the tides and currents, about which he admits he could not obtain trustworthy information, Julius Cæsar saw no difficulty in invading the Island. There was not then that far-off line of storm-beaten ships which about two thousand years later stood between the great Corsican conqueror and the dominion of the world. All that mattered was to choose a good day in the fine August weather, throw a few legions on to the nearest shore, and see what there was in this strange Island after all. While Cæsar marched from the Rhine across Northern Gaul, perhaps through Rheims and Amiens, to the coast, he sent an officer in a warship to spy out the Island shore, and when he arrived near what is now Boulogne, or perhaps the mouth of the Somme, this captain was at hand, with other knowledgeable persons, traders, Celtic princes, and British traitors, to greet him. He had concentrated the forces which had beaten the Veneti in two ports or inlets nearest to Britannia, and now he awaited a suitable day for the descent.  What was, in fact, this Island which now for the first time in coherent history was to be linked with the great world? We have dug up in the present age from the gravel of Swanscombe a human skull which is certainly a quarter of a million years old. Biologists perceive important differences from the heads that hold our brains today, but there is no reason to suppose that this remote Palæolithic ancestor was not capable of all the crimes, follies, and infirmities definitely associated with mankind. Evidently, for prolonged, almost motionless, periods men and women, naked or wrapped in the skins of animals, prowled about the primeval forests and plashed through wide marshes, hunting each other and other wild beasts, cheered, as the historian Trevelyan finely says, 2 by the songs of innumerable birds. It is said that the whole of Southern Britain could in this period support upon its game no more than seven hundred families. Here indeed were the lords of creation. Seven hundred families, all this fine estate, and no work but sport and fighting. Already man had found out that a flint was better than a fist. His descendants would burrow deep in the chalk and gravel for battle-axe flints of the best size and quality, and gained survival thereby. But so far he had only learned to chip his flints into rough tools.
At the close of the Ice Age changes in climate brought about the collapse of the hunting civilisations of Old Stone Age Man, and after a very long period of time the tides of invasion brought Neolithic culture into the Western forests. The newcomers had a primitive agriculture. They scratched the soil and sowed the seeds of edible grasses. They made pits or burrows, which they gradually filled with the refuse of generations, and they clustered together for greater safety. Presently they constructed earthwork enclosures on the hilltops, into which they drove their cattle at nighttime. Windmill Hill, near Avebury, illustrates the efforts of these primitive engineers to provide for the protection of herds and men. Moreover, Neolithic man had developed a means of polishing his flints into perfect shape for killing. This betokened a great advance; but others were in prospect.
It seems that at this time “the whole of Western Europe was inhabited by a race of long-headed men, varying somewhat in appearance and especially in colouring, since they were probably always fairer in the north and darker in the south, but in most respects substantially alike. Into this area of long headed populations there was driven a wedge of round-headed immigrants from the east, known to anthropologists as ‘the Alpine race.’ Most of the people that have invaded Britain have belonged to the Western European long-headed stock, and have therefore borne a general resemblance to the people already living there; and consequently, in spite of the diversities among these various newcomers, the tendency in Britain has been towards the establishment and maintenance of a tolerably uniform long headed type.” 3
A great majority of the skulls found in Britain, of whatever age, are of the long- or medium-headed varieties. Nevertheless it is known that the Beaker people and other round-headed types penetrated here and there, and established themselves as a definite element. Cremation, almost universal in the Later Bronze Age, has destroyed all record of the blending of the long-headed and round-headed types of man, but undoubtedly both persisted, and from later traces, when in Roman times burials were resumed instead of cremation, anthropologists of the older school professed themselves able to discern a characteristic Roman-British type, although in point of fact this may have established itself long before the Roman conquest. Increasing knowledge has rendered these early categories less certain.
In early days Britain was part of the Continent. A wide plain joined England and Holland, in which the Thames and the Rhine met together and poured their waters northward. In some slight movement of the earth’s surface this plain sank a few hundred feet, and admitted the ocean to the North Sea and the Baltic. Another tremor, important for our story, sundered the cliffs of Dover from those of Cape Gris Nez, and the scour of the ocean and its tides made the Straits of Dover and the English Channel. When did this tremendous severance occur? Until lately geologists would have assigned it to periods far beyond Neolithic man. But the study of striped clays, the deposits of Norwegian glaciers, shows layer by layer and year by year what the weather was like, and modern science has found other methods of counting the centuries. From these and other indications time and climate scales have been framed which cover with tolerable accuracy many thousand years of prehistoric time. These scales enable times to be fixed when through milder conditions the oak succeeded the pine in British forests, and the fossilised vegetation elaborates the tale. Trawlers bring up in their nets fragments of trees from the bottom of the North Sea, and these when fitted into the climatic scale show that oaks were growing on what is now sixty fathoms deep of stormy water less than nine thousand years ago. Britain was still little more than a promontory of Europe, or divided from it by a narrow tide race which has gradually enlarged into the Straits of Dover, when the Pyramids were a-building, and when learned Egyptians were laboriously exploring the ancient ruins of Sakkara.
While what is now our Island was still joined to the Continent another great improvement was made in human methods of destruction. Copper and tin were discovered and worried out of the earth; the one too soft and the other too brittle for the main purpose, but, blended by human genius, they opened the Age of Bronze. Other things being equal, the men with bronze could beat the men with flints. The discovery was hailed, and the Bronze Age began.
The invasion, or rather infiltration, of bronze weapons and tools from the Continent was spread over many centuries, and it is only when twenty or thirty generations have passed that any notable change can be discerned. Professor Collingwood has drawn us a picture of what is called the Late Bronze Age. “Britain,” he says, “as a whole was a backward country by comparison with the Continent; primitive in its civilisation, stagnant and passive in its life, and receiving most of what progress it enjoyed through invasion and importation from overseas. Its people lived either in isolated farms or in hut-villages, situated for the most part on the gravel of river-banks, or the light upland soils such as the chalk downs or oolite plateaux, which by that time had been to a great extent cleared of their native scrub; each settlement was surrounded by small fields, tilled either with a foot-plough of the type still used not long ago by Hebridean crofters, or else at best with a light ox-drawn plough which scratched the soil without turning the sod; the dead were burnt and their ashes, preserved in urns, buried in regular cemeteries. Thus the land was inhabited by a stable and industrious peasant population, living by agriculture and the keeping of livestock, augmented no doubt by hunting and fishing. They made rude pottery without a wheel, and still used flint for such things as arrow-heads; but they were visited by itinerant bronze founders able to make swords, spears, socketed axes, and many other types of implement and utensil, such as sickles, carpenter’s tools, metal parts of wheeled vehicles, buckets, and cauldrons. Judging by the absence of towns and the scarcity of anything like true fortification, these people were little organised for warfare, and their political life was simple and undeveloped, though there was certainly a distinction between rich and poor, since many kinds of metal objects belonging to the period imply a considerable degree of wealth and luxury.”
The Late Bronze Age in the southern parts of Britain, according to most authorities, began about 1000 B.C. and lasted until about 400 B.C.
At this point the march of invention brought a new factor upon the scene. Iron was dug and forged. Men armed with iron entered Britain from the Continent and killed the men of bronze. At this point we can plainly recognise across the vanished millenniums a fellow-being. A biped capable of slaying another with iron is evidently to modern eyes a man and a brother. It cannot be doubted that for smashing skulls, whether long-headed or round, iron is best.
