To the ends of the earth: Four expeditions to the Arctic, the Congo, the Gobi, and Siberia

In the early decades of the 20th century, the American Museum of Natural History sponsored four of the last great expeditions to seek out the hidden places of the world. This heavily illustrated book recounts those expeditions to the Arctic, Siberia, Congo, and Gobi. Descriptions are also provided on the native cultures encountered during those expeditions.
