Raymond Ditmars was one of the early founders of the Bronx Zoo and nuts about reptiles and other animals. This is a book he wrote in 1935 which shows its age (Ditmars was not entirely sold on evolution for example, also he was racist towards people in other countries when he deigned to mention them) but is a fun read otherwise for some of his experiences dealing with the complexities of zoos, animals, and international travel so long ago. A few dull interludes about the weather towards the end seemed out of place.
