OPINION OF THE COURT BY

The defendant was indicted for the carnal abuse of a-female child under the age of twelve years. He was found guilty of indecent assault and duly sentenced by the court. The defendant filed a motion in arrest of judgment, ’ which motion was overruled. An exception was taken, and the action of the court is assigned as error. The ground of the motion ivas that an indictment charging carnal abuse does not include the charge of *833 indecent assault and therefore the verdict tvas not responsive to the indictment. This question seems to be definitely settled by section 4151, E. L. 1925, which provides that “under an indictment charging a defendant with rape or with carnal abuse of a female child under the age of twelve years or with assault with intent to commit either of said offenses, the jury may find the defendant guilty of an indecent assault if the facts so warrant.”

The facts justifying the kind of verdict that was returned would be that the defendant had taken indecent liberties with the person of a female child under the age of twelve years without committing the graver charge of carnal abuse. In re Gamaya, 25 Haw. 414, 416. The jury by its verdict necessarily found that the defendant had not committed the crime of carnal abuse but had committed the crime of indecent assault. Without reciting the evidence we think it was sufficient to justify the conclusion of the jury that the defendant had taken indecent or improper liberties with the person of the female child mentioned in the indictment and that she was under the age of twelve years.

The defendant also excepted to. the giving of the Territory’s instruction number 9, which is as follows: “Whoever takes indecent and improper liberties with the person of a female child under the age of twelve years without committing or intending to commit the crime of rape shall be deemed guilty of indecent assault. Under an indictment charging a defendant with carnal abuse of a female child under the age of twelve years the jury may find the defendant guilty of an indecent assault if the facts so warrant.” It is contended by the defendant that the giving of this instruction was erroneous for the same reason that he contends the denial of his motion in arrest of judgment Avas erroneous and for the addi *834 tional reason that the instruction does not define “indecent and improper liberties with the person of a female child under the age of twelve years.” Section 4150, R. L. 1925, which relates to indecent assault, and which is set out in the! first clause of the instruction, does not specify the conduct necessary to constitute the offense. There is no reason therefore why the instruction should have gone beyond the language of the statute. The terms used in the statute are not technical terms requiring judicial definition ¡but ordinary everyday terms, the meaning of which is commonly understood. Whether an assault upon a female child under the age of twelve years is indecent or improper is to be determined by the commonly accepted standards of decency and propriety, and the instruction properly submitted the question to the judgment of the jury.

The only other exceptions which we deem it necessary to specifically review relate to the exclusion of certain evidence sought to be adduced by the defendant on cross-examination. The first witness introduced by the Territory was the girl who was alleged in the indictment to have been carnally abused by the defendant. Her testimony tended to show that on July 17, 1927, at the defendant’s, house at Kapaa, Kauai, defendant had sexual intercourse with her and that at that time she was a few months under twelve years of age. She also testified that her home was at Camp 35 where she lived with her father and sister and one Gabriel and that in 1927 one Caetano also lived in the house. She also testified I that at thé time of the trial, which began on March 22, 1928, Caetano was not living at her father’s house but she did not remember when he ceased to do so. On cross-examinatio'n the defendant propounded the following -questions to this witness and she made the following answers: “Q. When Caetano was there you used to *835 sleep on this hunk built alongside the wall on the side towards the kitchen didn’t you? A. Yes. Q. And Caetano slept in that same part of the house didn’t he? A. Yes. Q. And your father slept in the other side of the house? Away from the wall towards the front of the house didn’t he? A. Yes. Q. Did Caetano ever get into bed with you and your sister?” To this question the Territory made the following objection: “Object as incompetent, irrelevant and immaterial and as having no bearing whatsoever, nothing whatsoever to do with this case if the court please,” which objection the court sustained. The defendant then, in the presence of the jury, made the following offer of proof: “We will have to then state to your honor our exception and offer at this time if the court please. We offer to show if the court please, that the testimony of this witness in reply to that question would be ‘Yes,’ and followed up we would then state ‘how many times;’ the witness would then say ‘three times;’ then we would ask her ‘Did he do bad things to you in the same Avay as you said Mr. Bansuelo did?’ and the answer would be ‘Yes;’ and ‘Did you complain to your father who was in the next room or did you cry out at all?’ and the answer would be ‘No;’ and that Avhen questioned we would then fui*ther question the witness as to what date these acts occurred these acts by Caetano on her and her answer Avould be that she did not know and cannot fix the date as to them in spite of her fixing other dates. We would further follow up that line of examination by asking the witness ‘How is it that you remember the date of these alleged attacks on you by Mr. Bansuelo and you do not remember the date of the attacks on you by Caetano?” To which offer the Territory made the following objection: “My objection to the offer is that it is incompetent, irrelevant and immaterial; that it tends if the court please to shoAV other *836 certain specific acts committed by this witness with other men in a case which is practically that of rape and which is not, we submit under the laAV and conceded by counsel, admissible; that it will tend if admitted to prejudice the minds of the jurors, and on the further ground that it is not error for the court to disalloAV on cross-examination any mattérs that are not material; it is not error to disalloAV on cross-examination a question asked for laying a basis for impeaching a Avitness on immaterial matters Avhich we contend is incompetent, irrelevant and immaterial in that it does not show, if anything, to be true that this defendant is innocent of the charge made against him. We'object to the offer as made by counsel for the defense,” which objection Avas sustained by the court and the defendant reserved an exception.

