We know the instruments of war used by the Britons were a sword, spear, shield and scythe. If they were not the manufacturers, how came they by these instruments? We cannot allow either they or the chariots were imported, because that will give them a much greater consequence: they must also have been well acquainted with the tools used in husbandry, for they were masters of the field in a double sense. Bad also as their houses were, a chest of carpentry tools would be necessary to complete them. We cannot doubt, therefore, from these evidences, and others which might be adduced, that the Britons understood the manufactory of iron. Perhaps history cannot produce an instance of any place in an improving country, like England, where the coarse manufactory of iron has been carried on, that ever that laborious art went to decay, except the materials failed; and as we know of no place where such materials have failed, there is the utmost reason to believe our fore-fathers, the Britons, were supplied with those necessary implements by the black artists of the Birmingham forge. Iron-stone and coal are the materials for this production, both which are found in the neighbourhood in great plenty. I asked a gentleman of knowledge, if there was a probability of the delphs failing? He answered, "Not in five thousand years." The two following circumstances strongly evince this ancient British manufactory:-- Upon the borders of the parish stands Aston-furnace, appropriated for melting ironstone, and reducing it into pigs: this has the appearance of great antiquity. From the melted ore, in this subterranean region of infernal aspect, is produced a calx, or cinder, of which there is an enormous mountain. From an attentive survey, the observer would suppose so prodigious a heap could not accumulate in one hundred generations; however, it shows no perceptible addition in the age of man. There is also a common of vast extent, called Wednesbury-old-field, in which are the vestiges of many hundreds of coal-pits, long in disuse, which the curious antiquarian would deem as long in sinking, as the mountain of cinders in rising. The minute sprig of Birmingham, no doubt first took root in this black soil, which, in a succession of ages, hath grown to its present opulence. At what time this prosperous plant was set, is very uncertain; perhaps as long before the days of Caesar as it is since. Thus the mines of Wednesbury empty their riches into the lap of Birmingham, and thus she draws nurture from the bowels of the earth. The chief, if not the only manufactory of Birmingham, from its first existence to the restoration of Charles the Second, was in iron: of this was produced instruments of war and of husbandry, furniture for the kitchen, and tools for the whole system of carpentry.
