SMOKE ABATEMENT

[Tc the Editor of THE SPECTATOR.]

Sra,—I see in your issue of May 28th last certain questions arising on Mr. W. R. Gordon's letter under the heading of "Smoke Abatement." Apparently Mr. Gordon is acting under the premise that only coking coal can be used for carbonisation ; this is quite incorrect, as our particular company have carbonised many thousands of tons of non-coking coal. If this is a fact, as cannot in view of our experience be denied, the answers to the two questions are quite easily ascertained : (1) For domestic purposes non-coking coal can be with advantage carbonised, with the result that not only will the atmosphere be much cleaner, but in addition many advantages will accrue from the production of oil, spirit, creosote, &c., which are in great demand.

(2) In the event of non-coking coal being used, as suggested, all supplies of coking coal will still be available for industrial purposes as now.—I am, yours obediently,

RIC.HARD D. HARDY,
