Ayan had only about 100 inhabitants and his duties as a doctor took up only about an hour per day. Thus Tiling could spend most of the day making scientific observations. One example is the temperature tables he made starting November 1847. He took temperatures three times per day, at 7 a.m., 2 p.m. and 9 pm, calculated monthly median values, and monthly high and low temperatures. He logged cloud cover, barometer readings, wind direction, and rainfall. He collected plants in the near vicinity of Ayan and according to his own conclusion "hardly missed one". His weather readings for Ayan are the oldest in Eastern Siberia. The flora of Ayan is one of the best documented in Siberia. In 1851, he and his family, now with four little children, took the boat from Ayan to Sachalin, Kamschatka, Sitka, Hawaii, Tahiti, around Cape Horn through the Atlantic Ocean back to Kronstadt. Back in Europe After the arrival in Europe, Tiling practised first in Riga. In 1854 he was the county surgeon for Wenden. Only when he moved to America he left this post. Second journey From 1863 to 1868, Tiling was surgeon in Sitka, Alaska. This was either again with the Russian-American Company, or with the Russian Government represented through the governor. Whether his wife and family accompanied him on this second journey is not entirely clear, yet it is very likely. She herself died in Riga in 1876, and also much later all their eight children. So nobody of the family stayed in the end in North America. At the time of the journey their youngest child Eduard was only six years old. Therefore, it can be assumed that at least his wife and some of the children came with him. In 1867 the US government purchased Alaska from Russia, yet Tiling stayed in Sitka. Most of the higher ranking Russian officials moved back to Europe. It is very likely that Tiling spoke English, his mother being English. His wife Anna was born in London and should have some degree of knowledge of the English language as well. There is no detailed written evidence about the later movements to San Francisco and Nevada City. Critical assessment Very obviously the collection and categorization of plants is core to Tiling's personality. This passion is with him throughout his life. From his various places of residence he send back plants, specimens, seeds, and
