delivered the opinion of the court:
It is provided by section 88a of chapter 37, Hurd’s Revised Statutes of 1903, “that two or more of the judges of the criminal court of Cook county, may each hold a different *76branch of said court at the same time.” At the time of the trial of this cause, several branches of that court were in session. The jury commissioners had summoned six hundred jurors to appear at that term, and these jurors had been divided among the various branches of the court,, each juror being directed to report for service in a particular branch. Plaintiff in error was tried in the branch over which Hon. Richard W. Clifford, one of the judges of the circuit court of Cook county was presiding. 'Upon the list of jurors, who had been assigned to duty in that branch, being exhausted, jurors were transferred from other branches to that branch of the criminal court. The legality of so transferring these jurors was questioned by a challenge to the array.
Section 29 of chapter 78, Hurd’s Revised Statutes of 1903, which applies to Cook county, directs that “one or more of the judges of said court shall certify to the clerk of the court the number of jurors required at each term,” and that jurors to that number shall be drawn from the jury box kept by the jury commissioners, and “if more jurors are needed during said term, the court shall so certify, and they shall be drawn and summoned as above provided forthwith.”
Plaintiff in error’s contention is that upon the list of the jurors who had been assigned to duty in the branch of the court presided over by Judge Clifford being exhausted, others should have been drawn and summoned in accordance with the directions contained in the language last above quoted, and urges that the entire jury drawn cannot be regarded as a jury drawn for but one court, for the reason that if that was the situation, then under section 12 of chapter 78, supra, it would be the duty of the court to discharge all the jurors in excess of twenty-four. Our view is that in Cook county, where the act authorizing the appointment of jury commissioners is in force, the fourth section of the last mentioned act, being section 29, supra, governs this matter, and thát the number of jurors who should be in attendance updh a term of the criminal court is “the number of jurors re*77quired at each term,” in the language of that section, and that section 12, supra, in so far as it directs the discharge of all jurors in excess of twenty-four who appear in response to the jury summons, does not apply in that county to a court having several branches. There is but one criminal court of Cook county. All the jurors properly drawn and summoned for any term, if otherwise qualified, are eligible for service in any branch of the court which may be in session during the term of service, and may be transferred from one branch of the court to another as suits the convenience of the various branches of that court.
Plaintiff in error seeks to sustain his challenge to the array by the case of People v. Compton, 132 Cal. 484. In that case it was held that if the jurors serving in different branches of the same court were, as we think they are, members of the same panel, tickets having the names of all the jurors serving in all the branches should be placed by the clerk of the court in the box from which he draws the jury for a particular case, and that a failure in this regard was fatal to the judgment. We have frequently held that the judgment of the court below will not be reversed because a challenge to the array was overruled, unless it appears that some substantial right of the defendant was' thereby impaired. ( Wilhelm v. People, 72 Ill. 468; Siebert v. People, 143 id. 571; Healy v. People, 177 id. 306.) Following this rule, long established in this State, we are brought to a conclusion diametrically opposed to that reached by the able court which pronounced judgment in People v. Compton, supra.
The purpose of the act authorizing the appointment of jury commissioners was to secure to litigants jurors drawn at random by the clerk of the court from rfamés selected by the jury commissioners, who in turn were to be selected by the judges of the several courts of record of the county. The discretion and competency of the persons chosen as such commissioners were to be taken into consideration, the pur*78pose being to prevent abuses in the selection of juries and to insure, so far as possible, that none but competent, honest and impartial jurymen should be called into the box, and that the interest of neither party to the controversy should in any way intervene in determining what jurors should be drawn and summoned for any particular term of the court. Defendant has had the benefit of the safeguards of that act. No juror was called in his cause except one who had' been selected and drawn in the office of the jury commissioners in the manner contemplated by that act-. To adopt the view which he holds would be to require the drawing of a separate jury for each branch of the criminal court, and to do this would be to interpolate into the statute language not found there and would amount to judicial legislation.
