In the book "Southern and South-Central Africa. A Record of Fifteen Years of Missionary Activity Among Ancient Peoples," the author, Anna Frances Davidson, tells about her experiences and observations while working as a missionary in the exotic regions of Africa. She describes in detail the life and customs of the indigenous peoples with whom she communicated, talks about the difficulties and joys of working as a missionary in this region. The book is a very valuable document about the history of missionary activity and the cultural characteristics of the peoples of South and South-Central Africa.
