The Junior Astronomy Club of the New York Museum of Natural History has a good opening wedge to an intelligent study of astronomy in this handbook. Step by step, through the seasons, the handbook takes one. Each step seems to grow out of its predecessor, and the charts and diagrams and simple text make it seem fascinating and straight sailing. The simpler constellations, the planets, the moon, meteors, double stars, solar observations, nebulae and clusters, amateur photography, variable stars, asteroids, hints on telescopic usage -- these are the main steps. The handbook should have wide circulation among all young people interested in the subject. An adult edition is to be issued, with additional material.
