The argument derived from the absence of iron in all our sepulchres also proves more than is desirable. The Danish antiquaries all admit that iron was not known in that country before the Christian era. Our antiquaries, from the testimony of Cæsar as to its use in war by the Britons, are forced to admit an earlier date, but it is hardly, if ever, found in graves. It is, on the other hand, perhaps correct to assume that its use was known in Egypt 3000 years before Christ; even if this is disputed, it certainly was known in the 18th dynasty, 15 centuries B.C., and generally in the Mediterranean shortly afterwards. If, then, the knowledge of the most useful of metals took 3000 or even 1500 years to travel across the continent of Europe, it seems impossible to base any argument on the influence these people exercised on one another, or on the knowledge they may have had of each others' ways. Or to take the argument in a form nearer home. When Cæsar warred against the Veneti in the Morbihan, he found them in possession of vessels larger and stronger than the Roman galleys, capable of being manœuvred by their sails alone, without the use of oars. Not only were these vessels fastened by iron nails, but they were moored by chain cables of iron. To manufacture such chains, the Veneti must have had access to large mines of the ore, and had long familiarity with its manufacture, and they used it not only for purposes on shore like the Britons, but in vessels capable of trading between Brest and Penzance--no gentle sea--and quite equal to voyages to the Baltic or other northern ports, which they no doubt made; it is asserted that, in 50 B.C., the Scandinavians were ignorant of the use of iron, though their country possessed the richest mines and the best ores of Europe. The truth of the matter appears to be that, a century or so before Christ, England and Denmark were as little known to Greece and Italy, and as little influenced by their arts or civilization, as Borneo or New Zealand were by those of modern Europe at the beginning of the last century. Even now, with all our colonization and civilizing power, we have had marvellously little real influence on the native races, and were our power removed, all traces would rapidly disappear, and the people revert at once to what they were, and act as they were wont to do, before they knew us.
