CLEAN AIR

Sig,—'Your correspondent ' Engineer' writes in reply to my article on ' Clean Air' point- ing out how expensive the suggestions that I made may prove to be in practice. I have no reason to doubt the truth of everything that he Says and I have never suggested for a moment that the solution of the problem is an easy one, All I would say in reply, how- ever, is to give it as my opinion that all that he proposes—smokeless fuels, smokeless zones, etc.—will have no appreciable effect on the amount of sulphur dioxide discharged into the air of towns, and that is the only thing that really matters.—Yours faithfully,
