Career
Swan"s first period in Siberia was relatively successful, working with Edward Stallybrass and Cornelius Rahmn, and preparing the Mongolian Bible. From Siberia he published Letters on Missions (1830) which the disappointed book reviewer of the Imperial Magazine found to be edifying, but totally lacking in any local colour from Siberia. However when the couple attempted to return to Siberia via Saint St. Petersburg, Swan was arrested and held until the end of 1833.
