversed.
