Fusion of the two elements of the Belgian population is observable in the Brabant country, in the vicinity of the linguistic frontier. Flemish laborers tend to invade Walloon settlements with the result that the number of inhabitants of Flemish speech is on the increase. A counter immigration of Walloons into Flemish villages also exists, with a corresponding addition to the number of French-speaking inhabitants wherever it takes place. The fact remains, however, that while Flemings acquire the French spoken by Walloons, it is an extremely rare occurrence for the latter to take up Flemish. In the course of time the Flemish immigrant in Walloon villages learns French, while the Walloon newcomer in Flemish villages manages to impose his language on his new neighbors. The net result is a gain for the French language. Today, after almost a hundred years’ quiescence, the Belgian question enters upon another critical stage. The problem is one of language in so far as the two languages spoken in the country represent the aims and interests of two different peoples. The Belgian question dates, in reality, from the treaty of Verdun of 843 and the partition of Charlemagne’s empire. Belgium then became the westernmost province of the transition state known as Lothringia. It was the hedge-country artificially created to act as a barrier between the peoples of Romanic and Teutonic speech. Its population, drawn from both elements, has been the alternate prey of French and German powers. But all of Belgium’s troubled history has been affected by the shape of the land. The only frontier with which the nation has been supplied by nature is the sea on the west. On the other three sides land features merge gradually with the main types in their neighborhood. Within Belgian territory, the lowlands of northern Europe join with the outliers of the uplifts of central Europe and their extension into France. Nowhere is the break sharp. The basin of the Schelde itself trespasses on the neighboring basins of the Rhine, the Meuse and the Somme.