One of the grounds upon Avhich the defendant claims that this proposed evidence should have been received is that it tended to disclose the immoral character of the AAdtness ahd therefore to discredit her as a witness against him. Speaking generally on the subject of cross-examining witnesses as to specific acts of immorality for the purpose of discrediting them, this court said in Territory v. Buick, 27 Haw. 28, 46, 47: “A witness on cross-examination hnay be questioned as to specific acts and as to matters showing his general moral character in so far as this might affect his credibility. The reason of the rulfe excluding questions to other witnesses as to specific acts of the Avitness Avhose character is in question does not apply here because the Avitness, being examined himself, is not called upon to defend anything which he is not prepared to defend and his answers are binding upon the cross-examiner and cannot be rebutted by other Avitnesses find thus the danger of collateral issues is avoided. Moreover, if this could not be done a dishonest Avitness Avould have the same standing as an honest one *837 and in most cases could not be impeached. His moral character can be shown (as distinguished from his character directly for truth and veracity) because experience shows that a person of general degraded character is not as worthy of belief as one of general good character. It is better that the witness be shown up for what he is, in the interests of truth and the rights of the parties, than that witnesses themselves be exempt from having their lives exposed to some extent and this exposure will be limited by the discretion of the judge and the interests of the party and his counsel. * * * Within reasonable limits a witness may, on cross-examination, be thoroughly sifted upon his character and antecedents. * * * Subject to the constitutional privilege of a witness to refuse to answer questions the answers to which may tend to criminate him, it is proper to show collateral facts that might tend to criminate, disgrace or degrade the witness if such other facts tend to weaken his credibility * * *. It is now an elementary rule that a witness may be specially interrogated upon cross-examination in regard to any vicious or criminal act of his life and may be compelled to answer unless he claims his privilege. The extent to which disparaging questions not relevant to the issue, may be put on cross-examination, is discretionary with the trial court, and its rulings are not subject to review here unless it appears that the discretion was. abused.’ Republic v. Luning, 11 Haw. 390-393. To the same effect is Territory v. Goo Wan Hoy, 24 Haw. 720, 726, 727.”

