A defense and an explanation of the tropics, this has a tidy-minded organization of its material. As a naturalist and with an early bias for more southern exposures, the author, in his work learned much, studied more of the warmer parts of the earth and has produced a book that does a lot to correct ignorance and misconceptions about the natural history of tropical man. The history of the discoveries of these regions; the varieties of mankind found there, and their civilizations; climate and clothing, tropical diseases and foods, forests and seasons and seas are all examined in relation to the impact and imprint of European culture and civilization. It offers great respect and great hope for what is thought of as an alien environment, and with the necessity of closer association with all peoples of the world, a proper and practical introduction to the areas between Capricorn and Cancer. Worthwhile study.
