OPINION OF THE COURT.
The first error assigned by appellant, is that the trial court erred in permitting the alleged statements of appellant before a coroner’s jury to be used in ■evidence against him in the trial for murder.
The statements were made before the coroner and jury at an official investigation of the cause of the homicide; the appellant was under arrest at the time, and taken to the inquest by an officer who had him in custody; he was questioned by the coroner and members, of the jury as to his connection with the homicide; it does not appear that he was permitted to consult counsel, or that he was warned *266that Ms statements might be used against him; appellant knew that he was under arrest charged with the murder-of deceased, and testified at the trial that the officer having him in custody liad threatened his life if he did not make the statements; and, that the officer, his father-in-law, remained in the room and in hearing when the statements were made. Appellant further testified, upon his cross-examination, that neither the Justice of the Peace-nor any member of the jury threatened him, but that “They were all very mad” and that he thought it would allay their anger to make the statements he did.
The appellant had surrendered, after the homicide, to-the Justice of the Peace and was shortly taken before the-coroner’s jury. The answers of the accused were more in the nature of an attempted justification of his act, on the-ground of self defense, than a confession of the crime charged.
His testimony as to the alleged threat of his father-in-law was flatly contradicted by the witness Aragon, the-father-in-law, as was also his testimony concerning the attitude of the jury toward him, which was contradicted by several members of the coroner’s jury.
A careful examination of the entire record fails to disclose any inducement, offered by anjnne, for the making-of the alleged confession and the only element of fear that may enter into the question is the disputed fact of the alleged threat by the father-in-law. The Justice of the Peace, acting as coroner, testified that the statements made by appellant at the time of the inquest were voluntary.
While the witness, Gregorio Garcia, was testifying, lie-being the person who reduced to writing the statement made by appellant, objection was made to his testifying, concerning such statement, upon the ground that the coroner had no right to question the appellant, and upon the further ground that it had not been shown that the coroner’s jury had been duly impaneled. This objection, in our opinion, was not sufficient to raise the point that this confession was an involuntary one.
*267 1 *266The fundamental principle of exclusion of confessions, *267as laid down in the Emilio case, 14 N. M. 156, is that.. they are to be excluded when.induced by threats or promises, hope or fear, because, under the circumstances, the temptation to speak falsely is so great as to render the statement entirely untrustworthy.
We do not consider that the present case falls • within this rule. The only inducement hinted at in the present case is the alleged threat of the father-in-law, which was contradicted and quite evidently not believed by the jury. It was purely a question of fact and disposed of by the jury.
The second principle of exclusion of confessions, as set forth in the opinion of Mr. Justice Parker, in the Emilio case, is:
“That that portion of the fifth amendment to the Constitution of the United States which provides that no person ‘shall be compelled in any criminal case to be a witness against himself/ excludes involuntary confessions."
The present case differs from the Emilio case in that the accused was questioned by the coroner, while in the Emilio case he began to talk of his own volition. Was the appellant compelled to bear witness against himself?
We are not unmindful of the fact that when the witness, Matta, the Justice of the Peace, was asked what the appellant said before the coroner’s jury, objection was made, by counsel for appellant, that it should first be determined by the court whether the statement was voluntary. The witness had previously testified that he had offered no inducement or promise in connection with the-statement and that the sjne was voluntary.
The District Court ruled that the statement, up to that time, appeared to be voluntary, and permitted the witness to testify concerning the statement. The- appellant, at this time, made no offer to show that the statement was involuntary, and we think it was incumbent upon him to-do so before he can predicate error upon the action of the trial judge in admitting the testimony in the light of his information at that time.
The rule, in this regard, as enunciated by Mr. Bishop, *268in vol. 1, New Crim. Proc., sec. 1220, meets with our full ■•approval and we believe it to be decisive upon the question. It is as follows:
“See. 1220. The Judge * * * * , and as a preliminary without' which no confession can go to a jury, determines, on testimony laid before him, both for and against, whether or not to admit the particular one; the burden being on the prosecuting power that tenders the confession. Ilis decision covers, besides the law, the fact, as to which it is not ordinarily to be disturbed or reviewed, and the jury can pass merely on the effect of the confession in evidence.”
2 We agree with this rule as laid down by Mr. Bishop and while counsel for appellant was correct in stating that it was the duty of the trial court to pass upon the voluntary character of the confession before submitting it to the jury, 3et, as stated by the trial court, up to that point the statement appeared to be voluntary, positive evidence to that effect had been introduced and the appellant •offered no evidence tending to challenge the voluntary •character of the alleged confession. Therefore, we think the court committed no error in admitting the confession in view of the evidence then before the court.
