This is an original application for a writ of mandamus, in this court, wherein the relator seeks to compel the insurance commissioner to designate the Spokesman-Review as the newspaper in which the insurance companies doing business in this state shall publish their annual statements for the present year, in compliance with Rem. & Bal. Code, § 6119, which provides:
“Every insurance company, corporation or association doing business in the state of Washington shall cause to be published once each year, during the month of March or of April, in two daily papers of the largest general circulation, to be designated by the insurance commissioner, one in western Washington and one in eastern Washington, a full synopsis of its annual statement as prepared by the insurance commissioner: Provided, the secretary of state shall under this act have the right to make a personal examination of the books and records of any such paper, when not satisfied with the affidavits, to determine which are the two papers of such largest circulation. The cost of such examination, when made, shall be paid by the newspapers whose books have been examined; and the refusal of the owner, manager or editor to permit of such examination will be considered prima facie evidence that such paper has not the largest paid circulation.”
The case is before us upon demurrer to the petition for the writ, and also upon answer to the petition. Our conclusion upon the demurrer, however, renders it unnecessary to notice the answer. The substance of the allegations of the petition may be stated as follows: The relator is the publisher of the Spokesman-Review, a daily newspaper published at Spokane. This paper has the largest general circulation *105of any paper in eastern Washington. Its daily circulation is 30,000 and its Sunday circulation is 49,000. The defendant on about March ——, 1909, designated the Inland Herald, a daily newspaper published at Spokane, as a paper in which the insurance companies doing business in the state should publish their annual statements. This paper does not have a general circulation equal to one-fifth of the largest circulation in eastern Washington. The amount of its circulation is not alleged, but from the allegation made by the relator, it may be assumed that its circulation is nearly one-fifth of that of the largest circulation in eastern Washington. There are from two to five daily newspapers published in eastern Washington having a larger general circulation than the Inland Herald. Prior to March 1, 1909, the relator requested the defendant to designate the Spokesman-Review as the newspaper in which the insurance companies should publish their annual statements for the present year. Thereafter he designated the Inland Herald as such newspaper for eastern Washington. Following the allegations showing these facts, the relator alleges, “Said defendant has, as aforesaid, wrongfully and unlawfully designated said Inland Herald as such paper” ; and prays that the defendant be required to designate the Spokesman-Review as the newspaper in which such publication shall be made in eastern Washington, and that his designation of the Inland Herald be annuled.
It is contended by counsel for the relator that the commissioner has no discretion in the designation of the newspaper in which the publications shall be made; that he only has to determine the fact as to which paper has the largest circulation, and then designate that paper; and that such determination of fact does not involve discretion. It is contended by counsel for the defendant that the discretion of the commissioner in designating the newspaper, is, under the law, such that the courts cannot interfere therewith, especially in the absence of action on his part amounting to an arbitrary designation of a newspaper without any exercise of honest judg*106ment; that the law does not require the commissioner to designate the newspaper having the largest circulation, but only to designate a newspaper from the class having the largest circulation, leaving it discretionary with him as to which one of that class he may designate; and that in any event his decision upon the fact as to which paper has the largest circulation, involves discretion, is final, and not reviewable by the courts.
It is important that we first determine the nature of this duty of the commissioner and to what extent it is discretionary. We may concede, for the sake of argument, that the commissioner is not entirely beyond judicial restraint in the designation of the newspapers for these publications, and still find that his discretion is such that we should not interfere with in in this case. We must first ascertain the bounds of his discretion before we can determine whether or not it has been exceeded. Now, if the commissioner’s discretion is limited only to designating one of the class of newspapers having the largest circulation in each division of the state, it is manifestly much broader than if his designation is limited to the single newspaper having the largest circulation in each division of the state. We have noticed that, by the terms of the law, the publications are to be made “In two daily papers of the largest general circulation, to be designated by the insurance commissioner.” The correct construction of this provision rests largely upon the sense in which the word “of” .is used in this paragraph. On March 6, 1905, the secretary of state, who was then under the law ex-officio insurance commissioner, requested an opinion from the attorney general upon this exact question. In compliance with that request, as was his duty under Rem. & Bal. Code, § 9037, the attorney general rendered a written opinion in which he said:
“I believe that the law, clearly indicates that the publication of the reports referred to therein, is to be in a paper which is in a class of those having the largest general circulation, and that it is not mandatory that such paper shall be *107specifically one having the largest number of subscribers; for if that were the intention of the statute, most of the remainder of the section would be more or less without meaning, especially the clause that states that the paper is ‘to be designated by the insurance commissioner, one in western Washington, and one in eastern Washington.’ It seems to me that the intention of the .statute is that these reports shall not be published in' certain smaller papers, of limited county or local district circulation; but in papers that largely and generally circulate in the two sections of western and eastern Washington, respectively.”
