This is a book about the forest. The way Jurgelis, an eight year old boy, sees forest. Growing up with his forester father Jogaila, he often visits the forest, experiences various adventures and learns a lot. For example, what do foresters do in their forests at different times of the year, what tools do they use. Does the roaring forest machinery, menacingly laying down one tree after another, always mean the death of the forest?