The rule thus laid down is not questioned but it is contended by the Territory that it has no application when, as in this case, the prosecuting witness, whose sexual acts with some one other than the defendant are sought to be exposed by cross-examination, was at the time such acts were supposed to have been committed under twelve years of age and therefore incapable of *838 giving her consent. Upon this question there is conflict of judicial opinion. In People v. Abbott, 97 Mich. 484, 486, the court in discussing this question said: “But here the law conclusively presumes that the girl could not give, her consent, and every act of intercourse with her would be a crime committed against her, and such acts could not therefore affect her credibility. Her reputation for truth and veraqity could be inquired into, the same as of an adult, but she could not be impeached by her acts of intercourse.” To the same effect is People v. Johnson, 106 Cal. 289, where the court said: “While, as a general rule, both the general reputation of a prosecutrix for unchastity and particular acts of unchastity may be proven in a criminal action, involving an intent to commit rape, yet, where the prosecuting witness is under the age of consent, no evidence either of general reputation or specific acts of unchastity is admissible, either as going to the question of consent, or as going to the credibility of her testimony in its entirety.” In State v. Smith, 18 S. D. 341, 343, the court said: “Under our statute it is rape to carnally know a female child under the age of 16 years, either with or without her consent, and no evidence of specific acts of similar unchaste conduct with men other than the accused is admissible to show consent, or for the purpose of further disgracing the child, or as bearing upon the credibility of her testimony. In State v. McKiel, 259 Pac. (Ore.) 917, 918, the court said: “Counsel for appellant, for the purpose of attacking the credibility of the prosecutrix, propounded many questions concerning, other acts of alleged unchastity by her. Since the girl was under the age of consent and force is not an essential element of the crime, it is clear that this line of inquiry was not proper and had no relevancy to the issue.” In this jurisdiction a female child under twelve is conclusively presumed by law to be incapable of giving *839 her consent to sexual intercourse. This presumption is based on her mental and physical immaturity and her incapacity to realize the moral turpitude of such conduct. It would be a contradiction, therefore, to say that notwithstanding her innocence in the eyes of the law her credibility may nevertheless be attacked by eliciting from her, on cross-examination, confessions of conduct, the moral quality of which she was incapable of comprehending. It is an appreciation by the witness, when the act was committed, of its evil nature that renders proof of the act admissible for the purpose of discrediting her. If through lack of sufficient age the witness is conclusively presumed not to have had this appreciation the act, so far as she was concerned, was entirely innocent and cannot be considered as a reflection on her moral character and therefore on her veracity. It is our conclusion that the evidence offered by the defendant was inadmissible for the purpose of discrediting the prosecuting witness.

The defendant also contends that the fact which he offered to prove by the prosecuting witness was made relevant by the deposition of Dr. Boyden, a physician, which was offered and read to the jury by the Territory. Dr. Boyden testified that in November, 1927 (some four months after the occurrence alleged in the indictment), he examined the prosecuting witness and found a vaginal condition which in his opinion was caused either by sexual intercourse or masturbation, he could not say which. The defendant claims that in view of this medical opinion he should have been allowed to prove by the prosecuting witness that she had had intercourse with Caetano in order that the jury might determine whether Caetano or the defendant was responsible for the condition in Avhich Dr. Boyden found her. One ansAver to this contention is that the jury acquitted the defendant of sexual intercourse Avith the prosecuting witness so the *840 testimony of Dr. Boyden, tending to show sexual intercourse, was either not accepted by the jury or the jury concluded that if there had been such intercourse it was not committed by the defendant. If, on the other hand, the-jury believed that the vaginal disturbance from which the doctor1 found the prosecuting witness suffering was caused by masturbation there was no evidence tending to lay the responsibility npon the defendant. The only witnesses who testified to what the defendant did to the prosecuting witness were the prosecuting Avitness herself and her ten-year-old sister. The former testified to a consummated act of sexual intercourse. The latter testified that she saw the defendant liemo (take off) her •sister’s pants and go on top of her. There is nothing in this testimony tending to shoxv that the defendant committed the ¡masturbation Avhich Dr. Boyden testified might have caused the prosecuting Avitness’s vaginal disorder. It did tend to show either a completed sexixal act or an indecent assault. The jury found that the sexual act Avas not committed but that an indecent assault Avas committed. Under these' circumstances it Avas immatexfial whether Caetano had sexual intercourse with the prosecuting witness or not.

Another reason Axdiy this contention cannot be sustained is that at the time the offer of proof Avas made Dr. Boyden’s deposition had not been offered or read to the jury nor Avas the trial court informed that it would be offered. If the defendant desired to predicate the relevancy of the proof which he offered to make upon the deposition of Dr. Boyden he shoxxld at least have called the attention of the court to the deposition and the testimony which it contained.

We havé also given careful consideration to the other exceptions and find them without merit.

The exceptions are overruled.
