becomes, in turn, the parent of yet newer triumphs, so that at last, as in the present day, a single century sees vaster changes in the world of man than whole ages before it have done in far longer intervals. But the invention of bronze, or, in other words, the introduction of hard metal, was really perhaps the very greatest epoch of all, the most distinct turning-point in the whole history of humanity. True, some beginnings of civilisation were already found in the Newer Stone Age. Man did not then live by slaughter alone. Hand-made pottery and rude tissues of flax are found in neolithic lake dwellings in Switzerland. Agriculture was already practised in a feeble way on small open clearings, cautiously cleaved with fire or hewn with the tomahawk in the native forests. The cow, the sheep, and the goat were more or less domesticated, though the horse was yet riderless; and the pastoral had therefore, to some extent, superseded the pure hunting stage. But what inroad could the stone hatchet make unaided upon the virgin forests of those remote days? The neolithic clearing must have been a mere stray oasis in a desert of woodland, like the villages of the New Guinea savages at the present day, lying few and far between among vast stretches of primaeval forest. With the advent of bronze, everything was different; and the difference showed itself with extraordinary rapidity. One may compare the revolution effected by bronze in the early world, indeed, with the revolution effected by railways in our own time; only the neolithic world had been so very simple a one that the change was perhaps even more marvellous in its suddenness and its comprehensiveness. Metal itself implied metal-working; and metal-working brought about, not only the arts of smelting and casting, but also endless incidental arts of design and decoration. The bronze hatchets, for example, to take our typical implement, begin by being mere copies of the stone originals; but, as time goes on, they acquire rapidly innumerable improvements. First, metal is economized in the upper part which fits into the handle, while the lower or cutting edge is widened out sideways, so as to form an elegant and gracefully curved outline for the whole implement. Next come the flanged axes, with projecting ledges on either side; and then the palstaves with loops and ribs, each marking some new improvement in the character of the weapon, which the inventor would no doubt have patented but for the unfortunate fact that patents were as yet wholly unknown to Bronze Age humanity. Later still come the socketed hatchets of many patterns, with endless ingenious little devices for securing some small advantage to the special manufacturer. I can fancy the Bronze Age smith showing them off with pride to his interested customers: 'These are our own patterns--the newest thing out in bronze axes; observe the advantage you gain from the ribs and pellets, and the peculiar character which the octagonal socket gives to
