Camden East (Ont.), Camden House Publishing, 1988. 72pp, paper, ISBN 0-920656-73-0 (cloth) $12.95, 0-920656-71-4 (paper) $9.95. Distributed by Firefly Books. CIP Grades 6 to 9 Reviewed by Alma Webster Volume 17 Number 1 1989 January What are clouds made of? When were clouds named? How much rain does a cloud hold? What are hurricanes? The answers to these and many other questions are found in Exploring the Sky by Day. Terence Dickinson has previously published seven titles on astronomy. The press release indicates that over the past twenty years he has published many articles in such magazines as Science Digest, Omni, and Astronomy. In twenty-nine chapters, progressing from the simplest concept of cloud formation to introductory weather forecasting, the author describes atmospheric phenomena including cloud types and names, precipitation, rainbows, thunderstorms and lightning, sky colour, haze, fog, frost, climatic zones, sundogs, aurora borealis, the moon, hurricanes and tornadoes. Although the work, with its introductory questions at the beginning of each chapter, appears to be designed for children to use independently, adults, too, will find it a useful, concise guide with adequate explanations. Easy access is provided by the detailed table of contents and index. This is a very attractive publication with outstanding reproduction of colour photographs, charts and diagrams, nearly two to a page. Every illustration complements the text, and an arrow ensures the proper identification. The layout and format are very pleasing, though the print is very small. Highly recommended.
