Intermixture between Nordic and Alpine stocks has spread the dominant broad-headedness of the Alpine over most of what is now Germany, but it is often combined with characters derived from the Nordic side (fair colouring and certain facial features), and a good deal of Nordic physique survives in the north-west and in Württemberg, as well as on the forested Thuringian hills. This spread of broad-headedness may be thought of alongside of the spread of modified High German and of the spread of southern rulers like the Hohenzollerns northwards, and it will then be seen how, in many ways, the south has permeated the north in more modern as well as in more remote times. It is useful to bear these things in mind as an offset against the danger of over-emphasizing the effects of the spread of Prussian political organizations over the south in the nineteenth century; it is also well to remember how much of that organizing power is traceable directly and indirectly to the Huguenot refugees finding homes in the hospitable Brandenburg of the seventeenth century. If the cathedrals are the sign and token of the people's effort in the Paris basin, the Universities, based upon that of Paris, are {43} the characteristic feature of civilization in the hill region of Germany, and, if prose is the triumphant expression of the French genius, lyrics and music are the glory of the German. The sharp criticism and startling clarity of French thought, growing where all the racial stocks of Europe jostle one another in a good wine country, stands in unceasing contrast to the more laborious stodginess of the more or less Alpinized German with his heavier menu in both food and drink. The quick enterprising Nordic element is present here and there; but it is the Alpine patience and appetite for detail that has increasingly dominated the psychology of the German people, working out into a power of combination that has had remarkable results in the industrial period. Just as we have had occasion to trace Romanization in the German belt, so we are able to follow Germanization in the Slavonic belt, but this time with differences. In the first place, there are settlements of Germans in forest clearings, as noted already for the plain east of the Elbe. But for the most part the western zone of the Slavonic belt had been Christianized, in large measure via Bohemia, before efforts at Germanization developed seriously, and so it was the next stage of social development that was affected by the German spread, namely the growth of towns. We thence find some areas of Germanized rural population, but also, through what have become Poland and Transylvania, German groups in the towns, and a similar movement into Russia has been a feature of the late eighteenth and nineteenth centuries.
