In the south, however, Somalis sent children to colonial and mission schools, and the graduates found civil service positions in the police force and as customs agents, bookkeepers, medical personnel, and teachers. These civil servants became a natural market for new retail businesses, restaurants, and coffee shops. Baidoa in the precolonial period had almost no permanent commercial establishments; by 1945, nearly 500 businesses were registered in the district. The new salaried class filled the ranks of the Somali nationalist movement after World War II. Literate in Italian or English, these urban Somalis challenged colonial rule. Furthermore, the Italian Somalia economy was even improved by the salt industry. Indeed, in 1930, an Italian firm invested capital to exploit salt deposits in Hafun, then called "Dante". By 1933-34, the Hafun salt works were producing more than 200,000 metric tons of salt, most of which was exported to the Far East. It was one of the main salt facilities in the world and had a cable-transport system of 24 km. In 2014 there were made plans to revive this huge factory In the 1930s Italian Empire, the Italian government promoted auto & moto competitions in order to increase the image of Italy (inside the colonial populations and in the world) as a technological country with state-of-the-art mechanical industry. Indeed, Italian Mogadiscio in 1938 was the second manufacturing city -after Italian Asmara- in the Eastern Africa's Italian Empire. The triangle Mogadiscio-Genale-Villabruzzi (actual Mogadishu-Afgoi- Jowhar) was the most developed area of the Italian colony, with one of the biggest vehicles concentration (per inhabitants) of all Africa: nearly 3000 vehicles in 1939. It is noteworthy that in British Somaliland there were no vehicles for civilians until after WWII (the few were only for military use ). Economic development during the Italian Trust Administration of Somalia In 1950, during the beginning of the ten years of the Trust Administration of Somalia under Italy, the "Cassa per la Circolazione Monetaria della Somalia" (Cassa for the monetary circulation of Somalia) was set up, established officially in a public law institution in 1954; in the same year the "Somali Credit" was established. At the same time, in British Somaliland, the National and Grindlais Bank (former Indian National Bank) opened some branches in Berbera and Hargeisa.
