¶7“When the action is called for trial the clerk shall draw from the trial jury box of the court, one by one, the ballots containing the names of the jurors until the jury is completed or the ballots are exhausted. If the ballots become exhausted before the jury is complete, the sheriff, under the direction of the court, shall summon 'from the bystanders, or the body of the county, so many qualified persons as may be necessary, to complete the jury.”
¶8According to Section 1005, L. O. L., the sheriff summons persons named in the panel by giving written notice to each of them personally or by leaving the same at his place of residence with some person of suitable age and discretion. As each juror from the special venires was examined, and the defendant inquired of him by whom he was served, and to each one answering that he was served by some person other than the sheriff himself in person, the defendant objected because of that. This, in our judgment, amounts to a challenge to the *438panel, which is forbidden by Section 117, L. O. L. The only challenges allowed are peremptory or for cause. Challenges for cause are arranged under two subdivisions: (1)- General, that the juror is disqualified from serving in any action; or (2) that he is disqualified from serving in the action on trial. The general causes for challenge are: First, a conviction for felony; second, a want of any of the qualifications prescribed by law for a juror; and, third, unsoundness of mind or such defect in the faculties of the mind, or organs of the body, as renders him incapable of performing the duties of a juror. And the particular causes of challenge are for actual or implied bias. Sections 117-123, L. 0. L. These provisions of the Code so particularly delimit objections to jurors as to exclude almost every quasi judicial feature from the duty of the sheriff in summoning talesmen. The mere act of delivering notice is purely ministerial, and it might well happen that the sheriff himself designated the citizens of the county to be summoned and directed his deputies, or, for that matter, any one else, to hand the statutory notice to those selected. There is nothing in the objections of the defendant as reported in the bill of exceptions to exclude this hypothesis. There is no charge that the sheriff acted otherwise than fairly in the discharge of his duty.

¶10*439Except for the order in which the court required the parties to exercise their peremptory challenges, the dispute about the formation of the jury is narrowed to a consideration of the rulings on the eligibility of the last three jurors examined:
¶11
¶12
¶13The juror Cook was slightly acquainted with the defendants Caseday and Albert Green, but not with the defendant Shields. He had heard of the killing of Snyder and read about it in the local papers; had talked some with other people about it, but had not expressed any opinion himself. He was absent in Portland during the trial of Hinton, had not formed an opinion as to the guilt or innocence of Caseday, and stated that he would not take into consideration what he had heard or read of the evidence in the trial against Hinton, but would go by what was produced in the present trial; that he would not consider the fact that Hinton had been convicted unless the evidence showed a connection between Hinton and Caseday, in which event he would give some consideration to the conviction of Hinton; but on examination by the court he answered that he would surely go by the directions of the court not to consider the fact that Hinton was convicted.
¶14Bert Howard was not acquainted with any of the defendants; had heard of the killing of Oliver Snyder, had heard the name of the defendant used in connection with it only as a deputy sheriff at the time; had read the county paper; and had participated in the discussion of the reports; but had not taken enough interest in the matter to inform himself as to the facts for his own satisfaction and had not expressed any opinion as to the guilt or innocence of Caseday. He was present in Canyon City about 15 minutes while some one of counsel was arguing the case of Hinton to the jury, but who it was he did not remember.
¶15The court overruled the challenges for cause made by the defendant against the jurors Cook and Howard and permitted them to participate in the trial of Caseday.
¶16*441“A challenge for actual bias may be taken for the cause mentioned in the second subdivision of Section 121; but on the trial of such challenge, although it should appear that the juror challenged has formed or expressed an opinion upon the merits of. the cause from what he may have heard or read, such opinion shall not of itself be sufficient to sustain the challenge, but the court must be satisfied, from all the circumstances, that the juror cannot disregard such opinion and try the issue impartially.” Section 123, L. O. L.
¶17The defense, to sustain these challenges, relies upon the case of State v. Miller, 46 Or. 485 (81 Pac. 363). In that case some of the talesmen testified that they were in court at the former trial when the widow of the decedent gave her testimony; that they had talked to a good many witnesses who gave testimony at the former trial, and also to some of the jurors who returned a verdict of guilty therein; that they detailed as nearly as they could the facts involved, and, having confidence in what they said, the jurors had formed a fixed opinion as to the merits of the case which it would require strong testimony to overthrow, and which would prevent the parties starting on an equal race in the trial; but that if accepted as jurors they could lay aside such prejudice and try the case fairly and impartially. This court reversed the circuit court on this point with the statement that: “As we remember the testimony given at the former trial by Mrs. Curtis, who heard the fatal shots fired that made her a widow, we do no believe any person could listen to her recital of the facts without forming such an opinion as to render him biased as to the merits of the case. Nor could a person hear the witnesses or the jurors tell the story of the homicide, as it was unfolded in court, without forming such an opinion as to the guilt or innocence of the defendant as to render him prejudiced in the matter.”
