Coal-getting machines, such as those of the late Mr. Firth, worked by compressed air, reduce to a minimum the waste of coal, relieve the workman of a most fatiguing labor in a constrained position, and save him from the danger to which he is exposed in the hand operation.
At the present moment, taking the statistics of 1906, a quarter only of the workers below ground are employed in mines in which there is only one coal-getting shift, and in all the mines in which there are two or more coal-getting shifts the first shift preponderates in number greatly over the second, and, therefore, in applying this system of double or multiple shifts, in so far as it is necessary to apply it, we shall not have to face the difficulty of a complete transformation in the methods of working a great many of the mines, but it will be a mere extension of the system which at present exists over a great portion of the coal-getting area.
