For the violation of the mining laws in not having danger boards placed, Saul PECK, pit boss of Cherry Valley mine No. 3 of the Pittsburg and Erie Coal Company, was arrested Saturday and given a hearing before Squire COCHRAN of McDonald. He was held for court on the charge. The prosecution was made by the miners' union. It is alleged that since the opening of the No. 3 mine PECK sent in thirty-seven men before a mine inspector had ever been in the mine and also before danger boards had been placed throughout the mine. It is alleged that the lives of the thirty-seven miners were endangered by going into this mine before the inspectors had made an examination and before the danger boards had been placed.
