In gassy mines the Manager should be specially competent, and one possessing a thorough knowledge of the principles and practice of mining, the properties of gases, and systems of ventilation; and, above all, he must be prudent and cautious, yet resolute, possessing sound judgement. He must have absolute and supreme control over the whole operations, and of the men within the mine, to maintain rigid discipline, and be perfectly free and untrammelled by any outside influences. The competency of a manager should be certified by an examination before a specially-appointed Board. The Commission consider that better results may be obtained if such examinations be oral, and probably assume a more practical form than those hitherto conducted in Great Britain for the same object.
