Carl Lumholtz (1851-1922) was a Norwegian ethnographer and explorer who, soon after publishing an influential study of Australian Aborigines (also reissued in the Cambridge Library Collection), spent five years researching native peoples in Mexico. This two-volume work, published in 1903, describes his expeditions to remote parts of north-west Mexico, inspired by reports about indigenous peoples who lived in cliff dwellings along mountainsides. While in the US in 1890 on a lecture tour, Lumholtz was able to raise sufficient funds for the expedition. He arrived in Mexico City that summer, and after meeting the president, Porfirio Díaz, he set off with a team of scientists for the Sierra Madre del Norte mountains in the north-west of Mexico, to find the cave-dwelling Tarahumare Indians. Volume 1 covers the start of the expedition and Tarahumare life, etiquette and beliefs, as well as details of the natural history of this little-explored region.
