Before SCHWAB, C.J., and LANGTRY and FORT, JJ.
PER CURIAM.
Defendant was tried and convicted upon jury trial of the crime of assault and robbery being armed with a dangerous weapon. He did not take the witness stand.
His sole ground of appeal is that the trial court erred in instructing the jury:
"Every witness is presumed to speak the truth. This presumption may be overcome by the manner in which the witness testifies, by the nature of his or her testimony, by evidence affecting his or her character, interest, or motives, by contradictory evidence, or by a presumption."
This instruction is not erroneous. State v. Kessler, Or., 89 Adv.Sh. 55, 458 P.2d 432 (1969); State v. Blank, Or. App., 90 Adv. Sh. 285, 464 P.2d 836 (1970).
Affirmed.
