2. — Heated Air and Uncoked Coal for smelting Iron Ore. 



The journals have lately announced the discovery in France of a method of 

 smelting iron ore with billets of wood uncoked, from which a great saving of 

 expense is anticipated. This discovery will prove of high utility to the iron 

 smelters in foreign countries, especially in the north of Europe: but to the Bri- 

 tish smelters, it is vastly inferior in importance to the process now employed at 

 the Ciyde Iron Works, by which iron of an excellent quality is obtained at once 

 and in much larger quantity than formerly, by the employment of raw uncoked 

 coal. The agent in this remarkable amelioration of the smelting; process is heated 

 air, with which the blast in the furnace is kept up, instead of the cold air hitherto 

 propelled into the furnace ; the iron when withdrawn is much more fluid than