¶18Intelligent men having any local interest in such an occurrence as a supposed murder will usually form an *442opinion about the merits by reading newspaper accounts and hearing the average neighborhood discussion of the subject. The administration of justice would become impossible if such an opinion of itself disqualified a juror. This is the reason underlying Section 123, L. O. L., supra. An opinion may be satisfactory to the man being examined as a juror, considering the fact that hitherto he has sustained no relation to the case different from any other citizen of the county. While he occupies that standpoint only, he may require testimony before changing his opinion. Under such circumstances his opinion may be in a sense fixed, because he has had no occasion to think otherwise. When a talesman having that attitude of mind is being examined, the question is whether, upon assuming the particular relation of juror in the case as distinguished from his previous general relation as a member of the community, he will abandon the concomitants of the latter and submit himself to the conditions and obligations of the former. The doctrine of the statute is that the two relations are not necessarily incompatible, but that to disqualify such a juror “the court must be satisfied, from all the circumstances, that the juror cannot disregard such opinion and try the issue impartially.”
¶19The examination of Allen, Cook and Howard reveals a mental state in them widely different from that of the jurors under consideration in the case of State v. Miller, 46 Or. 485 (81 Pac. 363.) There they had attended the trial and heard the testimony, had talked in detail with witnesses-and jurors of a former trial, and had in effect thoroughly tried and determined the issue, substantially traversing the same course to be then pursued in the new trial. The tentative opinions of the jurors here fall far short of the standard of actual bias established in that decision. In the last analysis, jury service is voluntary, a duty owing from the people to the government of the peo*443pie. The process of the court may bring before it any citizen as a juror; but, if he is unwilling to serve, he can with impunity easily display such a state of mind as to disqualify him by any fair standard. He is answerable only to his conscience for his dereliction, for no one can look into his mind, as into his pockets, and ascertain its contents. The law has left to the court the estimation of a juror’s fitness. The presiding judge sees and hears the juror, and so can far more wisely determine his qualifications than the appellate court can from a case made upon paper, and, unless a strong case of abuse of discretion by the trial court is made to appear, its decision on such a point cannot be disturbed. If a juror is honest enough fully and fairly to state to the court the sources of his information about the case and the conditional or even satisfactory opinion he entertains from that viewpoint, remembering that usually the only testimony available on examination of a juror is his own, we cannot say that the court erred in accepting the juror’s pledge to decide the issue according to the law and the evidence as given him upon the trial, notwithstanding his previous mental attitude.
¶20
¶21“The full number of jurors having been called shall thereupon be examined as to their- qualifications, first by the defendant and then by the plaintiff, and having been passed for cause, peremptory challenges shall be conducted as follows, to wit: The defendant may chai*444lenge one, and then the plaintiff may challenge one, and so alternating until the peremptory challenges shall be exhausted. After each challenge, the panel shall be filled and the additional juror passed for cause before another peremptory challenge shall be exercised, and neither party is required to exercise a peremptory challenge unless the full number of jurors are in the jury box at the time. The refusal to challenge by either party in the said order of alternation shall not defeat the adverse party of his full number of challenges, and such refusal on the part of said party to exercise his challenge in proper turn shall conclude him as to the jurors once accepted by him, and if his right of peremptory challenge be not exhausted, his further challenges shall be confined, in his proper turn, to such additional jurors as may be called. The court may, for good cause shown, permit a challenge to be taken to any juror before the jury is completed and sworn, notwithstanding the juror challenged may have been theretofore accepted, but nothing herein shall be construed to increase the number of peremptory challenges allowed by other provisions of law.”
¶22If it is correct to assume, as counsel for defendant apparently contend, that this section applies to criminal trials, the action of the court may be defended on the principle that, having adopted the statute of another State, we adopt with it the judicial construction given to the statute by the courts of that State. Crawford v. Roberts, 8 Or. 324; McIntyre v. Kamm, 12 Or. 253 (7 Pac. 27); Trabant v. Rummell, 14 Or. 17 (12 Pac. 56); Everding v. McGinn, 23 Or. 15 (35 Pac. 178). In State v. Eddon, 8 Wash. 292, 305 (36 Pac. 139), the Supreme Court of that State construed their statute from which Section 126, L. O. L., was taken, to mean that the peremptory challenges should be used first by one party and then by the other in proportion to the number allotted to each, working out as a result that, where the defendant was allowed twelve and the State six, the former should use two to the State’s one of such challenges. Similar statutes have received like construction in Idaho *445and Montana. State v. Browne, 4 Idaho 723 (44 Pac. 552); State v. Sloan, 22 Mont. 293 (56 Pac. 364).
¶23In our judgment, however, it is not necessary to rely on this construction of the law. The Code of Civil Procedure has its origin in the act of the legislative assembly of October 11, 1862, while the Code of Criminal Procedure is embodied in the act of October 19, 1864, and amendments thereto. Deady’s Code, pp. 139, 441. They are independent acts having no relation to each other except as provided by reference from the latter to the former. In the formation of the jury the Criminal Code declares that:
¶24“In criminal actions, the trial jury is formed in the manner prescribed in Chapter II of Title II of the Code of Civil Procedure, except as otherwise expressly provided in this chapter.” Section 1520, L. O. L.
