showed where we kill four times as many men as
France.
This is the condition of our comparatively safe
mines of today, but, as they showed, we are now
beginning for the first time in the history Of coal
mining in this country to open veins that are real

question.
The case against electricity, when used for pow
er, Is the most serious consideration in the whole
of the coal mining situation, because it has made
coal production cheaper and, that account, no
matter how many deaths It causes, it would be
extremely difficult to drive 1t out of the dangerous
coal fields. The saving averages about three
cents ton, but here is an instance of the lengths
to which operators have gone to make that miser.

Perhaps We are not to blame the coal operators
for reducing the cost of production to the lowest
possible point but when they do at the present
tremendous cost of human life, 1t is high time they
feel the stern hand OF regulation. So far, however
they have always been able to prevent the real
cause of some of the worst disasters being laid to
electricity. A definite cause, in any event, Is an

This whole situation was never better shown
