McClain, J.—
Defendant was convicted, on circumstantial evidence, of having set fire at night to a livery barn in the town of Grand Junction. It appears without question that, a short time before the barn was discovered to be on *251fire, tbe defendant bad purchased a jug of Kerosene oil at a grocery store not far away, and that he was seen going from the grocery store in .the direction of the barn; that kerosene had been thrown on the side of the barn before it was ignited; and that a jug.which had contained kerosene oil was found in the vicinity, which some witnesses testified was the same jug which defendant had had filled with oil at the grocery store. There was also some evidence tending to show a motive for the crime.
It is contended by the appellant that the trial court erred in refusing to direct a verdict for the defendant, and in refusing to set aside the verdict for the State on the ground of insufficiency of the evidence, and on the further ground that it was apparently the result of passion and prejudice. But the commission of the crime was clearly established, and there was some evidence tending to connect the defendant therewith. The sufficiency of the evidence was for the jury, and we have no disposition to interfere with their conclusions.
lenge 'to jurors. Complaint is made of the action of the court in impaneling the jury, first, because one juror was excused on challenge of the State, over defendant’s objection, on the ground that he was incorrectly named; and, second, that defendant’s challenge to another , ° juror on the same ground was overruled. The first of these objections is not well taken, for the reason that we cannot presume prejudice from the ruling of the court excusing the juror. Geiger v. Payne, 102 Iowa, 581" court="Iowa" date_filed="1896-12-11" href="https://app.midpage.ai/document/geiger-v-payne-7107854?utm_source=webapp" opinion_id="7107854">102 Iowa, 581. It appears that the second objection was hot made until after the counsel for defendant had waived a peremptory challenge, and there was therefore no prejudice to the defendant. State v. Elliott, 45 Iowa, 486" court="Iowa" date_filed="1877-04-04" href="https://app.midpage.ai/document/state-v-elliott-7097267?utm_source=webapp" opinion_id="7097267">45 Iowa, 486.
*2522‘ Action to ob *251One of the grounds of motion for a new trial which was overruled was that one of the jurors was related to the prosecuting witness, which fact was not divulged by the juror when examined during the impaneling of the jury. ' Their relationship was by a former marriage of the prosecuting *252witness to the first cousin of tbe juror. This marriage had been terminated twenty years before the trial by the death of the wife, but counsel for appellant contend that the survival of children of the marriage was sufficient- to perpetuate the relationship between the prosecuting witness and the juror. Without passing on this question, it is sufficient to say that the trial court, in ruling on the motion, had before it a showing that counsel for the defendant became aware of the relationship soon after the commencement of the trial, and failed to make any objection to the continuance of the trial on that account, and that he expressed to others a willingness to allow the trial to proceed without raising any such objection. Counsel argue that the nature of the relationship did not come to the knowledge of counsel until after the commencement of the trial, but we think that if at any time during the trial, and before the verdict, counsel had information that there was some relationship which might disqualify the juror, he should have called the matter to the attention of the court, in order that the juror might be interrogated and the facts ascertained, and that, by failing to urge the objection or have an investigation made for the purpose of ascertaining whether such objection existed, the ground of complaint, whatever it might be, was waived.

A number of errors are assigned as to rulings in the admission or exclusion of evidence, but, after examining the record, we reach the conclusion that the rulings were correct. It is not necessary, in our judgment, to discuss in detail the various objections, for they are as to minor matters, and do not reach the real merits of the case.
*253TION OF witnesses: discretion of court. 3. Sequestra-*252As to the objection that, after the trial court had directed the witnesses for the prosecution to be sequestered, one witness — the wife of the prosecutor — was allowed to testify, although she had remained in the court-room while *253the other witnesses were, testifying, it is sufficient to say it appeared that the officer had not carried out the court’s instructions as to confining this witness in a separate room with the other witnesses for the reason that she was the only woman among the witnesses, and the ruling of the court refusing to exclude the witness from testifying under the circumstances was fully within the exercise of a reasonable discretion.
. . 4. Alibi : rea* doubt;6 instructions. Objection is made to one of the instructions which related to the evidence relied upon to establish an alibi, on the ground that under such instruction the jury were told that the defendant was not bound to establish such defense beyond a reasonable doubt, and, if the testimony raised in the minds of the jury a reasonable doubt that the defendant was present at the time and place of the commission of the crime, then it was their duty to give him the benefit of that doubt and acquit him. The objection is that by this instruction the jury might have been led to infer that it was only reasonable doiibt raised by the evidence as to alibi that would necessitate an acquittal, but the doctrine of reasonable doubt as applied to the whole evidence was correctly stated in another instruction, so that the jury could not possibly have been misled.
appeaTew 5. Reasonable doubt on Counsel urge that the evidence is not sufficient to establish the guilt of defendant beyond a reasonable doubt, but that is for the jury to say. We do not pass on the question of reasonable doubt in reviewing a case on the evidence. If there is competent evidence tending to support the verdict, and the jury have been properly instructed with reference to reasonable doubt, their verdict is final on that question.
Finding no error to have been committed, the judgment of the trial court is affirmed.