¶25The Criminal Code in the same chapter excludes the civil challenge for implied bias (Section 122, L. O. L.), and substitutes one of its own (Section 1521, L. O. L.), besides dispensing with the equality in the number of peremptory challenges designated in Section 125, L. 0. L., and allowing the defendant in criminal actions double the number apportioned to the State. In these respects the Criminal Code itself provides otherwise than the Civil Code. Section 1520, L. O. L., must be construed to be a reference to the Civil Code as it was at the date of the enactment of the Criminal Code. It is as if chapter 2 of title 2 of the act of October 11, 1862, except sections 122 and 125, were reprinted in the Criminal Code as part of the latter.
¶26
¶27It is impossible within the limits of an ordinary opinion to notice in detail each one of the 141 assignments of error noted in the bill of exceptions. The principal contention of the defendant is that the court erred in admitting testimony about the actions' and private conferences between the defendants Shields, Green, and Case-day in Monument and Hamilton the evening before the killing of Snyder and of the declarations and threats of Shields and his conduct in trying to get different parties to help hang Snyder. This theory of objection runs throughout the case and is the foundation of most of the exceptions to the charge of the court. It is rare that a criminal conspiracy can be proven by direct and positive testimony. Most generally the prosecution is compelled to rely on circumstantial evidence.
¶28*447
¶29
¶30*448
¶31
¶32*449
¶33“Where a conviction for a criminal offense is sought upon circumstantial evidence alone, the State must show beyond a reasonable doubt that the alleged facts and circumstances are true, and they must be such facts and circumstances as are absolutely incompatible upon any reasonable hypothesis with the innocence of the accused and incapable of explanation upon any reasonable hypothesis other than that of the guilt of the accused. If all the facts and circumstances relied on by the State to secure a conviction can be reasonably accounted for upon any theory consistent with the innocence of the defendant, such facts and circumstances are not sufficient to sustain a conviction.”
¶34This instruction, taken as a whole, is erroneous. The term “absolutely” implies mathematical demonstration which is a degree of proof impossible in any matter involving the actions of human beings. The law does not contemplate such a degree of certainty, but requires only moral certainty to the exclusion of reasonable doubt of the guilt of the defendant. State v. Glass, 5 Or. 73.
¶35
¶36
¶37“Notwithstanding the admissions and confessions of a defendant may be given against him on his trial for crime, such admissions or confessions are not alone sufficient to warrant a conviction without some other proof that the crime has been committed.”
¶38The defendant contends that this part of the charge is erroneous because it does not state the degree of proof necessary to supplement the original admission or confession. The language is practically that of the Code (Section 1537, L. O. L.), and in that respect differs from *450the statute of the State of California from which citations are made in support of this assignment of error. The degree of proof, or, in other words, the effect of the evidence, is for the jury, and under our statute the court cannot weigh the testimony for the jury independent of the admissions or confessions.
¶39
¶40“The testimony of some witnesses has been offered by the State to show certain oral statements made by the defendant now on trial, after the death of Oliver Snyder. In criminal law a statement voluntarily made by a person of a fact only, which is as consistent with his innocence as with his guilt, and is made exculpatory, or in explanation of any suspicious or incriminating circumstances, is an admission; but when the statement carries with it a suggestion of guilt, either as to the character of his intent, or the quality of his act, and the statement is made inculpatory, such statement is in the nature of a confession.”
¶41Taken in connection with the whole of the court’s charge, the learned judge was simply distinguishing between confessions and admissions with a view of explaining the latter to the jury. There is abundant evidence in the record to authorize an instruction about admissions, for the witnesses detailed several things stated by the defendant after the killing of Snyder, and the distinction made by the court was quite proper within the meaning of State v. Heidenreich, 29 Or. 381 (45 Pac. 755), and State v. Porter, 32 Or. 135 (49 Pac. 964).
¶42Some questions about cross-examination of witnesses are raised in defendant’s brief; but none of them are meritorious or show any erroneous exercise of the court’s authority over those features of the trial as defined by our Code. Section 856, L. O. L.
¶43
¶44“If any person shall, in the commission of an unlawful act, or a lawful act without due caution or circumspection, involuntarily kill another, such person' shall be deemed guilty of manslaughter.”
¶45We are at a loss to perceive how this section applies to the case in hand unless it be claimed that in proceeding towards Canyon City with his prisoner alone after being warned of a plot to lynch Snyder, the defendant performed a lawful act without due care or circumspection on account of which the death of the prisoner occurred.
¶46
¶47
¶48In our opinion upon the whole case there is no halfway ground for the defendant to occupy between innocence and murder. The trial court went as far as proper in his favor in advising the jury about the degrees of homicide. There being no theory of the evidence upon which to predicate manslaughter, the court was right in refusing an instruction upon that point. To accede to defendant’s request in that respect would have been turning the jury loose to speculate outside of the evidence, and, as the slang goes, to “return a verdict on general principles.” It would have exposed the defendant to a danger not at all justified by the evidence or the law applicable to the case. The alternative of the defendant’s innocence or his guilt of the only species of homicide which could be derived from any reasonable theory arising from the *453testimony was fairly submitted to a jury of his peers, and that jury has decided the dilemma against him.
¶49The judgment is affirmed. Affirmed.
