The first assignment of error is based on the refusal óf the court below to remand to Vance County Recorder’s Court for *283trial. This same question was 'presented in the case of S. v. Clayton, decided this day, ante, 261. On authority of the opinion in that case, this 'assignment of error is overruled.
The appellants filed in this Court, before the case was argued, a motion in arrest of judgment ion the ground that the indictment does not 'charge an unlawful 'assembly, which is -a constituent and necessary part of the offense of riot, citing S. v. Cole, 249 N.C. 733, 107 S.E. 2d 732; S. v. Hoffman, 199 N.C. 328, 154 S.E. 314; S. v. Hughes, 72 N.C. 25; S. v. Stalcup, 23 N.C. 30.
There is but one crime 'charged in the bill of indictment in this case and it clearly charges that these defendants “unlawfully * * * together with a large crowd numbering fifty or more persons, did assemble * * * upon a public street, bearing weapons consisting of 'bricks, stones, 'dulbs and missies * * * with the mutual intent to aid and assist each other and others assembled against lawful authority and those who opposed 'them, 'did then and there violently throw and hurl •such weapons as rocks, bricks and missiles at persons and automobiles, lawfully traveling upon the public street, violently striking the same breaking therefrom glasses and inflicting other damage thereto which continued for 15 minutes or more and 'did thereby unlawfully engage in riot against the form of the statute in such cases made and provided * *
In S. v. Stalcup, supra, an unlawful assembly was charged', but there'was no charge that .the parties assembled for the purpose of doing a lawful -act in an unlawful manner or of doing an unlawful- act. However, the authorities hold an unlawful assembly may be created deliberately or by chance. In any event, the unlawful 'assembly must precede the conduct which constitutes participation in a riot. In considering what constitutes a riot or civil commotion, this Court, in Spruill v. Insurance Co., 46 N.C. 126, said: “A riot is where three or more persons actually do an unlawful -act, either with or without a common cause. To this, Chitty, in his note, says, ‘The intention with which the -parties assemble, or, at least, act, must be unlawful,’ and this qualification of Mr. Chitty is recognized by this Court in the ease of S. v. Stalcup, 23 N.C. 30.”
In the instant case, the bill of indictment not only charges that the assembly was unlawful but that the defendants and others gathered upon a public street, bearing weapons, with the mutual intent to aid and assist each other against lawful authority and others -who opposed them, etc. S. v. Cole, supra. The motion in arrest of judgment is denied.
Assignment of error No. 2 is based on exception No. 2, to 'the ad*284mission of the affidavit of F. P. Barnhart, made on 17 March 1958 and on exception No. 7, to the admission in evidence of a similar affidavit made by W. C. Blalock on 18 March 1958.
B'oth Barnhart and Blalock were Highway Patrolmen 'and were on duty at the Harriet Cotton Mill in Henderson, North Carolina, at the time of the riot charged in the bill of indictment. They both testified as witnesses for the State in the trial below. While the respective defendants were on the witness stand, each was questioned about his former affidavit. The respective affidavits were identified and admitted in evidence, at which time the court charged the jury as follows: “Members of the jury, the affidavit is offered and received for the sole purpose of corroborating the witness .if you find it does corroborate him, and for no other purpose you being the sole judge of what the testimony of the witness is. It is not .substantive evidence and will not be considered by you as such.”
After the affidavits were admitted, the defendants’ counsel cross-examined each of these witnesses with respect to the contents of his affidavit.
It has been held repeatedly that it is competent to corroborate a witness by showing that he had previously made the same statement a to the incident or transaction as that given by him in his testimony at the time. S. v. Brown, 249 N.C. 271, 106 S.E. 2d 232; Gibson v. Whitton, 239 N.C. 11, 79 S.E. 2d 196; S. v. Rogers, 233 N.C. 390, 64 S.E. 2d 572; S. v. Litteral, 227 N.C. 527, 43 S.E. 2d 84; S. v. Maultsby, 130 N.C. 664, 41 S.E. 97; Burnett v. Railroad, 120 N.C. 517, 26 S.E. 819; Gregg v. Mallett, 111 N.C. 74, 15 S.E. 936; S. v. McKinney, 111 N.C. 683, 16 S.E. 235.
In S. v. Litteral, supra, it is said: “The prosecutrix also made a statement to the officers which was reduced to writing 'and signed by her. Although she, while on the stand, did not refer to this writing, there- was- other evidence tending to identify it as her written statement. The court admitted it as corroboratory testimony and was careful to instruct the jury fully as to the nature of the testimony and the manner in which it should be considered. It was competent for the purpose for which it was offered and was properly admitted.”
Likewise, in Gibson v. Whitton, supra, we said-: “The application of the rules regulating the reception and exclusion of corroborative testimony * * * so as to keep its scope and volume within reasonable bounds, is necessarily a matter which rests in large measure in the discretion of the trial court.”
The affidavits to which the appellants object were competent as corroborative of the testimony of the witnesses testifying at 'the trial *285insofar 'as they did so corroborate such testimony and they were so limited by the trial judge. The affidavits we¡re admissible for the purpose for which they were admitted, and this assignment of error is overruled.
The appellants have failed1 to bring forward and argue their remaining assignments of error. Hence they are deemed abandoned. Rule 28, Rules of Practice in the Supreme Count, 221 N.C. at page 562, et seq.
In the trial below we find
No error.
