Respondent was convicted of the crime commonly designated as statutory rape. This appeal is by the state from an order granting a new trial.
From the record it appears, inter alia, that the prosecutrix was a young girl, fourteen years of age; that she lived *372with her parents at Blackfoot, Bingham County, Idaho; that respondent was her uncle by marriage; that this uncle did janitor work in the land office and a Mr. Jones’ office in Blackfoot, Idaho; that on the morning of July 2, 1916, the prosecutrix accompanied respondent to the offices herein-before mentioned; that the assault is alleged to have been committed on the second day of July, 1916, in the land office; that a child was bom to the prosecutrix as a result of said assault on the twenty-fourth day of March, 1917; that on the sixth day of May, 1918, upon application of the respondent, a new trial was granted. On the twenty-ninth day of June, 1918, counsel for the state petitioned the court for an order specifying the grounds for the granting of the new trial, and on the same day the court made a supplemental order, setting forth the reasons for the granting of said application, which are briefly stated as follows: That the court erred in excluding certain offers of evidence made on behalf of the respondent to the effect that during the month of June, 1916, between the fifteenth and twenty-ninth days of said month, respondent saw the prosecuting witness and one Jess Jones in a compromising position in the home of the prosecutrix; that during the month of June, 1916, respondent had a conversation with the prosecutrix with reference to her improper relations with Jones, in which conversation the prosecuting witness stated that she had had improper, illicit relations with said Jones; that respondeat offered to prove further by his wife, Harriet Farmer, that during the spring and summer of 1916 the prosecutrix and one of her brothers slept together in the same bed and room; second, that the evidence was insufficient to support the verdict of the jury.
It is the contention of the state that the court erred in granting respondent’s application for a new trial, for the reason that error cannot be predicated upon the exclusion of evidence tending to show that someone other than the defendant in a prosecution for statutory rape may have been the father of the child of the prosecutrix, and that the evi*373dence was sufficient to support the verdict in that it substantially established that the prosecutrix was a female of the age of fourteen years, that the defendant was not her husband, and that he had had unlawful sexual intercourse with her.
The court did not err in sustaining the objection to the offer of proof that the prosecutrix was seen hy respondent in a compromising position with Jones. Neither did the court err in excluding the offer of proof that during the spring and summer of 1916 the prosecutrix and one of her brothers slept in the same room and bed. At most, if this evidence tended to prove anything, it was that the prosecutrix had an opportunity to commit illicit acts with persons other than the respondent. (State v. Henderson, 19 Ida. 524, 114 Pac. 30.)
No proper foundation was laid for the introduction of the alleged conversation had with respondent wherein the prosecutrix stated in effect that she had had illicit relations with Jess Jones, and the action of the court in excluding this evidence was proper. C. S., secs. 8038 and 8039, provide how a witness may be impeached. Moreover, a witness may not be impeached upon any immaterial matter.
The rule is well established in this jurisdiction that evidence of particular acts of unchastity of a female under the age of consent, to discredit and impeach the prosecutrix, is not admissible. (C. S., sec. 8038; State v. Anthony, 6 Ida. 383, 55 Pac. 884; State v. Anderson, 6 Ida. 706, 59 Pac. 180; 5 Am. & Eng. Ency. of Law, 878; State v. Lancaster, 10 Ida. 410, 78 Pac. 1081; State v. Henderson, supra; State v. Pettit, 33 Ida. 326, 193 Pac. 1015.)
With respect to the insufficiency of the evidence to support the verdict, the record discloses a sharp conflict in the testimony. The trial court was in a position to observe the witnesses while upon the stand, their conduct and demeanor while testifying, and was therefore in a far better position than this court to pass upon the sufficiency of the evidence and determine whether in the interest of justice a new trial *374should be granted. The granting or refusing to grant a new trial rests largely in the discretion of the trial court, and in the absence of a clear abuse of such discretion this court will not set aside an order granting a new trial. (State v. Barter, 15 Ida. 96, 96 Pac. 116; State v. Driskell, 12 Ida. 245, 85 Pac. 499.)
Prom what has been said it follows that the order granting a new trial should be affirmed, and it is so ordered.
