delivered the opinion of the court.
Appeal from a decree of the Circuit Court of the city of Norfolk. Decree for defendants. Plaintiff appeals.
By an order entered in the Corporation Court of the city of Norfolk on September 12, 1924, W. D. Southall, Robert VanDenbergh, W. E. Dear, W. Ludell Baldwin, S. A. Woodward and Edgar L. White were appointed assessors to “assess the value of lands and lots, together with the improvements thereon, within the corporation of the city of Norfolk.” Woodward, Dear, Baldwin and White qualified on September 22nd. VanDen*776bergh on September 23rd and Southall on September 25th, and immediately entered up oh the discharge of their duties.
Relative to their compensation to be paid by the city, the city council on January 20, 1925, adopted the following ordinance:
“Be it ordained by the council of the city of Norfolk:
“Section 1. That the pay of the assessors appointed by the Corporation Court of the city of Norfolk, Virginia, for the assessment of real estate in the city of Norfolk during the year 1925, be fixed as follows:
. “Six Assessors at $5,000.00 each, $30,000.00, payable in equal semi-monthly installments as the salaries of other officers of the city are paid.
“Section 2. That the said board of assessors be and they are hereby directed, for the compensation herein-above provided, to assess all city owned real estate, all nbn-taxable real estate, and all the real estate of public service corporations within the city of Norfolk.
“Section 3. That the rates of pay provided for herein are subject to the following conditions:
“First. That all notes, books, papers, and any other data that may be used by the assessors in the work of the re-assessment shall be the property of the city of Norfolk, and upon completion of the work shall be deposited in the office of the commissioner of revenue, wLere it shall be subject to public inspection.
“Second. That the assessors shall make monthly reports to the city manager showing the progress of the work.
“Section 4. That this ordinance, being an emergency ordinance, shall be in force from and after its adoption.”
Due to the magnitude of the work, it soon became apparent that it would be necessary to extend the time *777for its completion, and on May 13, 1925, this time was extended by the corporation court of that city to December 1, 1925, that being the extreme limit of extension allowed by statute. The assessors were unable to complete their work by that date and did not complete it until February 13, 1926. Their final report was filed on March 8, 1926. In it they ask that each assessor be allowed as additional pay $2,450.00. Responding to this request, the city council, on April 6, 1926, adopted the following ordinance:
“Whereas, on the 12th day of September, 1924, the Corporation Court of the city of Norfolk appointed W. D. Southall, Robert VanDenbergh, E. L. White, W. Ludwell Baldwin, S. A. Woodward, and W. E. Dear, as assessors to assess the value of all lands and lots, together with improvements thereon, within this city, and on September 25, 23 and 22, 1924, they qualified as such before said court and entered upon their duties as assessors; and
“Whereas, on the 20th day of January, 1925, an ordinance was adopted by the council fixing the pay of each of the assessors at $5,000.00 for the year 1925; but at the time said ordinance was adopted it was distinctly understood that it was not to be final and conclusive as to the full pay of Messrs. Southall and VanDenbergh, and that the question of further pay to each of them was reserved for further consideration and action after the work was accomplished; and
“Whereas all of said assessors rendered valuable services to the city of Norfolk from the date of their qualification in September, 1924, to January 1, 1925, and from December 1, 1925, to March 9, 1926, when they rendered their final report to the council, for which they have not yet received any compensation whatsoever.
*778“And whereas the said W. Lndwell Baldwin furnished to the city, while said assessment was being made, the use of his automobile at an expense to himself of $800.00, for which no compensation has been made to him, therefore :
“Be it ordained by the council of the city of Norfolk:
“Section 1. That W. D. Southall and Robert VanDenbergh do each receive from the city of Norfolk the further sum of $2,500.00 for his services in this behalf, payable at once by the treasurer of the city.
“Section 2. That E. L. White, W. Ludwell Baldwin, S. A. Woodward, and W. E. Dear do each receive from the city of Norfolk the further sum of $1,700.00 for his services in this behalf, payable at once by the treasurer of the city.
“Section 3. That, if after the said payments have been made, there should remain any balance of the fund appropriated for the said assessment, the treasurer of the city is directed to pay out of said balance the sum of $800.00 to the said W. Ludwell Baldwin as compensation for the use of said automobile, or, if said balance should not equal $800.00, then the whole thereof to the said W. Ludwell Baldwin for the purpose aforesaid.”
It is to enjoin the payment of the sum so allowed that this suit is brought. Dear, Baldwin, Woodward and White answered and demurred. VanDenbergh and Southall each filed separate demurrers. Evidence was taken and the cause came on to be heard both upon the demurrers and upon its merit. The court, after striking out certain evidence as incompetent, sustain the demurrers and dismissed the bill.
In the petition for appeal is this statement:
“This case was fully matured in the court below. Answers were filed, depositions were taken, and the *779whole record is here before the court. This court should, therefore, pursuant to section 6365 of the Code, enter a final decree on the merits and not remand the case to the lower court.”
The Constitution of Virginia, section 171, provides:
“The General Assembly shall provide for a reassessment of real estate in the year 1905 and every fifth year thereafter.”
