Jewels from the Moon

Jewels from the Moon and The Meteor That Couldn't Stay is a 1964 children's science fiction book written by Eleanor Cameron and illustrated by Vic Dowd. Although the book features characters from Cameron's five Mushroom Planet books, it is tangential to the series. In fact, it is little known even to fans of the series because it was designed as a school reading book and was distributed in that manner by the American Book Company. The book is 64 pages long and features comprehension, discussion, and vocabulary questions after each story.
