the old financial links with Vienna. Between Bohemia and the Carpathians, or more strictly the Tatra, is a physiographical trough such as so often occurs between fold-mountains (e.g. Tatra) and old blocks (e.g. Bohemia). It is occupied by the March (or Morava) river, is called Moravia, and is known as the Moravian gate, for through it Vienna communicates north-eastward not only with the Oder basin via Breslau, but also with the Vistula basin via Cracow. Somewhat more German than Bohemia the Moravian gate is still mainly Slavonic, with dialects grading eastwards towards Polish. There has been some difficulty in settling the limits of Moravia and Poland, the former having properly been allocated to the Czech, or better, Czechoslovak, state in the recent treaties. The dispute centred chiefly upon Děčin (formerly called Teschen), and was {64} solved by the cession to Czechoslovakia of the greater part of the coalfield and the railway which lies in Czechoslovakia, both before it enters and after it leaves Děčin territory. The town of Děčin itself goes to Poland. Not only does Czechoslovakia include Moravia, but it also stretches along the south flank of the Carpathians through a region of Slovak speech and rural life right on to the small district where Ruthenian just emerges west of the Carpathians. Thanks to their different language these Ruthenians are to have local autonomy under Czechoslovakia. The new state is thus of considerable size, and includes several dialects of Slav; it is both agricultural and industrial; it is keenly patriotic, and disposed, one hears, to split off from the Roman Church, just as it was so disposed in the Middle Ages. This state is contrasted to some extent with the majority of the Slavonic regions, in that, in spite of a large German element, there is more homogeneity and strength of cultural tradition throughout the Czech country than there is among many other Slav-speaking peoples. Farther east the pressure from the Asiatic grasslands and plateaux hindered the development of social settled life in the Middle Ages, when it was progressing farther west, and as a consequence the population of the towns is often different in tradition from that of the country. In the rural districts, again, the culture connexions of the ruling classes have often been different from those of the simple village folk. The result is that in many parts there have long been three social strata, often differing in language, religion, and political association. Upper Silesia has, in parts, German towns set in Polish country, and though some of the German element is of fairly recent introduction (and connected with industrial development), it nevertheless illustrates the social and political problem.
