Harrisburg, Pa., Dec. 25.--State Dairy and Food Commissioner Warren has been confronted with a new proposition in his crusade in Western Pennsylvania against violators of the pure food laws. Judge S. H. Miller of Mercer County, before whom several oleomargarine dealers were recently convicted for the illegal sale of "oleo," has refused to sentence them on the ground that the procedure of the State Pure Food Bureau is persecution and lacking in equity. He takes the position that grocers and saloon keepers, not being expert chemists, should at least be warned previous to arrest, and be given a chance to determine whether the foods they are handling are pure or adulterated. Judge Miller's position is a serious impediment in the way of the enforcement of the law, and Commissioner Warren is preparing to take action that may compel him to punish offenders convicted before him. Not infrequently in the judicial history of the United States there has been presented to a judge the choice between rendering a decision according to his opinion of the law and the facts and losing his seat, and rendering one according to public opinion, or the public opinion of his party friends, and keeping it. A judge of the High Court of Errors and Appeals in Mississippi was one of the earlier martyrs in the cause of judicial independence. The State had incurred a heavy bonded debt, which she found it inconvenient to pay. The Governor, who had approved the bills under which over $15,000,000 of the bonds had been issued, concluded in 1841, after the issue, that it was forbidden by the Constitution of the State, and issued a proclamation declaring them void. In a suit in chancery this question came up for decision in 1852. Meanwhile the policy of "Repudiation" had been made a political issue and the people had given it their approval by electing its advocates year after year to the highest offices. The chancellor upheld the validity of the bonds, and on appeal his decision was unanimously affirmed.[Footnote: State _v._ Johnson, 25 Mississippi Reports, 625; Memoir of Sergeant S. Prentiss, II, 268.] A few months later the term of office of one of the judges who had concurred in this opinion expired, and the people put a successor in his place who held doctrines better suited to the public sentiment of the hour.
