[TO TIER EDTTOlt Or TIES " SPECTATOrt."]

SIR,—In your issue of October 9th your correspondent "Homo" inquires as to some satisfactory method by which coal-dust can be used on the domestic hearth. A. thoroughly efficient way is to procure some paper bags and fill them with some of the dust which has been well damped. If one of these bags is placed on any well-lit fire and left to burn through, it will last for a long time. Paper bags for this purpose are sold by Messrs. Hartley and Sons, Elmwood Mills, Claypit Lane, Leede:—I am, Sir, &c., W. C. 0-.