3 Subsequently in the course of the trial the defendant testified concerning the alleged threat of his father-in-law, and for the first time, by way of evidence, the defendant-challenged the voluntary character of his alleged confession. It is sufficient to meet this condition, thus developed, to saj that the Court may, even after it has admitted a confession in evidence, rule it out if satisfied by subsequent evidence that the confession was not free and voluntary.
4 We are also of the opinion that if there be a conflict of evidence and the Court is not satisfied that the confession was voluntary, the confession may be submitted to the jur3, under instructions to disregard it if, upon all the evidence, they believe it was involuntary.
Metzger v. State, 18 Fla. 481; Briscoe v. State, 67 Md. •6; Ellis v. State,- 65 Miss. 44, 7 Am. State Bep. 634.
*26912 Cyc. 482, and cases there cited; also Wilson v. United States, 162 U. S. 613-624.
There was a conflict of evidence in this respect, in the present case now under consideration, and the trial judge-submitted the question to the jury in his instructions No., 25, which we quote in full:
“In order that the statements made by the defendant before the coroner’s jury can'be taken as evidence against him, the jury must believe such statements to have been voluntarily made. If the defendant made such statements-by reason of the slightest hope of benefit or the remotest fear of injury, then such statements were not voluntarily-made, and if you shall believe that the defendant did not make such statements, voluntarily, you will not, in arriving at your verdict, take into consideration such statements as evidence against him; but on the other hand, if you believe such statements were voluntarily made, then you will give them such weight as evidence as you may believe them entitled to.”
By this submission of the question to the jury, the-trial court was within its rights and the right of the defendant was fully preserved. It might well be questioned that the alleged confession was voluntary, but it was a-question, as it finally developed, for the jury and was-properly left to the jury in view of the conflict in the-evidence as to its character.
We therefore conclude that the first assignment of error is not well taken.
The next alleged error complained of is that the Court erred in admitting the testimony of Miguel Castillo, upon the ground that he did not understand the nature - of. an-oath. The witness was a boy, fifteen years of age, apparently ignorant and illiterate. It is argued by counsel for appellant that his answer to the following question, viz:
“Q. Do you understand that God will punish you if you do not tell the truth? A. Probably, yes.” was a slender thread upon which to predicate the competency of this witness’ testimony. We agree with the At*270torney General that see. 3016, C. L. 1897, is controlling upon this question; this section is as follows:
‘‘Sec! 3016. Hereafter in the courts of this Territory no person offered as a witness shall be disqualified to give evidence on account of any disqualifications known to the common law, but all • such common law disqualifications may be shown for the purpose of affecting the credibility of any such witness and for no other purpose: Provided, however, that the presiding judge, in his discretion, may refuse to permit a’ child of tender years to be sworn, if, in the opinion of the judge, such child has not sufficient mental capacity to understand the nature and obligation of an oath/'’
5 The trial court had an opportunity to examine this witness and observe his demeanor, .and could judge his mental capacity from his manner of testifying. This Court could not intelligently review the discretion of the trial judge in the matter of question as to whether a child of tender years possesses sufficient mental capacity to understand the nature and obligation of an oath.
The legislature, in its wisdom, has vested the trial court with a discretion in such matters, which will not be reviewed, by this Court, except for a gross abuse of such discretion. This assignment is, therefore, not well taken.
The only remaining error complained of is based upon the refusal of the Court to give instructions numbered 18, 26, and 27, asked for by defendant.
While we are of the opinion that the refusal to give these instructions worked no injury to the defendant, the question of error is disposed of by the fact that no exception was taken by the defendant, to the refusal of the Court to give either of said instructions.
*271 6 *270In the recent cases of State v. Lucero, 131 Pac. 491, and State v. Eaker, 131 Pac. 489, we held that the correctness of and instructions given by the trial court will not be reviewed by this Court unless objection is interposed to the giving of such an instruction, and the same principle *271applied to both cases. This. assignment of error is fully disposed of by see. 37, chap. 57, Session Laws of 1907, which provides that exceptions to the decisions •of the Court upon any matter of law arising during the progress of a cause, must be taken at the time of such decision and no exceptions shall be taken in any appeal to any proceeding in a District Court except such as shall have been expressly decided in that Court.
Finding no reversible error in the record, .the judgment of the District Court is affirmed.
