The difference in the method of importing the ingredients makes thus no difference to the action of the crucible. Though the peoples now in process of formation in the New World are being recruited by mainly economic forces, it may be predicted they will ultimately harden into homogeneity of race, if not even of belief. For internationalism in religion seems to be again receding in favour of national religions (if, indeed, these were ever more than superficially superseded), at any rate in favour of nationalism raised into religion.
If racial homogeneity has not yet been evolved completely even in England--and, of course, the tendency can never be more than asymptotic--it is because cheap and easy transport and communication, with freedom of economic movement, have been late developments and are still far from perfect. Hence, there has never been a thorough shake-up and admixture of elements, so that certain counties and corners have retained types and breeds peculiar to them. But with the ever-growing interconnection of all parts of the country, and with the multiplication of labour bureaux, these breeds and types will be--alas, for local colour!--increasingly absorbed in the general mass. For fusion and unification are part of the historic life-process. "Normans and Saxons and Danes" are we here in England, yes and Huguenots and Flemings and Gascons and Angevins and Jews and many other things.
In fact, according to Sir Harry Johnston, there is hardly an ethnic element that has not entered into the Englishman, including even the missing link, as the Piltdown skull would seem to testify. The earlier discovery at Galley Hill showed Britannia rising from the apes with an extinct Tasmanian type, not unlike the surviving aboriginal Australian. Then the west of Britain was invaded by a negroid type from France followed by an Eskimo type of which traces are still to be seen in the West of Ireland and parts of Scotland. Next came the true Mediterranean white man, the Iberian, with dark hair and eyes and a white skin; and then the round-headed people of the Bronze Age, probably Asiatic. And then the Gael, the long-headed, fair-haired Aryan, who ruled by iron and whose Keltic vocabulary was tinged with Iberian, and who was followed by the Brython or Belgian. And, at some unknown date, we have to allow for the invasion of North Britain by another Germanic type, the Caledonian, which would seem to have been a Norse stock, foreshadowing the later Norman Conquest. And, as if this mish-mash was not confusion enough, came to make it worse confounded the Roman conquerors, trailing like a mantle of many colours the subject-races of their far-flung Empire.
