delivered the opinion of the court.
Sabeos corpus. The defendant is held in custody by the sheriff of Silver Bow county by virtue of a warrant issued by a justice of the peace upon a complaint which charges in effect that upon the twenty-third day of August, 1925, being Sunday, the defendant was guilty of keeping open, operating and maintaining the Castle Dance Hall, “the said Castle Dance Hall not being then and there maintained or conducted in a public park or playground where no admission is charged,” in violation of section 11039, Revised Codes of 1921, quoted later.
This section, a Sunday observance law, in the main, has had a constant place in the statutes of Montana for over half a century. Its forerunner was enacted in that period of our history which the uninformed might deem the wild, careless, early days. This was “an Act for the better observance of the Lord’s Day,” passed at the third session of the Legislative Assembly of the territory, approved December 13, 1866, the first section of which reads: “Hereafter it shall be unlawful for any person or persons to keep open any playhouse, theater, dance hall, hurdy-gurdy house, prize ring, or race ground on the first day of the week, commonly called the Lord’s Day.” It will be remembered that this legislation, in common with all other laws passed at the *334second and third sessions, was annulled by Act of Congress approved March 2, 1867 (14 Stats, at Large, p. 427, sec. 6).
The Legislative Assembly at its seventh session, begun December 4, 1871, enacted the Codified Statutes, in which we find the following: “Sec. 142. It shall be unlawful for any person to keep open any playhouse, theater, dance house, hurdy-gurdy house, prize ring, race tract (sic), or to keep open any banking game at cards, on the first day of the week, commonly called Sunday or the Lord’s Day. * * * (Chapter X, Offenses against Public Morality, Health and Police.” [Codified Statutes 1871-72, p. 302].) The last-quoted language, in so far as it related to any playhouse, theater, dance-house, hurdy-gurdy house, prize-ring or race.track was carried forward upon our statute books, without material deviation (sec. 849, Rev. Stats. 1879, p. 586; sec. 1406, Comp. Stats. 1887, p. 1039) until 1895, when the following appeared as section 530 of the Penal Code: “Every person who on Sunday, or the first day of the week, keeps open or maintains or aids in opening or maintaining any theater, playhouse, dance house, race track, gambling house, concert saloon or variety hall is guilty of a misdemeanor.” Section 530 was re-enacted as section 8369 of the Revised Codes of 1907 and so it remained until amended by an Act of the Fourteenth Legislative Assembly, approved March 6, 1915.
The title of the 1915 Act reads: “An Act to amend section 8369, Revised Codes of Montana of 1907, with reference to the observation of. Sunday,” and the section as amended (Sess. Laws 1915, Chap. 92, p. 146), now appearing in the 1921 Codes as section 11039 (except as to the preposition “in” inclosed in brackets, omitted by the commissioner), reads as follows: “Every person who on Sunday, or the first day of the week, keeps open or maintains, or who aids in opening or maintaining any dance hall, dance house, race track, gambling house or pool room, variety hall, or [in] any other place of amusement where any intoxicating liquors are *335sold or dispensed, is guilty of a misdemeanor; provided, however, that the provisions of this section shall not apply to such dancing halls or pavilions as are maintained or conducted in public parks, or playgrounds where no admission is charged, and where good order is maintained, and where no intoxicating liquors are sold.” The statute is clearly within the police power of the state. (State v. Penny, 42 Mont. 118, 31 L. R. A. (n. s.) 1155, 111 Pac. 727.)
The sole question for solution is: Does the statute as amended in 1915, and now existing, prohibit the operation on Sunday of a dance-hall not of the character of those mentioned in the proviso? The defendant insists that “the legislature amended the law for the sole purpose of keeping closed on Sunday all forms of amusement where intoxicating liquors are sold or dispensed,” and it is not charged that the defendant in keeping open and maintaining the Castle Dance Hall offended in that particular. In other words, it is argued that when the legislature followed the language of the time-honored' statute with the clause “or any other place of amusement where any intoxicating liquors are sold or dispensed” it intended to relate the words “where any intoxicating liquors are sold or dispensed” to each and all of the antecedent places named: dance-hall, dance-house, race-track, gambling-house or poolroom, variety-hall or any other place of amusement.
