There are, however, in every State quite a number of judges of higher courts who receive a salary deemed sufficient for their support and who are expected to devote their entire time to judicial duties. As respects those of the United States courts there is a statute (U. S. Revised Statutes, Sec. 713) making it criminal for them to practice law. Similar legislation exists in some of the States with regard to the judges of their higher courts, but without it a sense of propriety dictates their abstaining from it, and it has even been held that the right of any judge of a superior trial court of general jurisdiction over important causes to act as an attorney or counsellor, except in his own cause, is suspended by implication of law so long as he retains his seat on the bench.[Footnote: Perry _v._ Bush, 45 Florida Reports; 35 Southern Reporter, 225.] The demeanor of the judges to the bar is inevitably affected to some extent by their tenure of office. If they hold their places for life, they naturally are less sedulous to avoid giving offense and less ready to tolerate a poor or tedious argument. A greater distance is maintained for this cause between bench and bar in the federal courts than is usual in most of the State courts. No judge, however, desires to have the reputation of being overbearing, rough or impatient, and few are. Chief Justice Parsons of Massachusetts at one time fell into an inveterate habit on the circuit of checking counsel in argument rather curtly when they seemed to him to wander from the vital point. The leaders of the bar of Boston finally determined to stop it, and arranged at the next term at which he was to preside that whoever of them was thus treated should leave the court room. The first to address the court was checked in the usual manner, and observing that he regretted his argument seemed not worthy of the court's attention, took his papers and went out. The next met the same kind of interruption in the same way, and so on until the court room was cleared. The Chief Justice afterwards sought an explanation, received it in good part, and was forever cured of what had been a serious impediment to his usefulness on the bench.[Footnote: See George F. Hoar, Autobiography, II, 397.] Occasionally a trial judge will have a similar lesson taught him by finding no business to be disposed of when he opens court, and learning later that the bar agreed to the continuance of all pending cases, because they did not care to trust him with them, or were disinclined to submit to his manner of conducting a hearing.