It follows, however, that a defendant in the criminal court, previous to his arraignment, is entitled to a list of all the jurors, then selected to serve and who will be immediately engaged in service in that court, and not merely to a list of those who have already been assigned to a particular branch of the court. When he is furnished with such a list, the fact that some of the jurors on that list are then serving in other branches of the criminal court and that no tickets having the names of such jurors are placed in the "Sox ¡from which the clerk draws the particular jury for the trial of his case, is not a just cause of complaint. . If he were tried in a court having no branches or divisions and where but twenty-four jurors were in attendance, if twelve of these were engaged in considering of their verdict in another cause at the time a jury was called to try his case, tickets bearing the names of the jurors serving in such other cause would not be placed in the box from which the clerk would draw the names for the jury about to be examined and sworn. In such case, the jury is not drawn by lot from among- all the jurors, but those already actually engaged ill performing jury service are necessarily excluded. In the criminal court, jurors serving in branches other than that in-*79which plaintiff in error was tried are members of the same panel as those serving in the latter branch, but may be regarded as already engaged in actual jury service, so that their names need not be put in the box from which the jury is drawn to try the defendant in the first instance, but may be so placed therein should the list of jurors serving in the branch where the cause is being heard be exhausted, precisely as in a court without divisions or branches a jury which is considering a case comes in with a verdict while a jury is being selected in another cause and the necessity for the services of those coming in with the verdict arising, their names are placed in the box to be drawn to complete the jury in the second case.
There is in this record no evidence that tends to show the commission of the crime of rape by force. Where a conviction of the crime of rape without force is sought, to establish the corpus delicti, it is necessary that the proof should show, first, that the female was under the age of fourteen; second, that the male was over the age of sixteen; third, that sexual intercourse occurred between them. In this case the fact that the female had not reached the age of fourteen was shown by the evidence of her fathér. The fact that the sexual intercourse took place rvas shown by the evidence of the female herself and by the written confession of the male, made shortly after his arrest. This confession contained also a statement that he was forty-four years old, and his age was not otherwise proven. It is elementary that the corpus delicti cannot be proven by the confession of the defendant alone. (May v. People, 92 Ill. 343; Williams v. People, 101 id. 382; Gore v. People, 162 id. 259.) Unless the defendant was above the age of sixteen at the time of the alleged commission of the offense, there was no violation of the statute. It was as essential to prove his age as it was to establish the age of the female, or to show that fornication occurred. Either of the three elements lacking, the corpus delicti is not established. Consequently, there should be evidence tending *80to establish each of these three necessary facts aside from the confession of the defendant. So far as proving his age was concerned, there was no evidence except his confession. It follows, therefore, that without his confession there was no proof that a crime had been committed, because except he was more than sixteen years of age, no crime was committed. For the purpose of fixing the age of the defendant, persons who had seen him would have been competent to testify relative to his appearance, and such testimony would have been proper for the consideration of the jury on the question of age.
Defendant in error suggests that the defendant was present in court on the trial and that this together with the confession was sufficient to justify the jury in finding him to be more than sixteen years of age. The defendant did not take the witness stand except on a preliminary question in reference to the admission of his confession in evidence, and the jury was excluded from the court room while he was testifying on that subject. But whether he did or did not testify, the law does not allow the jury to fix his age by inspecting his person. .(Stephenson v. State, 28 Ind. 272.) While the appearance of the defendant might be conclusive evidence to the jury, there would be some difficulty in having evidence of that character preserved in the bill of exceptions for the inspection of a court of review. “To allow a jury to make up their verdict upon a disputed fact from their own individual observation would be most dangerous and unjust.” Seaverns v. Lischinski, 181 Ill. 358.
There is no merit in the other errors assigned.
The judgment will be reversed and the cause will be remanded to the criminal court of Cook county.
Reversed and remanded.
