The general tendency of judicial practice in later years has been to emphasize the influence of the judge upon verdicts. This often extends to directing a verdict, peremptorily, for one party or the other, when the law is clear upon the facts claimed or admitted. Still more often it takes the shape of a caution as to the weight that can properly be given to certain testimony, or an opinion as to what really are the controlling sources of evidence. Without the guidance of an intelligent judge, a jury would frequently come to unfortunate and even unjust conclusions. That there should be such guidance is an essential part of the jury system, and it is generally given most effectually where the judges are the ablest and the most independent. The judge has at common law and by practice in most American States a right in his charge to comment on the evidence and intimate his opinion as to the weight which should or should not be given to any particular testimony. It is a right to be cautiously exercised, for juries are greatly influenced in their conclusions by remarks of that character. They feel that he is the head of the court, and there is a certain sentiment of loyalty to him as well as of respect for any one occupying the position in which they find him placed by the authority of the State. Sometimes this power is abused. The judge desires to indicate a decided opinion. He fears that if he put it in plain words it might seem so strong as to indicate partiality, and furnish ground of appeal. He therefore uses language, perhaps in reference to the credibility of a witness, which looks fair and even colorless on paper, but by the tone or emphasis in which some vital word is uttered, or with the aid of a shrug or glance, carries to those whom he is addressing an unmistakable conviction that he means it to be taken in a certain sense. Any such judicial action, however, is rare, and would be looked upon with disapprobation by the bar.[Footnote: See Metropolitan Life Insurance Co. _v._ Howle, 68 Ohio State Reports, 614; 68 Northeastern Reporter, 4.] If the case is one which has been pressed by counsel especially upon the sympathies of the jury, such as a suit arising out of a labor strike, or by a widow to recover for an injury resulting in her husband's death, it is customary for the court to caution them in their charge that justice and not sympathy is their rule of duty.[Footnote: Bachert _v._ Lehigh Coal and Navigation Co., 208 Pennsylvania State Reports 362; 57 Atlantic Reporter, 765.]