In considering the question presented the rules of grammar, which are to be employed as the first key of interpretation (Jay v. School District, 24 Mont. 219, 61 Pac. 250; In re McDonald, 50 Mont. 348, 146 Pac. 942; State v. Centennial Brewing Co., 55 Mont. 500, 179 Pac. 296), give us little aid, and a discussion along this line would be of little, if any, avail. But when we take into consideration the history above outlined, from which the policy of the territory and state for nearly half a century prior to 1915 is perceived, the answer is indicated pretty clearly.
*336The rule is that of two constructions, either of which is warranted by the words of the amendment of a public Act, that is to be preferred which best harmonizes the amendment with the general tenor and spirit of the Act amended. (Mr. Chief Justice Chase in Griffin’s Case, Fed. Cas. No. 5815; Black on Interpretation of Laws, 356; Lewis’ Sutherland on Statutory Construction, sec. 489.) Moreover, “where a section or a part of a statute is amended, it is not to be considered as having been repealed and re-enacted in the amended form, but the portions which are not altered are to be considered as having been the law from the time when they were enacted, and the new provisions are to be considered as having been enacted at the time of the amendment.” (Sec. 93, Rev. Codes 1921; State ex rel. Jacobson v. Board, 47 Mont. 531, 134 Pac. 291; State ex rel. Paige v. District Court, 54 Mont. 332, 169 Pac. 1180; 25 R. C. L. 807.)
Now. the general tenor and spirit of the Act before amendment absolutely prohibited anyone from keeping open or maintaining any dance-house on Sunday. The ban had been upon th.e dance-house ever since 1871. The Act was a Sunday observance law, nothing else. It did not touch the liquor traffic, then a subject of lawful commerce. The law with respect to dance-houses was copied into the amended statute; it was even emphasized by the addition of dance-halls. Nothing indicates an intention to change the governmental policy which had extended over half a century; the intention seems to have been rather to fortify than to weaken that policy, except as to the modification contained in the proviso.
The legislature included within the ban not only the places of amusement which had been covered by the original Act but others, and then added the catch-all clause “any other place of amusement where any intoxicating liquors are sold or dispensed,” — a recognition of the notorious fact that the use of intoxicating liquor at public gatherings tends to disorder, which is incompatible with Sunday observance. The use *337of the word “other” was not happy; indeed, the amended statute is clumsily worded; but, in view of the history of the Act we cannot believe that by the use of the word “other” the legislature intended to change so materially the long-existing policy underlying the Sunday observance law. Had it been intended that the phrase “where intoxicating liquors are sold” should qualify dance-halls, dance-houses, race-tracks, gambling-houses or poolrooms and variety-halls, it would follow that any of such places where liquor was not sold would not come within the prohibition of the statute. Such places would be permitted to operate freely on Sunday as well as upon any other day. No such construction is permissible.
The proviso made a special exception to the general operation of the law, in the nature of a concession, it may be said, to those who enjoy dancing on Sunday, but the law-making body was particular with respect to the privilege extended; it declared “that the provisions of this section shall not apply to such dancing halls or pavilions as are maintained or conducted in public parks or playgrounds where no admission is charged, and where good order is maintained, and where no intoxicating liquors are sold.” The concluding words, “and where no intoxicating liquors are sold,” we observe from the House Journal of the Fourteenth Assembly, page 419, were not in the bill as introduced, but were added upon recommendation of the committee on judiciary; this being inspired, undoubtedly, by a desire to clarify the Act. The evident purpose was to make clear that although “dancing halls or pavilions” might be maintained or conducted in public parks or playgrounds, where no admission is charged, were excepted from the operation of the Act, these places of amusement nevertheless were not excepted from the provision respecting intoxicating liquors. The privilege extended, relaxing the law as it did, was placed under the definite restrictions named.
*338As we do not find the complainant’s construction of the statute sound, the writ is accordingly discharged, and complainant is remanded.
Writ discharged.
