the pile, plates of malleable iron of a tough and flexible nature were formed, and under circumstances where there was no fuel but that furnished by the ore itself." [9]
The metal once discovered, many attempts would be made to give to that which had been the effect of accident a more unerring result. The smelting of ore in an open heap of wood or charcoal being found tedious and wasteful, as well as uncertain, would naturally lead to the invention of a furnace; with the object of keeping the ore surrounded as much as possible with fuel while the process of conversion into iron was going forward. The low conical furnaces employed at this day by some of the tribes of Central and Southern Africa, are perhaps very much the same in character as those adopted by the early tribes of all countries where iron was first made. Small openings at the lower end of the cone to admit the air, and a larger orifice at the top, would, with charcoal, be sufficient to produce the requisite degree of heat for the reduction of the ore. To this the foot-blast was added, as still used in Ceylon and in India; and afterwards the water-blast, as employed in Spain (where it is known as the Catalan forge), along the coasts of the Mediterranean, and in some parts of America.
It is worthy of remark, that the ruder the method employed for the reduction of the ore, the better the quality of the iron usually is. Where the art is little advanced, only the most tractable ores are selected; and as charcoal is the only fuel used, the quality of the metal is almost invariably excellent. The ore being long exposed to the charcoal fire, and the quantity made small, the result is a metal having many of the qualities of steel, capable of being used for weapons or tools after a comparatively small amount of forging. Dr. Livingstone speaks of the excellent quality of the iron made by the African tribes on the Zambesi, who refuse to use ordinary English iron, which they consider "rotten." [10] Du Chaillu also says of the Fans, that, in making their best knives and arrow-heads, they will not use European or American iron, greatly preferring their own. The celebrated wootz or steel of India, made in little cakes of only about two pounds weight, possesses qualities which no European steel can surpass. Out of this material the famous Damascus sword-blades were made; and its use for so long a period is perhaps one of the most striking proofs of the ancient civilization of India.
The early history of iron in Britain is necessarily very obscure. When the Romans invaded the country, the metal seems to have been already known to the tribes along the coast. The natives had probably smelted it themselves in their rude bloomeries, or obtained it from the Phoenicians in small quantities in exchange for skins and food, or tin. We must, however, regard the stories told of the ancient British chariots armed with swords or scythes as altogether apocryphal. The existence of iron in sufficient quantity to be used for such a purpose is incompatible with contemporary facts, and unsupported by a single vestige remaining to our time. The country was then mostly forest, and the roads did not as yet exist upon which chariots could be used; whilst iron was too scarce to be mounted as scythes upon chariots, when the warriors themselves wanted it for swords. The orator Cicero, in a letter to Trebatius, then serving with the army in Britain, sarcastically advised him to capture and convey one of these vehicles to Italy for exhibition; but we do not hear that any specimen of the British war-chariot was ever seen in Rome.
