OIL FROM COAL

[To the Editor of the SPECTATOR.] Sin,—I agree with all that " Consumer " says about Coalite, having used it continuously for open grates and hot-water- heating boiler for three years. In boilers it gives great heat with very slow combustion, and has never let me down. The only residue is a fine ash that can be carried away in a pail or sack. No clinker or other solids to remove. The makers ought to devise a system of delivery in the West Riding direct by road from a hopper to the consumer.—I am, Sir, &c., West Riddlesden Hall, near Keighley. JADES CRABTREE.
