For the better distribution of the subject I shall here retain the obsolete and otherwise inadmissible, because misleading, terms—Age of Stone, Age of Bronze, Age of Iron.[71] From the earliest times all the metals were employed, without distinction, for weapons offensive and defensive: besides which, the three epochs intermingle in all countries, and overlap one another; they are, in fact, mostly simultaneous rather than successive. As a modern writer says, like the three principal colours of the rainbow, these three stages of civilisation shade off the one into the other; and yet their succession, as far as Western Europe[72] is concerned, appears to be equally well defined with that of the prismatic colours, though the proportion of the spectrum may vary in different countries. And, as a confusion of ideas would be created, especially when treating of the North European Sword, by neglecting this superficial method of classification, I shall retain it while proceeding to consider the development of the White Arm under their highly conventional limits. I must, moreover, remark that the ternary division, besides having no absolute chronological signification, and refusing to furnish any but comparative dates, is insufficient. Concomitant with, and possibly anterior to, the so-called Stone Age, wood, bone, teeth, and horn were extensively used; and the use has continued deep into the metal ages. Throughout the lower valley of the River of the Amazons, where stone is totally wanting, primitive peoples must have armed themselves with another material. The hard and heavy trees, both of the Temperates and the Tropics, supplied a valuable material which could be treated simply by the use of fire, and without metal or even stone. Ramusio speaks of a sago-wood (_Nibong_ or _Caryota urens_) made into short lances by the Sumatrans: ‘One end is sharpened and charred in the fire, and when thus prepared it will pierce any armour much better than iron would do.’[73] The weapon would be fashioned by the patient labour of days and weeks, by burying in hot ashes, by steaming and smoking, by charring and friction, by scraping with shells and the teeth of rodents, and by polishing with a variety of materials: for instance, with the rasping and shagreen-like skin of many fishes, notably the ray; with rough-coated grasses, and with the leaves of the various ‘sandpaper-trees’ which are hispid as a cat’s tongue. And the first step in advance would be dressing with silex, obsidian, and other cutting stones, and finishing with pumice or with the mushroom-shaped corallines. I shall reserve for the next chapter a description of the _sabre de bois_, unjustly associated in the popular saying with the _pistolet de paille_. [Heading: _THE ‘BONE AGE.’_]
