of American and Australian Lutherans, the Neuendettelsau missionaries were able to continue their work and were allowed to travel to New Guinea again from 1928. The Steyler missionaries and the Steyler Missionary Sisters were also affected by the planned deportation. The Apostolic Delegate in Australia, Archbishop Bartolomeo Cattaneo (1866–1933), advocated the whereabouts of the German-speaking Catholic missionaries, from the orders of the Sacred Heart Missionaries (MSC), Marists (SM) and the Society of the Divine Word (SVD) ), who held this post in Australia from 1917 to 1933. The Archbishops of Sydney and New York also appealed to the Australian and American governments, asking that the deportation plans be withdrawn. To this day, German missionaries from the Protestant Neuendettelsauer Mission and the Catholic Sacred Heart of Jesus and Steyler missionaries work in Papua New Guinea. From 1926, after Germany joined the League of Nations, Germans could no longer be expelled from the territory of a League of Nations mandate. In the 1930s there were 4,500 foreigners in the Mandate New Guinea, four times more than in Papua, including 1,000 Chinese and 400 Germans. In 1921 gold was found in Wau. A few years later, as a result of the gold rush, gold seekers streamed through the port of Salamaua to Wau. In 1926 another, more productive gold field was found on Edie Creek near Wau. Since there were no roads yet and the transport over mountain paths was very laborious for the gold prospectors, it was necessary to fly in the heavy equipment. In 1937 and 1938, Bulolo Gold Dredging & Co and Guinea Airways moved more air freight with four Junkers G 31 cargo planes between Lae and Wau than in the rest of the world combined. Wisdom was replaced on June 13, 1933, by Brigadier General Thomas Griffiths. Brigadier General Walter Ramsay McNicoll followed on September 13, 1934. In Rabaul, the eruptions of the volcano Mount Tavurvur and its neighboring summit Matupit on the Vulcan Island on May 29, 1937, led to extensive destruction of the infrastructure and made the city almost uninhabitable. The seat of the administration of the territory was moved to Lae on the island of New Guinea. When Lae was destroyed by a Japanese air raid on January 20, 1942, Administrator McNicoll moved the administration to Wau. McNicoll contracted malaria and had to resign at the end of 1942.
