Of all colonial possessions of the European powers in the Pacific, German Samoa was by far the best-roaded; all roads up until 1942 had been constructed under German direction. The imperial grants from the Berlin treasury which had marked the first eight years of German rule were no longer needed after 1908. Samoa had become a self-supporting colony. Wilhelm Solf left Samoa in 1910 to be appointed Colonial Secretary at Berlin; he was succeeded as governor by Erich Schultz, the former chief justice in the protectorate. The Germans built the Telefunken Railroad from Apia onto the Mount Vaea for transporting building materials for the 120 m high mast of their Telefunken wireless station, which was inaugurated as planned on 1 August 1914, just a few days after the beginning of World War I.
