Show "Coal Savers." Various preparations are extensively advertised In this country at present which are presumed to contribute considerably con-siderably to the heating power of coal when applied In the prescribed doses, writes Consul General Robert P. Skinner, Skin-ner, London. The director of fuel research, re-search, in answer to an Inquiry as to the value of these preparations, states that these proprietary substances have been In the market a long time, but that there does not appear to be any genuine scientific evidence in support of the claims of their manufacturers. He concludes: "The nature of the substances makes It highly improbable that they have any effect whatsoever on the combustion of coal or other fuels when they are used in the quantities quan-tities prescribed." |
