Levallian's work is valuable as one of the first serious popular science opuses to cover life in such a remote area as the southern tip of the African continent. In Russian, literature on African studies, except for "legendary" and dubious information, at that time was very scarce. Levalyan reports a lot of data on the ethnography of the small peoples of the region in which he traveled, meeting with their representatives, leaders, observing their economic life, the level of social development.
