1862 London Exhibition: Catalogue: Class I.: Nixon, Taylor and Cory
251. NIXON, TAYLOR, and CORY, Cardiff
Navigation steam coal supplied to H. M. yacht, Warrior, and Black Prince; and sections.
This coal is shipped at Cardiff, Newport, Swansea, Briton-Ferry, and Liverpool; it is wrought solely from the celebrated "Upper Four Feet Seam," in the Aberdare Valley, which is the best steam coal in the world: and is shipped by Nixon, Taylor, and Cory of Cardiff.
It is used on board Her Majesty's yacht; the frigates Warrior and Black Prince; and by the Cunard Line; the West India Royal Mail Company; the Peninsula and Oriental Company; the Hamburg and New York Company; the Liverpool and Montreal Ocean Steam Ship Company; the London and St. Petersburg Company, etc., etc. Reference can be made to any of these companies.
One pound of this coal has been found to evaporate more than 10 lbs. of water. It burns freely without smoke; is perfectly clear from iron pyrites, clod, shale, or other impurities; so much so that the engineer of the Atlantic Royal Mail Company's steamer, Prince Albert, during her passage of eight days from Galway to St. John's, Newfoundland, had only to clean the boiler fires twice.
This coal possesses a further advantage, viz., that the small that may be caused by breakage in transit will coke, or adhere sufficiently, so as when thrown into the furnace, to prevent its falling through the fire bars to waste. This quality of the Aberdare Steam Coal is unusual and most valuable.