This opinion, with others of the attorney general, was published in usual manner, in his report to the governor and the legislature for the year 1905, at page 50. Three legislative sessions have been held since then and no change made in this law. This court has recognized the rule that the construction of a law of doubtful meaning, by the department of a state or government charged with its administration, and by its highest law officer, when such law has to do with a matter of public concern, is entitled to considerable weight in determining the intention of the legislature, though, of course, such construction is not binding upon the courts.

The word “of” is defined in Webster’s new International Dictionary as,
“In the most general sense; proceeding from; belonging to; relating to ; connected with; concerning.”
Also, as,
“Indicating the aggregate or whole of which the limited word or words denote a part, or of which a part is referred to, thought of, affected, etc.; belonging to a number or quantity mentioned; out of; from amongst; as, most of the company; the poor of his people; the flower of the family; the king of kings.”
The last quoted definition and examples seem particularly applicable to the word as here used. And it seems to us that *108the expression “of the largest general circulation” used in this law, does not necessarily mean the two papers having the largest circulation, but could as well be held to mean any two papers belonging to the class having the largest circulation, which class might well consist of more than two papers. Another argument in support of the attorney general’s view is that the law fixes no obligation whatever upon any newspaper to publish these statements, nor does the law fix any limit to, or indicate, the charge which the papers may make for such publications. It would create rather a strange situation to say that the law compelled the designation of the newspaper having the largest circulation, and at the same time fixed no obligation whatever upon such newspaper to publish the statements, nor limit the charge therefor. This, we think, indicates that the commissioner’s decision is not.to be hedged about by hard and fast rules. It may be suggested that such a paper would be eliminated from consideration by the terms of the proviso of the law; but when that proviso is critically read it can hardly be said to limit the source of the commissioner’s information to an examination of the books of a newspaper, or to affidavits furnished directly to him by such •paper. The law does not tell us what affidavits or whose affidavits he many consider. We are of the opinion that the insurance commissioner under this law has discretion to designate any one of the papers belonging to the class having the largest circulation, and to determine what papers belong to that class, although the difference in the amount of their circulation may be considerable.
Assuming, now, that the commissioner’s discretion may be so abused in designating a newspaper as to call for interference by the court, do the facts here alleged show that he has so abused his discretion. The allegations of the petition that the commissioner has “wrongfully and unlawfully designated said Inland Herald,” we think means nothing more than that such is the conclusion of the pleader from the facts alleged, and that this conclusion has for its basis only the fact of the *109difference in the amount of the circulation of the two papers here involved. According to these allegations, the Inland Herald may have a circulation of from 6,000 to 9,000. We cannot say that the designation of such a paper by the commissioner under this law, in view of the discretion which the law seems to give him, is so clearly arbitrary and capricious as to call for interference by the court, when there is no fact calling for interference save the difference in the circulation of the two papers here involved. In any event, this fact, in connection with the fact that there are evidently other papers than the Spokesman-Review belonging to the class from which the designation may be made, renders it clear that the Spokesman-Review is not entitled, as a matter of law, to such designation at the hands of this court upon the refusal of the commissioner to designate that paper.
This law was not made for the benefit of the newspapers; and while a newspaper publishing these statements would, of course, reap some financial benefit therefrom, such fact should be of no weight, in determining the question of the court’s control over the act of the commissioner in making his designation. We are not disposed to treat the question as one of private right, but only as one of public concern. If the relator has the right and legal capacity to prosecute a- proceeding of this nature to restrain or control such a public duty of a state officer, which question we do not now decide, it is only because he is a citizen of the state, interested in common with other citizens, and not because he has any private rights involved therein. In its last analysis, this becomes a question of the judiciary interfering with the executive branch of the state government in a matter involving the exercise of discretion of one of the high officers of the state, concerning a public duty only. Before the judiciary will interfere in such a case, it must clearly appear that such officer has so far departed from the line of his duty under the law, that it can be said he has in fact so far abused such discretion that he has neglected or refused to exercise any discretion. When a *110private right of a citizen is violated by an executive officer under the guise of official power there is quite a different question presented. We cannot see our way clear to interfere with the commissioner’s designation, upon the facts here alleged. The writ is denied.
