¶1The prosecutrix was delivered of an illegitimate child August 8, 1908. She testified that it was conceived of defendant October 27, 1907. He denied this, and the testimony of several witnesses was to the 'effect that intercourse could not have happened in the circumstance related. On the other hand, his interest in her subsequent to ascertaining her condition tended to corroborate her story. The evidence was such as to preclude any interference with the verdict by this court.

¶4III. Complaint is also made of the ninth instruction:
¶5You are instructed, gentlemen, that evidence alone *208will sustain a verdict. You are not permitted under any circumstances in reaching your verdict to indulge in mere conjecture, surmise, or speculation as to the facts; but, insofar as they have not been admitted, they must be established by the evidence as I have heretofore in these instructions indicated. It would be a reproach to justice unless you were governed absolutely and solely by the evidence in this case. It is one of the boasted privileges of our modern civilization that we have established enlightened systems of jurisprudence, and one of the jewels of our system of jurisprudence is regarded as that of the trial by jury, because it is believed that in certain classes of cases at least, men out of the general walks of life, not educated and versed in the subtleties and intricacies of the law, are more capable of reaching just conclusions upon matters of fact than is the mind of the trained jurist or lawyer, because they are not bound down and circumscribed by those rules which become imbedded in the mind of the educated lawyer, and which at times prevent-him from giving that flexibility to his judgment which the mind of the layman is enabled to do; and for the further reason that the latter is entirely ignorant of those rules, and therefore is not in anywise influenced by them. Therefore it is that the experience of the ages has demonstrated the value of the jury as an arm of the court in the determination of certain classes of questions, and, of course, that feature of our system can only remain with credit while juries continue to base their verdicts solely upon those things which they have a right under the law to consider.

¶7Ordinarily, instructions, after defining- the issues, suggest the principles of the law of evidence and lay down the rules of law, applicable to the facts, by which the jury is to be guided. These rules have been evolved and developed from the long experience of the past, and are to be observed quite as punctiliously by the juror, uneducated in the law though he be, in following the judge’s exposition thereof, as found in the instructions intended to supply the want of knowledge, as by a learned jurist when a jury has been waived. It- may be that the observance of these rules prevents the educated lawyer “from giving that *210flexibility to his judgment which the mind of a layman is enabled to do,” but ordinarily when the layman succeeds in breaking away from their observance — that is, has not been “in ‘any wise influenced by them” — the result is a miscarriage of justice, often discreditable to the jury system. Nor can it be conceded that the perpetuity of this system depends on juries continuing “to base their verdicts solely upon those things which they have a right under the law to consider” if these are outside of the matters which guide and control a judge in like investigations. As said, the court doubtless did not intend the deductions indicated, but such are the inferences reasonably to be drawn from the language employed. Indeed, the jury might well have understood that, though the verdict must be based on evidence, the jurors were at liberty to ignore those' rules which the court had laid down for their guidance and exercise that flexibility of judgment accorded to laymen in reaching a verdict; in other words, that though appropriate for a learned jurist, as for example, the judge,- the jurors were not to be influenced thereby. The cause was of a class in which sentiment is likely to and too often does play an important part, and, instead of intimating that the rules which govern all triers of fact might be relegated, the court might well have cautioned against being swayed by considerations other than the evidence and the law as laid down by the court for the jury’s guidance. Justice, whether based on the finding of court or jury; must be administered according to law. Necessarily an instruction which may be construed otherwise must be regarded as erroneous and prejudicial. — Reversed and remanded.
