¶1*425Mr. Claude R. Branch, with whom Solicitor General Thacher, Assistant Attorney General Dodds, and Mr. W. Marvin Smith were on the brief, for the United States.
¶2Messrs. William C. Wolfe and John P. Grace for appellee.
¶4delivered the opinion of the Court.
¶5Section 211 of the Criminal Code declares unmailable, “ every obscene, lewd, or lascivious, and every filthy, book, pamphlet, picture, paper, letter, print, or other publication of an indecent character and provides that. “ whoever shall knowingly deposit, or cause to be deposited for mailing and delivery ” any such unmailable matter “ shall be fined not more than five thousand dollars, or imprisoned not more than five years, or both.”
¶6Under this statute Limehouse was indicted in the federal court for eastern South Carolina. The indictment contained thirty counts, each charging the unlawful deposit of “ a certain filthy letter and writing in a certain post office.” Each -set forth verbatim a separate letter. The letters contained much foul language; charged the addressees or persons associated with them with sexual immorality, and in some cases charged miscegenation and similar practices. They were coarse, vulgar, disgusting,indecent; and unquestionably filthy'within the popular meaning of that term. On the ground that no letter was obscene, lewd or lascivious within the meaning given to those terms in Swearingen v. United States, 161 U. S. 446, the District Court sustained a demurrer and quashed the indictment. The case is here by direct appeal under the Criminal Appeals Act as amended.1 We are of opinion that the judgment should be reversed.
¶7*426In Swearingen v. United States, decided in 1896, the indictment, was under Revised Statutes § 3893, which made unmailable only “ obscene, lewd, or lascivious ” matter. This Court, being of opinión that those words should be given the meaning attributed to them at common law in prosecutions for criminal libel, directed that the judgment of conviction be reversed, because the language used was not “ calculated to corrupt and debauch the mind and morals of those into whose hands it might fall ” and induce sexual immorality. 161 U. S. at 451. The indictment here under review contains no reference to “ obscene, lewd, or lascivious.” The charge is of depositing “ a certain filthy letter.” It is brought under the amendment to § 3893 of the Revised Statutes made by § 211 of the Criminal Code, Act of March 4, 1909, c. 321, 35 Stat. 1088, 1129, which inserted the words, “ and every filthy.” Now the clause reads “every obscene, lewd, or lascivious, and every filthy, book, . . . letter.” -
¶8The lower court failed to recognize that the amendment introduced, not merely a word, but a phrase. Disregarding the collocation of the words, it treated the amended clause as if it had read “obscene, lewd, lascivious, or filthy; ” and then, applying the doctrine of noscitur a sociis, gave to “filthy” the meaning attributed in the Swearingen case to the words “ obscene, lewd, or lascivious.” Thus, the court emptied the amendment of all meaning. We think that it is a more natural reading of the clause to hold that by the amendment Congress added a new class of unmailable matter, — the filthy.2 The let*427ters here in question plainly relate to sexual matters. We have no occasion to consider whether filthy letters of a different character fall within the prohibition of the Act.
¶9Reversed.
¶10Mr. Justice. McReynolds thinks the judgment should be affirmed.
