Berlin-led provincial government: The Provinzialverband would hence elect the "Oberpräsident" (head of the administration) and appoint representatives for the Reichsrat assembly in Berlin. Furthermore, the Provinzialverband officials could hence self determine how to spend the money they received from Berlin. From 1919 to 1930 Julius Lippmann served as governor of the province. Economy The border changes however caused a severe decline in the province's economy. Farther Pomerania was cut off from Danzig by the corridor. Former markets and supplies in the now Polish territories became unavailable. Farther Pomeranian farmers had sold their products primarily to the eastern provinces, that were now part of the Second Polish Republic. Due to high transport costs, the markets in the West were unavailable too. The farmers reacted by modernizing their equipment, improving the quality of their products, and applying new technical methods. As a consequence, more than half of the farmers were severely indebted in 1927. The government reacted with the Osthilfe program, and granted credits to favourable conditions. Stettin particularly suffered from a post-war change in trade routes. Before the territorial changes, it had been on the export route from the Katowice (Kattowitz) industrial region in now Polish Upper Silesia. Poland changed this export route to a new inner-Polish railway connecting Katowice with the new-build port of Gdynia within the corridor. As a counter-measure, Prussia invested in the Stettin port since 1923. While initially successful, a new economical recession led to the closure of one of Stettin's major shipyard, AG Vulcan Stettin, in 1927. The province also reacted to the availability of new traffic vehicles. Roads were developed due to the upcoming cars and buses, four towns got electric street cars, and an international airport was built in Altdamm near Stettin. The Pomeranian agriculture underwent a crisis. Programs were started to regain soil that had turned into swamps during the wartime, and even to establish new settlements by setting up settlement societies. The results were mixed. On the one hand, of farmland were settled with 8,734 new-build settlements until 1933. The settlers originated in Pomerania itself, Saxony, and Thuringia, also refugees from the former Province of Posen settled in the province. On the other hand, people left the rural communities en masse and turned to Pomeranian and other urban centers (Landflucht). In 1925, 50.7% of the Pomeranians worked in agricultural professions, this percentage dropped to 38.2% in 1933. With the economic recession, unemployment
