Two-page piece from The Textile Mercury, 25 January 1890, describing a smoke-consuming device for boiler furnaces invented by Wallace McGuffin Greaves of Manchester. It quotes Dr. F. H. Bowman on the chemistry of combustion and smoke, then explains the appliance of incandescent non-conducting blocks placed on the furnace bridge with a perforated air plate, and reports claimed fuel savings of 15 to 20 percent. Two short notices follow: a request for finishing machinery for elastic webbing, and a note on telephone subscription charges in Manchester.
