Significant interest in the Arctic zone of Yakutia emerged at the end of the 20th century, when alluvial diamond deposits were discovered and began to be developed. The Arctic also has great prospects for hydrocarbons. At the present time there is a struggle for the development of natural resources of the Arctic, in this connection the relevance of the Arctic theme in Yakut literature as a whole increases. The Arctic is a mysterious, harsh northern land, which at the same time is very beautiful and dangerous. The land of White Silence fascinated and attracted explorers, travellers and romantics. Not only masters of words, but also artists, pedagogues, philosophers turned their eyes to the world of childhood as an integral part of people's life. Memories of childhood spent in the harsh northern land, of its courageous inhabitants - reindeer herders, hunters, fishermen - became the material for the literary works of the national writer of Yakutia, poet, prose writer Semyon Andreevich Popov-Tumat. In the works of the writer we get acquainted with the difficult life of the indigenous people of the North with their traditions, ways of life, with their feelings and dreams. We have analysed cycles of children's proses written by Semyon Tumat. In the stories of the writer contains a lot of cognitive information about the life of a simple man, a northerner, a master, transforming this harsh land and the amazing country of snow, endless sky, illuminated by the polar lights, the wonderful world of the Arctic. S. Tumat's prose does not glorify tenderness or mercy. In the works of the writer the most important themes are: the theme of childhood, upbringing, family, faith, willpower, the theme of nature, friendship and love. However, love for his native northern land, parents, the world of the Arctic appears in the works of a strong feeling, imprinted forever on the heroes. Semyon Andreevich approached to the disclosure of this issue individually; thinking over the style and details of the narrative, composition of the works, character and psychology of the heroes.
