 Believing that he had been called to a mission in education, he left his career in business to work full-time in the Covenant Mission school.In 1907, the Covenant mission sent him to Sweden to raise money for a seminary in China, a project that drew support also from the American-supported Covenant mission in North China and the Swedish-financed on in south China.The first book he published, "Eko från Kina" (Stockholm, 1921), was written in Swedish, which he translated into English as "Echoes from China" (Chicago, 1921).
