Our grandfathers used to make themselves miserable about the predicted
failure of the coal supply and the collapse some day of Great Britain when she would be deprived of her source of strength. But long before that day of doom need be faced with a semblance of serious- ness the whole problem has been changed. Coal divides the honours with oil ; and the thought of a failing supply of coal gives not a moment's trouble to anybody. Our coal will last as long as it is likely to be needed, and the whole question now is its proper use. But thii means a revolution of method for every mine ; electricity must be generated and distributed in quantities that were undreamed -of a few years ago,- and- coal must be treated o that we get its by-products and at the same time says ourselves from the desolation and misery of an atmos- phere injurious to health, injurious to buildings, injurious to everything and everybody.
