The former Director of the Museum of Natural History in New York has long proved his genius for sharing his experiences with his audience, whether platform or reading public. To this audience, his autobiography will be welcome news; it is good enough entertainment to widen that market. He tells of his start in the Museum, where scrubbing floors proved the opening wedge and enthusiasm and determination landed him on the read he had chosen to travel. His first claim to fame came with field research on wholes and the ""blubber and brime"" results brought him to the lecture platform and gave him mere chances of marine research. Intelligence work in the last war in China stimulated his curiosity about Central Asia, and he adventured in Wall Street for funda. Subsequent explorations brought realization of the growth of anti-foreignism, of Japan's expanding aims, of extensive publicity for his findings. Eventually, a stay-at-home job as Director ended in his becoming primarily a promoter, until his resignation. Fun and adventure-la-living, marrow squeaks, international social life, tremendous finds in his chosen field, all make good reading in popular science.