It follows that the actual assessment in this case had to be made “in the year” 1925, but the legislature in recognition of the fact that certain preliminary work might at times be necessary provided that the courts should “on or before the 1st day of January” of the' assessment year appoint the necessary assessors, Code, section 2233, and in section 2244, it said that “the assessors shall, immediately after their appointment, proceed to examine all lands and lots assessable by them, with the improvements thereon, within their respective counties, districts and corporations, and shall, upon examination, ascertain and assess the fair market value thereof.”
Unless this statute is unconstitutional we have legislative authority for the commencement of work before the beginning of the assessment year.
Under familiar rules, a statute is not to be declared unconstitutional unless it is absolutely necessary, and so we reach the conclusion that the examination might begin before the assessment year commenced, although the actual assessment had to be made within the year itself. The assessors are to begin work “immediately” after their appointment. This word is to be construed in the light o'f the circumstances in which it is used. 2 Words and Phrases (2nd Series) page 947. Whatever it means, it must be something different from the “1st of January” or the legislature would have said *780the work should begin on that day. This provision of the general law is not changed by the fact that the order of appointment provided they, the “assessors, should enter upon their duties on January 1, 1925.”
The Code, section 2250, provides for a per diem payment to be paid in part by the State and in part by the counties or corporations. Of course, this compensation would not begin to run until they went into office. That date must be certain when the per diem is allowed. It is interesting to note that the vigilant Auditor of Public Accounts has paid to these assessors this per diem for services rendered before January 1, 1925. These payments were approved by the plaintiff and by its able counsel, all of which they now say is wrong. It amounts to this: They said to the State “you and I must pay for each day’s work done in 1924, and this account setting out your part of what is due is correct.” What weight attaches to the acts of these public officials?
In Smith v. Bryan, Mayor, 100 Va. 199, 40 S. E. 652, the court said:
“It is a rule of construction that, if a statute is of doubtful import, a court will consider the construction put upon the act when it first came into operation, and that construction, after lajpse of time, without change either by the legislature or judicial decision, will be regarded as the correct construction. Sutherland on Stat. Const, section 307; Anable v. Commonwealth, 24 Gratt. (65 Va.) 563, 566; Lewis v. Whittle, 77 Va. 415, 422; Mangus v. McClelland, 93 Va. 786, 789 [22 S. E. 364.]
“So also the practical construction given to a statute by public officials, and acted upon by the people, is not only to be considered, but, in eases of doubt, will be regarded as decisive. It is allowed the same effect *781as a course of judicial decision. The legislature is presumed to be cognizant of such construction, and, when long continued, in the absence of legislation evincing a dissent, the courts will adopt that construction.”
Plaintiff earnestly insists that the term of office begins on January 1st of the assessment year. The statute does not say so, and the constitutional provision noted merely tells us when the actual assessment must be made.
We, therefore, reach the conclusion that the term of office of these assessors runs from the date of their qualification, and the per diem compensation is for work done after that date.
When does the term of office end? Unless there is some statute to show another purpose, we would naturally expect it would end when the assessment is completed and the books returned. The law does not favor an extension in ambiguous cases. Smith v. Bryan, Mayor, supra.
But the Code provisions fairly construed seem to indicate that this is not true. Section 2248 provides for correction at any time prior to the 1st of February of the second year after the assessment, but it must be on notice to the assessor, and section 2249 directs the clerk to certify any changes so made to the “proper assessor” or commissioner of revenue that he may make the corresponding correction in the book filed in the clerk’s office.
Section 2392-a is in part as follows: “Any officer charged by law with the duty of assessing taxes or levies upon land or other property, money, income or license, or any officer upon whose report such assessment is made, shall, if he is satisfied that any such assessment is erroneous and that the error was caused *782by Ms mistake, within one year from the 1st day of September of the year in which such assessment is made apply to the court in wMch such assessing officer gave bond and qualified or to whose clerk such bond and certificate of Ms qualification were returned, for the correction of such erroneous assessment.” No one in his private capacity could do tMs, and when the assessor does it he must do it by virtue of his office, the term of which is necessarily extended beyond the assessment year — in tMs case until it was abolished by an act of the General Assembly approved March 25, 1928 (Acts 1926, chapter 526), and which became effective ninety days thereafter.
Although the office was not abolished, no provision for compensation is made, and the right to a per diem allowance ceases when the assessment books are returned.
In 1884 Session Acts, page 113, the legislature made comprehensive provisions for the assessment of real estate for the year following and for every fifth year thereafter. By tMs statute the assessors were allowed $2.00 a day to be paid wholly out of the State treasury. This statute was carried into the Code of 1887 as section 446. It was amended in 1910, Session Acts, page 69. The ordinary compensation remained at $2.00 a day, but the counties were allowed to increase such per diem by an amount not less than one nor more than three dollars a day to be paid out of the county funds, and it was said: “NotMng in tMs act shall be construed as limiting the right of the councils of the several cities to increase such per diem to the assessors or assistant assessors of said cities out of the funds of said cities.” It may fairly be claimed that this amounts to an indirect expression of opinion on the part of the legislature that there was a then existing right in the cities to make such payments under the general law.
