The defendant stipulated that the substance received from Agent Woodall and analyzed by Agent McSwain was heroin. He did not stipulate that Agent McSwain would have testified that it was heroin. The court did not err when, in its instruction, it recited the stipulation and charged that “no further proof is required for the facts stated in the agreement.” Compare State v. Thornton, 17 N.C. App. 225, 193 S.E. 2d 373 (1972) (first syllabus).
*307At the close of all the evidence and after the jury had been instructed and retired for deliberation, the defendant requested the court to recall Parker and Hayes as witnesses so that the answers to questions objected to and sustained could be made part of the record. The court declined to recall those witnesses.
Since the exclusion of testimony will not be held to be prejudicial if the record fails to show what the witness would have testified had he been permitted to answer questions objected to, State v. Kirby, 276 N.C. 123, 171 S.E. 2d 416 (1970), it would be prejudicial error for the trial court to prevent a witness from giving his answer out of the hearing of the jury if requested by counsel.
Here, however, the refusal of the trial judge to allow the defendant to reopen the case and introduce further evidence after the taking of evidence had been closed is within the sound discretion of the trial judge, to be reviewed only in the case of manifest abuse. State v. Rising, 223 N.C. 747, 28 S.E. 2d 221 (1943). The time to elicit such excluded testimony, for purpose of appellate review, is immediately after the question or questions are objected to while that witness is still bn the stand or else with the agreement of the trial court, to provide for its later inclusion in the record.
Further, we find no manifest abuse or discretion in the instant case, or prejudicial error in the exclusion of the testimony sought by the defendant. Each question was directed to the drug habit, criminal record, or manner of becoming an S.B.I. undercover agent of witness Hayes. All of these facts were clearly placed into evidence in other parts of the record.
During direct examination of witness Hayes by the State, as he was describing the purchase of heroin from defendant, he testified over objection and before the court ruled on the objection that he had bought heroin from the defendant on prior occasions. The court immediately cautioned the jury not to consider the statement. Defendant’s motion for mistrial was denied, which denial is now the subject of an assignment of error properly noted.
If it be assumed that admission of the prior crime of possession was error (compare State v. Johnson, 13 N.C. App. 323, 185 S.E. 2d 423 (1971), appeal dismissed, 281 N.C. 761, 191 *308S.E. 2d 364 (1972)), such error does not justify reversal of the conviction and judgment for two reasons: (1) any harmful effect of the admission of that testimony was corrected by the court’s instruction to the jury not to consider it, State v. Perry, 276 N.C. 339, 172 S.E. 2d 541 (1970); and (2) error in the admission of evidence of the prior crime was harmless beyond a reasonable doubt in view of the other competent and overwhelming evidence of defendant’s guilt. There is not a reasonable possibility that the evidence complained of might have contributed to the conviction, or that a different verdict might have resulted if the evidence had not gotten in. Chapman v. California, 386 U.S. 18, 17 L.Ed. 2d 705, 87 S.Ct. 824 (1967); Fahy v. Connecticut, 375 U.S. 85, 11 L.Ed. 2d 171, 84 S.Ct. 229 (1963); State v. Knight, 282 N.C. 220, 192 S.E. 2d 283 (1972).
No error.
Judges Parker and Hedrick concur.
