It was the nearest approach to a universal language. So most of the constellations have Latin names. The English, French and German names are all different, but if all children would learn the Latin names they could understand one another. The Spring constellations every child should know are: LEO, the Lion LYRA, the Lyre CASSIOPEIA, the Queen in her Chair SCORPIO, the Scorpion URSA MAJOR, the Great Bear URSA MINOR, the Little Bear VIRGO, the Virgin [Illustration: THE SKY IN SUMMER] NOTE.--Every sky map is good for three months, in this way: If this is correct on June 1st at 10 P.M., it will be correct July 1st at 8 P.M., and August 1st at 6 P.M. This is because the stars rise four minutes earlier every night. Thus, after thirty days, any star will rise thirty times four minutes earlier, or 120 minutes, or two hours. Children need not learn all the Summer constellations. The most interesting are: AURIGA, the Charioteer CANIS MAJOR, the Big Dog CYGNUS, the Swan LYRA, the Lyre SCORPIO, the Scorpion [Illustration: THE SKY IN AUTUMN] NOTE.--This book tells how to find all the most interesting stars and constellations without maps, but many people prefer them. How to use star maps is explained under "The Sky in Winter." The Autumn constellations most interesting to children are: AQUILA, the Eagle AURIGA, the Charioteer CASSIOPEIA, the Queen in Her Chair CYGNUS, the Swan LYRA, the Lyre PERSEUS, Which Has the Arc TAURUS, the Bull URSA MAJOR, the Great Bear URSA MINOR, the Little Bear Transcriber's notes Page 124 "streams, runing" corrected to "streams, running" Page 127 "where he globe" corrected to "where the globe" Page 138 "ceatures to prove" corrected to "creatures to prove" Page 216 "this consellation is" corrected to "this constellation is" Page 203 "Everybirth day" corrected to "Every birthday"