*783This section was again amended in 1915 (chapter 100). Compensation was increased to $4.00 a day, $2.00 to be paid by the State “and the other half of the same shall be paid out of the treasuries of the cities and counties for which said assessors and assistant assessors were appointed, provided, however, that the councils of the several cities shall have the right to further increase the per diem salary to the assessors and assistant assessors of the said several cities to be paid out of the fund of said cities.”
In the Code of 1919, section 446 of the Code of 1887 appeared as section 2250, and the inaccurate use of the term “the other half” remained.
In the Acts of 1920, page 68, appears a further amendment. The minimum compensation was raised to $6.00 a day. Of this $3.00 was to be paid by the State and — not the other half — but the residue by the counties and cities. As amended both the supervisors of the counties and the councils of cities were given the right to increase the compensation of assessors and the statute which governs the case in judgment says “that the councils of the several cities and the board of supervisors of the several counties shall have the right further to increase the per diem salary to the assessors and assistant assessors of the said several cities and said several counties to be paid out of the funds of said city and said county.”
From this it appears necessary that the pay be on a per diem basis. Neither the State nor the cities have power to give any other compensation, although the cities have power to pay in a gross sum or sums as was done in this case. But the proposition to be remembered after all is that it is on a per diem basis, and it is entirely clear that the cities can make no payment on account of any day for which the State was *784not in part liable. Throughout all the statutes runs this clear purpose. The pay for each day’s work was to be divided between the State and the city, but the legislature did not undertake to limit the proportion of such payments. The sum to be paid by the State is fixed, that to be paid by the city changes at the city’s will.
The State pays nothing after the books are turned in and pays nothing at all if this is not done within the appointed time. Since the State in no event pays for time after the first of December, the cities cannot. It follows that compensation ceases on that date even though the assessors do not then go out of office.
We are not here dealing with an officer who undertakes to discharge the duties of an office where the salary has been fixed. It was left with the city council to pay additional compensation when and as it saw fit. This might very well have been put off till the work had been completed and value known, and there was no good reason why a sum fixed might not be afterwards increased if it proved to be inadequate. All of this was left to the council in language as comprehensive as it could well be framed.
But it is said that when the council had once acted its power was exhausted and in support of this Kirkham v. Russell, 76 Va. 956 is cited. This was a case in which the council was authorized to elect certain officers. This it did, and then that particular council undertook while these officers were still in office to elect their successors. The court said this could not be done but that their successors had to be elected by the succeeding council, that if this could be done there' was no limit to the future into which such power might be projected. All that was done here was to allow an increase of pay, not stated, and ascertained to be *785insufficient. It was natural for competent men to require some assurance before undertaking the work, but neither they nor the council could at that time do more than guess at what would be fair. That was done and when the work was finished the city undertook to pay what seemed to it to be a just and proper sum. When $5,000.00 was suggested as fair additional pay, some of the assessors flatly declined to go on with the work and were told by members of the council in informal conferences that such additional payments would be made as seemed right and proper. Of course this did not bind the city, but it does show that we are dealing with no salary grab, all of this was in the open.
Even if the principle contended for was established by Kirkham v. Russell it could not affect the results in this case. That is not the issue before us. The ordinance of January 20, 1925, does not purport to do anything but fix the compensation for work to be done in that year, while that of April 6, 1926, on its face gives pay for that done in 1924 from September to January 1, 1925, and from December 1, 1925, to March 1, 1926, periods, with the exception of December, 1925, for which no compensation had been given at all. We have already reached the conclusion that an allowance can only be made for that done in 1924. It also appears from the record that these assessors were required to do additional work for the city. With this we have nothing to do, for the payments sought to be held up by this proceeding are for regular assessments and not for other work. Moreover these payments do not purport to be for extra work. Under the express terms of the ordinance they are additional payments-to these gentlemen for work done by them as assessors, the character of the compensation does not change, only its amount is increased. There is an item for *786automobile hire provided for. This should be paid. The city might hire an automobile, or it might buy one, if it deemed such an act was for its own interest.
The issues have been dealt with on their merits rather than on demurrer. For example, the bill charges that work was begun on January 1, 1925. Manifestly if this were true, the city should not be made to pay for work done in 1924. The work, as we have seen, was commenced in September. That done in 1924 should be paid for. That done after December 1, 1925, for reasons stated, cannot be paid for, and so taking into account the allowances made and the time for which they were made and the proportion thereof for' which the city is in fact liable, we find that there should be paid:
To S. A. Woodward...................... $858.50
To W. E. Dear................................ 858.50
To W. Ludwell Baldwin................ 858.50
To Edgar L. White, Sr................. 858.50
To Robert VanDenbergh..............1,256.43
To W. D. Southall..........................1,243.65
all of which sums bear interest from April 6, 1926, the date of the ordinance which allowed them. The decree appealed from will be modified to this extent and as modified affirmed.
Modified and affirmed.
