It’s very difficult to believe that wood buildings of long years old have kept till our days. How have they been able to stand for such long time? Russian builders have always had their secrets. Peasants of the Middle Ural made their habitable and economic construction with fur tree on the North and pine on the South. They tried to lay wood in a winter, as usual from the sixth of December to the second of February. They thought the forest was sleeping. But on the north of the Perm region in Cheldyn peasants prefer to cut wood in a yearly spring. Besides they thought that the new moon is the best period for cutting wood. Shell was made before sowing and dried up till building for two-three years. Corners of a sell were closed with birch bark. And peasants began to build the hut after drying out and collection moss only. It was also at the new moon. Houses were placed on the ground, podklet, and flat stones foundation.
