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。〃*

 'footnote。。。

Dr。 Livingstone brought with him to England a piece of the Zambesi

iron; which he sent to a skilled Birmingham blacksmith to test。

The result was; that he pronounced the metal as strongly resembling

Swedish or Russian; both of which kinds are smelted with charcoal。

The African iron was found 〃highly carbonized;〃 and 〃when chilled it

possessed the properties of steel。〃

 。。。'

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。



It is only in the tumuli along the coast; or in those of the

Romano…British period; that iron implements are ever found; whilst in

the ancient burying places of the interior of the country they are

altogether wanting。  Herodian says of the British pursued by Severus

through the fens and marshes of the east coast; that they wore iron

hoops round their middles and their necks; esteeming them as

ornaments and tokens of riches; in like manner as other barbarous

people then esteemed ornaments of silver and gold。  Their only money;

according to Caesar; consisted of pieces of brass or iron; reduced to

a certain standard weight。*

HOLINSHED; i。 517。  Iron was also the currency of the Spartans; but it

has been used as such in much more recent times。  Adam Smith; in his

Wealth of Nations (Book I。 ch。 4; published in 1776); says; 〃there is

at this day a village in Scotland where it is not uncommon; I am

told; for a workman to carry nails; instead of money; to the baker's

shop or the alehouse。〃

It is particularly important to observe; says M。 Worsaae; that all

the antiquities which have hitherto been found in the large burying

places of the Iron period; in Switzerland; Bavaria; Baden; France;

England; and the North; exhibit traces more or less of Roman

influence。

The Romans themselves used weapons of bronze when they could not

obtain iron in sufficient quantity; and many of the Roman weapons dug

out of the ancient tumuli are of that metal。  They possessed the art

of tempering and hardening bronze to such a degree as to enable them

to manufacture swords with it of a pretty good edge; and in those

countries which they penetrated; their bronze implements gradually

supplanted those which had been previously fashioned of stone。  Great

quantities of bronze tools have been found in different parts of

England;sometimes in heaps; as if they had been thrown away in

basketfuls as things of little value。  It has been conjectured that

when the Romans came into Britain they found the inhabitants;

especially those to the northward; in very nearly the same state as

Captain Cook and other voyagers found the inhabitants of the South

Sea Islands; that the Britons parted with their food and valuables

for tools of inferior metal made in imitation of their stone ones;

but finding themselves cheated by the Romans; as the natives of

Otaheite have been cheated by Europeans; the Britons relinquished the

bad tools when they became acquainted with articles made of better

metal。*

The Roman colonists were the first makers of iron in Britain on any

large scale。  They availed themselves of the mineral riches of the

country wherever they went。  Every year brings their extraordinary

industrial activity more clearly to light。  They not only occupied the

best sites for trade; intersected the land with a complete system of

well…constructed roads; studded our hills and valleys with towns;

villages; and pleasure…houses; and availed themselves of our

medicinal springs for purposes of baths to an extent not even

exceeded at this day; but they explored our mines and quarries; and

carried on the smelting and manufacture of metals in nearly all parts

of the island。  The heaps of mining refuse left by them in the valleys

and along the hill…sides of North Derbyshire are still spoken of by

the country people as 〃old man;〃 or the 〃old man's work。〃  Year by

year; from Dartmoor to the Moray Firth; the plough turns up fresh

traces of their indefatigable industry and enterprise; in pigs of

lead; implements of iron and bronze; vessels of pottery; coins; and

sculpture; and it is a remarkable circumstance that in several

districts where the existence of extensive iron beds had not been

dreamt of until within the last twenty years; as in Northamptonshire

and North Yorkshire; the remains of ancient workings recently

discovered show that the Roman colonists were fully acquainted with

them。



But the principal iron mines worked by that people were those which

were most conveniently situated for purposes of exportation; more

especially in the southern counties and on the borders of Wales。  The

extensive cinder heaps found in theForest of De anwhich formed

the readiest resource of the modern iron…smelter when improved

processes enabled him to reduce themshow that their principal iron

manufactures were carried on in that quarter*

 'footnote。。。

〃In the Forest of Dean and thereabouts the iron is made at this day

of cinders; being the rough and offal thrown by in the Roman time;

they then having only foot…blasts to melt the ironstone; but now; by

the force of a great wheel that drives a pair of Bellows twenty feet

long; all that iron is extracted out of the cinders which could not

be forced from it by the Roman foot…blast。  And in the Forest of Dean

and thereabouts; and as high as Worcester; there ave great and

infinite quantities of these cinders; some in vast mounts above

ground; some under ground; which will supply the iron works some

hundreds of years; and these cinders ave they which make the prime

and best iron; and with much less charcoal than doth the

ironstone。〃A。 YARRANTON; England's Improvement by Sea and Land。

It is indeed matter of history; that about seventeen hundred years
