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*

〃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
since (A。D。 120) the Roma
