CHAPTER I.

IRON AND CIVILIZATION.

"Iron is not only the soul of every other manufacture, but the main spring perhaps of civilized society."—FRANCIS HORNER.

"Were the use of iron lost among us, we should in a few ages be unavoidably reduced to the wants and ignorance of the ancient savage Americans; so that he who first made known the use of that contemptible mineral may be truly styled the father of Arts and the author of Plenty."—JOHN LOCKE.

When Captain Cook and the early navigators first sailed into the South Seas on their voyages of discovery, one of the things that struck them with most surprise was the avidity which the natives displayed for iron. "Nothing would go down with our visitors," says Cook, "but metal; and iron was their beloved article." A nail would buy a good-sized pig; and on one occasion the navigator bought some four hundred pounds weight of fish for a few wretched knives improvised out of an old hoop.

"For iron tools," says Captain Carteret, "we might have purchased everything upon the Freewill Islands that we could have brought away. A few pieces of old iron hoop presented to one of the natives threw him into an ecstasy little short of distraction." At Otaheite the people were found generally well-behaved and honest; but they were not proof against the fascinations of iron. Captain Cook says that one of them, after resisting all other temptations, "was at length ensnared by the charms of basket of nails." Another lurked about for several days, watching the opportunity to steal a coal-rake.

The navigators found they could pay their way from island to island merely with scraps of iron, which were as useful for the purpose as gold coins would have been in Europe. The drain, however, being continuous, Captain Cook became alarmed at finding his currency almost exhausted; and he relates his joy on recovering an old anchor which the French Captain Bougainville had lost at Bolabola, on which he felt as an English banker would do after a severe run upon him for gold, when suddenly placed in possession of a fresh store of bullion.

The avidity for iron displayed by these poor islanders will not be wondered at when we consider that whoever among them was so fortunate as to obtain possession of an old nail, immediately became a man of greater power than his fellows, and assumed the rank of a capitalist. "An Otaheitan chief," says Cook, "who had got two nails in his possession, received no small emolument by letting out the use of them to his neighbours for the purpose of boring holes when their own methods failed, or were thought too tedious."

The native methods referred to by Cook were of a very clumsy sort; the principal tools of the Otaheitans being of wood, stone, and flint. Their adzes and axes were of stone. The gouge most commonly used by them was made out of the bone of the human forearm. Their substitute for a knife was a shell, or a bit of flint or jasper. A shark's tooth, fixed to a piece of wood, served for an auger; a piece of coral for a file; and the skin of a sting-ray for a polisher. Their saw was made of jagged fishes' teeth fixed on the convex edge of a piece of hard wood. Their weapons were of a similarly rude description; their clubs and axes were headed with stone, and their lances and arrows were tipped with flint. Fire was another agency employed by them, usually in boat-building. Thus, the New Zealanders, whose tools were also of stone, wood, or bone, made their boats of the trunks of trees hollowed out by fire.

The stone implements were fashioned, Captain Cook says, by rubbing one stone upon another until brought to the required shape; but, after all, they were found very inefficient for their purpose. They soon became blunted and useless; and the laborious process of making new tools had to be begun again. The delight of the islanders at being put in possession of a material which was capable of taking a comparatively sharp edge and keeping it, may therefore readily be imagined; and hence the remarkable incidents to which we have referred in the experience of the early voyagers. In the minds of the natives, iron became the representative of power, efficiency, and wealth; and they were ready almost to fall down and worship their new tools, esteeming the axe as a deity, offering sacrifices to the saw, and holding the knife in especial veneration.

In the infancy of all nations the same difficulties must have been experienced for want of tools, before the arts of smelting and working in metals had become known; and it is not improbable that the Phoenician navigators who first frequented our coasts found the same avidity for bronze and iron existing among the poor woad-stained Britons who flocked down to the shore to see their ships and exchange food and skins with them, that Captain Cook discovered more than two thousand years later among the natives of Otaheite and New Zealand. For, the tools and weapons found in ancient burying-places in all parts of Britain clearly show that these islands also have passed through the epoch of stone and flint.

There was recently exhibited at the Crystal Palace a collection of ancient European weapons and implements placed alongside a similar collection of articles brought from the South Seas; and they were in most respects so much alike that it was difficult to believe that they did not belong to the same race and period, instead of being the implements of races sundered by half the globe, and living at periods more than two thousand years apart. Nearly every weapon in the one collection had its counterpart in the other,—the mauls or celts of stone, the spearheads of flint or jasper, the arrowheads of flint or bone, and the saws of jagged stone, showing how human ingenuity, under like circumstances, had resorted to like expedients. It would also appear that the ancient tribes in these islands, like the New Zealanders, used fire to hollow out their larger boats; several specimens of this kind of vessel having recently been dug up in the valleys of the Witham and the Clyde, some of the latter from under the very streets of modern Glasgow.[1] Their smaller boats, or coracles, were made of osiers interwoven, covered with hides, and rigged with leathern sails and thong tackle.

It will readily be imagined that anything like civilization, as at present understood, must have been next to impossible under such circumstances. "Miserable indeed," says Carlyle, "was the condition of the aboriginal savage, glaring fiercely from under his fleece of hair, which with the beard reached down to his loins, and hung round them like a matted cloak; the rest of his body sheeted in its thick natural fell. He loitered in the sunny glades of the forest, living on wild fruits; or, as the ancient Caledonians, squatted himself in morasses, lurking for his bestial or human prey; without implements, without arms, save the ball of heavy flint, to which, that his sole possession and defence might not be lost, he had attached a long cord of plaited thongs; thereby recovering as well as hurling it with deadly, unerring skill."

The injunction given to man to "replenish the earth and subdue it" could not possibly be fulfilled with implements of stone. To fell a tree with a flint
