Defendant makes two assignments of error in the record oii .appeal.
[1] Defendant first assigns as error the court’s failure to allow defendant to have witnesses subpoenaed. The record reveals the following: “The Court: Make this entry. During the progress of this trial, after the jury was sworn and empaneled and evidence presented on the part of the State, the defendant in open court for the first time advised this court that he had some witnesses and he named them, who were members of *150the Rural Police in Gaston County and one was the Chief of Police of Kings Mountain; that he desired their presence, and that this fact was not known by this Court or the Clerk of the Court or any other court officials until this time during the progress of this trial; that the defendant was advised by statement by one of the Kings Mountain officers to the effect that the Chief of Police of Kings Mountain was out of the city and out of the county and not available to testify; that the other witnesses are police officers in Gaston County and their whereabouts are not known; that no request for a subpoena was made by this defendant and that none was issued. . . .”
Unquestionably the right of confrontation includes the opportunity fairly to present one’s own defense. State v. Lane, 258 N.C. 349, 128 S.E. 2d 389 (1962). However, as was said in State v. Graves, 251 N.C. 550, 112 S.E. 2d 85 (1959), “[w]e do not suggest that an accused may be less than diligent in his own behalf in preparing for trial. He may not place the burden on the officers of the law and the court to see that he procures the attendance of witnesses and makes preparation for his defense. But the officers and court have a duty to see that he has opportunity for so doing.” In our opinion defendant has had ample opportunity. He was arrested in June; true bills were returned in August; in December he filed a written waiver of counsel; and he was tried the following May. It is also obvious that this defendant was certainly not unfamiliar with procedure. This purported assignment of error is without merit.
[2] Neither is there merit in defendant’s other assignment of error, which is directed to the court’s failure to instruct the jury to scrutinize the evidence of Donald Wood, a co-defendant and this defendant’s brother, who testified for the State. “Instruction to scrutinize the testimony of a witness on the ground of interest or bias is a subordinate and not a substantive feature of the trial, and the judge’s failure to caution the jury with respect to the prejudice, partiality, or inclination of a witness will not generally be held for reversible error unless there be a request for such instruction.” State v. Reddick, 222 N.C. 520, 23 S.E. 2d 909 (1942) ; State v. Roux, 266 N.C. 555, 146 S.E. 2d 654 (1966). The record reveals no request.
No error.
Judges Brock and Graham concur.
