Grime doesn't pay!

Are we going to have less dirt—and more nylons ? Less soot—and more plastics? Less grime—and more dol- lars? On how well we use our coal the answers must depend. Every year much of our coal is allowed to burn to waste, and all we have left to show for it is smuts and a sooty atmos- phere. Grime from coal costs us money when the same coal could be earning it for us ; for coal is our great- est asset, and we must use it to its greatest advantage. We should take a lesson from Mr. Grime doesn't pay 'I burn to make Britain Therm.
