When the jury have agreed upon their verdict they must be conducted into court, their names called by the clerk, and their verdict rendered by their foreman. When the verdict is announced, either party may require the jury to be polled, which is done by the clerk or the court asking each juror if it is his verdict. If any one answers in the negative, the jury must again be sent out, for further deliberation. R.L. 1910, § 5010.
