While, then, the various new states of the Peninsula are largely on a language basis, it should be noticed that Vlach-speaking peoples are scattered in groups in what is now Yugoslavia, and their numbers are variously estimated up to 250,000 or more. A considerable portion of Yugoslav Macedonia would probably consider itself Bulgar, and there are Greek elements in the Macedonian towns. Apart from Greek elements in the towns there is little that is alien in the reduced Bulgaria. Rumania has groups of many languages and traditions in all her newly acquired territories, and will need to exercise every care to prevent serious trouble in the near future. Yugoslavia includes a good deal of German, a little Italian, some Magyar, and some Rumanian, as well as Greek and more or less Bulgar elements, and a neutral commission should go carefully into the question of the Albanian boundaries. Italy's gains in Istria include a large Yugoslav element. Greek acquisitions have such a mixed population that little can be stated in detail. Finally, the Jewish element is of widespread importance in the towns; the Ashkenazim (Central European) element being very strong in Wallachia, and especially in Moldavia, and the Sephardim element (once Spanish) having {86} its head-quarters at Salonica. Before leaving the Balkan peoples it should be pointed out that, apart from their ancient hatreds, there is really every reason for mutual help between them. Rumania with its wheat and maize, Serbia with its forest-fed pigs and its plums and other fruits, Bulgaria with its mixed farming, and the Greek zones with their oil and wine, could supplement each other if suspicions were diminished and mutual credit arranged. The Greek element, with its long experience of commerce, would be a natural intermediary, as Venizelos saw when he planned a Balkan Federation; the obvious danger would be that of exploitation of producers by middlemen, especially if the latter were in a strong position politically.
